Abstract
Molecular differences between dopamine (DA) neurons may explain why the mesostriatal DA neurons in the A9 region preferentially degenerate in Parkinson's disease (PD) and toxic models, whereas the adjacent A10 region mesolimbic and mesocortical DA neurons are relatively spared. To characterize innate physiological differences between A9 and A10 DA neurons, we determined gene expression profiles in these neurons in the adult mouse by laser capture microdissection, microarray analysis and real-time PCR. We found 42 genes relatively elevated in A9 DA neurons, whereas 61 genes were elevated in A10 DA neurons [>2-fold; false discovery rate (FDR) <1%]. Genes of interest for further functional analysis were selected by criteria of (i) fold differences in gene expression, (ii) real-time PCR validation and (iii) potential roles in neurotoxic or protective biochemical pathways. Three A9-elevated molecules [G-protein coupled inwardly rectifying K channel 2 (GIRK2), adenine nucleotide translocator 2 (ANT-2) and the growth factor IGF-1] and three A10-elevated peptides (GRP, CGRP and PACAP) were further examined in both α-synuclein overexpressing PC12 (PC12-αSyn) cells and rat primary ventral mesencephalic (VM) cultures exposed to MPP+ neurotoxicity. GIRK2-positive DA neurons were more vulnerable to MPP+ toxicity and overexpression of GIRK2 increased the vulnerability of PC12-αSyn cells to the toxin. Blocking of ANT decreased vulnerability to MPP+ in both cell culture systems. Exposing cells to IGF-1, GRP and PACAP decreased vulnerability of both cell types to MPP+, whereas CGRP protected PC12-αSyn cells but not primary VM DA neurons. These results indicate that certain differentially expressed molecules in A9 and A10 DA neurons may play key roles in their relative vulnerability to toxins and PD.
INTRODUCTION
Major unsolved problems for most neurodegenerative diseases include determining specific factors that cause relative vulnerabilities of neuronal populations. This problem is exemplified by Parkinson's disease (PD), in which there is relative vulnerability even among neighboring midbrain populations of neurons releasing the same neurotransmitter, dopamine (DA).
DA neurons in the ventral midbrain consist of two main groups: the A9 group in the substantia nigra (SN) and the A10 group in the medial and ventral tegmentum (1). A9 and A10 DA neurons project to different anatomical structures and are involved in distinct functions. A9 DA neurons mainly project to the dorsolateral striatum, involved in the control of motor functions, whereas A10 DA neurons provide connections to the ventromedial striatum, limbic and cortical regions, involved in reward and emotional behavior. In addition to the distinct axonal projections and differences in synaptic connectivity, these groups of DA neurons exhibit differences in neurochemistry and electrophysiological properties (2,3), illustrating the functional differences despite similar neurotransmitter identity.
The most prominent neuropathology of PD is degeneration or dysfunction of midbrain DA neurons. Most PD cases are sporadic, for which a combination of environmental and genetic factors is the proposed etiology (4,5). The remaining cases are familial PD and caused by monogenic mutations on molecules such as α-synuclein (6) ubiquitin C-terminal hydrolase-1 (7), parkin (8), DJ-1 (9) and PINK1 (10) or, in the case of α-synuclein, also by triplication of the wild-type gene (11). Strikingly, and independent of specific etiology, 9 DA neurons are preferentially affected in PD and A10 DA neurons relatively spared (12–15). Similar patterns of degeneration appear in rodents and primate models of PD (13,16,17), indicating that the physiological differences between A9 and A10 DA neurons may be conserved between species.
Postmortem analyses of human PD brains demonstrate a selective cell loss of the A9 DA neuron group with a survival rate of ∼10% (14,18–20), whereas the A10 group is largely spared with a survival rate of ∼60% even in severe cases (14,21,22). This indicates that A9 DA neurons are more vulnerable to intrinsic and/or extrinsic factors causing degeneration in PD. In addition, three regional gradients of neurodegeneration in the dorso-ventral/rostro-caudal/medio-lateral axis have been reported in PD. Caudally and laterally located ventral DA cells within A9 DA neurons are the most vulnerable cells in PD (14,15). In contrast, the medial and rostral part of DA cell subgroups within A10 DA neurons (i.e. rostral linear nucleus, RLi) are the least affected (5–25% cell loss) (14,22).
Certain proteins differentially expressed in A9 and A10 DA neurons may play critical roles in susceptibility to or protection against neurodegenerative processes in PD. Previous studies have reported several proteins that are differentially expressed in A9 and A10 DA neurons. For example, calbindin D28K, an intracellular calcium binding protein has been used to distinguish resistant from vulnerable DA neurons in PD patient brain and animal models of PD, because it is colocalized in the resistant DA population (mostly A10 DA neurons) (23–25). Another of these proteins is G-protein-gated inwardly rectifying K+ channel (GIRK), which generates a slow inhibitory postsynaptic potential (IPSP) in DA neurons via activation of D2 or GABAB receptors and controls the membrane excitability of DA neurons. This can modulate the release of DA from synaptic terminals of DA neurons to the striatum. Among four isoforms of GIRK, only GIRK2 is exclusively expressed in the vulnerable DA neurons (mostly A9 neurons) (26,27), and it has been implicated in A9 DA neuron pathology in weaver mice (28–30).
The general hypothesis for this kind of exploration is that idiopathic, environmental and genetically driven processes culminating in neurodegenerative diseases are present in most cellular systems, but only reach a pathological threshold in very specific and characteristic neuronal populations (31,32). To determine the critical molecular differences that could result in vulnerability or provide opportunities for neuroprotection, we characterized the gene expression profiles of A9 and A10 DA neurons from adult mouse midbrain by laser capture microdissection (LCM) followed by microarray analysis and validation using real-time PCR. Some of the molecules from this analysis were then examined for functional relevance using PD-related in vitro cellular bioassays.
RESULTS
Gene expression profiles of A9 and A10 DA neurons based on LCM and microarray analysis
In our experiments, midbrain A9 and A10 DA neuronal groups were identified by rapid TH-immunostaining designed to minimize RNA degradation in tissue sections and microdissected by LCM using anatomical criteria (Fig. 1A–1D) as described in Materials and Methods. Using real-time PCR, we validated the quality of the extracted RNA samples by confirming the mRNA levels of GIRK2 known to be elevated in A9 DA neurons (26,27) and calbindin D28K known to be elevated in A10 DA neurons (23–25) (Fig. 1E). Glial fibrillary acidic protein (GFAP) was undetectable in both A9 and A10 samples, demonstrating the purity of the LCM samples (data not shown). To investigate the molecular differences between DA neurons located in the A9 and A10 midbrain regions, we performed microarray analysis to compare the gene expression profiles of A9 and A10 DA neurons. In total, five biological replicates from A9 and six biological replicates from A10 regions of mouse brain were analyzed on an Affymetrix Murine 430A high-density oligonucleotide array, which currently queries 22 000 murine probe sets. Paired hybridization results between replicates of A9 (Fig. 1F) and A10 (Fig. 1G) samples demonstrated the reproducibility between the biological replicates. The distribution of gene expression signals from the combined data of the A9 and A10 series displayed similarity and even distribution of A9-elevated and A10-elevated genes in the plot (Fig. 1H). Only a small number of genes were differentially expressed. Forty-two genes had >2.0-fold elevation of mRNA levels in A9 compared with A10 DA neurons (Table 1) and 221 genes had >1.5-fold elevation (FDR<1%) (Supplementary Material, Table S1). Sixty-one genes had >2.0-fold elevation of mRNA levels in A10 compared with A9 DA neurons (Table 1) and 167 genes had >1.5-fold elevation (FDR<1%) (Supplementary Material, Table S1). We validated the microarray analysis in two ways. First, we verified previously reported gene expression differences reported between A9 and A10 DA neurons. For example, Raldh1 (33) was elevated in A9 neurons and calbindin D28K (23–25) and cholecystokinin (34,35) were elevated in A10 DA neurons (Supplementary Material, Table S1). The known A9-elevated molecule, GIRK2, was confirmed only by real-time PCR as mentioned earlier [2.78-fold more expressed in A9 DA neurons (SEM±0.94)], because GIRK2 gene is not represented in the microarray chips used in this study. Secondly, using real-time PCR of laser-captured RNA samples, we quantified the mRNA levels of several genes from our microarray analysis to confirm gene expression patterns (Table 2). We chose to validate genes from various functional categories with potential association to relative vulnerability. Among the 16 genes tested, none failed validation by quantitative PCR. To gain insight into the biological relevance of differential A9/A10 gene expression, we analyzed genes that exhibited significant differences (FDR<1%) with Onto-Express (OE) software, which systematically translates genetic input into functional profiles (36). Genes from several categories showed interesting differences among cell groups. Genes related to metabolism (Fig. 2A) and genes encoding mitochondrial proteins (Fig. 2B) were elevated in A9 DA neurons compared with A10 DA neurons. Genes involved in protein, lipid and vesicle-mediated transport, but not ion transport, were also elevated in A9 DA neurons (Fig. 2C). Several genes related to small GTPase-mediated signaling and synaptic vesicle recycling, including RAB and RAS proteins (37), were elevated in A9 DA neurons (Supplementary Material, Table S1) and genes related to neuropeptide and hormone activity and axon guidance were elevated in A10 cells (Table 3). Intriguingly, certain opposing molecular functional categories exhibited inverse expression patterns in A9 and A10 DA neurons. For example, gene expression of proteases and phosphatases was elevated in A9 DA neurons, whereas inhibitors of proteases and phosphatases were elevated in A10 DA neurons (Table 3). Two pro-apoptotic genes, caspase 7 and Bcl2-like 11 (38), were elevated in A9 neurons (Table 3).
Altered vulnerability of α-synuclein overexpressing PC12 cells and primary VM cultures by molecules elevated in A9 DA neurons
To investigate and to efficiently screen candidate genes with functional relevance to PD-related vulnerability, we used inducible α-synuclein overexpressing PC12 cells (PC12-αSyn) (39) in combination with MPP+ treatment. This cell culture model combines two features of PD-related pathogenetic mechanisms: MPP+-induced mitochondrial complex I inhibition (40) and α-synuclein overexpression (11). We first established that overexpression of α-synuclein increased the susceptibility of PC12 cells to MPP+. There were 32% (SEM±2.6), 66% (SEM±3.8) and 20% (SEM±3.8) increases in LDH release at 1, 2.5, and 5 mm MPP+, respectively, when compared with control PC12 cells (P<0.05; n=4). We then investigated GIRK2, which is known to be elevated in A9 DA neurons (26,27) and linked to the degeneration of A9 DA neurons in the weaver mouse (26,41,42). We tested whether an increase in GIRK2 expression levels could modulate vulnerability to MPP+ in PC12-αSyn. Lentivirus-mediated overexpression of GIRK2 in PC12-αSyn (Fig. 3A and 3B) resulted in significantly increased vulnerability at low (1 mm) and high (5 mm) concentrations of MPP+ when compared with control (eGFP-transduced) cells (Fig. 3C). Then, we characterized GIRK2 expression in TH-positive cells of primary VM cultures (Fig. 3D and 3E). These cultures contained a mixed cell population of A9- and A10-like DA neurons and ∼40% of the TH-positive neurons at 5 days in vitro were GIRK2-positive by immunocytochemistry (Fig. 3E). The number of TH-positive/GIRK2-positive cells was reduced following MPP+ treatment, presumably reflecting vulnerability to this mitochondrial toxin when compared with TH-positive/GIRK2-negative cells (Fig. 3E). We also examined a role of a mitochondrial protein, adenine nucleotide translocase (ANT) 2, which was elevated in A9 neurons (Table 2) on MPP+ induced toxicity. ANTs appear to have an essential role in regulating permeability transition of mitochondria (43), which may in turn induce apoptosis (44). As ANT-2 mRNA was abundant in PC12 cells (data not shown), we inhibited the activity of ANT-2 by applying its inhibitor, bongkrekic acid (BA) in the presence of MPP+. BA was able to decrease MPP+-induced LDH release in a dose-dependent manner (Fig. 3F), indicating that higher expression of ANT-2 may increase susceptibility to MPP+ toxicity. In primary VM cultures, BA showed a significant protective effect on both GIRK2-negative and GIRK2-positive DA neurons (Fig. 3G). Interestingly, GIRK2-negative DA neurons appeared to be more sensitive to BA, as these A10-like DA neurons were maximally protected at lower doses than GIRK2-positive DA neurons (Fig. 3G).
On the basis of our comparative genetic profiles (Table 3), many growth factor-related genes were differentially expressed. Among these, we analyzed IGF-1 in both PC12-αSyn cells and primary VM cultures. IGF-1 was able to exert protective effects against MPP+ toxicity in both PC12-αSyn cells (Fig. 3H) and GIRK2-positive DA neurons of primary VM culture (Fig. 3I) in a dose-dependent manner.
Altered vulnerability of α-synuclein overexpressing PC12 cells and primary VM cultures by molecules elevated in A10 DA neurons
We also analyzed molecules that were more highly expressed in A10 DA neurons. Neuropeptides were chosen for analysis because they were a prominent class of molecules expressed relatively higher in A10 DA neurons (Tables 2 and 3). Gastrin releasing peptide (GRP), calcitonin/calcitonin gene-related peptide alpha (CGRP) and pituitary adenylate cyclase activating polypeptide (PACAP) were individually applied in the presence of MPP+ in PC12-αSyn cells or primary VM cultures. GRP exhibited a dose-dependent neuroprotective effect on both PC12-αSyn cells and GIRK2-positive DA neurons of primary VM cultures (Fig. 4A and 4B). CGRP was also able to significantly reduce MPP+-induced LDH release in PC12-αSyn cells (Fig. 4C). In primary VM culture, it had no effect on GIRK2-positive DA neurons, whereas it exhibited a significant toxic effect on GIRK2-negative DA neurons at higher doses (Fig. 4D). PACAP was able to reduce MPP+ toxicity in PC12-αSyn cells and in GIRK2-positive and GIRK2-negative DA neurons of primary VM cultures in a dose-dependent manner (Fig. 4F and 4E). These results support the hypothesis that certain molecules with differential expression patterns between A9 and A10 DA neurons may play key roles in protection and vulnerability of DA neurons.
DISCUSSION
In this study, we used LCM and genomic profiling to characterize the innate physiological differences between A9 and A10 DA midbrain neurons. Despite an overall high similarity in the gene expression profiles of these related DA neurons, several genes from different biological categories showed cell type-specific expression patterns. We examined some of these differentially expressed molecules using PC12-αSyn cells and primary VM cultures exposed to the PD-related neurotoxin, MPP+. Results from these bioassays showed that neuropeptides (GRP, CGRP and PACAP) expressed predominantly in A10 DA neurons protected against MPP+. Of genes elevated in A9 DA neurons, growth factors such as IGF-1 also decreased the vulnerability, whereas ANT-2 and GIRK2 appeared to increase cell toxicity. These results suggest that the study of genes with differential expression levels between A9 and A10 midbrain DA neurons can provide insights into specific neuroprotective and/or degenerative responses.
We propose at least two possible mechanisms whereby differential gene expression in A9 DA neurons could alter the vulnerability to neurotoxins. First, certain molecules may by themselves confer increased susceptibility in these neurons when their expression levels are relatively elevated. Elevated expression of such molecules may then decrease the threshold to extrinsic and intrinsic factors leading to cell-type specific degeneration (31,32). For example, GIRK2 and ANT-2 may render A9 DA neurons more vulnerable because of their pathophysiological actions on the membrane potential and on the mitochondrial permeability transition, respectively (discussed subsequently). Or pro-apoptotic molecules, such as caspase 7 and Bim (38) in A9 DA neurons (Table 3), may increase susceptibility of these neurons in pathological conditions. A second possibility is that A9 DA neurons may be more functionally dependent upon molecules with higher expression and therefore more vulnerable to fluctuation in their levels. In such cases, any insult, genetic polymorphisms or an age-dependent decrease in expression levels (45) that reduces the physiological functions of these molecules may be neurotoxic. An example of this class of A9-elevated molecule might be IGF-1, a known neuroprotective factor (46,47).
GIRK controls the neuronal membrane excitability by selectively permitting the flux of K+ ions near the resting membrane potential (48). Among four isoforms of GIRK, only GIRK2 is exclusively expressed in vulnerable DA neurons (26,27). GIRK2 generates a slow IPSP in DA neurons via activation of D2 or GABAB receptors and controls the membrane excitability of DA neurons. A potential role of GIRK2 in A9 DA neuron pathology in PD has been revealed in weaver mice, which have a spontaneous mutation in the GIRK2 gene and display PD-like patterns of DA neuron degeneration (28–30). Mutation in GIRK2 decreases the channel selectivity for K+, leading to the destabilization of the cell membrane (49). Our data suggest that elevated expression levels of GIRK2 may also contribute to the increased vulnerability of A9 DA neurons.
ANT is thought to play a role in the transport of ADP and ATP across the mitochondrial inner membrane (43,50). In addition, it is involved in the formation of the mitochondrial permeability transition pore (mPTP), a non-specific pore that is an important mediator of apoptosis (43,50). The mPTP opens in response to stimuli including reactive oxygen species and inhibitors of the electron transport chain, including MPP+ (51). In our study, blocking the function of ANT-2 by BA decreased the vulnerability of both PC12-αSyn cells and primary VM culture neurons to MPP+. This demonstrates that inhibition of ANT-2 is neuroprotective and, therefore, elevated ANT-2 expression levels in A9 DA neurons could confer increased susceptibility of these neurons to oxidative stress and toxins such as MPP+. It is interesting to note the toxic effect of BA at higher doses (Fig. 3G). It is unlikely that the toxic effect is due to non-specific inhibition of other proteins by BA as the doses used in our experiments are much lower than what is conventionally used in the field (44,52). However, it could be that the unusual dose–response curve of BA may depend on ANT's dual functions. Under pathological conditions, ANT is involved in forming the mPTP, which leads to cell death (44,50). Thus, blocking the mPTP-forming function of ANT would be protective to cells. However, under physiological conditions, ANT imports ADP from the cytosol and exports ATP synthesized by mitochondria back to the cytosol to be used as an energy source. Therefore, inhibition of ANT's physiological function could then be toxic (52). At the MPP+ concentration used in our experiment, some ANT molecules may be involved in mPTP formation, but the remainder may still function as ADP/ATP carriers. At higher doses, this normal physiological function of ANT could be inhibited, thus depleting the cellular energy source and deleteriously affecting cell survival.
IGF-1 is neuroprotective in brain hypoxia–ischemia (53,54), axotomy (55), age-induced hippocampal death (56) and glutamate-induced motor neuron death (57). It protects embryonic DA neurons from apoptosis (58) and dopaminergic cells from toxin-induced cell death in vitro (59). In addition, IGF-1 or the N-terminal tripeptide of IGF-1 protected DA neurons and improved functional deficits in 6-OHDA treated rats (46,47). Consistent with these findings, application of IGF-1 to the medium also reduced the MPP+ toxicity in PC12-αSyn cells and A9-like DA neurons of primary VM cultures in our study. This supports the notion that IGF-1 is an important neuroprotective factor which A9 DA neurons may depend on. Interestingly, plasma IGF-1 levels decrease with age (60) and a causal relationship between age-dependent decrease in IGF-1 and reduced cognitive brain function has been proposed in many studies (61). Taken together, the reduction of IGF-1 due to aging may contribute to increased vulnerability of A9 DA neurons in PD.
In our study, A10 DA neurons showed elevated transcription levels of several neuropeptides. We selected GRP, CGRP and PACAP to examine their roles in protecting DA cells from MPP+-induced toxicity. GRP is a neuroendocrine peptide known to act primarily in the enteric and central nervous systems, where it regulates diverse functions, from satiety and smooth muscle contraction to the release of other gastrointestinal hormones (62). It has also been studied extensively in the context of cancer cells where it plays a role as an autocrine growth factor (63,64). Although the presence of GRP in SN was reported many years ago (65), its function in DA neurons has not been described. In this study, our microarray data raised the possibility that GRP might be protective to DA neurons and we show here for the first time that GRP could reduce the toxic responses of both PC12-αSyn cells and primary mesencephalic DA neurons against MPP+. We thus suggest that GRP may contribute to the reduced susceptibility of A10 DA neurons in PD.
CGRP exerts multiple biological actions in the central nervous, gastrointestinal and cardiovascular systems (66,67). CGRP also influences the differentiation of immature DA neurons in primary VM cultures by inducing neurite outgrowth and increasing DA uptake per neuron, but not their normal rate of survival (68). In our study, CGRP reduced mitochondrial toxicity of PC12-αSyn cells. In primary VM cultures, it increased the susceptibility of A10-like DA neurons to the toxin in a dose-dependent manner, whereas it had no effect on the survival of A9-like DA neurons. These data raise the possibility that CGRP may not be a neuroprotective factor for DA neurons. However, it should be noted that primary VM cultures represent not adult but immature neurons. Given that there was a positive effect observed in PC12-αSyn cells, one cannot exclude a potential protective effect of CGRP in adult DA neurons in vivo.
PACAP belongs to the family of peptides containing secretin, glucagons and vasoactive intestinal peptide (VIP) (69,70). It is thought to act as a neurotrophic factor during development and as a neuroprotective factor against various insults (71,72). PACAP is also neurotrophic for TH-positive neurons in primary VM culture (73,74). In our in vitro assays, PACAP reduced the toxic responses of both the PC12-αSyn cells and the DA neurons of primary VM cultures to MPP+. In addition, the results from the primary VM cultures demonstrated that A9-like DA neurons were more responsive to the effects of PACAP than A10-like DA neurons. This result is further substantiated by a recent study in which injection of PACAP into the SN protected DA neurons and improved behavioral deficits in a rat model of PD (73). Another neuropeptide from the same class, VIP is also expressed higher in A10 DA neurons (Table 2) and its neurotrophic and neuroprotective effects in DA neurons against MPP+ have also been reported in a mouse model of PD (75). These data indicate that some A10-elevated molecules may contribute to the reduced vulnerability of A10 DA neurons, suggesting that these factors may be applied to protect A9 DA neurons. Interestingly, several neuropeptides, including PACAP and VIP, are known to be transported through the blood brain barrier via transmembrane diffusion (76), thus increasing their potential to be utilized in therapies for PD.
The microarray analyses also revealed that genes encoding energy-related metabolism and mitochondrial proteins are highly expressed in A9 DA neurons (Supplementary Material, Table S1). This is particularly interesting as mitochondrial dysfunction is thought to contribute to the etiology of PD (77). Elevated expression levels of these genes in A9 DA neurons are consistent with the notion that this neuronal population is highly energy (ATP)-dependent. Given the role of mitochondria in cellular energy metabolism, A9 DA neurons may be particularly susceptible to toxins such as MPP+ and rotenone (78) and to mutant α-synuclein or parkin which have been reported to cause mitochondrial dysfunction (79–81).
Another group of genes that are elevated in A9 DA neurons are genes related to vesicle-mediated transport, including RAB1, RAB3C, RAB6, RAB11A, RAB14, vacuolar protein sorting 35 and very low density lipoprotein receptor (Supplementary Material, Table S1). Efficient DA sequestration into vesicles protects DA neurons from the deleterious effects of DA oxidation (82). As A9 DA neurons have higher levels of the DA transporter than A10 or hypothalamic (A11, A13–A15) DA neurons (83–86), vesicle-mediated transport may be a more active and critical physiological process in this neuronal population. Interestingly, vesicle-mediated transport genes have recently been recognized as susceptibility factors in PD (45,87,88). In a genome-wide yeast screen for modifiers of α-synuclein-induced toxicity, modifiers were most prominently clustered in the vesicle-mediated transport and lipid metabolism categories (87). Furthermore, several vesicle-mediated transport genes, including several RAB genes, were found within genomic linkage regions for PD (88), and many vesicular transport genes were downregulated after age 40 in a recent study describing aging-dependent changes in human frontal cortex transcriptional profiles (45). This suggests that defective vesicular transport may contribute to the increased susceptibility of the aged patient population to neurodegenerative diseases. Taken together, A9 DA neurons may be particularly vulnerable to genetic or environmental factors that diminish the function of the vesicle-recycling machinery.
A recent paper published after the completion of our study described gene expression differences between catecholaminergic neurons in the rat (89). Although the study was done in rat tissue using a different microarray platform (14 800 element cDNA array), many of the genes the authors reported are consistent with the expression patterns seen in the mouse midbrain DA neuron microarray analysis reported here (Affymetrix oligonucleotide array with 22 000 probes). In addition to the microarray results, our study also includes the quantitative validation by real-time PCR and functional analyses, which illustrate that these differences in phenotypic gene expression may be relevant to neurotoxic responses.
In summary, we used LCM, microarray analysis and real-time PCR to determine gene expression profiles of A9 and A10 midbrain DA neurons and have begun to screen some of the molecules using in vitro bioassays. These data may offer opportunities for further in vivo modeling of neuroprotective and neurotoxic responses in midbrain DA neurons. Such scientific work may ultimately provide clues to pathogenetic mechanisms involved in PD and delineate neuroprotective and therapeutic interventions against this disease.
MATERIALS AND METHODS
Laser capture microdissection
Tissue preparation
Adult C57/B6 mice (Jackson Laboratory, West Grove, PA, USA) were anesthetized with intraperitoneal (i.p.) sodium pentobarbital (300 mg/kg) and decapitated. The brain was removed, snap-frozen in dry ice-cooled 2-methylbutane (−60°C). Ten micron-thick coronal sections of the midbrain were cut using a cryostat, mounted on LCM slides (Arcturus Engineering, Inc., Mountain View, CA, USA) and immediately stored at −70°C.
Quick immunostaining and dehydration of sections
A quick immunostaining protocol for TH was used to identify the DA neurons to be captured. First, the tissue sections were fixed in cold acetone for 5 min. The slides were then washed in phosphate-buffered saline (PBS), incubated with rabbit anti-TH (Pel-Freez Biologicals, Rogers, AR, USA; 1:25) for 4 min, washed in PBS and exposed to biotinylated anti-rabbit antibody (Vector Laboratories, Burlingame, CA, USA; 1:25) for 4 min. The slides were washed in PBS, incubated in ABC-horseradish peroxidase enzyme complex (Vectastain, Vector Laboratories) for 4 min and the staining was detected with the substrate, diaminobenzidine (DAB). Sections were subsequently dehydrated in graded ethanol solution (30 s each in water, 70% ethanol, 95% ethanol, 100% ethanol, and twice for 5 min in xylene). On the basis of our qualitative assessment, the sensitivity of the quick TH staining protocol did not differ from regular staining protocols, providing similar intensities of TH staining between A9 and A10 regions.
LCM of mouse midbrain tissue
The PixCell II System (Arcturus Engineering, Inc.) was used for LCM. Five-hundred to seven-hundred neurons were captured in each region of A9 and A10 in each animal. Five replicates of A9 samples were from five different mice and six replicates of A10 samples were from six different mice. As ventrolateral A9 DA neurons are the most vulnerable and medial A10 DA neurons the most resistant to degeneration, only ventrolateral A9 [ventrolateral SNc and SN pars reticulata (SNr)] and medial A10 DA neurons [central linear nucleus (CLi), interfascicular nucleus (IF), medial VTA, medial nucleus paranigralis (PN), medial nucleus parabrachialis pigmentosus (PBN)] were microdissected (Fig. 1A–1D).
Affymetrix GeneChip microarrays
Sample and array processing
Total RNA was separately extracted from the individual replicate samples using the PicoPure RNA isolation kit (Arcturus Engineering, Inc.). Nanogram quantities of total RNA from each sample were used to generate a high fidelity cDNA, which is modified at the 3′ end to contain an initiation site for T7 RNA polymerase. Upon completion of cDNA synthesis, all of the product was used in an in vitro transcription (IVT) reaction to generate aRNA. Up to 2 µg of aRNA was used for a second round of amplification which was initiated by random hexamer priming for first strand cDNA synthesis. The second round IVT contained biotinylated UTP and CTP which are utilized for detection following hybridization to the oligonucleotide microarray. Twenty micrograms of full-length cRNA, from both controls and enriched samples, were fragmented and hybridized to GeneChip arrays following the manufacturer's protocol. All samples were subjected to gene expression analysis via the Affymetrix Murine 430A high-density oligonucleotide array, which queries 22 000 mouse probe sets. Protocols for target hybridization, washing and staining were performed according to the manufacturer's protocol (http://www.affymetrix.com).
Data normalization and statistical analysis
Several complementary data analysis approaches were used to identify differentially expressed genes. The Gene Chip Operating System 1.0 (GCOS, Affymetrix) was employed to generate one approach to comparative analysis presented in this study. Distinct algorithms were used to determine the absolute call, which distinguishes the presence or absence of a transcript, the differential change in gene expression and the magnitude of change, which is represented as signal log ratio (on a log base 2 scale). The mathematical definitions for each of these algorithms can be found in the GCOS data analysis guide. Two additional low level analysis methods were applied to all data sets outside of the Affymetrix normalization schema. Iobion's GeneTraffic MULTI was used to perform Robust Multi-Chip Analysis (RMA), which is a median polishing algorithm used in conjunction with both background subtraction and quantile normalization approaches. For each normalization approach, statistical analysis using the Significance Analysis Tool set in GeneTraffic was utilized. A two class unpaired analytical approach employing Benjamini–Hochberg correction for false discovery rate (FDR) was used for all probe level normalized data. Gene lists of differentially expressed genes were generated from this output for functional analysis. All data were organized in a central database in the University of Rochester Functional Genomics Center and are accessible through the following URL (www.fgc.urmc.rochester). Following each of these normalization approaches, all genes differentially expressed were clustered based on biological relevance utilizing both hierarchical and K-means clustering techniques.
Real-time PCR for candidate gene validation
RNA samples from A9 and A10 DA neurons were reverse-transcribed into cDNA using Sensiscript reverse transcriptase (Qiagen, Valencia, CA, USA) and oligo dT as the primer. PCR reactions were set up in 25 µl reaction volume using SYBR Green PCR Master Mix (Applied Biosystems, Foster City, CA, USA). Primers for each candidate gene were designed using MacVacter 7.0 and used with a final concentration of 250 nm. For each primer pairs, duplicates of three to five independently collected A9 and A10 samples were compared to quantify relative gene expression differences between these cells using the 2−ΔΔCT method (90). Beta-actin was used as an internal control gene. β-actin was selected not only because it is widely used as a housekeeping gene, but also because it did not show differential expression between A9 and A10 DA neurons based on our microarray analysis. We also compared β-actin with other genes that do not show differential expression based on our microarray analysis, such as capping protein (NM_009798) and alex3 (NM_027870). A9/A10 ratios of these genes, when normalized with β-actin, were approximately 1, which means that all three genes are not differentially expressed between A9 and A10 DA neurons. On the basis of this, we decided to use β-actin as an internal control gene. Primers for candidate genes with approximately equal (within 5% difference) amplification efficiency to that of the internal control were chosen. The P-value for real-time PCR results was calculated by one-sample t-test.
Generation of GIRK2-expressing lentivirus
Construction of lentiviral vectors
The mouse GIRK2 cDNA (a gift from Dr David Clapham, Children's Hospital, Boston, MA, USA) was cloned into the lentiviral vector, pRRL.cPPT.PGK.GFP.W.Sin-18 vector (kindly provided by Drs R. Zufferey and D. Trono, University of Geneva, Switzerland) by exchanging the GFP gene with the GIRK2 cDNA and confirmed by sequence analyses.
Production of lentiviral vectors and cell transduction
The lentiviral vector system used in our studies was kindly provided by Drs R. Zufferey and D. Trono, University of Geneva, Switzerland. High titer of infectious lentiviral particles were produced in 293 T-cells using a four-plasmid transfection protocol (Current Protocols in Neuroscience, 2000, 4.21.1–4.21.12). For this, the following packaging plasmids pMDLg/pRRE (for gag and pol expression), pMD.G (for expression of the VSV-G env protein) and pRSV.Rev (for rev expression) were co-transfected with the recombinant pRRL.cPPT.GIRK2.W.Sin-18 vector to produce viral transduction units (TU). Virus supernatants were collected and filtered through a 0.2 µm filter and either used freshly, stored at −80°C or ultracentrifuged to obtain high concentrations of viral stocks. Virus titers were determined according to published protocols (91) measuring the viral capsid protein p24 by ELISA in collaboration with Dr C. Brander, AIDS Research Center, Massachusetts General Hospital. For in vitro transduction, PC12-αSyn were cultured directly in virus-containing media supplemented with 8 µg/ml polybrene.
In vitro functional analysis of candidate molecules
α-Synuclein overexpressing PC-12 cell culture
A PC12 cell line expressing wild-type human α-synuclein was used (kindly provided by Dr Peter Lansbury). α-Synuclein expressing PC12 cells were grown in Dulbecco's modified Eagle's medium (DMEM) (Invitrogen, Carlsbad, CA, USA) supplemented with 10% heat-inactivated horse serum, 5% heat-inactivated fetal calf serum (Hyclone, Logan, UT, USA), 4 mml-glutamine, streptomycin and penicillin G (Fisher, Pittsburgh, PA, USA). Cells were maintained at 37°C, in 5% CO2 humid atmosphere. For the bioassay, α-synuclein overexpressing PC-12 cells were treated with 1 mm MPP+ to determine the neuroprotective effects of BA, insulin growth factor-1 (IGF-1), CGRP alpha, GRP and PACAP molecules. Various doses of the molecules were applied to the cells 2 h prior to MPP+ treatment and after 24 h, supernatants were collected for measuring a cell-death related release of lactate dehydrogenase (LDH) using an LDH release assay kit (Roche, Indianapolis, IN, USA). BA was purchased from Sigma; IGF-1 from R&D and CGRP, GRP and PACAP from Calbiochem.
Primary VM cell culture
Primary cultures of DA neurons were obtained from E15 Sprague-Dawley rat (Charles River, MA, USA) ventral mesencephalon (VM). The dissected VM tissue was mechanically dissociated with a fine-polished pasteur pipette. The cells were resuspended in DMEM containing heat-inhibited horse serum (10%), glucose (6.0 mg/ml), penicillin, streptomycin and 2 mm glutamine (Gibco). Cell suspensions containing 4×105 cells were plated on coverslips in 24-well plates and precoated with a 1:500 diluted solution of polyornithine and fibronectin in 50 mm sodium borate (pH 7.4). For the MPP+ dose–response curves, cultures were treated at day 5 for 48 h with MPP+ at concentrations ranging from 0.1 to 10 µm. Neuropeptides, IGF-1 and BA were applied at various doses 2 h prior to 10 µm MPP+ treatment. After 48 h, cells were fixed in paraformaldehyde for immunostaining of TH and GIRK2.
Immunocytochemistry and stereology
Immunocytochemistry
Indirect immunofluorescence was performed on 4% paraformaldehyde fixed VM cultures. Fixed cells were incubated in a blocking solution consisting of 10% normal donkey serum (Jackson ImmunoResearch Laboratories Inc., West Grove, PA, USA) and 0.1% Triton X-100 (Sigma, St Louis, MO, USA) in 0.1 m PBS for 1 h at room temperature. Primary antibodies were diluted in blocking solution and added to the cells. The primary antibodies used were tyrosine hydroxylase (sheep anti-TH, 1:300, Pel-Freez Biologicals, Rogers, AK, USA) and GIRK2 (rabbit; 1:80, Alomone Laboratories, Jerusalem, Israel). After incubation at 4°C overnight, cells were rinsed three times in 0.1 m PBS for 5 min each before application of the secondary antibody solution for 1 h at room temperature. The secondary antibodies were diluted in 10% normal donkey serum in 0.1 m PBS. Secondary antibodies were Alexa Fluor 488 conjugated donkey anti-sheep and Alexa Fluor 594 conjugated donkey anti-rabbit (Molecular Probes, Eugene, OR, USA). After rinsing in triplicate for 10 min each in 0.1 m PBS, the cells were counterstained with 0.0005% Hoechst 33342 (Molecular Probes) in 0.1 m Tris buffered saline. The coverslips containing the fixed cells were then rinsed in 0.1 m PBS followed by distilled water and mounted onto slides using an aqueous mountant (Gel/Mount, Biomeda Corp., CA, USA). Control coverslips immunostained with secondary antibody only were used to assess specificity of the technique.
Stereology
Design-based stereology was performed by counters blinded to experimental groups on the stained coverslips using an integrated Axioskop 2 microscope (Carl Zeiss, Thornwood, NY, USA) and Stereoinvestigator image capture equipment and software (MicroBrightField, Williston, VT, USA). A contour was drawn around each coverslip to identify the area of interest. A physical dissector probe was utilized and counting frames were placed in a systematically random manner at ∼200 sites/coverslip. The resultant coefficient of error for the stereological counts was used to assess precision (P<0.05).
