Differential regulation of KiSS-1 mRNA expression by sex steroids in the brain of the male mouse

…, EA Stoll, ML Gottsch, RE Braun, SM Eacker… - …, 2005 - academic.oup.com
Kisspeptins are products of the Kiss1 gene, which bind to GPR54, a G protein-coupled
receptor. Kisspeptins and GPR54 have been implicated in the neuroendocrine regulation of …

A nuclease that mediates cell death induced by DNA damage and poly (ADP-ribose) polymerase-1

…, R An, GK Umanah, H Park, K Nambiar, SM Eacker… - Science, 2016 - science.org
INTRODUCTION Poly(ADP-ribose) (PAR) polymerase-1 (PARP-1) is a nuclear enzyme
responding to oxidative stress and DNA damage. Excessive activation of PARP-1 causes an …

Understanding microRNAs in neurodegeneration

SM Eacker, TM Dawson, VL Dawson - Nature Reviews Neuroscience, 2009 - nature.com
Interest in the functions of microRNAs (miRNAs) in the nervous system has recently expanded

MicroRNA-223 is neuroprotective by targeting glutamate receptors

MM Harraz, SM Eacker, X Wang… - Proceedings of the …, 2012 - National Acad Sciences
Stroke is a major cause of mortality and morbidity worldwide. Extracellular glutamate
accumulation leading to overstimulation of the ionotropic glutamate receptors mediates neuronal …

Hormonal regulation of testicular steroid and cholesterol homeostasis

SM Eacker, N Agrawal, K Qian, HL Dichek… - Molecular …, 2008 - academic.oup.com
The male sex steroid, testosterone (T), is synthesized from cholesterol in the testicular Leydig
cell under control of the pituitary gonadotropin LH. Unlike most cells that use cholesterol …

Discovery of noncanonical translation initiation sites through mass spectrometric analysis of protein N termini

…, MS Kim, S Verbruggen, SM Eacker… - Genome …, 2018 - genome.cshlp.org
Translation initiation generally occurs at AUG codons in eukaryotes, although it has been
shown that non-AUG or noncanonical translation initiation can also occur. However, the …

Cultured networks of excitatory projection neurons and inhibitory interneurons for studying human cortical neurotoxicity

JC Xu, J Fan, X Wang, SM Eacker, TI Kam… - Science translational …, 2016 - science.org
Translating neuroprotective treatments from discovery in cell and animal models to the clinic
has proven challenging. To reduce the gap between basic studies of neurotoxicity and …

Androgen-dependent sertoli cell tight junction remodeling is mediated by multiple tight junction components

…, BE Smith, AR Greenlee, SM Eacker… - Molecular …, 2014 - academic.oup.com
Sertoli cell tight junctions (SCTJs) of the seminiferous epithelium create a specialized
microenvironment in the testis to aid differentiation of spermatocytes and spermatids from …
