Estrogen

Estrogen is a neurosteroid with protective and regenerative properties. Nerve growth factor differentiated PC12 neuronal cells have been shown to express both nuclear estrogen receptor ER alpha (genomic) and membrane estrogen receptor GPER (non-genomic), thus our aim is to differentiate which cellular pathways are employed by estrogen in neuritogenesis regulation. Here we treated such cells with 17-beta-Estradiol (E2) in a series of short and long incubation times. E2 treatments (10-6M) were compared with plasma membranous G protein-coupled estrogen receptor agonist G1 (10-6M) and antagonist G

…201, 2018), and that postmenopausal estrogen decline aggravates CIPN in patients undergoing paclitaxel-based chemotherapy (J Pharmacol Sci 146, 49, 2021). In this study, we analyzed estrogen modulation of upstream and downstream mechanisms of HMGB1. Female mice were subje

…In the brain, estrogen (17β-estradiol) establishes neural sex differences in many species and modulates mood, behavior, and energy balance in adulthood. To understand the diverse effects of estradiol on the brain, we profiled the genomic binding of estrogen receptor alpha (ERα), providing the first picture of the neural actions of any gonadal hormone receptor. To relate ERα target genes to brain sex differences we assessed gene expression and chromatin accessibility in the posterior bed nucleus of the st

…In rodents and nonhuman primates estrogen and progesterone influence the central nervous system across a range of spatiotemporal scales. Yet, their influence on the structural and functional architecture of the human brain is largely unknown. Here, I highlight findings from a series of dense-sampling neuroimaging studies from my laboratory designed to probe the dynamic interplay between the nervous and endocrine systems. Individuals underwent brain imaging and venipuncture every 12-24 hours for 30 consecutive days. These procedu

…in two ovarian produced hormones – estrogen and progesterone. As a result of these fluctuations, women experience different symptoms in their bodies – their immune system changes (Sekigawa et al, 2004), there are changes in their cardiovascular and digestive system (Millikan, 2006), as well as skin (Hall and Phillips, 2005). But these hormone fluctuations produce major changes in their behavioral pattern as well causing: anxiety, sadness, heightened irritability and anger (Severino and Moline, 1995) which
