Effects of Steroid Hormones on Sex Differences in Cerebral Perfusion
Sex differences in the brain appear to play an important role in the prevalence and progression of various neuropsychiatric disorders, but to date little is known about the cerebral mechanisms underlying these differences. One widely reported finding is that women demonstrate higher cerebral perfusion than men, but the underlying cause of this difference in perfusion is not known. This study in...
متن کاملEffects of sex steroid hormones on neuromedin S and neuromedin U2 receptor expression following experimental traumatic brain injury
Objective(s): Neuroprotective effects of female gonadal steroids are mediated through several pathways involving multiple peptides and receptors after traumatic brain injury (TBI). Two of these peptides are including the regulatory peptides neuromedin U (NMU) and neuromedin S (NMS), and their common receptor neuromedin U2 receptor (NMUR2). This study investigates the effects of physiological do...
متن کاملNon-genomic actions of sex steroid hormones.
Steroid hormone receptors have been traditionally considered to act via the regulation of transcriptional processes, involving nuclear translocation and binding to specific response elements, and ultimately leading to regulation of gene expression. However, novel non-transcriptional mechanisms of signal transduction through steroid hormone receptors have been identified. These so-called 'non-ge...
متن کاملResponse: Cellular Uptake of Sex Steroid Hormones
of the 3H-label in their experiments is associated with the cells is difficult to interpret. Although some of the experiments by Hammes et al. are consistent with their “bound steroid” hypothesis (see, for example, Figure 2A), others are not (for example, see Figures 2B and 2C). At a concentration of 1 nM DHT plus 1 nM SHBG, 50% of the steroid exists in the free form. One nanomole of DHTSHBG an...
متن کاملEffects of steroid hormones on Neisseria gonorrhoeae.
Various steroids were tested for their effects upon gonococcal O2 consumption and glucose catabolism. The ability to inhibit gonococcal O2 uptake appeared to be related to the molecular configuration of the steroid. The presence of lipophilic groups enhanced inhibition, whereas the addition of hydrophilic groups markedly diminished inhibition. Steroid inhibition decreased with an increasing num...
