Non-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 کاملProtective actions of sex steroid hormones in Alzheimer's disease.
Risk for Alzheimer's disease (AD) is associated with age-related loss of sex steroid hormones in both women and men. In post-menopausal women, the precipitous depletion of estrogens and progestogens is hypothesized to increase susceptibility to AD pathogenesis, a concept largely supported by epidemiological evidence but refuted by some clinical findings. Experimental evidence suggests that estr...

313 personal effort as well as personal desire must be active if an effective program is to develop. A case is made to the end that effort be directed to improve health during the latter half of the lifespan of the individual and not to continue focusing all attention on childhood and adolescence. The author urges us to reconsider policy in connection with a constructive medical program, to rec...
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 کاملThe correlation of anandamide with gonadotrophin and sex steroid hormones during the menstrual cycle
Objective(s): The purpose of this study was to investigate the change in plasma anandamide (AEA) levels throughout the normal menstrual cycle, and to analyze the relationship among AEA, sex steroids and gonadotrophins. Materials and Methods: The patients were fertile women with normal menstrual cycle, proposed to get in vitro fertilization (IVF) treatment due to oviduct obstruction or male infe...
