Inhibition of local estrogen synthesis in the hippocampus impairs hippocampal memory consolidation in ovariectomized female mice

0 | Jun 25 2018

Tuscher JJ et al. examined the role of hippocampal E2 synthesis in hippocampal memory consolidation. Using bilateral dorsal hippocampal infusions of the aromatase inhibitor letrozole, we first found that blockade of dorsal hippocampal E2 synthesis impaired hippocampal memory consolidation. We next found that elevated levels of E2 in the dorsal hippocampus observed 30min after object training were blocked by dorsal hippocampal infusion of letrozole, suggesting that behavioral experience increases acute and local E2 synthesis. Finally, aromatase inhibition did not prevent exogenous E2 from enhancing hippocampal memory consolidation, indicating that hippocampal E2 synthesis is not necessary for exogenous E2 to enhance hippocampal memory. Combined, these data are consistent with the hypothesis that hippocampally-synthesized E2 is necessary for hippocampus-dependent memory consolidation in rodents. [Read the Full Post]

MDV3100- AN ANTI PROSTATE CANCER AGENT

2459 | Apr 09 2012

ROLE OF ANDROGEN RECEPTORS Androgen receptors (ARs), a type of nuclear receptors that are involved in the regulation of expression of different types of genes that play role in the development and progress of male sexual characteristics. ARs can also be called as receptor subfamily number 3, C group, and member number 4 (NR3C4nuclear). Dihydrotestosterone or testosterone and androgenic hormones function as ligands for these receptors and are in turn translocated into the nucleus, where they directly or indirectly regulate the respective gene expression. Higher quantities of progestin inhibit these receptors. These receptors are known to effect many different types of genes and their expression e.g., AKT1, Cyclin D1, HDAC1, BRCA1, STAT3, SRC kinases and EGFR etc. they all are mostly cell cycle regulating proteins or oncoproteins which are malfunctioning in many different types of cancers.

OSTARINE

4245 | Apr 05 2012

MODULATORS OF ANDROGEN RECEPTORS: Androgenic compounds are famous for their uses in banned drugs for sportsmen but very few people have knowledge to link these compounds for therapeutic purposes. Although androgen receptor modulators have restricted legitimate uses compared to anabolic steroids, many of these are undergoing clinical trials, these Selective androgen receptor modulators (SARMs) proved to be far more specific in their activities as well. The increases in knowledge about these modulators lead to the assessment in preclinical and clinical studies against different diseases. The structural diversity has been increased dramatically due to more application of SARMs for various modifying levels of androgen. The ability of SARMs as therapeutics is reported to enhance by anabolic dissociation and androgenic activities. In elder age the muscle wasting is being cured by using SARMs therefore their uses at a larger scale lead to the better drug design. Receptors of androgen are altered in a pleiotropic way in order to produce promising drugs against ageing, andropause, hypogonadism, muscle wasting, sarcopenia and osteoporosis. Keeping in mind this potential, these SARMs are becoming famous as potent and novel therapeutics. [Read the Full Post]
