Biochem/physiol Actions

2,3-Bis(4-hydroxyphenyl)-propionitrile (Diarylprepionitrile, DPN) is an ERβ-selective agonist; IC50 = 15nM. DPN protects WT and ARKO mice and significantly decreases IL-1β following LPS treatment in young adult-derived microglia. PPT (Cat. No.H6036, ERa agonist) enhances cell proliferation, while DPN inhibits it. PPT increases Bcl-2 expression, while DPN decreases it. DPN also elevates Bax expression. DPN induces a dose-dependent increase on vitellogenin synthesis. PPT and DPN are effective in dynamically, but differentially regulating intracellular calcium signaling in hippocampal neurons. DPN is more efficacious than PPT in potentiating a physiological concentration of glutamate-induced intracellular Ca2+ rise in these neurons. DPN prevents the development of prostatic hyperplasia and inflammation in testosterone-treated LuRKO mice.

There is strong evidence that the pro-inflammatory microenvironment during post-partum mammary involution promotes parity-associated breast cancer. Estrogen exposure during mammary involution drives tumor growth through neutrophils' activity. However, how estrogen and neutrophils influence mammary involution are unknown. Combined analysis of

Endogenous hydrogen sulfide (H2S) is a potent vasodilator and proangiogenic second messenger synthesized from L-cysteine by cystathionine β-synthase (CBS) and cystathionine γ-lyase (CTH). Estrogens are potent vasodilators that stimulate H2S biosynthesis in uterine arteries (UA) in vivo; however, the underlying
