Androstenedione originates either from the conversion of Dehydroepiandrosterone ...

Endogenous and exogenous estrogens undergo oxidative metabolism by hepatic microsomal cytochrome P-450. Aromatic hydroxylation at either the C2 or C4 position is a major route of Estradiol metabolism in humans and other mammals, although there is less 4-hydroxylation than 2-hydroxylation. ...

Endogenous and exogenous estrogens undergo oxidative metabolism by hepatic microsomal cytochrome P-450. Aromatic hydroxylation at either the C2 or C4 position is a major route of Estrone metabolism in humans and other mammals, although there are less 4-hydroxylation than 2-hydroxylation events. ...

Androgen is the active metabolic product, 5alpha-Dihydrotestosterone, which is produced from the transformation of Testosterone catalyzed by the Steroid-5-alpha-reductase, alpha polypeptides 1 and 2 (S5AR1 and S5AR2) [1], [2]. ...

Estrogen receptor 1 (ESR1) is a major ligand-activated transcription factor, member of the family nuclear receptors [1]. ESR1 acts via two main pathways: a ligand-dependent and ligand-independent manner [2]. Activated by a ligand, ESR1 ...

In addition to the conventional hormone-dependent regulation of activity of Estrogen receptor alpha and beta (ESR1(nuclear) and ESR2 respectively), there is a cross-talk between signal transduction pathways and estrogen receptors [1]. Epidermal growth factor (EGF), ...
