Steroid metabolism in vitro by gonadal tissue from a true hermaphrodite

, 1979
The case of a true hermaphrodite, with a normal ovary and an ovotestis is presented. The ovotestis was removed and incubated in vitro with tritiated steroids (testosterone, dehydroepiandrosterone, pregnenolone and 17α-hydroxyprogesterone).

Genome-Wide Transcriptome Profiling Provides Insight on Cholesterol and Lithocholate Degradation Mechanisms in Nocardioides simplex VKM Ac-2033D

, 2020
Steroid microbial degradation plays a significant ecological role for biomass decomposition and removal/detoxification of steroid pollutants. In this study, the initial steps of cholesterol degradation and lithocholate bioconversion by a strain with ...

Metabolism of Oral Turinabol by Human Steroid Hormone-Synthesizing Cytochrome P450 Enzymes

, 2020
The human mitochondrial cytochrome P450 enzymes CYP11A1, CYP11B1, and CYP11B2 are involved in the biosynthesis of steroid hormones. CYP11A1 catalyzes the side-chain cleavage of cholesterol, and CYP11B1 and CYP11B2 catalyze the final steps in the ...

Entwicklung von effizienten Cytochrom-P450-abhängigen Biotransformations-Reaktionen im Ganzzellsystem für die Steroid-Hydroxylierung und Arzneimittelforschung

, 2008
Cytochromes P450 play a vital role in the steroid biosynthesis in the human adrenal gland, e.g. the production of hydrocortisone and aldosterone by CYP11B1 and CYP11B2, respectively. The steroid hydroxylases of the CYP11B family are important targets for

Functional expression of human mitochondrial CYP11B2 in fission yeast and identification of a new internal electron transfer protein, etp1

, 2002
Mitochondrial cytochrome P450 enzymes play a crucial role in the steroid biosynthesis in human adrenals, catalyzing regio- and stereospecific hydroxylations.

Distribution of progesterone-binding cytochrome P450 and steroid-17α-hydroxylase/C-17,20-lyase within different compartments of the rat testis

, 1983
Progesterone-binding capacity of cytochrome P450 and rate of progesterone consumption by cytochrome P450-dependent hydroxylases are highest in the Leydig cell fraction but are also detectable in the non-Leydig cell fraction of interstitial cells as well ...

Response differences in some steroid-sensitive hepatic enzymes in the fasting rat

, 1969
The activities of the glucocorticoid-inducible enzymes, tryptophan pyrrolase, tryptophan and tyrosine α-ketoglutarate transaminases, and phenylalanine and tryptophan hydroxylases, were measured during fasting and realimentation.
