Regulation of Expression of Steroidogenic Enzymes in Leydig Cells1

Payne, Anita H., Youngblood, Geri L.·1995·Biology of Reproduction

Abstract

The Leydig cell of the testis is the only cell in the male that has the capacity to synthesize testosterone from cholesterol. Testosterone is critical during fetal development for male sexual differentiation, and postnatally for initiation and maintenance of spermatogenesis and the expression of the male secondary sex characteristics. The biosynthesis of testosterone requires the activities of four enzymes, cholesterol side-chain cleavage enzyme (P450scc), 3 beta-hydroxysteroid dehydrogenase/delta 5-delta 4 isomerase (3 beta HSD), 17 alpha-hydroxylase/C17-20 lyase (P450(17 alpha)), and 17-ketosteroid reductase. The expression of these enzymes appears to be regulated by different mechanisms. The recent isolation of the mouse cDNAs and structural genes that encode these enzymes has enabled us to begin to investigate the regulation of their expression at the molecular level. This review discusses the regulation by cAMP and steroids of three enzymes in Leydig cells, P450scc, P450(17 alpha), and 3 beta HSD, as well as characterization of the promoters of the mouse genes that encode P450scc and P450(17 alpha).

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
