3β-hydroxysteroid dehydrogenase isoforms in human aldosterone-producing adenoma

CTNNB1 Mutation in Aldosterone Producing Adenoma

Discoveries of somatic mutations permit the recognition of subtypes of aldosterone-producing adenomas (APAs) with distinct clinical presentations and pathological features. Catenin β1 (CTNNB1) mutation in APAs has been recently described and discussed in the literature. However, significant knowledge gaps still remain regarding the prevalence, clinical characteristics, pathophysiology, and outc...

Hypomethylation of CYP11B2 in Aldosterone-Producing Adenoma.

The purpose of this study was to evaluate the DNA methylation levels of steroidogenic enzyme genes in aldosterone-producing adenoma (APA) and the effects of gene mutations in APA on the DNA methylation levels. DNA methylation array analysis was conducted using nonfunctioning adrenocortical adenoma (n=12) and APA (n=35) samples, including some with a KCNJ5 mutation (n=21), an ATP1A1 mutation (n=...

Effects of genistein and equol on human and rat testicular 3β-hydroxysteroid dehydrogenase and 17β-hydroxysteroid dehydrogenase 3 activities

The objective of the present study was to investigate the effects of genistein and equol on 3β-hydroxysteroid dehydrogenase (3β-HSD) and 17β-hydroxysteroid dehydrogenase 3 (17β-HSD3) in human and rat testis microsomes. These enzymes (3β-HSD and 17β-HSD3), along with two others (cytochrome P450 side-chain cleavage enzyme and cytochrome P450 17α-hydroxylase/17-20 lyase), catalyze the reactions th...

Human 3β‐hydroxysteroid dehydrogenase type 1 in human breast cancer: clinical significance and prognostic associations

Active sex steroids including estrogens and androgens are locally produced from circulating inactive steroids by various steroid-metabolizing enzymes, and play pivotal roles in the progression of hormone-dependent breast cancers. Human 3β-hydroxysteroid dehydrogenase type 1 (3β-HSD type 1) is a critical enzyme in the formation of all classes of active steroid hormones, and is also involved in t...
