background: aqueous extract of winter cherry ( physalis alkekengi l; family of solanaceae) fruits (wcf) has long been recommended for fertility control by herbalists in iran. the effect of this extract on lowering serum progesterone levels has been reported previously.   objective: to study the effects of wcf extract on the activities of ovarian 3β-hydroxysteroid dehydrogenase (3β-hsd) responsi...

Steroid hormones are produced by the porcine uterus. We hypothesized that the uterus in pigs possesses active 3β-hydroxysteroid dehydrogenase/Δ(5)-Δ(4) isomerase (3β-HSD) responsible for progesterone and androstenedione production, that uterine steroids may supplement the amount of steroid hormones produced by embryos and corpus luteum and that these steroids are necessary for maintenance of pr...

In the present study, we report the mutation of the 3β-hydroxysteroid dehydrogenase (3β-HSD) gene in a family suffering from adrenocortical insufficiency. The index patient was clinically diagnosed with adrenocortical insufficiency. Peripheral venous blood (5 ml) was collected from the proband and 5 members of his family, and genomic DNA was extra...

Annexin A5 significantly stimulated testosterone secretion from rat Leydig cells in doseand time-dependent manners and increased mRNA and protein expression of StAR, P450scc, 3β-HSD and 17β-HSD but not 17α-hydrox...

Dehydroepiandrosterone (DHEA) is important for human health, especially for women. All estrogens and practically half of androgens are synthesized from DHEA in peripheral tissues. However, the mechanism and exact target tissues of DHEA biotransformation in the female are not fully clear. The present study showed that maximal content of androstenedione (AD) and testosterone (T) were observed at ...

The purpose of the study was to examine the effect of luteal macrophage conditioned medium (LMCM) on progesterone and estradiol production by cultured granulosa cells. Porcine granulosa cells were cultured for 48 h with or without LMCM in the absence or presence of 100 ng/ml LH, FSH or prolactin. Progesterone and estradiol concentrations were measured by radioimmunoassay. Granulosa cells were a...

Modulating steroid hormone levels is a curative and preventive measure for Cushing's syndrome, aldosteronism, and various stress-triggered symptoms. Polyphenols have been reported to inhibit steroidogenic enzymes such as 3β-hydroxysteroid dehydrogenase (3β-HSD) and aromatase. However, evidence for their inhibitory effects is fragmentary because it has been determined in studies with small group...

OBJECTIVE To evaluate the placental activity of steroid sulfatase (STS), 3β-hydroxysteroid dehydrogenase type 1 (3β-HSD-1) and P450 aromatase (P450arom) in polycystic ovarian syndrome (PCOS) compared to normal pregnant women. DESIGN Twenty pregnant women with PCOS and 30 control pregnant women who delivered at term were studied. Samples of placental tissue and cord blood were obtained after d...

3β-hydroxysteroid dehydrogenase II (3β-HSD) deficiency represents a rare CAH variant. Newborns affected with its classic form have salt wasting in early infancy and genital ambiguity in both sexes. High levels of 17-hydroxypregnenolone (Δ517OHP) are characteristic, but extra-adrenal conversion to 17-hydroxyprogesterone (17OHP) may lead to positive results on newborn screening tests.
