Increased cholangiocyte growth is critical for the maintenance of biliary mass during liver injury by bile duct ligation (BDL). Circulating levels of testosterone decline following castration and during cholestasis. Cholangiocytes secrete sex hormones sustaining cholangiocyte growth by autocrine mechanisms. We tested the hypothesis that testosterone is an autocrine trophic factor stimulating bi...
1. 11 beta-Hydroxysteroid dehydrogenase converts cortisol to inactive cortisone in man. In distal renal tubules, this inactivation protects mineralocorticoid receptors from cortisol. Congenital 11 beta-hydroxysteroid dehydrogenase deficiency and inhibition of 11 beta-hydroxysteroid dehydrogenase by liquorice or carbenoxolone result in cortisol-dependent hypokalaemia and hypertension. 2. 11 beta...
Obesity is a complex metabolic disease, which causes serious impairment to the health of people. This study aimed to determine the influence of different-doses of soy isoflavones (SIF) on testicular morphology, testosterone levels and the expression of genes and proteins related to testosterone synthesis in diet-induced obesity (DIO) male rats. We used high-fat diet (HFD) to establish a DIO mal...
The Leydig cells of the testis have the capacity to biosynthesize testosterone from cholesterol. Testosterone and its metabolically activated product dihydrotestosterone are critical for the development of male reproductive system and spermatogenesis. At least four steroidogenic enzymes are involved in testosterone biosynthesis: Cholesterol side chain cleavage enzyme (CYP11A1) for the conversio...
Background/Aims. Genetic variants that affect estrogen activity may influence the risk of Alzheimer's disease (AD). In women with Down syndrome, we examined the relation of polymorphisms in hydroxysteroid-17beta-dehydrogenase (HSD17B1) to age at onset and risk of AD. HSD17B1 encodes the enzyme 17β-hydroxysteroid dehydrogenase (HSD1), which catalyzes the conversion of estrone to estradiol. Metho...
