Nonclassic lipoid congenital adrenal hyperplasia masquerading as familial glucocorticoid deficiency.
CONTEXT Familial glucocorticoid deficiency (FGD) is an autosomal recessive disorder resulting from resistance to the action of ACTH on the adrenal cortex. Affected individuals are deficient in cortisol and, if untreated, are likely to succumb to hypoglycemia and/or overwhelming infection. Mutations of the ACTH receptor (MC2R) and the melanocortin 2 receptor accessory protein (MRAP), FGD types 1...
BACKGROUND The ubiquitous use of dibutyl phthalate (DBP), one of the most widely used plasticizers, results in extensive exposure to humans and the environment. DBP and its major metabolite, monobutyl phthalate (MBP), may alter steroid biosynthesis and their exposure may lead to damage to male reproductive function. Low-doses of DBP/MBP may result in increased steroidogenesis in vitro and in vi...
BACKGROUND The orphan nuclear receptor NR5A1 (steroidogenic factor-1, SF-1) is a master regulator of tissue-specific gene expression in reproductive and steroidogenic tissues. Two activating functions, AF-1 and AF-2, have been described to function in a cooperative manner to recruit transcriptional coactivators to the promoter regions of NR5A1-controlled genes. METHODS The role of the NR5A1 a...
Cancer is one of the major causes death in developed countries and current therapies are based on surgery, chemotherapeutic agents, radiation. To overcome side effects induced by chemo- radiotherapy, recent decades, targeted have been proposed second even first lines. Targeted drugs act essential pathways involved tumor induction, progression, metastasis, basically all hallmark cancers. Among e...
It has previously been shown that omission of extracellular chloride ions during culture of rat Leydig cells markedly enhances LH-stimulated steroidogenesis. In the present study, the mechanisms of the effect of chloride omission on (Bu)2cAMP-stimulated steroidogenesis in MA-10 mouse Leydig tumor cells have been investigated. It was found that chloride omission enhanced progesterone production ...
ANG II and potassium are known to increase steroidogenic acute regulatory protein (StAR) levels. However, a corresponding increase in StAR mRNA levels has so far been observed only in response to ANG II. We therefore studied the regulation of adrenal StAR mRNA expression in the context of dietary potassium-stimulated aldosterone production. Wistar-Kyoto rats (WKY) and spontaneously hypertensive...
