Steroidogenic factor-1 (SF-1, NR5A1) and human disease
Steroidogenic factor-1 (SF-1, Ad4BP, encoded by NR5A1) is a key regulator of adrenal and reproductive development and function. Based upon the features found in Nr5a1 null mice, initial attempts to identify SF-1 changes in humans focused on those rare individuals with primary adrenal failure, a 46,XY karyotype, complete gonadal dysgenesis and Müllerian structures. Although alterations affecting...
متن کاملThe role of SF-1/Ad4BP in the control of the bovine gene for the steroidogenic acute regulatory (StAR) protein.
The bovine gene for the steroidogenic acute regulatory protein (StAR) was cloned and sequenced, including 2 kb of the upstream control region of the gene. The gene comprises seven exons arranged similarly to those of the human and mouse gene sequences. The sequence analysis identified three cis elements corresponding to the binding motif for the transcription factor SF-1/Ad4BP, at - 100, - 240 ...
متن کاملOxysterols regulate expression of the steroidogenic acute regulatory protein.
The steroidogenic acute regulatory (StAR) protein promotes intramitochondrial delivery of cholesterol to the cholesterol side-chain cleavage system, which catalyzes the first enzymatic step in all steroid synthesis. Intriguingly, substrate cholesterol derived from lipoprotein can upregulate StAR gene expression. Moreover, substrate oxysterols have been suggested to also play a role. To investig...
متن کاملcAMP-stimulated transcription of DGKθ requires steroidogenic factor 1 and sterol regulatory element binding protein 1.
Diacylglycerol kinase (DGK)θ is a lipid kinase that phosphorylates diacylglycerol to form phosphatidic acid (PA). We have previously shown that PA is a ligand for the nuclear receptor steroidogenic factor 1 (SF1) and that cAMP-stimulated expression of SF1 target genes requires DGKθ. In this study, we sought to investigate the role of cAMP signaling in regulating DGKθ gene expression. Real time ...
متن کاملLipoproteins regulate expression of the steroidogenic acute regulatory protein (StAR) in mouse adrenocortical cells.
The steroidogenic acute regulatory protein (StAR) is required for the movement of cholesterol from the outer to the inner mitochondrial membrane, the site of cholesterol side chain cleavage. Here we describe a novel form of regulation of StAR gene expression in steroidogenic cells. Treatment of Y-1 BS1 adrenocortical cells with either low density lipoprotein (LDL) or high density lipoprotein (H...
