26271515 Current level of understanding on tissue-specific and hormone-induced regulation of STAR expression and steroidogenesis, and insights into a number of cholesterol and/or steroid coupled physiological consequences.[review]
26014698 amino acid of mutant position of the novel p.E123K was highly conserved in ten different species and was predicted to have impacts on the structure and function of StAR protein by the PolyPhen-2 prediction software
26001835 activins A, B and AB down-regulate StAR expression and decrease progesterone production in human granulosa cells, likely via an ALK4-mediated SMAD2/SMAD4-dependent pathway.
25002576 Mutagenesis confirmed that Arg(312) and Arg(313) are crucial for this mode of regulation, and novel interactions with the START domain
25001622 Hypoxia in pulmonary artery endothelial cells results in upregulation of STAR protein.
24422629 StAR proteolysis is executed by at least 2 mitochondrial proteases, the matrix LON protease and the inner membrane complexes of the metalloproteases AFG3L2 and AFG3L2:SPG7/paraplegin.
24140593 BMP15 down-regulates StAR expression and decreases progesterone production in human granulosa cells, likely via ALK3-mediated SMAD1/5/8 signaling.
24053410 Cholesterol-mediated conformational changes in StAR are essential for steroidogenesis.
23920000 The novel mutation p.Trp147Arg of the steroidogenic acute regulatory protein causes classic lipoid congenital adrenal hyperplasia with adrenal insufficiency and 46,XY disorder of sex development.
23825130 Expression of StAR and P45011beta (cytochrome P450 family 11 subfamily B polypeptide 1) is down-regulated in adrenocortical cells and neurons under oxidative stress by ALADIN (triple A syndrome protein, human) knockdown.
