Regulation of Steroidogenesis and Steroidogenic Acute Regulatory Protein in R2C Cells by DAX-1 (Dosage-Sensitive Sex Reversal, Adrenal Hypoplasia Congenita, Critical Region on the X Chromosome, Gene-1)

Abstract excerpt

In the present study, steroidogenesis in two different Leydig tumor cell lines was compared. One, the MA-10 mouse tumor cell line, produces steroids and the steroidogenic acute regulatory (StAR) protein only when stimulated by trophic hormones and cAMP analogs. The other, the R2C rat tumor cell line, produces steroids and the StAR protein constitutively without stimulation. We observed that high levels of DAX-1...
