Synergistic Expression of Ad4BP/SF-1 and Cytochrome P-450 Aromatase (Ovarian Type) in the Ovary of Nile Tilapia, Oreochromis niloticus, During Vitellogenesis Suggests Transcriptional Interaction1

Abstract excerpt

Involvement of Ad4BP/SF-1 in the ovarian cytochrome P-450 aromatase (oP450arom) gene expression was investigated using ovarian follicles of the Nile tilapia, possessing an average 14-day spawning cycle. The promoter region (5' flanking region) of oP450arom gene cloned from tilapia contains two Ad4 binding sites. Subsequently, a cDNA encoding Ad4BP/SF-1 was cloned from the ovarian follicles. It is expressed in...
