Abstract
To localize the regulatory elements in the human follicle-stimulating hormone receptor (FSH-R) promoter/enhancer and to determine the role of upstream stimulatingfactors (USFs) in these elements, we transiently transfected constructs of FSH-R promoter/enhancer in pGL3 luciferase reporter plasmids into Chinese hamster ovary cells and the activities were determined by measuring luciferase luminescence of the cell lysates. The 5'-flanking regions of the human FSH-R gene from nt -1485 to -1 with respect to the gene translation start site were amplified by polymerase chain reaction (PCR) and subcloned in pGL3. Deletion mutants were created using PCR or restriction enzyme digestion. Mutation in the E-box sequence from nt -124 to -119 (E-box 3), in the construct from -224 to nt -1 or in the Inr element, which encompasses the transcriptional start site at nt -99, resulted in a substantial reduction in the human FSH-R promoter/enhancer activity. Overexpression of upstream stimulating factor-1 (USF1) suppresses the activity of the human FSH-R promoter/enhancer via Inr and E-box elements. Upstream stimulating factor-2 (USF2) decreases FSH-R promoter/enhancer activity by acting on E-box 3. The results indicate that E-box 3 and the Inr element are important elements of the human FSH-R promoter/ enhancer. USF family members inhibit FSH-R gene activity by acting via these elements. USF1 and USF2 suppress human FSH-R promoter/enhancer activity by acting on E-box 3. USF1 also decreases activity by interacting with the Inr element.
