"Overlapping putative promoter regions of human PGF gene encompassing 2-1.5 kb were cloned into reporter vectors and co-transfected into trophoblast and nontrophoblast cell lines. Promoter activity generated by a 2-1.5-kb clone was significantly higher in trophoblasts than in nontrophoblasts. Selective deletion mutants showed that a clone encompassing the PGF (2-828/++34) region generated promoter activity similar to the 2-1.5-kb region in the trophoblast. However, deletion of another 131 bp from this subclone (2-698/++34) resulted in significantly less promoter activity in the trophoblast. The (2-828/2-698) region significantly enhanced activity of a minimal promoter construct in trophoblast but not in nontrophoblast cells, suggesting that this region contributes to regulating PGF transcription in the trophoblast. Site-directed mutagenesis of a glial cell missing 1 (GCM1) motif in the 131-bp region significantly decreased enhancer activity in the trophoblast. Furthermore, overexpression of GCM1 significantly increased PGF 2-1.5-kb promoter activity and PGF mRNA expression in trophoblast and nontrophoblast cells. " . . "Selventa" . . . .
