主　　题：transgenic mice EGFP monkey 20α-HSD promoter 

摘      要：To directly assess the molecular function of the monkey 20α-hydroxysteroid dehydrogenase （20α-HSD） promoter, we generated transgenic mice （tg） expressing enhanced green fluorescent protein （EGFP） under control of this promoter. We demonstrated that prostaglandin F2α induced 20α-HSD promoter activity in CHO cells in a dose-dependent manner. Furthermore, forskolin treatment markedly reduced 20α-HSD promoter activity, and prolactin exhibited weak inhibitory activity. The transgenic mouse obtained one positive founder male. The transgene was propagated in 10 successive generations without any notable defects to the progeny. EGFP and 20α-HSD in the tg mice were colocalized in the luteal cells of the ovary during late pregnancy. Strong EGFP and 20et-HSD protein signals were also detected in the adult testis. Immtmohistochemical analysis revealed high EGFP levels in the seminiferous epithelium, whereas 20α-HSD was expressed in the seminiferous tubules. Our data suggest that the ovaries in monkey and mouse exhibit similar expression patterns of 20α-HSD during pregnancy. However, the expression pattern of EGFP in tg mice testis slightly differed from that of the endogenous 20α-HSD. Further investigation is required to elucidate the functional mechanisms underlying regulation of the monkey 20α-HSD promoter in the tg mice.
