title: [Cloning of DNA complementary to mRNA for proopiomelanocortin from the bovine, rat and human hypophysis. Hormonal regulation of proopiomelanocortin mRNA in the rat hypophysis].
abstract: Cloning of DNA and complementary mRNA of bovine, rat and human proopiomelanocortin (POMC) was carried out. A structural analysis of the cloned cDNA of POMC was performed. Using restriction fragments of bovine, rat and human POMC cloned cDNA, probes for molecular hybridization based on one-chain bacteriophage M13 were made. Using the dot-hybridization technique with labeled [32P] POMC cDNA, the effect of 17 beta-estradiol and adrenalectomy on the POMC mRNA level in rat hypophysis was studied. The hormone was shown to significantly decrease the POMC mRNA content at a concentration of 4 and 8 micrograms per 100 g of body weight 4 hours after injection. Adrenalectomy caused a 2-3-fold increase in the POMC mRNA level in rat hypophysis after a period of 5-7 days. The possibility of polyhormonal control of POMC genome transcription is discussed.
