【 摘 要 】
The possible role of cyclic AMP (cAMP) in the regulation of the vasopressin (VP) gene was tested in two cellular expression systems: one cell line with endogenous VP expression and the other which was transiently with a VP promoter-luciferase fusion gene. 8, Bromo-cAMP stimulated the VP mRNA content about 4-fold in the human VP-expressing small cell lung carcinoma cell line GLC-8. The luciferase activity in P19 embryonal carcinoma cells which were transiently transfected with − 174 to +44 of the 5'-flanking region of the human VP gene linked to the firefly luciferase gene, was stimulated about 2-fold by the cAMP analogue. The results indicate that cAMP plays a role in the upregulation of the VP gene and hence point to several putative nucleotide motives in the promoter functionally conferring this response.
