In order to understand the physiological roles of vasoactive intestinal contractor (VIC)/endothelin-2 (ET-2), we examined the expression of this peptide by specific reverse transcriptase polymerase chain reaction (RT-PCR) analysis and found that PC12 rat pheochromocytoma cells express the VIC gene. The 5'-flanking 1.0 kilo base pair (kb) region of the mouse VIC gene is sufficient to express a secreted alkaline phosphatase (SEAP) reporter gene in transiently transfected PC12 cells. The 1.0 kb promoter region may contain cis-acting elements that determine the rate of the VIC gene transcription in PC12 cells.
为了了解血管活性肠收缩肽(VIC)/内皮素-2(ET-2)的生理作用,我们通过特异性逆转录聚合酶链反应(RT-PCR)分析检测了该肽的表达,发现PC12大鼠嗜铬细胞瘤细胞表达VIC基因。小鼠VIC基因5'侧翼1.0千碱基对(kb)区域足以在瞬时转染的PC12细胞中表达分泌性碱性磷酸酶(SEAP)报告基因。1.0 kb的启动子区域可能包含决定PC12细胞中VIC基因转录速率的顺式作用元件。
