摘要
反义c-erbB_(2)以剂量相关方式抑制黄体细胞hCG诱导的孕酮的产生,同时使c-erbB_(2)蛋白染色阳性的黄体细胞百分数下降,无义tat ODN没有相应的作用。10~(-4) mol/L的二丁酰cAMP能明显反转反义c-erbB_(2) ODN对孕酮产生和c-erbB_(2)表达的抑制作用,钙离子通道阻断剂维拉帕米和蛋白抑制剂CYX对此抑制作用有协同效应。

Abstract
Antisense c-erbB_(2) ODN inhibited hCG-induced progesterone production in a dose-dependent manner; and the percentage of luteal cells stained for c-erbB_(2) protein was decreased. But nonsense tat ODN had no similar effect. The effect of dbcAMP was in contrast with that of antisense c-erbB_(2) ODN, which suppressed the progesterone production and reduced the percentage of luteal cells stained for c-erbB_(2) protein. On the other hand, both verapamil and CYX enhanced the inhibition of antisense c-erbB_(2) ODN. The result of the present investigation suggests that cAMP, Ca~(2+)-dependent pathway participates in the expression of protooncogene.
