【 摘 要 】

References(25)Cited-By(3)This study examined the uterine oxytocin- (OTR) and estrogen- (ER) receptor mRNA levels during and after pseudopregnancy (PSP) in rats. An increased OTR mRNA level was observed from day 14 of PSP, and the maximal level was attained during the following proestrus. The levels of ERα mRNA were low during PSP and significantly increased during the following estrus. The level of ERβ mRNA was significantly decreased during proestrus and then returned to the values observed during days 7-14 of PSP by estrus. These results suggest i) suppression of ERα mRNA during the luteal phase and that ii) the changes in OTR, ERα and ERβ mRNA levels during proestrus and estrus following PSP are similar to those during the normal estrous cycle.
