目的 探讨Meis1在人子宫内膜细胞中的表达及其受雌、孕激素调控的规律。方法 通过免疫细胞化学和western blot的方法检测雌、孕激素对体外培养的在子宫内膜基质细胞(ESC)及Ishikawa细胞中Meis1的表达及调控。结果 Meis1在ESC和Ishikawa细胞均有表达,且均表达于细胞核中;在ESC中,E2、P4和 E2+P4三组中Meis1平均蛋白表达水平均高于对照组(P<0.05)。Meis1在E2、P4和 E2+P4组之间的表达水平亦差异有统计学意义(P<0.05),表达强度E2+P4组>P4组>E2组;在Ishikawa细胞中,E2、P4和 E2+P4使Meis1表达增强,表达强度P4组>E2+P4组>E2组,但与对照组比较无差异(P>0.05),E2、P4和 E2+P4各组间亦无差异(P>0.05)。结论 转录因子Meis1在ESC和Ishikawa细胞中受到雌、孕激素的调控,可能在子宫内膜容受性分子网络的构建中发挥着重要的作用。
Objective To investegate the expression and regulation discipline of Meis1 in human ESC and Ishikawa cells in vitro by estrogen and progesterone stimuli. Methods Immunocytochemistry and western blot were used to detect the expression and regulation discipline of Meis1 in human normal endometrial cells. Results Meis1 expressed both in endometrial stromal cells (ESC) and in ishikawa cells, and both situ in nucleus. In ESC, the expression of Meis1 was up-regulated by E2/P4 and E2+P4, and the up-regulated effect may be superposition by E2+P4, the differences between the groups were statistically difference(P<0.05). In Ishikawa cells, western blot showed that the expression of Meis1 was up-regulated by E2/P4 and E2+P4. The differences weren't statistically significant when compared with the control group or between themselves(P>0.05). Conclusion The expression of transcription factor Meis1 is regularly regulated by estrogen and progesterone, which may be a key role during the formation of endometrial receptivity molecular network.
