Abstract:
Objective:To discuss the different expression of AQP8 in cultured normal human trophocyte and JAR cell line,and the relationship between the changed expression of the channel protein and nosogenesis of chorionic carcinoma.Methods:The human cultured normal trophocyte was primarily cultured,purified and identified.JAR cell line was cultured.The expression of AQP8 was detected in cultured normal human trophocyte and JAR cell line by immunohistochemistry immunofluorescence confocal laser and RT-PCR.Results:(1)In the control group,the limitied expression of AQP8 was observed in cultured normal human trophocyte and JAR cell line,but in the exprimental group,the rate of positive cell of AQP8 in JAR cell line were 93.27%?14.45%,much higher than that in the control group.(2)By immunofluorescence staining confocal laser imaging,it was revealed that,in the same condition and excitation intensity,AQP8 in the JAR choriocarcinoma cell lines showed positive expression of the green,while in normal trophoblast cells,no green light,but when the excitation intensity was strengthened,it may still explore AQP8 in normal human villous trophoblast cell expression(.3)The expression of AQP8mRNA was detected in both cultured normal human trophocyte and JAR cell line.The OD value(0.98?0.35)of AQP8 in the experimental group was significantly higher than that(0.32?0.04)in the control group.Conclusion:Abnormal overexpression of AQP8 will destroy the external water and electrolyte balance of trophoblast cells,which might be one of the reasons for the occurrence of choriocarcinoma.
