ABSTRACT

Objective To investigate the effects of estrogen on the expression of KLK6 mRNA and protein in human ovarian cancer cell line HO8910.Methods HO8910 cells were incubated for 72 hours in two groupsthe test group with 17-?E_2 at different concentration(10~(-10)、10~(-9)、10~(-8)、10~(-7)mol/L)and the control group with Ethanol.Real-time fluorensence quantitive RT-PCR and flow cytometry were used to measured the expression of KLK6 mRNA and protein in the two groups.The cell proliferation was measured by 3-(4,5-dimethylthiazol-z-yl)-2,5-dipheny tetrazolium blue(MTT)calorimetric assay,while the cell cycle was determined by flow cytometry.Results The expression ofKLK6 mRNA(3.83?0.41、4.14? 0.49、6.26?0.38、7.28?1.82)and protein(10.62?0.35,10.89?0.12、11.88?0.28、12.07?0.15) in the test group of H08910 cells(10~(-10)10~(-9)10~(-8)10~(-7)mol/L)was higher than that in the ethanol control group(P
