Objective To investigate the effect of estrogen( E2) ,progesterone( P4) , and paclitaxel ( taxol) on the growth of primary human ovarian cancer cells in vitro and the expression of Drosha. Methods Human ovarian cancer cells were treated with estrogen, progesterone or in combination with paclitaxel in vitro. The inhibition rate of ovarian cancer cells was assessed by methyl thiazolyl tetrazolium ( MTT) assay. Apoptosis rate and cell cycle were determined by FACS analysis.The relative abundence of Drosha expression was detected by real?time quantitative PCR ( qRT?PCR) and Western blotting. Results The inhibition rate of the estrogen group, progesterone group, paclitaxel group, E2 (+) Taxol group, P4 (+) Taxol group was (31.53±8.21)%, ( 25. 22 ± 15. 50)%, ( 46. 71 ± 4. 25)%, ( 69. 46 ± 3. 71)%, and ( 47. 35 ± 39. 02)%, respectively, significantly higher than that of the control group (0%, P<0.05 for all). Relative to the ER (-) in ovarian cancer cells,Drosha mRNA expression level of estrogen group, progesterone group, paclitaxel group, E2(+) Taxol group,and P4(+)Taxol group was 1.62±0.10,1.60±0.10,1.75±0.16,1.95±0.20, and 1.53±0.06, respectively, significantly higher than that of the control group (1.00,P<0.05 for all). Relative to the ER (+) in ovarian cancer cells,the Drosha mRNA expression level of estrogen group, progesterone group, paclitaxel group, E2(+)taxol group,and P4(+)Taxol group was 1.03±0.14,1.60±0.09,1.75±0.16, 1.60±0.10, 1.53±0.06, respectively except estrogen group, significantly higher than that of the control group ( 1.00, P<0.05) . Relative to the ER (-) in ovarian cancer cells, the Drosha protein expression levels of the control group, estrogen group, progesterone group, paclitaxel group, E2(+) taxol group, and P4(+) Taxol group were 0.25±0.05,0.87±0.30,0.85±0.38,1.30±0.21,1.75±0.83,1.62±0.82, respectively, with a significant difference between the experimental groups and the control group (P<0.05). Relative to the ER (+) ovarian cancer cells, the Drosha protein expression levels in the estrogen group, progesterone group, paclitaxel group, E2(+) taxol group, and P4(+) taxol group,were 0.28±0.16,0.85±0.38,1.30±0.21,0.94± 0.18, and 1.62±0.82, respectively except estrogen group, significantly higher than that of the control group (0.25±0.05, P<0.05 for all). Conclusions Estrogen and progesterone in combination with paclitaxel can inhibit the growth of human ovarian cancer cells in vitro, and affect the cell apoptosis rate. Estrogen and taxol can alter the cell cycle. Estrogen and progesterone combined with paclitaxel show tumor suppressing or sensitizing effect through upregulated Drosha expression, and are associated with the estrogen receptor expression.
