Chinese Journal of Obstetrics and Gynecology.2010;45(9):691-698. doi:10.3760/cma.j.issn.0529-567x.2010.09.012

Objective To study the mechanism of chemotherapy resistance caused by interleukin-6 (IL-6) in ovarian cancer cells and its related signal pathways. Methods Ovarian cancer cell lines A2780(IL-6 receptor positive, while non-IL-6-expressing and cisplatin/paclitaxel-responsive) and SKOV3 cell lines( overexpressing of IL-6 receptor and IL-6 and cisplatin/paclitaxel-resistant) were suitable models for this study. The effect of exogenous (a short period of treatment with recombination IL-6) and endogenous IL-6(by transfecting with plasmid encoding for sense IL-6 ) in A2780 cells or deleting of endogenous IL-6expression in SKOV3 cells (by transfecting with plasmid encoding for antisense IL-6) on the sensitivity to cisplatin and paclitaxel was investigated. Meanwhile, the mechanism of chemotherapy resistance caused by IL-6 in ovarian cancer cells and its related signal pathways were also analyzed. Results We found that both exogenous and endogenous IL-6 induce cisplatin and paclitaxel resistance in non-IL-6-expressing A2780 cells (the resistance multiple to cisplatin and paclitaxel was: exogenous, 6. 25 and 7.31; endogenous, 7. 13 -8. 34 and 7. 61 - 10. 70), while deleting of endogenous IL-6 expression in IL-6-overexpressing SKOV3 cells promotes its sensitivity to anticancer drugs ( the resistance multiple to cisplatin and paclitaxel was 0. 15 and 0. 10, 0. 10 and 0. 08). IL-6 significantly up-regulated the expression levels of mRNA and protein of drug resistance-associated genes, MDR1 and GST-π, and apoptosis-inhibiting genes, bcl-2, bcl-xL and XIAP in a dose-dependent manner in A2780 cells. In accordance with this finding, the mRNA and protein levels of MDR1 and GST-π enhanced in sense IL-6-transfected A2780 cells, and reduced in antisense IL-6-transfected SKOV3 cells compared with the corresponding parental and control vector-transfected cells, which had no difference. It was found that PD98059 [ mitogen-activated protein kinase-extracellular signalregulated kinase (MEK) inhibitor ] and wortmannin [ phosphatidylinositol 3-kinase (PI3K) inhibitor ]significantly antagonized IL-6-induced phosphorylation of extracellular signal-regulated kinase ( ERK ) and protein kinase B (Akt), respectively, and both of them blocked IL-6-induced cisplatin and paclitaxel resistance and the inhibitory effects of PD98059 and wortmannin were dependent on its concentration.Conclusions These data suggest that IL-6-induced chemoresistance may be associated with increase of both drug resistance-associated genes ( MDR1 and GST-π) and apoptosis-inhibiting genes ( bcl-2, bcl-xL and XIAP), and activation of MEK/ERK and PL3K/Akt. Therefore, modulation of IL-6 expression or its related signaling pathway may be a promising strategy of treatment for drug-resistant ovarian cancer.

Chinese Journal of Obstetrics and Gynecology.2010;45(9):686-690. doi:10.3760/cma.j.issn.0529-567x.2010.09.011

Objective To explore the regulation of Bub1 mRNA expression in endometrial carcinoma cells by estrogen and paclitaxel. Methods The high differentiated endometrial adenocarcinoma cells ( Ishikawa cell line) were cultured in DMED/F12 supplemented with 10% fetal bovine serum(FBS) or phenol red-free DMED/F12 supplemented with 5% dextran-charcoal FBS (dcFBS). Firstly, the cells were stimulated by 10 nmol/L estradiol (17β-E2 ) or no hormonal stimulation as control group, and the cell proliferation was quantified at 24, 48 and 72 hours using cell counting kit-8 (CCK-8) method. Then the cells were stimulated with different concentrations of 17β-E2 (0.1, 10, 1000 nmol/L) at different periods (5,15,30 minites and 2,4,8,12,16,24,30 hours), the expression of Bub1 mRNA was detected by real-time quantitative PCR. Ishikawa cells were cultured with non-serum DMEM/F12 to be synchronized, and then were treated with different concentrations of paclitaxel( 10,100 nmol/L) for 8 and 24 hours. While, nonsynchronized Ishikawa cells were exposed to 100 nmoL/L paclitaxel for different periods(4, 8, 16, 24,48 hours), and real-time quantitative PCR was also used to detect the expression levels of Bub1 mRNA.Data were presented as folds change relative to control group, in which values ＜ 1 were down-regulated, and those ＞ 1 were up regulated. Results The proliferation rate of cells in the presence of 17β-E2 was significantly highter than that of the control group after treated 24 hours (A value: 0. 70 ±0. 08 vs. 0. 86 ±0.10, P = 0.049). Time-dependent experiments revealed that addition of 17β-E2 could increase cell numbers during 72 hours period, while the expression level of Bub1 mRNA was decreased in Ishikawa cell.Dose-dependent experiments revealed maximal estradiol stimulation effects at 10 nmol/L( P = 0. 020). After being treated with serum-free culture, Ishikawa cells were exposed to 10 nmol/L paclitaxel for 8 and 24 hours, and the expression of Bubl mRNA decreased (0. 403 ± 0. 008 vs. 0. 775 ± 0. 144, P = 0. 251 ).Compared to the control cells, the mRNA expression levels of Bub1 in cells treated by paclitaxel for 8 hours was significantly decreased ( P = 0. 009 ), while there was not significantly decreased at 24 hours ( P =0. 396). When exposed to 100 nmol/L paclitaxel for 8 and 24 hours, the expression of Bubl mRNA was also decreased(0. 697 ±0. 017 vs. 0. 850 ±0. 004, P =0. 061 ). Compared to the control cells, Bub1 mRNA expression was also significantly decreased (P = 0. 038 and P= 0. 019, respectively). While with serum freetreatment culture, when Ishikawa cells exposed to 100 nmoL/L paclitxel for 4, 8, 16, 24 or 48 hours, the expression of Bub1 mRNA significantly increased ( 1. 127 ± 0. 105 vs. 1. 614 ± 0. 154 vs. 2. 092 ± 0. 179vs. 1. 381 ± 0. 061 vs. 1. 519 ± 0. 182, P = 0. 002 ), of which was signicantaly increased at 16 hours treatment. Conclusion Bub1 exrpession could be regulated by estradiol and paclitaxel, in which deregulated Bubl expression may contribute to chemotherapeutic efficacy of paclitaxel.

Objective To study the effect of urodynamic factors on the urinary retention of the patients with cervical cancer received radical hysterectomy. Methods Seventy-two patients with cervical cancer Ininternational Federation of Gynecology and Obstetrics (FIGO) stage Ⅰ bl to Ⅱ a hospitalized in Fujian Provincial Maternity and Child Health Hospital between June 2006 and August 2009, who were not found any abnormal representation of urodynamics before the operation, were divided into the group with urinary retention and the group without urinary retention based on whether urinary retention after the operation. All patients were detected by urodynamic examination following radical hysterectomy. Data obtained from urodynamic examination were analysed by logistic regression to evaluate the influence of urodynamic factors on the urinary retention postoperation. Results Twenty-one patients out of all were found with urinary retention after the operation , the incidence rate of urinary retention was 29%. The first sensation after operation in both groups were increased significantly than those before operation[ ( 171 ±61 )ml vs.(126 ±28)ml, (134±39)ml vs. (119 ± 17)ml,all P＜0.05], while the maximum volume[ (337 ±66) and (300 ±66)ml, respectively], the compliance[ (31 ±25) and (29 ± 18) ml/cm H2O (1 cm H2O =0. 098 kPa), respectively], the maximum flow rate[ (10 ±4) and (12 ±5) ml/s, respectively] and the pressure at the maximum flow rate [ (27 ±9) and (32 ±8) cm H2O, respectively] were decreased obviously after radical hysterectomy in both the group with urinary retention and the group without urinary retention ( all P ＜0.05), compared with the corresponding value before the operation. The urodynamic changes in urinary retention group was much more severe than those in group without urinary retention ( P ＜ 0. 05 ). The single factor analysis results showed that bladder destusor dysfunction ( OR = 8. 20, 95% CI: 2.62 - 25. 66, P ＜0. 01 ) and lack of sensation ( OR = 6. 90, 95% CI: 1.95 - 24. 43, P ＜ 0. 01 ) were relevant to the urinary retention post-operation. While there were not relationship was found between low compliance bladder( OR =1.99, 95% CI:0. 70 - 5.63, P = 0. 195 ), detrusor overactivity ( OR = 2. 51, 95% CI: 0. 73 - 8.67, P =0. 144), bladder outlet obstruction ( OR = 3.77, 95% CI: 0. 76 - 18. 57, P = 0. 104 ) or dyssynergia of urethral external sphincter( OR =2. 67, 95% CI:0. 49- 14. 45, P =0. 255 ) and urinary retention following the operation. There were an antagonistic effects ( OR = 7.60, 95% CI: 1.43 - 40. 39, P = 0. 017 ) of detrusor overactivity and bladder destrusor dysfunction on urinary retention. The multiple factors analysis results revealed that bladder destusor dysfunction( OR = 7.01, P ＜ 0. 01 ) and lack of sensation( OR = 5.45, P =0. 018)were the independent risk factors influening on the urinary retention post-operation. Conclusions There are obvious urodynamic change in cervical cancer patients following radical hysterectomy. Bladder destrusor dysfunction and lack of sensation are the independent urodynamic risk factors influencing on urinary retention following radical hysterectomy, while detrusor over activity may be a protective effect on bladder destrusor dysfunction post-operation in some degree. Urodynamic test is important for analysis and treatment of urinary retention following radical hysterectomy.
