摘要: Objective:The purpose of the study is to investigate the ef ects of up-regulation of Raf kinase inhibitor protein (RKlP) on the chemosensitivity of cervical cancer Hela cells. Methods:Eukaryotic expression plasmid pcDNA3.1(+)-ssRKIP containing human overal length RKIPcDNA was transfected into cervical cancer Hela cellby lipofectin assay, establishing a stable cellline containing a target gene by G418. Expression of RKIP in Hela cells was measured by Western blot analysis. After treatment with cisplatin of dif erent concentrations and intervals of time, the ef ect of RKIP on the proliferation of Hela cells was evaluated by MTT method. The flow cytometry was used to investigate whether the RKIP could inhibit apoptosis in Hela cells induced by cisplatin. Results:The expression of RKIP in Hela cells transfected with pcDNA3.1-ssRKIP was increased obviously. After dif erent concentrations of cisplatin treatment cells for 24, 48 and 72 h, the growth inhibition rate in Hela cells transfected with pcDNA3.1-ssRKIP was significantly higher than in control cells (P<0.05). With 5μg/mL cisplatin treatment for 24 h, pcDNA3.1-ssRKIP-transfected Hela cells had an obviously higher percentage of apoptosis (23.2 ± 0.24)%than non-transfected cells (12.4 ± 0.31)%and empty vector-transfected cells (13.4 ± 0.47)%. Without treatment of cisplatin, the percentage of apoptosis for Hela cells transfected with pcDNA3.1-ssRKIP was (5.7 ± 0.12)%, which was stil higher than those of the non-transfected cells (2.9 ± 0.21)%and empty vector-transfected cells (3 ± 0.08)%. Conclusion:Higher expres-sion of RKIP gene can improve chemosensitivitv of cervical cancer Hela cells to cisplatin.
