目的探讨罗哌卡因对骨肉瘤细胞增殖和凋亡的影响及作用机制。方法体外培养骨肉瘤细胞 MG63,分为对照组、低剂量罗哌卡因组、中剂量罗哌卡因组、高剂量罗哌卡因组、 anti?miR?NC组、 anti?miR?199b?5p组、中剂量罗哌卡因 +miR?199b?5p组和中剂量罗哌卡因 +miR?NC组。四甲基偶氮唑盐微量酶反应比色法(MTT法)检测细胞增殖,流式细胞仪检测细胞凋亡,白质印迹法(Western Blot)检测细胞中细胞周期蛋白 D1(CyclinD1)、 P21、B细胞淋巴瘤 /白血病 ?2(Bcl?2)、 Bcl?2相关 X蛋白蛋(Bax)表达水平,实时荧光定量逆转录 PCR(RT?qPCR)检测细胞中 miR?199b?5p表达水平。结果与对照组比较,低剂量罗哌卡因组、中剂量罗哌卡因组、高剂量罗哌卡因组 MG63细胞增殖能力[(0.88±0.08)、(0.49±0.05)、(0.34±0.03)比(0.92±0.09)]、 Cyclin D1蛋白[(0.85±0.08)、(0.66±0.06)、(0.41±0.04)比(0.95±0.09)]表达降低(P<0.05),而 P21[(0.18±0.02)、(0.37±0.04)、(0.71±0.07)比(0.14±0.01)]蛋白表达升高(P<0.05)中剂量罗哌卡因组 Bcl?2蛋白[(0.20±0.02)比(0.76±0.07)]及 miR?199b?5p[(0.13±0.01)比(0.82±0.08)]的表达降低(P<0.05),而,MG63细胞凋亡率[(23.51±2.42)%比(7.66±0.75)%]和 Bax蛋白[(0.89±0.09)比(0.28±0.03)]表达升高(P<0.05)。与 anti?miR?NC组比较, anti?miR?199b?5p组 MG63细胞增殖能力[(0.64±0.06)比(0.98±0.09)]及 Cyclin D1蛋白[(0.40±0.04)比(0.95±0.09)]和 Bcl?2蛋白[(0.36±0.03)比(0.76±0.07)]的表达降低(P<0.05),而 MG63细胞凋亡率[(19.56±1.58)%比(7.66±0.75)%]及 P21[(0.53±0.05)比(0.14±0.01)]和 Bax[(0.71±0.07)比(0.28±0.03)]的蛋白表达升高(P<0.05)。与中剂量罗哌卡因 +miR?NC组比较,中剂量罗哌卡因 +miR?199b?5p组 MG63细胞增殖能力[(0.58±0.06)比(0.36±0.03)]及 Cyclin D1蛋白[(0.71±0.07)比(0.40±0.04)]和 Bcl?2蛋白[(0.53±0.05)比(0.21±0.02)]的表达升高(P<0.05),而 MG63细胞凋亡率[(12.68±1.23)%比(23.35±2.34)%]及 P21[(0.37±0.03)比(0.72±0.07)]和 Bax[(0.57±0.06)比(0.88±0.09)]的蛋白表达降低(P<0.05)。结论罗哌卡因可能通过下调 miR?199b?5p降低了骨肉瘤细胞的增殖,并促进了其凋亡。 |
