SLP-2前列腺癌 PC-3细胞增殖凋亡
摘要:
目的 探讨 SLP-2(stomatin-like protein 2)基因对人前列腺癌 PC-3细胞增殖和凋亡的影响。方法 合成和构建 SLP-2沉默和过表达载体,用 LipofectamineTM 2000分别转染 5组人前列腺癌 PC-3细胞: pcDNA3.1-SLP-2组,空质粒 pcDNA3.1组, siRNA-SLP-2组, siRNA阴性对照组以及空白对照组。采用 Q-PCR和 Western-Blot分别检测 PC-3细胞中 SLP-2的 mRNA和蛋白表达量;用细胞计数试剂盒( CCK-8)检测 PC-3细胞增殖;采用细胞线粒体膜电位 JC-1试剂盒检测 PC-3细胞的早期凋亡情况。结果 转染 pcDNA3.1-SLP-2质粒和 siRNA-SLP-2后 PC-3细胞 SLP-2基因 mRNA表达水平分别为(324.884±16.508)和( 0.195±0.016),蛋白表达水平分别为( 5.013±0.284)和( 0.296±0.011),与空白对照组相比差异均有统计学意义( P<0.05);转染 pcDNA3.1-SLP-2基因 48 h、72 h、96 h后 PC-3细胞增殖吸光度值( OD值)分别为( 0.714±0.007)、(1.103±0.018)、(1.348±0.018),均显著高于空白对照组( P<0.05)。采用 siRNA沉默 SLP-2基因 48 h、72 h、96 h后 PC-3细胞增殖率分别为( 0.571±0.004)、(0.875±0.010)、(1.044 ±0.008),均显著低于空白对照组( P<0.05);细胞凋亡结果显示,转染 pcDNA3.1-SLP-2和 siRNA-SLP-2的 PC-3细胞早期凋亡率分别为( 2.433±0.577)和( 9.197±0.602),与空白对照组( 4.993± 0.710)相比差异均有统计学意义( P<0.05)。结论 SLP-2可促进人前列腺癌 PC-3细胞的增殖,并抑制细胞的早期凋亡。
