目的 研究前列腺癌细胞中miR-221的表达情况及其对癌细胞增殖的影响。方法 运用实时荧光定量PCR(qRT-PCR)检测miR-221在前列腺正常细胞株与前列腺癌细胞株中表达的差异情况,利用细胞转染构建miR-221过表达LNCaP和DU145细胞株,再通过CCK8细胞增殖实验检测细胞增殖情况的变化。结果 qRT-PCR检测细胞株发现miR-221在PC3、LNCaP和DU145三种前列腺癌细胞株中表达量均比前列腺正常细胞株PrEC低 (F=254.197,P<0.001),其中两两比较差异也均有统计学意义。细胞转染技术构建的miR-221过表达LNCaP和DU145细胞株,经qRT-PCR结果显示,miR-221在LNCaP和DU145细胞株中的表达水平明显升高(LNCaP,倍数变化=2.24,t=3.46,P<0.01;Du145,倍数变化=2.24,t=4.29,P<0.01)。细胞增殖实验结果显示,过表达了miR-221的LNCaP(P<0.001)和DU145(P<0.001)细胞生长速度慢于对照组。结论 实验证明miR-221表达过度能减慢前列腺癌细胞的增殖,miR-221有可能成为前列腺肿瘤治疗的生物学标志物。

Objective To investigate miR-221 expression in prostate cancer cells and its influence on prostate cancer cell proliferation. Methods miR-221 expressions in prostate normal cell lines and cancer cell lines were measured by qRT-PCR. Overexpression of the miR-221 in LNCaP and DU145 cell lines used by cell transfection. Effects of the depletion on cell proliferation were assessed in vitro with CCK8. Results qRT-PCR showed miR-221 was lower expressed in PC3, LNCaP and DU145 than in PrEC(F=254.197, P<0.001), in which pairwise comparison also had significant differences. qRT-PCR showed miR-221 expression rose significantly in LNCaP and DU145 cell lines whose miR-221 was overexpression with cell transfection(LNCaP, Fold Change=2.24,t=3.46,P<0.001;Du145, Fold Change=2.24,t=4.29,P<0.001). Cell proliferation assay showed that growth of LNCaP(P<0.001) and DU145(P<0.001) cells whose miR-221 was overexpression was slower than the control group. Conclusion This study demonstrates miR-221 overexpression can inhibited the proliferation of prostate cancer cells for the first time, it also suggests that miR-221 has the potential to serve as a biomarker for PCa therapy.
