【摘要】:目的:探討慢病毒干擾載體沉默Yes-相關(guān)蛋白(Yes-associatedprotein, YAP)對人腎癌786-0細胞增殖和凋亡的影響。 方法:體外培養(yǎng)腎癌786-0細胞,構(gòu)建針對YAP基因的shRNA慢病毒干擾載體并轉(zhuǎn)染786-0細胞。RT-PCR和Western blot分別檢測干擾786-0細胞前后YAP及其下游轉(zhuǎn)錄因子TEAD1mRNA及蛋白的表達情況;CCK-8(cell counting kit-8)法檢測沉默YAP后細胞增殖的改變;流式細胞儀(flow cytometry, FCM)檢測細胞凋亡和周期的變化情況。 結(jié)果:構(gòu)建了3條針對YAP基因的YAP-shRNA慢病毒干擾載體和1條陰性對照慢病毒載體并成功轉(zhuǎn)染786-0細胞;YAP-shRNA慢病毒干擾載體轉(zhuǎn)染96小時后,可顯著下調(diào)786-0細胞YAP mRNA及蛋白表達水平(P=0.000),并且TEAD1mRNA及蛋白表達水平也明顯下降(P=0.000);與空白對照組和陰性對照組細胞相比,轉(zhuǎn)染組細胞增殖明顯抑制,細胞凋亡顯著增加(P=0.000),細胞周期紊亂,,G1期細胞明顯增加,S期細胞明顯降低(P=0.000)。 結(jié)論: YAP-shRNA慢病毒干擾載體能有效抑制YAP基因在786-0細胞中表達,進而抑制細胞增殖并促進細胞凋亡。
[Abstract]:Aim: to investigate the effect of lentivirus interference vector silencing Yes- associated protein (Yes-associatedprotein, YAP) on proliferation and apoptosis of human renal cell carcinoma 786 cells. Methods: 786 cells of renal cell carcinoma were cultured in vitro. The shRNA lentivirus interference vector targeting YAP gene was constructed and transfected into 786 / 0 cells. The expression of YAP and its downstream transcription factor TEAD1mRNA and protein were detected by RT-PCR and Western blot before and after interfering with 786 / 0 cells, respectively. the expression of YAP and its downstream transcription factor TEAD1mRNA and protein were detected before and after interference. CCK-8 (cell counting kit-8) was used to detect the changes of cell proliferation after silencing YAP, and flow cytometry (flow cytometry, FCM) was used to detect the changes of apoptosis and cycle. Results: three YAP-shRNA lentivirus interference vectors targeting YAP gene and one negative control lentivirus vector were constructed and successfully transformed into 786 cells. After 96 hours of transfection with YAP-shRNA lentivirus interference vector, the expression of YAP mRNA and protein in 786 / 0 cells was significantly down-regulated (P 鈮
