沉默Smo基因?qū)θ藢m頸癌HeLa細(xì)胞活力及凋亡的影響
[Abstract]:Aim: to study the effect of RNA interference technique on the viability and apoptosis of cervical cancer He La cells by silencing Smoothened (Smo) gene. Methods: Smo shRNA was used to transfect cervical cancer He La cells, RT-PCR and Western blot techniques were used to detect the mRNA and protein expression of Smo and transcription factor Gli1 in He La cells, and MTT colorimetric assay was used to detect the cell growth after Smo silencing. The effect of Smo shRNA on cell cycle and apoptosis was detected by flow cytometry. Results: compared with the control group, the expression of mRNA and protein in Smo and Gli1 decreased significantly 72 h after transfection with, Smo shRNA (P0.05) the activity of, He La cells was significantly decreased after). Smo gene silencing, and the cells were significantly blocked in G0/G1 phase. Apoptosis rate increased significantly. Conclusion: silencing Smo gene can effectively inhibit the growth and induce apoptosis of human cervical cancer He La cells.
