Additional file 6: of LncRNA CASC9 interacts with CPSF3 to regulate TGF-β signaling in colorectal cancer LuoKaili GengJingwen ZhangQinkai XuYesha ZhouXunzhu HuangZheng ShiKe-Qing PanChenwei WuJianmin 2019 Figure S5. Knockdown or overexpression efficiency of CASC9 in stable CRC cell lines. (A) RT-qPCR analysis of relative CASC9 levels in HCT-116 and SW620 cells transduced with shCASC9 lentivirus (shC9–1 and shC9–2) or control lentivirus (shCON). (B) RT-qPCR analysis of relative CASC9 levels in HCT-116 and SW480 cells transduced with CASC9–202-overexpressing lentivirus (LV-C9–202) or control lentivirus (LEV). The data are presented as mean ± s.d. *P < 0.05, **P < 0.01, ****P < 0.0001 by Student’s t-test. (TIF 438 kb)
