CFL1 and hepatocellular carcinoma: Moreover, because MHCC‐97L cells show much higher IC50 value of sorafenib (≈23.7 × 10−6m) than other types of HCC cells, we used the one third of this IC50 value (≈8 × 10−6m) to investigate the influence of CFL1 silencing on the sorafenib sensitivity of HCC cells.
