RIT1 and hepatocellular carcinoma: To explore the underlying molecular mechanism by which RIT1 regulates mitosis in HCC, we transfected Myc-tagged RIT1 plasmids into Huh7, Hep3B, and HCC-LY10 cells and detected RIT1 distribution during different cell cycle stages by immunofluorescence staining with an anti-Myc antibody.
