MARCHF1 and hepatocellular carcinoma: To further explore the biological function of MARCH1, we transiently depleted the MARCH1 expression in the HCC cells using two different effective sequences of siRNA interference (MARCH1 siRNA‐1 and MARCH1 siRNA‐2) and using the blank control (transfected negative siRNA) and non‐target siRNA (non‐transfected) groups as the negative controls (Figure 1C,D).
