TfR1 expression was downregulated by lentivirus-mediated shRNA. TfR1 mRNA expression was verified by real-time PCR, showing that TfR1 expression in Lenti-shTfR1 cells was significantly lower than in control cells in both SW480 (A) and SW620 (B) cell lines, ***P<0.001. (C) The downregulation of TfR1 protein expression was assessed by Western blot.
