Effect of RGDfC-Se@siDCBLD2 on the DCBLD2 expression and cell viability in HCT-116 cells. a The mRNA level of DCBLD2 in HCT-116 cells treated with RGDfC-Se@siDCBLD2 or RGDfC-Se@siDCBLD2. **p < 0.01 versus control. b The protein level of DCBLD2 in HCT-116 cells treated with RGDfC-Se@siDCBLD2 or RGDfC-Se@siDCBLD2. The untreated HCT-116 cells were set as a control group. c In vitro cytotoxicity of RGDfC-Se@siDCBLD2 and RGDfC-Se@siNC at various siRNA concentrations on HCT-116 cells after 48 h incubation. d Cell viability of NCM460 cells after treatment with RGDfC-Se@siDCBLD2 for 48 h at various siDCBLD2 concentrations
