Knockdown of LOXL2 downregulates BIRC3 and MDM2 in LCSCs. Western blotting and PCR of CD133+ (A,B) HepG2 and (C,D) Hep3B cells were performed upon LOXL2 knockdown to determine the expression of BIRC3 and MDM2 by transfected with shRNA lentiviral vector (LOXL2-LV/NC-LV) or siRNAs (LOXL2-siRNA/NC-siRNA) respectively. Relative intensity values for the proteins were obtained using Image J software. (E,F) Immunofluorescence staining was performed for BIRC3 and MDM2 in CD133+HepG2 cells upon LOXL2 knockdown. Scale bar: 200 µM. Mean fluorescence intensity values were obtained using Image J software. The data were analyzed upon three independent experiments. *, P<0.05; **, P<0.01; ***, P<0.001. BIRC3, baculoviral inhibitor of apoptosis protein repeat-containing 3; MDM2, murine double minute 2; NC-LV, lentiviral vector against negative control; LOXL2-LV, lentiviral vector against LOXL2; LOXL2, lysyl oxidase-like 2; LOXL2-siRNA, siRNAs against LOXL2; NC-siRNA, siRNAs against negative control; LCSCs, liver cancer stem cells.
