The generation of the stable overexpression and knockdown cell lines. (a) The expression of CHI3L1 in the HepG2, HepG2.2.15, Bel7404, MHCC97L and HCCLM3 by Two-step RT-PCR and the grayscale of the strips were showed. (b) Immunofluorescence was showed CHI3L1 overexpression in HepG2 and Bel7404 cells. Cell nucleus was stained with DAPI (blue fluorescence) and CHI3L1 was stained with FITC (green fluorescence). (c) The expression of CHI3L1 in the HepG2 and Bel7404 cells after transfected with three short-hairpin RNAs. All samples were normalized to the housekeeping gene GAPDH. (d) qPCR showing the expression of CHI3L1 in the CHI3L1 overexpression and knockdown cell lines. Scale bar represents 100 μm. Error bars represents SD calculated from three independent experiments. **Represents p < 0.01 by two-tailed t test.
