B4GALT1 regulates LUAD cell proliferation in vitro and in vivo. A MTT assays were used to determine the viability of A549 and PC9 cells transfected with si-B4GALT1 or pcDNA-B4GALT1. B EdU assays were used to analyse the proliferation of A549 and PC9 cells after transfection. C Colony formation assays were performed to detect the clonogenicity of A549 and PC9 cells. D The apoptotic rates of transfected A549 and PC9 cells were analysed using flow cytometry. LR represents early apoptotic cells. UR represents terminal apoptotic cells. E The cell cycles of A549 and PC9 cells were determined by flow cytometry. *P < 0.05, **P < 0.01
