Galectin-4 promoted HCC tumor growth in vivo. A. Macroscopic appearance of representative tumor specimens from HCC xenograft model that was injected with LV-control, LV-Gal4, LV-shNon and LV-Gal4 cells, respectively. B. Tumor growth curves for the xenograft model that was injected with LV-control, LV-Gal4, LV-shNon and LV-Gal4 cells. Data were mean ± SEM of 5 animals per group. C. Representative Ki67 stained tumor sections from xenograft model that was injected with LV-control, LV-Gal4, LV-shNon and LV-Gal4 cells, respectively. *P<0.05.
