B3GALNT2 and neoplasm: Despite the positive correlation between B3GALNT2 and tumor size in clinical pathological analysis (Fig. 1f), no significant effect of B3GALNT2 on cell viability test was observed in CCK8 (Fig. 2e) and neither cell cycle nor apoptosis was influenced by B3GALNT2 knockdown in vitro (Additional file 4: Figure S2a–b).
