However, when we inoculated Atad3a-knockdown 4T1 cells into immune-competent BALB/c mice, the growth rate of tumors was reduced in comparison with control cells (Fig. 5a, b; Supplementary information, Fig. S7e, f), suggesting that Atad3a deletion might evoke favorable immune responses to suppress tumor growth. The gene discussed is ATAD3A; the disease is neoplasm.
