TRIM46 and breast cancer: The cell growth curves and metastasis assay indicated that Trim46-shRNA also inhibited cell proliferation (Figure 3B) and decreased the metastasis nodes in lung tissues (n = 8, p < 0.01, Figure 3C,D), suggesting that Trim46 was the major target of mmu-miR-1894-3p for inhibition of breast cancer cell metastasis.
