WNT5A and neoplasm: Tumors from the mice injected with miR-876-5p-transfected MGC803 cells were smaller than that derived from mimics control-transfected mice; in miR-876-5p and si-WNT5A or si-MITF group, overexpression of WNT5A or MITF mitigated the inhibitory effects of miR-876-5p on tumor size (Figure 6A).
