Mice weight, the size, weight, and volume of tumors were measured, and the pathological changes of the tumor tissue were observed by HE staining, demonstrating that overexpression of miR-MTCO3P38 inhibited tumor growth and development in HCC mice, which was weakened by TMOD1 overexpression (Fig. 4B-F). Here, MTCO3P38 is linked to neoplasm.
