Images of mice and tumors in the OV-TP53 and OV-TP53+OV-miR-424-5p groups are shown in Fig. 6A. Statistics revealed that the mass and volume of the tumor were lower significantly in the OV-TP53 group compared to the DDP group, and this phenomenon was restored in the OV-TP53+OV-miR-424-5p group (Fig. 6B–C). This evidence concerns the gene TP53 and neoplasm.
