For example, miR-655 may suppress the proliferation of PCa cells and tumor metastasis by inhibiting TRIM24 (Bai et al., 2021) and miR-30a may inhibit the androgen-independent growth of PCa cells by targeting the expression levels of MYBL2, FOXD1, and SOX4 (Li et al., 2020). This evidence concerns the gene FOXD1 and neoplasm.
