For example, Liu et al. suggested that hsa-miR-497-5p inhibited breast cancer cell proliferation, invasion, and survival by targeting SMAD7 (38); Wang et al. showed that hsa-miR-497-5p suppressed tumor growth and angiogenesis through modulating IRS1 in breast cancer (39); Li et al. found that hsa-miR-29c-3p played a suppressive role in breast cancer by inhibiting the TIMP3/STAT1/FOXO1 pathway (40). Here, SMAD7 is linked to neoplasm.
