The results of CCK-8 and colony formation assay suggested that LINC01574 knockdown sharply restrained the proliferation rate and colony formation of BC cells, while overexpression of TTYH3 could partially attenuate the inhibitory function of shLINC01574 on the proliferative and colony formation of BC cells (Figures 7(c) and 7(d)). This evidence concerns the gene TTYH3 and breast cancer.
