The results showed that TUSC8 over-expression reduced the cell invasive capacities in breast cancer cell lines SK-BR-3 and MDA-MB-435 (p < 0.05) (Figure 2E), whereas TUSC8 inhibition enhanced the cell invasive capacities in breast cancer cell lines MCF-7 and HCC1937 (p < 0.05) (Figure 2F). This evidence concerns the gene TUSC8 and breast cancer.
