Furthermore, both cell growth curves and cell viability assays found that HeLa-shSlug and CasKi-shSlug cells grow much faster than their respective control cells (HeLa-shcontrol and Caski-shcontrol) (Figure 2J, 2M, Figure 2K and 2N; p < 0.01), suggesting that the knockdown of Slug promoted the proliferation of cervical cancer cells. Here, SNAI2 is linked to cervical cancer.
