In addition, the viability of SiHa-Slug and C33A-Slug cells was also much lower than that of their respective control cells (SiHa-GFP and C33A-GFP) (Figure 2E and 2H; p < 0.01), suggesting that the Slug protein may suppress the proliferation of cervical cancer cells. The gene discussed is SNAI2; the disease is cervical cancer.
