Highly invasive human CRC LoVo and HCT116 cells were cultured with PBS (control), 100 μM calycosin, 20 ng/mL TGF-β, or calycosin with TGF-β for 48 h The expression of vimentin, Snail, N-cadherin was promoted by TGF-β (P < 0.05) and suppressed by calycosin (P < 0.05) in HCT116 (Fig. 7a) and LoVo cells (Fig. 7b). The gene discussed is SNAI1; the disease is colorectal carcinoma.
