For example, Dong and his colleagues combined their data with TCGA database, showing that NDRG1 regulated EMT‐associated protein expression (Twist1, Snail, VE‐cadherin and vimentin decreased, whereas E‐cadherin increased) in gastric carcinoma, which is negatively correlated with poor prognosis.33 The gene discussed is TWIST1; the disease is gastric carcinoma.
