Atg7 inhibition promotes epithelial-mesenchymal transition through enhanced Warburg effect. Mutational analysis revealed that substitution of Y105 to E105 results in a significant increase glucose consumption(A), lactate production(B) in Atg7 knockdown cells. P values were calculated by One Way ANOVA. *P<0.005, **P<0.001. (C) Western blot analysis of EMT markers in knockdown Atg7 and PKM2. (D) 2DG (inhibitor of glycolysis) administration in Atg7-knockdown cell, Western blot analysis of EMT markers in HCT-116, HeLa and MEF cells. (E) Transwell assay in HCT-116 2DG administration. Original magnification, ×200. Scale bar represents 100 μm. (F) Statistical analysis result of transwell assay in (E). P values were calculated by One Way ANOVA. *P<0.005, **P<0.001.
