Fig 5. c-Myc is required for EMT and chemotherapy resistance by SALL4-induced.

Fig 5

(A) The expression of c-Myc was positively associated with that of SALL4 in Ishikawa and AN3CA cells by western blotting analysis. (B) c-Myc was a direct target of SALL4 through ChIP assay. (C) Downregulation of c-Myc by specific siRNA reduced SALL4-induced invasion in Ishikawa cells overexpressing SALL4 by transwell assay. (D)(E) Downregulation of c-Myc reduced SALL4-induced drug resistance in Ishikawa cells overexpressing SALL4 through viability assay and clone formation assay. (F) The expression of EMT-related markers and ABCB1 was assessed by western blotting in Ishikawa cells. (G)(H) The mRNA levels of c-Myc, E-cadherin and N-cadherin were detected through qRT-PCR in Ishikawa cells. **P<0.01.
