Expression analysis of Dusp6, E-cadherin and N-cadherin in EAC tissues and the adjacent non-tumor tissues. (A) The protein expression level of DUSP6 was analysed by western-blot and immunohistochemistry analysis in EAC tumor and adjacent non-tumor tissues. (B) The protein expression level of E-cadherin was analysed by western-blot and immunohistochemistry analysis in EAC tumor and adjacent non-tumor tissues. (C) The protein expression level of N-cadherin was analysed by western-blot and immunohistochemistry analysis in EAC tumor and adjacent non-tumor tissues.Data were presented as Mean ±SD. P < 0.05 was considered as significant.* P < 0.05. Each experiment was performed in triplicate.

Assessment of effects of overexpressing DUSP6 on ERK signalling pathway. The protein level of phosphorylated ERK and ERK were measured using western blot analysis in Ishikawa 3H12 cell lines when DUSP6 was overexpressed. Β-actin served as an internal control. Groups: Negative control, pcD-NA3.1 Vector-alone clones, pcDNA3.1-Dusp6 clones. Data were presented as Mean ±SD. Each experiment was performed in triplicate.
