Although we have provided solid evidence that CaMK2A regulates GSTP1 through NRF2, correlation analysis of the expression level of pCaMK2A/nuclear NRF2 and GSTP1 did not show NRF2 was correlated with either GSTP1 or pCaMK2A in both clinical lung cancer or lung cancer cell lines. This evidence concerns the gene GSTP1 and lung cancer.
