MAP3K9 and non-small cell lung carcinoma: Performing a Spearman correlation analysis within the NSCLC cells datasets GSE38310, GSE38404 and GSE3125, we found that the expression of CASP3 (caspase 3) and MAP3K9 (mitogen-activated protein kinase 9) inversely correlated with that of KCNN4. MAP3K9 is recognized as part of the JNK pathway and its function is mainly related to apoptosis by inducing the caspase cascade [19].
