EGFR and non-small cell lung carcinoma: To explore the molecular mechanism by which miR-34a contributes to the apoptosis and cell-cycle progression of NSCLC cells, we used miRWalk 2.0 (http://zmf.umm.uni-heidelberg.de/apps/zmf/mirwalk2/) and miRMap (http://mirmap.ezlab.org/) to predict potential targets, and identified EGFR as a potential target for miR-34a.
