KRAS and lung cancer: To test this, we systematically analyzed the temporal gene expression dynamic patterns during the EMT in NSCLC using data derived from lung cancer cell lines induced to undergo EMT using data collected at multiple time points during the slow transition of cells going from E to M. Previously, we and others have shown that the EMT gene expression patterns are generally conserved between two EMT-induced lung adenocarcinoma KRAS mutant cell lines, H358 and A549 [6, 16, 17].
