KRAS and lung adenocarcinoma: As the mouse lung adenocarcinoma was induced by the P53 knockout and K‐rasG12D expression, it was expected that some of these identified lncRNAs were associated with the status of p53 and Kras. The mouse lung adenocarcinoma cells (KP cells) were isolated from the cancer tissues, and the deletion of P53 and Kras‐G12D mutation was confirmed in the KP cells.
