STK11 and non-small cell lung carcinoma: AURK has been involved in phosphorylating liver kinase B1 (LKB1, also known as serine/threonine kinase 11, STK11) resulting in the suppression of the LKB1/adenosine monophosphate-activated protein kinase (AMPK) signaling pathway and the proliferation, invasion, and migration of non-small cell lung cancer (NSCLC) cells (20).
