This research aims to expose the role of mitochondrial creatine kinase 1 (CKMT1) in non-small cell lung cancer (NSCLC) progression and hypoxia adaptation. The mRNA and protein expression of CKMT1 in NSCLC tissues were detected byusing GEPIA web, immunohistochemistry and qRT-PCR. For hypoxia, cells were exposed to the 1% O atmosphere. The protein levels of HIF-1α and CKMT1 in H1650 and H1299 cells exposed to hypoxia were determined by western blot. The roles of CKMT1 on the proliferation, invasion and hypoxia adaptation of NSCLC cells were measured by CCK8, colony formation and transwell assays. Luciferase activity assay and HIF1 specific inhibitor (LW6) assay indicated the related function of hypoxia and CKMT1. CKMT1 was highly expressed in NSCLC tissues, and the high level of CKMT1 was significantly correlated with the high pathological grade of NSCLC. Knockdown of CKMT1 inhibited the cell proliferation and invasion of H1650 and H1299 cells, which could be rescued by hypoxia. Hypoxia induced the accumulation of HIF-1α and the expression of CKMT1 in H1650 and H1299 cells. Furthermore, HIF-1 as a transcription factor of CKMT1, could up-regulated the expression of CKMT1 under hypoxia. In summary, CKMT1 has the potential as a target for NSCLC hypoxic targeted therapy. In summary, CKMT1 has the potential as a target for NSCLC hypoxic targeted therapy. Directed evolution (DE) is a technique for protein engineering that involves iterative rounds of mutagenesis and screening to search for sequences that optimize a given property, such as binding affinity to a specified target. Unfortunately, the underlying optimization problem is under-determined, and so mutations introduced to improve the specified property may come at the expense of unmeasured, but nevertheless important properties (ex. solubility, thermostability
