WebClinically, hypoxia is associated with metastasis and poor survival in variety of cancer patients. 76–79 Hypoxia selects for cells with low apoptotic potential and increases genomic instability, allowing for rapid mutational adaptations. 80–82 In addition, hypoxia directly increases the expression of genes involved in glycolysis ... WebHypoxia in non-small cell lung cancer (NSCLC) affects cancer progression, metastasis and metabolism. We previously showed that FAM13A was induced by hypoxia in NSCLC but the biological function of this gene has not been fully elucidated. This study aimed to investigate the role of hypoxia-induced FAM13A in NSCLC progression and metastasis.
