Description
Non-small cell lung cancer (NSCLC) is the leading cause of cancer deaths worldwide. The oxygen-sensitive Hypoxia Inducible Factor (HIF) transcriptional regulators HIF-1 and HIF-2 are overexpressed in many human NSCLCs, and constitutive HIF-2 activity can promote murine lung tumor progression, suggesting that HIF proteins may be effective NSCLC therapeutic targets. To investigate the consequences of inhibiting HIF activity in lung cancers, we deleted Hif-1 or Hif-2 in an established KrasG12D-driven murine NSCLC model. Deletion of Hif-1 had no obvious effect on tumor growth, whereas Hif-2 deletion resulted in an unexpected increase in tumor burden that correlated with reduced expression of the candidate tumor suppressor gene Scgb3a1 (HIN-1).
