HIF-1stimulates tumor growth
  • High levels of tumor HIF-1a cause aggressive tumor growth and resistance to therapy


  • High levels of tumor HIF-1a are associated with decreased patient survival


  • Experimental studies show that inhibiting HIF-1a with knockout, antisense, shRNA or drugs inhibits tumor growth


  • HIF-1a is a cancer drug target for attacking a vulnerability (Achilles heel) of tumor growth
