Cancer cell hypoxia
WebApr 12, 2024 · Hypoxia is associated with numerous tumor hallmarks, such as cell proliferation, angiogenesis, metabolic reprogramming, and radiation resistance, and can also induce EMT and ROS phenotypes in advanced tumor cells, thus promoting cell invasion and metastasis [31,32, 33]. WebIt causes symptoms like confusion, restlessness, difficulty breathing, rapid heart rate, and bluish skin. Many chronic heart and lung conditions can put you at risk for hypoxia. Hypoxia can be life-threatening. If you are experiencing symptoms of hypoxia, call 911 or go to the nearest ER. Appointments 216.444.6503.
