Oxygen Homeostasis in Health and Disease

Every nucleated cell in the body is capable of sensing a reduction in oxygen concentration and responding by activation of HIF-1.

Albert Einstein College of Medicine – Montefiore Medical Center designates this enduring material activity for a maximum of 1.0 AMA PRA Category 1 Credit(s)™. Physicians should claim only the credit commensurate with the extent of their participation in the activity.

In support of improving patient care, this activity has been planned and implemented by Albert Einstein College of Medicine-Montefiore Medical Center and InterMDnet. Albert Einstein College of Medicine – Montefiore Medical Center is jointly accredited by the Accreditation Council for Continuing Medical Education (ACCME), the Accreditation Council for Pharmacy Education (ACPE), and the American Nurses Credentialing Center (ANCC), to provide continuing education for the healthcare team.

Learning Objectives

Upon completion of this Cyberounds®, you should be able to:

  • Discuss the molecular mechanisms by which changes in cellular PO2 are sensed and transduced to changes in gene expression through the activity of HIF-1

  • Discuss the role of HIF-1 and its downstream gene products in mediating adaptive responses to tissue ischemia and relevant translational research

  • Discuss the role of HIF-1 in the pathogenesis of cancer and relevant translational research.
