Hypoxia malady

Novus Biologicals:⁴⁵ Hypoxia is a pathological condition in which the body as a whole (generalized hypoxia) or region of the body (tissue hypoxia) is deprived of adequate oxygen supply. Hypoxia contributes significantly to the pathophysiology of major categories of human disease, including myocardial and cerebral ischemia, cancer, pulmonary hypertension, congenital heart disease and chronic obstructive pulmonary disease. Hypoxia inducible factor-1 (HIF-1) is a transcription factor that regulates adaptive responses to a lack of oxygen in mammalian cells. HIF-1 consists of two proteins, HIF-1 alpha and HIF-1 beta. HIF-1 alpha accumulates under hypoxic conditions whereas HIF-1 beta is constitutively expressed. HIF-1 alpha is an important mediator of the hypoxic response of tumor cells and controls the up-regulation of a number of factors important for solid tumor expansion including the angiogenic factor VEGF.

MalaCards: Hypoxia is related to breast cancer and pancreatitis. An important gene associated with Hypoxia is EGLN2 (egl-9 family hypoxia-inducible factor 2), and among its related pathways are Cellular response to hypoxia and Pathways in cancer. The compounds oxygen and proline have been mentioned in the context of this disorder. Affiliated tissues include brain and heart, and related mouse phenotypes are homeostasis/metabolism and mortality/aging.

NINDS:⁴³ Cerebral hypoxia refers to a condition in which there is a decrease of oxygen supply to the brain even though there is adequate blood flow. Drowning, strangling, choking, suffocation, cardiac arrest, head trauma, carbon monoxide poisoning, and complications of general anesthesia can create conditions that can lead to cerebral hypoxia. Symptoms of mild cerebral hypoxia include inattentiveness, poor judgment, memory loss, and a decrease in motor coordination. Brain cells are extremely sensitive to oxygen deprivation and can begin to die within five minutes after oxygen supply has been cut off. When hypoxia lasts for longer periods of time, it can cause coma, seizures, and even brain death.
