Abstract
Objective. Analysis and synthesis of literature data on morphological and functional properties and the diagnostic value of induced factor hypoxia. Methods. The basis of this study was a review of literature on this topic. Results. An important role in the adaptation of the organism to hypoxia belongs to a specific regulatory protein - hypoxia-induced factor (HIF), the activity of which increases with decreasing oxygen tension in the blood. HIF is a heterodimeric protein, the beta subunit of which is constantly expressed, and the synthesis of the alpha subunit is regulated by oxygen. Conclusion. Acute oxygen deficiency is the basis of a variety of pathological processes in many diseases and environmental factors. The hypoxia-induced factor is responsible for the formation of long-term adaptation to hypoxia, and therefore is a suitable target for pharmacological effects. The search for drugs that act as inducers or inhibitors of its synthesis is an important area in experimental pharmacology, since it allows not only to regulate the processes of adaptation to hypoxia, but more effectively treat cerebrovascular, cardiovascular, oncological and other diseases in whose genesis the leading role plays oxygen deficiency.
