“…Recently, a number of studies have suggested that mitochondrial ROS are involved in the stabilization and activation of HIF under hypoxic conditions [21]. It is known that HIF-1α, which is induced by hypoxia, growth factors, and oncogenes, plays a pivotal role in tumor growth and angiogenesis [13]. ROS affect HIF-1α expression under gastric ischemic conditions, suggesting that ROS can regulate HIF-1α expression in gastric ischemia [33].…”

“…This hypoxic region is involved in tumor malignancy and proliferation, resulting in the development of resistance to radiotherapy [12]. Hypoxia-inducible factor-1 (HIF-1), a transcription factor that regulates the cellular response to hypoxia, induces several genes that mediate tumorigenesis [13], [14]. It is known that HIF-1 is a heterodimer that consists of the oxygen-sensitive HIF-1α subunit and the constitutively expressed HIF-1β subunit [15], [16].…”

“…Hypoxia-inducible factor-1 (HIF-1) is a transcriptionally active nuclear protein that is produced by cells under hypoxic conditions and plays a key role in the hypoxic compensatory response of the body (19). HIF-1 is also important in cellular energy production, the metabolism of iron and catecholamines, as well as vasoconstriction, neovascularization and apoptosis in tumor cells under ischemic and hypoxic conditions (20)(21)(22)(23)(24)(25). Previous studies have shown that HIF-1α is a disruptor of the intestinal mucosal barrier during hypoxia, ischemia-reperfusion and inflammation (26,27).…”

“…Більше того, експресія HIF не лише посилюється за умов гіпоксії, а й є також підвищеною в різних злоякісних пухлинах людей і корелює з несприятливим прогно-зом, а пригнічення експресії альфа-субодиниці цього транскрипційного фактора час-то призводить до зниження інтенсивності росту різних злоякісних пухлин [6,[11][12][13][14][15].…”
