Inflammatory Hypoxia: Role of Hypoxia-Inducible Factor [PDF]
Cell Cycle, 2004 Sites of inflammation are characterized by significant changes in metabolic activity. Shifts in energy supply and demand can result in diminished delivery and/or availability of oxygen, leading to inflammation-associated tissue hypoxia and metabolic acidosis. These shifts in tissue metabolism, as indicated by previous studies, are frequently associated

Oxydative stress in type 2 diabetic patients: involvement of HIF-1 alpha AND mTOR genes expression [PDF]
The Ukrainian Biochemical Journal, 2023 Biochemical and genetic mechanisms of oxidative stress (OS) developing in the blood of patients with type 2 Diabetes mellitus (T2DM) were studied. Twenty patients with T2DM and 10 healthy persons participated in this study.

Hypoxia and Hypoxia-Inducible Factors in Lymphedema
Frontiers in Pharmacology, 2022 Lymphedema is a chronic inflammatory disorder characterized by edema, fat deposition, and fibrotic tissue remodeling. Despite significant advances in lymphatic biology research, our knowledge of lymphedema pathology is incomplete. Currently, there is no approved pharmacological therapy for this debilitating disease.

Pulmonary Circulation, 2020 In some subjects, high-altitude hypobaric hypoxia leads to high-altitude pulmonary hypertension. The threshold for the diagnosis of high-altitude pulmonary hypertension is a mean pulmonary artery pressure of 30 mmHg, even though for general pulmonary ...

Hypoxia and hypoxia-inducible factors in neuroblastoma [PDF]
Cell and Tissue Research, 2017 Hypoxia (i.e., low oxygen levels) is a known feature of aggressive tumors. Cells, including tumor cells, respond to conditions of insufficient oxygen by activating a transcriptional program mainly driven by hypoxia-inducible factors (HIF)-1 and HIF-2.

Research progress of orexin on the regulation of cardiovascular activities [PDF]
Jichu yixue yu linchuang, 2023 Orexin(OX) is a neuropeptide mainly released by the hypothalamus. In the central nervous system, orexin neurons form extensive connections with other neuronal nuclei and participate in energy metabolism, sleep cycle and cardiovascular activity regulation.

Pulmonary Circulation, 2020 In healthy vascular endothelium, nitric oxide acts as a vasodilator paracrine mediator on adjacent smooth muscle cells. By activating soluble guanylyl cyclase, nitric oxide stimulates cyclic guanosine monophosphate (cGMP) which causes relaxation of ...

Hypoxia. 2. Hypoxia regulates cellular metabolism
American Journal of Physiology-Cell Physiology, 2011 Adaptation to lowering oxygen levels (hypoxia) requires coordinated downregulation of metabolic demand and supply to prevent a mismatch in ATP utilization and production that might culminate in a bioenergetic collapse. Hypoxia diminishes ATP utilization by downregulating protein translation and the activity of the Na-K-ATPase.
