Hypoxia Upregulates Estrogen Receptor β in Pulmonary Artery Endothelial Cells in a HIF-1α-Dependent Manner [PDF]

open access: yes, 2018
17β-Estradiol (E2) attenuates hypoxia-induced pulmonary hypertension (HPH) through estrogen receptor (ER)-dependent effects, including inhibition of hypoxia-induced endothelial cell proliferation; however, the mechanisms responsible for this remain ...

Hypoxia, Hypoxia-Inducible Factors and Liver Fibrosis [PDF]

open access: yesCells, 2021
Liver fibrosis is a potentially reversible pathophysiological event, leading to excess deposition of extracellular matrix (ECM) components and taking place as the net result of liver fibrogenesis, a dynamic and highly integrated process occurring during chronic liver injury of any etiology.

Long-term chronic intermittent hypoxia: a particular form of chronic high-altitude pulmonary hypertension

open access: yesPulmonary 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 ...

Oxydative stress in type 2 diabetic patients: involvement of HIF-1 alpha AND mTOR genes expression [PDF]

open access: yesThe 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 activates IKK-NF-κB and the immune response in Drosophila melanogaster [PDF]

open access: yes, 2014
Hypoxia, or low oxygen availability, is an important physiological and pathological stimulus for multicellular organisms. Molecularly, hypoxia activates a transcriptional programme directed at restoration of oxygen homoeostasis and cellular survival.

Hypoxia, Metabolic Reprogramming, and Drug Resistance in Liver Cancer

open access: yesCells, 2021
Hypoxia, low oxygen (O2) level, is a hallmark of solid cancers, especially hepatocellular carcinoma (HCC), one of the most common and fatal cancers worldwide. Hypoxia contributes to drug resistance in cancer through various molecular mechanisms.

The Influence of Body Size and Hemoglobin Multiplicity on Critical Oxygen Threshold in Red Drum (Sciaenops ocellatus) [PDF]

open access: yes, 2016
Hypoxia is common in marine environments and fishes use a suite of cardiorespiratory adjustments to defend aerobic metabolism, including reducing standard metabolic rate (SMR), the minimum metabolic rate needed to sustain life at a specified temperature,

Role of hypoxia in cancer therapy by regulating the tumor microenvironment

open access: yesMolecular Cancer, 2019
Clinical resistance is a complex phenomenon in major human cancers involving multifactorial mechanisms, and hypoxia is one of the key components that affect the cellular expression program and lead to therapy resistance.

Regulation of glycolysis by the hypoxia‐inducible factor (HIF): implications for cellular physiology

open access: yesJournal of Physiology, 2020
Under conditions of hypoxia, most eukaryotic cells can shift their primary metabolic strategy from predominantly mitochondrial respiration towards increased glycolysis to maintain ATP levels.

The Effect of Hypoxia on the Expression of CXC Chemokines and CXC Chemokine Receptors—A Review of Literature

open access: yesInternational Journal of Molecular Sciences, 2021
Hypoxia is an integral component of the tumor microenvironment. Either as chronic or cycling hypoxia, it exerts a similar effect on cancer processes by activating hypoxia-inducible factor-1 (HIF-1) and nuclear factor (NF-κB), with cycling hypoxia showing
