Autophagy: A cyto-protective mechanism which prevents primary human hepatocyte apoptosis during oxidative stress [PDF]

open access: yes, 2012
The role of autophagy in the response of human hepatocytes to oxidative stress remains unknown. Understanding this process may have important implications for the understanding of basic liver epithelial cell biology and the responses of hepatocytes ...

The biological effect of cobalt chloride mimetic-hypoxia on nucleus pulposus cells and the comparability with physical hypoxia in vitro

open access: yesFrontiers in Bioscience-Landmark, 2021
Objective: Nucleus pulposus cells (NPCs) are cells extracted from the intervertebral disc and are important for research into intervertebral disc degeneration (IVDD). NPCs live in an avascular and relatively hypoxic environment.

SUMOylation of NaV1.2 channels mediates the early response to acute hypoxia in central neurons. [PDF]

open access: yes, 2016
The mechanism for the earliest response of central neurons to hypoxia-an increase in voltage-gated sodium current (INa)-has been unknown. Here, we show that hypoxia activates the Small Ubiquitin-like Modifier (SUMO) pathway in rat cerebellar granule ...

GAS5 silencing attenuates hypoxia‐induced cardiomyocytes injury by targeting miR‐21/PTEN

open access: yesImmunity, Inflammation and Disease, 2023
Introduction Myocardial hypoxia is an important factor causing myocardial infarction (MI). Interestingly, many unknown factors in the molecular mechanism of MI remain unclear.

Hypoxic regulation of ion channel function and expression [PDF]

open access: yes, 2002
Acute hypoxia regulates the activity of specific ion channels in a rapid and reversible manner. Such effects underlie appropriate cellular responses to hypoxia which are designed to initiate cardiorespiratory reflexes and contribute importantly to other ...

Hypoxia in Breast Cancer—Scientific Translation to Therapeutic and Diagnostic Clinical Applications

open access: yesFrontiers in Oncology, 2021
Breast cancer has been the leading cause of female cancer deaths for decades. Intratumoral hypoxia, mainly caused by structural and functional abnormalities in microvasculature, is often associated with a more aggressive phenotype, increased risk of ...

Local lung hypoxia determines epithelial fate decisions during alveolar regeneration. [PDF]

open access: yes, 2017
After influenza infection, lineage-negative epithelial progenitors (LNEPs) exhibit a binary response to reconstitute epithelial barriers: activating a Notch-dependent ΔNp63/cytokeratin 5 (Krt5) remodelling program or differentiating into alveolar type II

Effects of exposure to a DNA damaging agent on the hypoxia inducible factors in organogenesis stage mouse limbs. [PDF]

open access: yesPLoS ONE, 2012
Hypoxia plays a critical role in coordinating cell survival, differentiation and death in normal embryogenesis; during limb pattern formation, hypoxia affects two key processes, chondrogenesis and cell death.

Effect of Mesenchymal Stem Cells Overexpressing BMP-9 Primed with Hypoxia on BMP Targets, Osteoblast Differentiation and Bone Repair

open access: yesBiology, 2023
Bone formation is driven by many signaling molecules including bone morphogenetic protein 9 (BMP-9) and hypoxia-inducible factor 1-alpha (HIF-1α). We demonstrated that cell therapy using mesenchymal stem cells (MSCs) overexpressing BMP-9 (MSCs+BMP-9 ...

Hypoxia, Metabolism and Immune Cell Function [PDF]

open access: yesBiomedicines, 2018
Hypoxia is a hallmark of inflamed, infected or damaged tissue, and the adaptation to inadequate tissue oxygenation is regulated by hypoxia-inducible factors (HIFs). HIFs are key mediators of the cellular response to hypoxia, but they are also associated with pathological stress such as inflammation, bacteriological infection or cancer.
