The hypoxia–reoxygenation stress in plants [PDF]

Journal of Experimental Botany, 2020
Plants are very plastic in adapting growth and development to changing adverse environmental conditions. This feature will be essential for plants to survive climate changes characterized by extreme temperatures and rainfall.

Oxidative stress and apoptosis after acute respiratory hypoxia and reoxygenation in rat brain

Redox Biology, 2017
Acute hypoxia increases the formation of reactive oxygen species (ROS) in the brain. However, the effect of reoxygenation, unavoidable to achieve full recovery of the hypoxic organ, has not been clearly established.

Comparative Transcriptome Analysis of Waterlogging-Sensitive and Waterlogging-Tolerant Chrysanthemum morifolium Cultivars under Waterlogging Stress and Reoxygenation Conditions

International Journal of Molecular Sciences, 2018
Waterlogging stress is among the most severe abiotic stressors in the breeding and the production of Chrysanthemum morifolium. However, the mechanism underlying the response to waterlogging and post-waterlogging reoxygenation in C.

Kaempferol Ameliorates Oxygen-Glucose Deprivation/Reoxygenation-Induced Neuronal Ferroptosis by Activating Nrf2/SLC7A11/GPX4 Axis

Biomolecules, 2021
Kaempferol has been shown to protect cells against cerebral ischemia/reperfusion injury through inhibition of apoptosis. In the present study, we sought to investigate whether ferroptosis is involved in the oxygen-glucose deprivation/reperfusion (OGD/R ...

The Role of the Pyruvate Dehydrogenase Complex in the Development of Ischemic-Reperfusion Syndrome

Кубанский научный медицинский вестник, 2022
Background. One of the key components of energy metabolism is the pyruvate dehydrogenase complex (PDC), the activity of which can be targeted by some cytoprotectors. However, their role remains unclear. It is known that the activation of the PDC in tumor

Long-term hypoxia and reoxygenation induced oxidative stress lead to immunosuppression and apoptosis in golden pompano (Trachinotus blochii)

Frontiers in Marine Science, 2023
The fluctuations of dissolved oxygen (DO) often lead to hypoxia in aquaculture, which has a huge adverse impact on fish. This study mainly investigated the effects of long-term hypoxia on oxidative stress, immune response, and cell apoptosis in the liver

Overcoming Hypoxia-Induced Drug Resistance via Promotion of Drug Uptake and Reoxygenation by Acousto–Mechanical Oxygen Delivery

Pharmaceutics, 2022
Hypoxia-induced drug resistance (HDR) is a critical issue in cancer therapy. The presence of hypoxic tumor cells impedes drug uptake and reduces the cytotoxicity of chemotherapeutic drugs, leading to HDR and increasing the probability of tumor recurrence

Effects of hypoxia and reoxygenation on mitochondrial functions and transcriptional profiles of isolated brain and muscle porcine cells

Scientific Reports, 2022
Oxygen fluctuations might occur in mammalian tissues under physiological (e.g. at high altitudes) or pathological (e.g. ischemia–reperfusion) conditions.

Mitochondrial alternative NADH dehydrogenases NDA1 and NDA2 promote survival of reoxygenation stress in Arabidopsis by safeguarding photosynthesis and limiting ROS generation.

New Phytologist, 2022
Plant submergence stress is a growing problem for global agriculture. During desubmergence, rising O2 concentrations meet a highly reduced mitochondrial electron transport chain (mETC) in the cells.

Checking in on Hypoxia/Reoxygenation [PDF]

Cell Cycle, 2006
Hypoxia/reoxygenation is a physiological stress that activates the DNA damage pathway. Significantly, this pathway is initiated during hypoxia, in the absence of detectable DNA damage. Our most recent study determined that during hypoxia, Chk 2 is phosphorylated in an ATM-dependent manner.
