Cytoskeletal Arrest: An Anoxia Tolerance Mechanism

Metabolites, 2021
Polymerization of actin filaments and microtubules constitutes a ubiquitous demand for cellular adenosine-5′-triphosphate (ATP) and guanosine-5′-triphosphate (GTP). In anoxia-tolerant animals, ATP consumption is minimized during overwintering conditions,

Viability assessment and transplantation of fatty liver grafts using end‐ischemic normothermic machine perfusion

Liver Transplantation, EarlyView., 2022
Abstract End‐ischemic viability testing by normothermic machine perfusion (NMP) represents an effective strategy to recover liver grafts having initially been discarded for liver transplantation (LT). However, its results in the setting of significant (≥30%) macrovesicular steatosis (MaS) have not been specifically assessed.

Anoxia-reoxygenation regulates mitochondrial dynamics through the hypoxia response pathway, SKN-1/Nrf, and stomatin-like protein STL-1/SLP-2. [PDF]

PLoS Genetics, 2013
Many aerobic organisms encounter oxygen-deprived environments and thus must have adaptive mechanisms to survive such stress. It is important to understand how mitochondria respond to oxygen deprivation given the critical role they play in using oxygen to

Toarcian oceanic anoxic event: An assessment of global causes using belemnite C isotope records [PDF]

, 2005
Two hypotheses have been proposed to explain simultaneous large negative excursions (up to 7% PeeDee belemnite) in bulk carbonate (delta(13)C(carb)) and organic carbon isotope records (delta(13)C(org)) from black shales marking the Toarcian oceanic ...

Mitochondrial matrix pH acidifies during anoxia and is maintained by the F1Fo‐ATPase in anoxia‐tolerant painted turtle cortical neurons

FEBS Open Bio, 2019
The western painted turtle (Chrysemys picta bellii) can survive extended periods of anoxia via a series of mechanisms that serve to reduce its energetic needs.

Metazoans of redoxcline sediments in Mediterranean deep-sea hypersaline anoxic basins [PDF]

, 2015
Background: The deep-sea hypersaline anoxic basins (DHABs) of the Mediterranean (water depth similar to 3500 m) are some of the most extreme oceanic habitats known.

Nitrate reductase regulation in tomato roots by exogenous nitrate: a possible role in tolerance to long-term root anoxia [PDF]

, 2004
The mechanism of nitrate reductase (NR) regulation under long-term anoxia in roots of whole plants and the putative role of nitrate in anoxia tolerance have been addressed.

The fate of the homoctenids (Tentaculitoidea) during the Frasnian-Famennian mass extinction (Late Devonian) [PDF]

, 2006
The homoctenids (Tentaculitoidea) are small, conical-shelled marine animals which are amongst the most abundant and widespread of all Late Devonian fossils.

Transcriptomic responses of sponge holobionts to in situ, seasonal anoxia and hypoxia

Peer Community Journal
Deoxygenation can be fatal for many marine animals; however, some sponge species are tolerant of hypoxia and anoxia. Indeed, two sponge species, Eurypon sp. 2 and Hymeraphia stellifera, survive seasonal anoxia for months at a time.
