Lake thermal structure drives interannual variability in summer anoxia dynamics in a eutrophic lake over 37 years [PDF]

open access: yesHydrology and Earth System Sciences, 2021
The concentration of oxygen is fundamental to lake water quality and ecosystem functioning through its control over habitat availability for organisms, redox reactions, and recycling of organic material.

Small Non-coding RNA Expression and Vertebrate Anoxia Tolerance

open access: yesFrontiers in Genetics, 2018
Background: Extreme anoxia tolerance requires a metabolic depression whose modulation could involve small non-coding RNAs (small ncRNAs), which are specific, rapid, and reversible regulators of gene expression.

Characterization of sub-nuclear changes in Caenorhabditis elegans embryos exposed to brief, intermediate and long-term anoxia to analyze anoxia-induced cell cycle arrest

open access: yesBMC Cell Biology, 2005
Background The soil nematode C. elegans survives oxygen-deprived conditions (anoxia;

Meiofauna winners and losers of coastal hypoxia: case study harpacticoid copepods [PDF]

open access: yesBiogeosciences, 2014
The impact of anoxia on meiobenthic copepod species was assessed by means of a field experiment. Four plexiglass chambers were deployed in situ in 24 m depth to simulate an anoxic event of 9 days, 1 month, 2 months and 10 months.

Role of PON in anoxia-reoxygenation injury: a Drosophila melanogaster transgenic model. [PDF]

open access: yesPLoS ONE, 2014
Paraoxonase 1 (PON1) is a protein found associated with high density lipoprotein (HDL), thought to prevent oxidative modification of low-density lipoprotein (LDL). This enzyme has been implicated in lowering the risk of cardiovascular disease.

Glutathione Depletion Disrupts Redox Homeostasis in an Anoxia-Tolerant Invertebrate

open access: yesAntioxidants, 2023
The upregulation of endogenous antioxidants is a widespread phenomenon in animals that tolerate hypoxia/anoxia for extended periods. The identity of the mobilized antioxidant is often context-dependent and differs among species, tissues, and stresses ...

Newborn hypoxia/anoxia inhibits cardiomyocyte proliferation and decreases cardiomyocyte endowment in the developing heart: role of endothelin-1. [PDF]

open access: yesPLoS ONE, 2015
In the developing heart, cardiomyocytes undergo terminal differentiation during a critical window around birth. Hypoxia is a major stress to preterm infants, yet its effect on the development and maturation of the heart remains unknown.

Diverse Response Pattern to Anoxia in Three Freshwater Turtle Species

open access: yesBiology, 2022
With increasing water eutrophication and global warming, anoxia and hypoxia are becoming more and more common in water environments. Most vertebrates have a limited tolerance to anoxia of only a few minutes, but some species, such as turtles, can survive

MitosRNAs and extreme anoxia tolerance in embryos of the annual killifish Austrofundulus limnaeus

open access: yesScientific Reports, 2019
Embryos of the annual killifish Austrofundulus limnaeus are the most anoxia-tolerant vertebrate. Annual killifish inhabit ephemeral ponds, producing drought and anoxia-tolerant embryos, which allows the species to persist generation after generation ...

Mitochondrial DNA sequence and lack of response to anoxia in the annual killifish Austrofundulus limnaeus

open access: yesFrontiers in Physiology, 2016
The annual killifish Austrofundulus limnaeus inhabits ephemeral ponds in regions of Venezuela, South America. Permanent populations of A. limnaeus are maintained by production of stress-tolerant embryos that are able to persist in the desiccated ...
