African trypanosomes have a trypanothione-based mitochondrial thiol redox metabolism.

In vitro fertilization-conceived murine embryos show evidence of oxidative and metabolic stress with alteration in lactic acid metabolism.

Nonlinear H₂O₂ scavenging by peroxiredoxins drives acquired stress resistance and replicative lifespan hormesis.

Yeast cells adapt to harmful superoxide generated during mitochondrial oxidative phosphorylation by arresting respiration through mtDNA deletions whose emergence depend on superoxide dismutase 2 and the retrograde pathway.

A time-resolved analysis of protein and RNA concentrations and interactions during proteostasis stress highlights the dominant role of translation regulation and a shift of energy metabolism.

Translation quality control protects the cell from environmental stresses that could potentially lead to the toxic accumulation of non-proteinogenic amino acids in the proteome.

Spermidine-mediated superoxide generation affects iron homeostasis in Escherichia coli.

RecA is inactivated by oxidative stress and repaired by the MsrA/B anti-ROS defense system.

Genetic analysis reveals NADPH oxidase generated reactive oxygen species as signals to re-establish cellular homeostasis during aging via activating a transcriptional response.

Building on previous work (Wang et al., 2014), it is shown that the nucleotide exchange factor of the chaperone BiP (Sil1) unexpectedly facilitates the reduction of oxidized BiP.
