An unbiased genome-wide human forward genetic screen identifies the vacuolar ATPase complex and assembly factors as regulators of HIF stability through their actions on intracellular iron metabolism.

The protein uS12/Rps23 functions extra-ribosomally to control oxygen homeostasis in fission yeast.

Assays using recombinant HIF prolyl hydroxylases did not support hydroxylation of more than 20 reported non-HIF substrates under conditions where robust HIF hydroxylation was observed.

Cells rely on prolyl hydroxylase enzymes to sense low levels of oxygen, but they might act on fewer targets than previously thought.

Parasitic helminths infect over a billion humans and use unusual anaerobic metabolism that needs a rare electron carrier, Rhodoquinone (RQ), whose synthesis requires the kynurenine pathway of tryptophan degradation.

As the first fully genetically encoded method, PARIS allows cell-specific, long-term, repeated measurements of gap junctional coupling with high spatiotemporal resolution, facilitating its study in both health and disease.

The first genomic view of beetle luciferase evolution indicates evolutionary independence of luciferase between fireflies and click-beetles, and provide valuable datasets which will accelerate the discovery of new biotechnological tools.

Sponges and ctenophores lack hypoxia-inducible factors, suggesting that the metazoan last common ancestor could have lived aerobically under severe hypoxia and did not need to regulate its transcription in response to oxygen availability.

A new type of hybrid nonribosomal peptide synthetase (NRPS)-like-pteridine synthase biosynthetic pathway has been illuminated via genome mining.
