Abstract

Alterations in mitochondrial metabolism influence cell differentiation and growth. This process is regulated by the activity of 2-oxoglutarate (2OG)-dependent dioxygenases (2OGDDs) - a diverse superfamily of oxygen-consuming enzymes - through modulation of the epigenetic landscape and transcriptional responses. Recent reports have described the role of mitochondrial metabolites in directing 2OGDD-driven cell-fate switches in stem cells (SCs), immune cells, and cancer cells. An understanding of the metabolic mechanisms underlying 2OGDD autoregulation is required for therapeutic targeting of this system. We propose a model dependent on oxygen and metabolite availability and discuss how this integrates 2OGDD metabolic signalling, the hypoxic transcriptional response, and fate-determining epigenetic changes.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
