Abstract

The folate-driven one-carbon (1C) cycle is a fundamental metabolic hub in cells that enables the synthesis of nucleotides and amino acids and epigenetic modifications. This cycle might also release formaldehyde, a potent protein and DNA crosslinking agent that organisms produce in substantial quantities. Here we show that supplementation with tetrahydrofolate, the essential cofactor of this cycle, and other oxidation-prone folate derivatives kills human, mouse and chicken cells that cannot detoxify formaldehyde or that lack DNA crosslink repair. Notably, formaldehyde is generated from oxidative decomposition of the folate backbone. Furthermore, we find that formaldehyde detoxification in human cells generates formate, and thereby promotes nucleotide synthesis. This supply of 1C units is sufficient to sustain the growth of cells that are unable to use serine, which is the predominant source of 1C units. These findings identify an unexpected source of formaldehyde and, more generally, indicate that the detoxification of this ubiquitous endogenous genotoxin creates a benign 1C unit that can sustain essential metabolism.

  • Two mito-1C metabolism genes, SHMT2 and MTHFD1L, and ESD were identified in the CRISPRko screen.

    “Notably, two mito-1C metabolism genes, SHMT2 and MTHFD1L, and the S-formylglutathione hydrolase gene, ESD, involved in GSH-mediated formaldehyde detoxification (12) were identified in the CRISPRko screen.”

    From Eprenetapopt triggers ferroptosis, inhibits NFS1 cysteine desulfurase, and synergizes with serine and glycine dietary restriction (2022) · cites this paper as [12]

    The section ‘ADH5 fuels the growth of 1C-cycle-deficient cells’ describes S-formylglutathione hydrolase regenerating GSH as part of a formaldehyde-detoxification route. It does not identify that hydrolase as ESD. The citation is attached to the detoxification clause; this source does not report the claimed identification of SHMT2, MTHFD1L and ESD in a CRISPR knockout screen. (LLM, conf=0.83)

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.
