PRMT1‐Mediated LDHA Methylation Drives STAT3 Lactylation to Orchestrate Intestinal Inflammation and Tumorigenesis

Advanced Science, Volume 13, Issue 48, 28 August 2026.
This study identifies an immunometabolic axis wherein SAM‐driven PRMT1 methylates LDHA, enhancing its activity. The resultant lactate induces STAT3 K709 lactylation, which stabilizes an active conformation to promote STAT3 phosphorylation and IL‐10 expression.

S-adenosylmethionine deficit disrupts very low-density lipoprotein metabolism promoting liver lipid accumulation in mice

Journal of Lipid Research
Hepatic deletion of methionine adenosyltransferase-1a (Mat1a) in mice reduces S-adenosylmethionine (SAMe), a key methyl donor essential for many biological processes, which promotes the development and progression of metabolic dysfunction-associated ...

Oncometabolites in Cancer Metabolism: Mechanistic Insights and Biomarker Potential‐ A Narrative Review

Health Science Reports, Volume 9, Issue 8, August 2026.
ABSTRACT Background and Aims Cancer cells undergo adaptation in hostile tumor microenvironments and go through extensive metabolic reprogramming for flourishing. Oncogenic transformation caused by mutations in some metabolic enzymes results in the generation of some metabolic intermediates called onco‐metabolites.

Hypermethioninemia in Campania: Results from 10 years of newborn screening

Molecular Genetics and Metabolism Reports, 2019
In the last years tandem mass spectrometry (MS/MS) has become a leading technology used for neonatal screening purposes. Newborn screening by MS/MS on dried blood spot samples (DBS) has one of its items in methionine levels: the knowledge of this ...

A dodecylamine derivative of cyanocobalamin potently inhibits the activities of cobalamin-dependent methylmalonyl-CoA mutase and methionine synthase of Caenorhabditis elegans

FEBS Open Bio, 2014
In this study, we showed that cyanocobalamin dodecylamine, a ribose 5′-carbamate derivative of cyanocobalamin, was absorbed and accumulated to significant levels by Caenorhabditis elegans and was not further metabolized.

Sex-specific dysregulation of cysteine oxidation and the methionine and folate cycles in female cystathionine gamma-lyase null mice: a serendipitous model of the methylfolate trap

Biology Open, 2015
In addition to its role in the endogenous synthesis of cysteine, cystathionine gamma-lyase (CGL) is a major physiological source of the vasorelaxant hydrogen sulfide.

Raptor and Drp1 Function Synthetically to Control Hypoxic Death and the Mitochondrial Network in Caenorhabditis elegans

The FASEB Journal, Volume 40, Issue 13, 15 July 2026.
Hypoxia results in fragmented mitochondria. Whether this fragmentation promotes or prevents cell death is unresolved. Caenorhabditis elegans mutants defective in mitochondrial fission and fusion coupled with a hypoxia resistant Raptor mutant demonstrated that hypoxia‐induced mitochondrial fragmentation occurs without an intact fission machinery and ...

Strain‐Specific Biotransformation of Grape Marc by Lactic Acid Bacteria: Genomic Validation and Gut Microbiota Modulation

Food Frontiers, Volume 7, Issue 4, July 2026.
ABSTRACT Grape marc (GM) is a polyphenol‐rich winery byproduct that remains underutilized due to its complex fiber matrix, which limits the bioaccessibility of bound phenolics. While lactic acid fermentation (LAF) can enhance the release of these compounds, the strain‐specific metabolic fate of GM phenolics during digestion and colonic fermentation ...

Pancreatic Hormones and Hepatic Methionine Adenosyltransferase in the Rat

Experimental Biology and Medicine, 1969
SummaryOur previous finding that hepatic methionine adenosyltransferase varies directly with the level of glucocorticoids prompted the investigation of this enzyme in the catabolic conditions associated with insulin deficiency and during the administration of excess glucagon.
