Veterinary Medicine and Science, Volume 12, Issue 6, November 2026.Dietary crude protein and methionine interact significantly in Japanese quail. Optimal methionine ranges from 0.50%–0.70% depending on protein level and phase. Best grower performance occurs at 25% CP with 1.30% Met, yielding 161.84 g male weight gain. Females show superior breast yield (30.90%).

Aging Cell, Volume 25, Issue 11, November 2026.Targeted metabolomics of gill and mantle tissues from five marine bivalve species spanning lifespans from approximately 30 to over 500 years revealed longevity‐associated metabolic signatures. Longer‐lived species exhibited reduced free amino acid pools, lactate, pyruvate‐related ratios, fumarate and malate, alongside increased succinate‐to‐fumarate ...

A sterospecific colorimetric assay for (s,s)-Adenosylmethionine quantification based on thiopurine methyltransferase-catalyzed thiol methylation [PDF]
, 2002 S-Adenosyl-L-methionine (AdoMet or SAM) that is biologically synthesized by AdoMet synthetase bears an s-configuration at the sulfur atom. The chiral sulfonium spontaneously racemizes to form a mixture of s-and R-isomers of AdoMet under physiological ...

Aging Cell, Volume 25, Issue 11, November 2026.This review examines how histone modifications integrate aging, metabolic dysfunction and neuroinflammation to shape persistent, cell‐type‐specific chromatin states in Alzheimer's disease. By distinguishing causal regulation from association through perturbation, persistence and reversibility, it highlights metabolic–epigenetic feedback loops and ...

Methionine Regulates Antitumour Function of CD8+ T Cells Through Polyamine Synthesis
Immunology, Volume 179, Issue 3, Page 418-433, November 2026.Methionine restriction in vitro enhances CD8+ T cell effector function by suppressing polyamine synthesis and progressively induces the co‐expression of PD‐1 and TIM‐3. Consistently, sustained dietary methionine restriction diminishes the efficacy of adoptive T cell therapy (ACT) and promotes the expression of terminal exhaustion‐associated markers ...

New Phytologist, Volume 252, Issue 3, Page 1327-1342, November 2026.We extend a widely used C3‐photosynthesis model to account for various photorespiratory bypasses, thereby, providing a useful resource and framework that enforces future novel bypass work and scrutinize if the results go counter to theory. Our model analyses show that of the 17 published bypass pathways, full‐decarboxylating bypasses (that have been ...

The synthesis of the N-methyl analogue of S-adenosylmethionine; N.M.R. observation of diastereomers
, 1983 The N-methyl analogue (1; X = N-Me) of S-adenosylmethionine has been synthesized; the intermediates and the end-product are racemic at the amino acid α-carbon, and show diastereomeric splitting in their 13C n.m.r. spectra.

The FASEB Journal, Volume 40, Issue 20, 31 October 2026.A maternal western diet (WD) and betaine supplementation during suckling influence metabolic programming. A maternal WD induced adverse metabolic effects in offspring, accompanied by altered FGF21‐related gene expression and decreased Akkermansia muciniphila abundance.
