ABSTRACT Organophosphate esters (OPEs) are found ubiquitously in the environment and exposure to these chemicals has induced behavioral, developmental, and morphological impairments in several model organisms. Yet there is still a lack of understanding of how sub‐lethal exposure disrupts organism function at the molecular‐level, especially for Daphnia ...

S‐Adenosylmethionine (SAM) hydrolases counter increased SAM epimerisation in thermophilic archaea
S‐Adenosyl‐l‐methionine (SAM) is a vital enzyme cofactor. Epimerisation at the sulfonium centre of biologically active (SS,SCα)‐SAM is driven by heat, yielding biologically inactive (RS,SCα)‐SAM. Here, two novel archaeal SAM hydrolases from the thermophilic Sulfolobus acidocaldarius and the halophilic Haloferax volcanii are shown to cleave (RS,SCα)‐SAM.

OBJECTIVE: The aim of this study was to evaluate plasma homocysteine (Hcy), malondialdehyde (MDA), glutathione (GSH) levels, glutathione peroxidase (GSH-Px) and glutathione-S-transferase (GST) activities and liver tissue S-adenosylmethionine (SAM) and S ...

The epigenetic landscape of skeletal muscle in response to exercise and aging
Epigenetic mechanisms regulate gene expression in response to exercise and aging, thereby supporting skeletal muscle plasticity. Acute exercise induces chromatin remodeling through histone modifications and DNA methylation, promoting the expression of exercise‐responsive genes.

S-adenosylmethionine in rat liver cirrhosis
An experimental model of cirrhosis in rats, by means carbon tetrachloride (CCl4) and ethanol during two months, was used to assess the effectiveness of S-adenosylmethionine.

CD36‐mediated lipid rewiring in the metabolic adaptation of tumour ecosystems
Nutrient deprivation drives a lipid‐centric shift in tumour metabolic symbiosis and signalling network. CD36 functions as a bidirectional bridge, transferring fatty acids from stromal donors (adipocytes, CAFs) to the ecosystem tumour‐ and microenvironment‐dependently.

Cystathionine‐β‐synthase (CBS) helps remove harmful homocysteine and supports the production of protective sulfur‐containing molecules. Using its natural activator, S‐adenosyl‐l‐methionine, as a template, we designed and tested 15 analogues. Three activated and stabilized the enzyme, including the newly identified S‐2‐amino‐adenosyl‐l‐methionine. These
