Chromatin folding by the Polycomb group proteins and its elusive role in epigenetic repression

open access: yesThe FEBS Journal, Volume 293, Issue 1, Page 10-25, January 2026.
Genes repressed by the Polycomb system display greater chromatin folding compared to ‘regular’ inactive genes. The associated chromatin compaction, driven by PRC1‐H3K27me3 interactions, is modest and dynamic. This questions traditional models where Polycomb proteins repress transcription by sheltering genes from transcriptional activators.

Structural characterisation of nucleotide sugar short‐chain dehydrogenases/reductases from the thermophilic pseudomurein‐containing methanogen Methanothermobacter thermautotrophicus ΔH

open access: yesThe FEBS Journal, Volume 293, Issue 2, Page 492-513, January 2026.
Nucleotide sugar short‐chain dehydrogenases/reductases (NS‐SDRs) are involved in pseudomurein and capsular polysaccharide formation in methanogenic Archaea. Methanothermobacter thermautotrophicus possesses several NS‐SDRs labelled Mth375, Mth380, Mth373, Mth631 and Mth1789.

Essential Roles of Heparan Sulfate Endosulfatase Sulf1 in Reward and Aversion Learning Through Distinct Dopamine D1 and D2 Receptor Pathways in Male Mice

open access: yesJournal of Neurochemistry, Volume 170, Issue 1, January 2026.
In the nucleus accumbens (NAc), a heparan sulfate endosulfatase Sulf1 is expressed in both dopamine D1 receptor (Drd1) expressing and Drd2‐expressing medium spiny neurons (D1‐MSNs and D2‐MSNs, respectively). Sulf1 knockout (KO) mice showed impairment in both the cocaine‐induced conditioned place preference (CPP) test and inhibitory avoidance (IA) test.

Stress Nutrition in Aquatic Animals: From Definition to Practice

open access: yesReviews in Aquaculture, Volume 18, Issue 1, January 2026.
ABSTRACT Aquaculture faces numerous challenges, with stress being one of the major issues that lead to growth loss, metabolic disorders, weakened immunity, redox imbalance, and organ damage in aquatic animals. Nutritional intervention is one of the effective strategies to address these problems. Traditional research has primarily focused on the impacts

Vitamin C Alleviates Oxidative Stress in Silver Carp (Hypophthalmichthys molitrix) Fingerlings Exposed to Toxicity Induced by Temephos and Buprofezin

open access: yesAquaculture Research, Volume 2026, Issue 1, 2026.
Context Organophosphates and chitin synthesis inhibitor pesticides pose a significant indirect threat to fish populations, necessitating effective remedial measures. Objective Supplementation with vitamin C (Vit C) in fish feed as a counteracting strategy to mitigate pesticides effect was explored in silver carp (Hypophthalmichthys molitrix ...

Risks for human health related to the presence of plant lectins in food

open access: yesEFSA Journal, Volume 24, Issue 1, January 2026.
Abstract The European Commission asked the European Food Safety Authority (EFSA) to assess the risk related to the presence of plant lectins in food. Based on the available evidence, the CONTAM Panel considered only phytohaemagglutinin (PHA), a legume lectin from beans (Phaseolus sp.), for the risk characterisation.
