The epigenetic landscape of skeletal muscle in response to exercise and aging

open access: yesThe FEBS Journal, EarlyView.
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.

Chromatin: Pushing nucleosomes around

open access: yes, 1996
Nucleosomes assembled on regulatory DNA sites in chromatin repress gene expression; protein factors have now been identified that can help overcome such repression by excluding or remodelling nucleosomes so regulatory sites are accessible to ...

Understanding and addressing resistance to IMiDs immunomodulatory compounds in multiple myeloma

open access: yesThe FEBS Journal, EarlyView.
IMiDs are pivotal in the treatment of multiple myeloma. Mechanisms of resistance comprise cell intrinsic and extrinsic pathways, involving tumour microenvironment, immune cell dysfunction, CRBN‐dependent and independent genetic drivers and epigenetic changes.

Tissue Resident Memory Cells: Friend or Foe?

open access: yesImmunology, EarlyView.
Tissue‐resident memory T cells (TRM cells) are specialised immune cells in barrier tissues like the lungs, skin and gut, providing rapid host defence and tumour surveillance. Their retention and differentiation are regulated by molecules such as CD69, CD103 and TGF‐β. Dysregulation of TRM cells can lead to chronic activation, driving conditions such as

H2A.Z-Containing Nucleosomes Mediate the Thermosensory Response in Arabidopsis

open access: yes, 2010
SummaryPlants are highly sensitive to temperature and can perceive a difference of as little as 1°C. How temperature is sensed and integrated in development is unknown. In a forward genetic screen in Arabidopsis, we have found that nucleosomes containing

Genetic Parameters and Genome‐Wide Association Studies for Fertility and Reproduction Traits in U.S. Katahdin Sheep Based on the Single‐Step GBLUP Methodology

open access: yesJournal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Sheep production contributes to a secure and diverse food and fibre supply in the United States, with growing ethnic diversity strengthening demand. Katahdin is a composite hair‐type sheep breed developed in the United States that has become the most popular breed in many regions of the country and the first one to have genomic selection ...

Transcription of nucleosomes from human chromatin

open access: yes, 1978
Nucleosomes (chromatin subunits) prepared by micrococcal nuclease diges-tion of human nuclei are similar in histone content but substantially reduced in non-histone proteins as compared to undigested chromatin.

Arginine mutation alters binding of a human monoclonal antibody to antigens linked to systemic lupus erythematosus and the antiphospholipid syndrome

open access: yes, 2007
Objective: Previous studies have shown the importance of somatic mutations and arginine residues in the complementarity-determining regions (CDRs) of pathogenic anti-double-stranded DNA (anti-dsDNA) antibodies in human and murine lupus, and in studies of

Transcriptional adapter ADA2 regulates yield and end‐use quality through liquid–liquid phase separation in wheat

open access: yesJournal of Integrative Plant Biology, EarlyView.
The transcriptional adapter ADA2 interacts with the histone acetyltransferase GCN5 to regulate starch and storage protein content in wheat grains through histone acetylation. ADA2 undergoes phase separation and is modulated by GCN5, affecting histone acetyltransferase activity and gene transcription.

Optimized Cas‐SF01 gene‐editing toolbox shortens flowering timing in commercial maize inbred JING724

open access: yesJournal of Integrative Plant Biology, EarlyView.
The gene‐editing tool Cas‐SF01 was optimized to maximize its efficiency in maize. The Cas‐SF01‐TREX2 configuration was superior in enabling high‐purity gene mutations. This toolkit enabled commercial maize to flower seven days earlier without yield loss, thereby securing harvests and accelerating crop breeding.
