Chromatin Modifications Orchestrate DNA Repair Pathway Choice: Epigenetics Strategies for Enhancing CRISPR–Cas9‐Mediated Knock‐In Efficiency

open access: yesCell Proliferation, EarlyView.
Histone modifications at CRISPR–Cas9‐induced DNA double‐strand breaks shape chromatin states and regulate DNA repair pathway choice. Transient epigenetic modulation may provide a promising strategy to enhance CRISPR–Cas9‐mediated gene knock‐in.

Compromised DNA replication in gut cells underlies sensitivity to genotoxic stress in the tardigrade Hypsibius exemplaris

open access: yesThe FEBS Journal, EarlyView.
DNA damage in the tardigrade Hypsibius exemplaris elicits distinct cellular outcomes depending on replication status. While non‐replicating cells tolerate genotoxic stress, constitutively replicating cells undergo irreversible replication failure upon DNA damage, leading to loss of tissue homeostasis, fat depletion, sterility, and organismal death ...

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.

Phosphorylation of BigH1 regulates its expression pattern and promotes embryonic development

open access: yesThe FEBS Journal, EarlyView.
Phosphorylation is a key regulator of the linker histone variant BigH1 during Drosophila embryogenesis. We reveal that N‐terminal phosphorylation promotes the timely removal of BigH1 from chromatin. In contrast, C‐terminal phosphorylation supports early nuclear divisions and embryonic viability.

A comparative analysis of cell death signalling in RNA and DNA virus infections and potential inhibitory strategies

open access: yesThe FEBS Journal, EarlyView.
RNA and DNA viruses can manipulate host cell death through various mechanisms. RNA viruses (H1N1, SARS‐CoV‐2) induce acute apoptosis, necroptosis, and pyroptosis to promote rapid viral transmission and epithelial barrier damage. In contrast, DNA viruses (HSV‐1, EBV) regulate these mechanisms to sustain a lytic‐latency cycle, evade immune response and ...

RNA activation in insects: From emerging evidence to molecular applications

open access: yesInsect Molecular Biology, EarlyView.
Canonical RNA activation involves small RNAs interacting with promoter sequences, but there is also evidence of non‐canonical RNAa in eukaryotes. Emerging evidence suggests the presence of RNAa in insects. RNAa can be utilised as a tool for functional genomic studies in insects.

Genome‐scale evidence for host‐associated lineage divergence in the parasitoid, Microctonus aethiopoides

open access: yesInsect Molecular Biology, EarlyView.
Host associations are primary drivers of genomic divergence, with clear phylogenetic separation observed between strains associated with Hypera and Sitona weevil hosts. Genomic diversity aligns with reproductive modes: sexually reproducing ancestral lineages maintain high heterozygosity, while derived asexual strains exhibit reduced heterozygosity and ...

Molecular Dynamics Simulations of Nucleosomes Containing Histone Variant H2A.J

open access: yes
Histone proteins form the building blocks of chromatin—nucleosomes. Incorporation of alternative histone variants instead of the major (canonical) histones into nucleosomes is a key mechanism enabling epigenetic regulation of genome functioning. In

Interleukin‐12: Central Roles in Immune Regulation and Disease Therapy

open access: yesImmunology &Cell Biology, EarlyView.
IL‐12 levels are tightly regulated to balance effective protective immunity against infections and cancer with the risk of excessive inflammation and autoimmune disease. Both insufficient and excessive IL‐12 activity can therefore be detrimental, highlighting the importance of precisely controlling its production and signaling. ABSTRACT Interleukin‐12 (
