Homologous recombination mutants cause differing lethality between h− and h+ Schizosaccharomyces pombe strains due to mat1 heterochromatin

The FEBS Journal, EarlyView.
Homologous recombination (HR) in Schizosaccharomyces pombe is essential when mating‐type switching–induced double‐strand breaks (DSBs) form at the mat1 locus. In h90 and h− strains, efficient mat1 DSB formation renders HR indispensable unless suppressors block these breaks.

RAB4A acts as a negative feedback regulator of extracellular vesicle secretion during TGF‐β signaling

The FEBS Journal, EarlyView.
TGF‐β signaling regulates extracellular vesicle (EV) release in cancer cells by modulating the expression and activity of genes associated with EV biogenesis. The TGF‐β‐induced upregulation of RAB4A expression facilitates fast endosomal recycling, a process that limits the fusion of multivesicular bodies with the plasma membrane and EV secretion. Hence,

Disruption of iron metabolism resulting from Dmt1/Slc11a2 deficiency compromises Notch protein degradation and transcriptional activation

The FEBS Journal, EarlyView.
Divalent metal transporter 1 (Dmt1) maintains iron homeostasis and lysosomal proteostasis required for physiological Notch receptor–ligand signaling. Dmt1 loss lowers iron storage capacity (ferritin), increasing intracellular Fe2+, driving ROS and lipid peroxidation, and leading to lysosomal/mitochondrial dysfunction.

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

The 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.

Role of the UHRF1–KLHL6–CORO2B axis in obesity‐related insulin resistance

Journal of Diabetes Investigation, EarlyView.
In high‐fat diet (HFD)‐induced obese mice with insulin resistance, overexpression of UHRF1 may recruit DNMT1 to promote DNA methylation of KLHL6, leading to its downregulation. Subsequently, suppression of KLHL6 may decrease the ubiquitination of CORO2B, resulting in elevated CORO2B protein levels.

The transcription factors TaABI4 and TaNAC‐A1 fine‐tune TaCYP94‐A1 transcription to modulate seed dormancy in wheat

Journal of Integrative Plant Biology, EarlyView.
A module involving the transcription factors TaABI4 and TaNAC‐A1, and the cytochrome P450 TaCYP94‐A1 precisely regulates seed dormancy levels through plant hormone crosstalk, providing targets for improving resistance to pre‐harvest sprouting in wheat.
