RUNX1‐Mediated Hypoxic Signaling Impairs Myogenesis and Promotes Fibrosis in Myopathies

Advanced Science, EarlyView.
Myofiber overgrowth was associated with reduced blood flow and a potential hypoxic state in broiler breast muscle, accompanied by increased RUNX1 expression. Elevated RUNX1 impaired myogenic regeneration, promoted fibrosis, and disrupted the signaling niche required for efficient muscle repair, contributing to pathological degeneration in Wooden Breast

A UBE3A‐UTX Proteostasis‐Epigenetic Axis Governs Hypothalamic Energy Homeostasis

Advanced Science, EarlyView.
Ubiquitin protein ligase E3A (UBE3A) regulates hypothalamic energy homeostasis and promotes degradation of the histone demethylase UTX (KDM6A). Neuronal UBE3A loss increases susceptibility to diet‐induced obesity and is accompanied by UTX accumulation, reduced histone H3 lysine 27 trimethylation, and altered endoplasmic reticulum stress‐responsive gene

Site‐Specific Protein Bioconjugation Through Cellular Incorporation of Noncanonical Amino Acids

Angewandte Chemie, EarlyView.
Genetic code expansion (GCE) enables site‐specific installation of noncanonical amino acids containing bioorthogonal conjugation handles, allowing precise, homogeneous protein modification. This review examines the principles of orthogonal translation, surveys the chemistries available for chemoselective labeling, and highlights emerging multi‐site ...

TIPIN Couples Epigenetic Rewiring to EGFR Stabilization and Lenvatinib Resistance in Liver Cancer

Advanced Science, EarlyView.
DNA hypomethylation elevates TIPIN expression in liver cancer. TIPIN competes with E3 ligase c‐Cbl for the EGFR intracellular domain, inhibiting EGFR ubiquitination and lysosomal degradation to sustain oncogenic EGFR‐ ERK signaling. High TIPIN confers lenvatinib resistance, while TIPIN depletion restores drug sensitivity in liver cancer. ABSTRACT Aims:

pH‐Driven Two‐Stage Conformational Switching Activates an Acid‐Responsive Chaperone

Angewandte Chemie, EarlyView.
AchC is an ATP‐independent, pH‐responsive chaperone. AchC functions as a molecular switch, sensing pH changes and undergoing a two‐stage conformational transition: C‐terminal extension (colored in yellow) loosening at mild pH 4.0–5.5 and monomerization at strong acidic pH 3.0.

Cardiac Endothelial Enhancer RNA Tek‐e1 Restores Microvascular Homeostasis After Myocardial Infarction

Advanced Science, EarlyView.
Hypoxia‐induced KDM5A downregulation establishes a distinct endothelial repair programme, increasing H3K4me3 at the Tek promoter and intronic enhancer, enabling ISL1 to coordinately activate Tek transcription and induce enhancer‐RNA Tek‐e1. This cis‐regulatory RNA is essential for additional Tek/TIE2 induction through R‐loop formation and reinforced ...

Matrix Stiffness Promotes Tumor Metastasis by Triggering Recycling Endosome‐Mediated YY1 Nuclear Translocation and Transcriptional Activity

Advanced Science, EarlyView.
In stiff extracellular matrix (ECM), integrin αVβ3 transduces mechanical cues of ECM stiffness to promote recycling endosome formation, creating a signaling platform for yin yang 1 (YY1)/p21‐activated kinase 4 (PAK4) binding, but not in soft ECM. Then, this triggers PAK4‐mediated YY1 phosphorylation at S118, subsequent YY1 nuclear translocation and ...

Recurrent Neurodevelopmental Disorder Associated With a Dominant‐Negative TOP2B H63Y Variant

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT We describe a 7 year‐old boy with severe neurodevelopmental disorder, medically‐refractory epileptic encephalopathy, hyperkinetic movement disorder, hypotonia, cerebral and cerebellar atrophy and hypomyelination who was found to have a heterozygous de novo TOP2B NM_001330700.2:c.187C>T, p.(His63Tyr) variant.
