Ischemic Postconditioning Protects Aged Myocardium Against Ischemia/Reperfusion Injury by Regulating Mitochondrial Dynamics via piR‐4913

open access: yesAdvanced Science, EarlyView.
A tiny RNA tips the scales of cardiac injury in aging. piR‐4913 recruits OGT to Drp1 and drives its O‐GlcNAcylation at Thr604, promoting excessive mitochondrial fission that aggravates ischemia‐reperfusion injury. Ischemic postconditioning silences this pathway to restore mitochondrial balance and protect the aged myocardium, revealing piR‐4913 as a ...

NDFIP2 Suppresses Colorectal Cancer Metastasis Through DDX3X‐Dependent R‐Loop Remodeling and GNG13 Transcriptional Activation

open access: yesAdvanced Science, EarlyView.
NDFIP2 recruits NEDD4 to promote K48‐linked ubiquitination and proteasomal degradation of DDX3X, leading to R‐loop accumulation and CTCF‐dependent suppression of GNG13 transcription. Consequently, PI3K/AKT signaling, EMT, stemness, and colorectal cancer metastasis are inhibited.

Tip60‐Mediated USP22 Lactylation Drives Glutamine Metabolic Reprogramming via SLC25A5 in TNBC

open access: yesAdvanced Science, EarlyView.
Tip60‐mediated USP22 K134 lactylation, stabilizing SLC25A5 to enhance glutamine metabolism and α‐KG secretion. The secreted α‐KG drives GPR91‐dependent M2 macrophage polarization, promoting triple‐negative breast cancer progression. Targeting this axis synergizes with CB‐839, offering a promising therapeutic strategy for TNBC.

NUB1 Regulates Muscle Atrophy in Lung Cancer Cachexia via NF‐κB Signaling Pathway

open access: yesAdvanced Science, EarlyView.
ABSTRACT Cancer‐associated cachexia (CAC) is a devastating multifactorial syndrome characterized by progressive skeletal muscle atrophy. Its mechanisms remain incompletely clarified, with limited effective therapeutic targets. NUB1, a negative regulator of ubiquitin‐like proteins mediating protein degradation, has not been fully elucidated in CAC ...

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

open access: yesAdvanced 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
