Tubocapsenolide A Overcomes Oxaliplatin Resistance in Colorectal Cancer by Targeting PLK1 to Impair CEP55–ESCRT‐Associated Vesicular Damage Clearance

Advanced Science, EarlyView.
Oxaliplatin‐resistant colorectal cancer cells utilize a previously unappreciated PLK1‐CEP55‐ESCRT‐driven vesicular extrusion mechanism to clear L‐OHP‐induced cellular damage. The natural withanolide Tubocapsenolide A directly targets and inhibits PLK1 to disrupt this specific damage‐clearance machinery. This blockade induces severe nucleolar stress and

HECTD1 Directs HIF‐1α to Facilitate Intestinal Inflammation and Carcinogenesis via Promoting Th17 Differentiation and Glycolysis

Advanced Science, EarlyView.
HECTD1 emerges as an upstream amplifier of Th17 metabolic programming by promoting K63‐linked ubiquitination of IGF2BP3 and enhancing HIF‐1α translation. HIF‐1α reciprocally drives HECTD1 transcription, establishing a positive regulatory loop that sustains glycolysis and Th17 differentiation.

Donor‐Cell Senescence Redirects PINK1‐Marked Mitochondrial Cargo From Mitophagy to Microvesicle Transfer Through SUMO3‐Stabilized HSPA9

Advanced Science, EarlyView.
ABSTRACT Extracellular vesicle therapies have been developed for tissue repair, but how donor‐cell senescence reshapes vesicle‐mediated mitochondrial transfer remains unclear. Here, we show that senescent adipose‐derived stem cells (ADSCs) redirect damaged mitochondria into microvesicles (MVs), converting protective vesicles into pro‐degenerative ...

Astrocytic Ketogenesis Protects Central Nervous System Injury via CPT1A Stabilization and Epigenetic Regulation

Advanced Science, EarlyView.
A distinct astrocyte subpopulation, enriched at the lesion border, drives CNS repair through enhanced ketone body metabolism. This process promotes neuronal survival and axonal sparing via CPT1A stabilization and H3K9bhb‐dependent epigenetic reprogramming, positioning astrocytic ketogenesis as a promising therapeutic target for tissue regeneration ...

ALDH2 Suppresses Ferroptosis and Promotes Bortezomib Resistance in Multiple Myeloma Through the KEAP1‐NRF2 Feedback Loop

Advanced Science, EarlyView.
ALDH2, which is overexpressed in multiple myeloma, competitively binds KEAP1 to stabilize NRF2 by blocking its ubiquitin‐proteasomal degradation. Stabilized NRF2 translocates into the nucleus to upregulate the expression of GPX4. In parallel, NRF2 binds to the ALDH2 promoter to regulate its transcription, forming a positive feedback loop that represses
