The E3 Ubiquitin Ligase ARIH1 Facilitates Colorectal Cancer Progression by Promoting Oxidative Phosphorylation via the Mitochondrial Translocation of K63‐Linked Ubiquitinated PHB1

open access: yesAdvanced Science, EarlyView.
The RBR E3 ubiquitin ligase ARIH1, which is upregulated in colorectal cancer cells, promotes cell growth and metastasis and correlates with an unfavorable CRC prognosis. Mechanistically, ARIH1 catalyzes K63‐linked ubiquitination of PHB1, enhancing the interaction between PHB1 and Akt.

Targeting GPX4 to Induce Ferroptosis Overcomes Chemoresistance Mediated by the PAX8‐AS1/GPX4 Axis in Intrahepatic Cholangiocarcinoma

open access: yesAdvanced Science, EarlyView.
PAX8‐AS1 drives chemoresistance in intrahepatic cholangiocarcinoma by activating NRF2‐mediated GPX4 transcription and stabilizing GPX4 mRNA via IGF2BP3. Targeting the PAX8‐AS1/GPX4 axis with a GPX4 inhibitor enhances the efficacy of gemcitabine and cisplatin in preclinical models, offering a promising strategy to overcome chemotherapy resistance in ...

The FGF13‐Caveolin‐1 Axis: A Key Player in the Pathogenesis of Doxorubicin‐ and D‐Galactose‐Induced Premature Cardiac Aging

open access: yesAdvanced Science, EarlyView.
The FGF13 level is significantly downregulated in premature aging murine hearts subject to D‐galactose and Doxorubicin. FGF13 overexpression and deficiency exacerbated and alleviated Doxorubicin/D‐galactose‐induced myocardial aging characteristics and functional impairment, respectively.

Identification and Application of a Novel Patulin Degrading Enzyme From Meyerozyma guilliermondii

open access: yesAdvanced Science, EarlyView.
Patulin (PAT), a hazardous mycotoxin, threatens human health. A novel yeast‐derived short‐chain dehydrogenase/reductase effectively degrades PAT into nontoxic ascladiol via catalytic triad activity. The biological detoxification process has no significant effect on the quality of fresh pear juice.

The MdHB7L–MdICE1L–MdHOS1 Module Fine‐Tunes Apple Cold Response via CBF‐Dependent and CBF‐Independent Pathways

open access: yesAdvanced Science, EarlyView.
In early cold response, MdICE1L utilizes MdHB7L as a cofactor to facilitate the transcriptional activation of MdCBFs, thereby activating cold signaling rapidly and strongly. Subsequently, MdICE1L is degraded by MdHOS1. Meanwhile, MdHB7L is released and accumulates.

HDAC6 and USP9X Control Glutamine Metabolism by Stabilizing GS to Promote Glioblastoma Tumorigenesis

open access: yesAdvanced Science, EarlyView.
Glioblastoma (GBM) growth relies on glutamine synthetase (GS), which is stabilized by histone deacetylase 6 (HDAC6) and deubiquitinated by ubiquitin‐specific peptidase 9, X‐linked (USP9X). HDAC6 promotes GS deacetylation, while USP9X removes its K48‐linked polyubiquitination, enhancing GS stability.

Trimerization of 1,2‐Diaminocyclohexane Catalyzed by a Metal–Organic Cage Tandem Catalyst with Dual Biomimetic Active Sites

open access: yesAdvanced Science, EarlyView.
Dual biomimetic active sites, i.e., mononuclear {ZnII(L)(H2O)} and dinuclear {L2ZnII(CHO2)(OH)ZnIIL2}, have been successfully intergrated into a metal–organic cage, Zn20‐MOC. These two different active sites in Zn20‐MOC catalyze different steps of cascade trimerization of 1,2‐diaminocyclohexane. The mononuclear {ZnII(L)(H2O)} site catalyzes the initial

Electrochemical‐Genetic Programming of Protein‐Based Magnetic Soft Robots for Active Drug Delivery

open access: yesAdvanced Science, EarlyView.
This manuscript presents a protein‐based soft robot for active drug delivery. Stimuli‐responsive protein is rationally designed and processed into the substrate of robots. Superparamagnetic Fe3O4 nanoparticles are patterned on the substrate using an electrochemical method, enabling the robot to respond to external physical fields.

PP2A Promotes the Symmetric Division of MUC1‐Dominant Cancer Stem‐Like Cells in Small Cell Lung Cancer

open access: yesAdvanced Science, EarlyView.
During the G2/M phase, mucin1 (MUC1) activates protein phosphatase 2A (PP2A), leading to reduced phosphorylation of protein kinase C ζ (PKCζ) and NUMB, which promotes symmetric division and expansion of cancer stem‐like cells (CSLCs), thereby driving tumorigenesis. Combined inhibition of the MUC1–PP2A axis using LB100/GO203 with etoposide restores PKCζ
