NSP7 Molecular Degrader Attenuates Coronaviral Infection Through the β‐TrCP1/FBXO5 Axis

Advanced Science, EarlyView.
Host E3 ligase FBXO5 as a key regulator that promotes K48‐linked ubiquitination and proteasomal degradation of SARS‐CoV‐2 NSP7, thereby suppressing viral replication. NSP7 ubiquitination is co‐regulated by β‐TrCP1 and TAF1. Small molecule BC24877 disrupts β‐TrCP1‐mediated degradation of FBXO5, stabilizing FBXO5 and enhancing NSP7 clearance ...

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

Advanced 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 ...

Structural visualization of HECT-type E3 ligase Ufd4 accepting and transferring ubiquitin to form K29/K48-branched polyubiquitination

Nature Communications
The K29/K48-linked ubiquitination generated by the cooperative catalysis of E3 ligase Ufd4 and Ubr1 is an enhanced protein degradation signal, in which Ufd4 is responsible for introducing K29-linked ubiquitination to K48-linked ubiquitin chains to ...

Ubiquitination contributes to the regulation of GDP-mannose pyrophosphorylase B activity

Frontiers in Molecular Neuroscience
GDP-mannose pyrophosphorylase B (GMPPB) loss-of-function is associated with muscular dystrophy and variable additional neurological symptoms. GMPPB facilitates the catalytic conversion of mannose-1-phosphate and GTP to GDP-mannose, which serves as a ...

NDRG1‐Driven Lactate Accumulation Promotes Lung Adenocarcinoma Progression Through the Induction of an Immunosuppressive Microenvironment

Advanced Science, EarlyView.
NDRG1 drives lactate accumulation and histone lactylation in lung adenocarcinoma, promoting immunosuppression via M2 macrophage polarization and CD8⁺ T cell inhibition. High NDRG1 expression correlates with poor prognosis, an immunosuppressive microenvironment, and immunotherapy resistance.

Targeting IGF1R Overcomes Armored and Cold Tumor Microenvironment and Boosts Immune Checkpoint Blockade in Triple‐Negative Breast Cancer

Advanced Science, EarlyView.
IGF1R is highly expressed in the armored & cold tumors, and collagen mediates IGF1R at the transcriptional and post‐translational levels to promote TNBC cell invasion and immune escape and to stabilize its own structure by interacting with the collagen receptor DDR1.
