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

open access: yesAdvanced 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

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 ...

Functional and phylogenetic analysis of the ubiquitylation system in Caenorhabditis elegans: ubiquitin-conjugating enzymes, ubiquitin-activating enzymes, and ubiquitin-like proteins

open access: yesGenome Biology, 2001
BackgroundThe eukaryotic ubiquitin-conjugation system sets the turnover rate of many proteins and includes activating enzymes (E1s), conjugating enzymes (UBCs/E2s), and ubiquitin-protein ligases (E3s), which are responsible for activation, covalent ...

Loss of the ubiquitin conjugating enzyme UBE2E3 induces cellular senescence

open access: yesRedox Biology, 2018
Cellular senescence plays essential roles in tissue homeostasis as well as a host of diseases ranging from cancers to age-related neurodegeneration. Various molecular pathways can induce senescence and these different pathways dictate the phenotypic and metabolic changes that accompany the transition to, and maintenance of, the senescence state.

Ubiquitination‐Dependent LLGL2 Degradation Drives Colorectal Cancer Progression via THBS3 mRNA Stabilization

open access: yesAdvanced Science, EarlyView.
During the progression of CRC, MDM2, as an E3 ubiquitin ligase, promotes the degradation of the LLGL2 protein. Reduced expression of the LLGL2 protein leads to the loss of support for the CNOT1 protein, decreasing the degradation of THBS3 mRNA. The increased THBS3 further activates the PI3K‐Akt pathway, promoting the proliferation and metastasis of CRC.

Anti‐Inflammatory Mechanisms of Selenium Nanosheets in Ulcerative Colitis: Protein Corona, GP130 Interaction, and Transcriptomic Profile

open access: yesAdvanced Science, EarlyView.
SeNSs provide a biocompatible, anti‐inflammatory UC therapy. SeNSs form protein coronas enriched with AKT/PI3K/NF‐κB pathway proteins, suppress GP130 via hydrophobic interactions, and inhibit pro‐inflammatory cytokines. In DSS‐induced UC mice, SeNSs reduce inflammation, tissue damage, and disease activity by modulating cytokine, chemokine, and ...

Proteome analysis reveals ubiquitin-conjugating enzymes to be a new family of interferon-alpha-regulated genes.

open access: yesEuropean Journal of Biochemistry, 2000
Interferon (IFN)-alpha is a cytokine with antiviral, antiproliferative, and immunomodulatory properties, the functions of which are mediated via IFN-induced protein products.

Nephronectin (NPNT) is a Crucial Determinant of Idiopathic Pulmonary Fibrosis: Modulating Cellular Senescence via the ITGA3/YAP1 Signaling Axis

open access: yesAdvanced Science, EarlyView.
Through a comprehensive multi‐omics analysis, this study identifies a marked reduction in Nephronectin (NPNT) expression within fibrotic lung tissue. This reduction impairs the binding capability to the ITGA3 receptor, consequently causing YAP1 to persist in the cytoplasm, where it undergoes degradation.

Combinatorial targeting of G‐protein‐coupled bile acid receptor 1 and cysteinyl leukotriene receptor 1 reveals a mechanistic role for bile acids and leukotrienes in drug‐induced liver injury

open access: yesHepatology, EarlyView., 2022
CHIN117 is a dual cysteinyl leukotriene receptor 1 (CYSLTR1) antagonist and G‐protein‐coupled bile acid receptor 1 (GPBAR1) agonist. In the liver, GPBAR1 and CYSLTR1 are coexpressed by liver sinusoidal endothelial cells (LSECs), HSCs, circulating monocytes/macrophages, and liver resident macrophages (Kupffer cells).
