Pancreatic Cancer‐Derived Extracellular Vesicles Enriched with miR‐223‐5p Promote Skeletal Muscle Wasting Associated with Cachexia

open access: yesAdvanced Science, EarlyView.
EVs and EV‐microRNAs (miRNAs) mediate PDAC‐skeletal muscle communication. miR‐223‐5p reduces METTL14 transcription by targeting MAFA, which subsequently decreases m6A methylation in skeletal muscles, ultimately leading to muscle wasting. This study highlights the absorption of miRNA in PDAC‐derived EVs by skeletal muscles and reveals a previously ...

A series of xanthenes inhibiting Rad6 function and Rad6-Rad18 interaction in the PCNA ubiquitination cascade

open access: yesiScience, 2022
Summary: Ubiquitination of proliferating cell nuclear antigen (PCNA) triggers pathways of DNA damage tolerance, including mutagenic translesion DNA synthesis, and comprises a cascade of reactions involving the E1 ubiquitin-activating enzyme Uba1, the E2 ...

Akkermansia Muciniphila Alleviates Severe Acute Pancreatitis via Amuc1409‐Ube2k‐Foxp3 Axis in Regulatory T Cells

open access: yesAdvanced Science, EarlyView.
Akkermansia depletion correlates with acute pancreatitis (AP) severity. A. muciniphila and its protein Amuc_1409 mitigate pancreatic/systemic inflammation by expanding Tregs and IL‐10. Mechanistically, Amuc_1409 binds Ube2k, inhibiting Foxp3 ubiquitination to stabilize Treg differentiation and IL‐10 production, countering SAP‐induced SIRS/CARS ...

ER‐phagy Activation by AMFR Attenuates Cardiac Fibrosis Post‐Myocardial Infarction via mTORC1 Pathway

open access: yesAdvanced Science, EarlyView.
By catalyzing FAM134B ubiquitination and activating ER‐phagy, AMFR alleviates progressive fibrosis and cardiac dysfunction by inhibiting the mTORC1 pathway. Consequently, these findings underscore the essential role of AMFR‐driven ER‐phagy in mitigating the progression of fibrotic responses, offering a potential therapeutic target for preventing heart ...

β‐Mangostin Attenuates TET2‐Mediated DNA Demethylation of Prkcg in the Prevention of Intervertebral Disc Degeneration

open access: yesAdvanced Science, EarlyView.
β‐Mangostin alleviates intervertebral disc degeneration through dual modulation of macrophage polarization and the TET2‐Prkcg axis in nucleus pulposus cells. Abstract Intervertebral disc degeneration (IDD) induced lower back pain is a main cause of disability, resulting in a substantial workforce loss worldwide and placing a substantial burden on the ...

The ubiquitin conjugating enzyme Ube2W regulates solubility of the Huntington's disease protein, huntingtin

open access: yesNeurobiology of Disease, 2018
Huntington's disease (HD) is caused by a CAG repeat expansion that encodes a polyglutamine (polyQ) expansion in the HD disease protein, huntingtin (HTT). PolyQ expansion promotes misfolding and aggregation of mutant HTT (mHTT) within neurons.

A conserved ubiquitin ligase of the nuclear envelope/endoplasmic reticulum that functions in both ER-associated and Mat a2 repressor degradation [PDF]

open access: yes, 2001
Substrate discrimination in the ubiquitin–proteasome system is believed to be dictated by specific combinations of ubiquitin–protein ligases (E3s) and ubiquitin-conjugating enzymes (E2s).

The Neglected Role of GSDMD C‐Terminal in Counteracting Type I Interferon Signaling

open access: yesAdvanced Science, EarlyView.
The C‐terminal domain of Gasdermin D (GSDMD‐CT) shows functions beyond pyroptosis. GSDMD‐CT negatively regulates IFN‐I signaling during viral infection by triggering autophagic degradation of RIG‐I and TBK1. GSDMD‐CT interacts with retinoic acid‐inducible gene‐I (RIG‐I) and tank‐binding kinase 1 (TBK1), leading to TRIM28‐mediated ubiquitination and ...

Determinants of chemoselectivity in ubiquitination by the J2 family of ubiquitin-conjugating enzymes

open access: yesThe EMBO Journal
AbstractUbiquitin-conjugating enzymes (E2) play a crucial role in the attachment of ubiquitin to proteins. Together with ubiquitin ligases (E3), they catalyze the transfer of ubiquitin (Ub) onto lysines with high chemoselectivity. A subfamily of E2s, including yeast Ubc6 and human Ube2J2, also mediates noncanonical modification of serines, but the ...
