Blocking Lysine Crotonylation and Aerobic Glycolysis as Targeting Strategy Against mpox Virus Replication

open access: yesAdvanced Science, EarlyView.
Wei et al. report that MPXV infection induces aerobic glycolysis, a process mediated by the viral protein I3 through lysine crotonylation at its K102 residue. The acetyltransferase MYST1 catalyzes the crotonylation of I3 to inhibit the ubiquitin‐mediated degradation of WDR26.

Bifurcate Regulation of Hematopoietic Homeostasis and Bone Osteogenesis by VHL‐HIF2α‐Controlled Adipocyte Function

open access: yesAdvanced Science, EarlyView.
The VHL‐HIF2α (VHL is Von Hippel‐Lindau) axis in adipocytes differentially regulates hematopoiesis and bone formation through stem cell factor (SCF) and chemerin, respectively. This hypoxia‐responsive pathway in adipocytes establishes a systemic signaling network with HSCs and MSCs to maintain tissue homeostasis, revealing a targetable axis for ...

A Tobacco Homolog of DCN1 is Involved in Cellular Reprogramming and in Developmental Transitions [PDF]

open access: yes, 2011
Plant proteomes show remarkable plasticity in reaction to environmental challenges and during developmental transitions. Some of this adaptability comes from ubiquitin-mediated protein destruction regulated by cullin-RING E3 ubiquitin ligases (CRLs ...

SV2B Promotes the Progression of TFE3‐Rearranged Renal Cell Carcinoma by Interacting with HERC2 to Impede the Degradation of NF‐κB Subunits

open access: yesAdvanced Science, EarlyView.
TFE3‐rearranged renal cell carcinoma (TFE3‐RCC) lacks clearly defined diagnostic and therapeutic targets. SV2B, a TFE3 target gene, promotes TFE3‐RCC progression by activating the NF‐κB pathway. Targeted inhibition with padsevonil or Withaferin A effectively suppresses tumor progression.

DCAF12 Ubiquitin Ligase Promotes Lung Cancer Metastasis by Modulating the TRiC/CCT Chaperonin Complex

open access: yesAdvanced Science, EarlyView.
This study elucidates how DCAF12 facilitates non‐degradative ubiquitination to stabilize TRiC/CCT, thereby enhancing the folding capacity of chaperonins. This mechanism promotes the maturation of cytoskeletal proteins and activates key oncogenic drivers, including YAP, STAT3, and mTOR, ultimately driving metastatic progression in lung cancer.

ARL3 Enhances ERα Stability via USP10 Deubiquitination to Promote Endocrine Resistance and Drive Mitochondrial Metabolic Reprogramming in HR+ Breast Cancer

open access: yesAdvanced Science, EarlyView.
This study identifies ADP‐ribosylation factor‐like protein 3 (ARL3) as a novel chaperone that stabilizes estrogen receptor α (ERα) in breast cancer. ARL3 promotes tumor growth by recruiting USP10 to remove ubiquitin chains from ERα, preventing its degradation.

TRIM56 Aggravates Cerebral Ischemia‐Reperfusion Injury via Inhibiting KLF4‐Activated Ferroptosis Signaling

open access: yesAdvanced Science, EarlyView.
This study reveals that the E3 ubiquitin ligase TRIM56 exacerbates neuronal ferroptosis and brain damage by mediating K48‐linked ubiquitination and degradation of KLF4, leading to suppression of the xCT/GSH/GPX4 axis. Targeting TRIM56 alleviates cerebral ischemia‐reperfusion injury in vivo and in vitro, highlighting its therapeutic potential.

TMEM131‐Mediated Soluble TRAIL Triggered Type II Alveolar Epithelial Cell Senescence in Radiation‐Induced Lung Injury

open access: yesAdvanced Science, EarlyView.
TMEM131 recruits the COPII complex to accelerate TRAIL transportation from endoplasmic reticulum to Golgi apparatus, and promotes soluble TRAIL secretion. TRAIL inhibits mitophagy and induces senescence through DR5 receptor in type II alveolar epithelial cells, ultimately driving radiation‐induced lung injury (RILI) progression.

Parkin uses the UPS to ship off dysfunctional mitochondria [PDF]

open access: yes, 2011
Parkin is a ubiquitin E3 ligase that is implicated in familial Parkinson disease (PD). Previous studies have established its role in mitophagy, a pathway whereby dysfunctional mitochondria are targeted for autophagic degradation.
