ANXA2+ Small Extracellular Vesicles Drive Chemoresistance in Anaplastic Thyroid Cancer by Promoting XRCC5 Lactylation and Enhancing Non‐Homologous End‐Joining Repair

Advanced Science, EarlyView.
ANXA2+ sEVs promote cisplatin resistance in ATC by stabilizing the SRC/LDHA interaction, increasing LDHA phosphorylation and activity, and lactate production. Elevated lactate levels promote KAT5‐mediated lactylation of XRCC5 at lysine 265, enhancing its binding to XRCC6.

Psychological Stress Associated Bile Acid Reprogramming Promotes Hepatocellular Carcinoma Progression

Advanced Science, EarlyView.
Depression is increasingly recognized as a risk factor for chronic diseases, yet its biological impact on cancer remains unclear. Using data from more than 490 000 participants across three international cohorts, we show that depression significantly increases the risk of liver cancer.

E3 ubiquitin ligases in signaling, disease, and therapeutics

Trends in Biochemical Sciences
The ubiquitin-proteasome system (UPS) is a central regulator of protein turnover and signaling, with E3 ubiquitin ligases conferring substrate specificity and chain-type control. Recent advances have revealed new mechanistic classes of E3 ligases and expanded our understanding of their roles in disease, including cancer, neurodegeneration, and immune ...

E3 ubiquitin ligases: key regulators of hormone signaling in plants [PDF]

, 2018
Ubiquitin-mediated control of protein stability is central to most aspects of plant hormone signaling. Attachment of ubiquitin to target proteins occurs via an enzymatic cascade with the final step being catalyzed by a family of enzymes known as E3 ...

Targeting GALNT7 Disrupts the TAZ O‐GalNAcylation Feedback Loop to Suppress Gallbladder Cancer Progression

Advanced Science, EarlyView.
Aberrant GALNT7‐mediated O‐GalNAcylation stabilizes TAZ to drive gallbladder cancer progression through a feed‐forward transcriptional loop. Structure‐based screening identifies Olaparib as a potent GALNT7 antagonist that disrupts this oncogenic axis, providing an immediate therapeutic strategy for this aggressive malignancy.

TRAF6 Lactylation in Glycolytic Macrophages Drives NF‐κB Signaling and M1 Polarization During Orthodontic Tooth Movement

Advanced Science, EarlyView.
Schematic diagram showing compressive stress triggers glycolytic reprogramming and lactate accumulation in macrophages. Lactate mediates TRAF6 lactylation at K171/K180 dual sites, which enhances its K63‐linked ubiquitination to activate the NF‑κB pathway and promote M1 polarization. This cascade drives orthodontic tooth movement (OTM) and alveolar bone

Targeted Degradation of STING by a Neutrophil Membrane‐Coated Nanoplatform Suppresses Microglial Pyroptosis After Subarachnoid Hemorrhage

Advanced Science, EarlyView.
MG1@NM‐Px serves as a microglia‐targeted STING‐degrading nanoplatform for subarachnoid hemorrhage. Following systemic administration, it crosses the blood–brain barrier and accumulates in activated microglia. STP1‐mediated STING ubiquitination and degradation suppress MAPK/inflammasome signaling, GSDME‐mediated pyroptosis, and IL‐1β release, revealing ...

A multi-lock inhibitory mechanism for fine-tuning enzyme activities of the HECT family E3 ligases

Nature Communications, 2019
HECT type E3 ligases are key regulators of cell growth and proliferation. Here the authors present the crystal structures of the Nedd4 family E3 ligase WWP1 in a closed and semi-open state and in combination with mutagenesis experiments identify a multi ...
