Molecular mechanism of influenza A NS1-mediated TRIM25 recognition and inhibition [PDF]

, 2018
RIG-I is a viral RNA sensor that induces the production of type I interferon (IFN) in response to infection with a variety of viruses. Modification of RIG-I with K63-linked poly-ubiquitin chains, synthesised by TRIM25, is crucial for activation of the ...

Cardiomyocyte‐Enriched USP20 Ameliorates Pathological Cardiac Hypertrophy by Targeting STAT3 Deubiquitination

Advanced Science, EarlyView.
Cardiomyocyte‐enriched USP20 regulates the K63‐linked ubiquitination of STAT3, and the cardiomyocyte‐specific USP20‐STAT3‐CARM1 axis exerts a protective role in cardiac hypertrophy. Targeting USP20 through cardiac‐specific gene therapy presents a promising strategy for the treatment of cardiac hypertrophy.

Gelsolin's Protective Role in MASH through F‐Actin Regulation and P53 Degradation

Advanced Science, EarlyView.
Gelsolin (GSN) maintains liver metabolic homeostasis by promoting MDM2‐mediated P53 degradation and inhibiting F‐actin/Yes‐associated protein (YAP) overactivation. Loss of GSN impairs P53 degradation, increases lipid deposition, and enhances YAP‐driven fibrosis and inflammation in metabolic‐associated steatohepatitis.

Syntaphilin Ubiquitination Regulates Mitochondrial Dynamics and Tumor Cell Movements. [PDF]

, 2018
Syntaphilin (SNPH) inhibits the movement of mitochondria in tumor cells, preventing their accumulation at the cortical cytoskeleton and limiting the bioenergetics of cell motility and invasion. Although this may suppress metastasis, the regulation of the

Nuclear‐Localized BCKDK Facilitates Homologous Recombination Repair to Support Breast Cancer Progression and Therapy Resistance

Advanced Science, EarlyView.
Under DNA damage, tumor cells rely on efficient DNA repair for survival and therapy resistance. This study has demonstrated that BCKDK localizes to breast cancer cell nuclei, where it binds to and phosphorylates RNF8, thereby blocking ubiquitin‐mediated degradation of RAD51 and enhancing HRR. A selective BCKDK inhibitor synergizes with clinical agents,

Pyruvate Carboxylase in Macrophages Aggravates Atherosclerosis by Regulating Metabolism Reprogramming to Promote Inflammatory Responses Through the Hypoxia‐Inducible Factor‐1 Signaling Pathway

Advanced Science, EarlyView.
This study investigates the role of macrophage pyruvate carboxylase (PC) in atherosclerosis (AS) demonstrating that PC upregulation in macrophages promotes metabolism reprogramming to enhance inflammatory responses via the HIF‐1 signaling pathway.

METTL14‐Induced M6A Methylation Increases G6pc Biosynthesis, Hepatic Glucose Production and Metabolic Disorders in Obesity

Advanced Science, EarlyView.
It is shown that obesity is associated with increases in hepatic METTL14 and m6A methylation of G6pc transcript. YTHDF1 and YTHDF3 bind to m6A‐marked G6pc mRNA to increase its synthesis. Hepatocyte‐specific deletion of Mettl14 decreases G6pc m6A methylation, G6pc biosynthesis, and G6pc‐mediated gluconeogenesis, alleviating glucose metabolic defects in ...

Ethylene‐Activated E3 Ubiquitin Ligase MdEAEL1 Promotes Apple Fruit Softening by Facilitating the Dissociation of Transcriptional Repressor Complexes

Advanced Science, EarlyView.
Ethylene‐activated MdEAEL1 mediates the disassembly of the MdZFP3‐MdTPL4‐MdHDA19 transcriptional repression complex, upregulating the histone acetylation levels in the promoter regions of cell wall degradation‐related genes, consequently promoting softening during storage.

Multisite dependency of an E3 ligase controls monoubiquitylation-dependent cell fate decisions. [PDF]

, 2018
Metazoan development depends on tightly regulated gene expression programs that instruct progenitor cells to adopt specialized fates. Recent work found that posttranslational modifications, such as monoubiquitylation, can determine cell fate also ...
