Dynamic acylome reveals metabolite driven modifications in Syntrophomonas wolfei

Frontiers in Microbiology, 2022
Syntrophomonas wolfei is an anaerobic syntrophic microbe that degrades short-chain fatty acids to acetate, hydrogen, and/or formate. This thermodynamically unfavorable process proceeds through a series of reactive acyl-Coenzyme A species (RACS). In other

S‐acylation: an orchestrator of the life cycle and function of membrane proteins

The FEBS Journal, 2023
S‐acylation is a covalent post‐translational modification of proteins with fatty acids, achieved by enzymatic attachment via a labile thioester bond. This modification allows for dynamic control of protein properties and functions in association with cell membranes. This lipid modification regulates a substantial portion of the human proteome and plays

HNRNPU K181 Lactylation Drives Cervical Cancer Growth by Upregulating PHGDH and Reprogramming Serine Metabolism

Advanced Science, EarlyView.
Lactate in cervical cancer induces HNRNPU K181 lactylation, opposed by NAA50‐mediated acetylation and suppressed by Pazopanib. This lactylation enhances HNRNPU binding to PHGDH pre‐mRNA exon 1, maintaining exon 1‐containing transcripts and mRNA stability, thereby activating serine metabolism.

A Lipid‐Conjugation Strategy for Intracellular Reactive Oxygen Species Control in Hepatic Cells

Angewandte Chemie, EarlyView.
A lipid conjugation strategy anchors a manganese Salen complex within phospholipid membranes, yielding stable, catalytically active liposomes. These lipid–metal assemblies efficiently degrade reactive oxygen species (ROS) and enable intracellular redox control in steatotic HepaRG cells, offering a precise route to biomimetic antioxidant design ...

Synthesis and Characterization of 2-Decenoic Acid Modified Chitosan for Infection Prevention and Tissue Engineering

Marine Drugs, 2021
Chitosan nanofiber membranes are recognized as functional antimicrobial materials, as they can effectively provide a barrier that guides tissue growth and supports healing. Methods to stabilize nanofibers in aqueous solutions include acylation with fatty

Technologies and Challenges in Proteomic Analysis of Protein S-acylation [PDF]

Journal of Proteomics & Bioinformatics, 2014
Protein S-acylation (also called palmitoylation) is a pervasive post-translational modification that plays critical roles in regulating protein trafficking, localization, stability, activity, and complex formation. The past decade has witnessed tremendous advances in the study of protein S-acylation, largely owing to the development of novel S ...

Unveiling Lactylation: A Novel Frontier in Cancer Stemness and Therapy

Advanced Science, EarlyView.
Tumor metabolism and epigenetic regulation are intrinsically linked. This review highlights lactylation as a pivotal bridge connecting these processes, acting as an active epigenetic effector in cancer stemness. We delineate how lactylation orchestrates the cancer stem cell landscape and evaluate its regulatory networks.

Non‐Dilute Synthesis of Macrodiolides and Macrotetrolides Enabled by Confinement Catalysis

Angewandte Chemie, EarlyView.
Confinement catalysis within a hexameric resorcin[4]arene capsule enables macrolactonization under non‐dilute conditions (up to 0.1 M), overcoming the limitations of high‐dilution protocols (0.1–10 mM). This strategy provides direct access to 18–32‐membered macrodiolides and 26–32‐membered macrotetrolides in one pot and unlocks previously inaccessible ...

Polyglutamine Tract Expansion Increases S-Nitrosylation of Huntingtin and Ataxin-1. [PDF]

PLoS ONE, 2016
Expansion of the polyglutamine (polyQ) tract in the huntingtin (Htt) protein causes Huntington's disease (HD), a fatal inherited movement disorder linked to neurodegeneration in the striatum and cortex.

Gut Microbiota, Immunity, and Metabolism in the Progression From Chronic Liver Disease to Hepatocellular Carcinoma

Advanced Science, EarlyView.
This review explains how chronic liver injury progresses toward hepatocellular carcinoma through interconnected changes in gut microbes, metabolism, immunity, fibrosis, and diet. It highlights microbial metabolites, bile‐acid signaling, immune dysfunction, and nutritional or microbiome‐based interventions as opportunities to identify risk earlier ...
