Multifunctional Hydroxyapatite Coated with Gallium Liquid Metal‐Based Silver Nanoparticles for Infection Prevention and Bone Regeneration

Advanced Functional Materials, EarlyView.
A multifunctional hydroxyapatite (HAp) coating integrated with silver‐gallium liquid metal nanoparticles (HAp‐Ag‐GaNPs) exhibits dual antibacterial and osteogenic properties. It effectively inhibits Gram‐positive and Gram‐negative bacteria, including resistant strains, while enhancing bone regeneration.

Double Cross‐Linked Hydrogel for Intra‐articular Injection as Modality for Macrophages Metabolic Reprogramming and Therapy of Rheumatoid Arthritis

Advanced Functional Materials, EarlyView.
A hydrogel for intra‐articular injection for the treatment of rheumatoid arthritis (RA) is formulated and comprehensively studied. After administration, the hydrogel induces a metabolic reprogramming of immunometabolism of macrophages to trigger fatty acid oxidation subsequently inducing polarization of anti‐inflammatory M2 macrophages. This results in

The Role of Pyruvate Dehydrogenase Kinase in Diabetes and Obesity [PDF]

Diabetes & Metabolism Journal, 2014
The pyruvate dehydrogenase complex (PDC) is an emerging target for the treatment of metabolic syndrome. To maintain a steady-state concentration of adenosine triphosphate during the feed-fast cycle, cells require efficient utilization of fatty acid and ...

3D Microtumors Representing Ovarian Cancer Minimal Residual Disease Respond to the Fatty Acid Oxidation Inhibitor Perhexiline

Advanced Healthcare Materials, EarlyView.
Minimal residual disease (MRD) leads to cancer relapse and poor survival in ovarian cancer. The lack of representative 3D models limits therapy development. The microfluidics‐based high throughput 3D microtumor platform described here generates clinically‐relevant MRD models. The 3D microtumors recapitulate the molecular signatures of MRD from patients.

Epipolythiodioxopiperazine‐Based Natural Products: Building Blocks, Biosynthesis and Biological Activities

ChemBioChem, Volume 23, Issue 23, December 5, 2022., 2022
Housing sulfur: Certain fungi produce diketopiperazine compounds with a transannular sulfur bridge. These so‐called epipolythiodioxopiperzines are toxic by non‐specifically interacting with intracellular proteins and contribute to fungal pathogenicity. Producer strains serve as bio‐pesticides but also question safety of food fermentation.

Metabolic checkpoint of ferroptosis resistance

Molecular & Cellular Oncology, 2021
The metabolic checkpoint of ferroptosis remains obscure. We find that glucose favors system xc− inhibitor-induced ferroptosis by activating pyruvate oxidation, thereby promoting fatty acid synthesis and subsequent lipid peroxidation.

Short‐Chain Fatty Acids Modulate Anti‐ROR1 CAR T‐Cell Function and Exhaustion in an Intestinal Adenocarcinoma‐on‐Chip Model

Advanced Healthcare Materials, EarlyView.
Short‐chain fatty acids modulate anti‐ROR1 chimeric antigen receptor (CAR) T‐cell function in an intestinal adenocarcinoma‐on‐chip model. Butyrate and propionate reduce cytotoxicity, cytokine release, and infiltration by inducing a regulatory T‐cell phenotype and T‐cell exhaustion via histone deacetylase inhibition.

Effects of pyruvate administration on infarct volume and neurological deficits following permanent focal cerebral ischemia in rats [PDF]

Brain Research 990(1-2): 1-7 (2003), 2007
Recent experimental evidences indicate that pyruvate, the final metabolite of glycolysis, has a remarkable protective effect against different types of brain injury. The purpose of this study was to assess the neuroprotective effect and the neurological outcome after pyruvate administration in a model of ischemic stroke induced by permanent middle ...

Development of Itaconate Polymers Microparticles for Intracellular Regulation of Pro‐Inflammatory Macrophage Activation

Advanced Healthcare Materials, EarlyView.
This study develops itaconate‐based polymer microparticles (IA‐MPs) for macrophage‐targeted intracellular delivery, overcoming the limitations of traditional itaconate administration. IA‐MPs achieve controlled release through phagocytosis, reducing pro‐inflammatory cytokine expression and reprogramming macrophage metabolism toward glycolysis.

Initial Experience of Metabolic Imaging with Hyperpolarized [1-13C]pyruvate MRI in Kidney Transplant Patients [PDF]

BACKGROUND: Kidney transplant is the treatment of choice for patients with end-stage renal disease. Early detection of allograft injury is important to delay or prevent irreversible damage. PURPOSE: To investigate the feasibility of hyperpolarized (HP) [1-13C]pyruvate MRI for assessing kidney allograft metabolism. SUBJECTS: 6 participants (mean age, 45.
