Covalent fluorescent probes for 2‐arachidonoylglycerol metabolic pathways

British Journal of Pharmacology, EarlyView.
Abstract Covalent fluorescent probes have emerged as versatile chemical tools to visualise active enzymes in complex biological systems. When tailored for specific applications, ranging from activity‐based protein profiling for drug development to high spatiotemporal resolution imaging of enzymatic activities, these probes provide unique insights into ...

SCD2 Alleviates Diabetes‐Associated Cognitive Dysfunction by Improving Microglial Lipid Metabolism

Cell Proliferation, EarlyView.
This study reveals a novel mechanism of microglial metabolic dysfunction in diabetic cognitive impairment. Defective SCD2 disrupts monounsaturated fatty acid (MUFA) metabolism, triggering mitochondrial oxidative phosphorylation dysfunction and leading to abnormal lipid droplet accumulation (marked by PLIN2).

PLIN5 Protects Against Ang II‐Induced Podocyte Lipotoxicity by Interacting With FKBP8 and Preserving Lipid Droplet–Mitochondria Contact

Cell Proliferation, EarlyView.
PLIN5‐FKBP8 tethers lipid droplets to mitochondria to counteract Ang II‐induced lipotoxicity. ABSTRACT Chronic kidney disease (CKD) remains a major global health challenge. Angiotensin II (Ang II)‐induced lipotoxicity is an important contributor to podocyte injury.

The malate–aspartate shuttle supports thermogenic lipid mobilization in brown adipocytes

The FEBS Journal, EarlyView.
Brown fat cells burn lipids within their mitochondria to generate heat. This process involves two energy “shuttles,” one of which is naturally blocked during heat production. We found that the second shuttle (MASh) is not required to generate heat. However, when MASh is disabled, the fatty acids meant for fuel are instead converted back into stored fat.

Opposing roles of DGAT‐mediated lipid droplet biogenesis in the regulation of ferroptosis sensitivity

The FEBS Journal, EarlyView.
Ferroptosis is driven by unrestricted peroxidation of polyunsaturated fatty acyl (PUFA) chains in membrane phospholipids. In triple‐negative breast cancer cells, lipid droplets (LDs) sequester dietary PUFAs, limiting their incorporation into membrane phospholipids, preventing mitochondrial damage, and reducing lipid peroxidation and ferroptosis.

Disruption of iron metabolism resulting from Dmt1/Slc11a2 deficiency compromises Notch protein degradation and transcriptional activation

The FEBS Journal, EarlyView.
Divalent metal transporter 1 (Dmt1) maintains iron homeostasis and lysosomal proteostasis required for physiological Notch receptor–ligand signaling. Dmt1 loss lowers iron storage capacity (ferritin), increasing intracellular Fe2+, driving ROS and lipid peroxidation, and leading to lysosomal/mitochondrial dysfunction.
