The essential cofactor coenzyme A (CoASH) and its thioester derivatives (acyl-CoAs) have pivotal roles in cellular metabolism. However, the mechanism by which different acyl-CoAs are accurately partitioned into different subcellular compartments to support site-specific reactions, and the physiological impact of such compartmentalization, remain poorly understood. Here, we report an optimized liquid chromatography-mass spectrometry-based pan-chain acyl-CoA extraction and profiling method that enables a robust detection of 33 cellular and 23 mitochondrial acyl-CoAs from cultured human cells.

In recent years, there has been a rapid increase in the incidence of thyroid carcinoma (TC). Our study focuses on the regulatory effect of circular RNAs on metabolism of TC, aiming to provide new insights into the mechanisms of progression and a potential therapeutic target for TC. In this study, we identified high expression levels of circPSD3 in TC tissues through RNA sequencing.

Several genes in the mitochondria of angiosperms are interrupted by introns, and their posttranscriptional excision involves numerous nucleus-encoded auxiliary factors. Most of these factors are of eukaryotic origin, among them members of the pentatricopeptide-repeat (PPR) family of RNA-binding proteins. This family divides into the PLS and P classes, with PLS-class proteins typically participating in C-to-U mRNA editing and P-class members contributing to transcript stabilization and intron splicing.

Type 2 diabetes (T2D) is characterized by persistent and unresolved tissue inflammation caused by the infiltration and dysregulation of immune cells. Current therapeutics targeting inflammatory immune cells for T2D remain limited. In this study, we analyzed single cell RNA from metabolic organs in T2D, revealing increased macrophage accumulation and a pathogenic macrophage subpopulation defined as NOD-like receptor (NLR) family pyrin domain-containing 3 (NLRP3) inflammatory and metabolically activated macrophages.

The calcium ion (Ca) is a pivotal second messenger orchestrating diverse cellular functions, including metabolism, signaling, and apoptosis. Membrane contact sites (MCSs) are critical hubs for Ca exchange, enabling rapid and localized signaling across cell compartments. Well-characterized interfaces, such as those between the endoplasmic reticulum (ER) and mitochondria and ER-plasma membrane (PM), mediate Ca flux through specialized channels.
