Article Abstract

The mitochondrial permeability transition pore (mPTP) is a supramolecular entity in the inner mitochondrial membrane composed of various protein complexes, which is a critical component in maintaining mitochondrial function and cellular homeostasis. In this review, we provide a comprehensive summary of the current detection techniques for mPTP, including spectrophotometry, patch clamping, fluorescent probes, and flow cytometry, which have the potential to reveal the status of mPTP and its roles in degenerative diseases, inflammation, tumors and other diseases. Additionally, we discuss promising new methods to detect mPTP including enhancement in precision, high sensitivity, multi-parameter analysis, and technological integration. These advances highlight new possibilities of clinical diagnosis and treatment for mitochondria-related diseases.

Introduction: Endothelial-to-mesenchymal transition (EndoMT), cell death, and fibrosis are increasingly recognized as contributing factors to Alzheimer's disease (AD) pathology, but the underlying transcriptomic mechanisms remain poorly defined. This study aims to elucidate transcriptomic changes associated with EndoMT, diverse cell death pathways, and fibrosis in AD using the 3xTg-AD mouse model.

Methods: Using RNA-seq data and knowledge-based transcriptomic analysis on brain tissues from the 3xTg-AD mouse model of AD.

The present study investigated the effects of ultrasound-assisted L-lysine (Lys) in regulating mitochondrial function to enhance the color stability of porcine . The results indicated that the meat treated with ultrasound-assisted Lys showed higher * and * values, and lower * and * values. Simultaneously, the myoglobin (Fe) content significantly increased ( < 0.

Gap junctions (GJs) are critical structures for cardiac electrical signal conduction and synchronized contraction. Their fundamental components are transmembrane proteins from the connexin (Cx) family, which assemble into hexameric channels to form intercellular ion-permeable pathways, ensuring efficient electrical transmission and coordinated contraction between cardiac cells. Connexin 43 (Cx43), the most abundant connexin in the heart, serves as the primary constituent of ventricular gap junctions.

Epigallocatechin-3-gallate (EGCG), the main catechin in green tea, is associated with antidiabetic and anti-obesity effects, although its acute hepatic actions remain unclear. We investigated short-term effects of EGCG (10-500 μm) using isolated perfused rat livers and complementary assays in mitochondrial, microsomal, and cytosolic fractions. EGCG markedly inhibited gluconeogenesis from lactate (up to 52%), glycerol (33%), and alanine (47%), while it stimulated glycolysis, glycogenolysis, and oleic acid oxidation (+42% total ketone bodies).

Shiga toxin (Stx) is a virulence factor produced by serotype 1 and Stx-producing (STEC). It causes severe renal damage, leading to hemolytic uremic syndrome (HUS). The main target organ of Stx, the kidney, plays a role in maintaining water homeostasis in the body by increasing an osmotic gradient from the cortex to the medulla.
