Hydrogen sulfide (HS) was once considered to have only toxic properties, until it was discovered to be an endogenous signaling molecule. The effects of HS are dose dependent, with lower concentrations being beneficial and higher concentrations, cytotoxic. This scenario is especially true for the effects of HS on mitochondrial function, where higher concentrations of the gasotransmitter inhibit the electron transport chain, and lower concentrations stimulate bioenergetics in multiple ways. Here we review the role of HS in mitochondrial function and its effects on cellular physiology.

Cardiovascular diseases (CVDs) are the leading cause of mortality among individuals with noncommunicable diseases worldwide. Obesity is associated with an increased risk of developing cardiovascular disease (CVD). Mitochondria are integral to the cardiovascular system, and it has been reported that mitochondrial transfer is associated with the pathogenesis of multiple CVDs and obesity.

Over the past few decades, microtubules have been targeted by various anticancer drugs, including paclitaxel and eribulin. Despite their promising effects, the development of drug resistance remains a challenge. We aimed to define a novel cell death mechanism that targets microtubules using eribulin and to assess its potential in overcoming eribulin resistance.

Triplophysa bombifrons, a species of bony fish localized in China, has largely been understudied genetically, with limited data available beyond its mitochondrial genome. This study introduces a chromosome-level genome assembly for T. bombifrons, achieved through the integration of PacBio long-read sequencing and Hi-C chromatin interaction mapping.

Background/aim: Silicosis, the most severe type of occupational pneumoconiosis, leads to diffuse pulmonary fibrosis without specific therapy. Ferroptosis is triggered by reactive oxygen species (ROS) and Fe overload-induced lipid peroxidation, which is involved in the progression of pulmonary fibrosis. As an important coenzyme in the process of aerobic respiration, Coenzyme Q10 (CoQ10) can enhance mitochondrial function and energy supply and reduce malondialdehyde (MDA) to limit the risk of fibrosis.

CD147 has the potential to serve as a specific target with therapeutic characteristics in several respiratory diseases. Studies have demonstrated that CD147 regulates levels of oxidative phosphorylation (OXPHOS) through the process of mitochondrial translocations. However, there is still limited insight in the distinct mechanism of CD147 in asthmatic macrophages.
