Mitochondria play a crucial role in programmed cell death (PCD) in plants. In most cases of mitochondria-dependent PCD, cytochrome c (Cyt c) released from mitochondria due to the opening of mitochondrial permeability transition pore (MPTP) and the activation of caspase-like proteases. Here we describe the analytic methods of mitochondrial markers of PCD including mitochondria isolation, mitochondrial membrane permeability, mitochondrial inner membrane potential, Cytc release, ATP, and mitochondrial reactive oxygen species (ROS).

Mitochondrial quality control is crucial for the homeostasis of the mitochondrial network. The balance between mitophagy and biogenesis is needed to reduce cerebral ischemia-induced cell death. Ischemic preconditioning (IPC) represents an adaptation mechanism of CNS that increases tolerance to lethal cerebral ischemia.

Sarcopenia, the age-related decline in muscle mass and function, is a significant contributor to increased frailty and mortality in the elderly. Currently, no FDA-approved treatment exists for sarcopenia. Here, we identified norharmane (NR), a β-carboline alkaloid, as a potential therapeutic agent for mitigating muscle aging.

We have described a novel mitochondrial disorder caused by biallelic pathogenic variants in the methionyl-tRNA synthetase 2 gene (MARS2), now termed Combined oxidative phosphorylation deficiency 25 (COXPD25). This study focuses on the generation and characterization of induced pluripotent stem cells (iPSCs) from fibroblasts of a patient with COXPD25. The resulting iPSC line ISMMSi060-A, carries the compound heterozygous variants c.

Background: The roles of the Pink1/Parkin pathway and mitophagy in lung injury during heat stroke remain unclear. In this study, we investigated the role of Pink1/Parkin-mediated mitophagy in acute lung injury (ALI) in rats with exertional heat stroke (EHS).
Methods: Sixty Sprague Dawley rats were randomly divided into control (CON), control + Parkin overexpression (CON + Parkin), EHS, and EHS + Parkin overexpression (EHS + Parkin) groups.

Background: Muscle atrophy is associated with Type 2 diabetes mellitus, which reduces the quality of life and lacks effective treatment strategies. Previously, it was determined that human umbilical cord mesenchymal stromal cell (hucMSC)-derived exosomes (EXOs) ameliorate diabetes-induced muscle atrophy. However, the systemic application of EXOs is less selective for diseased tissues, which reduces their efficacy and safety associated with their nonspecific biological distribution in vivo.
