Special Issue Information

Dear Colleagues,

Mitochondria are one of the most important organelles that mediate cellular homeostasis. Mitochondria are the major source of ROS (reactive oxygen species) production. Oxidative stress is often characterized by the excessive ROS production, which causes several cellular alterations including mitochondrial dysfunction. Accumulating evidence suggests that oxidative stress and mitochondrial dysfunctions play a major role in the pathogenesis of various chronic diseases in peripheral tissues such as the lung (e.g., COPD, fibrosis, asthma), kidney (e.g., chronic kidney disease), and other vital organs. The usage of antioxidants in treating various chronic diseases is well known and widely studied across the scientific community. Recent advances in targeted therapeutics (specifically mitochondrial therapeutics) have helped to understand the key role played by mitochondria in health and diseases. Mitochondrial-based theranostics (therapy and diagnostics) are of immense interest and are ever-growing in recent years. This Special Issue is aimed to understand and update the recent advancements in the area of “mitochondrial dysfunction and oxidative stress” in various chronic diseases. We look forward to receiving your contributions.

Introduction: The mitochondrial function of circulating peripheral blood mononuclear cells (PBMCs) is an interesting new approach to cardiac diseases. Thus, PBMC’s mitochondrial respiration decreases in relation to heart failure severity. However, no data are available on heart-transplanted patients (Htx). Population and Methods: We determined PBMCs mitochondrial respiration by high-resolution respirometry (Oroboros Instruments) and superoxide anion production using electron paramagnetic resonance (Bruker-Biospin) in 20 healthy subjects and 20 matched Htx and investigated clinical, biological, echocardiographic, coronarography and biopsy characteristics. Results: PBMCs mitochondrial respiratory chain complex II respiration was decreased in Htx (4.69 ± 0.84 vs. 7.69 ± 1.00 pmol/s/million cell in controls and Htx patients, respectively; p = 0.007) and complex IV respiration was increased (24.58 ± 2.57 vs. 15.68 ± 1.67 pmol/s/million cell; p = 0.0035). Superoxide anion production was also increased in Htx (1.47 ± 0.10 vs. 1.15 ± 0.10 µmol/min; p = 0.041). The leucocyte-to-lymphocyte ratio was increased in Htx, whom complex II correlated with leucocyte number (r = 0.51, p = 0.02) and with the left ventricular posterior wall peak early diastolic myocardial velocity (r = −0.62, p = 0.005). Complex IV was increased in the two patients with acute rejection and correlated negatively with Htx’s isovolumetric relation time (r = −0.45, p = 0.045). Discussion: Although presenting with normal systolic function, Htx demonstrated abnormal PBMC’s mitochondrial respiration. Unlike immunosuppressive therapies, subclinical diastolic dysfunction might be involved in these changes. Additionally, lymphopenia might reduce complex II, and acute rejection enhances complex IV respirations. Conclusion: PBMC’s mitochondrial respiration appears modified in Htx, potentially linked to cellular shift, mild diastolic dysfunction and/or acute rejection. Full article

Mitochondria are semiautonomous doubly membraned intracellular components of cells. The organelle comprises of an external membrane, followed by coiled structures within the membrane called cristae, which are further surrounded by the matrix spaces followed by the space between the external and internal membrane of the organelle. A typical eukaryotic cell contains thousands of mitochondria within it, which make up 25% of the cytoplasm present in the cell. The organelle acts as a common point for the metabolism of glucose, lipids, and glutamine. Mitochondria chiefly regulate oxidative phosphorylation-mediated aerobic respiration and the TCA cycle and generate energy in the form of ATP to fulfil the cellular energy needs. The organelle possesses a unique supercoiled doubly stranded mitochondrial DNA (mtDNA) which encodes several proteins, including rRNA and tRNA crucial for the transport of electrons, oxidative phosphorylation, and initiating genetic repair processors. Defects in the components of mitochondria act as the principal factor for several chronic cellular diseases. The dysfunction of mitochondria can cause a malfunction in the TCA cycle and cause the leakage of the electron respiratory chain, leading to an increase in reactive oxygen species and the signaling of aberrant oncogenic and tumor suppressor proteins, which further alter the pathways involved in metabolism, disrupt redox balance, and induce endurance towards apoptosis and several treatments which play a major role in developing several chronic metabolic conditions. The current review presents the knowledge on the aspects of mitochondrial dysfunction and its role in cancer, diabetes mellitus, infections, and obesity. Full article
