Abstract Ischemic stroke is one of the major causes of long-term disability and mortality worldwide. It results from an interruption in the cerebral blood flow, triggering a cascade of detrimental events like oxidative stress, mitochondrial dysfunction, neuroinflammation, excitotoxicity, and apoptosis, causing neuronal injury and cellular death. Melatonin, a pleiotropic indoleamine produced by the pineal gland, has multifaceted neuroprotective effects on stroke pathophysiology. Interestingly, the serum melatonin levels are associated with peroxidation and antioxidant status, along with mortality score in patients with severe middle cerebral artery infarction. Melatonin exhibits strong antioxidant, anti-inflammatory, and anti-apoptotic properties and preserves More >

Abstract Background: Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related mortality worldwide. This study aimed to identify key genes involved in HCC development and elucidate their molecular mechanisms, with a particular focus on mitochondrial function and apoptosis. Methods: Differential expression analyses were performed across three datasets—The Cancer Genome Atlas (TCGA)-Liver Hepatocellular Carcinoma (LIHC), GSE36076, and GSE95698—to identify overlapping differentially expressed genes (DEGs). A prognostic risk model was then constructed. Cysteine/serine-rich nuclear protein 1 (CSRNP1) expression levels in HCC cell lines were assessed via western blot (WB) and quantitative reverse transcription polymerase chain reaction (qRT-PCR).… More > Graphic Abstract

Abstract Elevated homocysteine is a clinically relevant metabolic signal in chronic obstructive pulmonary disease (COPD). Higher circulating levels track with oxidative stress, endothelial dysfunction, mitochondrial impairment, and pulmonary vascular remodeling, rise with disease severity, and may contribute to the excess cardiovascular risk—although effect sizes and causality remain uncertain. This review centers on the homocysteine–carnitine relationship in COPD pathophysiology. Carnitine deficiency, prevalent in COPD, can worsen mitochondrial bioenergetics, promote accumulation of acyl intermediates, and reduce nitric oxide bioavailability via endothelial nitric oxide synthase uncoupling (eNOS). Conversely, restoring carnitine status in experimental and early clinical settings has been… More >

Abstract The pathogenesis of insulin resistance is influenced by environmental factors, genetic predispositions, and several medications. Various drugs used to manage multiple ailments have been shown to induce insulin resistance, which could lead to Type II Diabetes mellitus (T2DM). Central to drug-induced insulin resistance is mitochondrial dysfunction. Amongst disturbed pathways in drug-induced mitochondrial toxicity is mitophagy, a process that removes dysfunctional mitochondria through the lysosomal pathways to maintain mitochondrial quality. A balance must always be maintained between mitochondrial dynamics and mitophagy, as any alterations may contribute to the pathogenesis of metabolic diseases such as diabetes mellitus.… More >

Abstract Deuterium is a heavy isotope of hydrogen, with an extra neutron, endowing it with unique biophysical and biochemical properties compared to hydrogen. The ATPase pumps in the mitochondria depend upon proton motive force to catalyze the reaction that produces ATP. Deuterons disrupt the pumps, inducing excessive reactive oxygen species and decreased ATP synthesis. The aim of this review is to develop a theory that mitochondrial dysfunction due to deuterium overload, systemically, is a primary cause of Parkinson’s disease (PD). The gut microbes supply deuterium-depleted short chain fatty acids (SCFAs) to the colonocytes, particularly butyrate, and… More >

Abstract Benign prostatic hyperplasia (BPH) represents a prevalent etiology of lower urinary tract symptoms (LUTS) in the male population, clinically defined by a non-malignant proliferation of prostatic tissue. While BPH exhibits a high prevalence among older male populations globally, the precise underlying mechanisms contributing to its development remain incompletely elucidated. Mitochondria, essential organelles within eukaryotic cells, are critical for cellular bioenergetics, the regulation of reactive oxygen species (ROS) generation, and the modulation of cell death pathways. The maintenance of mitochondrial homeostasis involves a complex interplay of processes. By synthesizing previous literature, this review discusses mitochondrial homeostasis More >

Abstract Background: Multiple myeloma (MM) remains a formidable clinical challenge due to its high relapse rate and resistance to existing therapies. Estrogen-related receptor gamma (ERRγ), a nuclear receptor critical for cellular energy metabolism, has been implicated in various cancers. but its role in MM remains unclear. Methods: ERRγ expression was assessed using bioinformatics and RT-qPCR. Functional studies were conducted through siRNA-mediated ERRγ knockdown and treatment with the inverse agonist GSK5182 to examine their effects on MM cell proliferation and apoptosis. Results: ERRγ was significantly upregulated in the bone marrow of MM patients, correlating with advanced clinical stages… More > Graphic Abstract

Abstract Rotenone is a lipophilic herbicide extensively utilized in experimental neurodegenerative models because of its capacity to disrupt complex I of the mitochondrial electron transport chain. This inhibition results in reduced ATP synthesis, elevated reactive oxygen species (ROS) formation, and mitochondrial malfunction, which instigates oxidative stress and cellular damage, critical elements in neurodegenerative disorders like Parkinson’s disease (PD), amyotrophic lateral sclerosis (ALS), and Alzheimer’s disease (AD). In addition to causing direct neuronal injury, rotenone significantly contributes to the activation of glial cells, specifically microglia and astrocytes. Activated microglia assumes a proinflammatory (M1) phenotype, distinguished by the… More >

Abstract Mitochondria are central organelles in cellular metabolism, orchestrating energy production, biosynthetic pathways, and signaling networks. Nicotinamide adenine dinucleotide (NAD⁺) and its reduced form (NADH) are essential for mitochondrial metabolism, functioning both as redox coenzymes and as signaling agents that help regulate cellular balance. Thus, while its major role is in energy production, NAD⁺ is widely recognized as a metabolic cofactor and also serves as a substrate for various enzymes involved in cellular signaling, like sirtuins (SIRTs), poly (ADP-ribosyl) polymerases (PARPs), mono (ADP-ribosyl) transferases, and CD38. Sirtuins, a family of NAD⁺-dependent deacetylases, are critical in this regulatory network.… More >

Abstract Background: Acute Myeloid Leukemia (AML) is a highly aggressive clonal hematological malignancy with limited treatment options. This study aimed to evaluate the therapeutic potential of nigericin, a polyether ionophore derived from Streptomyces DASNCL-29, as a mitochondrial-targeted agent for AML treatment. Methods: Nigericin was isolated from Streptomyces DASNCL-29 and characterized via chromatography and NMR. Its cytotoxicity was tested in MOLM13 (sensitive and venetoclax-resistant) and HL60 (sensitive and cytarabine-resistant) cells using the MTT assay. Mitochondrial dysfunction was assessed by measuring reactive oxygen species (ROS), mitochondrial membrane potential (Δψm), and mitochondrial mass. Apoptosis was evaluated with Annexin V/PI assays… More > Graphic Abstract
