Exposure to bisphenol S (BPS) is known adversely affect neuronal development. As pivotal components of polarization, axons and dendrites are indispensable structures within neurons, crucial for the maintenance nervous system function. Here, we investigated impact BPS exposure on axonal dendritic development both in vivo vitro. Our results revealed that during pregnancy lactation led a reduction complexity, density, length prefrontal cortex (PFC) offspring. Employing RNA sequencing technology elucidate underlying mechanisms damage induced by BPS, Kyoto Encyclopedia Genes Genomes (KEGG) analysis highlighted significant alteration oxidative phosphorylation (OXPHOS) pathway, essential mitochondrial Subsequent experiments demonstrate BPS-induced impairment function, including damaged morphology, decreased adenosine triphosphate (ATP) superoxide dismutase (SOD) levels, increased reactive oxygen species malondialdehyde (MDA). These alterations coincided with downregulated expression OXPHOS pathway-related genes (ATP6V1B1, ATP5K, NDUFC1, NDUFC2, NDUFA3, COX6B1) Myosin 19 (Myo19). Notably, Myo19 overexpression restored dysfunction alleviating inhibition pathway. Consequently, this amelioration was associated injury observed cultured neurons PFC.

Introduction The goal of this study is to explore the pharmacological potential amyloid-reducing vasodilator fasudil, a selective Ras homolog (Rho)-associated kinases (ROCK) inhibitor, in P301S tau transgenic mouse model (Line PS19) neurodegenerative tauopathy and Alzheimer's disease (AD). Methods We used LC-MS/MS, ELISA bioinformatic approaches investigate effect treatment with fasudil on brain proteomic profile PS19 mice. also explored efficacy reducing phosphorylation, beneficial and/or toxic effects its administration Results Proteomic profiling mice brains exposed revealed activation mitochondrial tricarboxylic acid (TCA) cycle blood-brain barrier (BBB) gap junction metabolic pathways. observed significant negative correlation between levels phosphorylated (pTau) at residue 396 both metabolite hydroxyfasudil. Conclusions Our results provide evidence proteins pathways related mitochondria BBB functions by support further development therapeutic for AD.

The efficacy of assisted reproductive technologies (ARTs) in older women remains constrained, largely due to an incomplete understanding the underlying pathophysiology. This review aims consolidate current knowledge on age-associated mitochondrial alterations and their implications for ovarian aging, with emphasis causes DNA (mtDNA) mutations, repair mechanisms, future therapeutic directions. Relevant articles published up 30 September 2024 were identified through a systematic search electronic databases. free radical theory proposes that reactive oxygen species (ROS) inflict damage mtDNA impair function essential ATP generation oocytes. Oocytes face prolonged pressure persisting five decades. MtDNA exhibits limited capacity double-strand break repair, heavily depending poly ADP-ribose polymerase 1 (PARP1)-mediated single-strand breaks. process depletes nicotinamide adenine dinucleotide (NAD⁺) ATP, creating detrimental cycle where continued further compromises oocyte functionality. Interventions interrupt this destructive may offer preventive benefits. In conclusion, cumulative burden mutations demands can lead depletion elevate risk aneuploidy, ultimately contributing ART failure women.

Alzheimer’s disease (AD) is the most common neurodegenerative disorder, accounting for approximately 70% of dementia cases worldwide. Patients gradually exhibit cognitive decline, such as memory loss, aphasia, and changes in personality behavior. Research has shown that mitochondrial dysfunction plays a critical role onset progression AD. Mitochondrial primarily leads to increased oxidative stress, imbalances dynamics, impaired mitophagy, genome abnormalities. These abnormalities are closely associated with amyloid-beta tau protein pathology, collectively accelerating process. This review summarizes mitochondria development AD, latest research progress, explores potential mitochondria-targeted therapeutic strategies Targeting mitochondria-related pathways may significantly improve quality life AD patients future.

Stroke is one of the leading causes morbidity and mortality worldwide. A main cause brain damage by stroke ischemia-reperfusion (IR) injury due to increased production reactive oxygen species (ROS) energy failure caused changes in mitochondrial metabolism. Ischemia a build-up succinate tissues NADH: ubiquinone oxidoreductase (complex I) activity that promote reverse electron transfer (RET), which portion electrons derived from are redirected ubiquinol along complex I reach NADH dehydrogenase module I, where matrix NAD+ converted excessive ROS produced. RET has been shown play role macrophage activation response bacterial infection, transport chain reorganization supply, carotid body adaptation levels. In addition stroke, deregulated RET-generated (RET-ROS) have implicated tissue during organ transplantation, whereas an RET-induced NAD+/NADH ratio decrease aging, age-related neurodegeneration, cancer. this review, we provide historical account roles oxidative pathogenesis ischemic summarize latest developments our understanding biology RET-associated pathological conditions, discuss new ways target cancer, neurodegenerative diseases modulating RET.

Purpose: Oxidative phosphorylation (OXPHOS) is an aerobic metabolic mechanism, and its dysfunction plays important role in the pathological changes of ischemic diseases. However, systematic studies on occurrence retinal detachment (RD) are lacking. Methods: Single-cell RNA sequencing (scRNA-seq) human retina was performed to detect various cells after RD. In this study, animal experiments were conducted explore OXPHOS activity addition, idebenone, a coenzyme Q10 (CoQ10) analog currently used treat Leber hereditary optic neuropathy (LHON), improve disorder experimental RD model. Results: ScRNA-seq revealed abnormal energy metabolism pathways Adenosine triphosphate (ATP) reactive oxygen species (ROS) main products OXPHOS, mouse model indicated that rise ROS levels may have greater impact photoreceptors early stage, whereas decreased ATP synthesis observed later stage; these threaten function morphology retina. Idebenone administered mice intragastrically, leading reduced stage post-RD improved which closely related maintenance mitochondrial morphology. Conclusions: leads photoreceptor degeneration RD, can be alleviated by improving function.
