Abstract Aims The peptidyl‐prolyl cis/trans isomerase, Pin1, has a protective role in age‐related neurodegeneration by targeting different phosphorylation sites of tau and the key proteins required to produce Amyloid‐β, which are well‐known molecular signatures Alzheimer's disease (AD) neuropathology. direct interaction miR‐140‐5p with Pin1 mRNA its inhibitory protein translation been identified. main purpose this study was investigate miRNA‐140‐5p inhibition promoting expression therapeutic potential AntimiR‐140‐5p Aß oligomer (AßO)‐induced AD rat model. Methods Spatial learning memory were assessed Morris water maze. RT‐PCR, western blot, histological assays performed on hippocampal samples at various time points after treatments. enhanced ADAM10 expressions but little effect level. Results inhibitor markedly ameliorated spatial deficits induced AßO, concomitantly suppressed inflammatory mediators TNFα IL‐1β, three (thr231, ser396, ser404) as well increased phosphorylated Ser473‐Akt. Conclusion According our results, Antimir‐140‐mediated improvement AβO‐induced neuronal injury impairment rats may provide an appropriate rationale for evaluating inhibitors promising agent treatment AD.

MicroRNAs (miRNAs) are a class of small non-coding RNAs (ncRNAs) crucial for regulating gene expression at the post-transcriptional level. Recent evidence has shown that miRNAs also found in mitochondria, organelles produce energy cell. These mitochondrial miRNAs, known as mitomiRs, essential function and metabolism. MitomiRs can originate from nucleus, following traditional miRNA biogenesis pathways, or potentially DNA, allowing them to directly affect cellular dynamics within mitochondrion. While have been extensively investigated, involvement mitomiRs development neurodegenerative disorders like Alzheimer’s disease, Parkinson’s amyotrophic lateral sclerosis remain be elucidated. This review aims discuss findings on role such diseases their potential therapeutic targets, well highlight future research directions.

Parkinson’s disease (PD) is a severely debilitating neurodegenerative disease, affecting the motor system, leading to resting tremor, cogwheel rigidity, bradykinesia, walking and gait difficulties, postural instability. The severe loss of dopaminergic neurons in substantia nigra pars compacta causes striatal dopamine deficiency presence Lewy bodies indicates pathological hallmark PD. Although current treatment PD aims preserve or replace depletion brain, it notable that complete recovery from yet be achieved. Given complexity multisystem effects PD, underlying mechanisms pathogenesis are elucidated. advancement medical technologies has given some insights understanding mechanism potential with special interest role microRNAs (miRNAs) unravel pathophysiology In patients, was found brain tissue demonstrated dysregulated miRNAs expression profiles. Hence, dysregulation may contribute through modulation PD-associated gene protein expression. This review will discuss recent findings on dysregulation, regulation genes, neuron survival, α-synuclein-induced inflammation circulating miRNAs. next section this also provides an update uses as diagnostic biomarkers therapeutic tools for

MicroRNAs (miRNAs) are essential post-transcriptional gene regulators involved in various neuronal and non-neuronal cell functions play a key role pathological conditions. Numerous studies have demonstrated that miRNAs dysregulated major neurodegenerative diseases, such as Alzheimer’s disease, Parkinson’s multiple sclerosis, amyotrophic lateral or Huntington’s disease. Hence, the present work, we constructed comprehensive overview of individual microRNA alterations models above diseases. We also provided evidence promising biomarkers for prognostic diagnostic approaches. In addition, summarized data from literature about miRNA-based therapeutic applications via inhibiting promoting miRNA expression. finally identified overlapping signature across including miR-128, miR-140-5p, miR-206, miR-326, miR-155, associated with etiological cellular mechanisms. However, it remains to be established whether what extent therapies could safely exploited future effective symptomatic disease-modifying approaches different human disorders.

Alzheimer's disease (AD) is a neurodegenerative that primarily affects the elderly population and leading cause of dementia. Meanwhile, vascular hypothesis suggests damage occurs in early stages disease, to neurodegeneration hindered waste clearance, which turn triggers series events including accumulation amyloid plaques Tau protein tangles. Non-coding RNAs (ncRNAs), long noncoding (lncRNAs), microRNAs (miRNAs), circular (circRNAs), have been found be involved regulation AD. Furthermore, lncRNAs circRNAs can act as competitive endogenous inhibit miRNAs, their interactions form complex regulatory network. Exosomes, are extracellular vesicles (EVs), believed able transfer ncRNAs between cells, thus playing role brain by crossing blood-brain barrier (BBB). Exosomes part intercellular carrier system; therefore, utilizing exosomes deliver drugs recipient cells might not activate immune system, making it potential strategy treat central nervous system diseases.

MicroRNAs (miRNAs) are found in nerve terminals, synaptic vesicles, and synaptosomes, but it is unclear whether cytosolic miRNA populations differ Alzheimer's disease (AD) or if synaptosomal miRNAs affect AD synapse activity. To address these questions, we generated synaptosomes fractions from postmortem brains of unaffected control (UC) samples analyzed them using a global Affymetrix microarray platform. A group significantly differed (P < 0.0001) with high fold changes variance (+/- >200-fold) their expressions different comparisons: (1) UC synaptosome vs cytosol, (2) (3) cytosol (4) synaptosomes. MiRNAs data analysis revealed that some potential were consistently across sample groups. These differentially expressed further validated brains, APP transgenic (Tg2576), Tau (P301L), wild-type mice. The miR-501-3p, miR-502-3p, miR-877-5p identified as upregulated progression based on Braak stages. Gene Ontology Enrichment Ingenuity Pathway Analysis showed the involvement nervous system development, cell junction organization, assembly formation, function GABAergic synapse.
