BACKGROUND: Multiple sclerosis is a chronic neurodegenerative autoimmune disease characterized by the presence of foci inflammation and demyelination in central nervous system. The initiation pathological processes multiple caused complex interaction genetic factors, unfavorable environmental factors epigenetic influences. Progressive neurological symptoms axonal conduction disorders, death neurodestruction lead to significant decreased patients’ quality life disability. search for new markers improve diagnostic therapeutic methods, including taking into account background interactions, an urgent task. AIM: work was aimed study changes DNMT1 mRNA expression patients with different duration, analyze methylation promoter, compare level homocysteine content blood, polymorphic variants genes coding key folate cycle enzymes. MATERIALS AND METHODS: peripheral mononuclear blood cells assessed reversed transcription followed polymerase chain reaction. Fluorescent reaction methyl-sensitive analysis high-resolution melting curves used promoter. determined chemiluminescence immunoassay. real-time genotyping polymorphism genes; fluorescent probes LNA modifications were discriminate alleles. RESULTS: It has been shown that patients, those at onset disease, significantly lower than control group. No relationship found between decrease promoter methylation. Strong positive combined effects genotypes MTR A2756G MTHFR C677T on have shown. These findings suggest genetically features metabolism may contribute disruption regulation sclerosis. CONCLUSIONS: obtained results indicate promise research identifying causing Studying mechanisms contribution pathogenesis could be one possible ways approaches.

Aging is characterized, amongst other features, by a complex process of cellular senescence involving both innate and adaptive immunity, called immunosenescence associated to inflammaging, low-grade chronic inflammation. Both processes fuel each partially explain increasing incidence cancers, infections, age-related autoimmunity, vascular disease as well reduced response vaccination. Multiple sclerosis (MS) lifelong disease, for which considerable progress in disease-modifying therapies (DMTs) management has improved long-term survival. However, disability progression, with age duration, remains. Neurologists are now involved caring elderly MS patients, comorbidities. the immune system therefore relevant implications pathogenesis, DMTs risks mediated these treatments. We propose review current evidence regarding markers molecular mechanisms their relevance understanding pathogenesis. will focus on changes auto-immune diseases, such systemic lupus erythematosus rheumatoid arthritis. The consequences pathology, interaction intrinsic aging central nervous resident cells be discussed. Finally, impact evolution safety efficacy presented.

Background: Substance use disorder (SUD) is closely associated with epigenetic modifications that significantly impact mental health outcomes. Alcohol and drug misuse induce widespread changes in the epigenome transcriptome of central nervous system, disrupting critical processes such as reward signaling emotional regulation. These alterations regulation gene expression often persist even after substance cessation, potentially contributing to onset or worsening psychiatric conditions, including schizophrenia, depression, stress, anxiety. Summary: This review delves into key mechanisms underlying SUD its comorbid disorders, a focus on DNA methylation, histone modifications, noncoding RNA Additionally, it examines influence environmental biological factors evaluates emerging epigenetic-based therapeutic strategies aimed at treating related conditions. Key Messages: Gaining deeper understanding driving disorders crucial for development effective interventions. highlights potential pharmacological mitigate societal personal burdens linked complications.

The complex and multidimensional landscape of type 2 diabetes mellitus (T2D) is a major global concern. Despite several years extensive research, the precise underlying causes T2D remain elusive, but evidence suggests that it influenced by myriad interconnected risk factors such as epigenetics, genetics, gut microbiome, environmental factors, organelle stress, dietary habits. number influencing pathogenesis increasing day which worsens scenario; meanwhile, interconnections shoot up frame. By gaining deeper insights into contributing we may pave way for development personalized medicine, could unlock more impactful treatment pathways individuals with T2D. This review summarizes state knowledge about pathogenesis, focusing on interplay between various their implications future therapeutic strategies. Understanding these lead to tailored treatments targeting specific inform prevention efforts population level, ultimately improving outcomes reducing its burden globally.

This narrative review examines the relationship between dopamine-related genetic polymorphisms, personality traits, and athletic success. Advances in sports genetics have identified specific single nucleotide polymorphisms (SNPs) genes linked to traits crucial for performance, such as motivation, cognitive function, emotional resilience. clarifies how variations can influence predisposition through dopaminergic pathways environmental interactions. Key findings reveal associations SNPs enhanced performance various sports. For example, COMT Val158Met rs4680 BDNF Val66Met rs6265 are associated with that could benefit increased focus, stress resilience conscientiousness, especially martial arts. DRD3 rs167771 is higher agreeableness, benefiting teamwork like football. synthesis underscores multidimensional role of shaping ability advocates integrating profiling into personalized training optimize well-being. However, research gaps remain, including need standardized protocols exploring gene–environment interactions diverse populations. Future studies should focus on epigenetic factors inform tailored interventions enhance both physical psychological aspects performance. By bridging genetics, psychology, exercise science, this paves way innovative optimization strategies.

Driven by genetic and environmental factors, aging is a physiological process responsible for age-related degenerative changes in the body, cognitive decline, impaired overall wellbeing. Notably, premature as well emergence of progeroid syndromes have posed concerns regarding chronic health conditions comorbidities population. Accelerated telomere attrition also implicated metabolic dysfunction development disorders. Impaired homeostasis arises secondary to increases synthesis free radicals, decreased oxidative capacity, antioxidant defense, disrupted energy metabolism. In particular, several cellular molecular mechanisms been identified decipher influence on diseases. These include defective DNA repair, attrition, epigenetic alterations, dysregulation nutrient-sensing pathways. The role pathogenesis diseases has largely attributed pro-inflammatory states that promote shortening, mutations telomerase reverse transcriptase, alteration, stress, mitochondrial dysfunctions. Nonetheless, therapeutic interventions focus restoring length telomeres may treatment approaches restore enzyme activity, alternative lengthening telomeres, counter decrease concentration cytokines. Given significance robust potential delaying diseases, this review aimed explore underlying assimilating evidence from both human animal studies.
