Epigenetic changes affect how genes are turned on and off or expressed, and thus help regulate how cells in different parts of the body use the same genetic code. Errors in the epigenetic process can not only lead to abnormal gene activity or inactivity, but can also influence alternative splicing (AS) and could cause human diseases. Understanding of how epigenetic defects can affect human health, especially for neurological disorders, could suggest targets for therapeutic interventions. For such a purpose, the Lesch-Nyhan disease (LND) has been selected as a valuable model to study the genetic-epigenetic interplay, especially to explore the epistasis between the housekeeping hypoxanthine phosphoribosyltransferase 1 (HPRT1) and β-amyloid precursor protein (APP) genes. This review is structured as follows: we begin with an overview about the monogenetic neurological disorders associated with epigenetic changes; next, the current knowledge on HPRT1 and APP genes is provided; then, the epistasis between HPRT1 and APP genes related to the neurobehavioral syndrome in LND is described; and finally, we present the construction of expression vectors to study intermolecular interactions between the hypoxanthine-guanine phosphoribosyltransferase (HGprt) enzyme and APP in LND.

However, while genetic mutations, dietary factors, and immune dysregulation are implicated in AD pathogenesis, the current therapeutic approaches are largely centered around acetylcholinesterase inhibitors (AChEIs). Nevertheless, this cholinergic hypothesis of AD is no longer satisfactory in describing this disease and has demonstrated a limited efficacy. Hence, new treatment approaches should be developed, and that requires us to view AD from a new perspective. Herein, in our review, we present the latest studies that discussed possible AD pathologies and pharmacotherapies. Additionally, we highlight that the emerging treatments that precisely targets brain regions associated with enhancing neuroplasticity have delivered promising results and seem to be more effective than older treatments.

Despite existing therapeutic strategies, including lifestyle interventions, pharmacological treatments, and surgical options, limitations such as poor adherence, side effects, and accessibility issues call attention to the need for novel solutions. Tetrahydrocannabivarin (THCV), a non-psychoactive cannabinoid derived from <i>Cannabis sativa</i>, has emerged as a promising agent to manage metabolic disorders. Unlike tetrahydrocannabinol (THC), THCV exhibits an antagonistic function on the CB1 receptor and a partial agonist function on the CB2 receptor, thus enabling appetite suppression, enhanced glucose regulation, and increased energy expenditure. Preclinical studies demonstrated that THCV improves insulin sensitivity, promotes glucose uptake, and restores insulin signaling in metabolic tissues. Additionally, THCV reduces lipid accumulation and improves the mitochondrial activity in adipocytes and hepatocytes, shown through both cell-based and animal research. Animal models further revealed THCV's potential to suppress appetite, prevent hepatosteatosis, and improve metabolic homeostasis. Preliminary human trials support these findings, thereby showing that THCV may modulate appetite and glycemic control, though larger-scale studies are necessary to confirm its clinical efficacy and safety. THCV's unique pharmacological profile positions it as a possible therapeutic candidate to address the multifaceted challenges of obesity and diabetes. Continued research should concentrate on optimizing formulations, undertaking well-designed clinical studies, and addressing regulatory hurdles to unlock its full potential.</p>","PeriodicalId":7732,"journal":{"name":"AIMS Neuroscience","volume":"12 1","pages":"32-43"},"PeriodicalIF":3.1,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12011981/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143959813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
