Current strategies for managing the adverse effects of chemotherapy exhibit limited efficacy and have the potential to induce various detrimental side effects. In the realm of complications, cardiotoxicity poses a serious threat, ranking as the second major contributor to illness and death in individuals suffering cancer. It is linked to various cellular mechanisms such as oxidative stress, inflammation, apoptosis, autophagy, endoplasmic reticulum stress, and aberrant myocardial energy metabolism. Both in vivo and in vitro experiments confirm that ginsenosides undeniably present non-toxic and efficacious alternatives for addressing chemotherapy-induced side effects, including cardiotoxicity, neurotoxicity, nephrotoxicity, hepatotoxicity, immunotoxicity, and hematopoietic inhibition. Hence, there is a need to produce novel and potent drugs sourced from natural, non-toxic compounds to address the side effects induced by chemotherapy.

Despite advancements in conventional treatments - surgery, chemotherapy, and radiation therapy-substantial challenges persist, including debilitating long-term toxicities and emerging resistance to therapy. This review examines the multifaceted roles of non-coding RNAs (ncRNAs) - particularly long non-- coding RNAs (lncRNAs) and circular RNAs (circRNAs) - in pediatric medulloblastoma pathogenesis, diagnosis, and therapeutic targeting. NcRNAs exert robust regulatory effects on gene expression by modulating signaling pathways, acting as miRNA sponges, and controlling the expression of oncogenic or tumor-suppressive genes. In this study, we focus on notable examples of lncRNAs (e.g., HOTAIR, TP73-AS1) and circRNAs (e.g., circ-SKA3, circ_63706) implicated in fundamental oncogenic processes, such as cell proliferation, apoptosis, metastasis, and stem cell maintenance. We also discuss their subgroup-specific roles, emphasizing high-risk groups, such as Sonic Hedgehog (SHH) and Group 3 medulloblastomas. In parallel, we explore the potential of ncRNAs to serve as diagnostic/prognostic biomarkers, given their tissue-specific expression, stability, and detectability in biological fluids like the Cerebrospinal Fluid (CSF). Finally, we review emerging therapeutic strategies, including antisense oligonucleotides, RNA sponges, and CRISPR-based editing, aimed at disrupting oncogenic ncRNA functions or reinforcing tumor-suppressive pathways. While these strategies hold promise, major hurdles include functional redundancy, optimizing in vivo delivery, and mitigating off-target effects. By detailing these challenges and outlining future research directions, this review underscores the revolutionary potential of ncRNA-focused diagnostics and therapies for managing pediatric medulloblastomas, offering new paths for improving survival outcomes and quality of life in affected children.</p>","PeriodicalId":10984,"journal":{"name":"Current medicinal chemistry","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143970736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional treatments primarily address symptoms but fail to target underlying causes, prompting exploration of novel approaches like gene therapy. The TGF-β family, encompassing TGF-β1, TGF-β2, and TGF-β3, plays a critical role in cellular processes including proliferation, apoptosis, and migration, with its dysregulation strongly linked to cardiovascular diseases. In atherosclerosis, TGF-β influences key factors, such as macrophage cholesterol regulation, plaque stability, and vascular smooth muscle cell function, while also contributing to endothelial dysfunction- an early stage in disease development. Personalized medicine has highlighted the importance of tailoring therapies to genetic profiles, particularly regarding TGF-β pathway variations such as SNPs in TGF-β1 and TGFBR2, which could inform more precise interventions. Emerging technologies like CRISPR-Cas9 and RNA-based therapies enable targeted modulation of these genetic factors, offering new avenues to mitigate disease progression. CRISPR-Cas9 allows direct editing of gene loci linked to atherosclerosis, potentially correcting mutations or modulating expression levels, while RNA-based therapies, including siRNAs and antisense oligonucleotides, provide additional precision tools for addressing dysregulated genes. This review focuses on identifying key genes and additional molecular players involved in or regulated by the TGF-β pathway that may serve as precise targets for gene therapy intervention in atherosclerosis and related cardiovascular diseases. By targeting genes involved in cholesterol metabolism, inflammation, and endothelial function, gene therapy offers a targeted strategy to ameliorate the genetic drivers of these conditions. In summary, modulation of TGF-β signaling by gene therapy has the potential to revolutionize the treatment of atherosclerosis and other cardiovascular diseases while shedding light on the underlying genetic mechanisms of these disorders.</p>","PeriodicalId":10984,"journal":{"name":"Current medicinal chemistry","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143972502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

AD causes structural and functional alterations in the affected brain, including shrinkage of gray matter volume and disruptions in brain network connectivity.

Effective pain management in AD is challenged by the adverse effects of pain-relief medications and communication difficulties, especially as the disease progresses. Both non- and pharmacological interventions are currently used to alleviate pain in AD. Pharmacological options include opioids, nonsteroidal anti-inflammatory drugs, paracetamol/acetaminophen, and adjuvant pain relievers like antidepressants and antiepileptic medications, though these are not officially approved for pain relief in AD. Non-pharmacological strategies, such as exercise therapy, music therapy, Reiki, reflexology, and behavioral therapy, are preferred to prevent the side effects of medication. However, the use of these methods is limited due to a lack of high-quality research.

Using the DrugRep server, the hub genes obtained underwent a virtual screening with experimental drugs, and twelve experimental drugs were selected to execute the molecular docking by CB-Dock2. Finally, the interactions were displayed in BIOVIA software.</p><p><strong>Result: </strong>Our results showed that the main molecular alterations of pancreatic islets in T2D were enzyme binding, mitochondrial metabolism, transcription factors, etc. They were involved in glucose uptake, receptor insulin signaling, and secretion. The molecular docking showed that SRC, AKT1, CREBBP, and HSP90AA1 were therapeutic targets for DB02729, DB04877, DB07970, DB07789, and DB03373.</p><p><strong>Conclusion: </strong>We identified some alterations in the pancreas of patients with T2D, ten hub genes, and five experimental drugs that could potentially correct gene expression abnormalities. However, further studies are required to validate these results.</p>","PeriodicalId":10984,"journal":{"name":"Current medicinal chemistry","volume":" ","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143802698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
