Due to the relatively low mutational burden in pediatric tumors, epigenetic dysregulation and differentiation blockade is a hallmark of oncogenesis in some childhood cancers. By targeting epigenetic regulators that maintain tumor cells in a primitive developmental state, epigenetic therapies may induce differentiation. The most well-studied and clinically advanced epigenetic-targeted therapies include azacitidine and decitabine, which inhibit DNA methylation through competitive inhibition of the enzymatic activity of the DNA methyltransferase family enzymes. These DNA hypomethylating agents are Food and Drug Administration (FDA) approved for hematologic malignancies. The discovery that DNA hypermethylation occurs in patients with isocitrate dehydrogenase (IDH) mutations has led to the development and FDA approval of IDH inhibitors for hematologic and solid tumors. Epigenetic dysregulation in pediatric tumors is also driven by changes in the \"histone code\" that either promote oncogene expression or repress tumor suppressors. Cancers whose chromatin landscape is characterized by such aberrant histone posttranslational modifications may be amenable to targeted therapies that inhibit the chromatin-modifying enzymes that read, write, and erase these histone modifications. Small molecules that inhibit the enzymatic activity of histone deacetylases, acetyltransferases, and methyltransferases have been approved for the treatment of some adult cancers, and these agents are currently under investigation in various pediatric tumors. Chromatin regulatory complexes can be hijacked by oncogenic fusion proteins that are produced by chromosomal translocations, which are common drivers in pediatric cancer. Small molecules that disrupt oncogenic fusion protein activity and their associated chromatin complexes have demonstrated remarkable promise, and this approach has become the standard treatment for a subset of leukemias driven by the PML-RARA oncogenic fusion protein. A deeper understanding of the mechanisms that drive epigenetic dysregulation in pediatric cancer may hold the key to future success in this field, as the landscape of druggable epigenetic targets is also expanding.</p>","PeriodicalId":10452,"journal":{"name":"Cold Spring Harbor perspectives in medicine","volume":" ","pages":""},"PeriodicalIF":7.8,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142853333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dopamine released from the substantia nigra is the underlying driving force keeping the basal ganglia network under proper equilibrium and, indeed, reduction of dopamine levels triggers basal ganglia dysfunction, setting the groundwork for several movement disorders. The canonical basal ganglia model has been instrumental for most of our current understanding of the normal and pathological functioning of this subcortical network. This model explains how cortical information flows through the basal ganglia nuclei back to the cortex by going through two pathways with opposing effects that together lead to the proper execution of a given movement. The basal ganglia model has paved the way for the standard clinical management of Parkinson's disease, where pharmacological and neurosurgical treatments in place collectively afford an impressive symptomatic alleviation. Although much of the model has remained, the canonical model has been enriched with new arrivals gathered from evidence provided in the last three decades.

As the retina is a neural tissue, it is in theory amenable to neuroprotective therapies that could help prolong cell survival or promote retinal function. Many neurotrophic factors have shown favorable results in preclinical animal models of neurodegenerative diseases, but unfortunately these findings have not yet translated into successful human clinical trials.

The resultant dependence of tumor cells on altered metabolism can induce sensitivity to specific metabolic perturbations that can be exploited for cancer therapy. Some cancers are caused by mutations that impart a novel function to metabolic enzymes, leading to the production of a tumor-promoting metabolite that is dispensable in normal cells, representing an ideal therapeutic target.
