GBM poses significant challenges for targeted therapies due to its intra- and inter-tumoral heterogeneity, a highly immunosuppressive microenvironment, diffuse infiltration into normal brain parenchyma, protection by the blood-brain barrier and acquisition of therapeutic resistance. Recent studies have implicated epigenetic modifiers as key players driving tumorigenesis, resistance, and progression of GBM. While the vast majority of GBM research on epigenetic modifiers thus far has focused predominantly on elucidating the functional roles and targeting of DNA methyltransferases and histone deacetylases, emerging evidence indicates that histone acetyltransferases (HATs) also play a key role in mediating plasticity and therapeutic resistance in GBM. Here, we will provide an overview of HATs, their dual roles and functions in cancer as both tumor suppressors and oncogenes and focus specifically on their implications in GBM resistance. We also discuss the technical challenges in developing selective HAT inhibitors and highlight their promise as potential anti-cancer therapeutics for treating intractable cancers such as GBM.</div></div>","PeriodicalId":9506,"journal":{"name":"Cancer letters","volume":"604 ","pages":"Article 217269"},"PeriodicalIF":9.1,"publicationDate":"2024-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142342206","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The liposomes co-loaded with veliparib and 2HG exhibited favorable stability, slow kinetics of drug release, and targeted delivery to the tumor. Furthermore, the veliparib/2HG liposomes demonstrated enhanced anti-tumor activity in both PARPi-resistant BRCA mutant cancer and BRCA wildtype cancer by synergistically enhancing the defect in DNA repair.

LAIT has been shown to induce systemic antitumor immune responses in pre-clinical studies and clinical trials, eradicating both treated local tumors and untreated distant metastases. In this study, we used LAIT to treat breast tumors in a mouse model and investigated the effects of LAIT on tumor-infiltrating γδT cells using single-cell RNA sequencing (scRNAseq). We characterized the γδT cells from tumors in control, PTT, GC, and LAIT (PTT + GC) groups, by identifying six distinct subtypes: activated, cytotoxic, cycling cytotoxic, IFN-enriched, antigen-presenting, and IL17-producing γδT cells. Differential gene expression analysis revealed that LAIT significantly upregulated genes associated with T cell activation, leukocyte adhesion, and interferon signaling in treated tumor tissues while downregulating genes involved in protein folding and stress responses. LAIT also uniquely increased the proportion of IL17-producing γδT cells, which correlated with prolonged survival in breast cancer patients, as analyzed using TCGA data. Furthermore, the transcriptomic profiles of γδT cells in LAIT-treated tumors closely resembled those in immune checkpoint inhibitor (ICI)-treated patients, suggesting potential synergistic effects.
