    Journal:  Inhibition of HDAC1 and 3 in the Presence of Systemic Inflammation Reduces Retinal Degeneration in a Model of Dry Age-Related Macular Degeneration. (Pubmed Central) -  Apr 12, 2024   
    Mice were treated with a selective HDAC class I inhibitor, MS-275, and retinal structure [optical coherence tomography (OCT)], function (electroretinography), and molecular changes quantitative real-time polymerase chain reaction (RT-qPCR, Western Blot) were assessed...In addition, HDAC inhibition in CIA + NaIO3 treated mice resulted in reduced cytokine production. These findings are highly innovative and provide additional support to the therapeutic potential of HDAC inhibitors for dry AMD treatment.

    Journal, IO biomarker:  Mechanisms of mesothelial cell response to viral infections: HDAC1-3 inhibition blocks poly(I:C)-induced type I interferon response and modulates the mesenchymal/inflammatory phenotype. (Pubmed Central) -  Mar 17, 2024   
    A quantitative proteomic analysis of MCs treated with MS-275, an HDAC1-3 inhibitor, unveiled altered expression of several proteins, including inflammatory cytokines/chemokines and interferon-stimulated genes (ISGs)...Collectively, our findings underline the significance of viral infections in acquiring a mesenchymal-like phenotype by MCs and the potential consequences of virus-associated peritonitis episodes for PD patients. The observed promotion of MMT reversal and interferon response inhibition by an HDAC1-3 inhibitor, albeit without a general impact on inflammatory cytokine production, has translational implications deserving further analysis.

    We previously showed, using the KPC (Kras LSL G12D/+; p53 r172H/+; Pdx1-Cre) mouse model of pancreatic cancer (PDAC), that sequential treatment with the DNA hypomethylating agent (HMA) decitabine (DAC) followed by aPD-1 initially enhanced anti-tumor effects, yet tumors developed resistance linked to a unique M2-polarized Chil3+ myeloid subtype...We then evaluated four different HDAC inhibitors with reported immunomodulatory effects and non-overlapping HDAC isoform specificities: Romidepsin (RM), Domatinostat (DM), Pracinostat (PR) and Entinostat (EN)...Our findings identify a functionally immune suppressive HMA specific myeloid effect. The addition of a second epigenetic agent enhances the therapeutic efficacy resulting in prolonged survival and reverses the suppressive myeloid cell related effects of DAC + aPD1.

    Menin drives oncogenesis in Ewing sarcoma cells by activating transcription of key metastatic factors (Room 31 - Upper Level - Convention Center) -  Mar 5, 2024 - Abstract #AACR2024AACR_8849;    
    To determine if genes altered in MEN1-KO cells were dependent on the role of Menin in Menin/MLL methyltransferase complexes, we analyzed transcriptomes of EwS cells that had been exposed to the Menin/MLL interaction inhibitor, VTP-50469...Finally, we found that Menin and EWS::FLI1 co-immunoprecipitate in EwS nuclear extracts suggesting that they may exist in complex with one another at sites of shared gene regulation. Taken together, these data indicate that Menin promotes EwS metastasis and that this is achieved by its function as a scaffolding protein that augments the transcriptional activity of EWS::FLI1 at intragenic enhancers of pro-metastasis genes.

    Anchored IL-12 synergizes with an epigenetic modulator to promote immune remodeling and overcome anti-PD1-refractory murine tumors (Section 4) -  Mar 5, 2024 - Abstract #AACR2024AACR_7010;    
    Significant decrease in CD4+ Tregs and increased CD8/Treg ratio were also observed. Ongoing functional studies, proteomic and immune cell analysis at the tumor site, tdLN, and periphery, including single cell transcriptomics and epigenetic studies, will allow for a deeper understanding of the synergistic effect of mANK-101 with the epigenetic modulator Entinostat.Conclusions Collectively, these findings form a rationale for the clinical combination of intralesional delivery of ANK-101 with entinostat for patients with ICB-refractory malignancies, including colorectal and HPV16neg head and neck cancers.

    From tumor progression to therapeutic control: Combinatorial targeting of immune vulnerabilities in TNBC (Section 3) -  Mar 5, 2024 - Abstract #AACR2024AACR_6902;    
    Preliminary data has revealed that immune-competent mammary tumor-bearing MMTV-PyMT transgenic mice have slowed tumor progression following sequential combination of a microtubule poison (paclitaxel; PTX) to enhance tumor immunogenicity, plus a macrophage-depleting/reprogramming agent such as a colony-stimulating factor 1 receptor blocking antibody (?CSF1R), and undergo primary tumor regression in 60% of transgenic mice when an ICI targeting PD-1 is applied (3x therapy) by a CD8+ T cell-dependent mechanism...Using a class 1 benzamide histone deacetylase (HDAC) inhibitor (e.g., entinostat) sequentially added to PTX/?CSF1R/?PD-1 therapy (4x) resulted in primary tumor stasis in 100% of mice, and significantly enhanced overall survival, in two transgenic mouse models of breast cancer (MMTV-PyMT and C3-(1)-TAg)...Adoptive serum transfer (AST) from 4x-treated MMTV-PyMT mice into either 3x-treated or untreated MMTV-PyMT mice elicited tumor stasis and control. These preclinical studies indicate the complexity of myeloid, B cell and T cell interactions that are co-opted by tumors, and identify novel paths to therapeutic tumor control by targeting vulnerable immune communication programs.

    Selective HDAC3 inhibition e-sensitizes PARPi-resistant ovarian cancer cells to olaparib (Section 24) -  Mar 5, 2024 - Abstract #AACR2024AACR_6880;    
    Interestingly, BRD3308 alone reduced colony formation in the ID8_OR cells, but not in the ID8 cells. In conclusion, selective HDAC3 inhibition in combination with olaparib may be an effective therapy in the treatment of acquired PARPi resistant ovarian cancers.

    Novel combination therapies to overcome non-genetic/adaptive menin inhibitor resistance in AML with MLL1r or mtNPM1 (Ballroom 6 B - Upper Level - Convention Center) -  Mar 5, 2024 - Abstract #AACR2024AACR_3342;    
    In vivo treatment with FHD-286 and OTX015 or SNDX-5613 significantly reduced the AML burden in mice bearing OCI-AML3-MITR xenografts. These findings underscore preclinical activity of epigenetically-targeted agent-based combinations and highlight their promise in overcoming MI resistance in AML with MLL1r or mtNPM1.

    HDAC3 sustains resistance to hypofractionated radiotherapy in fusion positve rhabdomyosarcoma cells (Section 28) -  Mar 5, 2024 - Abstract #AACR2024AACR_2682;    
    Recently, we reported that MS-275, a Class I and IV HDACi, in combination with RT affected cell survival, reduced colony formation ability, increased DNA damage repair inhibition and reactive oxygen species formation in FP-RMS cells...The new HDAC3i is highly specific in targeting FP-RMS cell growth in vitro while no effects have been observed in normal cells such as myoblasts and lung fibroblast. Moreover, the drug treatment in combination with radiotherapy phenotypically and molecularly recapitulated what observed in HDAC3 depleted cells.The study has been founded by Italian Association for Cancer Research (AIRC) to FM.

    Deciphering the mechanism of the menin-MLL complex dependency in HCC (Section 23) -  Mar 5, 2024 - Abstract #AACR2024AACR_2658;    
    Moreover, treatment of HCC cell lines (HLF, PLC/PRF5, HepG2) with recently developed menin inhibitor SNDX-5613 (revumenib) revealed a dose-dependent reduction in cell proliferation...Integration of our genomics data revealed a list of 30 genes, which are downregulated upon menin inhibition in both HLF and PLC/PRF5 cells (FC?1.5) and the direct targets of the menin-MLL complex in HLF cells, suggesting their potential role in HCC cell survival. Altogether, we anticipate that menin and ASH2L serve as promising targets and represent an appealing therapeutic strategy for HCC treatment.
