Journal, Epigenetic controller: Celastrol inhibits lung cancer growth by triggering histone acetylation and acting synergically with HDAC inhibitors. (Pubmed Central) - Nov 9, 2022 In addition to upregulating H4K16 acetylation (H4K16ac), celastrol regulates H3K4 tri-methylation and H3S10 phosphorylation. Celastrol treatment significantly enhanced the suppressive effects of HDACi on lung cancer cell allografts in mice, with significant H4K16ac upregulation, indicating that a combination of celastrol and HDACi is a potential novel therapeutic approach for patients with lung cancer.

Inhibition of the Menin-MLL1 Interaction in MLL-Rearranged Primary Mixed-Phenotype Acute Leukemia Samples Promotes Leukemic Differentiation (ENMCC - Hall D) - Nov 4, 2022 - Abstract #ASH2022ASH_5953; Here we investigated potential application of the Menin-MLL inhibitor SNDX-5613 in MLL/AF4 MPAL infants who presented with the bilineage B/Myeloid phenotype...These myeloid data are consistent with observations of differentiation syndrome as an on-target effect in current clinical trials while the phenotypic changes in the lymphoid cells are new findings. Together, these data strongly suggests that MLL-r MPAL patients could benefit from the inclusion of the Menin-MLL1 inhibitors into their treatment regimens.

Although the cell surface expression of CD26 was relatively low or not detected on 5 MM cell lines (KMS26, KMS27, KMS28, KMS11, RPMI8226), cultured alone, the increased expression in CD26 levels of MM cells was detectable within 24 hr of the treatment with HDAC1i; FK228, HDAC3i; BG45, MS-275, RG2833 or HDAC6i; nexturastat A, tubastatin A, ACY-1215 as well as broad HDACi; LBH-589, SAHA by flow cytometry... HDACi not only shows anti-MM activity itself but sensitizes MM cells with CD26 antigen loss to CD26mAb via c-Myc/Sp1-mediated CD26 induction and augments its cytotoxicity.

Orthogonal Proteogenomic Approaches Identify the Druggable PA2G4-MYC Axis in 3q26 AML (ENMCC - 353-355) - Nov 4, 2022 - Abstract #ASH2022ASH_1675; We focused on the compounds with pan (AR-42, belinostat) or selective (entinostat) HDAC inhibitory properties...We translated these results in a “N-of-1” clinical trial proposing entinostat in association with azacytidine to patients with relapse/refractory 3q26 AML based on a compassionate use program for this regimen...This effect was not observed in patients treated with cytarabine...These data support the evidence that PA2G4 is a mediator of Evi1-Myc axis in AML. In conclusion, our work positions PA2G4 at the crosstalk of the Evi1-Myc leukemogenic signal for developing new therapeutics and, at this interesting time, urges upfront HDACi-based combination therapies in patients with 3q26 AML.

Epigenetic Resistance to Menin-MLL1 Inhibition Is Driven By Loss of the Non-Canonical Polycomb Repressive Complex 1.1 in NUP98-Rearranged AML (ENMCC - 343-345) - Nov 4, 2022 - Abstract #ASH2022ASH_1334; Menin-MLL1 inhibition using a small molecule VTP50469 simultaneously represses pro-leukemogenic genes and upregulates markers of myeloid differentiation...In summary, these results demonstrate that the NUP98-fusion-Menin-MLL complex and PRC1.1 dynamically compete for transcriptional control of developmentally regulated, stem-cell associated genes. Loss of PRC1.1 may promote NUP98-fusion protein-driven leukemogenesis and mediates resistance to Menin-MLL1 inhibition by failing to epigenetically silence genes that are essential for maintaining an undifferentiated, stem cell-like state.
