(Submitter supplied) The canonical function of EZH2 is methylation of H3K27, although important non-canonical roles have recently been described. EZH2 mutation or deregulated expression has been conclusively demonstrated in the pathogenesis and response to treatment of acute myeloid leukemia (AML), thus making it an attractive therapeutic target. In this study, we therefore investigated whether inhibition of EZH2 might also improve the response of non-APL AML cells to ATRA-based therapy. more...

(Submitter supplied) All-trans-retinoic acid (ATRA) has been successfully used in therapy of acute promyelocytic leukemia (APL), a cytogenetically distinct subtype of acute myeloid leukemia (AML) but the response of non-APL AML cases to ATRA-based treatment has been poor. Here we show that, via epigenetic reprogramming, inhibitors of LSD1/KDM1 demethylase including tranylcypromine (TCP) unlocked the ATRA-driven therapeutic response in non-APL AML. more...

(Submitter supplied) We investigate the effects of GCN5 and LSD1 inhibition in acute myeloid leukemia. Therefore, we characterized gene expression changes by RNA-seq in AML cells (AML M2 cell line HL-60) following treatment with ATRA, MB3, GSK-LSD1 and their combinations.

(Submitter supplied) Epigenetic mechanisms including histone modifications play key roles in the pathogenesis of multiple myeloma (MM). We have previously shown that a histone H3 lysine 27 (H3K27) methyltransferase EZH2 and a H3K9 methyltransferase G9a are potential therapeutic targets in MM. Recent studies suggested that EZH2 and G9a cooperate to regulate gene expression. We thus aimed to evaluate the anti-tumor effect by dual targeting of EZH2 and G9a in MM. more...

(Submitter supplied) We report the use of RNAseq to determine the role of the TFEB transcription factor in all-trans retinoic acid induced differentiation of NB4 acute promyelocytic leukemia (APL) cells. We used lentiviral mediated shRNA approaches to functionally deplete TFEB in NB4 cells and compared the transcriptomes of wild type, scramble control shRNA and shTFEB knockdown cells treated with ethanol (control) versus all-trans retinoic acid for 72 hours.

(Submitter supplied) AE-expressing murine BM cells treated with all-trans retinoic acid (ATRA) in semi-solid methycellulose-based cultures show an increase in self-renewal capacity whilst treatment with a specific RARa agonist NRX195183 reduces their clonogenicity. Gene expression analysis was performed to further investigate the molecular mechanisms underlying these observations. Upregulated gene sets were identified in the ATRA-treated AE BM cells.

(Submitter supplied) G9a/GLP and Polycomb Repressive Complex 2 (PRC2) are two major epigenetic silencing machineries, which in particular methylate histone H3 on lysines 9 and 27 (H3K9 and H3K27), respectively. Although evidence of a crosstalk between H3K9 and H3K27 methylations has started to emerge, their actual interplay remains elusive. Here, we show that PRC2 and G9a/GLP interact physically and functionally. Moreover, combining different genome-wide approaches, we demonstrate that Ezh2 and G9a/GLP share an important number of common genomic targets, encoding developmental and neuronal regulators. more...

(Submitter supplied) Acute promyelocytic leukemia (APL) is a hematological disease characterized by a balanced reciprocal translocation that leads to the synthesis of the oncogenic fusion protein PML-RARα. APL is mainly managed by a differentiation therapy based on the administration of all-trans retinoic acid (ATRA) and arsenic trioxide (ATO). However, therapy resistance, differentiation syndrome, and relapses require the development of new low-toxicity therapies based on the induction of blasts differentiation. more...

(Submitter supplied) Preclinical studies have shown that combining the LSD1 inhibitor tranylcypromine (TCP) with all-trans retinoic acid (ATRA) induces differentiation and impairs survival in non-APL acute myeloid leukemia (AML). We conducted a Phase 1 clinical trial (NCT02273102) to evaluate the safety and preliminary activity of ATRA in combination with TCP in patients with relapsed/refractory AML and myelodysplasia (MDS). more...

(Submitter supplied) Acute myeloid leukemia (AML) is characterized by an accumulation of aberrant myeloid cells arrested at different stages of differentiation. Therapeutic approaches that prompt AML blasts to differentiate represent an attractive opportunity in the landscape of AML therapies, as they aim to induce terminal maturation and leukemia debulking without intensive cytotoxic treatments. In the present study, we investigate the involvement of HIF1a and HIF2a transcription factors in AML pathogenesis, and position HIF2a as a novel regulator of the AML differentiation block. more...
