Project description:Based on previous work on the KDM histone demethylase family in AML, the transcription factor NFATC2 was identified as a regulatory target of KDM4A in MLL-AF9-rearrangement THP-1 cells. Our existing work examined the elements of the transcriptome regulated by NFATC2 in THP-1 cells and so, to further this work, we aimed to characterise the DNA-binding targets of NFATc2 in these cells. In this study, we used NFATc2 immunoprecipitation for ChIP-seq in untreated THP-1 cells, in order to determine these.

Project description:Knockdown of NFATC2 in AML cell lines using a lentiviral shRNA approach was shown to be detrimental to cell survival in vitro. We hypothesised that NFATC2 is essential for AML oncogenic signalling in these cells and its depletion would result in the perturbation of the affected pathways

Project description:The transcription factor Nfatc2 is a potent β-cell mitogen in mouse and human islets, however, the direct genomic targets that mediate the mitogenic effects have not been identified. We expressed a constitutively active form of Nfatc2, and the closely related Nfatc1, in human islets and identified ~5,600 differentially expressed genes. Nfatc2 binding sites in human islets were identified via ChIP-seq, yielding ~8,600 high-confidence peaks. By integrating gene expression changes induced by Nfatc2 with genomic binding sites for Nfatc2, we identified ~2,200 direct transcriptional targets of Nfatc2 in human islets. Direct targets that were induced by Nfatc2 were enriched for transcripts that regulate the cell cycle, and for motifs associated with the transcription factor FoxP1. We showed that islets from an endocrine-specific FoxP1, FoxP2 and FoxP4 triple-knockout mouse are less responsive to Nfatc2-induced β-cell proliferation, suggesting the FoxP family may work in concert with Nfatc2 to regulate β-cell proliferation. Nfatc2 induced β-cell proliferation in both mouse and human islets, whereas Nfatc1 does so only in human islets. Exploiting this species difference in Nfatc1-responsiveness, we identified ~250 direct transcriptional targets with similar transcriptional profiles. This gene set strongly enriches for cell cycle-associated transcripts, and includes the nuclear hormone receptor, Nr4a1. We show that deletion of Nr4a1 greatly reduces the capacity of Nfatc2 to induce β-cell proliferation, suggesting that much of the effect on Nfatc2 occurs through its induction of Nr4a1. Integration of ncRNA profiling, chromatin accessibility and Nfatc2 binding sites enabled us to identify key Nfatc2-dependent enhancer loci that mediate enhanced β-cell proliferation.

Project description:The hypomethylating agent 5-azacytidine (AZA) is the first-line induction therapy for AML patients unsuitable for intensive chemotherapy. The anti-tumor effect of AZA results in part from T-cell cytotoxic responses against MHC-I-associated peptides (MAPs) deriving from hypermethylated genomic regions such as cancer-testis antigens (CTAs), or endogenous retroelements (EREs). However, clear evidence supporting higher ERE MAPs presentation after AZA treatment in AML is lacking. Interestingly, we find that AZA-mediated DNMT2 inhibition leads to autophagy induction, which is responsible for mitigating ERE MAPs generation. To validate our findings, we examined the immunopeptidome of THP-1 cells treated with AZA combined with autophagy inhibitor, Spautin-1 or decitabine (DAC, non-DNMT2 inhibiting HMA) through a proteogenomic approach.

Project description:EVI1 is one of the famous poor prognostic markers for a chemotherapy-resistant acute myeloid leukemia (AML). To identify molecular targets on the surface of leukemia cells with EVI1high expression, we compared the gene expression profiles of several AML cell lines by DNA microarray To search for novel molecular targets in refractory myeloid leukemia with high EVI1 expression, we initially analyzed the gene expression profiles of 12 human myeloid cell lines. Four cell lines with chromosome 3q26 abnormalities (UCSD/AML1, HNT-34, Kasumi-3 and MOLM-1) expressed EVI1High, and eight myeloid cell lines without chromosome 3q26 abnormalities (HEL, HL-60, K052, THP-1, FKH-1, K051, NH and OIH-1) expressed low levels of EVI1 (EVI1Low)
