Effect of knockdown of Nol10 on gene expression in murine leukemia cells expressing NUP98::DDX10

Project description:NUP98 rearrangements associated with acute myeloid leukemia and myelodysplastic syndromes generate NUP98-fusion proteins. One such fusion protein, NUP98::DDX10, contains the putative RNA helicase DDX10. The molecular mechanism by which NUP98::DDX10 induces leukemia is not well understood. Here, we show that 24 amino acids within the DDX10 moiety of NUP98::DDX10 are crucial for cell immortalization and leukemogenesis. NOL10, nucleolar protein 10, interacts with the 24 amino acids, and NOL10 is a critical dependency of NUP98::DDX10 leukemia development. Studies in a mouse model of NUP98::DDX10 leukemia showed that loss of Nol10 impaired disease progression and improved survival. We also identified a novel function of NOL10 in that it acts cooperatively with NUP98::DDX10 to regulate serine biosynthesis pathways and stabilize ATF4 mRNA. Collectively, these findings suggest that NOL10 is a critical regulator of NUP98::DDX10 leukemia, and that targeting NOL10 (or the serine synthesis pathway regulated by NOL10) may be an effective therapeutic approach.

Transcription profiling of mouse bone marrow cells expressing NUP98/HHEX or NUP98/HOXA9 a new oncogenic fusion with acute myeloid leukemia

Project description:We have cloned and characterized a fusion gene NUP98/HHEX1 resulting from t(7;10) from a patient with acute myeloid leukemia (AML). As NUP98/HHEX acts as an aberrant transcriptional activator, putative targets were searched upon transient expression of the fusion in primary murine bone marrow cells. Experiment Overall Design: Murine bone marrow cells were transduced with a retrovirus (MSCV-IRES-GFP, MIG) expressing either NUP98/HHEX or NUP98/HOXA9 (or the empty vector), mRNA was isolated after 72h. Each experiment was performed in triplicates.

CDK6 is an essential direct transcriptional target of NUP98-fusion-protein-driven acute myeloid leukemia

Project description:Fusion proteins involving Nucleoporin 98 (NUP98) are recurrently found in Acute Myeloid Leukemia (AML) with poor prognosis. Lack of mechanistic insight into NUP98-fusion-dependent oncogenic transformation has precluded the identification of efficient targeting strategies. We reasoned that shared transcriptional programs of direct NUP98-fusion-protein-mediated gene control converge on actionable targets. To study the transcriptional regulation mediated by NUP98 fusion proteins we developed mouse models for regulatable expression of NUP98/NSD1, NUP98/JARID1A and NUP98/DDX10. Integration of transcriptional changes after oncogene shutdown in vivo with ChIP-seq data identified a common core of direct NUP98-fusion target genes in AML. Among the direct targets of all NUP98-fusions, the CDK6 (cyclin-dependent kinase 6) gene was highly expressed in mouse and human AML samples. CDK6 loss severely attenuated NUP98-fusion-driven leukemogenesis, and NUP98-fusion AML was hypersensitive to pharmacologic CDK6 inhibition in vitro and in vivo. These findings identify CDK6 as a conserved, critical direct target of NUP98-fusion proteins, proposing approved CDK4/CDK6 inhibitors as a rationale treatment option for AML patients with NUP98-fusions.

Ddx10 functions as a positive regulator of somatic cell reprogramming

Project description:RNA-binding proteins (RBPs) function in all steps of cellular RNA metabolism. Here, we find that Ddx10 gain-of-function promotes but loss-of-function impedes somatic cell reprogramming. Ddx10 loss-of-function results in significantly abnormal expression of innate immune response genes at the late stage of reprogramming. Knockdown of interferon transcription factor Irf1 or its downstream targets, Igtp and Tgtp2, respectively, obviously inhibited reprogramming. This study revealed that Ddx10 regulated reprogramming through modulating innate immune network.

Affymetrix SNP array data for NUP98 rearranged acute leukemias

Project description:We assessed lineage involvement by NUP98 translocations in myelodysplastic syndromes (MDS), acute myeloid leukemia (AML), and T-cell acute lymphoblastic leukemia (T-ALL). Single cell analysis by FICTION (Fluorescence Immunophenotype and Interphase Cytogenetics as a Tool for Investigation of Neoplasms) showed that NUP98-translocations with various partners, i.e. NSD1, DDX10, RAP1GDS1, and LNP1, always affected a CD34+/CD133+ hematopoietic precursor. Interestingly, in MDS/AML myelomonocytes, erythroid cells, B- and T- lymphocytes belonged to the abnormal clone, while in T-ALL only CD7+/CD3+ cells were involved. The partner did not appear to play a major role in determining the leukemia phenotype as shown in AML and T-ALL with the same NUP98-RAP1GDS1 fusion. Additional hits, namely mutations of FLT3 and CEBPA in MDS/AML and mutation of NOTCH1 plus MYB duplication in T-ALL, were identified in leukemias with, respectively, myeloid or T-lymphoid phenotype. Affymetrix SNP arrays were performed according to the manufacturer's directions on DNA extracted from cryopreserved diagnostic bone marrow or peripheral blood samples. Copy number and Copy neutral LOH analysis of with Affymetrix Cytogenetic 2.7 and Cytoscan HD SNP arrays was performed on 6 NUP98 rearranged leukemias.

Expression data from murine hematopoietic cells expressing BCR-ABL alone, NUP98-HOXA9 alone, BCR-ABL and NUP98-HOXA9, or null for both oncogenes

Project description:Leukemia is a complex malignancy with hundreds of distinct mutations associated with disease development. Studies have shown that oncogenes cooperate to promote leukemia transformation, however, the downstream effectors of this cooperation are largely unknown. Using a genetically defined mouse model of acute leuekmia, we investigated the regulated of genes downstream of the cooperative oncogenic interaction between BCR-ABL and NUP98-HOXA9 and identified a unique gene signature abberrantly expression in leukemia. Total RNA was isolated from hematopoietic cells transduced with BCR-ABL and Nup98-HOXA9 retroviruses and transplanted into recipient mice. Bone marrow cells were purified by GFP (BCR-ABL) and YFP (NUP98-HOXA9) using FACS.

MLL is essential for NUP98-HOXA9-induced leukemia

Project description:Rearrangements involving the NUP98 gene resulting in fusions to several partner genes occur in acute myeloid leukemia and myelodysplastic syndromes. This study demonstrates that the second FG repeat domain of the NUP98 moiety of the NUP98-HOXA9 fusion protein is important for its cell immortalization and leukemogenesis activities. We demonstrate that NUP98-HOXA9 interacts with MLL via this FG repeat domain and that, in the absence of MLL, NUP98-HOXA9-induced cell immortalization and leukemogenesis are severely inhibited. Molecular analyses indicate that MLL is important for the recruitment of NUP98-HOXA9 to the HOXA locus and for NUP98-HOXA9-induced HOXA gene expression. Our data indicate that MLL is crucial for NUP98-HOXA9 leukemia initiation.
