Moreover, dasatinib was active in a NUP214-ABL1-positive leukemia xenograft murine model and in marrow lymphoblasts from a patient with NUP214-ABL1-positive T-ALL.
The mechanism by which the fusion protein DEK-NUP214 contributes to leukemia development has not been identified, and disruptions of normal cellular functions by DEK-NUP214 have previously not been described.
RNA-sequencing proved to be a valuable tool for the detection of a fusion of genes DEK and NUP214 in a leukemia that showed cryptic cytogenetic rearrangement of chromosome band 9q34.
They have been shown to induce leukemia in mice and to enhance proliferation and disrupt differentiation in primary human hematopoietic precursors.NUP214 has only a few fusion partners.
MLL-r leukemia cells that were resistant to the compound were characterised by significantly higher baseline gene expression levels of MEIS1 and BCL2 in comparison to CCI-007 sensitive MLL-r leukemia cells.In conclusion, we have identified CCI-007 as a novel small molecule that displays rapid toxicity towards a subset of MLL-r, CALM-AF10 and SET-NUP214leukemia cell lines.
The scope of this review is to summarize the general features of NUP214-related leukemia and discuss how distinct chromosomal translocation partners can influence the cellular effects of NUP214 fusion proteins in leukemia.
Of 141 human leukemia/lymphoma cell lines tested, only the T-ALL cell line LOUCY and the AML cell line MEGAL expressed the SET(TAF-Ibeta)-NUP214 fusion gene transcript.
