Abstract
Abstract
Genomic variations such point mutations and gene fusions are directly or indirectly associated with human diseases. They are recognized as diagnostic, prognostic markers and as therapeutic targets. However, predicting the functional impact of these genetic alterations beyond affected genes and their products is challenging because diseased phenotypes likely result in complex molecular interaction networks. Using as models three different chromosomal translocations ETV6-RUNX1 (TEL-AML1), BCR-ABL1, and E2A-PBX1 (TCF3-PBX1) frequently found in B-cell acute lymphoblastic leukemia (B-ALL), we develop an approach to extract from gene expression changes, perturbed molecular interactions. We show that the Myc and JunD transcriptional circuits are specifically deregulated following TEL-AML1 and TCF3-PBX1 gene fusions, respectively. We also identified the bulk mRNA NXF1-dependent machinery as a direct target for the TCF3-PBX1 fusion protein. Through a novel approach combining gene expression and interactome data analysis, we provide new insight into TCF3-PBX1 and TEL-AML1 acute lymphoblastic leukemia.
