Genome-wide profiling of miRNA associated with BCR-FGFR1 fusion kinase driven stem cell leukemia and lymphoma I

ABSTRACT: The BBC1 and BBC2 cell lines were isolated from pre-B-cell lymphoma models of a murine BCR-FGFR1 driven SCLL. miRNA profiles for BBC2 cells, were established using miRNA arrays. First, BBC2 cells were compared with FACS sorted, normal, murine splenic CD19+ B cells isolated from BALB/c mice, where upregulated and downregulated miRNAs in BBC2 cells were identified. We next investigated which of these miRNAs were affected by loss of FGFR1 function. Previously we showed that the FGFR inhibitor BGJ398 suppresses suppressed phosphoactivation of chimeric FGFR1 kinases. When BBC2 cells were treated with 50nM BGJ398 for 24 hours, up- and down-regulated miRNAs by FGFR1 signaling were identified. By comparasion of the two subsets of differentially expressed miRNAs, we were able to define core candidate miRNAs which appear to be regulated by BCR-FGFR1 in SCLL.

ZMYM2/FGFR1, BCR/FGFR1 or BCR/ABL1 in human cord blood CD34+ cells reveals similar but distinct gene expression profiles

Project description:The 8p11 myeloproliferative syndrome (EMS), also referred to as the stem cell leukemia/lymphoma syndrome, is a chronic myeloproliferative disorder that rapidly progresses into an acute leukemia. Molecularly, EMS is characterized by fusion of various partner genes to the FGFR1 gene, resulting in constitutive activation of the tyrosine kinase activity within FGFR1. The two most common fusion genes in human EMS are ZMYM2/FGFR1 (previously known as ZNF198/FGFR1) and BCR/FGFR1. To study the transcriptional programs becoming deregulated by the FGFR1 fusion genes, global gene expression analysis on human CD34+ cord blood cells expressing either of the fusion oncogenes ZMYM2/FGFR1 and BCR/FGFR1 was performed. As a reference gene we also included the more studied BCR/ABL1 fusion oncogene associated with chronic myeloid leukemia. We found that the 3 different fusion oncogenes had in common the upregulation of several genes involved in the JAK/STAT signalling pathway and also other sets of genes. However, the gene expression profiles were not identical, suggesting that both the tyrosine kinase containing gene and the partner gene would affect the transcription of downstream target genes. Bicistronic retroviral murine stem cell virus (MSCV) vectors expressing ZMYM2/FGFR1, BCR/FGFR1or P210 BCR/ABL1 and GFP were used. The MIG control vector expressed GFP only. Two days post transfection of human CD34+ umbilical cord blood cells, GFP-sorted cells were collected in three biological replicates and RNA was isolated immediately. In total, 12 samples were hybridized and scanned.

FGFR1 Signature

Project description:The gene encoding fibroblast growth factor receptor 1 (FGFR1) amplification is associated with poor prognosis in estrogen receptor positive (ER+) breast cancer, and thus represents a potential therapeutic target. Fluorescent in situ hybridization (FISH) has been used as the gold standard methodology for detection of FGFR1 amplification, but it is a relatively long labor-intensive procedure and not efficient to process a large number of patient samples, especially formalin fixed paraffin embedded (FFPE) samples. This study sought to identify genes discriminative at the mRNA level for FGFR1 amplification and to construct a multi-gene test to facilitate efficient screening for FGFR1 amplified ER+ breast tumors.

FGFR1 associates with gene promoters and regulates gene transcription: Implications for endocrine resistance in ER+/FGFR1-amplified breast cancer (RNA-seq)

Project description:Using ChIP-Seq analysis of ER+/FGFR1-amplified breast cancer cells and PDXs, we found FGFR1 occupancy at transcription start sites with high overlap with histone modifications associated with active gene transcription. Mass spectrometry analysis of the nuclear and chromatin-bound FGFR1 interactome identified RNA-Polymerase II (Pol II) and FOXA1, with FOXA1 silencing impairing FGFR1 recruitment to chromatin. Transduction of FGFR1(SP-)(NLS) into MCF7 cells resulted in overexpression of nuclear FGFR1 and resistance to antiestrogens. Finally, an expression signature associated with nuclear FGFR1 correlated with endocrine resistance in patients treated with antiestrogens
