Identification of transcriptional network regulated by FGFR1 fusion kinase in stem cell leukemia and lymphoma (SCLL)

Purpose: Oncogenic transformation of hematopoietic stem cells by chimeric fusion kinases causing constitutive activation of FGFR1 leads to a stem cell leukemia/lymphoma (SCLL) syndrome, accompanied by widespread dysregulation of gene activity. The goals of this study are to use NGS-derived transcriptome profiling (RNA-seq) to identify genes regulated by FGFR1 fusion kinase in SCLL. Methods: Three different cell models for SCLL, respectively BBC2 (B cell lymphoblastic leukemia/lymphoma), ZNF112 (B cell lymphoblastic leukemia/lymphoma) and BCRF8C (myloid leukemia) were treated with selective FGFR1 kinase inhibitor,then the total RNA from treatment and viechel control were isolated for RNA-Seq analysis. Results: A global gene experssion change is generated, and provides fundamental information for demostration of molecular mechanisms in FGFR1 driven leukemogenesis. comparasion of the transcriptomes of SCLL lines with and without the inhibition of FGFR1
