ABSTRACT: The NFM-NM-:B transcription factor is constitutively active in a number of hematologic and solid tumors, and many signaling pathways implicated in cancer are likely connected to NFM-NM-:B activation. A critical mediator of NFM-NM-:B activity is TGFM-NM-2-activated kinase 1 (TAK1). Here, we identify TAK1 as a novel interacting protein and direct target of fibroblast growth factor receptor 3 (FGFR3) tyrosine kinase activity. We further demonstrate that activating mutations in FGFR3 associated with both multiple myeloma and bladder cancer can modulate expression of genes which regulate NFM-NM-:B signaling, and promote both NFM-NM-:B transcriptional activity and cell adhesion in a manner dependent on TAK1 expression in both cancer cell types. Our findings suggest TAK1 as a potential therapeutic target for FGFR3-associated cancers, and other malignancies in which TAK1 contributes to constitutive NFM-NM-:B activation. A total of 12 samples of MGHU3 (Y375C) mutant FGFR3 bladder cancer cells (a kind gift from Dr. Margaret Knowles (University of Leeds, Leeds, UK)) were used for array-based gene expression analysis. 3 replicates of each condition: Control siRNA, Control siRNA + PD173074, TAK1 siRNA, and TAK1 siRNA + PD173074.
