  Background: Patients with advanced metastatic cancer often have elevated levels of circulating transforming growth factor beta (TGF-β) that is thought to stimulate receptor mediated signaling through phosphorylated SMAD transcription factors in peripheral blood mononuclear cells. Methods: To identify this TGF-β-dependent gene expression profile in cancer patients, we first evaluated a multi-gene expression profile from ex-vivo treated PBMCs with TGF-β1 stimulation. Change in expression, when challenged with a specific TGF-β receptor type kinase inhibitor was then derived to be ligand and inhibitor specific. Once this profile was established, we examined its role in identifying the activation of a canonical TGF-β1 signaling pathway in patient samples. Results: We discovered a 37 gene sub-set whe..
