By ELISA or flow cytometric bead-based immunoassays, we quantified the media concentrations of three permeability-inducing and/or pro-inflammatory cytokines, whose elevated levels in cancer patients often correlate with disease progression and poor prognosis: VEGF, IL-8, and IL-6 (Ferrara, 2005; Kut et al, 2007; Lippitz, 2013). This evidence concerns the gene IL6 and cancer.
