Higher concentrations of several cytokines were found in the MCL clinical cases compared to CL cases (Fig 1): the growth factors VEGF (P = 0.008) and HGF (P = 0.018); the chemokines eotaxin (P = 0.005), MIP-1α (P = 0.025), MIG (P<0.001) and IP-10 (P = 0.006); the pro-inflammatory cytokine IL-6 (P = 0.003) and the TH2 cytokine IL-13 (P = 0.042). The gene discussed is VEGFA; the disease is mantle cell lymphoma.
