Serum cytokine array analysis performed on three tumor-bearing OCM subjects demonstrated increased expression of IL-1β, IL-6, IL-8 and IL-10 at necropsy compared to pre-induction serum levels (Fig. S6A); the pre-induction versus necropsy levels of other cytokines in the array were not significantly different for subjects with tumor. This evidence concerns the gene IL10 and neoplasm.
