Furthermore, HCC tissues were analyzed via qPCR for the expression of genes associated with M2-like phenotype, including interleukin-10 (IL-10), arginase-1 (Arg1), and YM1, with those associated M1-like phenotype, including iNOS, interleukin-6 (IL-6), and monocyte chemoattractant protein-1 (MCP-1). The gene discussed is IL6; the disease is hepatocellular carcinoma.
