Jung et al. demonstrated in their study that methyl parathion and CPF induced the production of inflammatory cytokines, such as tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-1β (IL-1β) in human hepatocellular carcinoma (HepG2) cells [56]. This evidence concerns the gene IL6 and hepatocellular carcinoma.
