DHA attenuates PA-induced inflammatory cytokines overproduction in HepG2 cells. Cells were treated accordingly and then cell-free culture supernatants were assayed for IL-1β (A), IL-18 (B), TNF-α (C) and MCP-1 (D) by commercial ELISA kits. The data represent a mean of 4 experiments. *P < 0.05, **P < 0.01 compared with untreated cells; #P < 0.01 versus 0.4 mM PA-treated cells.
