A previous study showed that linoleic acid isolated from A. brasiliensis KA21 inhibits NO production and suppresses the expression of genes encoding pro-inflammatory cytokines, including Tnfa, interleukin 6 (Il6), interleukin 1-beta (Il1b), and nitric oxide synthase 2 (Nos2) in murine leukemia macrophage cell (RAW 264.7 cells) [5]. The gene discussed is TNF; the disease is leukemia.
