n‐3 polyunsaturated fatty acids attenuate induced colitis by reducing inducible nitric oxide synthase (iNOS), cyclooxygenase‐2 (COX‐2), IL‐6, and LTB4 as well as regulating tight junction proteins (occludin, claudin‐1) and colonic mRNA levels of trefoil factor 3 (TFF3) and mucin 2 (MUC2) (Charpentier et al., 2018). The gene discussed is IL6; the disease is colitis.
