Results of a study by Zandi and Karin suggested that curcumin might be efficacious in the treatment of cystic fibrosis because of its anti-inflammatory effect.[121] Curcumin is known to inhibit inflammation by suppressing NF-kB, restricting various activators of NF-kB as well as stemming its expression. The gene discussed is NFKB1; the disease is cystic fibrosis.
