Effect of LPS (10 µg/ml) in the presence or absence of AtRA (10-7 M) on NO2 (a) and TNF-α (b) mRNA expression in colonic mucosa of patients with active UC and CAC. Values represent mean ± standard deviation. Significance compared with control: , (UC: ulcerative colitis; CAC: colitis associated cancer).
