After 3 and 7 days of TNBS administration, the expression of CXCL1 decreased in the rats with induced colitis fed with feed without beta-glucans (CβG−) compared to the control group (HβG−), while in the CβGl+ and CβGh+ groups, the expression level of this chemokine was at a similar level as in the control group (HβG−). The gene discussed is CXCL1; the disease is colitis.
