CXCL1 and colitis: CXCL1 expression in the rats from the colitis group fed with feed without beta-glucans (CβG−) was higher compared to the rats from the control group receiving the same feed (HβG−) (Tukey post hoc, p < 0.001), whereas in the colitis rats receiving feed with low- (βGl+) or high-molar-mass oat beta-glucan (βGh+), significantly higher expression of CXCL1 than the CβG− group and a similar level of expression to the control group (HβG−) were observed (Tukey post hoc, p < 0.01).
