GLT down-regulates expression of COX-2 in colon tissue.

(A) Immunohistochemistry and (B) quantification of COX-2 positive cells were performed as described in Materials and Methods. Box plots represent 5th/10th percentiles, horizontal bars represent median values, and whiskers indicate minimum to maximum values. Significant differences (*p<0.05) were observed among PhIP/DSS vs. control, PhIP/DSS vs PhIP/DSS+GLT 100, and PhIP/DSS vs. PhIP/DSS+GLT 100.
