In DSS colitis, restitution and healed lesions in Muc2+/+ but not Muc2-/- littermates, were accompanied by a rapid increase in Fcgbp mRNA and delayed protein expression at 12- and 15-days post DSS, implicating a potential novel endogenous protective role for FCGBP in wound healing to maintain epithelial barrier function. The gene discussed is MUC2; the disease is colitis.
