CRP and colorectal cancer: Colonic expression of PAP/Reg3β is higher during inflammation-induced colorectal cancer and in the course of acute and chronic chemically-induced colitis in mice, whereas no significant changes are observed during the recovery phase.[11]–[13] In human subjects, PAP/Reg3β is over-expressed in the intestinal mucosa of patients with inflammatory bowel disease (IBD).[9], [11], [14] Importantly, clinical and endoscopic disease severity seems to correlate with serum PAP/Reg3β in parallel with C reactive protein (CRP) levels and erythrocyte sedimentation rate.[9]
