Immunohistochemical expression of SP-NK-1R-EGFR pathway and VDR in colonic inflammation and neoplasia

Figure 2 Expression of neurokinin-1 receptor in colonic tissue. A: Neurokinin-1 receptor (NK-1R) expression in tissue from normal, inflammatory bowel disease (IBD), sporadic dysplasia, sporadic colorectal cancer, and colitis-associated colorectal cancer (CAC) patients (n = 5 patients per group); B: Expression of NK-1R in different diagnostic areas found within tissue from CAC patients. Each patient is identified by a unique symbol (Table 2). IHC: Immunohistochemistry.
