Table 1 specifies those genes (with cell-surface gene products) up-regulated in the CINI and CINIII stages of dysplasia and Table 2 lists genes up-regulated in normal tissue. Short descriptions of these protein biomarkers are given in the appendix and annotations of protein structural information, if available, are included. Given that CINII is difficult to determine clinically, it was not included in these comparisons. Contrast agent visualization of the epidermal growth factor receptor (EGFR) using an anti-EGFR monoclonal antibody has already been successful (Rahman et al. 2005). This evidence concerns the gene EGFR and dysplasia.
