DCLK1 and neoplasm: Notwithstanding the observed reduction of DCAMKL-1 positive cells in tumours compared with the normal mucosa (Figure 8), the percentage of cells co-expressing DCAMKL-1 and nuclear β-catenin was higher in tumours than in the normal mucosa (LI: 0.39±0.13 in tumours and 0.04±0.02 in normal mucosa; P<0.01 with paired t-test).
