NUDCD1 and colorectal cancer: Moreover, it was found that the protein expression of NudCD1 was significantly higher in poorly differentiated colorectal cancer as compared with moderately differentiated and well differentiated colorectal cancer (Fig. 2B: well differentiated, with high expression of 58.00% and staining score of 8.2 ± 0.8, χ2 = 56.536, P < 0.01; Fig. 2C: moderately differentiated, with high expression of 62.30% and staining score of 9.3 ± 0.7, χ2 = 59.752, P < 0.01; Fig. 2D: poorly differentiated, with high expression of 68.40% and staining score of 9.9 ± 0.6, χ2 = 66.658, P < 0.01).
