Expression of NudCD1 protein in normal tissue and colorectal tumor tissue. NudCD1 was mainly expressed in the cytoplasm of intestinal mucosal gland, with brown or tan particles of different area and brightness. Compared with normal intestinal tissues (A high expression of 8.00%, staining score was 5.2 ± 0.4), protein expression of NudCD1 was significantly higher in colorectal cancer tissue with different differentiation (B Well-differentiated, high expression of 58.00%, staining score was 8.2 ± 0.8, χ2 = 56.536, P < 0.01; C. Moderately differentiated, high expression of 62.30%, staining score was 9.7 ± 0.7, χ2 = 59.752, P < 0.01; D. Poorly differentiated, high expression of 68.40%, staining score was 9.9 ± 0.6, χ2 = 66.658, P < 0.01). Images were taken at magnification of 200 ×
