Abstract:
Objective To investigate the expression of cytokine induced apoptosis inhibitor 1 (CIAPIN1) protein in colon cancer tissues and its relationship with the pathological features of tumor.Methods A total of 80 cases of colon cancer tissues and 40 cases of paracancer tissues were collected from our hospital after surgery from January 2014 to January 2017.Immunohistochemical staining and Western blotting were used to detect the expressions of CIAPIN1 protein in the two types of specimens.The relationships between CIAPIN1 protein and the occurrence and development of colon cancer were analyzed.Results The positive rate of CIAPIN1 protein expression in colon cancer tissues was significantly lower than that in paracancer tissues (30.0％ vs.85.0％,x2 =32.303,P ＜0.001).The relative expression level of CIAPIN1 protein in colon cancer tissues was significantly lower than that in paracancer tissues (0.507 ±0.183 vs.1.874 ±0.361,t =22.513,P ＜0.001).The positive expression rate of CIAPIN1 in colon cancer tissues was not correlated with the age (x2 =0.086,P =0.769),sex (x2 =0.779,P =0.377),tumor invasion depth (x2 =0.879,P =0.348),tumor location (x2 =0.725,P =0.395),tumor size (x2 =2.241,P =0.134),tumor differentiation status(x2 =1.372,P =0.241),and the pathological type (P =0.715),but was significantly correlated with lymph node metastasis (x2 =10.813,P =0.001) and clinical stage (x2 =5.610,P =0.018).Conclusion The expression of CIAPIN1 protein in colon cancer tissues reduces significantly,and is correlated with clinical stage and lymph node metastasis.
