Abstract:
Objective To investigate the role of Ki-67,c-myc,p53 in human in esophageal cancer.Methods 25 specimens of human esophageal cancer as observe group and 25 adjacent normal specimens as control group were selected.Expressions of Ki-67,c-myc,p53 protein were detected by immunohistochemical staining.Results Protein expressions levels of Ki-67,c-myc and p53 in human esophageal cancer were significantly higher than those in control group 5.0,2.0,3.0 vs 1.0,0.5,0.3,respectively (all P ＜ 0.05).The expression level of Ki-67 protein in high differentiation group were significantly lower than that of moderate and low differentiation group (3.0 vs 6.0,P ＜ 0.05).In human esophageal cancer specimens,the expression level of Ki-67 protein was positively correlated with that of c-myc (P ＜ 0.05).Conclusion The expressions of Ki-67,c-myc and p53 are higher in esophageal cancer,which are increased with the higher differentiation.Ki-67,c-myc and p53 proteins may be taken as potential markers in human esophageal cancer.
