ABSTRACT
Objective To investigate the expression of Vacuolar-H +-ATPase (V-ATPase) and P-glyeoprotein (P-gp) protein in colon carcinoma tissues,the correlation between the expression of V-ATPase and P-gp and their clinicopathological significance.Methods In samples from 80 cases of colon cancer,20 cases of colon adenoma and 10 cases of normal colonic mucosa tissues,the expression of V-ATPase and P-gp protein were detected by immunohistochemical method,their relationship was analyzed,the clinicopathological features and prognosis were evaluated.Results In colon cancer,V-ATPase and P-gp protein expression was 72% and 80%,higher than that in colon adenomas (40%,35%),and in normal colon mucosa (20%,20%),the difference was statistically significant (P < 0.05).There was a positive correlation between the expression of V-ATPase and that of P-gp (r =0.567,P <0.01).V-ATPase and P-gp protein expression in colon cancer was associated with TNM stage,lymph node metastasis and tumor differentiation (P < 0.05).Patients with high V-ATPase expression had lower 5-year survival rate than those with low V-ATPase expression (P =0.023),and 5-year recurrence rate was higher than those with low expression (P =0.024).Conclusions The expression of V-ATPase is up-regulated in colon cancer,there is a positive correlation with colon cancer progress and metastasis,and high V-ATPase protein expression predicts poor prognosis.
