Objective To investigate MUC1 over-expression on chemotherapy of 5-fluorouracil and cisplatin for esophageal cancer cells. Methods MUC1 over-expression and stable silencing of MUC1 expression esophageal cancer cell lines were constructed. Xenograft model of esophageal cancer was established in nude mice. Cisplatin (8 mg/kg, day 1 and day 7)and 5-fluorouracil (20 mg/kg, day 1 to 6)were injected intraperitoneally. Tumor volume and body weight of nude mice were measured. Tumor growth curve and body weight curve were drawn, and tumor inhibitory rate was calculated. Results Both cisplatin and 5-fluorouracil suppressed tumor growth of MUC1 over-expression esophageal cancer nude mice. Body weight and tumor volume of nude mice of cisplatin and 5-fluorouracil groups were significantly smaller than those of the control group (P < 0.05), and the inhibitory effects of cisplatin were significantly greater than those of 5-fluorouracil (P < 0.05). There was no significant inhibitory effect in stable silencing of MUC1 expression esophageal cancer nude mice. Conclusion Both cisplatin and paclitaxel can suppress the growth of MUC1 over-expression esophageal cancer, and cisplatin has greater inhibitory effects than 5-fluorouracil in tumor volume and body weight of nude mice.
