Abstract:
Objective To investigate the expression of Notch1 protein and its clinicopathologieal characteristics in colorectal carcinomas. Methods The expression and location of Notch1 protein were determined using immunohistochemical S-P method in 30 colorectal carcinomas and 18 normal colorectal tissues. Results The average positive rate of Notch1 protein was 45.5 ± 0. 7% in colorectal carcinomas and 6. 8 ± 0. 9% in normal colorectal tissues. There was significant difference between colorectal carcinomas and normal colorectal tissues (P ＜ 0. 05). The expression of Notchl protein in different age, sex, tumor site, nodal involvement and Dukes stage had no significant difference. The expression of Notch1 protein in different histology grade had significantly statistical difference. Conclusion Notch1 expression was associated with the development of colorectal carcinoma. Notch1 was the potential oncagenic gene. Nothe1 would become the new target of the colorectal tumor therapy in the future.
