Study On The Clinical Significance Of Argonaute2 Expression In Colonic Carcinoma By Tissue Microarray

Background: To study the expression levels and clinical significance of Argonaute2 (EIF2C2) on colonic carcinomas and normal tissues. Methods: Colon tissue samples from 90 cases of colonic carcinomas and 90 normal subjects were accumulated and made into a tissue microarray containing 360 dots. Expression of Argonaute2 (EIF2C2) was detected by immunohistochemical staining of the tissue microarray. Results: There was significant difference in the expression levels of Argonaute2 (EIF2C2) between colonic carcinomas and normal tissues (P<0.01). However, the expression of Argonaute2 (EIF2C2) was not related to sex, age, position, differentiation, lymphatic metastasis and clinical stage of the tumor (P>0.05). Conclusion: Abnormal expression of Argonaute2 (EIF2C2) may be correlated with colon tumorigenesis.
