Study on the clinical significance of Argonaute2 expression in colonic carcinoma by tissue microarray

Int J Clin Exp Pathol. 2013;6(3):476-84. Epub 2013 Feb 15.

Abstract

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.

Keywords: Argonaute2; Tissue mircroarray; colonic carcinoma; immunohistochemstry.
