Immunohistochemieal Study of Expression of nm23 and CD44 Protein in

ABSTRACT

Gene expression of the nm23 and CD44 has been investigated in number of tumors, in cluding colorectal cancer, breast cancer, and hepatocellular carcinoma. This study was conducted to clarify the association between nm23 and CD44 protein expression and metastatic potential in human colorectal cancer. To elucidate the role of the nm23 and CD44 in human colorectal cancer, sections of formalin-fixed, paraffin-embeded tissue from 59 primary colorectal cancer were stained immunohistochemically against nm23 and CD44 proteins. Expression of the nm23 protein is not significantly correlate with Dukes'stage and recurrence. However, the expression of the CD44 protein is significantly higher in Dukes stage C as comparing with stage B.
