Expression of Ezrin and AnnexinⅡin gallbladder carcinoma / 实用医学杂志

ABSTRACT

Objective To investigate the expression levels of Ezrin and AnnexinⅡ in gallbladder carci-noma and their association with clinicopathologic parameters and metastasis potential. Methods The tissue mi-croarray consisted of 59 gallbladder carcinoma tissues and 6 normal gallbladder tissues were examined for the ex-pression of Ezrin and AnnexinⅡusing immunohistochemistry technique. The expression of Ezrin and AnnexinⅡin 20 cases of fresh gallbladder carcinoma and 6 cases of normal gallbladder were measured with western blot. Results The expression of Ezrin and AnnexinⅡ were higher in the gallbladder cancer than those in the normal gallbladder tissue. The positive rate of Ezrin and AnnexinⅡ were 47.5% and 50.8% respectively. The expression of Ezrin was significantly correlated with live metastasis , lymph node metastasis and Nevin stages. The expression of AnnexinⅡwas significantly correlated with live metastasis , differentiation levels and Nevin stages. The expres-sion of Ezrin was correlated with AnnexinⅡ. Results of western blot suggested that Ezrin and Annexin II were highly expressed in gallbladder carcinoma tissues. The high expression of Ezrin and Annexin is closely related with liver invasion. Conclusion Measurement of the expression of Annexin and Ezrin II have important clinical significances to evaluate the malignant biological behavior of gallbladder carcinoma.
