ABSTRACT
Objective To investigate the expressions of claudin-5 and claudin-10 in colorectal carcinoma(CRC) and its significance.Methods Pathological verified 50 colorectal tissue (CRT),25 colorectal adenoma (CRA),25 non lymph node metastasis CRC (non-LNM CRC) and 25 lymph node metastasis CRC (LNM CRC) were detected for the expression of claudin-5 and claudin-10 by immunohistochemical SP(streptavidin perdcidase) method.Results The positive expression rate of Claudin-5 was 82%,76%,68% in CRT,CRA,CRC,respectively.The positive expression rate of claudin-5 in different groups was not significantly different(X~2 =2.638,P>0.05).claudin-5 expression was correlated with LNM (P<0.05),but was not correlated with gender,age,tumor,location,differentiation,tumor diameter and serous membrane invasion(P>0.05).The positive expression rate of claudin-10 was 54%,56%,72% in CRT,CRA,CRC,respectively.The positive expression rate of claudin-10 in different groups was not significantly different(X~2 = 3.839,P>0.05).claudin-10 expression was correlated with tumor diameter,serous membrane invasion and LNM (P<0.05),but was not correlated with gender,age,location and differentiation (P>0.05).There was no significant correlation between claudin-5 expression and claudin-10 expression in CRC (r = 0.050,P = 0.732).Conclusions claudin-5 and clandin-10 are expressed in CRT,CRA,and CRC.They are not involved in CRC occurrence,claudin-5 and clandin-10 abnormally expressions are significantly associated with the incidence of LNM.Meanwhile,claudin-10 expression is correlated with tumor diameter and serous membrane invasion.There was no significant correlation between claudin-5 expression and claudin-10 expression in CRC.
