ABSTRACT
<p><b>OBJECTIVE</b>To investigate the expressions of the active form of glycogen synthase kinase-3(GSK-3)-pGSK-3α/β (Tyr279/216) and its downstream moleculor X-linked inhibitor of apoptosis protein (XIAP) in cholangiocarcinoma and to analyze their correlation with clinicopathological and survival significance.</p><p><b>METHODS</b>Immunohistoehemistry was used to detect the expressions of the active form of GSK-3- pGSK-3α/β (Tyr279/216) and its downstream moleculor XIAP proteins in 50 cholangiocarcinoma tissues and 20 normal bile duct tissues.</p><p><b>RESULTS</b>The positive rates of pGSK-3α/β (Tyr279/216) and XIAP were 62.0% and 68.0% in cholangiocarcinoma, and 10.0% and 25.0% in normal bile duct tissues, respectively. The intensity of pGSK-3α/β (Tyr279/216) and XIAP expressions in cholangiocarcinoma were significantly higher than that in the normal bile duct tissues (P < 0.001), and there was a significant correlation between pGSK-3α/β (Tyr279/216) and XIAP expressions (r = 0.544, P < 0.001). The expression of pGSK-3α/β(Tyr279/216) protein in cholangiocarcinoma was associated with TNM stage (P = 0.042), histological grade (P = 0.031), whereas the expression of XIAP protein in cholangiocarcinoma was correlated with CEA level (P = 0.006). Patients with positive expression of pGSK-3α/β (Tyr279/216) and XIAP demonstrate a significantly worse prognosis than that of patients with negative expression of pGSK-3α/β (Tyr279/216) and XIAP for overall survival (P = 0.002, P = 0.018). Multivariate survival analysis revealed that positive pGSK-3α/β (Tyr279/216) expression provided significant independent prognostic value for overall survival (P = 0.002).</p><p><b>CONCLUSIONS</b>The expressions of pGSK-3α/β(Tyr279/216) and XIAP proteins were significantly associated with the development and progression of cholangiocarcinoma. pGSK-3α/β(Tyr279/216) may be an important prognostic factor for survival of patients with cholangiocarcinoma.</p>
