| Outline of Final Research Achievements |
The present study identified novel cancer markers for opisthorchiasis-associated cholangiocarcinoma (CCA). After further study on the candidates listed up based on our previous cDNA microarray analysis, we focused on the two markers, MFGE8 and S100P. The early elevation of expression in Opisthorchis viverrini infection-induced cholangiocarcinoma (CCA) animal model, intensive expression in the precancerous lesion of hyperplasia and dysplasia in bile ducts and tumor cell, and high levels in serum and bile fluid indicated that both can be novel markers for CCA diagnosis. The high expression could be an independent prognostic factor. The shRNA-mediated knockdown of S100P expression inhibited the proliferation of CCA, arrested cell cycle, promoted apoptosis and increased the sensitivity to chemotherapeutic agents. This study indicates that MFGE8 and S100P are promising novel biomarker for diagnosis, prognosis and therapy of CCA.
