Outline of Final Research Achievements

The aim of this study is to develop a new therapeutic strategy targeting the specific cell population and its molecular mechanism.
Microarray analysis revealed the lower miR-5100 expression in the highly metastatic pancreatic cancer cell, and we found the fact that the expression of PODXL, a target gene of miR-5100, correlates with the patients’ survival and the frequency of liver metastasis. PODXL knock down in the pancreatic cancer cell decreased its aggressive phenotype, suggesting that PODXL is a potential therapeutic target to inhibit liver metastasis.
Further, observation of the liver and lung metastasis mouse model revealed the fact that liver metastases contains significantly more α-SMA positive stromal cells than lung metastases.
