| Outline of Final Research Achievements |
In this study, CD44 was found as a liver cancer stem cell marker associated with overall survival in patients with hepatocellular carcinoma (HCC). Furthermore, comparison of the gene and miRNA expression profiles between CD44-positive and CD44-negative HuH7 cells was performed. As a result of miRNA targeted pathway analysis of microarray data, pathway associated with the entire set of miRNA and mRNA including cell adhesion molecule, apoptosis, and ABC transporters in CD44-positive cells were different from those in CD44-negative cells, suggesting that CD44-positive liver cancer stem cell may associated with malignant progression in HCC patients. Additionally, DKK1 and miR-137, which were upregulated in CD44-positive liver cancer stem cell, were associated with poor prognosis of HCC patients and were an independent prognostic factor.
