| Outline of Final Research Achievements |
The goal of this study is to identify the specific microRNA expression on the canine tumor. To archive this objective goal, small RNA sequence of canine hepatocellular carcinoma, mammary gland tumor, melanoma ware analyzed by RNBA-seq using the next-generation sequencer. In addition, selected microRNA expression ware investigated by real-time PCR in both tumor tissue, blood from canine patients, and cultured cell lines. In melanoma, miR-205 was down and miR-383 was up-regulated. In hepatocellular carcinoma and its cell lines, miR-1 and miR-122 is down regulation and their target mRNA (IGF1R and c-MET) is up-regulated. In mammary gland tumor, grovel miRNA expression was changed depend on malignancy. miR-21 is also up-regulated in blood of the metastatic mammary gland tumor.
