The remission rate of canine lymphoma treated by available combination chemotherapy protocols is usually high (80%-90%). However, most dogs eventually succumb to drug-resistant recurrence, on average, 1 year after diagnosis. Since no more therapeutic option other than chemotherapy, canine lymphoma is simply classified as B cell or T cell type so far. Therefore, offering more therapeutic options for different types of canine lymphoma will be necessary. In this study, flow cytometry (CD3, CD4, CD5, CD8, CD21, CD34, CD45, CD56, and CD79αcy), immunocytochemistry (MUM-1, Bcl-6, Bcl-2, CD10 and KMO) and PCR/RT-PCR (p53, FLT3, NRAS and BRAF) were used to identify the phenotypes of canine lymphoma cell lines, CLBL-1 (B cell type), CLC (non-T non-B cell type) and UL-1 (T cell type). A G485A point mutation causing R162H mutation was found in p53 gene of UL-1 cells. In subsequent viability assay, small molecule inhibitor, kyneurenine 3-monooxygenase (KMO) inhibitor and novel alkylating agents, BO-1055, BO-1922, BO-2094 and BO-1978, significantly reduced proliferation of all cell lines. This revealed their therapeutic potential on canine lymphoma. Future studies will focus on analysis of drugs mechanism.口試委員審定書 I 誌謝 II 中文摘要 II Abstract IV Contents V Chapter 1.
