RESEARCH: Tumor viruses and viral biotechnology

We are interested in understanding how tumor viruses, especially Epstein-Barr virus (EBV), causes human carcinomas. Beside nasopharyngeal carcinoma (NPC) that is absolutely associated with EBV infection, 10% of human gastric carcinoma are also found EBV-infected. In comparison to NPC that is mostly restricted in certain geographical areas, the EBV-associated gastric carcinoma (EBVaGC) can be identified throughout the world that may contribute to 100-thousand tumor cases annually. However, the roles of EBV in gastric cancers remain obscure. Our lab has the most state-of-art techniques to manipulate and investigate EBV. We will investigate the fundamental virology of EBV in gastric cells and the roles of EBV transcripts in EBVaGC. We are also investigating the mechanisms viruses in human malignancies that are associating to viral infection. For example: breast cancer, colorectal carcinoma, Cholangiocarcinoma, and autoimmune diseases (Lupus and Multiple Scleroses).

Meanwhile, we are also manipulating the tumor viruses for several applications. We have the unique technique that allows us to modify the giant DNA virus and transform these “terrible viruses” become the useful tools for human. You are welcome to join us and use the viruses to change the world.

我們對於癌症病毒,特別是EBV如何導致人類上皮細胞癌深感興趣。除了鼻咽癌,一種和EBV絕對相關的癌症,目前也發現EBV佔胃癌總體比例也居10%,此類癌症(EBVaGC)每年約造成全球10萬人罹癌,然而此些類癌症之致病機制仍不清楚。我們實驗室具備全世界對此病毒研究之最先進技術,當前我們將主力放在此病毒對胃癌造成之機制。我們也同時研究一些新發現由此病毒導致之癌症種類及疾病,諸如: 乳癌、大腸癌、膽管癌;及自體免疫疾病,諸如多發性硬化症等等。
