We sincerely invite Ph.D. program students who are interested in the studies of (1) host-virus (EBV and influenza virus) interaction and (2) DcR3-induced epithelial-mesenchymal transition (EMT) to join the lab.

Our lab currently has a technician position open for people who are interested in influenza virus research. The position is effective immediately. (posted Oct. 2009)

Fourth-year Ph.D. student, CH Ho, has been graduated this summer and becomes Dr. CH Ho after publishing his second paper in four years!

EBV genome is packed as a chromosome-like episome at latency. Previous studies indicated that lytic replication initiates with the theta (θ)-form replication and switches to roll-circle mode after several rounds of viral DNA replication. However, the cellular and viral activities involved in the transition from histone-associated genome to θ-replication remain unclear. The first project we are interested is to identify the chromatin dynamics on EBV lytic replication origin (OriLyt). We look for the changes of histone modification (acetylation and methylation) and the factors, both cellular and viral, that are responsible for the changes.

The second project we focus on is to study how decoy receptor 3 (DcR3) is regulated by exogenous factors, such as viral infection or pro-inflammatory cytokines. Both EBV and DcR3 are implicated in the development of human malignancies. DcR3 overexpression is previously demonstrated in EBV-associated lymphomas, suggesting EBV may use DcR3 as a tool to escape host immune surveillance and help EBV-infected cells gain survival advantage. We successively identified that expression of EBV lytic transactivator Rta and latent membrane protein 1 (LMP1) leads to DcR3 up-regulation. We also identified that two pro-inflammatory cytokines, TNFα and IL-6, govern DcR3 expression. The detailed mechanism of pro-inflammatory cytokines regulating DcR3 expression is under investigation.

The third project we are working on is to study the association between DcR3 and chronic kidney disease (CKD). In collaboration with Dr. Der-Cherng Tarng (Department and Institute of Physiology, NYMU), we are work toward to demonstrate the function of DcR3 in CKD. We focus on the role of DcR3 in tubular epithelial-mesenchymal transition (TEMT), which has an important implication in CKD progression.
