Jung Weon Lee, Professor of Seoul National University, Seoul, Korea. He got a Ph.D. degree in Pharmacology, from Department of Pharmacology, University of North Carolina at Chapel Hill, NC, USA. His is currently a professor at Department of Pharmacy, Seoul National University, Seoul, Korea (Republic of). His research interests in signal transduction of membrane proteins including integrin, tetraspanin, growth factor receptor, and others, which are involved in cell adhesion, morphology, migration, and invasion through activations of diverse intracellular signaling connections. More specifically, he has published reports on fibrotic and tumorigenic roles of a tetraspanin TM4SF5 that can collaborate with integrins and growth factor receptors for diverse cellular functions for tumorigenesis and metastasis. For the researches, he uses in vitro cell cultures in 2D or 3D ECM-surrounded system, animal system, and clinical tissues. The key words for his researches can include cancer, signal transduction, cell adhesion, actin organization, migration, invasion, 3D environment, metastasis, and epithelial-mesenchymal transition.
