DESCRIPTION OF LAB RESEARCH WORK
My laboratory is interested in characterizing the role of N-WASP (Neural Wiskott Aldrich Syndrome Protein) in cellular processes such as cell proliferation and migration, processes which play a critical role in Metastasis. N-WASP is an ubiquitously expressed adaptor protein which regulates actin cytoskeleton by activating of the Arp2/3 complex. Expression of N-WASP has been found to be reduced in a number of cancers and increased in other cancers. Our working hypothesis is that N-WASP is a tumor suppressor in early stage cancer and a tumor promoter in late stage cancer. In order to characterize the in-vivo role of N-WASP in various cellular processes we have generate N-WASPfloxed mice. Using this mice and appropriate Cre expressing mice we have characterized the role of N-WASP in fibroblast and Keratinocytes. We are presently characterizing the role of N-WASP in tumorigenesis, epithelial-to-mesenchymal transition, metastasis and wound healing.
