INTEGRIN ASSOCIATED PROTEINS

这个子项目是众多研究子项目之一

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Integrin receptors bind to extracellular matrix (ECM) ligands and selectively connect to intracellular signaling pathways and the actin cytoskeleton to regulate adhesion-dependent cellular processes. In cancer, the dynamic regulation of adhesion by integrins is critical for cell attachment to ECM, cell proliferation, invasion and cell migration. However, the intracellular downstream effectors of integrins that are important for oral cancer migration, invasion and metastasis are not well understood. Our aim is to compare the composition of integrin associated complexes derived from highly and poorly metastatic oral carcinoma cells. This proteomics study will identify candidate integrin downstream factors that either associate with distinct integrin receptors or specifically associate with integrins in a particular metastatic state. Future studies will delineate whether the identified factors regulate invasion and metastasis, as well as the molecular pathways involved in regulating these metastatic phenotypes.
