The overall goal of the Molecular Biology Section is to discover novel molecular mechanisms that underlie the development of hard tissues and ectodermal organs, by identifying novel functions of previously unstudied genes and defining the roles of the extracellular matrix (ECM). They have focused on the novel roles of protein factors and ECM components in proliferation, differentiation, and cell adhesion during development of teeth, cartilage, and other tissues. These studies are aimed towards developing reagents useful for diagnostic and therapeutic applications. Most recently, we identified several novel proteins from a tooth germ cDNA library, including the transcription factor epiprofin, the odontoblast adhesion protein fibulin7 (TM14), and the gap junction protein pannexin 3. These proteins are expressed in teeth as well as in tissues such as cartilage, bone, and skin. We expect that identification of common and distinct molecular mechanisms for the function of these proteins in specific tissue types will uncover key concepts that underlie both normal development and disease.
Dr. Yamada received his Ph.D. from Osaka University Faculty of Science. After receiving his Ph.D., he began his postdoctoral training at the University of Pittsburgh, where he investigated gene regulation of bacteriophages and plasmids. In 1978, he moved to the National Cancer Institute at NIH to study gene evolution and regulation of collagen genes. In 1983, he joined the NIDCR, where he has been studying the functions of basement membrane components, cartilage matrices, and other extracellular matrices during development and diseases.
