Research Goals

Research is focused on the regulation and molecular mechanisms of extracellular matrix accumulation in mineralized and non-mineralized normal tissues, and on abnormalities that occur in these pathways in oral and systemic pathologies. The roles of extracellular biosynthetic enzymes including lysyl oxidase, and proteolytic processing enzymes such as procollagen N- and C-proteinases are of particular interest. Thus, we analyze the in vitro and in vivo regulation of these enzymes, of other extracellular matrix components, and of selected cytokines under normal and pathologic conditions. These studies have relevance to elucidation of molecular events and mechanisms that occur in normal bone formation, altered bone metabolism in diabetes, drug-induced gingival hyperplasia, and other neoplastic disorders.

microorganisms

Immunohistochemistry of hyperplastic human gingival tissues from a patient undergoing treatment with Dilation (AtoH), and tissue from a patient undergoing therapy with nifedipine (I and J). Sections stained with TGF-b1 antibody are shown in A, B, and I. A and B are photos of the same section, but different magnifications. The section shown in C is stained with nonimmune IgG and is a serial section of that shown in A and B. Sections stained with CTGF antibody are shown in D, E, and J, D and E show different magnifications of the same section. The section shown in F is stained with preimmune IgG and is a serial section of that shown in D and E. The section stained with lysyl oxidase antibody is shown in G, and the serial section (H) is stained with nonimmune IgG. Hong, et al. 79 1655-1666, 1999.
