Pyrrolidine dithiocarbamate inhibits cytokine-induced VCAM-1 gene expression in rat cardiac myocytes

Abstract

We investigated whether interleukin-1alpha (IL-1) would induce gene expression of vascular cell adhesion molecule-1 (VCAM-1) in cardiac myocytes and, if so, whether nuclear factor kappaB (NF-kappaB) was involved. We evaluated the VCAM-1 gene expression in cultured neonatal rat cardiac myocytes by the reverse transcription-polymerase chain reaction. IL-1 alone or together with interferon-gamma (IFN) induced VCAM-1 gene expression in the cells. Induction of VCAM-1 gene expression in response to IL-1 and IFN was antagonized in a concentration-dependent manner by pyrrolidine dithiocarbamate, an inhibitor of NF-kappa b activation (25-100 microM). Tosyl-lysine-chloromethyl ketone, another inhibitor of NF-kappa b activation, also inhibited the expression of the VCAM-1 gene in response to IL-1 and IFN. Thus, VCAM-1 gene expression appeared to be mediated by NF-kappa b in cardiac myocytes, and this cardiac myocyte VCAM-1 may be involved in cardiac inflammatory disorders. Disruption of expression of VCAM-1 by inhibition of NF-kappa b activation may indicate a target for pharmacologic intervention intended to limit cardiac inflammation.

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function.
