Abstract

This invention relates to agents that regulate the proliferation of cells such as smooth muscle cells. Proliferation of smooth muscle cells may be increased or decreased by affecting the activity or concentration of a transcription factor. The factor comprises two domains of about 50 kD and about 70 kD which together have an approximate molecular weight of 120 kD and specifically binds to the nucleic acid sequence 5'-GGGTTTTCCCC-3' (SEQ ID NO 2). This factor represents a novel member of the family of rel-related factors. This invention also relates to methods for the treatment and prevention of diseases and disorders associated with proliferation of smooth muscle cells such as arteriosclerosis, fibrosis and wound healing, which involve regulation of the smooth muscle cell transcription factor. The invention further relates to purified transcription factor, to pharmaceutical compositions containing transcription factor or inhibitors or inducers of the transcription factor, to nucleic acid sequences which code for the subunits of the factor, and to recombinant cells transformed with these sequences. Novel rel-related factors can also be used to regulate gene expression and the proliferation of organisms such as cells and viruses which may contain rel-related binding elements.
