Abstract
The nuclear matrix is the RNA-protein skeleton within the nucleus that contributes to the structural and functional organization of DNA. Differences in the nuclear matrix protein composition between cancer and normal cells have been reported in various cell lines and tissues, suggesting altered gene expression. This study examined the nuclear matrix protein composition of various human lung cell lines. Using high resolution two-dimensional electrophoresis, at least ten common proteins, as well as specific differences, were identified in each category of lung cell lines. These protein differences may be responsible, at least in part, for the different phenotypes of human lung cancer.
