The Role of Nuclear Matrix Proteins Binding to Matrix Attachment Regions (MARs) in Prostate Cancer Cell Differentiation

Abstract excerpt

In tumor progression definite alterations in nuclear matrix (NM) protein composition as well as in chromatin structure occur. The NM interacts with chromatin via specialized DNA sequences called matrix attachment regions (MARs). In the present study, using a proteomic approach along with a two-dimensional Southwestern assay and confocal laser microscopy, we show that the differentiation of stabilized human...
