title: Location and methylation pattern of a nuclear matrix associated region in the human pro alpha 2(I) collagen gene.
abstract: Using both a 25 mM Lithium di-iodosalicylic acid (LIS) and a 2M NaCl extraction procedure to extract nuclear matrices from white cells we have identified a 0.9 kb nuclear matrix associated region (MAR) in the human pro alpha 2(I) collagen gene. The MAR is located towards the 3' coding end of the gene, it is completely associated with the matrix in transcriptionally inactive white cells but is incompletely associated with the matrix in transcriptionally active fibroblasts. Furthermore the methylation state of the fibroblast gene in the region coinciding with the MAR showed unique differences when compared to adjacent sites in the fibroblast gene and corresponding sites of the white cell gene.
