title: DNAase-I-hypersensitive sites in the mouse albumin gene.
abstract: We have analyzed the DNAase I sensitivity of the mouse alpha-fetoprotein and albumin structural genes from fetal liver, adult liver and kidney. The albumin gene shows distinct hypersensitive sites in adult liver in addition to an overall DNAase I sensitivity, but is only slightly nuclease-sensitive in fetal liver. The alpha-fetoprotein gene does not show hypersensitive sites but displays an overall DNAase I sensitivity in fetal liver; however, it is nuclease-insensitive in adult liver. Both genes are insensitive to DNAase I in kidney. The presence of DNAase-I-hypersensitive sites in the albumin structural gene correlates with extensive demethylation of the gene in adult liver.
