MNase and HpaII sensitivity assays in MCF7 breast cancer cells
DNA are packaged into nucleosomes and chromatin. We performed incomplete MNase digestion of chromatin to identify "nucleosome-free" regions that may indicate active promoters and regulatory regions. Additionally, HpaII digestion was performed which cleaves CCGG sites when the internal C remains unmodified. The hypomethylation state and nuclease sensitivity of the chromatin are indicators of transcription regulatory regions.
