SAMMY-seq, H3K9me3 and H3K27me3 ChIP-seq and RNA-seq of control and progeria fibroblasts
We present a new high-throughput sequencing-based technique, named Sequential Analysis of MacroMolecules accessibilitY (SAMMY-seq), for the genome-wide mapping of chromatin regions separated by differential accessibility. The method is based on the sequential extraction of multiple chromatin fractions, corresponding to increasingly compacted and less accessible chromatin regions, which are mapped along the genome using high-throughput sequencing. Using SAMMY-seq we analyzed Hutchinson-Gilford progeria syndrome (HGPS) skin fibroblasts and normal control fibroblasts. Additionally we carried out ChIP-seq for the H3K9me3 and H3K27me3 histone modifications and RNA-seq for the characterization of transcriptome changes on the same HGPS and control fibroblasts.
