Project description:Treatment with the histone deacetylase inhibitor trichostatin a (TSA) changes the radial positioning of the CFTR gene in HeLa S3 cells. The gene relocates from the nuclear periphery to the nuclear interior. In Calu-3 cells the gene is located in the nuclear interior. To identifiy potential regulatory elements for the positioning of CFTR, the histone h3 and h4 acetylation patterns of untreated and TSA-treated HeLa S3 and untreated Calu-3 cells were determined by ChIP-chip. A CTCF site close to the CFTR promoter displayed consistent histone H3 hyperacetylation in TSA treated HeLa S3 cells and Calu-3 cells. Four Agilent 4x 44K DNA-chips (DNA-Chips: REP_1 - REP_4). HeLa untreated and TSA treated: H3ac/H3pan (Cy5/Cy3): hybridized together on four sectors - 1x regular 3x dye swap; H4ac: 3 sectors, respective H3pan reference on different sectors on the same DNA-chips (labeled with the identical fluorophore). Calu-3: H3ac/h3pan: one sector each on the same DNA-chip (labeled with the identical fluorophore) H4ac/H3pan: two sectors each on the same DNA-chips (two each on two DNA-Chips, labeled with the identical fluorophore)
Project description:STAT1 ChIP-chip performed on Human Hela S3 Cells for three different platforms. Nimblegen ENCODE arrays which comprise 50mer oligonucleotides spaces every 38bps (overlapping by 12nts) (5 biological replicates), custom maskless array tiling most of ENCODE with 50mer oligonucleotides end-to-end (3 biological replicates) and custom maskless array tiling most of ENCODE with 36mer oligonucleotides end-to-end (2 biological replicates). The chromatin-immunoprecipitation protocol is the same for all samples, however the labelling and hybridization protocols differ between Nimblegen and custom maskless arrays.
