Project description:The objective of the study is to profile histone H3 lysine nine di-methylation (H3K9me2) in Arabidopsis thaliana and to correlate it with DNA methylation. We constructed a high-resolution genome-wide map of H3K9me2 methylation by using native chromatin immunoprecipitation coupled with HD2 whole genome Nimblegen microarrays. Three replicas were performed for the native ChIP. As a control, one replica of ChIP isolated from crosslinked tissue was used.
Project description:Chromatin immunoprecipitation was performed using antibodies against CTCF and formaldehyde crosslinked chromatin from K562 Chromatin cells. The immunoprecipitated DNA was amplified, fluorescently labeled and hybridized to a 391K element tiling array based on NCBI35 build of the human genome (hg17) that contains overlapping 50-mer oligonucleotides, positioned at every 38 basepairs (bp) throughout the ENCODE regions. Keywords: ChIP-chip
Project description:We performed a set of microarray and chromatin-immunoprecipitation (ChIP)-chip experiments using siRNA against the (pro)renin receptor ((P)RR), stable overexpression of PLZF, the PLZF translocation inhibitor genistein and the specific V-ATPase inhibitor bafilomycin to dissect transcriptional pathways downstream of the (P)RR. In this dataset, we include the ChIP-chip data obtained from PLZF overexpressing KELLY cells, from PLZF overexpressing HEK293T cells and from KELLY as well as HEK293T cells both stably transfected with an insertless control vector.

Project description:G-quadruplex (G4) structures exist in single-stranded DNA of chromatins and regulate genome function. However, the native chromatin G4 landscape in living cells has yet to be fully characterized. Herein, we fused BG4 antibody and GFP-tag to construct a live-cell G4 identifier (LiveG4ID). We first displayed its function as a high-specificity chromatin G4 probe in living cells by Dox-induced expression LiveG4ID in HEK293T cells and detecting its cellular localization, biocompatibility and G4-binding specificity. By coupling LiveG4ID with CUT&Tag technology, we established LiveG4ID-seq, a method for mapping native chromatin G4 landscape in living cells. LiveG4ID-seq can identify more chromatin G4 motifs than traditional CUT&Tag and ChIP-seq methods. Using LiveG4ID-seq, we profiled the dynamic landscape of chromatin G4 structures during the cell cycle. These data demonstrate the capacity of LiveG4ID-seq to profile a more accurate G4 landscape in living cells and promote future study on chromatin G4 structures.
