Project description:We report the genome-wide occupancy of Hoxc4-au by using chromatin isolation after RNA purification (CHIRP) in eWAT-derived preadipocytes
Project description:We performed Chromatin Isolation by RNA Purification (ChIRP) of SRA and ChIP of p68 following by high-throughput sequencing in NTERA2 cell line. We find that SRA localizes with p68 genome-wide at genes whose function is involved in embryonic development. SRA ChIRP and p68 ChIP of triplicate samples.
Project description:We employed ChIRP in combination with proteomic strategy to systematically discover HOTAIR-interacting proteins. Three independent biological replicates of ChIRP-MS experiment were performed, alongside negative controls.
Project description:Long intergenic noncoding RNAs (lincRNAs) are key regulators of chromatin state, yet the nature and sites of RNA-chromatin interaction are mostly unknown. Here we introduce Chromatin Isolation by RNA Purification (ChIRP), where tiling oligonucleotides retrieve specific lincRNAs and bound protein and DNA sequences, which are enumerated by deep sequencing. ChIRP-seq of two lincRNAs reveal that RNA binding sites in the genome are focal, sequence-specific, and numerous. Human telomerase RNA TERC occupies telomeres and Wnt pathway genes. HOTAIR lincRNA preferentially binds a GA-rich homopurine DNA motif to nucleate broad domains of Polycomb occupancy and histone H3 lysine 27 trimethylation. HOTAIR occupancy occurs independently of EZH2, defining the order of RNA guidance of Polycomb occupancy. ChIRP-seq is readily applicable to numerous RNAs in different cell types and biological states, thus enabling the study of RNA regulation of chromatin and gene expression at a genomic scale. Examination of 3 lincRNAs in 5 cell types
Project description:We report the application of ChIRP-seq on examination of LncMyoD binding sittes in differentiated myotubes We observed the global binding sites of LncMyoD in differentiated myotubes.
Project description:We aimed to clarify the possible functional role of hsa_circ_0000563 in coronary artery disease. Therefore, the ChIRP-MS was conducted to explore the interaction between BTBD7_hsa_circ_0000563 and proteins on a genomic scale in human peripheral blood mononuclear cell (PBMC). This project is the raw files of the proteins bound to hsa_circ_0000563 found by ChIRP-MS in PBMC.
Project description:The number of methods used to study RNA-protein interactions in plants is currently relatively limited. The RNA-centric approach, starting with RNA of interest, brings several difficulties, especially when the RNA belongs to the less abundant RNAs. These methods for identification of RNA-interacting proteins used to be developed for different model systems, however, their application in plants is delayed. The Comprehensive identification of RNA-binding proteins by mass spectrometry (ChIRP-MS) method was originally developed for mammalian cells. This work describes the modified ChIRP-MS procedure applicable in Arabidopsis thaliana. All steps were optimized for the telomerase RNA which was recently described as a low-abundant RNA. Following this optimization procedure, it is possible to use ChIRP-MS as a screening method for the identification of candidate proteins interacting with the target RNA.
