Project description:ChIp-Chip using RNAP II, CREB C/EBPb and cJun antibody in undifferentiated or differentiated keratinocytes
Project description:Undifferentiated and differentiated Keratinocytes (AG1478 treated) were stained with antibody-RNA conjugates (targeting EGFR and ITGA6) to measure protein-based differentiation changes in conjunction with single-cell transcriptomics.
Project description:We report the application of ChIP-seq using an anti-RNA pol II antibody to determine changes in RNAP II occupancy patterns genome-wide. We found that as a result of MYC expression, RNAP II levels increased at both the promoter and gene body regions. This suggests that MYC increases the amount of both the initiation and elongation steps of trasncription globally.
Project description:We report active promoters in five adult mouse tissues - brain, kidney, liver, lung and spleen using ChIP-Seq aganist RNAP-II antibody. We identified 38,639 active RNAP-II transcribed promoters, including 12,270 novel promoters. Of these, 6384 promoters are tissue specific which are CpG poor and contain multiple core promoter elements. By identifying the RNAP-II bound promoter(s) we found that 37% of the protein coding genes use alternative promoters in the five mouse tissues. Roughly 34% of the novel promoters are loacted in CpG-islands suggesting that novel promoters are mostly tissue specific.
Project description:Undifferentiated and differentiated Keratinocytes (AG1478 treated) were stained with antibody-RNA conjugates to measure protein-based diffrentiation changes in conjunction with single-cell transcriptomics. The cells were crosslinked and stained according to the RAID procedure to allow intracellular immunostaining. Antibodies used in this experiment are (TGM1, NOTCH1, KLK6, JAG1, phospho-RPS6, phospho-FAK).
