Project description:Inactivation of Suv420h1 in MuSC lead to increased transcription and replication collision thereby caused accumulation of RNA:DNA hybrids. This study profiles the R-loops in Ctrl and Suv420h1m mutant MuSCs.
Project description:H4K20me1/2/3 is dynamically regulated during cell cycle to maintain the genomic stability. Here, we found that depletion of H4K20 di-methyltransferase Suv420h1 in mouse adult MuSCs leads to strong accumulation of H4K20me1 specifically in S phase. In response to it, the transcription activity is increased upon Suv420h1 depletion. To investigate which genomic regions and how the transcription are regulated by Suv420h1 in MuSC, we performed Cut&Run of H4K20me1 and RNA polymerase II Ser2P in control and Suv420h1 inactivated MuSCs.
Project description:To profile the nascent transcription activity including coding genes and eRNAs, we performed precision nuclear run-on sequencing (PRO-Seq) in control and Suv420h1 mutant MuSC
Project description:This study profiles RNA:DNA hybrid formation in human and mouse cell lines. DRIPc-seq (strand-specific R-loop mapping) was performed on human NT2 cells and mouse 3T3 cells. DRIP-seq (R-loop mapping) was performed on human NT2 and K562 and mouse E14 and 3T3 cell lines. MethylC-seq and RNA-seq were performed on NT2.
Project description:PREX2 truncating mutations occur in melanoma. We used microarray based gene expression profiling to compare expression patterns between cells harboring Suv420h1 knockout and PREX2 mutant expressing Spontaneously immortalized MEFs from either wt or Suv420h1 knockout mice were used. Wt MEFs were transduced with lentivirus to express indicated PREX2 mutants. Suv420h1 ko MEFs were reconstituted either with control GFP or Suv420h1-GFP fusion. Total RNA was isolated and subjected to analysis
