Project description:~1500 K562 cells expressing dCas9-KRAB were profiled on the 10x Genomics 3' v3 droplet-based scRNA-seq platform. The resulting library was sequenced on the Illumina and Ultima sequencing platforms.
Project description:Comparisons of molecular phenotypes across primates provide unique information to understand human biology and evolution and single-cell RNA-seq CRISPR interference screens are a powerful approach to analyze them. Here, we generate and validate three human, three gorilla and two cynomolgus iPS cell lines that carry a dox-inducible KRAB-dCas9 construct in the AAVS1 locus. We show that despite variable expression levels of KRAB-dCas9 among lines, comparable downregulation of target genes and comparable phenotypic effects are observed in a single-cell RNA-seq CRISPR interference screen. Hence, we provide valuable resources for performing and further extending CRISPRi screens in human and non-human primates.

Project description:Infinium MethylationEPIC (850K) BeadChip data for wildtype SUM159 cells (2 replicates), SUM159 cells transfected with plV-KRAB (dCas9 CRISPRi system; 3 replicates), and SUM159 cells transfected with dCas9-KRAB and 4 targeting gRNAs against the ZEB1 promoter (3 replicates)
Project description:We report the generation of CRISPR-dCas9 DNA methyltransferases to mediate targeted DNA methylation. Using the dCas9-BFP-DNMT3A and dCas9-BFP-DNMT3B methyltransferases, we have demonstrated that these two methyltransferase can mediate targeted methylation in three human genes tested: uPA, TGFBR3, and CDKN2A in human HEK293T cells. We also showed that these methyltransferases could mediate gene inhibition. five samples co-transfected with five uPA sgRNAs and each of the four dCas9 fusions, or control transfection with pUC19 plasmid
