Cas13d-mediated isoform-specific RNA knockdown with a unified computational and experimental toolbox [LR-RNA-Seq]

Project description:Alternative splicing is an essential mechanism for diversifying proteins, with different mature RNA isoforms producing different proteins with potentially distinct functions. Two major challenges in characterizing the cellular function of isoforms are the lack of both experimental methods to specifically and efficiently modulate isoform expression and computational tools for complex experimental design. To address these gaps, we developed and methodically tested a strategy which pairs the RNA-targeting CRISPR/Cas13d system with guide RNAs (gRNAs) that overlap exon-exon junctions in the mature RNA. We perform a high-throughput essentiality screen, numerous qPCR assays, and PacBio long read sequencing to affirm that our strategy works to specifically target the unique junctions of isoforms to robustly knockdown their RNA. In parallel, we provide computational tools for experimental design and screen analysis. Considering all possible splice junctions in current GENCODE annotations and our predictions of gRNA efficacy, we estimate that this strategy can target 94% of all human isoforms, including 29,238 protein-coding and 9,638 lncRNA isoforms that are specifically targetable with a gRNA spanning a unique splice junction.

Cas13d experimental viral genome-wide screen identifies regions of RNA vulnerability in SARScov2

Project description:We performed an experimental Cas13d-SARScov2 genome-wide screen to identify gRNAs that would allow Cas13d to degrade the viral RNA. We built mCherry reporter plasmids that express mCherry with a 3kb 3'UTR deriving from the SARScov2 genome. In total we designed 11 reporters covering the entire plus strand of the viral genome and 11 other reporters covering the entire minus strand. Each of the 22 mCherry reporter plasmids carries a U6 expression cassette containing a Cas13d gRNA that targets the 3'UTR of the mCherry reporter. Each reporter is represented by a pool of reporters each containing a different gRNA that targets mCherry 3'UTR for a total average of ~300 gRNA per 3'UTR. The entire pool of 22 reporters, each with a pool of ~300 different gRNAs constitutes a comprehensive set ~6,500 reporters (~ 6,500 different gRNAs) that allowed us to interrogate the entire SARScov2 plus and minus strand viral RNA for regions of vulnerability and targetability. In order to specifically interrogate Cas13d activity an remove the biases that would be introduced in the reporter expression by the presence of a large 3kb 3'UTR we used a case (presence of Cas13d) control (absence of Cas13d) design. Briefly, the ~6,500 reporters were lentiviral transduced in RKO cells, the cells were split in 2 populations, 1 population was transduced with Cas13d and the other serving as control did not. The population expressing Cas13d was FACS sorted in low mCherry (efficient gRNAs) and high mCherry (un-efficient gRNAs) in 2 biological replicates and the genomic DNA of these populations was extracted, gRNAs were PCR amplified and sequenced. For the population that did not express Cas13d, a low mCherry, one high mCherry and unsorted population were sequenced as control libraries.

Differentially expressed genes in the livers of mice exposed to microcystin-LR (MC-LR)

Project description:To explore the molecular mechanisms involved in the toxicity in the livers exposed to MC-LR at the environmental level, the hepatic transcriptome was performed. A total of 210 genes were differentially expressed (P<0.05, |fold change|≥2) in response to MC-LR exposure; among them, 143 genes were significantly upregulated, and 67 genes were downregulated. Pathway enrichment analysis identified the top biological functions associated with the genes differentially expressed in response to MC-LR exposure, which were circadian regulation of gene expression, negative regulation of glucocorticoid receptor signaling pathway, the epoxygenase P450 pathway, regulation of insulin secretion, lipid metabolic process, and cell cycle pathway.
