Shortening the half-life of Cas9 maintains its gene editing ability and reduces neuronal toxicity

Project description:Virus-mediated expression of CRISPR/Cas9 has been actively used for genome editing in animal models of genetic disorders, including neurological diseases, but the consequences of overexpressing bacterial Cas9 in the mammalian brain remain unknown. Through RNA-seq analysis, we found that virus-mediated expression of Cas9 caused systematic changes in genes involved in neuronal functions. We also generated a short-lived version of Cas9, which maintains its genome editing capacity, but significantly alleviates neurotoxicity caused by overexpressed Cas9. Thus, modification of Cas9 by shortening its half-life would help develop CRISPR/Cas9-based therapeutic approaches for treating genetic neurological disorders.

Shortening the Half-Life of Cas9 Maintains Its Gene Editing Ability and Reduces Neuronal Toxicity.

Project description:Virus-mediated expression of CRISPR/Cas9 is commonly used for genome editing in animal brains to model or treat neurological diseases, but the potential neurotoxicity of overexpressing bacterial Cas9 in the mammalian brain remains unknown. Through RNA sequencing (RNA-seq) analysis, we find that virus-mediated expression of Cas9 influences the expression of genes involved in neuronal functions. Reducing the half-life of Cas9 by tagging with geminin, whose expression is regulated by the cell cycle, maintains the genome editing capacity of Cas9 but significantly alleviates neurotoxicity. Thus, modification of Cas9 by shortening its half-life can help develop CRISPR/Cas9-based therapeutic approaches for treating neurological disorders.

NANOS2-binding regulates mRNA half-life and key spermatogonial stem cell self-renewal pathways

Project description:We have identified NANOS2 bound targets transcriptome wide by employing CRAC and RNA-seq in mouse SSCs. We have determined the average mRNA half-life in SSCs by SLAM-seq. By comparing CRAC and SLAM-seq datasets, we have demonstrated that NANOS2 binding reduces mRNA stability in SSCs.

Cell cycle mRNA half-life profiling.

Project description:mRNA half-life profiling in the bacterium Caulobacter crescentus was performed in synchronized cells collected from different stages of the cell cycle including swarmer cells, stalk cells (45 min post synchrony), and predivisional cells (90 min post synchrony). For each cell population, transcription was disrupted by the antibiotic rifampicin, and RNA samples were collected at different time points to measure the mRNA half-lives.

Half-life determination for human B-cells (BL41)

Project description:RNA was labeled in BL41 cells by culturing cells for 60 min in media containing 100µM 4sU. Tc-RNA was separated into nt- and p-RNA. All three RNA subsets were subjected to microarray analysis. Only probe sets providing present calls in all RNA samples/subsets were included into the analysis We used microarrays to determine half-lives of mRNAs expressed in BL41 cells Keywords: Determination of mRNA half-life in human B-cells

BR-body mutant mRNA half-life profiling.

Project description:BR-body mutant strains were globally profiled for mRNA half-lives using rifampicin treatment followed by RNA-seq. JS38 (wild type) was compared to JS221 (lacking the intrinsically disordered CTD and unable to form BR-bodies), JS233 (unable to recruit degradosome components into BR-bodies), and JS299 (active site mutant of RNase E).
