Efficient Gene Knock-out and Knock-in with Transgenic Cas9 in Drosophila
Bacterial Cas9 nuclease induces site-specific DNA breaks using small gRNA as guides. Cas9 has been successfully introduced into Drosophila for genome editing. Here, we improve the versatility of this method by developing a transgenic system that expresses Cas9 in the Drosophila germline. Using this system, we induced inheritable knock-out mutations by injecting only the gRNA into embryos, achie...
متن کاملTransposon-generated ‘knock-out’ and ‘knock-in’ gene-targeting constructs for use in mice
The conventional technique for targeted mutation of mouse genes entails placing a genomic DNA fragment containing the gene of interest into a vector for fine mapping, followed by cloning of two genomic arms around a selectable neomycin-resistance cassette in a vector containing thymidine kinase [1]; this generally requires 1-2 months of work for each construct. The single 'knock-out' construct ...
متن کاملCRISPR/Cas9-Mediated Gene Knock-Down in Post-Mitotic Neurons
The prokaryotic adaptive immune system CRISPR/Cas9 has recently been adapted for genome editing in eukaryotic cells. This technique allows for sequence-specific induction of double-strand breaks in genomic DNA of individual cells, effectively resulting in knock-out of targeted genes. It thus promises to be an ideal candidate for application in neuroscience where constitutive genetic modificatio...
متن کاملConditional gene knock-down by CRE-dependent short interfering RNAs.
Short interfering RNAs (siRNAs) are short (21-23 nt) double-stranded RNAs that direct the sequence-specific degradation of corresponding mRNAs, resulting in suppression of gene activity. siRNAs are powerful tools for gene functional analysis in mammals. Chemically synthesized siRNAs permit transient gene repression but preclude inhibition of stable gene products as well as long-term phenotypic ...
متن کاملGlucocorticoid-stimulated gene expression knocked out by knock-in mutation.
Glucocorticoid receptors (GRs) are ligand-dependent transcription modulators. They belong to a superfamily of nuclear hormone receptors including receptors for steroid and thyroid hormones, retinoids, vitamin D and peroxisomal activators among others (1). The receptor can be divided into three functional domains: (1) an N-terminal activation domain (AF1 or t1); (2) a central DNA-binding domain;...
