Abstract:
:The RNA-guided, modified type II prokaryotic CRISPR with CRISPR-associated proteins (CRISPR/Cas9) system represents a simple gene-editing platform with applications in biotechnology and also potentially as a therapeutic modality. The system requires a small guide RNA (sgRNA) and a catalytic Cas9 protein to induce non-homologous end joining (NHEJ) at break sites, resulting in the formation of inactivating mutations, or through homology-directed repair (HDR) can engineer in specific sequence changes. Although CRISPR/Cas9 is a powerful technology, the effects can be limited as a result of nuclease-mediated degradation of the RNA components. Significant research has focused on the solid-phase synthesis of CRISPR RNA components with chemically modified bases, but this approach is technically challenging and expensive. Development of a simple, generic approach to generate chemically modified CRISPR RNAs may broaden applications that require nuclease-resistant CRISPR components. We report here the development of a novel, functional U-replaced trans-activating RNA (tracrRNA) that can be in vitro transcribed with chemically stabilizing 2'-fluoro (2'F)-pyrimidines. These data represent a unique and facile approach to generating chemically stabilized CRISPR RNA.
