We chose the Tet family genes as targets germline transmission of multiple to demonstrate the feasibility of CRISPR- Cas–mediated mutagenesis in rat. The gene mutations in rat using three Tet genes encode proteins with DNA hydroxymethylase functions and CRISPR-Cas systems play key roles in the regulation of many important biological processes . The Cas9 endonuclease functions either with a To the Editor: The laboratory rat is an important model combination of a short crRNA and a trans- CRISPRs are clustered, regularly interspaced, organism for human disease research. activating crRNA (tracrRNA), or with a short palindromic repeats present in many Several technologies including zinc finger chimeric single guide RNA (sgRNA).
