Abstract: | CRISPR/Cas9 system is a natural immune system in prokaryotes protecting them from infectious viral or plasmid DNA invading the cells. This RNA-guided system can act as powerful tool for introducing genomic alterations in eukaryotic cells with high efficiency. In the present study, Rig-Igene is taken as model gene to study the efficiency of CRISPR/Cas9 system induced gene deletion in primary fibroblast cell culture. Rig-I(retinoic acid-inducible gene-1) is involved in regulating immune response in mammals. In this study, we optimized the CRISPR/Cas9 method for knocking out Rig-Igene in Goat primary fibroblasts by using a NHEJ pathway. Cells were screened for inactivation of the Rig-Igene and two positive clones were found out of thirty colonies screened. Thus, cells containing Rig-Igene inactivation could be achieved by CRISPR/Cas9 in goat fibroblast cells. |
