When utilizing a KO mouse model, you want to see if introducing the dystrophin gene can rescue the DMD mouse model. Propose a mechanism to (re)introduce dystrophin back into the KO mouse.
CRISPR can be used to reintroduce dystrophin back into the KO mouse
CRISPR stands for Clustered Regularly Interspaced Short Palindromic Repeats and is used to for gene editing
CRISPR/Cas-mediated genome editing has been shown to permanently correct DMD mutations and restore dystrophin function in mouse models
Germline editing by injecting zygotes with CRISPR/Cas9 editing component was first done in mdx mice by correcting the mutated exon 23
Postnatal editing of mdx mice was then achieved using recombinant adeno-associated virus to deliver CRISPR/Cas9 genome editing components and correct the dystrophin gene by skipping or deleting the mutated exon 23 in vivo
Germline and postnatal CRISPR/Cas9 editing approaches both successfully restored dystrophin function in the mice and same technique can be used for KO mouse model
