Long-term correction of hemophilia B through CRISPR/Cas9 induced homology-independent targeted integration
文献摘要:
CRISPR/Cas9-mediated site-specific insertion of exogenous genes holds potential for clinical applications.However,it is still infeasible because homologous recombination(HR)is inefficient,especially for non-dividing cells.To overcome the challenge,we report that a homology-independent targeted integration(HITI)strategy is used for permanent integration of high-specificity-activity Factor Ⅸ variant(F9 Padua,R338L)at the albumin(Alb)locus in a novel hemophilia B(HB)rat model.The knock-in efficiency reaches 3.66%,as determined by droplet digital PCR(ddPCR).The clotting time is reduced to a normal level four weeks after treatment,and the circulating factor Ⅸ(FⅨ)level is gradually increased up to 52%of the normal level over nine months even after partial hepatectomy,demonstrating the amelioration of hemophilia.Through primer-extension-mediated sequencing(PEM-seq),no significant off-target effect is detected.This study not only provides a novel model for HB but also identifies a promising therapeutic approach for rare inherited diseases.
