The molecular mechanism of CRISPR/Cas9 system and its application in gene therapy of human diseases
CRISPR/Cas system is an adaptive immune system that confers resistance to exogenous virus or plasmid in bacteria and archaea. In recent years, the booming CRISPR/Cas9 genome editing technology modified from typeⅡCRISPR/Cas adaptive immune system has been widely applied to various research fields of life science and led to revolu-tionary changes. In this review, we summarize the origin and development of CRISPR/Cas9 genome editing technology as well as its applications in life science research. We focus on the latest application of this system in gene therapy of human diseases and the associated side/off-target effects, which may provide references for researchers in related areas.
