CRISPR/Cas9 Technology: Applications and Human Disease Modeling

The CRISPR/Cas9 system development has revolutionized the field of genome engineering through the efficient creation of targeted breaks in the DNA of almost any organism and cell type, opening an avenue for a wide range of applications in biomedical research and medicine. Apart from gene edition through knock-in or knock-out approaches, CRISPR/Cas9 technology has been used for many other purposes, including regulation of endogenous gene expression, epigenome editing, live-cell imaging of chromosomal loci, edition of RNA and high-throughput screening. With all those technological improvements, CRISPR/Cas9 system has broadened the number of alternatives for studying gene function and the generation of more accurate disease models. Although many mechanistic questions remain to be answered and several challenges have yet to be addressed, the use of CRISPR/Cas9-based genome engineering technologies will increase our knowledge of disease processes and their treatment in the near future.
