Expansion of the CRISPR/Cas Genome-Sculpting Toolbox: Innovations, Applications and Challenges.

The emergence of the versatile gene-editing technology using programmable sequence-specific endonuclease system (CRISPR-Cas9) has instigated a major upheaval in biomedical research. In a brief span of time, CRISPR/Cas has been adopted by research labs around the globe because of its potential for significant progress and applicability in terms of efficiency, versatility and simplicity. It is a breakthrough technique for systematic genetic engineering, genome labelling, epigenetic and transcriptional modulation, and multiplexed gene editing, amongst others. This review provides an illustrative overview of the current research trends using CRISPR/Cas technology. We highlight the latest developments in CRISPR/Cas technique including CRISPR imaging, discovery of novel CRISPR systems, and applications in altering the genome, epigenome or RNA in different organisms. Finally, we address the potential challenges of this technique for its future use. Development of new CRISPR/Cas systems.
