Abstract

Hepatic fibrosis is a pathological reaction of tissue damage and repair caused by various pathogenic factors acting on liver. At present, there is no effective anti-fibrotic specific therapy. Clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 (dCas9) system is a new generation of gene editing technology. The CRISPR/dCas9 system provides a platform for studying site-specific transcriptional regulation, which has high efficiency in gene transcriptional activation for achieving robust. This system holds promise for hepatic fibrosis therapy via acting on liver fibrosis effector cells. However, there are some challenges associated with this novel technology, such as large structural variants at on-target, off-target sites, and targeted delivery efficiency. In this review, we present the potential implications and describe the challenges of CRISPR/dCas9 system that might be encountered in hepatic fibrosis therapy.

Keywords: CRISPR/dCas9; Gene therapy; HSCs; Hepatic fibrosis; Targeted delivery.
