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.
肝纤维化是各种致病因素作用于肝脏引起的组织损伤和修复的病理反应。目前,尚无有效的抗纤维化特异性治疗方法。成簇规律间隔短回文重复序列(CRISPR)/CRISPR相关蛋白9(dCas9)系统是新一代基因编辑技术。CRISPR/dCas9系统为研究位点特异性转录调控提供了一个平台,在基因转录激活方面具有高效性以实现强大功能。该系统有望通过作用于肝纤维化效应细胞来治疗肝纤维化。然而,这项新技术存在一些挑战,如靶向、脱靶位点的大结构变异以及靶向递送效率等问题。在本综述中,我们阐述了CRISPR/dCas9系统在肝纤维化治疗中可能产生的潜在影响,并描述了可能遇到的挑战。
