Abstract

The discovery of the CRISPR systems has enriched the application of gene therapy and biotechnology. As a type of robust and simple toolbox, the CRISPR system has greatly promoted the development of cellular signal sensors at the genomic level. Although CRISPR systems have demonstrated that they can be used in eukaryotic and even mammalian cells after extraction from prokaryotic cells, controlling their gene-editing activity remains a challenge. Here we summarize the advantages and disadvantages of building a CRIRPR-based signal sensor through sgRNA reconstruction, as well as possible ways to reprogram the signal network of cells. We also propose how to further improve the design of the current signal sensors based on sgRNA-riboswitch. We believe that the development of these technologies and the construction of platforms can further promote the development of environment detection, disease diagnosis, and gene therapy by means of synthetic biology.

CRISPR for Genome Editing

Genome editing technologies enable the editing of genes to create or correct mutations. Clustered regularly interspaced short palindromic repeats (CRISPR) are DNA sequences in the genome that are recognized and cleaved by CRISPR-associated proteins (Cas). Here is the latest research on the use of CRISPR-Cas system in gene editing.
