　　CRISPR interference or CRISPR-on uses denuclease activity Cas9 (dCas9) and transcription effect fusion protein and a variety of specific guide RNA (gRNA)-dCas9 fusion systems to block or activate the transcription technology of target genes. The Liu Dong research team of the School of Life Sciences published a research paper titled "Non-catalytic Cas9-mediated gene regulation of transcriptional activity in Caenorhabditis elegans and Clostridium reesei" in the journal Cell Research on March 27.

　　The fusion system can effectively change the development of the inner ear of zebrafish and the expression of genes related to nematode resistance. This method is not only suitable for the expression regulation of protein-coding genes, but also theoretically can be used for the regulation of non-coding RNA expression and modification of special DNA sites. Below method. From
