| 2 | CRISPR-CasRx knock-in mice for RNA degradation显示文摘The RNA editing tool CRISPR-CasRx has provided a platform for a range of transcriptome analysis tools and therapeutic approaches with its broad efficacy and high specificity.To enable the application of CasRx in vivo,we established a Credependent CasRx knock-in mouse.Using these mice,we specifically knocked down the expression of Meis1 and Hoxb13 in cardiomyocytes,which induced cardiac regeneration after myocardial infarction.We also knocked down the lnc RNA Mhrt in cardiomyocytes with the CasRx knock-in mice,causing hypertrophic cardiomyopathy.In summary,we generated a Credependent CasRx knock-in mouse that can efficiently knock down coding gene and lnc RNA expression in specific somatic cells.This in vivo CRISPR-CasRx system is promising for gene function research and disease modeling. | Jiacheng Li Dekun Zhu Shengshou Hu Yu Nie | 2022 | Science China(Life Sciences)2022，65，11： | 1 |
