摘要

肌球蛋白轻链3 （MYL3）基因编码心室必需轻链异构体，该异构体是肌球蛋白过桥动力学的重要调节剂。MYL3的变异是肥厚性心肌病和扩张性心肌病合并心力衰竭和心源性猝死（SCD）的原因。为了进一步阐明MYL3在心肌病发病机制中的作用，我们利用CRISPR/Cas9系统创建了MYL3敲除的人胚胎干细胞系。值得注意的是，这种myl3敲除细胞系保持了正常的形态、多能性和核型。该资源为调查与myl3相关的健康和疾病提供了有价值的工具。

Generation of a MYL3 knockout stem cell line (WAe009-A-1H) by episomal vector-based CRISPR/Cas9 system

The Myosin light chain 3 (MYL3) gene encodes the ventricular essential light chain isoform, which is an important modulator of sarcomeric myosin cross-bridge kinetics. Variants in MYL3 are a cause of hypertrophic cardiomyopathy and dilated cardiomyopathy with cardiac failure and sudden cardiac death (SCD). To further elucidate the involvement of MYL3 in the pathogenesis of cardiomyopathies, we have created a MYL3 knockout human embryonic stem cell line using the CRISPR/Cas9 system. Notably, this MYL3-knockout cell line retains normal morphology, pluripotency, and karyotype. This resource provides a valuable tool for investigating MYL3-related health and disease.
