Hyperlipidemia is an important risk factor for coronary heart disease. Chadwick and colleagues report significantly reduced blood lipid levels following CRISPR-based genome editing in mice to introduce loss-of-function mutations in ANGPTL3, a lipoprotein lipase inhibitor. The treatments were effective in both healthy and Lplr−/− mice and comparable to PCSK9-targeted genome editing, without causing off-target mutations.
高脂血症是冠心病的一个重要危险因素。Chadwick 及其同事报道,通过 CRISPR 为基础的基因编辑使小鼠体内 ANGPTL3 产生失活突变,从而抑制脂蛋白脂肪酶,可显著降低血脂水平。这些治疗方法在健康和 Lplr−/−小鼠中均有效,且与 PCSK9 靶向基因编辑相当,而不会引起脱靶突变。
