The invention relates to double-stranded ribonucleic acid (dsRNA) compositions targeting the ANGPTL3 gene, as well as methods of inhibiting epression of ANGPTL3 and methods of treating subjects having a disorder of lipid metabolism, such as hyperlipidemia or hypertriglyceridemia, using such dsRNA compositions.本發明涉及靶向ANGPTL3基因的雙股核糖核酸(dsRNA)組成物,以及使用此種dsRNA組成物而抑制ANGPTL3表現的方法及治療具有脂肪代謝障礙,諸如高血脂症或高三酸甘油酯血症之個體的方法。
