The disclosure relates to double-stranded ribonucleic acid (dsRNA) compositions targeting the MARC1 gene, and methods of using such dsRNA compositions to alter (e.g., inhibit) expression of MARC1.

Provided are modified tobacco plants having reduced nitrate levels and tobacco products generated from the modified tobacco plants having reduced tobacco specific nitrosamines (TSNAs). Also provided are methods of reducing TSNAs in tobacco products by altering the gene expression of the nitrate assimilation pathway

The present disclosure relates to an RNAi agent targeting a mitochondrial amidoxime reducing component 1 (MARC1) gene and a use thereof, specifically, the present disclosure relates an RNAi agent including an antisense strand having sequence complementarity to a MARC1 mRNA sequence and a sense strand having sequence complementarity to the antisense strand, and a pharmaceutical composition including the RNAi agent for preventing or treating liver disease, such as non-alcoholic fatty liver disease.

The present disclosure relates to RNAi agents, e.g., double stranded RNAi agents, able to inhibit mitochondrial amidoxime reducing component 1 (MARC1) gene expression. Also disclosed are pharmaceutical compositions that include MARC1 RNAi agents and methods of use thereof. The MARC1 RNAi agents disclosed herein may be conjugated to targeting ligands, including ligands that comprise N-acetyl-galactosamine, to facilitate the delivery to hepatocyte cells. Delivery of the MARC1 RNAi agents in vivo provides for inhibition of MARC1 gene expression. The RNAi agents can be used in methods of treatment of diseases, disorders, or symptoms mediated in part by MARC1 gene expression, including nonalcoholic steatohepatitis (NASH), nonalcoholic fatty liver disease (NAFLD), alcoholic fatty liver disease, autoimmune hepatitis, hepatic fibrosis, cirrhosis, elevated blood cholesterol levels, hypertriglyceridemia, liver disease, and/or other MARC1-related disease.
