Additionally, DDAH1 and VAV3 genes were found to be associated with the development of NAFLD, while the target miRNA of circRNA chr3_145845704_145853276_ + and chr3_109562742_109578364_ + may be inhibited to regulate the DDAH1 and VAV3 expressions. This evidence concerns the gene DDAH1 and metabolic dysfunction-associated steatotic liver disease.
