ACOX1 and liver dysplastic nodule: Specificity, Further integration analyses have identified that the linoleic acid metabolism and fatty-acids β-oxidation are significantly inhibited during DN pathogenesis and progression, the transporter protein ABCD3, the fatty acyl-CoA activated enzymes ACOX1, ACOX2, and ACOX3, and some corresponding metabolites such as 13′-HODE, stearidonic acid, docosahexaenoic acid, (±)10(11)-EpDPA were also significantly reduced.
