NOS2 and metabolic syndrome: Interestingly, treatment with antibiotics rescued dyslipidemia (Kuno et al., 2018) in iNOS−/− mice via reduction in the expression of genes involved in fatty acid synthesis (Zarrinpar et al., 2018) in the liver and adipose tissue and of lipid uptake in the adipose tissue, while the expression of genes involved in the lipid efflux was augmented in the liver and intestine.
