Beneficial effects of n-3 polyunsaturated fatty acids on adiponectin levels and AdipoR gene expression in patients with type 2 diabetes mellitus: a randomized, placebo-controlled, double-blind clinical trial
Introduction There is evidence that n-3 polyunsaturated fatty acids ( n-3 PUFAs ) exert beneficial effects to improve type 2 diabetes mellitus ( T2DM ) , but its complications remain poorly understood . Hypoadiponectinemia is one of the important mechanisms responsible for T2DM which necessitates developing novel therapeutic strategies . We aim ed to determine the effect of n-3 PUFA supplementation on circulating adiponectin and mRNA expression of adiponectin receptors ( AdipoR1 , AdipoR2 ) and Sirt-1 in T2DM patients . Material and methods A r and omized , double-blind , placebo-controlled trial of 10-week follow-up of n-3 PUFAs ( 2.7 g/day ) vs. placebo in T2DM patients ( n = 88 ) was conducted . In detail , T2DM patients ( n = 44 ) were treated with n-3 PUFAs and the remainder received placebo .  Anthropometric and metabolic characteristics were assessed in all participants .  Circulating level of adiponectin and mRNA expression of AdipoR1 , AdipoR2 and Sirt-1 were measured in peripheral blood mononuclear cells ( P BMC ) using real-time polymerase chain reaction before and after the intervention . Results It was found that n-3 PUFAs  increased AdipoR1 gene expression ( fold change = 1.321 in n-3 PUFAs vs. 1.037 in placebo ) and AdipoR2 mRNA ( fold change = 1.338 in n-3 PUFAs vs. 1.034 in placebo ) . No significant changes were observed for Sirt-1 expression . The serum level of adiponectin significantly ( p = 0.035 ) increased in n-3 PUFAs ( 5.09 to 5.58 μg/ml ) but remained unchanged in the placebo group . Conclusions Daily supplementation with n-3 PUFAs ( 2.7 g ) was effective to significantly improve gene expression of AdipoR1 and AdipoR2 and the serum level of adiponectin in T2DM patients . Therefore , n-3 PUFAs might emerge as an adjuvant for current antidiabetic therapies . However , confirmatory long-term studies are required
