Perturbation of glycerol metabolism in hepatocytes from n3-PUFA-depleted rats.

Abstract:

:Second generation n3-PUFA-depleted rats represent a good animal model of metabolic syndrome as they display several features of the disease such as liver steatosis, visceral obesity and insulin resistance. The goal of our study was to investigate the influence of n3-PUFA deficiency on hepatic glycerol metabolism. Aquaglyceroporin 9 (AQP9) allows hepatic glycerol transport and consequently contributes to neoglucogenesis. AQP9 knockout mice display hypertriacyl-glycerolemia, one of the hallmarks of the metabolic syndrome. Our data show reduced AQP9 expression at the protein level in n3-PUFA-depleted rats, without any changes at the mRNA levels. [U-¹⁴C]glycerol uptake was increased in hepatocytes from n3-PUFA-depleted animal cells. The apparent discrepancy between decreased AQP9 protein expression, and increased [U-¹⁴C]glycerol uptake could be explained by an observed increase in glycerol kinase activity.
