Coordinated regulation of fat-specific and liver-specific glycerol channels, aquaporin adipose and aquaporin 9.

In the present study, we cloned the coding and promoter regions of mouse aquaporin 9 (AQP9), a liver-specific glycerol channel.

Insulin deficiency induced by streptozotocin resulted in increased hepatic AQP9 mRNA.

In cultured hepatocytes, insulin downregulated AQP9 mRNA.

|
The AQP9 promoter contained the negative insulin response element TGTTTTC at -496/-502, similar to the promoter of the AQPap/7 gene.

|
In contrast, in insulin-resistant db+/db+ mice, AQPap/7 mRNA in fat and AQP9 mRNA in liver were increased, despite hyperinsulinemia, with high plasma glycerol and glucose levels.

Our results indicate that coordinated regulations of fat-specific AQPap/7 and liver-specific AQP9 should be crucial to determine glucose metabolism in physiology and insulin resistance.

Compared with control mice, plasma levels of glycerol and triglycerides were markedly increased in AQP9(-/-) mice, whereas glucose, urea, free fatty acids, alkaline phosphatase, and cholesterol were not significantly different.

|
Obese Lepr(db)/Lepr(db) AQP9(-/-) and obese Lepr(db)/Lepr(db) AQP9(+/-) mice showed similar body weight, whereas the glycerol levels in obese Lepr(db)/Lepr(db) AQP9(-/-) mice were dramatically increased.

|
Consistent with a role of AQP9 in hepatic uptake of glycerol, blood glucose levels were significantly reduced in Lepr(db)/Lepr(db) AQP9(-/-) mice compared with Lepr(db)/Lepr(db) AQP9(+/-) in response to 3 h of fasting.

Hepatic glycerol uptake is facilitated by aquaporin-9 (AQP9), a broad-selectivity neutral solute channel, and represents an insulin-regulated step in supplying gluconeogenesis with glycerol.
