ß- Caryophyllene Ameliorates Insulin Resistance in Liver of High Fat Diet and Fructose-Induced Type-2 Diabetic Rats

Abstract

Insulin resistance may impact organs that transmit insulin signals, like skeletal muscle, adipose tissue, and the liver. Hyperglycemia and hypertriglyceridemia in the fasting state of type 2 diabetes mellitus are more significantly impacted by insulin resistance in the liver. Hypertriglyceridemia is the culprit behind beta-cell failure in type 2 diabetes. Treating insulin resistance in liver as a primary mechanism of traditional antidiabetic drugs, but unfortunately traditional drugs has unalterable advisory effect. In the present research, insulin resistance in the liver is addressed with the versatile natural phytonutrient beta-caryophyllene to demonstrate effectiveness in managing diabetes. An effective dose of -Caryophyllene taken by non-parental route (200 mg/kg b.wt) was given for 30 days to experimentally induced (high-fat diet and fructose-fed) type-2 diabetic rats to find out whether β-Caryophyllene regulates the IRS-2/akt pathway of insulin signaling. In the liver of diabetic rats, the data demonstrates that ß-caryophyllene treatment significantly increased the mRNA and protein expression of insulin receptor (IR) and GLUT-2. However, there was a significant variation in the mRNA expression of akt and insulin receptor-substrate-2 (IRS-2) between groups. Taking caryophyllene supplements can be beneficial for the control of type 2 diabetes. Studies conducted with this sesquiterpene could have tremendous potential and benefit for the treatment of type 2 diabetes.
