In the present study, we investigate the effect of the water extract of Dendropanax morbifera leaves (DLE) on anti-diabetic
activity in the diabetic db/db mice. 6-week-old male db/m+ and 5 groups of db/db mice were treated with metformin or
DLE for 6 weeks, db/m+ group (normal), db/db group (control), metformin group (positive control, 200 mg/kg) and the
DLE groups (50, 100, 200 mg/kg). The oral administration of DLE or metformin significantly lowered serum glucose, insulin,
HbA1c, c-peptide and serum lipid levels (TG, TC) in db/db mice. Additionally, the safety of 6 weeks administration of DLE was
confirmed when considering that the level of AST, ALT and BUN in serum were within the normal range. Histological analysis
with H&E staining indicated that DLE treated group showed the higher number of hepatic nucleus compared to the db/db
group. To understand the molecular mechanism of DLE, the expression level of genes associated with diabetes was measured
in liver and muscle tissue. The expression of glucose metabolism and transport genes (glucokinase, glucose transporter type-2
and 4) and glycogen synthase of db/db mice was increased by DLE. On the other hand, DLE treatment resulted in decreased
expression level of gluconeogenesis related genes such as glucose-6-phosphatase, phosphoenolpyruvate and carboxykinase.
These results suggest that DLE may have the possibility to ameliorate type-2 diabetes. Therefore, DLE could be extensively used
as a functional food for mitigating type-2 diabetes.
