Research Abstract |
Leptin (L)/amylin (A) co-administration significantly reduced food intake and body weight in leptin-resistant diet-induced obesity mice, while administration of L or A alone had no effects. L/A co-administration enhanced insulin sensitivity associated with decreased tissue triglyceride content and increased α2 AMP-activated protein kinase (AMPK) activity in skeletal muscle. This study demonstrates the beneficial effect of L/A co-administration on glucose and lipid metabolism in DIO mice, indicating the possible clinical usefulness of L/A co-administration as a new anti-diabetic treatment in obesity-associated diabetes.
