The Effect of Six Weeks-Voluntary Wheel Running on Brain Amyloid Beta (1-42) Levels of Diabetic Rats

Abstract

Background : Amyloid Beta (1-42) is derived from amyloid precursor protein and plays a critical role in AD pathogenesis. The purpose of this study was to investigate the effect of 6 weeks of voluntary wheel running on brain Amyloid beta (1-42) in the diabetic rats induced with alloxan.Materials and Methods : 28 male rats weight 185±1 were assigned randomly to 4 groups (N=7): normal control (C), training (T), control-diabetic (CD) and diabetic-training (DT). Diabetes was induced with injecting Alloxan (120 mg/kg dissolved in saline) intraperitoneal.Results : 6 weeks of voluntary wheel running decreased the cortex Aβ1-42 in T and DT groups. Aβ1-42 levels significantly decreased in the T and DT in compare with C and CD (p
