The results showed that IR tyrosine phosphorylation ( pIR ) was reduced by 42 % in MSG - obese mice ( MSG , 6 . 7 +/- 0 . 2 arbitrary units ( a . u . ) ; control , 11 . 5 +/- 0 . 4 a . u . ) ; on the other hand , exercise training increased pIR by 76 % in MSG mice without affecting control mice ( MSG , 11 . 8 +/- 0 . 3 ; control , 12 . 8 +/- 0 . 2 a . u . ) .
