MetAP2 inhibitor treatment of high-fat and -fructose-fed dogs: impact on the response to oral glucose ingestion and a hyperinsulinemic hyperglycemic clamp.

ABSTRACT: We examined the methionine aminopeptidase 2 inhibitor fumagillin in dogs consuming a high-fat and -fructose diet (HFFD). In pilot studies (3 dogs that had consumed HFFD for 3 yr), 8 wk of daily treatment with fumagillin reduced food intake 29%, weight 6%, and the glycemic excursion during an oral glucose tolerance test (OGTT) 44%. A second group of dogs consumed the HFFD for 17 wk: pretreatment (weeks 0-4), treatment with fumagillin (FUM; n = 6), or no drug (Control, n = 8) (weeks 4-12), washout period (weeks 12-16), and fumagillin or no drug for 1 wk (week 17). OGTTs were performed at 0, 4, 11, and 16 wk. A hyperinsulinemic hyperglycemic clamp was performed in week 12; 4 chow-fed dogs underwent identical clamps. Kilocalories per day intake
