Abstract
Cytoplasmic fatty acid-binding protein (FABP) was assayed immunochemically in hearts from rats with insulin-dependent (IDDM) or non-insulin-dependent diabetes mellitus (NIDDM). FABP contents were 34% higher in IDDM and 103% higher in NIDDM hearts than in respective age-matched controls. FABP levels returned to control values when islets of Langerhans were transplanted into diabetic IDDM animals. In the diabetic hearts the activity of fructose-6-phosphate kinase decreased (IDDM and NIDDM animals), while that of 3-hydroxyacyl-CoA dehydrogenase increased (NIDDM animals only). These data indicate that experimental diabetes induces a marked increase of the FABP content of rat heart and suggests that this protein is involved in the enhanced fatty acid utilization by the diabetic heart.Entities:
