Cardiac expression of the microsomal triglyceride transport protein protects the heart function during ischemia

The microsomal triglyceride transport protein (MTTP) is critical for assembly and secretion of apolipoprotein B (apoB)-containing lipoproteins and is most abundant in the liver and intestine. Surprisingly, MTTP is also expressed in the heart. Here we tested the functional relevance of cardiac MTTP expression.We combined clinical studies, advanced expression analysis of human heart biopsies and analyses in genetically modified mice lacking...
