Modulation of VLDL triglyceride metabolism

Doctoral Thesis
Obesity is characterized by excessive fat storage and is associated with various diseases like cardiovascular disease (CVD) and type 2 diabetes (DM2), thereby being a serious problem of public health. Excessive energy intake is an important cause of obesity since excess energy is primarily stored as fat. The stored fat is mobilized again during fasting in the form of fatty acids (FA). These FA are re-esterified in the liver in triglycerides (TG) that are secreted in VLDL particles to deliver FA to peripheral tissues where they can be used for energy. One of the current views of the cause of diseases related to obesity is the (mis)handling of TG derived FA. Therefore it is important to understand pathways involved in the uptake, distribution, oxidation and storage of TG. In this thesis we have evaluated the effect of different interventions on VLDL-TG metabolism to gain a better understanding of its complex regulation. For these studies we used APOE*3-Leiden (E3L) and E3L.CETP...Show moreObesity is characterized by excessive fat storage and is associated with various diseases like cardiovascular disease (CVD) and type 2 diabetes (DM2), thereby being a serious problem of public health.

In this thesis we have evaluated the effect of different interventions on VLDL-TG metabolism to gain a better understanding of its complex regulation. For these studies we used APOE*3-Leiden (E3L) and E3L.CETP transgenic mice that have a human-like lipoprotein metabolism and respond to lipid-modifying drugs in a ways similar to humans.Show less
