We have recently described a novel recycling pathway of triglyceride-rich lipoprotein (TRL)-associated apolipoprotein (apo) E in human hepatoma cells. We now demonstrate that not only TRL-derived apoE but also lipoprotein lipase (LPL) is efficiently recycled in vitro and in vivo. Similar recycling kinetics of apoE and LPL in normal and low density lipoprotein receptor-negative human fibroblasts...

OBJECTIVE Overproduction of intestinally derived apoB-48-containing triglyceride-rich lipoproteins (TRLs) (chylomicrons) has recently been described in type 2 diabetes, as is known for hepatic TRL-apoB-100 (very-low-density lipoprotein) production. Furthermore, insulin acutely inhibits both intestinal and hepatic TRL production, whereas this acute inhibitory effect on very-low-density lipoprote...

Since the 1980’s the National Aeronautics and Space Administration (NASA) has used technology readiness level (TRL) as a means to assess the maturity of a particular technology and a scale to compare technologies. In 1999, the Department of Defense (DoD) embraced a similar TRL concept in their programs. The TRL scale is a measure of maturity of an individual technology, with a view towards oper...

Several different carbon-capture technologies have been proposed for use in the cement industry. This paper reviews their attributes, the progress that has been made toward their commercialization, and the major challenges facing their retrofitting to existing cement plants. A technology readiness level (TRL) scale for carbon capture in the cement industry is developed. For application at cemen...

The postprandial responses of apo B48, B100, E and lipids in triglyceride-rich lipoproteins (TRL) to a meal containing one-third of daily energy (39% fat calories) were compared in normolipidemic young men with apo E3/3 and apo E4/3 phenotypes. After the two groups consumed a diet rich in polyunsaturated fat for 15–29 d, their postabsorptive concentrations of TRL triglycerides, apo B48, and apo...

Postprandial triglyceride (TG)-rich lipoproteins (TRLs) transport dietary fatty acids through the circulatory system to satisfy the energy and structural needs of the tissues. However, fatty acids are also able to modulate gene expression and/or induce cell death. We investigated the underlying mechanism by which postprandial TRLs of different fatty acid compositions can induce cell death in hu...

Dyslipidemia is a major risk factor for cardiovascular disease (CVD). Dietary fatty-acid composition regulates lipids and lipoprotein metabolism and may confer CVD benefit. This review updates understanding of the effect of dietary fatty-acids on human lipoprotein metabolism. In elderly participants with hyperlipidemia, high n-3 polyunsaturated fatty-acids (PUFA) consumption diminished hepatic ...
