The development of the remnant like particle (RLP) method for conveniently measuring serum remnant lipoprotein levels in 1993 promoted much research on atherogenic significance and metabolism of remnant lipoproteins. This research brought about many results as the following. A novel apolipoprotein B48 receptor incorporating remnant lipoproteins into macrophages in arterial wall was discovered a...

We observed fibers immunoreactive (IR) to serotonin (5-HT), the myomodulins (MMs), and FMRFamide on the I7-I10 complex in the marine mollusk Aplysia californica. The I7-I10 muscle complex, which produces radula opening, is innervated primarily by one motor neuron, B48. B48 is MM-IR and synthesizes authentic MM(A). When B48 is stimulated in a physiological manner, cAMP levels are increased in op...

The aryl hydrocarbon receptor (AhR) is a transcription factor that is activated by dioxin and related xenobiotics. Although the activation of AhR is inhibited by tyrosine kinase inhibitors, the molecular mechanism has not been clarified. In the current study, the inhibitory mechanisms of several inhibitors of tyrosine kinase, herbimycin A, genistein, and tyrphostin B48, on AhR activation was an...

Clinical studies in adults indicate there is a positive and significant association between insulin resistance, dyslipidaemia, fasting intestinally derived lipoproteins [via apoB48 (apolipoprotein B48)] and visceral fat. All of these factors contribute to increased risk of CVD (cardiovascular disease). Since little is known about postprandial dyslipidaemia in overweight children, we sought to c...

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...
