Protein heterogeneity of lipoprotein particles containing apolipoprotein A-I without apolipoprotein A-II and apolipoprotein A-I with apolipoprotein A-II isolated from human plasma.

The Effect of Training Type on Hepatic Gene expressions of Apolipoprotein A‐I, and Apolipoprotein A‐II among Male Wistar Rats

Introdaction: Lipid metabolism disorders, especially raised levels of cholesterol and triglycerides increases the risk of atherosclerosis. This study aimed to investigate the effect of training type including submaximal continuous and high-intensity interval training on hepatic gene expression of Apolipoprotein A‐I, and Apolipoprotein A‐II in male Wistar rats.   Materials & Methods: This exper...

Influence of apolipoprotein A-I and apolipoprotein A-II availability on nascent HDL heterogeneity.

It is important to understand HDL heterogeneity because various subspecies possess different functionalities. To understand the origins of HDL heterogeneity arising from the existence of particles containing only apoA-I (LpA-I) and particles containing both apoA-I and apoA-II (LpA-I+A-II), we compared the abilities of both proteins to promote ABCA1-mediated efflux of cholesterol from HepG2 cell...

Apolipoprotein complexity in Japanese eel Anguilla japonica: truncated apolipoprotein A-I and apolipoprotein A-I-like protein in plasma lipoproteins.

A truncated apolipoprotein (apo) A-I with a molecular weight (M(r)) of 26 kDa was first isolated from the plasma high density lipoproteins of an atypical Japanese eel (Anguilla japonica). Interestingly, this eel contained a very small amount of intact apoA-I (M(r)28 kDa) in the plasma, although serine protease inhibitors were present throughout the plasma preparation. The N-terminal sequence of...

Interactions of Apolipoprotein A-I with High-Density Lipoprotein Particles

Although the partitioning of apolipoprotein A-I (apoA-I) molecules in plasma between high-density lipoprotein (HDL)-bound and -unbound states is an integral part of HDL metabolism, the factors that control binding of apoA-I to HDL particles are poorly understood. To address this gap in knowledge, we investigated how the properties of the apoA-I tertiary structure domains and surface characteris...
