PCSK9 Promotes Intestinal Overproduction of Triglyceride-Rich Apolipoprotein-B Lipoproteins Through Both LDL-Receptor Dependent and Independent Mechanisms Running title: Rashid et al.; PCSK9 Promotes Intestinal ApoB Overproduction

Intestinal apolipoprotein synthesis and secretion in the suckling pig.

The present studies report characterization of intestinal apolipoprotein (apoLp) synthesis and secretion in the suckling pig. Lipoproteins (d less than 1.006 g/ml) from mesenteric lymph were found to contain both apoB-100 and B-48, in addition to apoA-IV, E, A-I, and Cs. Lymph low density lipoproteins (LDL) and high density lipoproteins (HDL) contained mainly apoB-100 and apoA-I, respectively. ...

Differential tissue-specific expression of human apoA-I and apoA-II.

To evaluate the sources of high density lipoprotein (HDL) particles containing only apolipoprotein A-I (apoA-I), the synthesis of apoA-I and apolipoprotein A-II (apoA-II) was examined in human liver and small intestine as well as the human intestinally derived cell line, Caco-2. Human liver contained apoA-I, apoA-II as well as apolipoprotein B (apoB) mRNA. In contrast, human adult small intesti...

Both apolipoproteins B-48 and B-100 are synthesized and secreted by the human intestine.

Apolipoprotein B (apoB), an apolipoprotein associated with very low density lipoproteins and the atherogenic low density lipoproteins (LDL), directs the metabolism of lipoprotein particles in plasma by interacting with the LDL receptor. Utilizing human intestinal biopsy organ cultures, we have studied the synthesis of intestinal apoB in man. Intestinal organ cultures from normal adults (n = 6) ...

Effect of Corn Oil, Olive Oil and Sheep’s and Cow’s Ghee on the Expression of apoB Protein in Syrian Mice’s Intestine and Liver

Background and Aims: Type and saturation of fatty acids can have an important impact on the level of triglyceride, cholesterol, very low and low-density lipoproteins in the blood and thus affect the development of atherosclerosis. Saturated fatty acids have an additive effect on blood cholesterol while for unsaturated fatty acids, a lowering effect has been reported. Fatty acids can have differ...
