Hepatic apo-A-I and apo-E and intestinal apo-A-I are synthesized in precursor isoprotein forms by organ cultures of human fetal tissues.

In this report, we demonstrate that organ cultures of human fetal liver and intestine synthesize and secrete into the culture medium the major apolipoproteins. The liver cultures were shown to produce apo-A-I, apo-A11, apo-B, apo-C-11, apo-C-IIIs, and apo-E, and the cultures of intestine produced primarily apo-A-I. The synthesized apolipoproteins secreted into the culture medium were identified...

Apo A-i and Apo E Interaction: beyond Lipoproteins

Apolipoproteins (Apo) A-I, A-II, A-IV, and E possess repeated amphipathic helical regions with the same genomic structure and are members of a multigene family that probably evolved from a common ancestral gene [1]. These apolipoproteins play pivotal roles in lipid transport and lipoprotein metabolism, and their carboxyl-terminal domain is critical for lipid binding [2]. The purpose of this com...

Apo B/apo A-I ratio and cardiovascular risk prediction.

Apolipoproteins are proteins associated with lipids in lipoprotein particles. They play important roles in lipoprotein metabolism, such as transport of these hydrophobic molecules in plasma aqueous medium, binding to specific receptors in cell surface to correctly direct lipids to target organs and body tissues, and activation or inhibition of enzymes involved in lipid metabolism. Apolipoprotei...

Distribution of ' 25 I - Apo B and ' 25 I - Apo Cin Control and Lipolyzed VLDL 125 I - Apo B

Endogenous apolipoprotein E in VLDL is poorly expressed in receptor binding processes. Yet catabolism ofVLDL-remnants by cellular receptors depends on functional apo E molecules. To better understand remnant catabolism phenomena, we determined the metabolism of VLDL and post-lipolysis VLDL by cultured cells. Partial lipolysis was achieved by incubation of VLDL with lipoprotein lipase in vitro (...

Effect of Chronic Hypo - and Hyperthyroidism on Apo A - I , Apo E , and Albumin mRNAAbundance and Apo A - I Gene Transcription in Rat Liver

To study the regulation of hepatic apo A-I gene expression, we measured synthesis and abundance of cellular apo A-I mRNA and its nuclear precursors in livers of hypothyroid and hyperthyroid rats. In hypothyroid animals, both synthesis and abundance of apo A-I mRNA was reduced to half of control values. After injection of a receptor-saturating dose of triiodothyronine into euthyroid rats, apo A-...
