Application


  • The common p.Ile291Val variant of ERLIN1 enhances TM6SF2 function and is associated with protection against MASLD.: This study investigates a variant of ERLIN1 and its role in enhancing TM6SF2 function, highlighting how Apolipoprotein B from human plasma contributes to understanding metabolic-associated liver disease (MASLD) protection (Rendel et al., 2024).

  • Blood Lipids, Lipoproteins, and Apolipoproteins With Risk of Coronary Heart Disease: A Prospective Study Among Racially Diverse Populations.: This prospective study evaluates the relationship between blood lipids, lipoproteins, Apolipoprotein B, and the risk of coronary heart disease across diverse populations, providing crucial insights into cardiovascular risk assessment (Deng et al., 2024).

  • The genomic landscape of Vk*MYC myeloma highlights shared pathways of transformation between mice and humans.: Research in this paper identifies shared pathways in myeloma transformation between mice and humans, utilizing Apolipoprotein B from human plasma to understand the molecular mechanisms involved in this process (Maura et al., 2024).


Biochem/physiol Actions

Apo-B levels correlate with the risk of coronary disease. Apo-B exists in human plasma in two isoforms, Apo-B48 and Apo-B100. Apo-B100 is the major physiological ligand for the LDL receptor. Apo-B100 is a large monomeric protein, containing 4563 amino acids (MW 515 kDa). Apo-B100 is synthesized in the liver and is required for the assembly of VLDL. It does not interchange between lipoprotein particles, as do the other apolipoproteins, and it is found in IDL and LDL after the removal of the Apo-A, E, and C. Apo-B48 is present in chylomicrons and their remnants. It is essential for the intestinal absorption of dietary lipids.
Apo-B48 is synthesized in the small intestine. It comprises approximately half of the N-terminal region of Apo-B100 and is the result of posttranscriptional mRNA editing by a stop codon in the intestine not found in the liver. The concentration of Apo-B in normal plasma is ~90 mg/dl.

Since cholesterol is a water-insoluble molecule it must be packaged for transport within the plasma. The particles that package cholesterol, cholesteryl esters, and triglycerides for transport, are called lipoproteins.
