HOW DO ApoB ANTISENSE OLIGONUCLEOTIDES WORK?

Lipid-lowering agents also known as cholesterol-lowering, hypolipidemic, or antihyperlipidemic agents are a group of drugs used to reduce high levels of lipids (fats) and lipoproteins (fats with protein) in the blood. These drugs are used to treat cardiovascular abnormalities such as atherosclerosis (build-up of fats and other substances in the wall of arteries, causing obstruction of blood flow) and decrease the risk of potential heart attacks. Lipid-lowering agents include:

  • Apolipoprotein B (ApoB) antisense oligonucleotides
  • Adenosine triphosphate citrate lyase inhibitors
  • 2-Azetidiones
  • Microsomal triglyceride transfer protein inhibitors
  • Statins (β-hydroxy β-methylglutaryl-CoA reductase inhibitor)
  • Fibrates
  • Bile acid sequestrants
  • Omega 3 acids
  • Vitamin B3

Apo B antisense oligonucleotides are a new class of drugs that reduce the production of ApoB-100 in the liver cells, which are principal lipoproteins of low-density lipoprotein (LDL, bad cholesterol) and essential for the synthesis of very-low-density lipoprotein (VLDL).

During the formation of lipoproteins, Apo B-100 genes present in the liver cells are converted from DNA into mRNA and the mRNA formed is further converted into ApoB-100. ApoB antisense oligonucleotides bind to the mRNA and prevent the formation of ApoB-100. Therefore, these drugs reduce the levels of LDL, non-high-density lipoprotein cholesterol, total cholesterol, and ApoB in the blood.

HOW ARE ApoB ANTISENSE OLIGONUCLEOTIDES USED?

ApoB antisense oligonucleotides are injectables, given subcutaneously, and used to treat conditions such as:
