Abstract

Insights

Targeting the angiopoietin-like protein (ANGPTL) 3-4-8 axis offers a novel approach to lipid metabolism and cardiovascular risk reduction. ANGPTL3 inhibition shows significant promise for managing dyslipidemia, particularly in familial hypercholesterolemia.

Area of Science:

  • Cardiovascular Medicine
  • Metabolic Disorders
  • Pharmacology

Background:

  • The angiopoietin-like protein (ANGPTL) 3-4-8 axis is a key regulator of lipoprotein lipase and lipid metabolism.
  • Dyslipidemia contributes significantly to cardiovascular disease risk.

Purpose of the Study:

  • To review the mechanistic basis of ANGPTL pathway modulation.
  • To explore therapeutic implications for cardiovascular risk reduction in dyslipidemia.

Main Methods:

  • Review of genetic studies and clinical trials involving ANGPTL pathway modulation.
  • Examination of pharmacologic inhibition strategies (monoclonal antibodies, RNA-based therapies).

Main Results:

  • Loss-of-function variants in ANGPTL3/4 correlate with lower triglycerides and reduced coronary artery disease risk.
  • ANGPTL3 inhibition effectively reduces triglycerides, remnant cholesterol, LDL-C, and apoB, largely independent of the LDL receptor.
  • ANGPTL3 inhibitors have shown significant LDL-C reductions in homozygous familial hypercholesterolemia and mixed dyslipidemia.

Conclusions:

  • Modulating the ANGPTL-lipoprotein lipase axis is a novel strategy for addressing residual atherosclerotic risk.
  • ANGPTL-directed therapies offer promising cardiovascular risk mitigation for patients with dyslipidemia, including those with HoFH.

Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...

Atherosclerosis III: Management

Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...
Atherosclerosis I: Introduction01:30

Atherosclerosis I: Introduction

Atherosclerosis is a progressive disorder characterized by the buildup of plaques on the arterial inner wall, causing them to narrow and harden over time. These plaques comprise lipids, calcium, blood components, carbohydrates, and fibrous tissue. The process primarily affects the intima of large and medium-sized arteries, reducing blood flow in any artery.Etiology and risk factorsThe cause of atherosclerosis is multifactorial, involving a complex interplay among endothelial injury, lipid...

Coronary Artery Disease I: Introduction

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...
Mechanism of Angiogenesis01:10

Mechanism of Angiogenesis

Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...

Pharmacogenomics: Identification of New Drug Targets

Advances in genomics have profoundly influenced drug discovery by increasing both the speed and accuracy of pharmaceutical development. Pharmacogenomics, which examines how genetic variation influences drug response, facilitates the identification of novel therapeutic targets and enables patient stratification for personalized treatment. These strategies contribute to improved drug efficacy, minimized adverse effects, and more efficient clinical trial design.Mapping genetic differences...
