Insights

Atherosclerosis shares inflammatory pathways with diseases like rheumatoid arthritis, particularly involving nuclear factor kappaB (NFkappaB) activation. Understanding NFkappaB

Area of Science:

  • Cardiovascular science
  • Immunology
  • Molecular biology

Background:

  • Cardiovascular diseases are a major cause of death in Western countries.
  • Atherosclerosis, a key contributor to cardiovascular disease, involves lipid and fibrotic buildup in arteries.
  • Atherosclerosis shares characteristics with chronic inflammatory diseases, including leukocyte infiltration and cytokine production.

Purpose of the Study:

  • To investigate the role of the nuclear factor kappaB (NFkappaB) signaling pathway in atherosclerosis.
  • To identify potential therapeutic targets within the NFkappaB cascade for cardiovascular disease treatment.

Main Methods:

  • Review of existing literature on atherosclerosis and inflammatory signaling pathways.
  • Analysis of shared molecular mechanisms between atherosclerosis and inflammatory diseases.
  • Focus on the activation and regulation of NFkappaB in atherosclerotic plaques.

Main Results:

  • Atherosclerosis exhibits significant overlap with chronic inflammatory conditions.
  • Shared signaling pathways, notably NFkappaB activation, are implicated in both.
  • NFkappaB activation is influenced by various stimuli in atherosclerosis and regulates key inflammatory genes.

Conclusions:

  • The nuclear factor kappaB (NFkappaB) cascade plays a critical role in atherosclerosis pathogenesis.
  • Targeting the NFkappaB pathway offers potential for novel therapeutic strategies.
  • Further research into NFkappaB in atherosclerosis is essential for developing effective treatments.

NF-κB-dependent Signaling Pathway

The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

Regulation of Nuclear Protein Sorting01:45

Regulation of Nuclear Protein Sorting

Nuclear protein sorting regulates nucleus composition and gene expression, crucial for determining the fate of a eukaryotic cell. Hence, the entry and exit of molecules across the nuclear envelope is a tightly controlled process. Nuclear protein sorting can be inhibited by one of the following ways: 1) masking cargo signal sequences, 2) modifying the nuclear receptor's affinity for cargo, 3) controlling the nuclear pore size, 4) retaining the cargo during its transit to the cytosol or the...
Transducer Mechanism: Nuclear Receptors01:31

Transducer Mechanism: Nuclear Receptors

Nuclear receptors, or NRs, are unique transcription factors that regulate gene transcription and affect the cellular pathways involved in reproduction, development, or metabolism. Their ability to be stimulated by small lipophilic ligands and control vital cellular processes makes them ideal drug targets. Nearly 10-15% of currently prescribed drugs target these receptors.
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:

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...
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...
