Insights

Nuclear factor kappa B (NFkappaB) plays a key role in heart disease. This review explores NFkappaB's function in ischemia-reperfusion injury, preconditioning, and chronic heart failure.

Area of Science:

  • Cardiovascular Science
  • Immunology
  • Molecular Biology

Background:

  • Ischemic heart disease is a leading cause of death, often leading to chronic heart failure.
  • Ischemia-reperfusion injury can cause heart cell death through necrosis or apoptosis.
  • Myocardial adaptation to ischemia can be achieved through preconditioning, involving brief episodes of ischemia and reperfusion.

Purpose of the Study:

  • To review the fundamental regulation of Nuclear Factor kappa B (NFkappaB).
  • To explore the role of NFkappaB activation in ischemia-reperfusion injury.
  • To examine NFkappaB's involvement in myocardial adaptation and chronic heart failure.

Main Methods:

  • Literature review of basic NFkappaB regulation.
  • Analysis of NFkappaB's role in cardiovascular pathology.
  • Synthesis of current research on NFkappaB in heart conditions.

Main Results:

  • NFkappaB is a crucial redox-sensitive transcription factor regulating innate and adaptive immunity.
  • NFkappaB activation influences inflammatory gene expression, including adhesion molecules and cytokines like tumor necrosis factor alpha.
  • NFkappaB may also contribute to tissue remodeling and the resolution of inflammation.

Conclusions:

  • NFkappaB activation is implicated in the pathogenesis of ischemia-reperfusion injury and chronic heart failure.
  • Understanding NFkappaB's dual role in inflammation and resolution is critical for therapeutic strategies.
  • Targeting NFkappaB pathways may offer novel approaches for myocardial protection and treatment of heart failure.

NF-κB-dependent Signaling Pathway02:26

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.

The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as  SH2...

Co-activators and Co-repressors

Gene transcription is regulated by the synergistic action of several proteins that form a complex at a gene regulatory site. This is observed in eukaryotes, where the regulation of gene expression is a complex process. Regulatory proteins in eukaryotes can broadly be classified into two types – regulators that bind directly to specific DNA sequences and co-regulators that associate with regulatory proteins but cannot directly bind to the DNA. These co-regulators are further divided into...
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:
MAPK Signaling Cascades01:07

MAPK Signaling Cascades

Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...
