Insights

Statins reduce vascular inflammation by inhibiting nuclear factor kappaB (NF-kappaB) signaling in endothelial cells. This effect is mediated through the PI3-kinase/Akt pathway, not the classical IKK pathway.

Area of Science:

  • Cardiovascular Biology
  • Molecular Medicine
  • Cellular Signaling

Background:

  • Statins offer vascular benefits, potentially by reducing chronic inflammation.
  • Nuclear factor kappaB (NF-kappaB) is crucial for inflammatory gene transcription.
  • Understanding statin's impact on NF-kappaB signaling in endothelial cells is key.

Purpose of the Study:

  • To investigate how statins affect tumor necrosis factor-alpha (TNF-alpha)-induced NF-kappaB signaling in human endothelial cells (ECs).
  • To elucidate the specific molecular pathways involved in statin-mediated inhibition of NF-kappaB activation.

Main Methods:

  • Human endothelial cells (ECs) were treated with cerivastatin and stimulated with TNF-alpha.
  • NF-kappaB binding activity, p65 nuclear translocation, and tissue factor (TF) gene transcription were assessed.
  • Phosphatidylinositol 3-kinase (PI3K)/Akt pathway activation and IkappaBalpha phosphorylation/degradation were analyzed.

Main Results:

  • Statin treatment inhibited TNF-alpha-induced NF-kappaB binding, p65 nuclear translocation, and TF gene transcription.
  • Statin treatment abrogated TNF-alpha-induced Akt phosphorylation and p65 nuclear translocation.
  • Inhibition of PI3K blocked p65 translocation but not IkappaBalpha phosphorylation or degradation.

Conclusions:

  • Statin treatment abrogates TNF-alpha-induced NF-kappaB activation in endothelial cells.
  • This inhibition occurs via the PI3-kinase/Akt pathway, independent of the classical IKK pathway.
  • Statins represent a potential therapeutic strategy for managing vascular inflammation.

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...
Non-Canonical Wnt Signaling Pathways01:41

Non-Canonical Wnt Signaling Pathways

Wnt is a zygotic effect gene that is expressed during very early embryonic development. It regulates various processes in animals starting from early development through the adult stage, such as organogenesis in the embryo and maintenance of neuronal and blood stem cells. Wnt proteins can induce a wide variety of intracellular pathways depending upon the specific abilities of different Wnt ligands to form a complex with shared and cognate receptors in the presence of different co-receptors. The...
The Intrinsic Apoptotic Pathway01:31

The Intrinsic Apoptotic Pathway

Internal cellular stress, such as cellular injury or hypoxia, triggers intrinsic apoptosis. The B-cell lymphoma 2 (Bcl-2) family of proteins are the primary regulators of the intrinsic apoptotic pathway. For example, during DNA damage, checkpoint proteins, such as Ataxia Telangiectasia Mutated (ATM protein) and Checkpoints Factor-2 (Chk2) proteins, are activated. These proteins phosphorylate p53 which further activates pro-apoptotic proteins, such as Bax, Bak, PUMA, and Noxa, and inhibits...
Phosphoinositides and PIPs01:42

Phosphoinositides and PIPs

Phosphoinositides are a group of phospholipids containing a glycerol backbone with two fatty acid chains and a phosphate attached to a myoinositol sugar ring. The inositol head group extends into the cytoplasm, where it is modified by adding phosphate groups to form phosphatidylinositol phosphates or PIPs.
Different phosphoinositides are synthesized and recruited on the cytosolic face of the plasma membrane. The localization of specific phosphoinositides concentrated in separate membrane...
Inhibitors of Viral Protein Synthesis01:30

Inhibitors of Viral Protein Synthesis

Protein synthesis is indispensable for viral replication, as viruses lack the cellular machinery required for this process and must hijack the host's translational apparatus. In response, host cells deploy a critical innate immune defense involving interferons, specialized cytokines that play a central role in inhibiting viral propagation.Upon viral detection, infected cells release interferons that bind to receptors on adjacent uninfected cells, activating the JAK-STAT signaling pathway and...
