Insights

Vascular smooth muscle cell (VSMC) proliferation drives vascular diseases. This review highlights how insulin and thrombin signaling, particularly the ERK1/2 pathway, mediate VSMC hypertrophy and offers therapeutic targets for atherosclerosis and hypertension.

Area of Science:

  • Biochemistry
  • Cell Biology
  • Cardiovascular Research

Background:

  • Vascular smooth muscle cell (VSMC) proliferation is central to vascular diseases like atherosclerosis and hypertension.
  • Extracellular signal-regulated kinases (ERKs), specifically ERK1/2, are known to be involved in VSMC mitogenesis.
  • Intracellular signaling pathways regulating VSMC proliferation remain incompletely understood.

Purpose of the Study:

  • To review recent findings on insulin (INS) and thrombin (Thr) signaling mechanisms.
  • To emphasize the role of the ERK1/2 signaling pathway in VSMC proliferation and hypertrophy.
  • To identify ERK1/2 as a potential therapeutic target for vascular diseases.

Main Methods:

  • Literature review of recent studies on VSMC signaling.
  • Focus on intracellular pathways activated by INS and Thr.
  • Analysis of the ERK1/2 pathway's role in VSMC hypertrophy.

Main Results:

  • INS and Thr activate signaling cascades that promote VSMC proliferation.
  • The ERK1/2 pathway is a key mediator of INS- and Thr-induced VSMC hypertrophy.
  • Understanding these pathways is crucial for developing new treatments.

Conclusions:

  • The ERK1/2 pathway is a critical mediator of VSMC hypertrophy.
  • Targeting the ERK1/2 pathway presents a promising therapeutic strategy for hypertension and atherosclerosis.
  • Further research into INS and Thr signaling can lead to novel interventions for vascular disease.

PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a rapamycin-insensitive companion...
Intracellular Signaling Affects Focal Adhesions01:17

Intracellular Signaling Affects Focal Adhesions

Integrins act both as extracellular input receivers and as intracellular processing activators. As their name suggests, integrins are entirely integrated into the membrane structure. Their hydrophobic membrane-spanning regions interact with the phospholipid bilayer's hydrophobic region. These membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors. They activate intracellular response cascades when their effectors are bound and active.

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...
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...
cAMP-dependent Protein Kinase Pathways01:25

cAMP-dependent Protein Kinase Pathways

Cyclic Adenosine Monophosphate (cAMP) is an essential second messenger that activates protein kinase A (PKA) and regulates various biological processes. A single epinephrine molecule binds to GPCR and activates several heterotrimeric G proteins, each stimulating multiple adenylyl cyclase, amplifying the signal, and synthesizing large numbers of cAMP molecules. Small changes in cAMP concentration affect PKA activity. The binding of four cAMP molecules induces a conformational change in PKA,...
TGF - β Signaling Pathway01:16

TGF - β Signaling Pathway

The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors are of three kinds RI, RII, and RIII. The RI...
