Abstract

Insights

Hydroxyethyl starch 130/0.4 (voluven) reduces inflammatory markers in acute lung injury (ALI) by inhibiting p-P38 and AP-1 activation. This suggests a protective mechanism against infection-induced ALI.

Area of Science:

  • Molecular Biology
  • Cell Signaling
  • Pathophysiology

Context:

  • Acute lung injury (ALI) is a severe condition often triggered by infection.
  • The p38 mitogen-activated protein kinase (MAPK) pathway plays a critical role in inflammatory responses.
  • Understanding the molecular mechanisms underlying ALI is crucial for developing effective treatments.

Purpose:

  • To investigate the effect of hydroxyethyl starch 130/0.4 (voluven) on the p38 MAPK signaling pathway.
  • To elucidate the mechanism by which voluven may protect against infection-induced ALI.

Summary:

  • Lipopolysaccharide (LPS) administration in rats significantly increased the expression of phosphorylated p38 (p-P38), phosphorylated p44/42 (p-P44/42), and activating protein-1 (AP-1) activation.
  • Treatment with hydroxyethyl starch 130/0.4 (voluven) significantly reduced the expression of p-P38 and AP-1 activation in LPS-induced ALI.
  • No significant difference in efficacy was observed between voluven doses of 15 ml/kg and 30 ml/kg.

Impact:

  • Hydroxyethyl starch 130/0.4 demonstrates potential as a therapeutic agent for ALI.
  • The study highlights the role of the p38 MAPK pathway and AP-1 activation in LPS-induced ALI.
  • Findings provide insights into the anti-inflammatory mechanisms of hydroxyethyl starch in lung injury.

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...
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...
Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

Amplifying Signals via Enzymatic Cascade

When a ligand binds to a cell-surface receptor, the receptor's intracellular domain changes shape, which may either activate its enzyme function or allow its binding to other molecules. The initial signal is amplified by most signal transduction pathways. This means that a single ligand molecule can activate multiple molecules of a downstream target. Proteins that relay a signal are most commonly phosphorylated at one or more sites, activating or inactivating the protein. Kinases catalyze the...
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...
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,...
