Insights

Hepatocyte growth factor (HGF) protects the heart from ischemia-reperfusion injury by activating the PI3K-Akt pathway. This growth factor shows potential as a cardioprotective agent for various heart conditions.

Area of Science:

  • Cardiology
  • Molecular Biology
  • Cell Biology

Background:

  • Cardiomyocytes are vulnerable to ischemia-reperfusion injury.
  • Growth factors can protect cardiomyocytes via cell-surface receptors and intracellular signaling.
  • Hepatocyte growth factor (HGF) is a key growth factor involved in cardiac repair.

Purpose of the Study:

  • To review the cardioprotective role of HGF in ischemia-reperfusion injury.
  • To focus on the signaling pathways underlying HGF's protective effects.
  • To highlight HGF's potential as a therapeutic agent for cardiac conditions.

Main Methods:

  • Review of existing literature on HGF and myocardial protection.
  • Analysis of HGF's role in activating the PI3K-Akt signaling pathway.
  • Examination of HGF's effects on angiogenesis, apoptosis, and cell regeneration.

Main Results:

  • HGF activates the phosphatidylinositol 3-kinase (PI3K)-Akt pathway, conferring cardioprotection during myocardial infarction and reperfusion.
  • HGF exhibits mitogenic, angiogenic, antiapoptotic, and antifibrotic activities in cardiac cells.
  • Endogenous HGF promotes angiogenesis and inhibits apoptosis, aiding in ischemic myocardium regeneration.

Conclusions:

  • HGF plays a significant role in protecting cardiomyocytes from ischemia-reperfusion injury.
  • The PI3K-Akt pathway is a crucial mediator of HGF-induced cardioprotection.
  • HGF holds promise as a therapeutic agent for treating pathological cardiac conditions.

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,...
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...

Transducer Mechanism: Enzyme-Linked Receptors

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:

Treatment for Pulmonary Arterial Hypertension: Receptor Tyrosine Kinase Inhibitors and Calcium Channel Blockers

Receptor tyrosine kinase inhibitors (TKIs) and calcium channel blockers (CCBs) are two critical categories of drugs employed in the treatment of pulmonary artery hypertension (PAH). PAH is a disease that causes high blood pressure in the pulmonary arteries, resulting in chest pain, fatigue, and shortness of breath.
TKIs, such as imatinib (Gleevec), are particularly effective in tackling the growth and mitogenic factors that become upregulated in PAH patients. These factors contribute to the...
