Insights

The ErbB receptor tyrosine kinases (RTKs) are crucial for heart development and function. Understanding their role offers potential therapeutic targets for congenital heart defects and adult cardiomyopathies.

Area of Science:

  • Cardiovascular Biology
  • Molecular Signaling

Background:

  • The ErbB family of receptor tyrosine kinases (RTKs) mediates cellular communication crucial for tissue development and homeostasis.
  • These receptors play a vital role in cell differentiation, migration, and proliferation, processes essential for cardiac morphogenesis and function.

Purpose of the Study:

  • To review the critical roles of ErbB RTKs in heart development, including chamber formation and valve development.
  • To examine the function of ErbB signaling in maintaining adult heart health and preventing cardiomyopathies.
  • To explore therapeutic implications for congenital heart defects and adult cardiac diseases.

Main Methods:

  • Review of existing literature, including studies on transgenic mouse models.
  • Analysis of data from cancer therapeutics revealing ErbB signaling's role in adult cardiomyocytes.
  • Synthesis of information on ErbB RTK function in both embryonic development and adult cardiac physiology.

Main Results:

  • ErbB receptors are indispensable for proper heart morphogenesis, including the formation of a four-chambered heart and valve development.
  • Dysregulation or attenuation of ErbB signaling in adults can lead to cardiotoxicity and cardiomyopathies.
  • Transgenic mouse models highlight the significance of ErbB signaling in cardiac development and disease.

Conclusions:

  • ErbB RTKs are essential regulators of cardiac development and function throughout life.
  • Targeting ErbB signaling pathways presents a promising avenue for therapeutic interventions in congenital heart defects and adult cardiac diseases.
  • Further research into ErbB signaling networks can elucidate mechanisms underlying cardiac diseases and inform novel treatment strategies.

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal

Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.
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...
Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
Transducer Mechanism: Enzyme-Linked Receptors01:27

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:
Notch Signaling Pathway03:14

Notch Signaling Pathway

The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not until 1985...
Hedgehog Signaling Pathway02:33

Hedgehog Signaling Pathway

The Hedgehog gene (Hh) was first discovered due to its control of the growth of disorganized, hair-like bristles phenotype in Drosophila, much like hedgehog spines. Hh plays a crucial role in the development of organs and the maintenance of homeostasis in both invertebrates and vertebrates. However, while Drosophila has only one Hh protein, mammals have multiple functional Hedgehog proteins - Sonic (Shh), Desert (Dhh), and Indian Hedgehog (Ihh). All of these homologous proteins have adapted to...
