Insights

Eph receptors and ephrin ligands, crucial for development, are implicated in various human cancers. Their aberrant expression drives tumorigenesis, making them potential therapeutic targets.

Area of Science:

  • Molecular Biology
  • Cell Biology
  • Oncology

Background:

  • Eph receptors form the largest receptor tyrosine kinase family, activated by membrane-anchored or transmembrane ephrin ligands.
  • These receptor-ligand pairs are vital in multicellular organism development, including axon guidance, vascular patterning, and tissue injury inflammation.
  • Aberrant Eph/ephrin signaling is linked to altered proliferation, migration, and invasion in human cancers, positioning them as therapeutic targets.

Purpose of the Study:

  • To investigate the role of Eph receptors and ephrin ligands in specific human carcinomas and brain tumors.
  • To describe the involvement of Eph/ephrin signaling in tumorigenesis across multiple cancer types.
  • To explore the link between Eph/ephrin dysregulation and cancer development.

Main Methods:

  • Review and synthesis of existing literature on Eph receptors and ephrin ligands in cancer.
  • Analysis of Eph/ephrin expression patterns in lung, breast, prostate, and colorectal carcinomas, glioblastoma, and medulloblastoma.
  • Examination of signaling pathways associated with Eph/ephrin dysregulation in tumorigenesis.

Main Results:

  • Eph receptors and ephrin ligands are involved in lung, breast, prostate, and colorectal carcinomas, as well as glioblastoma and medulloblastoma.
  • Aberrations in the abundance of these molecules are observed across these diverse cancer types.
  • Differential expression of Eph/ephrin signaling components is implicated as a mechanism driving cancer development.

Conclusions:

  • Eph receptors and ephrin ligands play a significant role in the pathogenesis of various human cancers.
  • Dysregulation of Eph/ephrin signaling pathways contributes to cancer progression.
  • Targeting Eph/ephrin interactions presents a promising strategy for novel cancer therapeutics.

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.

Ligand Binding and Linkage00:49

Ligand Binding and Linkage

Allosteric proteins have more than one ligand binding site; the binding of a ligand to any of these sites influences the binding of ligands to the other sites. When a protein is allosteric, its binding sites are called coupled or linked.  In the case of enzymes, the site that binds to the substrate is known as the active site and the other site is known as the regulatory site. When a ligand binds to the regulatory site, this leads to conformational changes in the protein that can influence...

Internal Receptors01:31

Internal Receptors

Many cellular signals are hydrophilic and therefore cannot pass through the plasma membrane. However, small or hydrophobic signaling molecules can cross the hydrophobic core of the plasma membrane and bind to internal, or intracellular, receptors that reside within the cell. Many mammalian steroid hormones use this mechanism of cell signaling, as does nitric oxide (NO) gas.

Ligand-Gated Ion Channel Receptor: Gating Mechanism

Ligand-gated ion channels are transmembrane proteins that play a vital role in intercellular communication and functions of the nervous system. They allow the influx of ions across the membrane once the neurotransmitter binds, allowing the subsequent transmission of electrical excitation across the neurons. Other ligand-gated ion channels, like the γ-aminobutyric acid (GABA) receptor, permit anions like chloride into the cells on the binding of the GABA molecule. Their entry into the cell...

Ligand Binding Sites02:40

Ligand Binding Sites

Proteins are dynamic macromolecules that carry out a wide variety of essential processes; however, the activities of most proteins depend on their interactions with other molecules or ions, known as ligands.
Protein-ligand interactions are quite specific; even though numerous potential ligands surround a cellular protein at any given time, only a particular ligand can bind to that protein. Moreover, a ligand binds only to a dedicated area on the surface of the protein, known as the...

Metal-Ligand Bonds02:51

Metal-Ligand Bonds

The hemoglobin in the blood, the chlorophyll in green plants, vitamin B-12, and the catalyst used in the manufacture of polyethylene all contain coordination compounds. Ions of the metals, especially the transition metals, are likely to form complexes.
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
