Insights

Eph receptors and ephrin ligands are key to cell communication and tissue development. Their re-emergence in cancer offers potential anticancer therapy targets, but requires deeper understanding of their tumor progression roles.

Area of Science:

  • Cellular and Molecular Biology
  • Developmental Biology
  • Oncology

Background:

  • Eph receptors and ephrin ligands form a prevalent cell-cell communication system.
  • This system is crucial for guiding cell positioning and tissue patterning in multicellular organisms.
  • Their functions in embryonic development are often reactivated during oncogenesis.

Purpose of the Study:

  • To explore the role of Eph receptors and ephrin ligands in oncogenesis.
  • To evaluate their potential as targets for anticancer therapies.
  • To understand the complex activities of Eph receptors during tumor progression.

Main Methods:

  • Review of extensive research over the past 15 years.
  • Analysis of preclinical and early clinical development data.
  • Examination of the expression patterns of Eph and ephrin family members in cancer.

Main Results:

  • Eph/ephrin signaling is implicated in coordinating cell adhesion and segregation.
  • Re-emerged embryonic patterning functions of Eph/ephrin are observed in cancer.
  • First-generation therapies (antibodies, inhibitors, vaccines) show preclinical promise.

Conclusions:

  • Eph receptors and ephrin ligands are critical regulators of cell communication and tissue development.
  • Their reactivation in cancer presents promising therapeutic opportunities.
  • Comprehensive understanding of Eph receptor activity in tumors is essential for successful clinical application.

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...
Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against specific...

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal01:22

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.
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:
Combination Therapies and Personalized Medicine02:50

Combination Therapies and Personalized Medicine

Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
