AI Article Synopsis

  • Erythropoietin-producing hepatoma (Eph) receptors are a major family of receptor tyrosine kinases that influence key biological processes and are involved in cancer progression.
  • These receptors interact with ephrins to regulate essential functions like embryo development, tissue formation, and tumor cell survival.
  • Recent studies have shown their significant role in cardiovascular health, affecting conditions such as atherosclerosis and cardiac fibrosis, highlighting their potential for new treatments in heart-related diseases.

Article Abstract

Erythropoietin-producing hepatoma (Eph) receptors, comprising the largest family of receptor tyrosine kinases (RTKs), exert profound influence on diverse biological processes and pathological conditions such as cancer. Interacting with their corresponding ligands, erythropoietin-producing hepatoma receptor interacting proteins (Ephrins), Eph receptors regulate crucial events like embryonic development, tissue boundary formation, and tumor cell survival. In addition to their well-established roles in embryonic development and cancers, emerging evidence highlights the pivotal contribution of the Ephrin/Eph family to cardiovascular physiology and pathology. Studies have elucidated their involvement in cardiovascular development, atherosclerosis, postnatal angiogenesis, and, more recently, cardiac fibrosis and calcification, suggesting a promising avenue for therapeutic interventions in cardiovascular diseases. There remains a need for a comprehensive synthesis of their collective impact in the cardiovascular context. By exploring the intricate interactions between Eph receptors, ephrins, and cardiovascular system, this review aims to provide a holistic understanding of their roles and therapeutic potential in cardiovascular health and diseases.

Inhibition of EphA2 by syndecan-4 in wounded skin regulates clustering of fibroblasts.

J Mol Cell Biol

Upon injury, fibroblasts in the surrounding tissue become activated, migrating into the wound in a controlled manner. Once they arrive, they contract the wound and remodel the stroma. While certain cell surface receptors promote fibroblast migration, others cause repulsion between fibroblasts upon contact, seemingly opposing their clustering within the wound bed.

EFNA4, a member of the Ephrin-A ligand family, may influence hepatocellular carcinoma cells through two distinct mechanisms: one reliant on specific Eph receptor binding and the other independent of receptor involvement. However, EFNA4's influence on HCC via non-Eph receptor pathways remains unclear. In this study, we aimed to investigate the role of EFNA4 in a receptor-independent environment.

Constrained β-Hairpins Targeting the EphA4 Ligand Binding Domain.

J Med Chem

The activity of the receptor tyrosine kinase EphA4 has been implicated in several pathologies including oncology (gastric and pancreatic cancers) and neurodegenerative diseases (amyotrophic lateral sclerosis and Alzheimer's disease). However, advances in validating EphA4 as a possible drug target have been limited by the lack of suitable pharmacological inhibitors. Recently, we reported on the design of potent EphA4 agonistic agents targeting its ligand binding domain (LBD).

Article Synopsis
  • Hidden biases in non-randomized studies challenge the identification of causal protein biomarkers for Alzheimer's disease, and traditional methods can lead to misleading results.
  • The MR-SPI method enhances Mendelian randomization by selecting valid pQTL instruments, addressing some of these biases and integrating structural predictions from AlphaFold3.
  • Using data from over 500,000 individuals, researchers identified seven proteins with structural changes linked to Alzheimer's, contributing to understanding the disease's causes and potential treatment targets.

Receptor tyrosine kinases (RTKs) regulate many cellular functions and are important targets in pharmaceutical development, particularly in cancer treatment. EGFR and EphA2 are two key RTKs that are associated with oncogenic phenotypes. Several studies have reported functional interplay between these receptors, but the mechanism of interaction is still unresolved.
