Insights

Thalidomide may disrupt embryonic development by interfering with N-cadherin, an adhesion molecule crucial for cell interactions. This study used computational docking to show thalidomide binding to N-cadherin, suggesting a mechanism for developmental toxicity.

Area of Science:

  • Developmental biology
  • Molecular pharmacology
  • Biochemistry

Background:

  • N-cadherin is an adhesion molecule involved in embryogenesis.
  • Embryonic development stages sensitive to thalidomide overlap with N-cadherin functions.

Purpose of the Study:

  • To investigate the hypothesis that thalidomide interferes with N-cadherin-mediated cell interactions.
  • To elucidate the molecular mechanism underlying thalidomide's potential effects on N-cadherin.

Main Methods:

  • Protein-ligand docking simulations were employed.
  • The binding of thalidomide to N-cadherin was characterized computationally.

Main Results:

  • Thalidomide was found to bind to the N-terminal domain of N-cadherin.
  • The binding site mimics a tryptophan residue essential for N-cadherin homodimerization.

Conclusions:

  • Thalidomide may disrupt N-cadherin-mediated cell recognition and migration during morphogenesis.
  • This interaction provides a potential molecular explanation for thalidomide's teratogenic effects.

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...
Intracellular Signaling Affects Focal Adhesions01:17

Intracellular Signaling Affects Focal Adhesions

Integrins act both as extracellular input receivers and as intracellular processing activators. As their name suggests, integrins are entirely integrated into the membrane structure. Their hydrophobic membrane-spanning regions interact with the phospholipid bilayer's hydrophobic region. These membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors. They activate intracellular response cascades when their effectors are bound and active.

Structure of Cadherins01:25

Structure of Cadherins

The cadherins were one of the first cell adhesion molecules discovered; the term “cadherins”   is based on their calcium-dependent adhering properties. The first cadherins discovered on the epithelial, neuronal, and placental cells were named E-cadherin, P-cadherin, and N-cadherin, respectively. These classical cadherins share sequence and structural similarities. Other cadherins, including those involved in cell signaling, are grouped into non-classical cadherins. This diversity of cadherins...
Catenins01:23

Catenins

Catenins are characterized by multiple binding domains and dynamic structures that allow them to function as linker proteins in cell junction complexes. All catenins, except α-catenin, contain a characteristic protein sequence called the armadillo repeat and are therefore also called armadillo proteins.
Catenins in Cell Junctions
Catenins bind to cell adhesion molecules such as cadherins and link them to different cytoskeletal proteins depending on the type of cell junction. At the adherens...
Cadherins in Tissue Organization01:19

Cadherins in Tissue Organization

The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of cadherin types. Cadherins generally exhibit homophilic binding; i.e., cadherins on one cell bind to cadherins of the same or closely related type on another cell. Thus, cells of the same type have a specific affinity to bind to each other and sort themselves into clusters to form tissues.

Teratogenicity01:07

Teratogenicity

The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
