Summary
Liver cell adhesion molecule N-CAM is active during Xenopus laevis metamorphosis. Its expression changes with cell interactions, but Thyroxine does not directly control this activation.
Area of Science:
- Developmental Biology
- Cell Biology
- Molecular Biology
Background:
- Cell-to-cell adhesion molecules play critical roles in tissue development and morphogenesis.
- Neural cell adhesion molecule (N-CAM) is involved in cell interactions.
- Understanding the function of N-CAM during amphibian metamorphosis is crucial for developmental studies.
Purpose of the Study:
- To investigate the functional activity and expression patterns of liver N-CAM during Xenopus laevis metamorphosis.
- To determine the correlation between liver N-CAM expression and morphological changes in cell-to-cell interactions.
- To examine the potential role of Thyroxine in regulating liver N-CAM expression during metamorphosis.
Main Methods:
- Analysis of liver N-CAM expression during Xenopus laevis metamorphosis.
- Assessment of cell-to-cell interactions and morphological changes.
- Investigation of Thyroxine's effect on liver N-CAM expression.
Main Results:
- Liver N-CAM was identified as a functionally active adhesion molecule.
- Liver N-CAM expression levels correlated with observed changes in cell-to-cell interactions during metamorphosis.
- Thyroxine was found not to be directly involved in the activation of liver N-CAM expression.
Conclusions:
- Liver N-CAM is a functionally active molecule involved in cell adhesion.
- The expression of liver N-CAM dynamically changes during Xenopus laevis metamorphosis, reflecting alterations in cell-to-cell interactions.
- Thyroxine does not directly regulate the expression of liver N-CAM during this developmental process.

01:31Immunoglobulin-like Cell Adhesion Molecules
Immunoglobulin-like cell adhesion molecules or Ig-CAMs are a versatile group of cell surface glycoproteins belonging to the immunoglobulin protein superfamily. Ig-CAMs possess the characteristic immunoglobulin protein domains and other domains such as the fibronectin type III domain. The Ig domains are glycosylated to varying degrees in different Ig-CAMs.
Ig-CAMs exhibit either homophilic binding (to other Ig-CAMs) or heterophilic binding (to other ligands such as integrins). While most Ig-CAMs...

01:58Cell Specific Gene Expression
Multicellular organisms contain a variety of structurally and functionally distinct cell types, but the DNA in all the cells originated from the same parent cells. The differences in the cells can be attributed to the differential gene expression. Liver cells, whose functions include detoxification of blood, production of bile to metabolize fats, and synthesis of proteins essential for metabolism, must express a specific set of genes to perform their functions. Gene expression also varies with...
01:20Cell Adhesion Molecules - Types and Functions
Cell adhesion molecules (CAMs) are pivotal to multicellularity and the coordinated functioning of tissues and organ systems. They enable physical interactions between cells and provide mechanical strength to tissues. They also function as receptors for signal transmission across the plasma membrane. The CAMs are broadly classified into four families - integrins, cadherins, selectins, and immunoglobulin-like CAMs (IgCAMs).

01:24Liver Regeneration
The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.

The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are large...

01:27C4 Pathway and CAM
Most plants use the C3 pathway for carbon fixation. However, some plants, such as sugar cane, corn, and cacti that grow in hot conditions, use alternative pathways to fix carbon and conserve energy loss due to photorespiration. Photorespiration is the process that occurs when the oxygen concentration is high. Under such conditions, the rubisco enzyme in the Calvin cycle binds O2 instead of CO2, which halts photosynthesis and consumes energy.
