Summary
Galectin-7, a protein mainly in epithelial tissues, plays roles in cell processes. Its altered expression in carcinomas suggests involvement in cancer progression, though its exact functions require further study.
Area of Science:
- Molecular Biology
- Cell Biology
- Cancer Research
Background:
- Galectins are soluble lectins recognizing carbohydrates, with diverse roles inside and outside cells.
- Galectin-7, mainly expressed in stratified epithelia, influences apoptosis, proliferation, differentiation, adhesion, and migration.
- Galectins are implicated in cancer biology, particularly in immune modulation, angiogenesis, and tumor cell migration.
Purpose of the Study:
- To review the physiological functions of galectin-7 in epithelial tissues.
- To examine the altered expression of galectin-7 in carcinomas.
- To elucidate the potential functions of galectin-7 in tumor progression and metastasis.
Main Methods:
- Literature review of galectin-7's physiological roles in epithelia.
- Analysis of studies reporting galectin-7 expression changes in various carcinomas.
- Synthesis of current knowledge on galectin-7's involvement in cancer biology.
Main Results:
- Galectin-7 is crucial for normal epithelial cell functions.
- Abnormal galectin-7 expression is frequently observed in carcinomas.
- Galectin-7 is implicated in cancer progression and metastasis, but its precise mechanisms are not fully understood.
Conclusions:
- Galectin-7's dysregulation in cancer highlights its potential as a biomarker or therapeutic target.
- Further research is needed to fully understand galectin-7's multifaceted roles in tumor development.
- Investigating galectin-7 functions may offer new insights into carcinoma treatment strategies.

01:19Cadherins in Tissue Organization
4.3K
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.

01:22Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal
2.7K
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.

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).

01:12Role Of Notch Signalling In Intestinal Stem Cell Renewal
2.5K
Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...

4.3K
Cell adhesion is an essential aspect of multicellularity. While stable cell interactions usually occur between cells of the same type, transient cell interactions occur between cells of different tissue types, such as between neutrophils and endothelial cells. Selectins are one class of cell adhesion molecules (CAMs) that bind carbohydrate ligands to form transient cell adhesion. They are rod-like proteins with a long extracellular part of variable length ending with the lectin domain,...

01:23Epithelial Tissues and Their Functions
41.5K
Epithelial tissues are large sheets of cells covering all of the surfaces of the body. These surfaces can be internal or external, for example, skin, airways, the digestive tract, the urinary system, and the reproductive system. Hollow organs and body cavities that do not connect to the body's exterior, including blood vessels and serous membranes, are lined by epithelial tissue known as the endothelium.
