Summary
Galectin-3, a unique protein, plays a key role in tumor progression and metastasis. Its structure allows it to influence cell adhesion, migration, and angiogenesis, crucial processes in cancer spread.
Area of Science:
- Molecular Biology
- Cell Biology
- Biochemistry
Background:
- Galectin-3 is a β-galactoside-binding lectin with a unique chimeric structure.
- It possesses diverse biological functions influenced by its subcellular localization (cytoplasm, nucleus, secreted).
Purpose of the Study:
- To review the multifaceted roles of galectin-3 in biological processes.
- To emphasize galectin-3's specific involvement in tumor metastasis and angiogenesis.
Main Methods:
- Literature review focusing on galectin-3's structure-function relationships.
- Analysis of studies investigating galectin-3's impact on cell behavior and tumor progression.
Main Results:
- Secreted galectin-3 mediates cell migration, adhesion, and interactions.
- Cytoplasmic galectin-3 regulates apoptosis and signaling pathways.
- Nuclear galectin-3 is implicated in pre-mRNA splicing and gene expression.
Conclusions:
- Galectin-3's unique structure enables extensive ligand interactions, modulating critical functions in tumor progression.
- Galectin-3 significantly contributes to tumor metastasis, particularly through its role in angiogenesis.

3.6K
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,...

01:15Activation of Integrins
4.3K
Integrins bind ligands and transmit information from outside the cell to inside or vice-versa through an "outside-in signaling" or "inside-out signaling."
In "outside-in signaling," external factors in the extracellular space bind to exposed ligand binding sites on integrins. This causes the inactive protein to undergo a conformational change to become active. Integrins are often clustered on the cell membrane. Repetitive and regularly spaced ligand binding...

01:10Mechanism of Angiogenesis
6.3K
Blood vessel formation starts early during embryonic development, around day 7. In the extraembryonic yolk sac, mesodermal precursor cells called hemangioblast proliferate and differentiate into angioblast. Angioblasts express vascular endothelial growth factor receptor 2 or VEGFR2, which binds VEGF-A, a proangiogenic factor, guiding blood vessel formation. VEGF signaling promotes angioblasts to form a blood island in the developing embryo. Angioblasts further differentiate, giving rise to...

5.4K
Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

01:24Regulation of Angiogenesis and Blood Supply
2.9K
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

02:38Mitogens and the Cell Cycle
6.3K
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...
