Abstract:
Invasion and metastasis are both the main biological characteristics in malignant tumor which are influence tumor therapeutic effect and prognosis. The tumor cells interact with vascular endothelial cells and cell matrix, penetrate vascular endothelial and degrade the extracellular matrix, and metastasis to the local and distant by the interactions of a variety of signaling molecules. PTEN protein has protein phosphatase and lipid phosphatase dual activity which is produced by PTEN gene. As a tumor suppressor gene, regulates the cell signal pathways to sustain the normal physiological functions, negatively regulates of tumor cell growth and cell cycle, induces apoptosis, and inhibits invasion, infiltrating and metastasis of tumor cells. This article is reviewed about how PTEN participates in inhibiting tumor cell invasion and metastasis.
Insights
The tumor suppressor gene PTEN (Phosphatase and tensin homolog) inhibits cancer invasion and metastasis. This review explores PTEN
Area of Science:
- Oncology
- Molecular Biology
- Biochemistry
Context:
- Malignant tumors are characterized by invasion and metastasis, significantly impacting treatment outcomes and patient prognosis.
- Tumor cell dissemination involves complex interactions with the tumor microenvironment, including endothelial cells and the extracellular matrix.
- Various signaling molecules mediate tumor cell penetration of blood vessels and degradation of extracellular matrix, facilitating metastasis.
Purpose:
- To review the role of PTEN (Phosphatase and tensin homolog) in suppressing tumor cell invasion and metastasis.
- To elucidate the molecular mechanisms by which PTEN regulates cellular processes critical to cancer spread.
Summary:
- PTEN, a tumor suppressor gene, encodes a protein with dual phosphatase activity.
- PTEN negatively regulates key signaling pathways involved in cell growth, cell cycle progression, and apoptosis.
- PTEN actively inhibits tumor cell invasion, infiltration, and metastatic potential.
Impact:
- Understanding PTEN's function provides insights into potential therapeutic strategies targeting cancer metastasis.
- PTEN's role as a tumor suppressor highlights its importance in maintaining normal physiological functions and preventing tumor progression.
- This review consolidates current knowledge on PTEN's anti-metastatic mechanisms, aiding further research in cancer therapy.

Metastasis
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...
