Phosphatase and tensin homolog (PTEN) is a crucial tumor suppressor gene. This review covers PTEN
Area of Science:
- Oncology
- Molecular Biology
- Biochemistry
Background:
- PTEN, a tumor suppressor gene at 10q23, is frequently lost or mutated in various cancers.
- PTEN acts as a critical phosphatase regulating the PI3K/AKT pathway, which promotes cancer cell survival.
Purpose of the Study:
- To review emerging functions and regulatory mechanisms of PTEN.
- To explore the therapeutic potential of manipulating PTEN in cancer treatment.
Main Methods:
- Literature review of PTEN research.
- Analysis of PTEN's role in cancer signaling pathways.
Main Results:
- PTEN is a nonredundant regulator of the oncogenic PI3K/AKT pathway.
- PTEN loss or mutation is linked to tumor development.
Conclusions:
- Understanding PTEN's diverse functions is key to developing novel cancer therapies.
- Targeting PTEN presents a promising strategy for future cancer treatment.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
