Summary
PTEN
Area of Science:
- Molecular Biology
- Cancer Research
- Genetics
Background:
- PTEN (Phosphatase and Tensin Homolog deleted on chromosome 10) is a tumor suppressor.
- PTEN expression levels correlate with its tumor-suppressive functions in various cancers.
- Understanding PTEN regulation is vital for cancer biology.
Purpose of the Study:
- To review identified competing endogenous RNA (ceRNA) partners of PTEN.
- To explore the role of PTEN-centered ceRNA networks in tumorigenesis.
- To elucidate PTEN's coding-independent activities.
Main Methods:
- Literature review of PTEN ceRNA interactions.
- Analysis of molecular mechanisms regulating PTEN expression.
- Discussion of PTEN's role in ceRNA networks.
Main Results:
- Several PTEN ceRNA partners have been identified.
- PTEN mRNA competes with other RNAs for microRNA binding.
- PTEN-centered ceRNA networks influence cancer development.
Conclusions:
- PTEN's regulatory mechanisms involve complex ceRNA interactions.
- PTEN ceRNA networks offer insights into its tumor-suppressive functions.
- Targeting PTEN ceRNA networks may hold therapeutic potential in cancer.

4.7K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

03:03mTOR Signaling and Cancer Progression
5.1K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

7.6K
Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

10.5K
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

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.

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...
