Ten-eleven translocation 1 (TET1) is crucial in cancer biology, acting as a tumor suppressor. Further research is needed to understand its complex roles in tumorigenesis and progression for potential therapeutic applications.
Area of Science:
- Molecular Biology
- Cancer Biology
- Epigenetics
Background:
- Aberrant expression of ten-eleven translocation 1 (TET1) is implicated in tumor development and progression.
- TET1 is a key enzyme in DNA demethylation, converting 5-methylcytosine to 5-hydroxymethylcytosine.
Purpose of the Study:
- To systematically summarize the latest research on the role and mechanisms of TET1 in cancer biology.
- To explore TET1's function beyond its enzymatic activity in tumorigenesis.
Main Methods:
- Literature review of articles from 1980 to April 2016.
- Searched PubMed using terms: "ten-eleven translocation 1," "5mC," "5hmC," "microRNA," "hypoxia," and "embryonic stem cell."
- Included clinical and basic research articles focusing on TET1's role in tumors.
Main Results:
- Loss of TET1 is associated with tumorigenesis, suggesting it acts as a tumor suppressor gene and potential therapeutic biomarker.
- TET1 influences epithelial-mesenchymal transition and regulates gene transcription, including developmental regulators in embryonic stem cells (ESCs) and hypoxia-responsive genes in cancer.
- TET1 regulation is linked to microRNA-mediated posttranscriptional modifications.
Conclusions:
- TET1 has multifaceted roles in tumorigenesis and progression, extending beyond its demethylation function.
- Elucidating the precise mechanisms of TET1 in cancer biology is critical for its development as a therapeutic tool.

Cancer-Critical Genes I: Proto-oncogenes
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.

When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...
