Decreased TET2 gene expression during chronic myeloid leukemia progression
Leukemia Research
|July 29, 2011
Summary
Ten-eleven-translocation-2 (TET2) gene alterations are key in myeloid cancers. This study found a TET2 deletion, not a mutation, causing reduced gene expression in chronic myeloid leukemia progression.
Area of Science:
- Hematology
- Cancer Genetics
- Molecular Biology
Background:
- Ten-eleven-translocation-2 (TET2) gene alterations are increasingly recognized as critical in myeloid malignancies.
- Previously, TET2 dysfunction was primarily attributed to mutations within its coding regions.
Observation:
- A unique case of chronic myeloid leukemia (CML) exhibited a TET2 single copy partial deletion.
- This deletion was associated with a t(4;6;11) chromosomal rearrangement and emerged during disease progression.
Findings:
- The observed TET2 deletion led to significantly decreased TET2 gene expression.
- This contrasts with the previously understood mechanisms of TET2 loss-of-function.
Implications:
- The findings suggest TET2 haploinsufficiency as a potential driver in CML progression.
- This expands the known spectrum of genetic alterations affecting TET2 in hematological cancers.

02:23Abnormal Proliferation
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
02:23Master Transcription Regulators
Master transcription regulators are regulatory proteins that are predominantly responsible for regulating the expression of multiple genes. Often these genes work in concert to drive a complex process. Activation of a master transcription regulator can lead to a cascade of transcriptional activation necessary for that outcome. These regulators can directly bind to the regulatory sequences of the various genes involved, or they can indirectly regulate transcription by binding to regulatory...
