Summary
This summary is machine-generated.Zinc finger and BTB domain-containing protein 11 (ZBTB11) drives lung cancer metastasis by activating matrix metalloproteinase-9 and proline-rich Gla protein 2. Loss of ZBTB11 suppresses metastasis, highlighting its role as a key regulator.
Area Of Science
- Oncology
- Molecular Biology
- Cancer Research
Background
- Metastasis is the primary cause of lung cancer mortality, with underlying mechanisms requiring further elucidation.
- SE translocation (SET) is overexpressed in lung tumors and linked to poor prognosis.
Purpose Of The Study
- To identify and characterize novel prometastatic regulators in lung tumors.
- To elucidate the mechanisms by which ZBTB11 promotes lung cancer metastasis.
Main Methods
- Co-immunoprecipitation and Western blotting to assess protein interactions.
- Quantitative real-time PCR and Western blotting to analyze gene and protein expression.
- In vitro cell migration and invasion assays.
- In vivo lung tumor metastasis mouse model.
Main Results
- ZBTB11 was identified as a SET-associated transcription factor that promotes lung cancer cell migration and invasion.
- The SET-ZBTB11 complex activates matrix metalloproteinase-9 (MMP9) transcription, enhancing metastasis.
- ZBTB11 independently represses proline-rich Gla protein 2 (PRRG2) transcription, linking to Yes-associated protein 1 (YAP1) activation and metastasis.
- ZBTB11 knockdown suppressed distal lung tumor metastasis in vivo.
- ZBTB11 overexpression in human metastatic lung tumors correlated with reduced patient survival.
Conclusions
- ZBTB11 is a critical regulator of lung tumor metastasis through multiple mechanisms.
- Targeting ZBTB11 may offer a therapeutic strategy for inhibiting lung cancer spread.

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.
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...
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...
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,...
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.
Such genes that act...
