Summary
This summary is machine-generated.Alterations in the CYLD gene are linked to metastasis and poor prognosis in human papilloma virus (HPV)-positive head and neck squamous cell carcinoma (HNSCC). This suggests CYLD mutations may drive aggressive HPV-associated HNSCC progression.
Area Of Science
- Oncology
- Virology
- Genetics
Background
- Human papilloma virus (HPV)-associated head and neck squamous cell carcinoma (HNSCC) is a growing health concern.
- A subset of HPV-positive HNSCC patients exhibit aggressive disease and metastasis.
- The role of frequent CYLD gene alterations in HPV-positive HNSCC progression remains unclear.
Purpose Of The Study
- To investigate the clinical significance of CYLD alterations in HPV-positive HNSCC.
- To understand the impact of CYLD mutations on disease metastasis and patient survival.
Main Methods
- Clinical course assessment of 11 HPV-positive HNSCC patients with CYLD alterations.
- Characterization of a metastatic, HPV-positive HNSCC patient-derived xenograft (PDX) model.
- Functional analysis of specific CYLD mutations (S371* and others).
Main Results
- All 11 patients with CYLD alterations developed metastasis and had reduced overall survival compared to those with wild-type CYLD.
- The metastatic PDX model harbored a CYLD mutation (S371*) and showed decreased connexin 43 expression.
- Functional studies explored the impact of identified CYLD mutations.
Conclusions
- CYLD alterations in HPV-positive HNSCC are significantly associated with metastasis.
- These genetic changes correlate with a poor prognosis in patients with HPV-positive HNSCC.

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...
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,...
The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of cadherin types. Cadherins generally exhibit homophilic binding; i.e., cadherins on one cell bind to cadherins of the same or closely related type on another cell. Thus, cells of the same type have a specific affinity to bind to each other and sort themselves into clusters to form tissues.

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...
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...
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...
