Abstract:
Cytoplasmic polyadenylation element-binding protein-4 (CPEB4) is involved in several biological processes that are associated with cancer progression. However, it remains unknown whether CPEB4 expression levels are associated with head and neck squamous cell carcinoma (HNSCC). The aim of the present study was to explore the potential function of CPEB4 in HNSCC. The expression of CPEB4 was analyzed in HNSCC from six Gene Expression Omnibus (GEO) datasets. Immunohistochemical staining was conducted to examine CPEB4 protein levels in an HNSCC tissue microarray (TMA). According to the GEO dataset analyses, CPEB4 gene expression was downregulated in HNSCC compared with normal samples (P<0.05). Notably, a statistical difference was observed between different tumor grades (P<0.05). Furthermore, the methylation of the CPEB4 gene in HNSCC was significantly increased compared with that observed in normal samples (P<0.01). The outcome from the TMA demonstrated that CPEB4 protein expression in human HNSCC tumors was significantly decreased compared with normal samples (P<0.05). In addition, the expression of CPEB4 protein was negatively associated with histological grades of HNSCC (P<0.05). The results from the present study suggested that CPEB4 may function as a tumor suppressor gene in HNSCC, which identifies the potential value of CPEB4 in predicting prognosis of HNSCC. Hypermethylation of the CPEB4 gene may be responsible for the downregulation of CPEB4 expression in HNSCC and result in tumorigenesis.
Insights
Cytoplasmic polyadenylation element-binding protein-4 (CPEB4) is downregulated in head and neck squamous cell carcinoma (HNSCC). This suggests CPEB4 may act as a tumor suppressor, offering potential for HNSCC prognosis.
Area of Science:
- Oncology
- Molecular Biology
- Cancer Research
Background:
- Cytoplasmic polyadenylation element-binding protein-4 (CPEB4) plays a role in cancer progression.
- The association between CPEB4 expression and head and neck squamous cell carcinoma (HNSCC) is not well understood.
Purpose of the Study:
- To investigate the role of CPEB4 in HNSCC.
- To analyze CPEB4 expression levels and their correlation with clinicopathological features in HNSCC.
Main Methods:
- Analysis of CPEB4 gene expression in six Gene Expression Omnibus (GEO) datasets.
- Immunohistochemical staining of CPEB4 protein in an HNSCC tissue microarray (TMA).
- Assessment of CPEB4 gene methylation in HNSCC samples.
Main Results:
- *CPEB4* gene expression was significantly downregulated in HNSCC compared to normal tissues.
- CPEB4 protein levels were decreased in HNSCC tumors and negatively correlated with histological grade.
- Increased methylation of the *CPEB4* gene was observed in HNSCC, suggesting a mechanism for its downregulation.
Conclusions:
- CPEB4 may function as a tumor suppressor gene in HNSCC.
- Downregulation of CPEB4, potentially due to hypermethylation, contributes to HNSCC tumorigenesis.
- CPEB4 holds potential as a prognostic biomarker for HNSCC.
