Background:
Ribosomal proteins are traditionally associated with protein biosynthesis until recent studies that implicated their extraribosomal functions in human diseases and cancers. Our previous studies using GeneFishing™ DEG method and microarray revealed underexpression of three ribosomal protein genes, RPS26, RPS27, and RPL32 in cancer of the nasopharynx. Herein, we investigated the expression pattern and nucleotide sequence integrity of these genes in nasopharyngeal carcinoma to further delineate their involvement in tumourigenesis. The relationship of expression level with clinicopathologic factors was also statistically studied.
Methods:
Quantitative Polymerase Chain Reaction was performed on nasopharyngeal carcinoma and their paired normal tissues. Expression and sequence of these three genes were analysed.
Results:
All three ribosomal protein genes showed no significant difference in transcript expressions and no association could be established with clinicopathologic factors studied. No nucleotide aberrancy was detected in the coding regions of these genes.
Conclusion:
There is no early evidence to substantiate possible involvement of RPS26, RPS27, and RPL32 genes in NPC tumourigenesis.
Insights
This study found no significant differences in the expression or sequence of ribosomal protein genes RPS26, RPS27, and RPL32 in nasopharyngeal carcinoma. Therefore, these genes do not appear to be involved in NPC tumor development.
Area of Science:
- Molecular Biology
- Oncology
- Genetics
Background:
- Ribosomal proteins traditionally aid protein biosynthesis.
- Emerging research highlights their extraribosomal roles in diseases, including cancer.
- Previous work indicated underexpression of RPS26, RPS27, and RPL32 in nasopharyngeal carcinoma.
Purpose of the Study:
- Investigate the expression patterns and nucleotide sequence integrity of RPS26, RPS27, and RPL32 in nasopharyngeal carcinoma.
- Determine the relationship between the expression levels of these genes and clinicopathologic factors.
- Clarify the potential involvement of these ribosomal protein genes in nasopharyngeal carcinoma tumorigenesis.
Main Methods:
- Quantitative Polymerase Chain Reaction (qPCR) was employed.
- Analysis was conducted on nasopharyngeal carcinoma tissues and their paired normal counterparts.
- Expression levels and nucleotide sequences of RPS26, RPS27, and RPL32 were examined.
Main Results:
- No significant differences in transcript expression were observed for RPS26, RPS27, and RPL32.
- No association was found between the expression of these genes and the studied clinicopathologic factors.
- No nucleotide aberrations were detected within the coding regions of these three genes.
Conclusions:
- Current findings do not provide evidence for the involvement of RPS26, RPS27, and RPL32 in the early stages of nasopharyngeal carcinoma (NPC) tumorigenesis.
- The study suggests that these specific ribosomal protein genes may not play a direct role in NPC development.
- Further research may be needed to explore other potential mechanisms or genes in NPC pathogenesis.

Ribosomal RNA Synthesis
Ribosome biogenesis begins with the synthesis of 5S and 45S pre-rRNAs by distinct RNA polymerases. The primary transcripts are extensively processed and modified before they are bound and folded by ribosomal proteins and assembly factors,...
