Abstract:
Radiotherapy and chemotherapy have improved the 5-year survival rate of nasopharyngeal carcinoma (NPC) patients, but the side effects generally lead to unsatisfactory clinical efficacy. It's imperative to explore the pathogenesis of NPC to find better diagnostic and therapeutic methods. Small nucleolar RNA host genes (SNHGs) are special lncRNAs, which can be further spliced to produce small nucleolar RNAs (snoRNAs). SNHG1 has been found to be associated with various cancers. However, only a few studies reported the relationship between SNHG1 and NPC. This study first analyzed the diagnostic performance and related signaling pathways of SNHG1 in NPC through bioinformatics. The expression of SNHG1 was verified by RT-qPCR, and the expression of the signaling pathway was detected using immunohistochemistry. Bioinformatics analysis results showed that SNHG1 was significantly overexpressed in head and neck squamous cell carcinoma (HNSC) and NPC tissues. RT-qPCR detection confirmed the significant overexpression of SNHG1 in NPC tissues. Enrichment analysis showed that SNHG1 may act on NPC through the PI3K-AKT signaling pathway. Immunohistochemistry experiment revealed PI3K-AKT signaling pathway proteins (PI3K AKT and EGFR) positively expressed and CASP3 weakly positively expressed in NPC tissues. Therefore, we concluded that SNHG1 is a prospective biomarker and may act on NPC through the PI3K-AKT signaling pathway.
Insights
Small nucleolar RNA host gene 1 (SNHG1) is overexpressed in nasopharyngeal carcinoma (NPC), suggesting its potential as a diagnostic biomarker. SNHG1 may influence NPC progression via the PI3K-AKT signaling pathway.
Area of Science:
- Oncology
- Molecular Biology
- Biochemistry
Background:
- Nasopharyngeal carcinoma (NPC) treatments have limitations due to side effects.
- Small nucleolar RNA host genes (SNHGs) are emerging as key players in various cancers.
- Limited research exists on the role of SNHG1 in NPC pathogenesis.
Purpose of the Study:
- To investigate the diagnostic potential of SNHG1 in NPC.
- To explore the signaling pathways implicated in SNHG1-mediated NPC progression.
- To validate SNHG1 expression and pathway involvement in NPC tissues.
Main Methods:
- Bioinformatic analysis of SNHG1 expression and associated pathways in NPC and head and neck squamous cell carcinoma (HNSC).
- Reverse transcription quantitative polymerase chain reaction (RT-qPCR) to confirm SNHG1 expression in NPC tissues.
- Immunohistochemistry to detect the expression of key proteins in the PI3K-AKT signaling pathway (PI3K, AKT, EGFR) and CASP3.
Main Results:
- SNHG1 was found to be significantly overexpressed in both HNSC and NPC tissues.
- RT-qPCR confirmed the significant overexpression of SNHG1 in NPC tissues.
- Bioinformatic and experimental results suggest SNHG1's involvement in NPC through the PI3K-AKT signaling pathway, with positive expression of PI3K, AKT, EGFR, and weak positive expression of CASP3 in NPC tissues.
Conclusions:
- SNHG1 is a potential diagnostic biomarker for NPC.
- SNHG1 may contribute to NPC development and progression via the PI3K-AKT signaling pathway.
