Study on Differential Metabolites Between Human Papillomavirus Infection and Cervical Cancer Based on Non-Targeted...

Area of Science:

• Metabolomics
• Biochemistry
• Oncology

Background:

• Cervical cancer is a significant global health concern.
• Human papillomavirus (HPV) infection is a primary cause of cervical cancer.
• Understanding metabolic alterations in cervical carcinogenesis is crucial for early detection and treatment.

Purpose of the Study:

• To investigate differential metabolite profiles in HPV infection and cervical cancer progression.
• To identify potential metabolic biomarkers for cervical cancer detection and development.

Main Methods:

• Non-targeted metabolomics using ultra-high-performance liquid chromatography and SCIEX mass spectrometry.
• Analysis of metabolites in women with HPV-negative status, HPV infection (LSIL), cervical intraepithelial neoplasia (CIN2-3), and cervical cancer.
• KEGG pathway enrichment analysis to identify significantly altered metabolic pathways.

Main Results:

• Steroid hormone and glycerophosphate metabolism pathways were significantly enriched in CIN2-3 compared to HPV-negative and HPV-positive groups.
• Sphingolipid metabolism and steroid biosynthesis pathways were altered in cervical cancer compared to earlier stages.
• 19-Hydroxytestosterone, cerebroside B, potassium acetate, and methylarsonate showed downregulated expression with increasing cervical lesion severity.

Conclusions:

• Metabolic pathway alterations, particularly in steroid hormone and sphingolipid metabolism, are associated with cervical cancer development.
• Downregulated expression of 19-Hydroxytestosterone, cerebroside B, potassium acetate, and methylarsonate suggests their potential as biomarkers for cervical cancer.
