A pilot metabolomics study on clear cell renal cell carcinoma

Area of Science:

• Oncology
• Metabolomics
• Biochemistry

Background:

• Clear cell renal cell carcinoma (ccRCC) is recognized as a metabolic disease.
• Understanding metabolic alterations is crucial for diagnosing and treating ccRCC.

Purpose of the Study:

• To investigate metabolic changes in ccRCC using untargeted metabolomics.
• To identify potential diagnostic biomarkers for ccRCC.

Main Methods:

• Analyzed 15 ccRCC samples and paired adjacent non-malignant tissues.
• Utilized ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) for untargeted metabolomics.
• Performed KEGG pathway enrichment analysis.

Main Results:

• Screened 511 differential metabolites between ccRCC and normal tissues.
• Identified significantly up-regulated metabolites including histamine, cortisol, and citric acid.
• Identified significantly down-regulated metabolites such as D-cysteine, acetylcholine, and pantothenic acid.
• Highlighted pathways include steroid hormone biosynthesis, pyrimidine metabolism, and vitamin digestion and absorption.

Conclusions:

• ccRCC exhibits distinct metabolic patterns.
• Metabolite profiles and pathways identified may serve as potential biomarkers for ccRCC diagnosis.
