Metabolomics and NMR Spectroscopy in Cancer Biology

Metabolomics, the comprehensive analysis of small-molecule metabolites within cells, tissues and biofluids, has emerged as a pivotal discipline in cancer biology. By charting metabolic fingerprints, researchers can uncover alterations in energy production, biosynthetic pathways and signalling networks that arise during malignant transformation. Nuclear magnetic resonance (NMR) spectroscopy offers a powerful platform for metabolomic investigations, providing non-destructive, quantitative and structurally informative insights into a tumour’s chemical milieu. High-field NMR and clinical proton MR spectroscopy (1H-MRS) have been instrumental in linking aberrant metabolite levels to oncogenic drivers, tumour grade and therapeutic response. Together, metabolomics and NMR spectroscopy enable a systems-level understanding of cancer metabolism, guide biomarker discovery and inform novel treatment strategies that target metabolic vulnerabilities.

Research from Nature Portfolio

Recent studies have employed high-resolution ex vivo 1H-NMR to dissect the metabolic heterogeneity of pituitary adenomas. By analysing resected tumour tissue, investigators identified subtype-specific variations in compounds such as N-acetylaspartate, myo-inositol and phosphoethanolamine, highlighting metabolic signatures that correlate with hormone secretion profiles. In parallel, quantitative NMR of serum samples from patients with distinct pituitary tumour subtypes revealed elevated circulating levels of beta-hydroxybutyrate in prolactinomas compared with gonadotroph adenomas. This work demonstrates the utility of NMR-based metabolomics for non-invasive subclassification and suggests that ketone bodies may serve as blood-borne markers to augment conventional hormone assays.

Technical terms

Metabolomics: The large-scale study of metabolites—small molecules such as sugars, lipids and amino acids—in biological systems to understand metabolic changes associated with disease states.

Nuclear magnetic resonance (NMR) spectroscopy: A technique that exploits the magnetic properties of atomic nuclei to provide structural and quantitative information on molecules in solution or solid form.

Proton MR spectroscopy (1H-MRS): A non-invasive in vivo NMR method that measures the resonance frequencies of hydrogen atoms in metabolites, used clinically to assess tissue biochemistry.

Non-targeted metabolomics: An analytical approach that aims to detect and quantify as many metabolites as possible in a sample without prior selection, often using mass spectrometry or NMR.
