1H HR‐MAS NMR Metabolomics in Combination With Transcriptomic Correlation Provides New Insights Into Metabolic Heterogeneity Across Breast Cancer Immunohistochemical Subtypes

NMR in Biomedicine, Volume 39, Issue 10, October 2026.
Metabolomic profiling of breast cancer tissue using 1H HR‐MAS NMR spectroscopy and LCModel‐based quantitative analysis revealed metabolite differences associated with immunohistochemical subtypes, and subsequent metabolomics–transcriptomics integration linked these subtype‐dependent metabolic signatures to pathways in choline metabolism, one‐carbon ...

Ascorbate Metabolism in Potato Leaves Supplied with Exogenous Ascorbate

Free Radical Research, 1999
Photosynthesis and leaf ascorbate were measured in potato (Solanum tuberosum L.) plants grown in low light and then transferred to high light. Total foliar ascorbate content in low light-grown plants was 4.72+/-0.42 micromol mg(-1)chl. Over 80% of the ascorbate pool was found in the reduced form irrespective of position on the stem.
