Mitochondrial metabolism determines chemotherapy sensitivity in colorectal cancer
Nature Metabolism, Published online: 23 July 2026; doi:10.1038/s42255-026-01578-wMitochondrial oxidative metabolism is found to strongly affect the response of colorectal cancer (CRC) cells to the chemotherapeutic drug 5-fluorouracil (5FU). Targeting mitochondrial metabolism sensitizes CRC cells to 5FU.

A brief guide to studying extracellular vesicle function in the context of metabolism - Nature Metabolism
Extracellular vesicles (EVs) are now recognized as powerful modulators of metabolism, and thus the new field of EV-mediated metabolic regulation is growing exponentially. Here, we discuss special experimental considerations for the study of EV function in metabolism.

Metabolites are not genes — avoiding the misuse of pathway analysis in metabolomics - Nature Metabolism
Pathway analysis, originally developed for gene expression data, has been adapted for metabolomics. However, owing to the unique characteristics and constraints of metabolites compared with genes, pathway analysis in metabolomics often yields misleading or nonsensical results.
