Although understanding of metabolic reprogramming in melanoma has advanced, the connection between metabolic alterations and metastatic capacity remains incomplete.  \nAim  \nThis study aimed to characterize the metabolic profiles of human melanoma cell lines with high (HT168-M1) and low (WM983B) metastatic potential, and to compare them with each other and also with the metabolic profile of normal human fibroblasts (MRC-5), in order to identify key metabolites and metabolic pathways associated with metastatic behavior.  \nMethods  \nNon-targeted metabolomic profiling using ¹ H-NMR spectroscopy was applied to hydrophilic extracts of the three cell lines. Multivariate statistical analyses (PCA and PLS-DA) were used to identify discriminating metabolites, and pathway analysis was performed to determine altered metabolic networks.  \nResults  \nSeveral metabolic pathways were significantly altered in melanoma cells compared to fibroblasts, including starch and sucrose metabolism, alanine, aspartate and glutamate metabolism, and glutathione metabolism. Metabolites showing more than twofold differences included elevated UDP-glucose, ATP, glycerophosphocholine, GTP,  \nPLOS One | [https://doi.org/10.1371/journal.pone.0352639](https://doi.org/10.1371/journal.pone.0352639) July 1, 2026 1 / 21  \n(2022-2.1.1-NL-2022-00010), the Hungarian Thematic Excellence Program (TKP2021-EGA-44 to J.T. and TKP2021-EGA-24 to A.M.), and the National Research, Development and Innovation Office’s Hungarian Scientific Research Fund (NKFIH-OTKA) grants K147410 (J.T.) .
