Lipidomics and metabolomics dataset for: Methionine metabolism is linked with phospholipid and glutamine metabolism to drive ferroptosis

This deposit provides lipidomics and metabolomics data generated from lung cancer cells under cystine/cysteine deprivation with methionine perturbation (±methionine depletion and ±SAM rescue, where applicable). The deposit includes raw instrument files (when available), aligned/quantified feature tables, identification/annotation outputs, and sample metadata. The accompanying README summarizes experimental groups, replicates, normalization/processing steps, and how each file maps to figures/tables in the manuscript titled 'Methionine metabolism is linked with phospholipid and glutamine metabolism to drive ferroptosis'.
