The lipid profile is altered in endocrine resistant breast cancer cells. a-b) Principal component analysis (PCA) plots of T47D (a) and UCD4 (b) parental (Par) and endocrine resistant cell samples (quadruplicate) profiled by mass spectrometry-based lipidomics. c-d) Venn diagrams of significantly altered lipid analytes (up- and downregulated, q < 0.05) in T47D-TamR and -FulvR (c) and UCD4-TamR, -FulvR, and -EWD cells (d) compared to Par cells. e-f) Heatmaps of the top 25 significantly altered shared lipid analytes (up- or downregulated, PLS-DA VIP supervised clustering) between, (e) T47D-TamR and -FulvR cells, and (f) UCD4-TamR, -FulvR, and -EWD cells compared to Par cells. Plots were generated using MetaboAnalyst
