Only lipids with a median fold change between parental and A375VR cells of p ≤ 0.05 ( n = 4, two-tailed unpaired t -test) are shown. E Heatmap showing MAGIC expression z-scores of ferroptosis regulator genes, with cells ordered using hierarchical clustering applied both within and between Seurat clusters, and colour-coded by parental or VR sample identity.

H Uniform Manifold Approximation and Projection (UMAP) visualisation of parental A375 and A375VR cells coloured by the expression of ferroptosis regulators shown in ( E ) or the expression of the Tsoi undifferentiated (UD) state . I Discrete expression of the Tsoi UD state as well as of FAO regulators based on the 90th percentile of signature scores across the whole dataset. J Biological functions enriched (based on hypergeometric tests) in the top 200 most overexpressed genes of FAO-high cells as defined ( I ) compared to the remaining cells. The dashed line indicates p = 0.05.

Figure Legend Snippet: A Growth curves of A375 tumours from mice treated with BRAFi (25 mg/kg, daily) and RANO (50 mg/kg, daily) as described . Tumours had been allowed to grow until resistance against BRAFi (VR, n = 8) or against BRAFi + RANO (VR-RAN n-R, n = 4) was established. Tumours that still responded to BRAFi + RANO were classified as VR-RAN R ( n = 4). B Tumour volume at endpoint of the experiment. (Mean ± SEM, Tukey test of one-way ANOVA. ** p -value ≤ 0.01). C RT-qPCR analysis of the indicated genes in A375 tumours from mice treated as indicated. Data are triplicates from n = 8 tumours for vehicle (veh) or BRAFi (VR), and n = 4 tumours for RANO responder (R) or RANO non-responders (n-R). (Mean ± SEM, uncorrected Fisher’s LSD test of one-way ANOVA. * p -value ≤ 0.05; ** p -value ≤ 0.01; **** p -value ≤ 0.0001).
