| Project Title: | Ranolazine induced metabolic rewiring improves melanoma responses to targeted therapy and immunotherapy |
| Project Summary: | Metabolic rewiring affects resistance of melanoma to targeted- and immuno-therapy. We have found that increased fatty acid oxidation (FAO) during late stages of BRAF inhibitor (BRAFi) treatment enables the establishment of acquired resistance. Targeting FAO with ranolazine in vivo once acquired BRAFi-resistance emerges delays tumour recurrence. Single cell RNAseq analysis revealed that ranolazine diminishes the transcriptional NGFRhigh neural crest stem cell subpopulation, which is refractory against BRAFi and immunotherapy. Moreover, by rewiring the methionine salvage pathway, ranolazine enhanced melanoma immunogenicity through increased antigen presentation and interferon signalling. Combination of ranolazine with anti-PD-L1 antibodies strongly improved survival in mice, where it increased lymphocyte infiltration and enhanced anti-tumour responses. Altogether, we show that ranolazine increases the efficacy of targeted melanoma therapy through fatty acid and methionine salvage metabolic rewiring. Importantly, our study suggests that ranolazine could sensitize BRAFi-resistant tumours to immunotherapy, by modulating melanoma cell recognition and immune infiltration. Ranolazine is an FDA and EMA-approved anti-anginal drug with very mild side effects, and our preclinical data encourage its use as a therapeutic option to improve the two main therapeutic strategies currently used to treat metastatic melanoma. |

Collection:
| Collection ID: | CO002811 |
| Collection Summary: | All cell lines had been authenticated in 2021. Cells were expanded to generate enough vials from a single batch before the start of the study. Cell lines were cultured in Dulbecco’s Eagle’s Medium (DMEM) (cat#61965026, Gibco) supplemented with 10% fetal bovine serum (cat#10500064, Gibco) plus 1% penicillin/streptomycin (cat#15140122, Gibco). Cells were grown at 37°C in a 5% CO2 environment. |
| Sample Type: | Melanoma cells |
Treatment:
| Treatment ID: | TR002827 |
| Treatment Summary: | Melanoma cells seeded in 6-well plates were treated for 7 days with a high dose (5 or 10μM as indicated) of vemurafenib before switching to a lower concentration of the drug (0,5 or 1μM). Fresh medium and vemurafenib was added once weekly for further 3-4 weeks until arising colonies grew to confluence. Fatty Acid oxidation inhibitors ranolazine, etomoxir or thiroridazine were added once a week. |
Sample Preparation:
| Sampleprep ID: | SP002824 |
| Sampleprep Summary: | Lipids from frozen cell pellets were extracted with cold methanol at a concentration of 2 million cells/mL. Samples were vortexed 30 min at 4 degrees C then supernatants clarified by centrifugation (10 min, 10,000 g, 4 degrees C) and transferred to autosampler vials. |
