Abstract BRAF inhibitors (BRAFi) are used to treat patients with melanoma harboring the V600E mutation. However, resistance BRAFi is inevitable. Here, we identified sphingosine 1-phosphate (S1P) receptors as regulators of BRAFV600E-mutant cell-autonomous BRAFi. Moreover, our results reveal a distinct sphingolipid profile, that is, tendency for increased very long-chain ceramide species, in plasma who achieve response therapy compared progressive disease. Treatment resulted strong decrease...
Triple-negative breast cancer (TNBC) is notoriously aggressive with a high metastatic potential, and targeted therapies are lacking. Using transcriptomic histologic analysis of TNBC samples, we found that expression thrombospondin-1 (TSP1), potent endogenous inhibitor angiogenesis an activator latent transforming growth factor beta (TGF-β), associated (i) gene signatures epithelial-mesenchymal transition TGF-β signaling, (ii) metastasis (iii) reduced survival in patients. In contrast, tumors...
