Mutant RAS-driven cancers are infamously resistant to chemotherapeutics. Reporting in Cell, Grabocka and Bar-Sagi (2016) demonstrate that when subjected to stress, mutant KRAS-dependent lipid production leads to upregulated stress granule formation. This confers not only cell-autonomous cytoprotection but also paracrine establishment of a stress-resistant tumor niche.
