    SIRT6 regulates Ras-related protein R-Ras2 by lysine defatty-acylation

    Xiaoyu Zhang et al.
    A posttranslational regulatory mechanism for a Ras family small GTPase could open up new directions to understand and control the Ras family of proteins that are important for physiology and diseases.

    KRAS-dependent sorting of miRNA to exosomes

    Diana J Cha et al.
    In isogenically matched colorectal cancer (CRC) cell lines, mutant KRAS alters the composition of secreted miRNAs in extracellular vesicles that can then transfer repressive activity to wild type cells.

    Hyperactivation of ERK by multiple mechanisms is toxic to RTK-RAS mutation-driven lung adenocarcinoma cells

    Arun M Unni et al.
    Cancer cells driven by mutations in KRAS or EGFR are dependent on DUSP6 to prevent ERK-induced cell death, creating a novel vulnerability for targeted therapy.

    Specific cancer-associated mutations in the switch III region of Ras increase tumorigenicity by nanocluster augmentation

    Maja Šolman et al.
    Rare mutations in the switch III region of Ras can increase its nanoscale clustering, which enhances effector recruitment and downstream signaling.

    Targeting RAS-driven human cancer cells with antibodies to upregulated and essential cell-surface proteins

    Alexander J Martinko et al.
    Proteomics and functional genomics coupled to an antibody discovery pipeline revealed the influence of oncogenic RAS signaling on the cell-surface proteome and resulted in the discovery of potential therapeutic targets for RAS-driven cancers.

    Developmental lineage priming in Dictyostelium by heterogeneous Ras activation

    Alex Chattwood et al.
    The probability of a cellular response to a differentiation inducing signal is correlated with the dynamic expression of a Ras protein, and produces a ‘salt and pepper’ pattern of cell differentiation.

    BRET-based RAS biosensors that show a novel small molecule is an inhibitor of RAS-effector protein-protein interactions

    Nicolas Bery et al.
    A biosensor resource has been developed to monitor the intracellular interactions of RAS family proteins with effector molecules and the effects of inhibitors as an aid to drug development.

    A KRAS-directed transcriptional silencing pathway that mediates the CpG island methylator phenotype

    Ryan W Serra et al.
    A pathway directed by the KRAS oncoprotein leads to aberrant hypermethylation and transcriptional silencing of many genes including tumor suppressors, thereby promoting tumor development.

    MicroRNA-203 represses selection and expansion of oncogenic Hras transformed tumor initiating cells

    Kent Riemondy et al.
    Inhibition of microRNA-203 by oncogenic HRas mutations promotes skin cancer initiation.

    Impairment of cocaine-mediated behaviours in mice by clinically relevant Ras-ERK inhibitors

    Alessandro Papale et al.
    Two cell-penetrating peptides that inhibit Ras-ERK signalling and a potent clinically relevant MEK inhibitor block cocaine conditioned place preference and accelerate extinction of cocaine self-administration upon a single administration in mice.
