    The yin–yang of kinase activation and unfolding explains the peculiarity of Val600 in the activation segment of BRAF

    Christina Kiel, Hannah Benisty ... Luis Serrano
    The V600E mutation in BRAF is a cancer hot spot because it opens the activation segment through destabilization of autoinhibitory interactions, but it does not significantly impair folding of the inactive or active kinase domain.

    BRAFV600E cooperates with CDX2 inactivation to promote serrated colorectal tumorigenesis

    Naoya Sakamoto, Ying Feng ... Eric R Fearon
    Genetic analyses reveal how CDX2 and BRAF defects seen in serrated colorectal cancer (CRCs), a poor prognosis CRC subset, cooperate in tumorigenesis in humans and in a mouse cancer model.

    BRAFV600E induces reversible mitotic arrest in human melanocytes via microRNA-mediated suppression of AURKB

    Andrew S McNeal, Rachel L Belote ... Robert L Judson-Torres
    Oncogenic BRAF causes genome duplication and reversible growth arrest in human melanocytes that is conditional on microRNA expression and differentiation state.

    Autophagy inhibition overcomes multiple mechanisms of resistance to BRAF inhibition in brain tumors

    Jean M Mulcahy Levy, Shadi Zahedi ... Andrew Thorburn
    Pre-clinical and patient data show that inhibition of autophagy with an approved, inexpensive, well-tolerated drug can overcome resistance to BRAFV600E inhibition in multiple brain tumor subtypes with different resistance mechanisms.

    RNF43 inhibits WNT5A-driven signaling and suppresses melanoma invasion and resistance to the targeted therapy

    Tomasz Radaszkiewicz, Michaela Nosková ... Vítězslav Bryja
    RNF43 interacts with receptor complexes of the Wnt/PCP signaling and its enzymatic activity results in the reduced cells sensitivity to WNT5A what translates in melanoma into decreased invasive properties and increased response to targeted therapies of this skin cancer.

    Oncogenic BRAF disrupts thyroid morphogenesis and function via twist expression

    Viviana Anelli, Jacques A Villefranc ... Yariv Houvras
    Transformation mediated by oncogenic BRAF requires transcriptional activation of TWIST at the earliest stage of neoplastic transformation.

    An NKX2-1/ERK/WNT feedback loop modulates gastric identity and response to targeted therapy in lung adenocarcinoma

    Rediet Zewdu, Elnaz Mirzaei Mehrabad ... Eric L Snyder
    Genetically engineered murine models reveal novel mechanisms of cell identity regulation in lung cancer and provide insights into the complex interplay between lineage specifiers and oncogenic signaling pathways in this disease.

    MAPK activity dynamics regulate non-cell autonomous effects of oncogene expression

    Timothy J Aikin, Amy F Peterson ... Sergi Regot
    The temporal patterns of MAPK activity differentially regulate cell autonomous and non-cell autonomous effects of oncogene expression.
