タイトル Mutant RIT1 cooperates with YAP to drive an EMT-like lung cancer state.
ジャーナル Cell Rep
Abstract Mutations in "Ras-like in all tissues" (RIT1) occur in up to 2% of lung adenocarcinomas and are mutually exclusive with KRAS and EGFR mutations, suggesting that RIT1 may act as a non-canonical driver oncogene in lung cancer. However, the lack of a RIT1-mutant lung cancer model has hindered the development and testing of RIT1-targeted therapeutics. Here, we report a mouse model with conditional regulation of the cancer-associated RIT1M90I variant. We show that autochthonous expression of RIT1M90I and combined inactivation of Nf2 and p53 drives an aggressive lung cancer with 100% penetrance and short latency. Oncogenic cooperation between RIT1M90I and p53/Nf2 loss is driven by synergistic activation of AP-1 transcription factors and can be reversed by the combined inhibition of MEK and TEAD. These data identify YAP/TEAD as a mediator of RIT1's oncogenic capability and nominate TEAD as a potential drug target in RIT1-mutant lung cancer.
