dc.description.abstractCIC (also known as Capicua) is a transcriptional repressor negatively regulated by RAS/MAPK signaling. Whereas the functions of Cic have been well characterized in Drosophila, little is known about its role in mammals. CIC is inactivated in a variety of human tumors and has been implicated recently in the promotion of lung metastases. Here, we describe a mouse model in which we inactivated Cic by selectively disabling its DNA-binding activity, a mutation that causes derepression of its target genes. Germline Cic inactivation causes perinatal lethality due to lung differentiation defects. However, its systemic inactivation in adult mice induces T-cell acute lymphoblastic lymphoma (T-ALL), a tumor type known to carry CIC mutations, albeit with low incidence. Cic inactivation in mice induces T-ALL by a mechanism involving derepression of its well-known target, Etv4 Importantly, human T-ALL also relies on ETV4 expression for maintaining its oncogenic phenotype. Moreover, Cic inactivation renders T-ALL insensitive to MEK inhibitors in both mouse and human cell lines. Finally, we show that Ras-induced mouse T-ALL as well as human T-ALL carrying mutations in the RAS/MAPK pathway display a genetic signature indicative of Cic inactivation. These observations illustrate that CIC inactivation plays a key role in this human malignancy.es_ES

dc.description.sponsorshipWe are grateful to Carol MacKintosh (University of Dundee, UK) for the pcDNA5/FRT/TO-GFP-CIC plasmid, and Huda Zoghbi (Baylor College of Medicine, Houston, TX) and Yoontae Lee (University of Pohang, Korea) for Cic antisera. We thank Scott Brown and Robert Holt (University of Vancouver, Canada) for their help with TCR abundance calculations. We also thank Carmen G. Lechuga, Marta San Roman, Raquel Villar, Beatriz Jimenez, and Nuria Cabrera for excellent technical assistance. We value the support of Sagrario Ortega (Transgenic Mice Core Unit, CNIO) for help in generating the Cic mutant mice, Orlando Dominguez (Genomics Core Unit, CNIO) for the RNA-seq analysis, and the Histopathology Core Unit.
