When SUCNR1/GPR91-expressing macrophages are activated by inflammatory signals, they change their metabolism and accumulate succinate. In this study, we show that during activation, release succinate into the extracellular milieu. They simultaneously up-regulate GPR91, which functions as an autocrine paracrine sensor for to enhance IL-1β production. GPR91-deficient mice lack metabolic reduced macrophage activation production of antigen-induced arthritis. Succinate is abundant in synovial...

Abstract Transcription factor networks shape the gene expression programs responsible for normal cell identity and pathogenic state. Using Core Regulatory Circuitry analysis (CRC), we identify PAX8 as a candidate oncogene in Renal Cell Carcinoma (RCC) cells. Validation of large-scale functional genomic screens confirms that silencing leads to decreased proliferation RCC lines. Epigenomic analyses PAX8-dependent cistrome demonstrate largely occupies active enhancer elements controlling genes...

Abstract The transcription factor PAX8 is critical for the development of thyroid and urogenital system. Comprehensive genomic screens furthermore indicate an additional oncogenic role in renal ovarian cancers. While a plethora PAX8-regulated genes different contexts have been proposed, we still lack mechanistic understanding how engages molecular complexes to drive disease-relevant transcriptional programs. Here show that protein isoforms originating from MECOM locus form complex with PAX8....

Asparagine deprivation by l-asparaginase (L-ASNase) is an effective therapeutic strategy in acute lymphoblastic leukemia, with resistance occurring due to upregulation of ASNS, the only human enzyme synthetizing asparagine (Annu. Rev. Biochem.2006, 75 (1), 629-654). l-Asparaginase efficacy solid tumors limited dose-related toxicities (OncoTargets and Therapy 2017, pp 1413-1422). Large-scale loss function genetic vitro screens identified ASNS as a cancer dependency several malignancies...
