Moreover, specifically in cells expressing only ARAF, LXH254 caused paradoxical activation of MAPK signaling in a manner similar to dabrafenib. Finally, , LXH254 drove complete regressions of isogenic variants of RAS-mutant cells lacking ARAF expression, while parental lines were only modestly sensitive. LXH254 is a novel RAF inhibitor, which is able to inhibit dimerized BRAF and CRAF, as well as monomeric BRAF, while largely sparing ARAF.

Children are recognised as at lower risk of severe COVID-19 compared with adults, but the impact of immunosuppression is yet to be determined. This study aims to describe the clinical course of COVID-19 in children with kidney disease taking immunosuppressive medication and to assess disease severity. Cross-sectional study hosted by the European Rare Kidney Disease Reference Network and supported by the European, Asian and International paediatric nephrology societies. Anonymised data were submitted online for any child (age <20 years) with COVID-19 taking immunosuppressive medication for a kidney condition. Study recruited for 16 weeks from 15 March 2020 to 05 July 2020. The primary outcome was severity of COVID-19. 113 children were reported in this study from 30 different countries. Median age 13 years (49% male). Main underlying reasons for immunosuppressive therapy kidney transplant (47%), nephrotic syndrome (27%), systemic lupus erythematosus (10%). Immunosuppressive medications used include glhould not be more strictly isolated than children who are not on immunosuppressive therapy.Deubiquitinating enzymes are increasingly recognized to play important roles in cancer, with many acting as oncogenes or tumor suppressors. In this study, we employed a bioinformatics approach to screen for enzymes from this family involved in cancer and found USP24 as a potent predictor of poor outcomes in neuroblastoma, an aggressive childhood cancer. USP24 resides in a region commonly deleted in neuroblastoma, yet was independently associated with poor outcomes in this disease. Deletion of Usp24 in a murine model resulted in degradation of collapsin response mediator protein 2 (CRMP2), a regulator of axon growth, guidance, and neuronal polarity. Cells lacking USP24 had significant increases in spindle defects, chromosome missegregation, and aneuploidy, phenotypes that were rescued by the restoration of CRMP2. USP24 prevented aneuploidy by maintaining spindle-associated CRMP2, which is required for mitotic accuracy. Our findings further indicate that USP24 is a tumor suppressor that may play an important role in the pathogenesis of neuroblastoma. SIGNIFICANCE This study identifies the chromosome instability gene USP24 as frequently deleted in neuroblastoma and provides important insight into the pathogenesis of this aggressive childhood cancer.Plasma protein-mediated uptake (PMU) and its effect on clearance (CL) prediction have been studied in various formats; however, a comprehensive analysis of the overall impact of PMU on CL parameters from hepatocyte assays (routinely used for IVIVE) has not previously been performed. The following work collated data reflecting the effect of PMU for 26 compounds with a wide variety of physicochemical, drug, and in vivo CL properties. PMU enhanced the unbound intrinsic clearance in vitro (CLint,u in vitro) beyond that conventionally calculated using fraction unbound and was correlated with the unbound fraction of drug in vitro and in plasma (fup) and absolute unbound intrinsic clearance in vivo (CLint,u in vivo) in both rat and human hepatocytes. PMU appeared to be more important for highly bound (fup 50% of compounds predicted within a 2-fold error for both rat and human data sets (n ≥ 100). SIGNIFICANCE STATEMENT Current strategies for prediction of hepatic clearance from i
