AKT3-mediated IWS1 phosphorylation promotes the proliferation of EGFR-mutant lung adenocarcinomas through cell cycle-regulated U2AF2 RNA splicing.

Nat Commun 2021 Jul 30;12(1):4624. Epub 2021 Jul 30.

Department of Cancer Biology and Genetics, The Ohio State University, Columbus, OH, USA.

AKT-phosphorylated IWS1 regulates alternative RNA splicing via a pathway that is active in lung cancer. RNA-seq studies in lung adenocarcinoma cells lacking phosphorylated IWS1, identified a exon 2-deficient U2AF2 splice variant. Here, we show that exon 2 inclusion in the U2AF2 mRNA is a cell cycle-dependent process that is regulated by LEDGF/SRSF1 splicing complexes, whose assembly is controlled by the IWS1 phosphorylation-dependent deposition of histone H3K36me3 marks in the body of target genes.

Consideration of antimicrobial resistance and contextual factors in infectious disease guidelines: a systematic survey.

BMJ Open 2021 Jul 30;11(7):e046097. Epub 2021 Jul 30.

Department of Health Research Methods, Evidence and Impact, McMaster University, Hamilton, Ontario, Canada

Objectives: Guidelines that include antimicrobial recommendations should explicitly consider contextual factors that influence antimicrobial resistance and their downstream effects on resistance selection.

Ki-67 immunoexpression and radiological assessment of necrosis improves accuracy of conventional and modified core biopsy systems in predicting the final grade assigned to adult-soft tissue sarcomas. An international collaborative study.

Pathol Res Pract 2021 Jul 22;225:153562. Epub 2021 Jul 22.

Pathology Department, University of Valencia, Valencia, Spain.

Based on the French Federation Nationale des Centers de Lutte Contre le Cancer (FNCLCC) grading system, this study assesses the accuracy of conventional and modified core biopsy (CB) systems in predicting the final grade (low vs high) assigned to the resected specimen. Substituting Ki-67 immunoexpression for mitotic count, and radiological for histological assessment of necrosis, we used two modified FNCLCC CB grading systems: (1) Ki-67 immunoexpression alone, and (2) Ki-67 plus radiological assessment of necrosis. We graded 199 soft tissue sarcomas (STS) from nine centers, and compared the results for the conventional (obtained from local histopathology reports) and modified CB systems with the final FNCLCC grading of the corresponding resected specimens.

Pulse therapy with vincristine and dexamethasone for childhood acute lymphoblastic leukaemia (CCCG-ALL-2015): an open-label, multicentre, randomised, phase 3, non-inferiority trial.

Lancet Oncol 2021 Jul 27. Epub 2021 Jul 27.

Department of Hematology/Oncology, Shanghai Children's Medical Center, School of Medicine, Shanghai Jiao Tong University, National Health Committee Key Laboratory of Pediatric Hematology & Oncology, Shanghai, China.

Background: Vincristine plus dexamethasone pulses are generally used throughout maintenance treatment for childhood acute lymphoblastic leukaemia. However, previous studies remain inconclusive about the benefit of this maintenance therapy and the absence of randomised, controlled trials in patients with low-risk or high-risk acute lymphoblastic leukaemia provides uncertainty. We therefore aimed to determine if this therapy could be safely omitted beyond 1 year of treatment without leading to an inferior outcome in any risk subgroup of childhood acute lymphoblastic leukaemia.

Wearable Electronics Based on the Gel Thermogalvanic Electrolyte for Self-Powered Human Health Monitoring.

ACS Appl Mater Interfaces 2021 Jul 30. Epub 2021 Jul 30.

Micro Nano System Research Center, College of Information and Computer & Key Lab of Advanced Transducers and Intelligent Control System of the Ministry of Education, Taiyuan University of Technology, Taiyuan 030024, China.

There is always a temperature difference of more than 10 degrees between the human body, as a sustainable heat source, and the ambient temperature. Converting body heat into electricity that in turn is used to drive personal medical electronics is of significance in smart wearable medicine. To avoid the frangibility and complex preparation of traditional thermoelectric materials, we fabricated a gel electrolyte-based thermogalvanic generator with Fe/Fe as a redox pair, which presents not only moderate thermoelectric performance but also excellent flexibility.
