MetabolomicsTissue metabolites in diffuse glioma and their modulations by IDH1 mutation, histology, and treatment
The discovery of the oncometabolite 2-hydroxyglutarate in isocitrate dehydrogenase 1-mutated (IDH1-mutated) tumor entities affirmed the role of metabolism in cancer. However, large databases with tissue metabolites that are modulated by IDH1 mutation remain an area of development. Here, we present a...

MetabolomicsCell of origin epigenetic priming determines susceptibility to Tet2 mutation

Hematopoietic stem cell (HSC) mutations can result in clonal hematopoiesis (CH) with heterogeneous clinical outcomes. Here, we investigated how the cell state preceding Tet2 mutation impacts the pre-malignant phenotype. Using an inducible system for clonal analysis of myeloid progenitors...

MetabolomicsMetabolic alterations caused by the mutation and overexpression of the Tmem135 gene
Mitochondria are highly dynamic organelles undergoing fusion, fission and degradation. Although mitochondria are known to be essential for cellular metabolism, it is not fully understood how mitochondrial dynamics affect cellular metabolism. We previously identified a mouse gene, transmembrane prote...

MetabolomicsA single gene mutation underpins metabolic adaptation and acquisition of filamentous competence in the emerging fungal pathogen Candida auris

Filamentous cell growth is a vital property of fungal pathogens. The mechanisms of filamentation in the emerging multidrug-resistant fungal pathogen Candida auris are poorly understood. Here, we show that exposure of C. auris to glycerol triggers a rod-like filamentation-competent (RL-FC) phenoty...

MetabolomicsReactive Oxygen Species Deficiency Due to Ncf1-Mutation Leads to Development of Adenocarcinoma and Metabolomic and Lipidomic Remodeling in a New Mouse Model of Dextran Sulfate Sodium-Induced Colitis
Inflammatory bowel disease is characterized by chronic relapsing idiopathic inflammation of the gastrointestinal tract and persistent inflammation. Studies focusing on the immune-regulatory function of reactive oxygen species (ROS) are still largely missing. In this study, we analyzed an ROS-deficie...

TranscriptomicsMutation Order Affects Tumor Evolution and Clinical Course of Disease
Background: Cancers result from accumulation of somatic mutations and their properties are thought to reflect the sum of these mutations. However, little is known about the consequences of altering the order of mutation acquisition. Methods: Mutation order was determined in myeloproliferative neopl...

TranscriptomicsIdentification of differentially expressed genes between clinical and bovine-biased Escherichia coli O157:H7 genotypes
Escherichia coli O157:H7 strains have been classified into different genotypes based on the presence of specific shiga toxin-encoding bacteriophage insertion sites. Genotypes that are predominant in clinical isolates are named clinical genotypes and those that are isolated mostly from bovine source...

ModelsSun2018 - Instantaneous mutation rate in cancer initiation and progression
Background Cancer is one of the leading causes for the morbidity and mortality worldwide. Although substantial studies have been conducted theoretically and experimentally in recent years, it is still a challenge to explore the mechanisms of cancer initiation and progression. The investigation for ...

TranscriptomicsBRAF Mutation Is Rare in Advanced-Stage Low-Grade Ovarian Serous Carcinomas
Low-grade ovarian serous carcinomas are believed to arise via an adenoma-serous borderline tumor-serous carcinoma sequence. In this study, we found that advanced-stage, low-grade ovarian serous carcinomas both with and without adjacent serous borderline tumor shared similar regions of loss of hetero...
