Abstract Somatic mutations in cytosolic or mitochondrial isoforms of isocitrate dehydrogenase (IDH1 IDH2, respectively) contribute to oncogenesis via production the metabolite 2-hydroxyglutarate (2HG). Isoform-selective IDH inhibitors suppress 2HG and induce clinical responses patients with IDH1- IDH2-mutant malignancies. Despite promising activity inhibitors, mechanisms that mediate resistance inhibition are poorly understood. Here, we describe four cases identify mutant isoform switching,...

Hec1 (Highly Expressed in Cancer 1) is one of four proteins the outer kinetochore Ndc80 complex involved dynamic interface between centromeres and spindle microtubules. Its overexpression seen a variety human tumors correlates with tumor grade prognosis. We show here that an inducible mouse model results mitotic checkpoint hyperactivation. As previously observed Mad2 gene, hyperactivation leads to aneuploidy vitro sufficient generate vivo harbor significant levels aneuploidy. These...

Polyamines are polycationic alkyl-amines abundant in proliferating stem and cancer cells. How these metabolites influence numerous cellular functions remains unclear. Here we show that polyamine levels decrease during differentiation inhibiting synthesis leads to a differentiated-like cell state. concentrate the nucleus further enriched nucleoli of cells culture

Oncogenic IDH1/2 mutations produce 2-hydroxyglutarate (2HG), resulting in competitive inhibition of DNA and protein demethylation. IDH-mutant cancer cells show an inability to differentiate but whether 2HG accumulation is sufficient perturb differentiation directed by lineage-specifying transcription factors unknown. A MyoD-driven model was used study the role IDH mesenchymal cells. The presence produced oncogenic IDH2 blocks ability MyoD drive into myotubes. 5mC hypermethylation dispensable...

<h3>Importance</h3> Predicting outcomes in patients receiving neoadjuvant therapy for rectal cancer is challenging because of tumor downstaging. Validated clinical calculators that can estimate recurrence-free survival (RFS) and overall (OS) among with who have received multimodal are needed. <h3>Objective</h3> To develop validate providing estimates recurrence better individualized decision-making than the American Joint Committee on Cancer (AJCC) staging system or (NAR) score. <h3>Design,...

Summary Oncogenic mutations in the metabolic enzyme isocitrate dehydrogenase 1 and 2 (IDH1/2) have been found a number of liquid solid tumors. Their pathogenic mechanism action involves production 2-hydroxyglutarate (2HG), an oncometabolite that acts part by inhibiting members family dioxygenases modulate chromatin dynamics. Recent work has suggested mutant IDH (mIDH) 2HG also impact sensitivity to inhibitors poly-ADP ribose polymerases (PARP) but molecular basis for this is unclear. Unlike...

Abstract Poor differentiation (the divergence of tumor cell morphology from the cellular normal tissue origin) is associated with unfavorable responses to chemotherapy and poor clinical outcomes in solid tumors. Recurrent somatic mutations genes encoding for metabolic enzymes isocitrate dehydrogenase (IDH) 1 2 have recently been identified patients acute myeloid leukemias, chrondrosarcomas, cholangiocarcinomas glioblastomas. Point IDH lead production 2-hydroxyglutarate (2HG). 2HG acts as a...
