Wilms tumour is the most common childhood kidney cancer. Here we report the whole-exome sequencing of 44 Wilms tumours, identifying missense mutations in the microRNA (miRNA)-processing enzymes DROSHA and DICER1, and novel mutations in MYCN, SMARCA4 and ARID1A. Examination of tumour miRNA expression, in vitro processing assays and genomic editing in human(More)
BACKGROUND Previous studies in mice showed that respiratory syncytial virus (RSV) infection was associated with RSV RNA persistence. This study was designed to characterize the significance of RSV RNA persistence and its relation to RSV-induced chronic airway disease. METHODS Mice were inoculated with live RSV, UV light-treated RSV, heat-inactivated RSV,(More)
BACKGROUND Respiratory Syncytial Virus (RSV) infection is usually restricted to the respiratory epithelium. Few studies have documented the presence of RSV in the systemic circulation, however there is no consistent information whether virus detection in the blood correlates with disease severity. METHODS Balb/c mice were inoculated with live RSV,(More)
In Wilms tumor (WT), mutations in the gene encoding p53, TP53, are correlated with anaplasia; however TP53 variants have not been studied in favorable histology (FH) WTs. A single nucleotide polymorphism of TP53 encoding either arginine or proline at codon 72 is suggested to alter in vitro p53 behavior. Therefore, we analyzed tissue from 23 consecutive(More)
Elevated levels of d-2-hydroxyglutarate (d-2-HG) occur in gliomas and myeloid leukemias associated with mutations of IDH1 and IDH2. l-2-Hydroxyglutaric aciduria, an inherited metabolic disorder, predisposes to brain tumors. Therefore, we asked whether sporadic cancers, without IDH1 or IDH2 hot-spot mutations, show elevated 2-hydroxyglutarate levels. We(More)
BACKGROUND The aim of the study was to assess the performance of Promega, Maxwell® 16 for the extraction of genomic DNA from whole blood and FFPE tissue. METHODS DNA was extracted from 10 whole blood and 10 FFPE specimens using six different commercial kits. RESULTS For whole blood, the mean DNA concentration obtained by Maxwell® 16 was significantly(More)
Reprogramming of energy metabolism, such as increased glycolysis, is a hallmark of cancer cells. One mechanism by which cancer cells fuel glycolysis is through increased uptake of glucose across cell membranes via the glucose transporter GLUT1. One of the transcriptional repressors of GLUT1 is wild-type TP53, and cancer-associated loss of function mutations(More)
