BACKGROUND Neuroblastoma remains a major cause of cancer-linked mortality in children. miR-204 has been used in microRNA expression signatures predictive of neuroblastoma patient survival. The aim of this study was to explore the independent association of miR-204 with survival in a neuroblastoma cohort, and to investigate the phenotypic effects mediated by(More)
Neuroblastoma is responsible for 15% of all childhood cancer deaths. Despite advances in treatment and disease management, the overall 5-year survival rates remain poor in high-risk disease (25-40%). MiR-497 was previously identified by our laboratory as a member of a miRNA expression signature, predictive of neuroblastoma patient survival and has been(More)
MiRNAs can have pleiotropic effects by targeting multiple genes belonging to diverse signalling networks. Alternatively, miRNAs can enhance the potency of their cellular effects by targeting multiple genes within the same genetic pathway. Previously, we and others have demonstrated that miR-335 is a potent suppressor of tumour cell migration, invasion and(More)
Protein tyrosine phosphatase receptor delta (PTPRD) is a member of a large family of protein tyrosine phosphatases which negatively regulate tyrosine phosphorylation. Neuroblastoma is a major childhood cancer arising from precursor cells of the sympathetic nervous system which is known to acquire deletions and alterations in the expression patterns of(More)
Ultra-conserved regions (UCRs) are segments of the genome (≥ 200 bp) that exhibit 100% DNA sequence conservation between human, mouse and rat. Transcribed UCRs (T-UCRs) have been shown to be differentially expressed in cancers versus normal tissue, indicating a possible role in carcinogenesis. All-trans-retinoic acid (ATRA) causes some neuroblastoma (NB)(More)
Chronic lymphocytic leukaemia (CLL) represents the most common leukaemia in the western world. The cytogenetic analysis for specific karyotypic events plays an important part in the diagnostic work up of these patients. The most frequently described aberration in CLL, in about 50% of cases, are deletions of chromosome 13q. Since 2005, 313 patients at(More)
Dysbindin is known to (a) bind ß-dystrobrevin in postsynaptic densities in a number of brain areas, and (b) be a component of the biogenesis of lysosome-related organelles complex 1 (BLOC-1). Reduced levels of dysbindin have been identified presynaptically at hippocampal formation sites lacking ß-dystrobrevin in schizophrenia cases. This suggests a role for(More)
