Background: The pathogenesis of neural crest-derived tumours (phaeochromocytoma and neuroblastoma) is complex, and several studies applying functional genomics approaches have been performed in these tumours to date. However, the comparison of their genomic features has not been performed yet.Objective: We have carried out an in silico meta-analysis of altogether 1784 neuroblastoma and 351 phaeochromocytoma samples to establish similarities and differenc...

Background: The adrenolytic agent mitotane is widely used in the adjuvant treatment of adrenocortical cancer, but its mechanism of action including potential effects on mRNA expression is poorly elucidated.Objective: To examine mitotane-induced mRNA expression changes in the H295R adrenocortical cancer cell line.Methods: Various concentrations of mitotane in different treatment periods (24–120 h) have been tested in cell viabi...

Background: The differential expression of tissue microRNAs in benign and malignant adrenocortical tumours has been described in several studies including ours. Novel data show that microRNAs are also present in the bloodstream and can be exploited as minimally invasive markers of malignancy.Objective: To analyze the microRNAs expressed in different studies by an in silico approach and to establish the molecular pathways affected. Furthermore, circulatin...
