Study of the gene expression and microRNA expression profiles of malignant rhabdoid tumors originated in the brain (AT/RT) and in the kidney (RTK)

Purpose Malignant rhabdoid tumors (MRT) can occur in a variety of anatomical sites. The most frequent locations are the brain, where they are named atypical teratoid/rhabdoid tumors (AT/RT), and the kidney, where they are named rhabdoid tumors of the kidney (RTK). MRTs at all sites are recognized as the same entity due to their similar morphology, aggressive behavior, and a common genetic abnormality, an inactivating mutation of the SMARCB1/INI-1/hSNF5/BAF47 gene. We aim to investigate potential molecular differences between AT/RT and RTK.
