Expression profiling of primitive neuroectodermal tumours
Measurement Type: 
Transcription Profiling (Microarray)
Design Type: 
Cross Sectional Design
Primitive neuro-ectodermal tumours (PNET) of the supratentorial region are rare, highly malignant embryonal brain tumours affecting young children. Although supratentorial PNET (sPNET) are histologically similar to infratentorial PNET/medulloblastoma, sPNET have more aggressive clinical phenotypes, which suggest sPNET represents distinct biological entities. In contrast to considerable progress in understanding the signalling pathways involved in medulloblastoma, little is known about sPNET pathogenesis. We utilized the Illumina Human-6 v2 Expression BeadChip platform to define pathways dysregulated in sPNET pathogenesis.
