Intended Use
MYCN expression is associated with the maintenance of self-renewal capacity and the pluripotent status of stem cells. Dysregulation of MYCN contributes to the development of different kinds of childhood tumors including neuroblastoma, medulloblastoma, rhabdomyosarcoma and Wilms tumor. MYCN is also involved in the development of some adulthood neoplasms such as prostate and lung cancer.
Patient Preparation
- Sample collection: Tumour Tissue Block
