A microRNA-1280/JAG2 network comprises a novel biological target in high-risk medulloblastoma
Over-expression of PDGF receptors (PDGFRs) has been previously implicated in high-risk medulloblastoma (MB) pathogenesis. However, the exact biological functions of PDGFRα and PDGFRβ signaling in MB biology remain poorly understood. Here, we report the subgroup specific expression of PDGFRα and PDGFRβ and their associated biological pathways in MB tumors. c-MYC, a downstream target of PDGFRβ bu...
متن کاملIGF1R as a Key Target in High Risk, Metastatic Medulloblastoma
Risk or presence of metastasis in medulloblastoma causes substantial treatment-related morbidity and overall mortality. Through the comparison of cytokines and growth factors in the cerebrospinal fluid (CSF) of metastatic medulloblastoma patients with factors also in conditioned media of metastatic MYC amplified medulloblastoma or leptomeningeal cells, we were led to explore the bioactivity of ...
متن کاملMedulloblastoma comprises four distinct molecular variants.
PURPOSE Recent genomic approaches have suggested the existence of multiple distinct subtypes of medulloblastoma. We studied a large cohort of medulloblastomas to determine how many subgroups of the disease exist, how they differ, and the extent of overlap between subgroups. METHODS We determined gene expression profiles and DNA copy number aberrations for 103 primary medulloblastomas. Bioinfo...
متن کاملMELK is a novel therapeutic target in high-risk neuroblastoma
Maternal embryonic leucine zipper kinase (MELK) is known to modulate intracellular signaling and control cellular processes. However, the role of MELK in oncogenesis is not well defined. In this study, using two microarray datasets of neuroblastoma (NB) patients, we identified that MELK expression is significantly correlated to poor overall survival, unfavorable prognosis, and high-risk status....
متن کاملPre-irradiation chemotherapy in high risk medulloblastoma.
RATIONALE The present study evaluates the effect of pre-irradiation chemotherapy in pediatric patients with high risk medulloblastoma. Twenty-four (24) pediatric patients attended the pediatric unit of Kasr-El-Aini Center of Radiation Oncology and Nuclear Medicine (NEMROCK) from January 2000 to January 2003. PATIENTS AND METHODS Our patients were 13 boys and 11 girls aged 3-12 years with a me...
