Gene Expression Profiling of Infant Embryonal Central Nervous System Tumors by Microarray Gene Chip Analysis: Angiogenesis, Invasion and Metastasis
OBJECTIVES:
- Identify known genes that have significantly different levels of expression, using
microarray gene chip analysis, in infants with newly diagnosed metastatic vs
non-metastatic embryonal central nervous system tumors.
- Determine the protein expression of genes identified by microarray analysis that are
involved in cellular functions that regulate angiogenesis, invasion, or metastasis in
this patient population.
- Determine the quantity of gene expression of the confirmed translationally expressed
genes using semi-quantitative polymerase chain reaction.
OUTLINE: This is a multicenter study.
Tumor samples are analyzed using microarray gene chip analysis. Differentially expressed
genes are evaluated for protein expression by standard immunohistochemistry and/or Western
blot analysis, and gene expression is further quantified by semi-quantitative polymerase
chain reaction.
PROJECTED ACCRUAL: Approximately 80-100 patients (20-25 with metastatic disease and 60-75
with non-metastatic disease) will be accrued for this study within 4-5 years.
