Genetics and Biology of Liver Tumorigenesis in Children
OBJECTIVES:
Primary
- To identify biomarker signatures associated with hepatoblastoma subtypes (by microRNA
array profiling), and their potential correlation with liver developmental stages as
well as outcome.
- To correlate expression array data with copy number array data.
Secondary
- To carry out a focused sequencing interrogation of amplified or deleted genomic regions
as well as genes in key cell pathways involved in embryonic development and/or stem
cell signaling pathways for which preliminary data suggests involvement in the
pathogenesis of hepatoblastoma.
- To perform whole exome sequencing in a subset of tumors.
OUTLINE: This is a multicenter study.
Archived tumor tissue samples are analyzed for hepatoblastoma and other liver tumor
biomarkers by microRNA array profiling and exome sequencing. Results are then compared with
patients' clinical data.
