Genetic and Epigenetic Basis of Hepatoblastoma Diversity

Scientists performed an integrative genomic profiling of 163 pediatric liver tumors based on the data acquired from a cohort study. DNA methylation profiling revealed that classical hepatoblastomas were characterized by the specific hypomethylated enhancers, which were enriched with binding sites for ASCL2, a regulatory transcription factor for definitive endoderm in Wnt-pathway.
