Derivation of Genetically Defined Murine Hepatoblastoma Cell Lines with Angiogenic Potential.

ABSTRACT: Background/Objectives: Hepatoblastoma (HB), the most common pediatric liver cancer, often bears mutations in and/or otherwise deregulates the oncogenic transcription factors β-catenin (B), YAP (Y) and NRF2 (N). HB research is hampered by a paucity of established cell lines, particularly those possessing these molecular drivers. All combinations of B, Y and N (BY, BN, YN and BYN) are tumorigenic when overexpressed in murine livers, but it has not been possible to establish cell lines from primary tumors. Recently, we found that concurrent, in vivo Crispr-mediated targeting of the Cdkn2a tumor suppressor locus allows for immortalized cell lines to be efficiently generated. Methods: We derived and characterized five immortalized cell lines from Cdkn2a-targeted BN a
