Transcriptomic and epigenomic signatures distinguish high- and low-risk endotypes for liver tumor development.

ABSTRACT: The epigenome is a target for environmental exposures and a potential determinant of inter-individual differences in response. In genetically identical C57Bl/6 mice exposed from gestation to weaning to the endocrine-disrupting chemical (EDC) tributyltin (TBT), hepatic tumor development later in life varied across multiple cohorts over time and depending on sex and diet. In one cohort where approximately half of TBT-exposed male mice developed liver tumors at 10 months (Katz et al. Hepatic tumor formation in adult mice developmentally exposed to organotin, Environmental Health Perspectives, 128 (1), 17010, 2020), transcriptomic (RNA-seq) and epigenomic (ChIP-seq) profiling was performed on blood and liver tissue from mice that developed tumors (i.e., "high-risk") and equivalently exposed mi
