Cancer epigenetics is the study of somatically heritable changes to molecular processes that influence the flow of information between the DNA of cancer cells and their gene expression patterns. This includes comparative (tumour cell versus normal cell) investigation of nuclear organization, DNA methylation, histone modification and the consequences of genetic mutations in genes encoding epigenetic regulators.
Hepatoblastoma (HB) is the most frequent paediatric liver tumour with heterogeneous cellular phenotypes that influence clinical outcomes. Here, the authors integrate bulk, single-cell, and spatial multi-omics to characterise HB cells, and find that clonal evolution and epigenetic plasticity shape response to therapy.
In a recent Developmental Cell paper, Falvo et al. establish a role for epigenetic memory of inflammatory injury in promoting pancreatic tumorigenesis.
Rahme et al. establish an in vivo model for low-grade glioma, and use it to demonstrate that Pdgfra insulator loss and Cdkn2a promoter silencing are epigenetic drivers of gliomagenesis.
