Altered chromosomal topology drives oncogenic programs in SDH-deficient GISTs
Gastrointestinal stromal tumours can be initiated by gain-of-function mutations of the KIT or PDGFRA oncogenes but also by loss of the metabolic complex succinate dehydrogenase (SDH), which leads to DNA hypermethylation; this study shows that in SDH-deficient tumours, displacement of CTCF insulators by DNA methylation activates oncogene expression, illustrating how epigenetic alterations can drive oncogenic signalling in the absence of kinase mutations.
