The team used techniques called single-cell sequencing and spatial transcriptomics to study the regulation of infiltrating glioblastoma cells. By analyzing which genes were active, chemical modifications to the DNA, how open or closed different regions of DNA were, and how tumour cells physically and molecularly interacted with nearby neurons, they identified key developmental pathways that invasive glioblastoma cells hijack to spread through the brain.One such pathway is called NOTCH signaling – a cell communication system used by multicellular organisms to control cell fate decisions, such as differentiation, proliferation and apoptosis. The tumour cells hijack this pathway to activate oligodendrocyte lineage programs, effectively masquerading as normal OPCs.The findings suggest that targeting this pathway and the regulatory programs involved may help limit tumour spread.
