A Nature Genetics study published October 13 maps how genetically distinct cell populations coexist within pancreatic ductal adenocarcinoma. Researchers analyzed 443,451 individual cells from 62 primary tumors, adding spatial measurements for 11 tumors and matched samples before and after chemotherapy for six.
The analysis found that different tumor clones had distinct gene-activity patterns and interactions with surrounding cells. Gains or losses of genes involved in cellular communication were linked to differences in those interactions.
Amplification of the MYC region was repeatedly associated with transitions from a classical to a basal tumor state, accompanied by weaker immune-response programs. In mouse and primary human experimental models, reducing MYC activity restored classical gene-expression patterns and immune-related pathways.
Spatial analyses also identified dispersed clones with features associated with invasion, immune suppression and metastatic potential.
The study provides a resource for investigating tumor evolution and treatment resistance. However, the large cell count should not be mistaken for a large patient trial. The findings combine tumor profiling with laboratory experiments; they do not show that a MYC-targeted treatment improves survival in patients.
