Abstract
Pancreatic ductal adenocarcinoma (PDAC) remains one of the most devastating human diseases. There is consequently a pressing need to understand its molecular underpinnings, which should enable new preventive and therapeutic strategies. A new study in The EMBO Journal (Diaferia et al, 2016) maps the transcriptome and epigenetic landscape associated with distinct PDAC grades and identifies cis‐ and trans‐regulatory elements in tumour progression.
