GATA6 and pancreatic ductal adenocarcinoma: Mishra et al.s’ study represents the first TCGA-based PDAC methylome data analysis and first reported that several genes (B3GNT3, DMBT1, and DEPDC1B) and lncRNAs (PVT1, and GATA6-AS) are strongly correlated with pancreatic ductal adenocarcinoma survival (Kumar Mishra et al., 2019).
