High expression of TSPOAP1-AS1 has been associated with a better prognosis in patients with pancreatic ductal adenocarcinoma (Giulietti et al., 2018), consistent with the results in LUAD, while TSPOAP1-AS1 showed significantly higher methylation levels in pancreatic ductal adenocarcinoma compared with normal samples. Here, TSPOAP1 is linked to pancreatic ductal adenocarcinoma.
