For example, Chen et al. [37] found that the mRNA and protein expression of CPEB4 was upregulated in astrocytic tumour tissues, and the results of Xu et al. [38] showed that CPEB4 was lowly expressed in pancreatic ductal adenocarcinoma, intraductal papillary mucinous adenoma, and intraductal papillary mucinous carcinoma. The gene discussed is CPEB4; the disease is pancreatic ductal adenocarcinoma.
