Kim analyzed the differential expression of genes between normal pancreas tissues and PAAD tissues using LASSO regression analysis to construct the prognostic gene expression model, which revealed LAMA3, E2F7, IFI44, SLC12A2, and LRIG1 as the potential drug targets in PAAD treatment (Kim et al. 2019). Here, E2F7 is linked to pancreatic adenocarcinoma.
