SLC35A2 and pancreatic adenocarcinoma: CNV and SLC35A2 expression were negatively correlated in five cancers, such as pancreatic adenocarcinoma (PAAD) (considered significant when FDR ≤ 0.05), suggesting that SLC35A2 expression was primarily regulated by other factors such as the activation of transcription in these cancers (Figure 1D).
