From: IMUP and GPRC5A: two newly identified risk score indicators in pancreatic ductal adenocarcinoma
The differently expressed genes in PAAD vs normal pancreatic tissues identified from multiple GEO datasets. From GEO datasets A GSE15471, B GSE16515, C GSE413687, D GSE43795 and E GSE71989, the up-regulated (right-sided) and down-regulated (left sided) differently expressed genes in PAAD comparing to normal pancreatic tissues were identified. And the genes were then classified into four groups based on difference level as: < twofold genes (orange-colored spots in A–E), 2 ~ fourfold genes (red-colored spots in A-E), 4 ~ eightfold genes (green-colored spots in A–E) and > eightfold genes (black-colored spots in A–E).
