Similarly, combined analysis of the 165 ROS-associated genes with the 3352 downregulated DEGs revealed 22 candidate ROS-associated downregulated DEGs in COAD, including LRPK2, TLR6, CYBB, ATP7A, HIF1A, CD36, CYP1B1, P2RX7, NOX4, TLR2, SH3PXD2A, BCL2, AGTR1, FBLN5, PDK4, THBS1, ITGAM, PDGFRB, EDN1, LEP, SFTPD, and MAPT. This evidence concerns the gene LEP and colon adenocarcinoma.
