Key genes in this cluster include LAPTM5, IRF1, TAP1, GBP4, C1QB, GPNMB, ICAM1, APOE, GM2A, TNFSF10, C1QC, TYMP, GBP5, and IDO1. The white cluster highlights downregulated genes in EBV+ GC samples, with notable genes including FAM3B, CAMK2N1, LIMCH1, SARM1, RAP1GAP, and UBXN10. This evidence concerns the gene C1QB and gastric cancer.
