Differential expression analysis of these 27 intersecting genes in the GSE87211 dataset from GEO revealed significant expression differences between tumor and normal groups for 26 genes, with ASCL2, IFITM3, IFITM1, SMPDL3A, and SUCLG2 being the five most significantly differentially expressed (Figure 2C). This evidence concerns the gene IFITM1 and neoplasm.
