GSEA enrichment analysis of the single gene ITGA11 in IAs revealed the following pathways: multispecies apoptosis, biosynthesis of nucleotide sugars, glycosaminoglycan biosynthesis (chondroitin sulfate/dermatan sulfate), p53 signaling pathway, and small cell lung cancer (Fig. 11A). Here, ITGA11 is linked to small cell lung carcinoma.
