The study also identified specific lung cancer protein biomarkers not present in healthy animals, including ADAMTS12, abnormal spindle, adducin 3, aGPCRs, agrin, ACIN1, BRAF, hypoxia-induced gene-1, LRRC2, LRRK2, LRCH2, MSS4A, proto-oncogene tyrosine-protein kinase Src, RAB14, SCCA, TIF1α, and BRCA2. This evidence concerns the gene AGRN and lung carcinoma.
