The mRNA expression levels of 10 DEGs (Serpinc1, Has1, Nrn1, Lrrc2, Tdrd6, Erp27, Fcrls, Fam107a, Chst3, Cd1d2) in tumor tissues by qRT-PCR were consistent with our transcriptomic analysis, while the expression levels of seven DEGs (Apela, Prg4, Gldc, Cntnap5a, Fbxo15, Ccdc3, Hs3st6) were opposite with transcriptomic analysis (Figures 5D, S3, data not shown partially). Here, PRG4 is linked to neoplasm.
