In consistence, all the differential genes verified among 32 tissues have statistical differences (P < 0.001), reconfirming the reliability of gene expression microarrays.As shown in Table 2, among these 15 differential genes, RACK1, ARHGDIB, STMN1, LGALS7, EIF5A, and TAGLN were significantly overexpressed in OSCC tumor compared with non-tumor. Here, EIF5A is linked to neoplasm.
