In tumour tissue, CgA and NSE mRNA levels were significantly greater than DAXX while synaptophysin, CD56, Ki67, PCNA, CD44, CD31, CD45, vimentin, β-catenin, MENA, CD49, laminin, ECAD, PCAD, EPCAM, CDX2, PDX1, CD14, CK7, CK13, CK20 and p53 had mRNA levels that were significantly lower than DAXX (Fig. 1c). This evidence concerns the gene ENO2 and neoplasm.
