Higher expression levels in tumour relative to non-tumour tissue of > tenfold were found for CgA, 2—tenfold higher mRNA levels were found for CD56, β-catenin, PDX1, CK20, and P53 and 1—twofold higher mRNA levels were found in CD45 tumour tissue compared with the non-tumour tissue. The gene discussed is TP53; the disease is neoplasm.
