Research Abstract

In order to identify new serum markers of esophageal squamous cell carcinoma (SCC), we performed serological identification of antigens by recombinant cDNA expression cloning (SEREX). E.coli was infected with λZAPII phage cDNA library prepared from mRNA of an esophageal cancer cell line (T.Tn), and IPTG-induced cDNA products were screened for interaction with antibodies in allogeneic sera of patients with esophageal SCC. We identified TROP-2, GLUT-1/SLC2A1, TRIM21, myomegalin, as new SEREX antigens for esophageal SCC. Western blotting analysis revealed that serum anti-antibodies for these SEREX antigens were present in 20 to 47% of patients but not in healthy controls. Although the presence of serum SEREX-Abs were not related to any of clinicopathological features of the patients concerned, multivariate analysis indicated that presence of s-myomegalin-Abs was significantly associated with favorable prognosis. Moreover, s-TROP-2-Abs was associated with tumor size. Because there serum antibodies against SEREX antigens were not associated with other conventional tumor markers, there serum markers were useful as a new tumor markers for esophageal SCC.
