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 transformed with a lambdaZAPII 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 myomegalin (MMGL, phosphodiesterase 4D interacting protein/PDE4DIP) as a new SEREX antigen for esophageal SCC. Western blot analysis revealed that serum anti-myomegalin antibodies (s-MMGL-Abs) were present in 43 (47%) of 91 patients, but in only one (2.2%) of 45 healthy controls. Of the 21 patients with stage I disease, 8 (38%) were sero-positive. The positive rate of s-MMGL-Abs was greater than those of other conventional tumor markers. Reverse transcription-PCR analysis suggested that alternative splicing from myomegalin variant 1 to variant 5 may explain, in part, the development of s-MMGL-Abs. Although the presence of s-MMGL-Abs was not related to any clinicopathological features of the patients, multivariate analysis indicated that the presence of s-MMGL-Abs was significantly associated with a favorable prognosis. Consequently, s-MMGL-Abs may be a useful tumor marker to diagnose and establish a prognosis in patients with esophageal SCC.
