| Outline of Final Research Achievements |
In the pilot study, microarray analysis indicated the possibility of SERPINB7 over expression as a biomarker for the risk of EAC in the previous case control study investigating brushing samples taken from targeted BE mucosa of USA patients by endoscopy. The validation study group consisted of 12 EAC patients (LSBE 2,) and 65 sex and age-matched patients with BE patients(LSBE 11, SSBE 54). The expression levels of TRHDE, PDZK1,SERPINB7 were higher and SCNN1B was significantly lower in the LSBE control group than those in the SSBE group. The expression levels of SCNN1B was lower, and SERPINB7 was higher in the BE of the EAC groups than those in the SSBE of the controls among the 3 groups. Overexpression of SERPINB7 and down-expression of SCNN1B in the LSBE patient were recognized in Japanese patients as well as USA patients. SCNN1B may be useful markers to select patients for surveillance for LSBE and EAC.
