Lipase member H frequently overexpressed in human esophageal adenocarcinomas.

Esophageal cancer is one of the most frequent causes of cancer-related deaths worldwide. This is due to its asymptomatic nature or mild nonspecific symptoms. Most patients are diagnosed after appearance of prominent symptoms, and tumors are frequently accompanied by severe infiltration. Therefore, molecular biomarkers for the prognosis of early-stage esophageal cancer are desired. In this study, we examined the prognostic potential of lipase H (LIPH), a recently reported biomarker for lung adenocarcinoma and squamous carcinoma. We found that LIPH mRNA is also frequently upregulated in esophageal adenocarcinoma. Immunohistochemical analysis confirmed LIPH protein expression in various esophageal tumor tissue sections. Interestingly, higher expression of LIPH in esophageal adenocarcinoma showed a positive correlation with longer survival of patients. Our data suggest that LIPH may have prognostic value for esophageal cancer.
