Although it has been well established that overexpression of cyclooxygenase-2 (Cox-2) favors tumorigenesis and metastasis, the molecular mechanism that regulates Cox-2 expression has not been well defined in gastric carcinoma. Aberrant methylation of the CpG island is known to be one of the powerful mechanisms for the suppression of gene expression, and(More)
Epstein-Barr virus is an oncogenic herpesvirus and has been associated with several human malignancies, including gastric cancer. In Epstein-Barr virus-associated gastric cancer, Epstein-Barr virus is found in virtually all tumor cells, but rarely in normal epithelial cells, thus implying that Epstein-Barr virus-targeting therapies are likely to be an(More)
