| Research Abstract |
Chronic inflammation induced by biological, chemical, and physical factors has been found to be associated with the increased risk of cancer. We revealed that the nuclear localization of COX-2, which was reported to function as a transcription factor, was significantly associated with the up-regulation of stem cell marker in cancer tissues with parasite infection. COX-2 activation may be involved in stem cell proliferation/differentiation in inflammation-mediated carcinogenesis. 8-Nitroguanine was formed in stem cell marker-positive cells in inflammation-associated cancer tissues. Inflammation may increase the number of mutant stem cells, in which iNOS-dependent DNA damage occurs via NF-κB activation, leading to tumor development.
