However, pretreatment with FPR1 antagonists cyclosporin H or tBoc-MLF reduced the response of HepG2 and Hep3B cells induced by fMLF (Fig.?S4D-I). production of angiogenic factor IL-8 by human gliobstoma.7,17 FPR1 in glioblastoma cells also interacts with agonists released by necrotic tumor cells, 7 suggesting that tumor cells may utilize FPR1 to recognize agonists produced in the tumor microenviroment for their advantage. Since hepatocarcinogenesis involves a highly orchestrated interplay of injury, chronic inflammation and neovascularization, 2 the multitude NMS-P515 of FPR1 suggests that it may also play a role in the development of hepatic cancer.5-7, Gusb 9,17 In the present study, we report that FPR1 was expressed by HCC tissues from patients and the human hepatoma cell lines. Hepatoma cells responded to the FPR1 agonist fMLF by increased motility, proliferation and enhanced IL-8 production. FPR1 small hairpin RNA (shRNA) substantially reduced the tumorigenicity of hepatoma cells in nude mice. Our study…
