Systemic administration of Salmonella to tumor-bearing mice leads to preferential accumulation within tumor sites and retardation of tumor growth. However, the detailed mechanism of Salmonella-induced antitumor immune response via host T cell remains uncertain. Herein, we used wild-type, CD4+ T-cell-deficient, and CD8+ T-cell-deficient mice to study the(More)
Angiogenesis plays an important role in the development and progression of tumors. Kallistatin exerts anti-angiogenic and anti-inflammatory activities that may be effective in inhibiting tumor metastasis. We investigated the antitumor effect of lentivirus-mediated kallistatin gene transfer in a syngeneic murine tumor model. Lentiviral vector encoding(More)
Hypoxia, a hallmark of many solid tumors, is associated with angiogenesis and tumor progression. Hypoxia-inducible factor-1 (HIF-1) plays a significant role in tumor angiogenesis. In this study, the authors constructed a selective platform to screen the traditional Chinese medicine as anti-angiogenic agent. The authors examined the molecular mechanism by(More)
In osteoarthritis, angiogenesis, which occurs in the osteochondral junction and synovium, may accelerate inflammation and contribute to the severity of the disease. We used anterior cruciate ligament-transection (ACLT) to investigate the therapeutic effect of an angiogenesis inhibitor, thrombospondin-1 (TSP-1), in a rat model of osteoarthritis.(More)
Despites the fact that T cells are involved in the pathogenesis of osteoarthritis (OA) little is known about the roles of CD8+ T cells in this disease. We investigated the effects of CD8+ T cells and the expression of tissue inhibitor of metalloproteinases 1 (TIMP-1) on joint pathology. Using anterior cruciate ligament-transection (ACLT), OA was induced in(More)
Systemic administration of Salmonella to tumor-bearing mice leads to the preferential accumulation within tumor sites and retardation of the tumor growth. Host factors including innate and adaptive immune responses influence Salmonella-induced antitumor activity. Antitumor activities of Salmonella are not only determined by the tumor regression but also by(More)
Hinokitiol is found in the heartwood of cupressaceous plants and possesses several biological activities. Hinokitiol may play an important role in anti-inflammation and antioxidant processes, making it potentially useful in therapies for inflammatory-mediated disease. Previously, the suppression of tumor growth by hinokitiol has been shown to occur through(More)
In osteoarthritis (OA), inflammation and apoptosis are two important factors contributing to disease progression. As kallistatin can suppress inflammatory responses and reduce cell apoptosis, we investigated the therapeutic effect of kallistatin gene transfer in the rat model of OA by anterior cruciate ligament transection (ACLT). OA was induced in Wistar(More)
Stenosing tenosynovitis of the first dorsal compartment of the wrist (a.k.a. de Quervain's disease) is common but how estrogen is involved is still unknown. We previously reported that inflammation was involved in the pathogenesis of this ailment. In the present study, we extended our investigation of estrogen receptor (ER)-β expression to determine whether(More)
Replication-selective adenovirus has been reported to kill tumor cells and hold promise for cancer therapy. In this study, we constructed an E1B M(r) 55000-deleted adenovirus, designated Ad5WS1, and examined its cytolytic effect on human hepatocellular carcinoma (HCC) cell lines with various p53 status. The results show that Ad5WS1 lysed HCC cells lacking(More)
