This paper deals with e-tourism, innovation and growth. The Internet is revolutionising the distribution of tourism information and sales. The Korean small and medium-sized tourism enterprises (SMTEs) with well-developed and innovative Web sites can now have " equal Internet access " to international tourism markets. This paper examines problems and(More)
Patrinia scabiosaefolia (PS) has been used for curing various types of inflammatory-related disorders. However, the precise mechanism of the anti-inflammatory activity of PS remains unclear. Here, we investigated the anti-inflammatory effects of several fractions isolated from the PS in RAW 264.7 macrophages. The results indicated that the ethyl acetate(More)
Emodin (ED), an anthraquinone derivative, has been found to inhibit proliferation, induce apoptosis, suppress angiogenesis, impede metastasis, and enhance chemotherapy. However, the detailed mechanism of ED related to the regulation of CXC chemokine receptor-4 (CXCR4) gene expression that affects cellular migration and invasion in prostate and lung cancer(More)
Persistent STAT3 activation is seen in many tumor cells and promotes malignant transformation. Here, we investigated whether capsazepine (Capz), a synthetic analogue of capsaicin, exerts anticancer effects by inhibiting STAT3 activation in prostate cancer cells. Capz inhibited both constitutive and induced STAT3 activation in human prostate carcinoma cells.(More)
AIMS Prostate cancer (PCa) is one of the most commonly diagnosed cancers worldwide. Currently available therapies for metastatic PCa are only marginally effective, hence novel treatment modalities are urgently required. Considerable evidence(s) suggest that deregulated activation of oncogenic transcription factor, signal transducer and activator of(More)
The aerial parts of Artemisia capillaris (Compositae) have been used in traditional Korean medicine as a cholagogic, antipyretic, anti-inflammatory, and diuretic purposes. In our previous study, ethanolic extracts of the plant demonstrated a marked anti-inflammatory effect in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells (J. Korean Soc. Appl. Biol.(More)
Persistent phosphorylation of signal transducers and activators of transcription 3 (STAT3) is frequently observed in tumor cells. We found that brassinin (BSN) suppressed both constitutive and IL-6-inducible STAT3 activation in lung cancer cells. Moreover, BSN induced PIAS-3 protein and mRNA, whereas the expression of SOCS-3 was reduced. Knockdown of PIAS-3(More)
Chrysanthemum indicum L. has been shown to possess antiinflammatory and anticancer activities, but its molecular targets/pathways are not yet fully understood in tumor cells. In the present study, the potential effects of C. indicum on signal transducer and activator of transcription 3 (STAT3) signaling pathway in different tumor cells were examined. The(More)
We have recently reported that β-caryophyllene oxide (CPO) can induce apoptosis, suppress tumor growth, and inhibit metastasis through the suppression of signal transducer and activator of transcription 3, PI3K/AKT/mTOR/S6K1 signaling cascades and ROS-mediated MAPKs activation. In the present study, we found that CPO potentiated the apoptosis induced by(More)
OBJECTIVES Signal transducer and activator of transcription 3 (STAT3) is an oncogenic transcription factor implicated in carcinogenesis. Here, we investigated the role of morusin, the major prenylflavonoid, isolated from Chinese herbal medicine in abrogating the constitutive STAT3 activation in human pancreatic tumor cells. METHODS The effect of morusin(More)
