Tanshinone IIA (Tan IIA) is one of the major lipophilic components of Salvia miltiorrhiza Bunge reported to exhibit anti-carcinogenic effect. In the present study, we further evaluated the anti-angiogenic effect of Tan IIA using the chorioallantoic membrane (CAM) in chicken embryos and human umbilical vascular endothelial cells (HUVECs). Tan IIA was(More)
Naringin has been reported to have an anti-atherosclerosis effect but the underlying mechanism is not fully understood. The aim of this study is to investigate the impact of naringin on the TNF-α-induced expressions of cell adhesion molecules, chemokines and NF-κB signaling pathway in human umbilical vein endothelial cells (HUVECs). The experiments revealed(More)
OBJECTIVE We hypothesized a possible mechanism for atherosclerosis in which interleukin-6 (IL-6) might affect the endothelial nitric oxide synthase (eNOS)-caveolin-1 interaction and result in decreased nitric oxide bioavailability in the setting of low-grade inflammation. METHODS Because eNOS and caveolin-1 are crucial for vascular tone control, we(More)
A variety of studies have suggested a cancer protective role of cruciferous vegetables. In the present study, we investigated the effect of indole-3-carbinol (I3C), a major indole metabolite in cruciferous vegetables, on cell proliferation and in vitro markers of angiogenesis in phorbol myristate acetate (PMA)-stimulated endothelial EA hy926 cells. The(More)
Crude extract of Scutellaria baicalensis (S. baicalensis) has cytotoxic effect on human myelogenous leukemia cells (HL-60). We invesigated which compound from the crude extract is responsible for the cytotoxic effect on HL-60 cells. We identified 29 compounds from the crude extract using high performance liquid chromatography mass spectrometry (HPLC/MS).(More)
Tanshinone IIA is one of the major diterpenes in Salvia miltiorrhiza. The inhibitory effect of Tanshinone IIA on atherosclerosis has been reported, but the underlying mechanism is not fully understood. The present study aimed to study the anti-atherosclerosis effect of Tanshinone IIA on the adhesion of monocytes to vascular endothelial cells and related(More)
This study aimed to assess the potential anti-angiogenic mechanism of Phyllanthus urinaria (P. urinaria) and characterize the major compound in P. urinaria that exerts anti-angiogenic effect. The water extract of P. urinaria and Ellagic Acid were used to evaluate the anti-angiogenic effect in chorioallantoic membrane (CAM) in chicken embryo and human(More)
BACKGROUND This study was designed to obtain the chemical fingerprint and to investigate the effect of Phyllanthus urinaria on telomerase activity and apoptotic pathways in the human nasopharyngeal carcinoma cell line (NPC-BM1). MATERIALS AND METHODS The polyphenol compounds in P. urinaria were investigated by HPLC/MS. Cell viability with the treatment of(More)
BACKGROUND Ellagic acid (EA), a dietary polyphenolic compound, has been demonstrated to exert anti-angiogenic effect but the detailed mechanism is not yet fully understood. The aim of this study was to investigate whether the zinc chelating activity of EA contributed to its anti-angiogenic effect. METHODS AND PRINCIPAL FINDINGS The matrix(More)
