Peptides derived from dietary proteins, have been reported to display significant antioxidant activity, which may exert notably beneficial effects in promoting human health and in food processing. Recently, much research has focused on the generation, separation, purification and identification of novel peptides from various protein sources. Some(More)
OBJECTIVE To investigate the inhibitory effect of resveratrol on the metastasis-associated ability of human highly metastatic ovarian carcinoma HO-8910PM cells in vitro. METHODS MTf assay was used to examine the cytotoxicity of resveratrol in HO-8910PM cells; Transwell Chamber assay was performed to determine the effect on invasion and migratory capacity(More)
Mangiferin is a xanthone widely distributed in higher plants showing antioxidative, antiviral, anticancer, antidiabetic, immunomodulatory, hepatoprotective and analgesic effects. In the present study, an ultrasonic-assisted extraction method was developed for the effective extraction of mangiferin from mango leaves. Some parameters such as ethanol(More)
BACKGROUND Increasing evidence supports the anticancer effects of morin in vitro and in vivo. However, the role of morin-7-sulphate sodium (NaMoS), a water-soluble flavonoid derivative synthesized from morin remains unclear. The present study investigated the tumor suppression by NaMoS in mouse melanoma cells. MATERIALS AND METHODS We synthesized the(More)
Aloe-emodin (AE) has been demonstrated to have antitumor activity in several tumor cells. However, no information is available on the effect of AE on metastasis in human carcinoma cells. This study was designed to investigate the inhibitory effect of AE on the metastasis potential of HO-8910PM cell line in vitro, and the role of AE in focal adhesion kinase(More)
OBJECTIVE To investigate the effect of Aloe emodin (AE) on the invasive and metastatic abilities of human high metastatic breast cancer MDA-MB-231 cells. METHODS MTT assay was used to evaluate the viability of MDA-MB-231 cells after treated with AE for 6 h and 24 h. The adhesive potential of MDA-MB-231 cells to FN and LN was tested by cell-matrix adhesion(More)
OBJECTIVE To observe the effects of seven kinds of flavonoids on recombinant human phosphatase of regenerating liver-3 activity. METHODS The inhibitory effect of flavonoids was tested by DiFMUP assay. Calculation of IC50 values was performed according to the law of semi-effect-probit. RESULTS Myricetin and gossypin could significantly inhibit(More)
BACKGROUND & OBJECTIVE Cantharidin, a natural toxin, has specific antitumor actions. Many researches confirmed that nuclear factor-kappaB (NF-kappaB) closely relates with invasion and metastasis of tumor. This study was designed to investigate inhibitory effect of cantharidin on metastasis-related ability of human highly metastatic ovarian carcinoma cell(More)
RATIONALE AND OBJECTIVE This study aimed to investigate the clinical value of spectral computed tomography (CT) in the detection of cholesterol gallstones from surrounding bile. MATERIALS AND METHODS This study was approved by the institutional review board. The unenhanced spectral CT data of 24 patients who had surgically confirmed cholesterol gallstones(More)
