A novel formulation of curcumin in combination with the phospholipids was developed to overcome the limitation of absorption and to investigate the protective effect of curcumin-phospholipid complex on carbon tetrachloride induced acute liver damage in rats. The antioxidant activity of curcumin-phospholipid complex (equivalent of curcumin 100 and 200 mg/kg body weight) and free curcumin (100 an...

BACKGROUND Curcumin has a variety of pharmacological effects. However, poor water solubility and low oral bioavailability limit its clinical utility. A delivery system for nanostructured lipid carriers has been reported to be a promising approach to enhancing the oral absorption of curcumin. The aim of the present study was to investigate the pharmacokinetics, tissue distribution, and relative ...

Curcumin, a constituent of the spice turmeric, has been shown to reduce the adenoma burden in rodent models of colorectal cancer accompanied by a reduction of levels of the oxidative DNA adduct 3-(2-deoxy-h-di-erythro-pentafuranosyl)-pyr[1,2-A]-purin-10(3H)one (M1G) and of expression of the enzyme cyclooxygenase-2 (COX-2). We tested the hypothesis that pharmacologically active levels of curcumi...

Curcumin, a constituent of the spice turmeric, has been shown to reduce the adenoma burden in rodent models of colorectal cancer accompanied by a reduction of levels of the oxidative DNA adduct 3-(2-deoxy-beta-di-erythro-pentafuranosyl)-pyr[1,2-alpha]-purin-10(3H)one (M(1)G) and of expression of the enzyme cyclooxygenase-2 (COX-2). We tested the hypothesis that pharmacologically active levels o...

Curcumin, a traditional medicine, exhibits anti-carcinogenic properties in various cell lines and animals. As a phenolic compound, curcumin is light-sensitive and photoactived curcumin exhibits a greater anticancer effect compared with curcumin alone. However, the mechanisms by which curcumin inhibits tumor cell growth in human nasopharyngeal carcinoma (NPC) cells following purple light (PL) ir...

CONTEXT Curcumin has a number of beneficial effects, such as functioning as a potent antioxidant,1 anti-inflammatory, 2 and anticancer agent. Because of its poor oral bioavailability, very high oral doses and repeated dosing have been used to obtain effective plasma levels, with mixed results. High doses of curcumin may cause gastric disturbance, often resulting in poor patient compliance. OB...

Medulloblastoma (MB) is the most common malignant brain tumor in children. Bcl-2 and MMP-9 promote the pathogenesis and progression of MB. The expression of both bcl-2 and MMP-9 is regulated by the transcription factor NF-kappaB. Curcumin, a natural food additive, has a potent anti-proliferative effect, presumably mediated through NF-kappaB suppression. The tumor-suppressing effects of curcumin...

Curcumin, which is extracted from the plant Curcuma longa, has been used in the therapeutic arsenal for clinical oncology. Curcumin has chemopreventive and antitumoral activities against some aggressive and recurrent cancers. The expressions and activities of various proteins, such as inflammatory cytokines and enzymes, transcription factors, and gene-products linked with cell survivals and pro...

Curcumin is a multifunctional and natural agent considered to be pharmacologically safe. However, its application in the food and medical industry is greatly limited by its poor water solubility, physicochemical instability and inadequate bioavailability. Nanoliposome encapsulation could significantly enhance the solubility and stability of curcumin. Curcumin nanoliposomes exhibited good physic...

AIM Curcumin has been demonstrated to have antitumor effects including radiosensitization by modulating many molecular targets including p53. Herein, we investigated the radiosensitizing effect of curcumin in p53 mutant Ewing's sarcoma (ES) cells. MATERIALS AND METHODS Cells exposed to radiation with or without curcumin were examined for transcriptional and translational levels of p53 downstr...
