BACKGROUND Curcumin has shown to affect sperm motility and function in vitro and fertility in vivo. The molecular mechanism(s) by which curcumin affects sperm motility has not been delineated. Since modulation of intracellular pH (pHi) and plasma membrane polarization is involved in sperm motility, the present study was conducted to investigate the effect of curcumin on these sperm (human and m...

Curcumin has been documented to exert anticancer effects by interacting with altered proliferative and apoptotic pathways in cancer models. In this study, we evaluated the potential of curcumin to reverse promoter methylation of the p15 gene in Raji cells and its ability to induce apoptosis and genomic instability. Anti-neoplastic action of curcumin showed an augmentation in reactive oxygen spe...

BACKGROUND Curcumin is a promising candidate for a natural medicinal agent to treat chronic inflammatory diseases. Although CD4(+) T cells have been implicated in the pathogenesis of chronic inflammation, whether curcumin directly regulates CD4(+) T cells has not been definitively established. Here, we showed curcumin-mediated regulation of CD2/CD3/CD28-initiated CD4(+) T cell activation in vit...

BACKGROUND Curcumin, the principal curcuminoid of the popular Indian spice turmeric, has a wide spectrum of pharmaceutical properties such as antitumor, antioxidant, antiamyloid, and anti-inflammatory activity. However, poor aqueous solubility and low bioavailability of curcumin is a major challenge in its development as a useful drug. To enhance the aqueous solubility and bioavailability of cu...

OBJECTIVE To determine if curcumin has an antiproliferative effect on leiomyoma cells via apoptosis induction and whether curcumin impacts extracellular matrix (ECM) production by assessing the fibronectin expression in leiomyoma cells treated with curcumin. DESIGN Tissue culture study of immortalized human leiomyoma and patient-matched myometrial cells treated with curcumin. SETTING Univer...

Propionibacterium acnes acts a critical role in the development of inflammatory acne when it overgrows in pilosebaceous units. The spread of multiple drug resistance bacteria indicates a growing need for new antimicrobial agents. The objective of this study is to develop lipid vehicles to deliver curcumin and inhibit P. acnes in the skin. The inhibitory activities of the curcumin containing veh...

It is a well known fact curcumin; a coloring principle in turmeric has emerged as the most exploited phyto-constituents for its wide spectrum of biological activities. Mostly, it is available in the market as a mixture of three different constituents, commonly known as curcuminoids. These curcuminoids constitute majorly 75% curcumin (curcumin I), followed by 20% desmethoxycurcumin (curcumin II)...

Curcumin (diferulolylmethane), an active ingredient derived from the rhizome of the plant Curcuma longa, has anticancer activity in vitro and in vivo. Although curcumin possesses chemopreventive properties against several types of cancer, the molecular mechanisms by which it inhibits cell growth and induces apoptosis are not clearly understood. Our data revealed that curcumin inhibited growth a...

introduction: retinoic acid (ra), one of the syntetic vitamin a derivatives which has been frequently used as a drug to treat face acne, is known to have specific side effects on the testis, liver, and spleen, it is also known as an oxidative agent in high doses. therefore, we have tried to find a compound which would decrease its side effects. curcumin which is found in the rhizome of turmeric...

SCOPE Curcumin, a component of the spice turmeric, was tested for its potential hormetic anti-aging effects as an inducer of mild stress. METHODS AND RESULTS Early passage young human skin fibroblasts treated with low doses of curcumin (below 20 μM) showed a time- and concentration-dependent induction of heme oxygenase-1 (HO-1), followed by compensatory increase in glutathione-S-transferase a...
