Curcumin (diferuloylmethane) is a polyphenol derived from the plant Curcuma longa, commonly called turmeric. Extensive research over the last 50 years has indicated this polyphenol can both prevent and treat cancer. The anticancer potential of curcumin stems from its ability to suppress proliferation of a wide variety of tumor cells, down-regulate transcription factors NF- κB, AP-1 and Egr-1; down-regulate the expression of COX2, LOX, NOS, MMP-9, uPA, TNF, chemokines, cell surface adhesion molecules and cyclin D1; down-regulate growth factor receptors (such as EGFR and HER2); and inhibit the activity of c-Jun N-terminal kinase, protein tyrosine kinases and protein serine/threonine kinases. In several systems, curcumin has been described as a potent antioxidant and anti-inflammatory agent. Evidence has also been presented to suggest that curcumin can suppress tumor initiation, promotion and metastasis. Pharmacologically, curcumin has been found to be safe. Human clinical trials indicated no dose-limiting toxicity when administered at doses up to 10 g/day. All of these studies suggest that curcumin has enormous potential in the prevention and therapy of cancer. The current review describes in detail the data supporting these studies. Curcumin, derived from turmeric (vernacular name: Haldi), is a rhizome of the plant Curcuma longa. The medicinal use of this plant has been documented in Ayurveda (the Indianread more

Photophysics, photochemistry and photobiology of curcumin : Studies from organic solutions, bio-mimetics and living cells
TL;DR: The intracellular curcumin showed more fluorescence in tumor cells than in normal cells and fluorescence spectroscopy could be used to monitor its preferential localization in the membrane of tumor cells and the possibility of developingCurcumin, as a bimolecular sensitive fluorescent probe is discussed.

β-Cyclodextrin-curcumin self-assembly enhances curcumin delivery in prostate cancer cells
TL;DR: Cell proliferation and clonogenic assays demonstrated that beta-cyclodextrin-curcumin self-assembly enhanced curcumin delivery and improved its therapeutic efficacy in prostate cancer cells compared to freeCurcumin.

Pharmacokinetics and pharmacodynamics of curcumin
TL;DR: Curcumin's ability to alter gene transcription and induce apoptosis in preclinical models advocates its potential utility in cancer chemoprevention and chemotherapy.

Function and activation of NF-kappa B in the immune system.
TL;DR: The inhibition of NF-kappa B activation by antioxidants and specific protease inhibitors may provide a pharmacological basis for interfering with these acute processes in suppressing toxic/septic shock, graft-vs-host reactions, acute inflammatory reactions, severe phase response, and radiation damage.

TL;DR: Interestingly, the growth-promoting activity of c-Jun is mediated by repression of tumour suppressors, as well as upregulation of positive cell cycle regulators, whereas JunB has the converse effect.

TL;DR: A model has been proposed for the cytokine‐induced E‐selectin enhancer that is similar to the stereospecific complex proposed forThe inter‐ feron‐β gene promoter, in which multiple DNA bending proteins facilitate the assembly of higher order complexes of transcriptional activators that interact as a unit with the basal transcriptional machinery.
