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

Studies on the interaction of diacetylcurcumin with calf thymus-DNA
TL;DR: The interaction of diacetylcurcumin (DAC) with calf thymus-DNA (ct-DNA) has been investigated by spectroscopic and viscometric techniques and DAC was found to be a minor groove binder with a preference for the A-T region compared to the G-C region.

Regulation of PD-L1 Expression by NF-κB in Cancer.
Fabrizio Antonangeli,Ambra Natalini,Marina Chiara Garassino,Antonio Sica,Angela Santoni,Francesca Di Rosa +5 more
TL;DR: How NF-κB, a master transcription factor of inflammation and immunity, is emerging as a key positive regulator of PD-L1 expression in cancer is discussed, suggesting that PD- L1 is part of the tissue remodeling program in tumors.

Bioaccessibility and antioxidant activity of curcumin after encapsulated by nano and Pickering emulsion based on chitosan-tripolyphosphate nanoparticles
TL;DR: The findings showed that after subjecting to simulated GIT model, all the emulsion systems experienced a progressive increase in mean particle size, due to droplet flocculation and coalescence after digestion, which confirmed the protective effect of the emulsions systems on the antioxidant activity of curcumin.

Immunomodulatory effects of curcumin treatment on murine schistosomiasis mansoni.
TL;DR: Curcumin treatment modulates cellular and humoral immune responses of infected mice and lead to a significant reduction of parasite burden and liver pathology in acute murine schistosomiasis mansoni.

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.

AP-1 as a regulator of cell life and death

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: It is demonstrated that curcumin is not toxic to humans up to 8,000 mg/day when taken by mouth for 3 months and a biologic effect ofCurcumin in the chemoprevention of cancer is suggested.

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.
