• Cancer Prevention Diet - Nutrition Science News, 8/99 - "Research suggests that curcumin, the bright yellow flavonoid present in turmeric (Curcuma longa) roots, selectively inhibits thromboxane production while sparing prostacyclin. Thromboxane is a potent inflammatory compound produced by the body in response to injury or irritation. It causes blood vessels to constrict and the blood to clot, while prostacyclin is an inflammatory mediator that can respond to tissue injury without leading to further inflammation. Inhibiting thromboxane prevents excessive inflammatory response and reduces damage to vascular endothelia. Curcumin has also been shown to inhibit tobacco smoke mutagenicity, suggesting it may help protect the vascular endothelia from damage caused by smoking"

Abstracts:

• Curcumin inhibits adipogenesis in 3T3-L1 adipocytes and angiogenesis and obesity in C57/BL mice - J Nutr. 2009 May;139(5):919-25 - "Supplementing the high-fat diet of mice with curcumin did not affect food intake but reduced body weight gain, adiposity, and microvessel density in adipose tissue, which coincided with reduced expression of vascular endothelial growth factor (VEGF) and its receptor VEGFR-2. Curcumin increased 5'AMP-activated protein kinase phosphorylation, reduced glycerol-3-phosphate acyl transferase-1, and increased carnitine palmitoyltransferase-1 expression, which led to increased oxidation and decreased fatty acid esterification ... Our findings suggest that dietary curcumin may have a potential benefit in preventing obesity"
• Curcumin and cancer: An "old-age" disease with an "age-old" solution - Cancer Lett. 2008 May 5 - "The activity of curcumin reported against leukemia and lymphoma, gastrointestinal cancers, genitourinary cancers, breast cancer, ovarian cancer, head and neck squamous cell carcinoma, lung cancer, melanoma, neurological cancers, and sarcoma reflects its ability to affect multiple targets. Thus an "old-age" disease such as cancer requires an "age-old" treatment"
• Curcumin induces cell-arrest and apoptosis in association with the inhibition of constitutively active NF-kappaB and STAT3 pathways in Hodgkin's lymphoma cells - Int J Cancer. 2008 Apr 3 - "Interestingly, curcumin caused cell cycle arrest in G2-M and a significant reduction (80-97%) in H-RS cell viability. Furthermore, curcumin triggered cell death by apoptosis, as evidenced by the activation of caspase-3 and caspase-9, changes in nuclear morphology and phosphatidylserine translocation. The above findings provide a mechanistic rationale for the potential use of curcumin as a therapeutic agent for patients with HL"
• Curcumin stimulates proliferation of embryonic neural progenitor cells and neurogenesis in the adult hippocampus - J Biol Chem. 2008 Mar 24 - "Administration of curcumin to adult mice resulted in a significant increase in the number of newly-generated cells in the dentate gyrus of hippocampus, indicating that curcumin enhances adult hippocampal neurogenesis"
• Effects of curcumin on bladder cancer cells and development of urothelial tumors in a rat bladder carcinogenesis model - Cancer Lett. 2008 Mar 12 - "Exposure of human bladder cancer cells to curcumin resulted in the induction of apoptotic cell death and caused cells to arrest in the G2/M phase. The anti-apoptotic Bcl-2 and Survivin protein was downregulated by the curcumin treatment together with enhancement of the Bax and p53 expression. The inhibitory activities of curcumin were stronger than those of cisplatin and could not be prevented by catalase pretreatment in T24 cells. Clonal assay indicated large-dose and short-term curcumin was lethal to bladder cancer cells. Moreover, the in vivo study revealed curcumin did induce apoptosis in situ, inhibit and slow the development of bladder cancer. These observations suggest that curcumin could prove an effective chemopreventive and chemotherapy agent for bladder cancer"
• The combination of epigallocatechin gallate and curcumin suppresses ERalpha-breast cancer cell growth in vitro and in vivo - Int J Cancer. 2007 Dec 20 - "Tumor volume in the EGCG + curcumin treated mice decreased 49% compared to vehicle control mice (p < 0.05), which correlated with a 78 +/- 6% decrease in levels of VEGFR-1 protein expression in the tumors. Curcumin treatment significantly decreased tumor protein levels of EGFR and Akt, however the expression of these proteins was not further decreased following combination treatment. Therefore, these results demonstrate that the combination of EGCG and curcumin is efficacious in both in vitro and in vivo models of ERalpha- breast cancer and that regulation of VEGFR-1 may play a key role in this effect"
• Effect of Curcumin on Inflammation and Oxidative Stress in Cisplatin-Induced Experimental Nephrotoxicity - J Agric Food Chem. 2007 Nov 15 - "curcumin has a protective effect on cisplatin-induced experimental nephrotoxicity, and this effect is attributed to its direct anti-inflammatory and strong antioxidant profile. Hence, curcumin has a strong potential to be used as a therapeutic adjuvant in cisplatin nephrotoxicity" - See Curcumin/turmeric products at iHerb.
• Curcumin for chemoprevention of colon cancer - Cancer Lett. 2007 Apr 18 - "Overwhelming in vitro evidence and completed clinical trials suggests that curcumin may prove to be useful for the chemoprevention of colon cancer in humans"
