News & Research:

  • Plant compounds give '1-2' punch to colon cancer - Science Daily, 7/22/16 - "The combination of two plant compounds that have medicinal properties -- curcumin and silymarin -- holds promise in treating colon cancer ... The combination of phytochemicals inhibited colon cancer cells from multiplying and spreading. In addition, when the colon cancer cells were pre-exposed to curcumin and then treated with silymarin, the cells underwent a high amount of cell death" - See curcumin products at Amazon.com and silymarin at Amazon.com.
  • Curcumin's ability to fight Alzheimer's studied - Science Daily, 1/12/15 - "Curcumin has demonstrated ability to enter the brain, bind and destroy the beta-amyloid plaques present in Alzheimer’s with reduced toxicity"
  • New research adds spice to curcumin's health-promoting benefits - Science Daily, 11/6/14 - "Curcumin powder was mixed with castor oil and polyethylene glycol in a process called nano-emulsion (think vinaigrette salad dressing), creating fluid teeming with microvesicles that contain curcumin. This process allows the compound to dissolve and be more easily absorbed by the gut to enter the bloodstream and tissues ... concentrations of the emulsified curcumin in blood were more than 10 times higher than of curcumin powder suspended in water"
  • Turmeric compound boosts regeneration of brain stem cells - Science Daily, 9/25/14 - "A bioactive compound found in turmeric promotes stem cell proliferation and differentiation in the brain ... The findings suggest aromatic turmerone could be a future drug candidate for treating neurological disorders, such as stroke and Alzheimer's disease"
  • Curcumin, special peptides boost cancer-blocking PIAS3 to neutralize cancer-activating STAT3 in mesothelioma - Science Daily, 9/18/14 - "common Asian spice and cancer-hampering molecules show promise in slowing the progression of mesothelioma, a cancer of the lung's lining often linked to asbestos ... application of curcumin, a derivative of the spice turmeric, and cancer-inhibiting peptides increase levels of a protein inhibitor known to combat the progression of this cancer ... asbestos does not always cause this particular cancer that kills 43,000 people worldwide each year. Many mesothelioma patients were never exposed to asbestos" - See curcumin products at Amazon.com.
  • Fresh faced: Looking younger for longer - Science Daily, 1/10/14 - "While UVB radiation easily causes sunburn, UVA radiation penetrates deeper, damaging our DNA by generating free radicals which degrades the collagen that gives skin its elastic quality ... the most potent anti-oxidants were those that targeted the batteries of the skin cells, known as the mitochondria. They compared these mitochondrial-targeted anti-oxidants to other non-specific antioxidants such as resveratrol, found in red wine, and curcumin found in curries, that target the entire cell. They found that the most potent mitochondrial targeted anti-oxidant was Tiron which provided 100%, protection of the skin cell against UVA sun damage and the release of damaging enzymes causing stress-induced damage ... Tiron is not a naturally occurring compound and has not yet been tested for toxicity in humans although there have been a few studies on rats ... Antioxidants in our diets from green tea, resveratrol which is found in red wine, turmeric which is used in curries and lycopene found in tomatoes, as well as some components in cosmetic creams, are known to neutralise this damage within the cells. They can slow down the damage and the rate of aging and potentially lower the rate of other sun-induced skin lesions ... Resveratrol, the antioxidant found in red wine, was found to protect against 22% of both the ultraviolet A radiation and stress-induced damage. NAC, a frequently used laboratory-based anti-oxidant, offered 20% protection against oxidative stress and 8% against UVA and curcumin offered 16% protection against oxidative stress and 8% against UVA" - See resveratrol products at Amazon.com, n-acetyl cysteine at Amazon.com and curcumin products at Amazon.com.
  • Curcumin may protect premature infants' lungs - Science Daily, 7/2/13 - "Premature infants often need the assistance of ventilators and forced oxygen therapy because they're frequently born with inadequate lung function. These therapies can cause the infants to suffer lasting lung damage and even death ... curcumin provided long-term protection against this damage ... curcumin provided protection against bronchopulmonary dysplasia (BDP), a condition characterized by scarring and inflammation, and against hyperoxia, in which too much oxygen enters the body through the lungs, for up to 21 days after birth. A previous LA BioMed study found curcumin provided protection for up to seven days after birth"
  • Food Supplement Linked to Lower PSA in Prostate Cancer - Medscape, 6/10/13 - "A commercially available food supplement that contains pomegranate, broccoli, green tea, and turmeric significantly lowers prostate-specific antigen (PSA) levels ... made headlines around the world and caused the polyphenol-rich supplement, known as Pomi-T (nature Medical Products), to sell out within hours ... to receive the supplement 3 times a day for 6 months or placebo ... At 6-month follow-up, the median increase in PSA was 63.8% lower in the supplement groups than in the placebo group (14.7% vs 78.5; P =.0008). In addition, PSA levels were stable or lower than baseline more often in the supplement group (46% vs 14%"
  • Prostate cancer: Curcumin curbs metastases, study shows - Science Daily, 10/12/12 - "The new study was designed to investigate the efficacy of curcumin in the prevention of prostate cancer metastases, and to determine the agent's mechanism of action ... curcumin may be useful in the prevention of breast and prostate cancers -- which are both linked to inflammation -- and in reducing their metastatic potential ... This does not mean that the compound should be seen as a replacement for conventional therapies. However, it could play a positive role in primary prevention -- before a full-blown tumor arises -- or help to avert formation of metastases. In this context the fact that the substance is well tolerated is very important, because one can safely recommend it to individuals who have an increased tumor risk"
  • Specific Plants Protect Against Specific, Not All, Cancers - Medscape, 8/29/12 - "Plants do not produce chemicals to help us fight cancer; essentially, plants produce an arsenal of toxic chemicals that kill yeast, bacteria, and insects. Out of this huge chemodiversity, research has shown that some of these chemicals have potent anticancer properties ... Probably the best example of a phytochemical that serves as an antiinflammatory is curcumin. "Turmeric is the most potent source of curcumin, and curcumin is the most potent antiinflammatory phytochemical we know,""
  • Curry Compound May Lower Diabetes Risk - WebMD, 7/31/12 - "All of the people in the study had been diagnosed with prediabetes. But according to the findings, none of the participants who took capsules of curcumin for nine months developed type 2 diabetes. By contrast, 16.4% of those who received a placebo did develop type 2 diabetes during the study period"
  • Curcumin Holds Promise as Treatment for Brain Tumors - Medscape, 3/29/12 - "Curcumin, a major component of the spice turmeric, has been shown to have chemopreventive and chemotherapeutic properties ... one of the interesting things about curcumin is that it can cross the blood-brain barrier ... Curcumin can induce apoptosis in a variety of tumor cells and has also prevented tumor initiation and growth in experimental models ... curcumin specifically binds to and crosslinks to a protein that is involved in cell-cycle regulation ... is the great thing about curcumin because if it only targets tumor cells, then it has very few — if any — side effects"
  • Curcumin and Piperine Prevent Remodeling of Aorta - Medscape, 12/26/11 - "N-nitro-L-arginine-methylester (L-NAME) is a nonspecific inhibitor of all three NO synthase (NOS) isoforms (neuronal - nNOS; inducible - iNOS; endothelial - eNOS) and causes an increase of blood pressure in a dose-dependent manner when administered to the experimental animals ... Administration of piperine or curcumin to animals with L-NAME-induced hypertension lead to a decrease of blood pressure, curcumin causing a more significant drop. Similar hypertension reducing effect of curcumin has been reported recently by Nakmreong et al.[34] Another study[25] registered a significant decrease of blood pressure after intravenous piperine administration. Piperine treatment was effective also in lowering blood pressure in rats with L-NAME-induced experimental hypertension described by Kumar et al.[36] The combination of curcumin and piperine in our experiment did not cause a statistically significant blood pressure decrease (with the exception of the third week) but it is apparent that it copies the course of the piperine graph curve. These differences in the results are probably related to different mechanisms of effect by the spices on blood pressure"
  • The Doctor's Remedy: Turmeric for Joint Pain - NYTimes.com, 10/19/11 - "Physician: Dr. Minerva Santos, director of integrative medicine at Northern Westchester Hospital in New York ... Recommended Remedy: Turmeric for joint pain ... What the Doctor Says: ... She recommends a dose of 1,000 milligrams a day. The benefit of buying it in a bottle, she said, is that it’s usually combined with a compound called piperine, which aids absorption"
  • Primary component in curry spice kicks off cancer-killing mechanisms in human saliva - Science Daily, 9/12/11 - "Curcumin, the main component in the spice turmeric used in curry, suppresses a cell signaling pathway that drives the growth of head and neck cancer ... The inhibition of the cell signaling pathway also correlated with reduced expression of a number of pro-inflammatory cytokines, or signaling molecules, in the saliva that promote cancer growth ... it not only affected the cancer by inhibiting a critical cell signaling pathway, it also affected the saliva itself by reducing pro-inflammatory cytokines within the saliva ... To be effective in fighting cancer, the curcumin must be used in supplement form. Although turmeric is used in cooking, the amount of curcumin needed to produce a clinical response is much larger. Expecting a positive effect through eating foods spiced with turmeric is not realistic"
  • Curry spice could offer treatment hope for tendinitis - Science Daily, 8/9/11 - "Tendons, the tough cords of fibrous connective tissue that join muscles to bones, are essential for movement because they transfer the force of muscle contraction to bones. However, they are prone to injury, particularly in athletes who may overstretch themselves and overuse their joints. Tendinitis (or tendonitis) is a form of tendon inflammation, which causes pain and tenderness near to joints and is particularly common in shoulders, elbows, knees, hips, heels or wrists. Other examples of common tendon disease include tennis and golfer's elbow and Achilles tendinitis ... introducing curcumin in the culture system inhibits NF-kB and prevents it from switching on and promoting further inflammation ... The results follow on from another study by the Nottingham-Munich collaboration, published in the Journal of Biological Chemistry earlier this year, demonstrating that a compound found in red wine could have therapeutic potential for osteoporosis related bone loss in elderly patients, post-menopausal women and patients with rheumatoid arthritis ... The research found that resveratrol, a naturally occurring phytoestrogen found in the skin of red grapes, vines and various other fruits and nuts, inhibits inflammation in bone cells. Its effects extended to inhibiting the formation of osteoclasts, giant congregations of blood-derived cells responsible for bone degeneration, especially in osteoporosis in later life. Resveratrol prevented NF-kB from switching on to trigger inflammation" - See resveratrol products at Amazon.com and curcumin products at Amazon.com.
  • Curcumin compound improves effectiveness of head and neck cancer treatment, study finds - Science Daily, 5/19/11 - "A primary reason that head and neck cancer treatments fail is the tumor cells become resistant to chemotherapy drugs. Now, researchers at the University of Michigan Comprehensive Cancer Center have found that a compound derived from the Indian spice curcumin can help cells overcome that resistance ... When researchers added a curcumin-based compound, called FLLL32, to head and neck cancer cell lines, they were able to cut the dose of the chemotherapy drug cisplatin by four while still killing tumor cells equally as well as the higher dose of cisplatin without FLLL32 ... Typically, when cells become resistant to cisplatin, we have to give increasingly higher doses. But this drug is so toxic that patients who survive treatment often experience long-term side effects from the treatment"

  • Spices may boost breast health: Study - Nutra USA, 12/9/09 - "curcumin, found in turmeric, and piperine, found in black peppers, decreased the number of stem cells while having no effect on normal differentiated cells ... If we can limit the number of stem cells, we can limit the number of cells with potential to form tumours ... normal, non-cancerous stem cells were unaffected by the compounds, which appeared to selectively target the cancer stem cells" - [Abstract]
  • Targeting breast stem cells with the cancer preventive compounds curcumin and piperine - Breast Cancer Res Treat. 2009 Nov 7 - "Both curcumin and piperine inhibited mammosphere formation, serial passaging, and percent of ALDH+ cells by 50% at 5 muM and completely at 10 muM concentration in normal and malignant breast cells. There was no effect on cellular differentiation. Wnt signaling was inhibited by both curcumin and piperine by 50% at 5 muM and completely at 10 muM. Curcumin and piperine separately, and in combination, inhibit breast stem cell self-renewal but do not cause toxicity to differentiated cells. These compounds could be potential cancer preventive agents. Mammosphere formation assays may be a quantifiable biomarker to assess cancer preventive agent efficacy and Wnt signaling assessment can be a mechanistic biomarker for use in human clinical trials"
  • Curry compound kills cancer cells, study shows - MSNBC, 10/28/09 - "Researchers at the Cork Cancer Research Center in Ireland treated esophageal cancer cells with curcumin — a chemical found in the spice turmeric, which gives curries a distinctive yellow color — and found it started to kill cancer cells within 24 hours ... But these cells showed no evidence of suicide, and the addition of a molecule that inhibits caspases and stops this "switch being flicked' made no difference to the number of cells that died, suggesting curcumin attacked the cancer cells using an alternative cell signaling system"
  • Curcumin May Inhibit Nicotine-induced Activation Of Head And Neck Cancers - Science Daily, 10/4/09 - "HNSCC cells were pre-treated with curcumin and then nicotine was introduced.

  • Therapeutic Potential of Turmeric in Alzheimer's Disease: Curcumin or Curcuminoids? - Phytother Res. 2013 Jul 19 - "Alzheimer's disease (AD) is the most common form of dementia. There is limited choice in modern therapeutics, and drugs available have limited success with multiple side effects in addition to high cost. Hence, newer and alternate treatment options are being explored for effective and safer therapeutic targets to address AD. Turmeric possesses multiple medicinal uses including treatment for AD. Curcuminoids, a mixture of curcumin, demethoxycurcumin, and bisdemethoxycurcumin, are vital constituents of turmeric. It is generally believed that curcumin is the most important constituent of the curcuminoid mixture that contributes to the pharmacological profile of parent curcuminoid mixture or turmeric. A careful literature study reveals that the other two constituents of the curcuminoid mixture also contribute significantly to the effectiveness of curcuminoids in AD. Therefore, it is emphasized in this review that each component of the curcuminoid mixture plays a distinct role in making curcuminoid mixture useful in AD, and hence, the curcuminoid mixture represents turmeric in its medicinal value better than curcumin alone"

  • Efficacy and Safety of Curcumin in Major Depressive Disorder: A Randomized Controlled Trial - Phytother Res. 2013 Jul 6 - "60 patients diagnosed with MDD were randomized in a 1:1:1 ratio for six weeks observer-masked treatment with fluoxetine (20 mg) and curcumin (1000 mg) individually or their combination ... curcumin was well tolerated by all the patients. The proportion of responders as measured by the HAM-D17 scale was higher in the combination group (77.8%) than in the fluoxetine (64.7%) and the curcumin (62.5%) groups; however, these data were not statistically significant (P = 0.58). Interestingly, the mean change in HAM-D17 score at the end of six weeks was comparable in all three groups (P = 0.77). This study provides first clinical evidence that curcumin may be used as an effective and safe modality for treatment in patients with MDD without concurrent suicidal ideation or other psychotic disorders"
  • Curcumin: An Orally Bioavailable Blocker of TNF and Other Pro-inflammatory Biomarkers - Br J Pharmacol. 2013 Feb 20 - "TNF blockers are now being used for the treatment of osteoarthritis, inflammatory bowel disease, psoriasis, and ankylosis at a total cumulative market value of more than $20 billion/year. Besides being expensive ($15,000-20,000/person/year), these drugs must be injected and have enough adverse effects to be given a black label warning by the FDA. In the current report, we describe an alternative, curcumin (diferuloylmethane), a component of turmeric (Curcuma longa) that is very inexpensive, orally bioavailable, and highly safe in humans, yet can block TNF-α action and production in in vitro models, in animal models, and in humans. In addition, we provide evidence for curcumin's activities against all of the diseases for which TNF blockers are being used. Mechanisms by which curcumin inhibits the production and the cell signaling pathways activated by this cytokine are also discussed. With health care costs and safety being major issues today, this golden spice may help provide the solution"

  • Curcumin attenuates lipopolysaccharide-induced renal inflammation - Biol Pharm Bull. 2011;34(2):226-32 - "Renal inflammation is the main pathological change in many acute and chronic kidney diseases. Curcumin, a yellow pigment present in the rhizome of turmeric (Curcuma longa L. Zingiberaceae), was found to be a potential anti-inflammatory agent ... The results demonstrated that curcumin could inhibit LPS-induced renal MCP-1 mRNA expression. Curcumin also significantly inhibited the expression of MCP-1 and IL-2 mRNA in HK-2 cells, and partially inhibited the secretion of MCP-1 and IL-8. Furthermore, curcumin was found to inhibit the DNA-binding activity of NF-κB. The present study demonstrated that curcumin has a protective effect on LPS-induced experimental renal inflammation, and this effect might be attributed to its inhibitory effects on MCP-1 mRNA expression and DNA-binding activity of NF-κB. Hence, curcumin might be potentially useful in some kidney diseases by preventing renal inflammation"

  • Curcumin promotes apoptosis in A549/DDP multidrug-resistant human lung adenocarcinoma cells through an miRNA signaling pathway - Biochem Biophys Res Commun. 2010 Jul 10 - "Curcumin extracted from the rhizomes of C. longa L has been shown to have inhibitory effects on cancers through its anti-proliferative and pro-apoptotic activities. Emerging evidence demonstrates that curcumin can overcome drug resistance to classical chemotherapies. Thus, the mechanisms underlying the antitumor activities of curcumin require further study. In our study, we first demonstrated that curcumin had anti-cancer effects on A549/DDP multidrug-resistant human lung adenocarcinoma cells. Further studies showed that curcumin altered miRNA expression; in particular, significantly downregulated the expression of miR-186 * in A549/DDP. In addition, transfection of cells with a miR-186 * inhibitor promoted A549/DDP apoptosis, and overexpression of miR-186 * significantly inhibited curcumin-induced apoptosis in A549/DDP cells. These observations suggest that miR-186 * may serve as a potential gene therapy target for refractory lung cancer that is sensitive to curcumin"

  • Curcumin synergizes with resveratrol to inhibit colon cancer - Nutr Cancer. 2009;61(4):544-53 - "the combination of curcumin and resveratrol was found to be more effective in inhibiting growth of p53-positive (wt) and p53-negative colon cancer HCT-116 cells in vitro and in vivo in SCID xenografts of colon cancer HCT-116 (wt) cells than either agent alone. Analysis by Calcusyn software showed synergism between curcumin and resveratrol. The inhibition of tumors in response to curcumin and/or resveratrol was associated with the reduction in proliferation and stimulation of apoptosis accompanied by attenuation of NF-kappaB activity. In vitro studies have further demonstrated that the combinatorial treatment caused a greater inhibition of constitutive activation of EGFR and its family members as well as IGF-1R. Our current data suggest that the combination of curcumin and resveratrol could be an effective preventive/therapeutic strategy for colon cancer"
  • 1α,25-dihydroxyvitamin D_{3} Interacts with Curcuminoids to Stimulate Amyloid-β Clearance by Macrophages of Alzheimer's Disease Patient - J Alzheimers Dis. 2009 May 11 - "1,25D3 strongly stimulated Abeta phagocytosis and clearance while protecting against apoptosis. Certain synthetic curcuminoids in combination with 1,25D3 had additive effects on phagocytosis in Type I but not Type II macrophages. In addition, we investigated the mechanisms of 1,25D3 and curcuminoids in macrophages. The 1,25D3 genomic antagonist analog MK inhibited 1,25D3 but not curcuminoid effects, suggesting that 1,25D3 acts through the genomic pathway. In silico, 1,25D3 showed preferential binding to the genomic pocket of the vitamin D receptor, whereas bisdemethoxycurcumin showed preference for the non-genomic pocket. 1,25D3 is a promising hormone for AD immunoprophylaxis because in Type I macrophages combined treatment with 1,25D3 and curcuminoids has additive effects, and in Type II macrophages 1,25D3 treatment is effective alone. Human macrophages are a new paradigm for testing immune therapies for AD" - See vitamin D at Amazon.comand curcumin products at Amazon.com.
  • Curcumin sensitizes human colorectal cancer to capecitabine by modulation of cyclin D1, COX-2, MMP-9, VEGF and CXCR4 expression in an orthotopic mouse model - Int J Cancer. 2009 May 26 - "Because of the poor prognosis and the development of resistance against chemotherapeutic drugs, the current treatment for advanced metastatic colorectal cancer (CRC) is ineffective. Whether curcumin (a component of turmeric) can potentiate the effect of capecitabine against growth and metastasis of CRC was investigated ... In nude mice, the combination of curcumin and capecitabine was found to be more effective than either agent alone in reducing tumor volume (p = 0.001 vs. control; p = 0.031 vs. capecitabine alone), Ki-67 proliferation index (p = 0.001 vs. control) and microvessel density marker CD31. The combination treatment was also highly effective in suppressing ascites and distant metastasis to the liver, intestines, lungs, rectum and spleen. This effect was accompanied by suppressed expression of activated NF-kappaB and NF-kappaB-regulated gene products (cyclin D1,c-myc, bcl-2, bcl-xL, cIAP-1, COX-2, ICAM-1, MMP-9, CXCR4 and VEGF). Overall, our results suggest that curcumin sensitizes CRC to the antitumor and antimetastatic effects of capecitabine by suppressing NF-kappaB cell signaling pathway"

  • 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"
