Project description:Curcumin, a yellow pigment extracted from the rhizome of the plant Curcuma longa (turmeric) has been widely used as a spice and herbal medicine in Asia. It has been suggested to have many biological activities such as anti-oxidative, anti-inflammatory, anti-cancer, chemopreventive, and anti-neurodegenerative properties. We evaluated the impact of curcumin on lifespan, fecundity, feeding rate, oxidative stress, locomotion and gene expression in two different wild type Drosophila melanogaster strains, Canton-S and Ives, under two different experimental conditions. We report that curcumin extended the lifespan of two different strains of Drosophila and was accompanied by protection against oxidative stress, improvement in locomotion and chemopreventive effects. Curcumin also modulated the expression of several aging related genes (genes with age-dependent changes in gene expression) such as mth, thor, InR, and JNK. In order to evaluate the impact of curcumin and aging on gene expression, we first determined which genes were affected by aging alone in Canton S flies. Age-related changes in gene expression were defined as changes in expression levels that occurred between 3 and 40 days of age (median lifespan). Among the 18,880 probe sets in the Affymetrix GeneChip® Drosophila Genome 2.0 Array, 1,383 genes (Data on file, 7.3%, P < 0.05) had statistically significant changes in expression levels during this time frame. We next determined the effect of curcumin on gene expression levels in young and aged Canton S flies. Gene expression were defined as changes in expression levels that occurred between 3 and 40 days of aged flies with or without curcumin-feeding.

Project description:Curcumin, derived from the rhizome of Curcuma longa is a natural anti-cancer agent and has been shown to inhibit proliferation and survival of tumor cells. Although the anti-cancer effects of curcumin are well established, detailed understanding of the signaling pathways altered by curcumin is still unclear. In this study, we carried out SILAC-based quantitative proteomic analysis of CAL 27 cell line, a HNSCC cell line to investigate tyrosine signaling in response to curcumin. Using high resolution Orbitrap Fusion™ Tribrid™ Fourier transform mass spectrometer, we identified 627 phosphotyrosine sites mapping to 357 proteins. We observed alterations in the level of phosphorylation of 307 sites corresponding to 204 proteins upon curcumin treatment.

Project description:Melanoma is the most aggressive form of skin cancer with estimated 48,000 deaths worldwide. The polyphenol curcumin derived from the plant Curcuma longa is well known for its anti-inflammatory and anti-cancerogenic properties. Accordingly, dietary intake of this compound may be suitable for melanoma prevention. However, how this compound affects basic cellular mechanisms in developing melanoma still remains elusive. Therefore, the aim of this study was to investigate for the first time the impact of oral curcumin administration on the miRNA signature of engrafting melanoma. For this purpose, the effects of a 4% curcumin diet on murine B78H1 melanoma were tested in a flank model. Curcumin diet or standard chow (control) was administered two weeks prior to tumor initiation until termination of the experiment. Highly significant chip-based miRNA array analysis was deployed to detect alterations in the miRNA signature of the tumors. Curcumin treatment significantly reduced the growth of the flank tumors. Furthermore the miRNA expression signature in tumors was substantially altered by curcumin intake with mmu-miR-205-5p over 100 times higher expressed when compared to controls. Putative targets of curcumin-induced up-regulated miRNAs were enriched in o-glycan biosynthesis, endoplasmatic reticulum protein processing and different cancer-related pathways. These findings demonstrate a profound alteration of the miRNA expression signature in engrafting curcumin-treated melanoma with mmu-miR-205-5p being up-regulated most significantly. Treatment of male C57BL/6 mice with induced flank tumors (injection of B78H1 cells) either with standard mouse chow (control n=6) or chow enriched with 4% of curcumin (treatment group n=7 )

Project description:<p><strong>BACKGROUND:</strong> Curcuma spp. (Zingiberaceae), are used as a spice and coloring agent. Their rhizomes and essential oils are known for medicinal properties, besides their use in the flavoring and cosmetic industry. Most of these biological activities were attributed to volatile and non-volatile secondary metabolites present in the rhizomes of Curcuma spp. The metabolite variations among the species and even cultivars need to be established for optimized use of Curcuma spp.</p><p><strong>OBJECTIVES:</strong> We compared the phytochemical profiles of rhizomes and their essential oils to establish the variability among seven cultivars: five of Curcuma longa L. (Alleppey Supreme, Duggirala Red, Prathibha, Salem, Suguna/PCT-13), and two of C. aromatica Salisb. (Kasturi Araku, Kasturi Avidi). The GC-MS and LC-MS-based analyses were employed to profile secondary metabolites of these selected cultivars.</p><p><strong>METHODS:</strong> Rhizomes of Curcuma spp. were subjected to hydro-distillation to collect essential oil and analyzed by GC-MS. The methanol extracts of fresh rhizomes were subjected to LC-MS analyses. The compounds were identified by using the relevant MS library databases as many compounds as possible.</p><p><strong>RESULTS:</strong> The essential oil content of the cultivars was in the range of 0.74% to 1.62%. Several compounds were detected from the essential oils and rhizome extracts by GC-MS and LC-MS, respectively. Of these, 28 compounds (13 from GCMS and 15 from LCMS) were common in all seven cultivars, e.g. α–thujene, and diarylheptanoids like curcumin. Further, a total of 39 new compounds were identified from C. longa L. and/or C. aromatica Salisb., most of them being cultivar-specific. Of these compounds, 35 were detected by GC-MS analyses of essential oils: phenol, 2-methoxy-3-(2-propenyl); santolina alcohol; to name a few. The other four compounds were detected by LC-MS of the methanolic extracts of the rhizomes, e.g., kaempferol 3,7-dimethyl ether and 5,7,8-trihydroxy-2′,5′-dimethoxy-3′,4′-methylene dioxyisoflavanone.</p><p><strong>CONCLUSIONS:</strong> We identified and recorded the variability in the metabolite profiles of essential oils and whole rhizome extracts from seven cultivars of Curcuma longa L. and C. aromatica Salisb. In. As many as 39 new metabolites were detected in these seven Indian cultivars of Curcuma spp. Many of these compounds have health benefits.</p>

Project description:Curcumin is an extract of the tumeric root that has been shown to have anti-tumor properties in laboratory studies. Curcumin, and its parent spice, turmeric (curcuma longa), are the 4th most commonly purchased dietary supplement in the U.S. Many cancer patients take curcumin during their treatment for cancer because of the purported health benefits.
This research study is designed to learn more about the safety, pharmacokinetics and effectiveness of irinotecan when given in combination with curcumin in patients with metastatic colorectal cancer. The study of how the body absorbs, processes and eliminates drugs is called pharmacokinetics (PK). One of the main purposes of this study is to better understand the interaction between curcumin and irinotecan by measuring levels of irinotecan in the blood (ie. measure irinotecan PK) when a patient also takes curcumin. Information collected from this study could result in improved dosing guidelines and lead to more effective treatment of your cancer with less toxicity.

Project description:Colorectal cancer is a major problem in the United States and other developed countries. A safe and effective chemopreventive agent could reduce the burden of colorectal neoplasia. Curcumin, is a product that is derived from Curcuma longa. It has been used for thousands of years as a traditional remedy. Curcumin blocks a number of targets involved in tumor initiation, promotion, and progression, and is considered a promising chemopreventive agent. The investigators propose to enroll 40 patients after screening colonoscopy who will have rectal biopsies at baseline and after 4 weeks of curcumin 4 grams per day. The investigators will use microarray analysis to identify genes that are modified by curcumin that could be used as biomarkers in future chemoprevention studies. The study will also evaluate tolerability and toxicity.

Project description:Curcumin is a polyphenolic compound extracted from the turmeric plant (Curcuma longa) and has been extensively studied for its anti-inflammatory and anti-proliferative properties. The safety and effectiveness of curcumin have been thoroughly proven. However, the mechanisms underlying the treatment of osteoarthritis remain unclear. This study aimed to reveal the potential mechanism of curcumin in the treatment of osteoarthritis through metabolomics and transcriptomics. First, we verified the effect of curcumin on inflammatory factors in human articular chondrocytes. Secondly, we used cellular metabolomics to explore the cellular metabolic mechanism of curcumin against osteoarthritis. Third, we evaluated differences in gene expression in human articular chondrocytes by transcriptomics. Finally, to evaluate essential targets and elucidate the underlying mechanisms of curcumin in the treatment of osteoarthritis, we performed a screen for proteins in pathways shared by metabolomics and transcriptomics. Our results showed that curcumin significantly reduced the levels of inflammatory markers, such as IL-β, IL-6, and TNF-α, in human articular chondrocytes. Cellular metabolomics identified 106 differential metabolites, including beta-aminopropionitrile, 3-amino-2-piperidone, pyrrole-2-carboxaldehyde, and various other components. Transcriptome analysis yielded 1050 differential mRNAs. Enrichment analysis showed that differential metabolites and mRNA were significantly enriched in 7 pathways including glycine, serine, and threonine metabolism; interconversion of pentose and glucuronic acid; glycerolipid metabolism; histidine metabolism; mucin type O-glycan biosynthesis; phosphoinositide metabolism; and cysteine and methionine metabolism. A total of 23 key targets were identified to be involved in these pathways. We speculate that curcumin may alleviate osteoarthritis by targeting key proteins involved in glycine, serine, and threonine metabolism, inhibiting pyruvate production, and regulating glycolysis.
