Project description:Establishment of a transcriptomic profile of human cells treated with kaemferol, daidzein, kaemferol/genistein, or daidzein/genistein with particular emphasis on signature of genes coding for enzymes involved in glycosaminoglycan synthesis stands for the present study. The hypothesis tested was that kaemferol, daidzein, kaemferol/genistein, and daidzein/genistein influence expression of some genes, among which are those coding for enzymes required for the synthesis of different GAGs being pathologically accumulated in mucopolysaccharidoses. Results provide important information concerning the extent of action of kaemferol, daidzein, kaemferol/genistein, and daidzein/genistein at the molecular level in terms of modulation of gene expression.

Project description:Prior studies support the notion that the experimental chemopreventive agent, genistein, inhibits prostate cancer (PCa) cell movement in humans and that this in turn inhibits metastatic spread, thereby preventing PCa-specific death. As many effects have been ascribed to genistein, it has been considered a non-specific agent. However, its effects are concentration-dependent, and the vast majority of studies use concentrations greater than 3 logs above those associated with dietary consumption. Genistein is found in soy, and individuals consuming soy-based diets have blood concentrations of free genistein in the low nanomalar range. Using dosing guided by phase I pharmacokinetic studies in US men, prospective treatment of men on a phase II trial with genistein for one month prior to radical prostatectomy for localized PCa. Here we conducted an unbiased screening for effects of genistein in prostate as well as evaluate changes between normal and cancer cells.

Project description:Aging and age-related pathologies can be delayed by specifically targeting the senescence-associated secretory phenotype (SASP), a hallmark feature of senescent cells. Achieving the goal using natural or synthetic agents would have a tremendous impact on the quality of lifespan and burden of age-related chronic diseases. We report the potential of rutin, a bioactive phytochemical component derived from natural plants specifically ginkgo boliva, in targeting senescent cells via suppression of the SASP. This study demonstrates the efficacy of rutin as medicinal agent in controlling the influence of senescent human stromal cells and provides a strong rationale for its future use in aging intervention and geriatric medicine.

Project description:Damage of the intestinal epithelial barrier by xenobiotics or reactive oxygen species and a dysregulated immune response are both factors involved in the pathogenesis of inflammatory bowel diseases (IBD). Curcumin and rutin are polyphenolic compounds known to have anti-oxidant and anti-inflammatory activities, but their mechanism(s) of action are yet to be fully elucidated. Mdr1a-/- mice spontaneously develop intestinal inflammation, predominantly in the colon, with pathology similar to IBD, so this mouse model is relevant for studying diet-gene interactions and potential effects of foods on remission or development of IBD. This study tested whether the addition of curcumin or rutin to the diet would alleviate colonic inflammation in mdr1a-/- mice. Using whole-genome microarrays, the effect of dietary curcumin on gene expression in colon tissue was also investigated. Twelve mice were randomly assigned to each of three diets; control (AIN-76A), control + 0.2% curcumin or control + 0.1% rutin and monitored from the age of 7 to 24 weeks. Curcumin, but not rutin, significantly reduced histological signs of colonic inflammation in mdr1a-/- mice. Microarray and pathway analyses suggested that the effect of dietary curcumin on colon inflammation could be via an up-regulation of xenobiotic metabolism and a down-regulation of pro-inflammatory pathways probably mediated by PXR and PPARï¡ activation of RXR. These results reveal the potential of global gene expression and pathway analyses to study and better understand the effect of foods in colonic inflammation. Experiment Overall Design: Twelve mice were randomly assigned to each of three diets; control (AIN-76A), control + 0â¢2% curcumin or control + 0â¢1% rutin and monitored from the age of 7 to 24 weeks. As only curcumin significantly reduced colonic HIS, comparison of the gene expression levels in colon was carried out using total RNA from colon tissue of four mdr1a-/- mice from the control group (high HIS) and four mdr1a-/- mice from the curcumin group (low HIS). A reference design with eight arrays was used for this comparison, where each individual RNA sample was hybridized in the array with the reference RNA, totalizing 4 biological replicates per treatment.

Project description:Colorectal neoplasms are the third most common malignancies in the United States. Patients with metastatic (stage IV) colorectal cancer have a median life expectancy of 2 years. The response rates to chemotherapy range from 35-40%.
Epidemiologic evidence suggests that soy compounds may reduce the incidence of colorectal cancers. Laboratory analyses demonstrate that genistein, a soy-derived compound, may inhibit Wnt signaling, a pathway activated in majority of colorectal cancers. Laboratory observations also demonstrate that genistein may augment growth inhibition when combined with chemotherapeutic agents of 5-Fluorouracil and platinum compounds.
Based on pre-clinical data the investigators hypothesize that combining genistein with the standard of care chemotherapeutic regimens will reduce chemotherapy resistance and improve response rates in patients. The aim of the study is to add genistein to the regimens of FOLFOX or FOLFOX-Avastin in patients with newly diagnosed stage IV colon or rectal neoplasms.

Project description:Gene expression profiling to identify genes significantly modulated by low and high doses of genistein in LNCaP cells. Significant genes were identified using StepMiner analysis and significantly altered pathways with Ingenuity Pathways analysis. Genistein significantly altered expression of transcripts involved in cell growth, carcinogen defenses and steroid signaling pathways. The effects of genistein on these pathways were confirmed by directly assessing dose-related effects on LNCaP cell growth, NQO-1 enzymatic activity and PSA protein expression.

Project description:Epidemiological data indicate that consumption of soy-based food significantly reduces the cancer risk in human through interaction with estrogen receptors and the ‘phytoestrogen’ genistein present in the soy is responsible for this chemopreventive activity. The epigenome regulatory effect of genistein also reported but the key mechanism behind this effect remain elusive. In this current project, we reported the epigenome modulation effect of genistein using MDA-MB231 cells. Cells were treated with low-dose genistein for >1 month and the stable epigenetic alterations were analyzed by partial MNase digestion and TMT-based quantitative proteomics based chromatome mapping approach. We identified a total of 3177 chromatin-bound proteins with high confidence, including 882 proteins that displayed altered binding topology after cell conditioning with genistein. Prolonged phytochemical exposure permanently modified the binding topology of the key epigenetic regulators and preserved their binding topology in untreated progeny. Genistein induced altered epigenome modulation negatively regulates the expression of cell proliferation genes and suppress cell growth. In contrast, previously exposed cells displayed reduced expression of DNA repair genes and enhanced genotoxic stress upon genistein withdrawal.
