Genome-wide microarray analysis of normal human fibroblasts in response to kaemferol, daidzein, kaemferol/genistein, and daidzein/genistein

ABSTRACT: 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.

A comparative analysis of genistein and daidzein in affecting lipid metabolism in rat liver

Project description:Effects of soy isoflavones, genistein and daidzein, on the hepatic gene expression profile and indices for lipid metabolism were compared in rats. The GeneChip data was normalized and summarized by using SuperNORM data service (Skylight Biotech Inc.). Significance of expressional change among groups was tested by 2-way ANOVA on the normalized CEL data, which was deposited in a tab-separated ASCII text format. Principal components were identified on the summarized gene data. Three groups of rats were fed with an experimental diet containing 2 g/kg of either genistein or daidzein, or a control diet free of isoflavone for 14 days. The basal composition of the experimental diet was (in g/kg): casein, 200; palm oil, 100; corn starch, 150; cellulose, 20; mineral mixture (AIN-93G), 35; vitamin mixture (AIN-93), 10; L-cystine, 3.0; choline bitartrate, 2.0 and sucrose to 1 kg.

Genome-wide microarray analysis of normal human keratinocytes in response to genistein

Project description:Establishment of a transcriptomic profile of human cells treated with genistein with particular emphasis on the assessment of the role of this isoflavone in regulation of expression of psoriasis-related genes stands for the present study. The hypothesis tested was that genistein modulates activity of psoriasis-related genes, by reducing the expression efficiency of genes revealing enhanced activity in psoriatic cells, and by stimulating the expression efficiency of genes revealing decreased activity in psoriatic cells. Results provide important information concerning the extent of action of genistein at the molecular level in terms of modulation of gene expression by this substance.

Genistein treatment effects upin human prostate

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.
