Regulation of Hepatic Detoxification Enzymes by Glucosinolate Breakdown Products in Cruciferous Vegetables
… two components. In addition to this, active glucosinolate breakdown products studied here also have anti-promotional effects through inhibition of AP-1 induced tumor promotion in vitro.

Microbial glucosinolate metabolism: Characterization of Enterococcus faecalis XL1 and functional analysis of a GH4 enzyme
Glucosinolates (GSLs), sulfur-containing plant metabolites abundant in cruciferous vegetables, are hydrolyzed to isothiocyanates (ITCs) – bioactive compounds with antimicrobial, anticancer, and anti-inflammatory properties. When plant myrosinases are inactivated by cooking, gut microbes become the …

Development of a Genetic Linkage Map of Broccoli and Identification of QTL Associated With Glucosinolate Variability
… with the variability of individual and/or total glucosinolate content at or above an LOD score of 3.0.

The Isolation and Evaluation of Biological Effects of the Glucosinolate Hydrolysis Product 1-Isothiocyanato-3-(methylsulfinyl)-Propane
… (IMSP) is a glucosinolate hydrolysis product formed from 3-methylsulfinylpropylglucosinolate when crucifers are eaten. The four most commonly consumed crucifers (cabbage, Brussels sprouts, cauliflower, and broccoli) have been shown to contain high …

Enhancing human health promoting activity through the regulation of the methyl jasmonate mediated glucosinolate biosynthesis in Brassica oleracea
… that contain various phytochemicals such as glucosinolates (GS) and flavonoids that have health-promoting bioactivity. Recent data suggest that methyl jasmonic acid (MeJA) can increase concentrations of GS and polyphenolics in Brassica plants. In Chapter 2 tissue/organ specific responses to …

The glucosinolate/myrosinase system: variation in glucosinolates, hydrolysis products, transcript abundance, and quinone reductase bioactivity in Brassica sp. crops
Glucosinolates, and more specifically their hydrolysis products, are secondary metabolites present in Brassica crops that are important for plant defense from insects and pathogens. In addition, these compounds have long been associated with anti-cancer activity in mammals through the induction of …

Genetic Constraints and the Evolution of Chemical Defenses in Multiple Tissues of Boechera stricta
… In my dissertation, I investigate how glucosinolates, biologically active secondary metabolites, evolve in multiple tissues of the crucifer Boechera stricta. I quantify variation in glucosinolate concentration and the relative ratio of each glucosinolate compound (hereafter called the …

Broccoli bioactives: impact on enzyme induction, estrogen metabolism and human cancer cell growth
… are traditionally attributed to high levels of glucosinolates and their bioactive breakdown products. A proposed mechanism of protection against estrogen-associated cancers by cruciferous vegetables is alteration of estrogen metabolism toward formation of less estrogenic metabolites. …

Digestive metabolism of glucosinolates: a novel approach using urinary markers for estimating the release of glucosinolate breakdown products in the gastro-intestinal tract of mammals.
Glucosinolates have been implicated as a mediator of the cancer-protective properties of cruciferous vegetables. Enzymatic hydrolysis of glucosinolates by plant or microbial myrosinase yields a range of metabolites including beneficial isothiocyanates. Little is known about the fate of …

Functional studies of lignin biosynthesis genes and putative flowering gene in Miscanthus x giganteus and studies on indolyl glucosinolate biosynthesis and translocation in Brassica oleracea
… studies on the accumulation and translocation of glucosinolates (GSs), bioactive secondary plant compounds, in broccoli plants. Changes in GS accumulation and gene expression levels in response to exogeneous methyl jasmonate (MeJA) treatment were analyzed in different tissue types at different …

Effectiveness of mustard short-cycle cover crops for management of Phytophthora capsici and Fusarium spp. in cucurbits
… not affected. In the greenhouse trial, thirteen glucosinolates were detected and quantified in both FBL and Tilney mustard cultivars. FBL roots had significantly lower total glucosinolate content (µmol/g) than FBL foliage. Conversely, Tilney roots had significantly higher glucosinolate content …

The Evolutionary Ecology of Arabidopsis Thaliana: Genotypic Diversity, Herbivory, and Elevated Carbon Dioxide
… responses of A. thaliana genotypes (i.e., glucosinolate contents and trichomes) to diamondback moth herbivory. Herbivory induced a significant 28% to 62% increase in glucosinolate concentrations, although only under elevated CO2. These inducible chemical responses were both …

The role of foliar glucosinolates in host plant resistance of oilseed rape and mustard to the Bertha armyworm and the diamondback moth
The relationships between host plant glucosinolates and feeding and growth of a polyphagous insect, the Bertha armyworm, Mamestra configurata Walker and field infestation levels of an oligophagous insect, the diamondback moth, Plutella xylostella L. were investigated. M. configurata reared on eight …

Post Harvest Treatment Effects on Crown-Cut Broccoli Shelf Life
… texture, ascorbic acid content, weight loss and glucosinolate retention in crown-cut heads of broccoli were studied. Oxygen and CO2 levels inside shrink wrap packages were also monitored. Shrink wrap packaging had a significant positive effect on hue angle (p<0.05). Packaging and post harvest …

Evaluation of the induction of rat hepatic and pancreatic glutathione S-transferases by treatment with the cruciferous nitrile, cyanohydroxybutene
… (CHB) is a nitrile derived from glucosinolates commonly found in cruciferous plants. Glucosinolate derivatives are believed to provide protection against carcinogens by inducing detoxifying including the glutathione S-transferase isoenzymes (GSTs). The GSTs catalyze the …

Enrichment of tomatoes and broccoli with specific bioactives for the reduction of prostate carcinogenesis
… sprouts, or broccoli enriched with indole glucosinolates or selenium for 7 days. All broccoli diets increased activity of colon quinone reductase (NQO1). Indole glucosinolate-enriched broccoli and selenium-enriched broccoli increased hepatic NQO1 and cytochrome P450 1A activity (P < 0.05). …

Dietary energy utilization in swine
… factor present in camelina cake (i.e., glucosinolate) did not affect the energy value of diet and additivity of dietary energy. However, dietary net energy value was affected by age of weaned pigs and increased with increasing age of pigs.
