Abstract
SCOPE Epidemiological evidence associates the consumption of cruciferous vegetables with reduced risk of several cancers, including renal cell carcinoma. Erucin can be generated by in vivo reduction of sulforaphane or by enzymatic hydrolysis of glucoerucin. Contrarily to sulforaphane, only limited studies have addressed the anticancer properties of erucin. This study aims at evaluating the impact of erucin on renal cell biology. METHODS AND RESULTS The effects of erucin were assessed in 786-O and Vero-E6 cells, representative of human renal cancer and non- cancer kidney cells, respectively. Erucin induced a concentration-dependent decrease in cell viability and cell cycle arrest at G2/Mitosis. In Vero-E6 cells erucin modestly reduced intracellular reactive oxygen species levels while in 786-O no effects were detected. After erucin treatment, both cell lines revealed altered morphology, with a concentration-dependent change from an elongated shape towards a smaller round conformation. Moreover, erucin affected cell adhesion and strongly altered the tubulin network structure and specifically microtubule polymerization. These results are in line with the observed decrease in collective and single cell migration and G2/Mitosis arrest. CONCLUSIONS Overall, erucin may have a beneficial impact in reducing the motility of renal cancer cells. Our results contribute to explore possible dietary approaches for secondary/tertiary renal cancer chemoprevention.

Cucurbitacin-B Exerts Anticancer Effects through Instigation of Apoptosis and Cell Cycle Arrest within Human Prostate Cancer PC3 Cells via Downregulating JAK/STAT Signaling Cascade. Pharmaceuticals (Basel) 2022; 15:ph15101229. [PMID: 36297341 PMCID: PMC9609558 DOI: 10.3390/ph15101229] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2022] [Revised: 09/30/2022] [Accepted: 09/30/2022] [Indexed: 11/30/2022] Open
Abstract
Cucurbitacin-B (Cur-B) is an analogue triterpenoid belonging to the Cucurbitaceae family. Previous reports have explicitly outlined various biological activities of Cucurbitaceae family members, including the anticancer activity of Cur-B. In the present study, we tried to elucidate the anticancer efficacy of Cur-B against prostate cancer PC3 cells. PC3 cells were exposed to purified Cur-B at 5, 10, 15, 20 and 25 µM for 24. Cur-B exposure reduced cell viability of PC3 cells at 5 µM (p < 0.05), with further reduction with increased Cur-B concentration (15 µM, p < 0.01 and 25 µM, p < 0.001). Cur-B also succeeded in instigating nuclear fragmentation and condensation, followed by activation of caspase-8, -9 and -3 proportionally with increasing concentrations of Cur-B. Treatment with Cur-B also instigated ROS-mediated oxidative stress both qualitatively and quantitatively at 5 µM, p < 0.05; 15 µM, p < 0.01 and 25 µM, p < 0.001. Increased ROS after Cur-B treatment also led to dissipation of mitochondrial membrane potential, thereby resulting in considerable apoptosis (p < 0.001), which, again, was proportionally dependent on Cur-B concentration. Cur-B exposure to PC3 cells was concomitantly followed by reduced cyclin D1, cyclin-dependent kinase 4 (CDK4) expression and augmented mRNA expression of CDK inhibitor p21Cip1. Intriguingly, Cur-B exposure also led to considerable downregulation of the JAK/STAT signaling cascade, which may be the reason behind Cur-B-mediated apoptosis and cell cycle arrest within PC3 cells. Therefore, these observations explicitly establish that Cur-B could serve in the prevention of prostate cancer.

Multi-Functional Development and Utilization of Rapeseed: Comprehensive Analysis of the Nutritional Value of Rapeseed Sprouts. Foods 2022; 11:foods11060778. [PMID: 35327200 PMCID: PMC8953081 DOI: 10.3390/foods11060778] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2022] [Revised: 03/03/2022] [Accepted: 03/04/2022] [Indexed: 02/04/2023] Open
Abstract
Rapeseed is the third largest oil crop in the world and the largest oil crop in China. The multi-functional development and utilization of rapeseed is an effective measure for the high-quality development of rapeseed industry in China. In this study, several basic nutrients of eight rapeseed sprouts and five bean sprouts (3–5 varieties each) were determined, including sugar, crude protein, crude fiber, vitamin E, minerals, fatty acids, amino acids, and glucosinolates. Data analysis revealed that compared with bean sprouts, rapeseed sprouts were nutritionally balanced and were richer in active nutrients such as glucose, magnesium, selenium, vitamin E, and glucosinolate. Moreover, rapeseed sprouts exhibited reasonable amino acid composition and abundant unsaturated fatty acids (accounting for 90.32% of the total fatty acids). All these results indicated the potential of rapeseed sprout as a functional vegetable. Subsequently, three dominant nutrients including vitamin E, glucosinolate, and selenium were investigated in seeds and sprouts of 44 B. napus L. varieties. The results showed that germination raised the ratio of α-tocopherol/γ-tocopherol from 0.53 in seeds to 9.65 in sprouts, greatly increasing the content of α-tocopherol with the strongest antioxidant activity among the eight isomers of vitamin E. Furthermore, germination promoted the conversion and accumulation of glucosinolate components, especially, glucoraphanin with strong anti-cancer activity with its proportion increased from 1.06% in seeds to 1.62% in sprouts. In addition, the contents of selenium, vitamin E, and glucosinolate in rapeseed sprouts were highly correlated with those in seeds. Furthermore, these three dominant nutrients varied greatly within B. napus varieties, indicating the great potential of rapeseed sprouts to be further bio-enhanced. Our findings provide reference for the multi-purpose development and utilization of rapeseed, lay a theoretical foundation for the development of rapeseed sprout into a functional vegetable, and provide a novel breeding direction.

Calabrese EJ, Kozumbo WJ. The phytoprotective agent sulforaphane prevents inflammatory degenerative diseases and age-related pathologies via Nrf2-mediated hormesis. Pharmacol Res 2020; 163:105283. [PMID: 33160067 DOI: 10.1016/j.phrs.2020.105283] [Citation(s) in RCA: 23] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/30/2020] [Revised: 10/23/2020] [Accepted: 10/23/2020] [Indexed: 12/17/2022]
Abstract
In numerous experimental models, sulforaphane (SFN) is shown herein to induce hormetic dose responses that are not only common but display endpoints of biomedical and clinical relevance. These hormetic responses are mediated via the activation of nuclear factor erythroid- derived 2 (Nrf2) antioxidant response elements (AREs) and, as such, are characteristically biphasic, well integrated, concentration/dose dependent, and specific with regard to the targeted cell type and the temporal profile of response. In experimental disease models, the SFN-induced hormetic activation of Nrf2 was shown to effectively reduce the occurrence and severity of a wide range of human-related pathologies, including Parkinson's disease, Alzheimer's disease, stroke, age-related ocular damage, chemically induced brain damage, and renal nephropathy, amongst others, while also enhancing stem cell proliferation. Although SFN was broadly chemoprotective within an hormetic dose-response context, it also enhanced cell proliferation/cell viability at low concentrations in multiple tumor cell lines. Although the implications of the findings in tumor cells are largely uncertain at this time and warrant further consideration, the potential utility of SFN in cancer treatment has not been precluded. This assessment of SFN complements recent reports of similar hormesis-based chemoprotections by other widely used dietary supplements, such as curcumin, ginkgo biloba, ginseng, green tea, and resveratrol. Interestingly, the mechanistic profile of SFN is similar to that of numerous other hormetic agents, indicating that activation of the Nrf2/ARE pathway is probably a central, integrative, and underlying mechanism of hormesis itself. The Nrf2/ARE pathway provides an explanation for how large numbers of agents that both display hormetic dose responses and activate Nrf2 can function to limit age-related damage, the progression of numerous disease processes, and chemical- and radiation- induced toxicities. These findings extend the generality of the hormetic dose response to include SFN and many other chemical activators of Nrf2 that are cited in the biomedical literature and therefore have potentially important public health and clinical implications.

Abstract
6-(methylsulfinyl) hexyl isothiocyanate (6-MITC), is the main bioactive compound present in Wasabia japonica rhizome. Several scientific studies have shown that 6-MITC possesses interesting antimicrobial, anti-inflammatory, antiplatelet and antioxidant properties which therefore suggested us it could have an interesting chemopreventive potential. In a recent publication, we demonstrated, in two different leukemia cell lines, its ability to modulate several mechanisms supporting its antitumor activity. For this reason, we thought useful to continue the research, by investigating the potential antimutagenic activity of 6-MITC and thus better define its profile as a possible chemopreventive agent. 6-MITC antimutagenic effect against two known mutagenic agents: the clastogen Mitomycin C (MMC) and the aneuplodogen Vinblastine (VINB), was analyzed, in terms of micronuclei frequency decrease, after short- and long- time treatment on TK6 human cells, using a new automated protocol of the “In Vitro Mammalian Cell Micronucleous Test” by flow cytometry. The results showed a different behavior of the isothiocyante. In particular, 6-MITC was unable to counteract the MMC genotoxicity, but when it was associated with VINB a statistically significant decrease in the micronuclei frequency was registered. Overall, the results obtained suggest a potential antimutagenic activity of 6-MITC, in particular against the aneuploidogen agents. This ability, to inhibit or counteract the mutations at the cellular level has a great therapeutic value and it represents a mechanism through a chemopreventive agent can express its activity.

Abstract
Introduction: Preclinical studies suggest that brassica vegetable diets decrease cancer risk, but epidemiological studies show varied effects, resulting in uncertainty about any health impact of brassicas. Factors controlling absorption of glucosinolate metabolites may relate to inconsistent results. We reported previously that subjects with BMI > 26 kg/m2 (HiBMI), given cooked broccoli plus raw daikon radish (as a source of plant myrosinase) daily for 17 days, had lower glucosinolate metabolite absorption than subjects given a single broccoli meal. This difference was not seen in subjects with BMI < 26 kg/m2 (LoBMI). Our objective in this current study was to determine whether a similar response occurred when cooked broccoli was consumed without a source of plant myrosinase. Methods: In a randomized crossover study (n = 18), subjects consumed no broccoli for 16 days or the same diet with 200 g of cooked broccoli daily for 15 days and 100 g of broccoli on day 16. On day 17, all subjects consumed 200 g of cooked broccoli. Plasma and urine were collected for 24 h and analyzed for glucosinolate metabolites by LC-MS. Results: There was no effect of diet alone or interaction of diet with BMI. However, absorption doubled in HiBMI subjects (AUC 219%, plasma mass of metabolites 202% compared to values for LoBMI subjects) and time to peak plasma metabolite values and 24-h urinary metabolites also increased, to 127 and 177% of LoBMI values, respectively. Conclusion: BMI impacts absorption and metabolism of glucosinolates from cooked broccoli, and this association must be further elucidated for more efficacious dietary recommendations. Clinical Trial Registration: This trial was registered at clinicaltrials.gov (NCT03013465).

Abstract
The consumption of cruciferous vegetables rich in isothiocyanates has long been associated with a reduced risk of various types of cancer. 4-(methylthio)butyl isothiocyanate also called erucin is an isothiocyanate present in appreciable quantity in the seeds of Eruca sativa Mill. plant. Although the literature has revealed its protective effects via inducing phase II enzymes and inhibiting carcinogen activating phase I enzymes, recent studies also suggest that, it inhibits the proliferation of cancer cells by altering the telomerase activity, dynamics of microtubules, expression of histone deacetylases, and other molecular pathways. With this in mind, the emphasis has been made to review the molecular targets involved in cancer prevention by 4-(methylthio)butyl isothiocyanate.

Abstract
Moringa oleifera is a worldwide cultivated edible and medicinal plant. Its seeds are rich in oil, proteins, and glucosinolates. A practical method was developed to simultaneously extract and separate the three groups of substances from M. oleifera seeds. Smashed seed material was loaded into columns with petroleum ether: ethanol 8:2 (PE-ethanol) and eluted sequentially with 4.8-fold PE-ethanol to extract oil, and 10.8-fold water to extract proteins and glucosinolates. More than 95% of oil, proteins, and glucosinolates were extracted. The extracts were separated automatically into ether (oil) phase and ethanol aqueous phase. The latter was further separated into proteins and glucosinolates by 70% ethanol precipitation. The main glucosinolate was identified by LC-MS as GLC (4-α-rhamnopyranosyloxy-benzyl glucosinolate). After purification, 22.3 g refined oil, 33.0 g proteins, and 5.5 g purified GLC from 100 g M. oleifera seeds were obtained. This study provides a simple and high-efficient method to utilize M. oleifera seeds.

Abstract
OBJECTIVES The study investigates measurable effects of cabbage leaf wraps on post-traumatic knee injury exudate absorption in men. DESIGN Case-control experiment on the same group of patients (before and after treatment). SETTINGS/LOCATION One academic center and two hospitals. SUBJECTS The study was carried out on a group of patients with different degrees of injury severity in the acute stage of the knee injury who were divided into three groups based on the width of suprapatellar recess gap (3-5 mm in group 1, 6-10 mm in group 2, and 11 mm or more in group 3) as assessed by ultrasonography. INTERVENTIONS Each group of patients was divided into two subgroups, one of which comprised patients whose knees were treated with wraps containing cabbage leaves with ice (cases) and the others comprised patients treated with wraps without cabbage leaves, with cooling dressing only (controls). RESULTS Significant progression in knee fluid uptake was observed in the acute stage of the knee injuries treated with cabbage wraps compared with control groups (p < 0.05). It was shown that the time, type of wraps, and a degree of severity of post-traumatic exudative knee inflammation affect the process of knee recovery (Friedman test for repeated measures p < 0.05). The most significant results were observed within first 24 h after the injury. Further decrease in the width of the recess gap after 5 days was observed. CONCLUSIONS Application of cabbage wraps with ice to the knee in men may promote a reduction of swelling (by accelerating absorption of knee exudates) if applied during the acute stage of the knee injury.

Abstract
Brassicaceae plants are renowned for their taste, aroma and trigeminal characteristics; predominantly bitter taste, sulfurous aroma, and pungency. Compounds responsible for these sensations include the glucosinolates (GSLs) and their hydrolysis products, particularly isothiocyanates (ITCs), but also sulfur-containing volatile compounds. This article reviews the relative importance of taste and flavor perceptions resulting from such compounds; collating evidence from papers where findings are based on sensory analytical correlations, and those that have extracted specific compounds prior to sensory evaluation. Where specific GSLs impart bitterness and many ITCs impart pungency, this is clearly not true for all GSLs and ITCs. Designing crop improvement strategies for sensory traits based on total GSL content would be flawed, as it does not consider the relative differences in sensory characteristics of different GSLs and ITCs, nor the contribution from other GSL hydrolysis products. In addition, some Brassicaceae plants are consumed raw, whilst others are cooked; this affects not only the hydrolysis of GSLs, but also the generation and release of sulfides. Therefore, in breeding new plant varieties, it is prudent to consider the individual GSLs, the typical cooking conditions the plant is subjected to, enzyme stability, and resultant composition of both GSL hydrolysis products (including ITCs) and sulfides.

Park YJ, Lee HM, Shin M, Arasu MV, Chung DY, Al-Dhabi NA, Kim SJ. Effect of different proportion of sulphur treatments on the contents of glucosinolate in kale ( Brassica oleracea var. acephala) commonly consumed in Republic of Korea. Saudi J Biol Sci 2017; 25:349-353. [PMID: 29472789 PMCID: PMC5815982 DOI: 10.1016/j.sjbs.2017.04.012] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2016] [Revised: 03/23/2017] [Accepted: 04/30/2017] [Indexed: 12/22/2022] Open
Abstract
Kale (Brassica oleracea L. Acephala Group) is the rich source of medicinal value sulphur compounds, glucosinolates (GLSs). The aim of this study was to investigate the effect of different proportion of sulphur (S) supplementation levels on the accumulation of GLSs in the leaves of the kale cultivar ('TBC'). High performance liquid chromatography (HPLC) separation method guided to identify and quantify six GSLs including three aliphatic (progoitrin, sinigrin and gluconapin) and three indolyl (glucobrassicin, 4-methoxyglucobrassicin and neoglucobrasscin) respectively. Analysis of these distinct levels of S supplementation revealed that the accumulation of individual and total GLSs was directly proportional to the S concentration. The maximum levels of total GLSs (26.8 µmol/g DW) and glucobrassicin (9.98 µmol/g DW) were found in lower and upper parts of the leaves supplemented with 1 mM and 2 mM S, respectively. Interestingly, aliphatic GSLs were noted predominant in all the parts (50.1, 59.3 and 56% of total GSLs). Among the aliphatic and indolyl GSLs, sinigrin and glucobrassicin account 35.3 and 30.88% of the total GSLs. From this study, it is concluded that supply of S enhance the GSLs accumulation in kale.

Activation of Sphingosine 1-Phosphate Receptor 1 Enhances Hippocampus Neurogenesis in a Rat Model of Traumatic Brain Injury: An Involvement of MEK/Erk Signaling Pathway. Neural Plast 2016; 2016:8072156.

Abstract
Among sphingosine 1-phosphate receptors (S1PRs) family, S1PR1 has been shown to be the most highly expressed subtype in neural stem cells (NSCs) and plays a crucial role in the migratory property of NSCs. Recent studies suggested that S1PR1 was expressed abundantly in the hippocampus, a specific neurogenic region in rodent brain for endogenous neurogenesis throughout life. However, the potential association between S1PR1 and neurogenesis in hippocampus following traumatic brain injury (TBI) remains unknown. In this study, the changes of hippocampal S1PR1 expression after TBI and their effects on neurogenesis and neurocognitive function were investigated, focusing on particularly the extracellular signal-regulated kinase (Erk) signaling pathway which had been found to regulate multiple properties of NSCs. The results showed that a marked upregulation of S1PR1 occurred with a peak at 7 days after trauma, revealing an enhancement of proliferation and neuronal differentiation of NSCs in hippocampus due to S1PR1 activation. More importantly, it was suggested that mitogen-activated protein kinase-Erk kinase (MEK)/Erk cascade was required for S1PR1-meidated neurogenesis and neurocognitive recovery following TBI. This study lays a preliminary foundation for future research on promoting hippocampal neurogenesis and improving TBI outcome.

Abstract
The present study envisages the cytotoxic potential of 3-butenyl isothiocyanate isolated from Brassica juncea L. Czern var. Pusa Jaikisan against the human cancer cell lines viz. prostate, bone osteosarcoma, cervical, liver, neuroblastoma and breast cancer. As the compound was observed to be more effective against prostate cancer cell line, therefore, this cell line was further used to study the mechanism of cell death using neutral red assay, reactive oxygen species assay, mitochondrial membrane potential assay, microscopic and cell cycle analysis. The mechanistic analysis indicated that it induced the cell death of prostate cancer cells via apoptosis and hence made it an excellent choice as an effective anticancer compound.

Abstract
BACKGROUND Oxheart cabbage (Brassica oleracea var. capitata) is a member of the Brassica genus. Although some studies on the anticancer effects of extracts from oxheart cabbage have been reported, comprehensive information on the bioactive fractions and components from oxheart cabbage extracts is still lacking. The aim of this study was to isolate and identify the bioactive fractions and components from oxheart cabbage seeds using activity-guided isolation methods. RESULTS The cytotoxicity and apoptotic effects of fraction II, fraction III, iberverin, sulforaphane and iberin from oxheart cabbage seed extract were investigated. The results showed that all five components had inhibitory effects on the in vitro growth of A549 cells which were dose-dependent. These compounds also changed the morphology of A549 cells, and their inhibitory activity on A549 cells was as follows: sulforaphane > iberin > iberverin > fraction III > fraction II. The IC50 values were 3.53 ± 0.63, 4.93 ± 1.02, 7.07 ± 0.51, 15.56 ± 0.24 and 27.32 ± 0.63 µg mL(-1) respectively. Fraction II, fraction III, iberverin, sulforaphane and iberin induced cell apoptosis by increasing early apoptosis and late apoptosis/necrosis, and activation of caspase-3, -8 and -9. CONCLUSION These results indicated that the decrease in A549 cell viability by active compounds from oxheart cabbage seed extract was due to the induction of apoptosis. © 2015 Society of Chemical Industry.

A mode of action of glucosinolate-derived isothiocyanates: Detoxification depletes glutathione and cysteine levels with ramifications on protein metabolism in Spodoptera littoralis. INSECT BIOCHEMISTRY AND MOLECULAR BIOLOGY 2016; 71:37-48.

Abstract
Glucosinolates are activated plant defenses common in the order Brassicales that release isothiocyanates (ITCs) and other hydrolysis products upon tissue damage. The reactive ITCs are toxic to insects resulting in reduced growth, delayed development and occasionally mortality. Generalist lepidopteran larvae often detoxify ingested ITCs via conjugation to glutathione (GSH) and survive on low glucosinolate diets, but it is not known how this process influences other aspects of metabolism. We investigated the impact of the aliphatic 4-methylsulfinylbutyl-ITC (4msob-ITC, sulforaphane) on the metabolism of Spodoptera littoralis larvae, which suffer a significant growth decline on 4msob-ITC-containing diets while excreting ITC-glutathione conjugates and their derivatives in the frass. The most striking effects were a decrease of GSH in midgut tissue and hemolymph due to losses by conjugation to ITC during detoxification, and a decline of the GSH biosynthetic precursor cysteine. Protein content was likewise reduced by ITC treatment suggesting that protein is actively catabolized in an attempt to supply cysteine for GSH biosynthesis. The negative growth and protein effects were relieved by dietary supplementation with cystine. Other consequences of protein breakdown included deamination of amino acids with increased excretion of uric acid and elevated lipid content. Thus metabolic detoxification of ITCs provokes a cascade of negative effects on insects that result in reduced fitness.

Abstract
Hydrogen sulfide (H2S) was originally considered toxic at elevated levels; however just in the past decade H2S has been proposed to be an important gasotransmitter with various physiological and pathophysiological roles in the body. H2S can be generated endogenously from L-cysteine by multiple enzymes, including cystathionine gamma-lyase, cystathionine beta-synthase, and 3-mercaptopyruvate sulfurtransferase in combination with cysteine aminotransferase. Prostate cancer is a major health concern and no effective treatment for prostate cancers is available. H2S has been shown to inhibit cell survival of androgen-independent, androgen-dependent, and antiandrogen-resistant prostate cancer cells through different mechanisms. Various H2S-releasing compounds, including sulfide salts, diallyl disulfide, diallyl trisulfide, sulforaphane, and other polysulfides, also have been shown to inhibit prostate cancer growth and metastasis. The expression of H2S-producing enzyme was reduced in both human prostate cancer tissues and prostate cancer cells. Androgen receptor (AR) signaling is indispensable for the development of castration resistant prostate cancer, and H2S was shown to inhibit AR transactivation and contributes to antiandrogen-resistant status. In this review, we summarized the current knowledge of H2S signaling in prostate cancer and described the molecular alterations, which may bring this gasotransmitter into the clinic in the near future for developing novel pharmacological and therapeutic interventions for prostate cancer.

Abstract
Exposure to benzene promotes oxidative stress through the production of ROS, which can damage biological structures with the formation of new metabolites which can be used as markers of oxidant/antioxidant imbalance. This study aims to assess modifications in circulating levels of advanced oxidation protein products (AOPP), advanced glycation end-products (AGE) and serum reactive oxygen metabolites (ROMs) in a group of gasoline station attendants exposed to low-dose benzene and to evaluate the influence of antioxidant food intake on these biomarkers of oxidative stress. The diet adopted by the population examined consisted of compounds belonging to the classes of terpenoids, stilbenes and flavonoids, notably resveratrol, lycopene and apigenin. Ninety one gasoline station attendants occupationally exposed to benzene and 63 unexposed male office workers were recruited for this study. Urinary trans, trans-muconic acid (t,t-MA) concentration, determined to assess individual exposure level, resulted significantly higher in exposed workers. In subjects exposed to benzene, we observed a significant increase (p < 0.001) in ROMs and AOPP levels, which were also negatively correlated with fruit and vegetables consumption. By contrast, AGE did not show a significant increase and consequently any relation with antioxidant food intake. Only ROMs, representing a global biomarker of oxidative status, resulted correlated to t,t-MA levels (p < 0.01), probably due to low-dose exposure. Increase of ROS induced by reactive benzene metabolites may promote specific biochemical pathways with a major production of AOPP, which seem to represent a more sensitive biochemical marker of oxidative stress in workers exposed to benzene compared to AGE. Furthermore, this is the first study demonstrating ROMs increment in subject exposed to benzene. These biomarkers may be useful for screening purposes in gasoline station workers and other subjects exposed to low-dose benzene. Moreover, a diet rich in fruits and vegetables demonstrated an inverse association with the levels of oxidative stress markers, suggesting a protective role of antioxidant food intake in workers exposed to oxidant agents.

Abstract
Genomic instability can initiate cancer, augment progression, and influence the overall prognosis of the affected patient. Genomic instability arises from many different pathways, such as telomere damage, centrosome amplification, epigenetic modifications, and DNA damage from endogenous and exogenous sources, and can be perpetuating, or limiting, through the induction of mutations or aneuploidy, both enabling and catastrophic. Many cancer treatments induce DNA damage to impair cell division on a global scale but it is accepted that personalized treatments, those that are tailored to the particular patient and type of cancer, must also be developed. In this review, we detail the mechanisms from which genomic instability arises and can lead to cancer, as well as treatments and measures that prevent genomic instability or take advantage of the cellular defects caused by genomic instability. In particular, we identify and discuss five priority targets against genomic instability: (1) prevention of DNA damage; (2) enhancement of DNA repair; (3) targeting deficient DNA repair; (4) impairing centrosome clustering; and, (5) inhibition of telomerase activity. Moreover, we highlight vitamin D and B, selenium, carotenoids, PARP inhibitors, resveratrol, and isothiocyanates as priority approaches against genomic instability. The prioritized target sites and approaches were cross validated to identify potential synergistic effects on a number of important areas of cancer biology.

Abstract
BACKGROUND Long-term exposure to persistent pollutants with hormonal properties (endocrine-disrupting chemicals; EDCs) may contribute to the risk of prostate cancer (PCa). However, epidemiological evidence remains limited. OBJECTIVES We investigated the relationship between PCa and plasma concentrations of universally widespread pollutants, in particular p,p'-dichlorodiphenyl dichloroethene (DDE) and the non-dioxin-like polychlorinated biphenyl congener 153 (PCB-153). METHODS We evaluated 576 men with newly diagnosed PCa (before treatment) and 655 controls in Guadeloupe (French West Indies). Exposure was analyzed according to case-control status. Associations were assessed by unconditional logistic regression analysis, controlling for confounding factors. Missing data were handled by multiple imputation. RESULTS We estimated a significant positive association between DDE and PCa [adjusted odds ratio (OR) = 1.53; 95% CI: 1.02, 2.30 for the highest vs. lowest quintile of exposure; p trend = 0.01]. PCB-153 was inversely associated with PCa (OR = 0.30; 95% CI: 0.19, 0.47 for the highest vs. lowest quintile of exposure values; p trend < 0.001). Also, PCB-153 was more strongly associated with low-grade than with high-grade PCa. CONCLUSIONS Associations of PCa with DDE and PCB-153 were in opposite directions. This may reflect differences in the mechanisms of action of these EDCs; and although our findings need to be replicated in other populations, they are consistent with complex effects of EDCs on human health.

Abstract
Cofilin is a member of the actin-depolymerizing factor (ADF) family protein, which plays an essential role in regulation of the mitochondrial apoptosis. It remains unclear how cofilin regulates the mitochondrial apoptosis. Here, we report for the first time that natural compound 4-methylthiobutyl isothiocyanate (erucin) found in consumable cruciferous vegetables induces mitochondrial fission and apoptosis in human breast cancer cells through the mitochondrial translocation of cofilin. Importantly, cofilin regulates erucin-induced mitochondrial fission by interacting with dynamin-related protein (Drp1). Knockdown of cofilin or Drp1 markedly reduced erucin-mediated mitochondrial translocation and interaction of cofilin and Drp1, mitochondrial fission, and apoptosis. Only dephosphorylated cofilin (Ser 3) and Drp1 (Ser 637) are translocated to the mitochondria. Cofilin S3E and Drp1 S637D mutants, which mimick the phosphorylated forms, suppressed mitochondrial translocation, fission, and apoptosis. Moreover, both dephosphorylation and mitochondrial translocation of cofilin and Drp1 are dependent on ROCK1 activation. In vivo findings confirmed that erucin-mediated inhibition of tumor growth in a breast cancer cell xenograft mouse model is associated with the mitochondrial translocation of cofilin and Drp1, fission and apoptosis. Our study reveals a novel role of cofilin in regulation of mitochondrial fission and suggests erucin as a potential drug for treatment of breast cancer.

Abstract
Hydrogen sulfide (H2S) donors including organosulfur compounds (OSC), inorganic sulfide salts, and synthetic compounds are useful tools in studies to elucidate the effects of H2S in cancer biology. Studies using such donors have shown the ability of H2S to suppress tumor growth both in vitro and in vivo, with some of them suggesting the selectivity of its cytotoxic effects to cancer cells. In addition to promoting cancer cell death, H2S donors were also found to inhibit cancer angiogenesis and metastasis. The underlying mechanisms for the anticancer activities of H2S involve (1) cell signaling pathways, such as MAPK and STAT; (2) cell cycle regulation; (3) microRNAs regulation; and (4) cancer metabolism and pH regulation. Altogether, compiling evidences have demonstrated the great potential of using H2S donors as anticancer agents. Nevertheless, the application and development of H2S for therapy are still facing challenges as identification of molecular targets of H2S awaits further investigation.

Abstract
Background Prostate cancer is the second most common cause of cancer worldwide after lung cancer. There is increasing evidence that diet and lifestyle plays a crucial role in prostate cancer biology and tumourigenesis. Prostate cancer itself represents a good model of cancer in which to look for chemopreventive agents due to the high disease prevalence, slowly progressive nature, and long latency period. Dietary agents have gained considerable attention, often receiving much publicity in the media. Aim To review the key evidence available for potential chemopreventive nutrients. Methods The methodology for this review involved a PubMed search from 1990 to 2013 using the key-words “diet and prostate cancer”, “nutrition and prostate cancer”, “dietary factors and prostate cancer”, “prostate cancer epidemiology”, “prostate cancer prevention”, “prostate cancer progression”. Results Red meat, dietary fat and milk intake should be minimised as they appear to increase the risk of prostate cancer. Fruit and vegetables and polyphenols may be preventive in prostate cancer, but further studies are needed to draw more solid conclusions and to clarify their role in patients with an established diagnosis of prostate cancer. Selenium and vitamin supplements cannot be advocated for the prevention of prostate cancer and indeed higher doses may be associated with a worse prognosis. There is no specific evidence regarding benefits of probiotics or prebiotics in prostate cancer. Conclusions From the wealth of evidence available, many recommendations can be made although more randomised control trials are required. These need to be carefully designed due to the many confounding factors and heterogeneity of the population.

Abstract
Glucosinolates are the characteristic secondary metabolites of plants in the order Brassicales. To date the common DIN extraction 'desulfo glucosinolates' method remains the common procedure for determination and quantification of glucosinolates. However, the desulfation step in the extraction of glucosinolates from Moringa oleifera leaves resulted in complete conversion and degradation of the naturally occurring glucosinolates in this plant. Therefore, a method for extraction of intact Moringa glucosinolates was developed and no conversion and degradation of the different rhamnopyranosyloxy-benzyl glucosinolates was found. Buffered eluents (0.1 M ammonium acetate) were necessary to stabilize 4-α-rhamnopyranosyloxy-benzyl glucosinolate (Rhamno-Benzyl-GS) and acetyl-4-α-rhamnopyranosyloxy-benzyl glucosinolate isomers (Ac-Isomers-GS) during HPLC analysis. Due to the instability of intact Moringa glucosinolates at room temperature and during the purification process of single glucosinolates, influences of different storage (room temperature, frozen, thawing and refreezing) and buffer conditions on glucosinolate conversion were analysed. Conversion and degradations processes were especially determined for the Ac-Isomers-GS III.

[PMID: 24204579 PMCID: PMC3810374 DOI: 10.1371/journal.pone.0075732] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/25/2013] [Accepted: 08/16/2013] [Indexed: 01/20/2023] Open
Abstract
Background Epidemiologic studies have evaluated the association between cruciferous vegetables(CV) intake and the risk of renal cell carcinoma(RCC); however, the existing results are controversial. The aim of this meta-analysis was to investigate the association between CV intake and RCC risk. Methods A literature search was carried out using PUBMED and EMBASE database between January 1966 and March 2013. Fixed-effect and random-effect models were used to estimate summary relative risks (RR) and the corresponding 95% confidence intervals (CIs). Potential sources of heterogeneity were detected by meta-regression. Subgroup analyses, sensitivity analysis and cumulative meta-analysis were also performed. Results A total of 12 studies (six cohorts, six case–control) contributed to the analysis, involving 1,228,518 participants and 5,773 RCC cases. When all studies were pooled, we observed a significantly inverse association between CV intake and RCC risk (RR = 0.81, 95% CI [0.72, 0.91]). This association was also significant when analyses were restricted to six high-quality studies (RR = 0.89, 95% CI [0.82, 0.98]). In subgroup analyses, CV intake was significantly associated with reduced RCC risk among studies conducted in America (RR = 0.77, 95%CI [0.70, 0.86]); however, CV intake had no significant association with RCC risk among studies conducted in Europe (RR = 0.87, 95%CI [0.71, 1.07]). Furthermore, sensitivity analysis confirmed the stability of results. Conclusions The findings of this meta-analysis suggested that high intake of CV was inversely associated with RCC risk among Americans. More studies, especially high quality cohort studies with larger sample size, well controlled confounding factors are warranted to confirm this association.
