Abstract
PURPOSE Proton pump inhibitors (PPIs) inhibit fatty acid synthase (FAS), a critical enzyme in lipogenesis, energy balance, and cancer cell survival. We aimed to evaluate the association of PPI use with incidence of common obesity- related cancers in women: postmenopausal breast, colorectal, and endometrial cancers. METHODS Our study included 124,931 postmenopausal who were enrolled in the Women's Health Initiative (WHI) observational study and clinical trials, and had responded to a year 3 follow-up assessment. We examined prescription and over the counter use of PPI and/or histamine 2 receptor antagonists (H2RA) at baseline and year 3, to isolate potential effects of FAS inhibition by PPI rather than simply acid suppression. Incident cancer cases were physician-adjudicated. Cox proportional hazard regression models were used to estimate multivariable hazard ratios (HR) and 95% confidence intervals (CI) for associations between PPI and/or H2RA use and cancer incidence after year 3. RESULTS There were 7956 PPI ever users (with or without H2RA use) and 9398 H2RA only users. PPI or H2RA use was not associated with risk of breast cancer (n=9186 cases), compared to women who did not use either agent (HR 1.01, 95% CI 0.93-1.10 and HR 0.95 95% CI 0.87-1.03, respectively). The incidence of colorectal cancer (n=2280) was significantly lower in PPI users (HR 0.75, 95% CI 0.61-0.92), but not in H2RA users (HR 1.13, 95% CI 0.97-1.31). This association was strengthened with increasing duration (p=0.006) and potency (p=0.005) of PPI use and held regardless of BMI or NSAID use. PPI or H2RA use was not associated with endometrial cancer (n=1231) (HR 0.81, 95% CI 0.61-1.07 and HR 1.13, 95% CI 0.91-1.40, respectively), but showed a trend in decreased risk with increasing PPI potency (P=0.048). CONCLUSIONS Among postmenopausal women, PPI use, but not H2RA use, demonstrated an inverse, dose-responsive association with colorectal cancer incidence. This was consistent with preclinical data that FAS inhibition prevents colon cancer progression and supports further investigation of this commonly used medication as a cancer preventive agent. PPI use was not associated with incidence of breast or endometrial cancer.

Abstract
Excess adiposity is a risk factor for several cancer types. This is likely due to complex mechanisms including alterations in the lipid milieu that plays a pivotal role in multiple aspects of carcinogenesis. Here we consider the direct role of lipids in regulating well-known hallmarks of cancer. Furthermore, we suggest that obesity-associated remodelling of membranes and organelles drives cancer cell proliferation and invasion. Identification of cancer-related lipid-mediated mechanisms amongst the broad metabolic disturbances due to excess adiposity is central to the identification of novel and more efficacious prevention and intervention strategies.

Abstract
BACKGROUND There has been little research published on the adaptation of diabetic exchange list diet approaches for the design of intervention diets in health research despite their clinical utility. The exchange list approach can provide clear and precise guidance on multiple dietary changes simultaneously. The present study aimed to develop exchange list diets for Mediterranean and Healthy Eating, and to evaluate adherence, dietary intakes and markers of health risks with each counselling approach in 120 subjects at increased risk for developing colon cancer. METHODS A randomised clinical trial was implemented in the USA involving telephone counselling. The Mediterranean diet had 10 dietary goals targeting increases in mono-unsaturated fats, n-3 fats, whole grains and the amount and variety of fruits and vegetables. The Healthy Eating diet had five dietary goals that were based on the US Healthy People 2010 recommendations. RESULTS Dietary compliance was similar in both diet arms, with 82-88% of goals being met at 6 months, although subjects took more time to achieve the Mediterranean goals than the Healthy Eating goals. The relatively modest fruit and vegetable goals in the Healthy Eating arm were exceeded, resulting in fruit and vegetable intakes of approximately eight servings per day in each arm after 6 months. A significant (P < 0.05) weight loss and a decrease in serum C-reactive protein concentrations were observed in the overweight/obese subgroup of subjects in the Mediterranean arm in the absence of weight loss goals. CONCLUSIONS Counselling for the Mediterranean diet may be useful for both improving diet quality and for achieving a modest weight loss in overweight or obese individuals.

Abstract
AIMS/HYPOTHESIS We hypothesised that diabetic patients would differ from those without diabetes in regard to the handling of glucose-derived reactive metabolites, evidenced by triosephosphate intermediates (TP(INT)) and methylglyoxal (MG), irrespective of the type of diabetes, plasma glucose level or HbA(1c) value. METHODS To test this hypothesis, erythrocytes were isolated from patients with type 1 (n = 12) and type 2 (n = 12) diabetes with varying blood glucose and HbA(1c) levels. These were then compared with erythrocytes isolated from individuals without diabetes (n = 10), with respect to MG, as determined by HPLC, and TP(INT), as determined by endpoint enzymatic assays. RESULTS The concentrations of intracellular TP(INT) and MG were significantly elevated in erythrocytes from diabetic patients. Normalisation of either TP(INT) or MG to intracellular glucose concentration (nmol glucose/mgHb) confirmed that erythrocytes from diabetic patients accumulated more reactive metabolites than did those from healthy controls. CONCLUSIONS/INTERPRETATION Diabetic patients can be characterised by an increased formation of TP(INT) and MG. The 25-fold increase of MG in type 1 and the 15-fold increase in type 2 diabetes, together with a several-fold increase in TP(INT) and decreased glyceraldehyde-3-phosphate dehydrogenase activity even under normal glucose conditions, imply that normalising glucose level cannot completely prevent late diabetic complications until this acquired error of metabolism has been restored.

Abstract
The receptor for glycation end-products RAGE was previously shown to play a central role in the development of diabetic neuropathy. The present study was aimed to investigate, whether plasma levels of the soluble forms of RAGE are associated with neuropathy in type 2 diabetes. One-hundred and eight patients were screened for peripheral and autonomic diabetic neuropathy using standardized screening tests. No differences in the levels of soluble RAGE or the more defined endogenous secretory RAGE were observed in patients categorized into having no, mild, moderate, or severe deficits in the neuropathy disability or symptom score. In bivariate analysis, neither soluble RAGE nor endogenous secretory RAGE correlated with the expiration to inspiration ratio of heart rate variability. In multivariate models, the neuropathy disability score was independently associated with age (beta=0.38, p<0.01), glomerular filtration rate (beta=0.28, p<0.01) and the presence of retinopathy (beta=0.27, p<0.01), while the neuropathy symptom score was associated with age (beta=0.31, p<0.01) and fasting glucose (beta=0.24, p<0.05). The expiration to inspiration ratio of heart rate variability was associated with age (beta=-0.42, p<0.01), the body-mass-index (beta=-0.28, p<0.01) and presence of retinopathy (beta=-0.19, p<0.05). In contrast to classical risk factors, plasma soluble RAGE and endogenous secretory RAGE are not associated with measures of diabetic neuropathy in type 2 diabetes patients.

Abstract
BACKGROUND AND OBJECTIVE Patients on hemodialysis exhibit a drastically increased cardiovascular mortality. Inflammation, hyperphosphatemia and lack of calcification inhibitors are uremia-associated risk factors for vascular calcification. Functional and morphological vascular parameters are used to assess cardiovascular risk. The aim of our study was to analyse the relation between pulse wave velocity (PWV) and intima-media-thickness (IMT) with calcification inhibitors. METHODS A cohort of 97 hemodialysis patients was consecutively selected and investigated (age 56 +/- 9 years). Carotid-femoral PWV, carotid IMT, left ventricular ejection fraction and septum thickness were determined. These parameters were correlated with serum levels of CRP and calcification inhibitors (fetuin-A and osteoprotegerin [OPG]). RESULTS Both PWV and IMT showed a positive correlation with age and systolic blood pressure and a negative correlation with Kt/V (dialysis efficiency). Additionally, fetuin-A was negatively associated with CRP and positively with cholesterol and triglycerides. Serum levels of the calcification inhibitors fetuin-A and OPG were not correlated to PWV or IMT. CONCLUSION The lack of correlation of calcification inhibitors with PWV and IMT means that functional and morphological measurements of vascular properties can not necessarily be replaced by analysing "biomarkers".

Abstract
Thiazolidinediones such as pioglitazone have been shown to exert anti-inflammatory effects independent of their insulin sensitizing effects by reducing activation of the proinflammatory transcription factor NF-kappaB in animal models of experimental diabetes. Furthermore, short-term pioglitazone treatment ameliorates endothelial dysfunction in conduit arteries of patients with type 2 diabetes. Since inflammation is supposed to impair flow-mediated vasodilatation, we studied the effects of an 8-week pioglitazone intervention on endothelial function and mononuclear NF-kappaB activation in patients with type 2 diabetes. Twenty patients were included in a randomized, double-blind, placebo-controlled study receiving 30 mg pioglitazone or placebo, respectively. Flow-mediated endothelium dependent vasodilatation (FMD) of the brachial artery, NF-kappaB binding activity in peripheral blood mononuclear cells [pBMC, determined by electrophoretic mobility shift assay (EMSA)] and interleukin-6 (IL-6)-transcription rates (determined by real-time PCR) were measured at study entry and after eight weeks of intervention. Pioglitazone treatment resulted in a significant improvement of FMD (4.3%+/-3.3; p=0.003), while no effect was seen under placebo medication (2.0%+/-2.7; p=0.71). The correction of FMD was neither paralleled by a pioglitazone-dependent reduction in mononuclear NF-kappaB binding activity (DeltaNF-kappaB activity: pioglitazone: 9.2%+/-6.7, p=0.24; placebo: 5.7%+/-19.6; p=0.82) nor in NF-kappaB dependent gene transcription as determined for IL-6 (DeltaIL-6 pioglitazone: +1.8%+/-12.0, p=0.93; placebo: -0.2%+/-9.7; p=0.92). These data demonstrate for the first time that pioglitazone treatment improves endothelial dysfunction in patients with type 2 diabetes without affecting NF-kappaB binding activity and NF-kappaB dependent proinflammatory gene expression in pBMC.

Abstract
AIMS/HYPOTHESIS The p75 neurotrophin receptor (p75NTR) has been shown to appear in the plasma of diabetic rats, possibly indicating diabetic neuropathy. The aim of this study was to use a semi-quantitative assay for human plasma p75NTR to investigate whether this receptor is a marker of peripheral diabetic neuropathy (DPN) and autonomic cardiovascular neuropathy (CAN) in type 2 diabetic patients. SUBJECTS AND METHODS Eighty type 2 diabetic patients and 25 controls without diabetes were analysed for p75NTR immunoreactivity by western blot analysis. DPN was assessed using the Neuropathy Disability Score (NDS). Cardiovascular autonomic function was detected using a standardised analysis of heart rate variability. RESULTS Three distinct p75NTR signals were detectable in human plasma at approximately 75, approximately 51 and approximately 24 kDa, representing the full length receptor (FL) and its intracellular domain (ICD) and extracellular domain (ECD), respectively. Levels of total plasma p75NTR immunoreactivity in patients with type 2 diabetes were similar to those in controls. Type 2 diabetic patients had significantly higher plasma levels of ICD and lower levels of ECD. However, there were no correlations of total p75NTR immunoreactivity or ECD or ICD immunoreactivity with NDS or aspects of CAN. CONCLUSIONS/INTERPRETATION Levels of the ECD of p75NTR are reduced and levels of the ICD are increased in the plasma of type 2 diabetic patients. None of the p75NTR subunits identified in human plasma seem to be a marker of peripheral or autonomic neuronal function in patients with type 2 diabetes.

Abstract
The food frequency questionnaire (FFQ) is commonly utilized for assessment of dietary fat intake, but its validity among individuals following a low-fat diet is unclear. We evaluated the agreement of nutrient estimates derived from FFQ, 24-h recall, and 3-day food records obtained from 104 participants in a randomized trial of a low-fat dietary intervention for women at elevated breast cancer risk. Comparisons were made for total calories, percent calories from fat, and total fat after 1 yr. Correlation was assessed using standard methods based on a null hypothesis of no agreement between instruments as well as by a methodology based on a null hypothesis that the instruments should be in agreement. With the use of standard methods, FFQ estimates for women on the low-fat diet were significantly correlated to records only for percent calories from fat (r = 0.39), whereas recall and record estimates were significantly correlated for all three dietary variables. Using the new method, we found no significant correlation between FFQ and either recalls or records for women following a low-fat diet but significant correlation between recall and record estimates for total calories (r = 0.67). Traditional correlation testing may overestimate the extent of agreement in dietary instruments among women on a low-fat diet. We found empirical support for the nontraditional method.

Abstract
BACKGROUND Dietary intervention research with free-living subjects relies on the ability of study participants to meet their dietary goals within the study timeframe. Little is known about underlying factors affecting compliance. METHOD Here, we examined whether motivation to enroll in a trial of low-fat and/or energy-reduced diets influenced the ability of healthy women to reach their dietary goals quickly. RESULTS Of the women who had energy-reduction goals (n=43), the 18 with an altruistic reason for participation had a much higher energy reduction success rate at 4 weeks (83%) than the 25 who gave self-rewarding reasons (48%). CONCLUSIONS Education, body weight, family history of cancer and previous diet experience did not appreciably affect dietary outcomes. This observation suggests that the societal importance of the research should be stressed in strategies that seek to affect rapid reduction of energy intake in clinical trials.

Abstract
Dietary fat has previously been shown to have somewhat complicated relationships to levels of oxidative stress in rats. In this study, we examined the effects of five different dietary fat intakes on levels of oxidative DNA damage in rats. Animals fed diets containing 3%, 5%, 10%, or 15% corn oil had body weights that were similar after 20 weeks. Animals fed a 20% fat diet, however, had significantly higher mean body weight than any other group. Levels of 5-hydroxymethyl-2'-deoxyuridine, one marker of oxidative DNA damage, had different relationships to dietary fat in blood and mammary gland. In blood, levels increased with dietary fat levels, and the highest levels were observed with the 20% fat diet (65% higher levels than with the 3% fat diet). In mammary gland, a plateau-type effect was observed, with maximal levels of oxidative DNA damage being obtained using 10% fat (representing a 68% increase relative to the 3% fat diet). This could be a result of induction of compensatory mechanisms in response to a high-fat diet in mammary gland but not in the short-lived nucleated blood cells. Oxidative DNA damage levels in blood thus appear to be a marker of dietary fat intake. In mammary gland, however, levels of DNA damage are consistent with previously observed promotional effects of dietary fat on mammary gland tumorigenesis at lower levels of fat intake with little or no incremental promoting effects at higher levels of fat intake.

Abstract
Dietary intake of soy has been linked with decreased cancer risk, and the active compounds in soy that have been identified include the isoflavones genistein and daidzein. Since these compounds have antioxidant properties, we examined levels of oxidative damage in blood of six women and six men before and during soy supplementation using Novasoy tablets. Blood samples were obtained at weekly intervals for 3 weeks from the women taking 50-mg isoflavones once daily and the men taking 50-mg isoflavones twice daily. Plasma levels of genistein and daidzein increased after supplementation with maximal levels occurring at 2 weeks for the women while levels in men kept increasing over the 3 weeks of study. There was wide variation between individuals in the levels of isoflavones achieved. Mean levels of 5-hydroxymethyl-2'-deoxyuridine (5-OHmdU) in DNA from nucleated blood cells decreased after 1 week of supplementation in the women, with a decrease of 47% in mean 5-OHmdU levels after 3 weeks. In men, mean 5-OHmdU levels did not decrease until after 3 weeks of supplementation, at which there was 61% decrease. Mean plasma levels of 8-isoprostanes were not changed appreciably in either men or women. These pilot results suggest that soy isoflavone supplementation decreases levels of oxidative DNA damage in humans, and this may be a mechanism behind the cancer-preventive effects of soy isoflavones.

Abstract
It has been questioned whether carotenoids can act as antioxidants in biological membranes. Biological membranes can be modeled for studies of lipid peroxidation using unilamellar liposomes. Both carotenoid depletion and lipid peroxidation were increased with increasing oxygen tension in unilamellar liposomes. Carotenoids in such liposomes were found to be very sensitive to degradation by free radicals generated from iron and 2,2'-azobis(2-amidinopropane) dihydrochloride, but they were not protective against lipid peroxidation. Lycopene and beta-carotene were more sensitive to free radical attack than lutein, zeaxanthin, and beta-cryptoxanthin.

Abstract
An inverse association has been observed between dietary intake of lycopene and the risk of prostate cancer. We investigated the effects of lycopene supplementation in patients with prostate cancer. Twenty-six men with newly diagnosed, clinically localized (14 T(1) and 12 T(2)) prostate cancer were randomly assigned to receive 15 mg of lycopene (n = 15) twice daily or no supplementation (n = 11) for 3 weeks before radical prostatectomy. Biomarkers of differentiation and apoptosis were assessed by Western blot analysis on benign and malignant parts of the prostate gland. Prostatectomy specimens were entirely embedded, step-sectioned, and evaluated for pathological stage, Gleason score, volume of cancer, and extent of high-grade prostatic intraepithelial neoplasia. Plasma levels of lycopene, insulin-like growth factor-1 (IGF-1), IGF binding protein-3, and prostate-specific antigen were measured at baseline and after 3 weeks of supplementation or observation. Eleven (73%) subjects in the intervention group and two (18%) subjects in the control group had no involvement of surgical margins and/or extra-prostatic tissues with cancer (P = 0.02). Twelve (84%) subjects in the lycopene group and five (45%) subjects in the control group had tumors <4 ml in size (P = 0.22). Diffuse involvement of the prostate by high-grade prostatic intraepithelial neoplasia was present in 10 (67%) subjects in the intervention group and in 11 (100%) subjects in the control group (P = 0.05). Plasma prostate-specific antigen levels decreased by 18% in the intervention group, whereas they increased by 14% in the control group (P = 0.25). Expression of connexin 43 in cancerous prostate tissue was 0.63 +/- 0.19 absorbance in the lycopene group compared with 0.25 +/- 0.08 in the control group (P = 0.13). Expression of bcl-2 and bax did not differ significantly between the two study groups. IGF-1 levels decreased in both groups (P = 0.0002 and P = 0.0003, respectively). The results suggest that lycopene supplementation may decrease the growth of prostate cancer. However, no firm conclusions can be drawn at this time because of the small sample size.

Abstract
Lipid and DNA oxidation catalyzed by iron(II) were compared in HEPES and phosphate buffers. Lipid peroxidation was examined in a sensitive liposome system constructed with a fluorescent probe that allowed us to examine the effects of both low and high iron concentrations. With liposomes made from synthetic 1-stearoyl-2-linoleoyl-sn-glycero-3-phosphocholine or from rat liver microsomal lipid, lipid peroxidation increased with iron concentration up to the range of 10--20 microM iron(II), but then rates decreased with further increases in iron concentration. This may be due to the limited amount of lipid peroxides available in liposomes for oxidation of iron(II) to generate equimolar iron(III), which is thought to be important for the initation of lipid peroxidation. Addition of hydrogen peroxide to incubations with 1--10 microM iron(II) decreased rates of lipid peroxidation, whereas addition of hydrogen peroxide to incubations with higher iron concentrations increased rates of lipid peroxidation. Thus, in this liposome system, sufficient peroxide from either within the lipid or from exogenous sources must be present to generate equimolar iron(II) and iron(III). With iron-catalyzed DNA oxidation, hydrogen peroxide always stimulated product formation. Phosphate buffer, which chelates iron but still allows for generation of hydroxyl radicals, inhibited lipid peroxidation but not DNA oxidation. HEPES buffer, which scavenges hydroxyl radicals, inhibited DNA oxidation, whereas lipid peroxidation was unaffected since presumably iron(II) and iron(III) were still available for reaction with liposomes in HEPES buffer.

Abstract
Dietary intake of soy has been associated with a decreased risk of cancer. Soy isoflavones have been postulated to be the protective compounds in soybeans; however, the precise mechanism by which soy isoflavones prevent human cancer is not known. The major soy isoflavones, genistein and daidzein, are antioxidant compounds, therefore one possible mechanism of action is through their antioxidant effect. We have previously demonstrated that the soy isoflavone, genistein, inhibits the activation of the redox-sensitive transcription factor, NF-kappa B, in prostate cancer cells in vitro. In this study, we have demonstrated that genistein, but not daidzein, inhibits TNF-alpha-induced NF-kappa B activation in cultured human lymphocytes. Additionally, we investigated the in vivo effect of soy isoflavone supplementation on NF-kappa B activation induced by TNF-alpha in vitro in peripheral blood lymphocytes of six healthy men. We show that healthy male subjects receiving 50 mg isoflavone mixture (Novasoy) twice daily for 3 weeks are protected from TNF-alpha induced NF-kappa B activation. Additionally, we observed a reduction of 5-hydroxymethyl-2'-deoxyuridine (5-OHmdU), a marker for oxidative DNA damage, following isoflavone supplementation. The inhibitory effect of soy isoflavones was no longer present 3 months after the supplementation. This preliminary study demonstrates that soy isoflavone supplementation may protect cells from oxidative stress-inducing agents by inhibiting NF-kappa B activation and decreasing DNA adduct levels.

Abstract
Increased consumption of tomatoes and tomato products has been associated with decreased cancer risks. One fat-soluble compound identified in tomatoes which may be responsible for this association is lycopene. There may, however, be other antioxidants present in tomato-based foods, and total antioxidant capacity may be another way to rate the health benefits of these foods. In this work, we examined the Trolox-equivalent antioxidant capacity (TEAC) of aqueous and organic extracts of lycopene-containing foods: ketchup, fresh tomatoes, tomato paste, tomato sauce, tomato soup, tomato juice, vegetable juice, canned tomatoes and watermelon. Antioxidant activity in these food extracts was greater in the aqueous versus organic fractions, except for watermelon and tomato sauce where the levels were similar in the two fractions. Lycopene levels in the food samples tested, however, were relatively greater in the organic fractions, with the exception of the two juices, which had similar levels in the two fractions, and two highly concentrated tomato products, tomato paste and ketchup, which had relatively higher lycopene levels in the aqueous fractions. The foods with the highest antioxidant capacity per serving overall (tomato soup was highest) did not have the highest lycopene levels. This indicates that it may be important to consume a variety of tomato-containing products in order to obtain the largest variety of dietary antioxidants possible.

Abstract
Systemic oxidative stress is thought to contribute to risk of various cancers, including breast cancer. DNA repair ability also has been associated with breast cancer risk. In this work, we examined levels of oxidative DNA damage as an indication of breast cancer risk in women because oxidative DNA damage levels should reflect the net balance of oxidative stress and DNA repair ability. Levels of 5-hydroxymethyl-2'-deoxyuridine, one form of oxidative DNA damage, were measured in DNA from blood of women scheduled for breast biopsy. The blood samples analyzed included women whose biopsy results indicated invasive breast cancer, high-risk lesions (atypical hyperplasia or carcinoma in situ), or benign lesions. Mean levels of 5-hydroxymethyl-2'-deoxyuridine were significantly higher in blood of women who had high risk or invasive breast lesions versus women with benign lesions. If atypical hyperplasia or carcinoma in situ are precursor lesions for breast cancer, then these results suggest that oxidative DNA damage may be involved in the cancer process before invasive cancer develops.

Abstract
We present an experimental verification of the semiclassical theory for static conductivity calculations in the case of moderately nonideal plasmas. Such plasmas are produced in linear flashlamps filled with pure helium and are characterized by on axis electron densities in the range 2x10(17)-1.7x10(18) cm(-3) and temperatures (2-3)x10(4) K. Precise measurements of the discharge electrical parameters have been carried out and in each case the impedance of the plasma was compared with the calculated value using the semiclassical theory, which is a simpler approximation than the quantum-mechanical theory based on the random-phase approximation.

Abstract
Oxidative DNA damage (ODD) can result from numerous endogenous metabolic processes as well as from exposure to environmental and dietary oxidants. One important type of ODD that may have a role in carcinogenesis is the formation of hydroxylated DNA bases. Our major purpose was to determine the potential for subject accrual for a multisite case-control study of ODD and breast cancer risk within a large urban university medical center. We examined the levels of a hydroxylated thymine residue, 5-hydroxymethyl-2'-deoxyuridine in DNA obtained from the peripheral blood of 26 women with breast cancer and an age-matched group of 29 control women without breast cancer. The isolated DNA was analyzed for levels of 5-hydroxymethyl-2'-deoxyuridine by gas chromatography with mass spectral detection. Our recruitment methods resulted in a relatively high yield of eligible cases (72%) and a lower yield of controls (46%). We evaluated the dose-response relationship of ODD level to breast cancer risk, using quartiles of ODD. The covariate-adjusted odds ratio of breast cancer exceeded 2.0 for women in the highest quartile of ODD (compared with the lowest quartile), although this result was not statistically significant. ODD levels were significantly more variable among African-American controls (SD = 224.1) than among white controls (SD = 57.5), p < 0.001. Overall, these results suggest a possible slight increase in breast cancer risk among women in the highest ODD quartile, after adjusting for race, menopausal status, and family history of breast cancer.

Abstract
The effects of dietary fat and age on the level of malondialdehyde (MDA), a product of lipid peroxidation, were investigated in cerebellum, kidney, and liver tissues of female Fischer 344 rats. Groups of rats were fed diets containing various levels of corn oil (3, 5, 10, 15, or 20%), starting at 57 days of age, for a duration of 2, 10, or 20 weeks. High fat diets are thought to promote tumor formation, diabetes, and cardiovascular diseases via induction of oxidation stress, and this can begin early in the lifespan. However, it was observed that rats chronically consuming 3 and 5% corn oil diets yielded significantly higher levels of MDA, as analyzed by high-performance liquid chromatography, compared with those fed higher fat diets. After 20 weeks of feeding, the concentration of MDA in each of the three organs studied showed no significant differences among rats consuming diets containing 10, 15, or 20% corn oil. The levels of MDA were highest in the cerebellum, followed by kidney, and lowest in liver. Over the 20-week feeding period, a decrease in MDA level in both cerebellum and liver was observed.

Abstract
Dietary fat and energy intake have been implicated in breast cancer etiology. To examine the relative importance of these dietary factors on markers of cancer risk in women, we designed an intervention trial to selectively decrease fat and/or energy intake in free-living, premenopausal women who were somewhat overweight. The study used a 2 x 2 factorial design to evaluate the independent and interactive effects of dietary fat and energy. The diets were nonintervention, low fat (15% of energy from fat, maintenance of energy intake), low energy (25% energy reduction), and combination low fat and low energy. We utilized an individualized counseling approach with self-selection of foods. Women on the low-fat and combination diets were asked to meet given daily goals for fat grams and food group exchanges, while women on the low-energy diet used only food group exchanges. Of the 113 premenopausal women randomized who were eligible for analysis, 43% were African-American. A total of 88 women completed the 12-week program, and adherence to the dietary goals was similar in both racial groups. Women on the low-fat diet were able to reduce dietary fat intake to 19% of energy by 4 weeks and to 17% by 12 weeks with a slight decrease in energy intake. Women on the low-energy diet met their energy reduction goals by four weeks while maintaining percentage of energy from fat. Women on the combination diet largely met their goals by four weeks as well. These data indicate that it is possible to selectively manipulate dietary fat and energy intake in women over a short period of time, which makes clinical studies on the relative effects of these two dietary variables on cancer risk biomarkers readily feasible.

Abstract
OBJECTIVE We examined the relationship between intakes of specific foods--namely, meats, vegetables, and fruits--with levels of oxidative DNA damage in women consuming their own usual diet or a diet low in fat. DESIGN Blood was obtained from women who had been assigned randomly to a low-fat or nonintervention diet for 3 to 24 months. Levels of 5-hydroxymethyluracil, a type of oxidative DNA damage, were determined. Diet data were obtained from 3-day food records. SUBJECTS/SETTING The 21 women were participating in an outpatient clinic. All the women were healthy but had a first-degree relative with breast cancer. INTERVENTION The intervention was a self-selected diet with a goal of 15% of energy from fat. MAIN OUTCOME MEASURES Existing data on oxidative DNA damage levels were evaluated for possible relationships to foods eaten. Intakes of raw and cooked vegetables were examined separately. Meat intake was examined by type of meat (pork, beef, fish, chicken) and by cooking temperature. STATISTICAL ANALYSES Initial univariate analyses relied on Spearman rank correlations of each food item with DNA damage. Further analyses of the data were performed with univariate and multivariate weighted least squares regression models. RESULTS The model that best explained DNA damage levels was a bivariate regression model that included the intake of cooked vegetables and the sum of beef and pork intake. This model accounted for 85% of the variation in DNA damage levels among women. Preliminary results are suggestive of a positive association of DNA damage with beef and pork intake and a negative association with cooked vegetable intake. APPLICATION These observations, if confirmed in larger studies, suggest specific dietary changes to reduce oxidative DNA damage levels and possibly cancer risk.

Abstract
Oxidative DNA damage levels may be a marker of breast cancer risk that is modulated by diet. We examined the effects of a high-fat diet fed in varying feeding regimens on levels of 5-hydroxymethyl-2'-deoxyuridine (5-OHmU), an oxidized thymidine residue, in DNA from mammary gland of aging female rats. A total of 48 rats were randomly divided into four groups: ad libitum fed (AL), weight cycled above baseline (WC-G), weight cycled below baseline (WC-L), or energy restricted (ER) for 28 weeks. WC groups were fed repeated ad libitum/restricted amounts of the diet. At sacrifice, both WC groups had body weights similar to the ER group but higher levels of 5-OHmU (p < 0.01). 5-OHmU levels were higher in the WC groups than in the AL group, even though body weights of the WC groups were significantly lower (p < 0.001). These results indicate that a history of weight cycling, even when body weight is reduced, can have adverse effects on 5-OHmU levels in mammary gland DNA, a potential biomarker of cancer risk. Constant control of calories for the maintenance of body weight, therefore, may be more beneficial.

Abstract
Flow cytometric analysis of nucleoids is useful to investigate nuclear matrix-DNA associations in cells. We have now applied this technique to examine whether differences in nucleoid structure can be detected between tumor and normal-like human breast epithelial cells. We have previously shown that MCF-7 tumor and MCF-10A normal-like human breast cells exhibit different levels of endogenous oxidative DNA damage as well as differences in response to hydrogen peroxide. We therefore examined whether flow cytometric analysis of nucleoids can be used to detect both endogenous DNA damage and DNA damage induced by hydrogen peroxide in these cells. Nucleoids were prepared by lysis of MCF-7 and MCF-10A cells with a high-salt buffer. The size of the DNA loops around the nuclear matrix core was detected by measuring the forward light-scatter signal in the presence of ethidium bromide. The relaxation and supercoiling of DNA in the presence of low and high concentrations of ethidium bromide, respectively, was similar in MCF-7 tumor and MCF-10A normal-like cells. After treatment of cells with 100 microM and higher of hydrogen peroxide, there was a statistically significant increase in the forward light scatter from nucleoids prepared in the presence of high concentrations of ethidium bromide, and this increase was similar in both cell lines. The changes in the forward light scatter signal with increasing hydrogen peroxide concentration did not mimic the patterns of increases in single strand breaks or formation of 5-hydroxymethyl-2 '-deoxyuridine that we reported previously. This indicates that the flow cytometric technique probably detects other types of changes induced by hydrogen peroxide.

Abstract
The growth inhibitory properties of alpha-tocopheryl hemisuccinate (vitamin E succinate) and related compounds were examined in MCF-7 human breast tumor cells and MCF-10A normal-like human breast cells since they have been suggested to be an effective antitumor compound. The data showed that both alpha-tocopherol hemisuccinate and a structurally-similar compound, cholesteryl hemisuccinate, inhibited the growth of MCF-7 and MCF-10A cells, while alpha-tocopherol, cholesterol, cholesteryl sulfate and Tris succinate had little effect on cell growth. The ether analogs of the succinate esters, alpha-tocopheryloxybutyric acid and cholesteryloxybutyric acid, also inhibited growth of MCF-7 and MCF-10A cells, indicating that hydrolysis of the succinate esters by esterases is not required for the antiproliferative effects. The antiproliferative effects of these succinate esters and ethers may be related to their physiochemical properties that allow incorporation into cell membranes.

One important type of oxidative DNA damage is the formation of hydroxylated DNA bases. This type of DNA damage may have a role in carcinogenesis. METHODS We examined the levels of a hydroxylated thymine residue, 5-hydroxy-methyl-2'-deoxyuridine, in DNA obtained from the peripheral blood of breast cancer patients and control women. The isolated DNA was analyzed for levels of 5-hydroxymethyl-2'-deoxyuridine by gas chromatography with mass spectral detection. RESULTS The levels of this modified base were significantly higher in 25 breast cancer patients compared with 38 controls, with levels of 0.112 +/- 0.046 in the cancer patients versus 0.083 - 0.025 in the controls, given as pg 5-hydroxymethyl-2'-deoxyuridine/ng thymidine, mean +/- standard deviation (P = 0.019). After controlling for various covariates, the adjusted mean levels of oxidative DNA damage were still significantly higher in women with breast cancer relative to controls. CONCLUSIONS These results indicate that the levels of 5-hydroxymethyl-2'-deoxyuridine in DNA from peripheral nucleated blood may be potentially useful as a marker of breast cancer.

Abstract
The in vitro testing of antitumor drugs involves the use of mouse and human tumor cells. In particular, there is interest in developing agents active against human solid tumors. We examined several biochemical parameters that may contribute to the differential sensitivity of the cell lines used in our laboratory to the toxic effects of antitumor compounds. The tumor cell lines examined were of mouse (colon 38, L1210 leukemia, and C1498 leukemia) and human origin (CEM leukemia, CX1 colon, H116 colon, HCT8 colon and H125 lung). Quinone reductase activity was markedly different between leukemia and solid-tumor cell lines of either mouse or human origin, with increased activity being observed in the solid-tumor cell lines relative to the leukemia lines. GSH transferase activity also was generally increased in solid-tumor relative to leukemia cell lines. Superoxide dismutase activity and thiol levels were similar in leukemia and solid-tumor cell lines, except that thiol levels were very low in colon 38. Mouse cell lines from in vitro passage had somewhat higher activity of superoxide dismutase and thiol levels than did cells maintained in vivo, indicating relatively increased antioxidant defenses. The toxicity of 2,3-dimethoxy-1,4-naphthoquinone, a model quinone that exerts its toxic effects via production of reactive oxygen species, was significantly lower in mouse lines maintained in vitro than in those tested in vivo, whereas the toxicity of another quinone, menadione, was just slightly lower. Quinone reductase activity, GSH transferase activity, and thiol levels were significantly higher in the human lines than in the mouse lines. Accordingly, the toxicity of both quinones tended to be lower in the human lines than in the mouse lines.

Abstract
In the present study we have established that the antitumor activity of alpha-tocopheryl succinate (TS, vitamin E succinate) and cholesteryl succinate (CS) result from the action of the intact TS and CS compounds and not from the release of alpha-tocopherol, cholesterol, or succinate. We report that treatment of murine leukemia cell lines C1498 (myeloid) and L1210 (lymphocytic), with the tris salts of TS or CS, but not alpha-tocopherol and tris succinate or cholesterol and tris succinate, significantly inhibit the growth of these tumor cells and significantly enhance doxorubicin-induced tumor cell kill in a similar fashion. In contrast, the treatments mentioned above did not adversely affect the growth of murine normal bone marrow cells (colony-forming unit-granulocyte-macrophage). In fact, colony-forming unit granulocyte-macrophage cell growth was stimulated by exposure to CS and TS (as well as their ether analogues) at concentrations above 100 microM. Furthermore, pretreatment of colony-forming unit granulocyte-macrophage cells with TS or CS appears to protect these normal cells from the lethal effect of doxorubicin exposure. Selective inhibition of leukemia cell proliferation (identical to that noted for CS and TS) was also observed following the treatment of cells with the nonhydrolyzable ether forms of CS (cholesteryloxybutyric acid) and TS (alpha-tocopheryloxybutyric acid). These findings suggest that TS, alpha-tocopheryloxybutyric acid, CS, and cholesteryloxybutyric acid may prove clinically useful as selective antitumor agents when administered alone or in combination with doxorubicin by a route that ensures tissue accumulation of the intact compound.

Abstract
Decreased dietary intake of fat and/or calories generally results in a lower incidence of mammary gland tumors in rodents. Feeding of either low-fat or calorie-restricted diets to rats also has been shown to result in decreased levels of oxidative DNA damage. Since oxidative DNA damage is suggested to have a role in carcinogenesis, this may be one mechanism by which dietary change can reduce cancer risk. The effects of calorie-restricted diets on both oxidative DNA damage levels and mammary gland tumor incidence are generally more pronounced than that of low-fat diets. There is, however, some difficulty in defining what amount of fat should be used to prepare 'low-fat' and 'high-fat' rodent diets as well as what a suitable fat intake for control diets should be in studies that examine the effects of dietary fat and/or calories on tumorigenesis. In particular, the promoting effects of dietary fat may be exerted only up to a certain level of fat, above which no further effect is observed. Another difficulty in the interpretation of the results is that there may be a time-dependent effect of high fat diets on oxidative damage, with increased damage resulting only when the diets are fed for longer periods of time. The appropriate experimental approach to model human dietary exposures therefore remains to be determined. Although the effects of caloric intake on mammary gland tumorigenesis appear to be more pronounced than that of fat intake, low-fat diets still may be useful as a preventive measure in human populations to reduce breast cancer risk for individuals who cannot safely reduce their caloric intake.
