      • Prostate-Specific Antigen Levels in Relation to Background Factors: Are there Links to Endocrine Disrupting Chemicals and AhR Expression?

        Bidgoli, Sepideh Arbabi,Jabari, Nasim,Zavarhei, Mansour Djamali Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.15

        Background: Prostate-specific antigen (PSA) is a potential biomarker for early detection of prostate cancer (PCa) but its level is known to be affected by many background factors and roles of ubiquitous toxicants have not been determined. Endocrine disrupting chemicals (EDCs) are ubiquitous reproductive toxicants used in consumer products, which promote tumor formation in some reproductive model systems by binding to AhR, but human data on its expression in prostate cancer as well as its association with PSA levels are not clear. This study aimed to evaluate the expression levels of AhR and its association with serological levels of PSA and to detect possible effects of background factors and EDC exposure history on PSA levels in PCa cases. Materials and Methods: A cross-sectional study was conducted on the tissue levels of AhR and serum levels of PSA in 53 PCa cases from 2008-2011 and associations between each and background and lifestyle related factors were determined. Results: Although the AhR was overexpressed in PCa and correlated with the age of patients, it did not correlate with PSA levels.Of nutritional factors, increased intake of polysaturated fats and fish in the routine regimen of PCa cases increased the PSA levels significantly. Conclusions: AhR overexpression in PCa pontws to roles of EDCs in PCa but without any direct association with PSA levels. However, PSA levels are affected by exposure to possible toxicants in foods whichneed to be assessed as possible risk factors of PCa in future studies.

      • Role of Vitamin D Deficiency and Lack of Sun Exposure in the Incidence of Premenopausal Breast Cancer: a Case Control Study in Sabzevar, Iran

        Bidgoli, Sepideh Arbabi,Azarshab, Hamid Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.8

        Background: Vitamin D has been suggested as one of the critical factors for female reproductive health with protective activities against different cancers but there are conflicting facts regarding its role on breast cancer without any clear data on premenopausal cases. This study aimed to evaluate the role of vitamin D from dietary sources and sunlight exposure on the incidence of premenopausal breast cancer. Materials and Methods: We conducted a case control study on 60 newly diagnosed premenopausal breast cancer patients and 116 normal women who lived in Sabzevar and surrounding villages in Razavi, Khorasan, a rural and conservative area of Iran. Results: The mean concentrations of 25-OH vitamin D in cases and controls were $15.2{\pm}8.15$ vs $15.5{\pm}7/45ng/ml$, both well below normal values elsewhere. In fact 50% of analyzed individuals showed very severe or severe vitamin D deficiency and the rest (25%) were detected in suboptimal levels. Although the lack of vitamin D and calcium supplementation increased slightly the risk of premenopausal breast cancer (p=0.009, OR=1.115, CI 95%=1.049-1.187), higher prevalence of weekly egg consumption (86.66% vs 96.55%, p=0.023, OR=0.232, CI 95% 0.065-0.806) showed a slight protective role. The last but the most important risk factor was lack of sunlight exposure because the breast cancer patients had total body coverage from sun (p=0.007, OR=10.131, CI 98% 0.314-78.102). Conclusion: This study pointed out the role of vitamin D and other possible risk factors on the development and growth of breast tumors in this special geographical region. Although this study has revealed the interactions between hormonal and environmental factors in this province of Iran, understanding the deficiency pattern and its contribution to other lifestyle factors elsewhere is also necessary.

      • Role of Endocrine Disrupting Chemicals in the Occurrence of Benign Uterine Leiomyomata: Special Emphasis on AhR Tissue Levels

        Bidgoli, Sepideh Arbabi,Khorasani, Hoda,Keihan, Heideh,Sadeghipour, Alireza,Mehdizadeh, Abolfazl Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.11

        Although benign uterine leiomyomata (LMA) is the most common reproductive tumor in premenopausal women, its etiology is largely unknown. We aimed in the present study to demonstrate the potential role of environmental factors with estrogenic activity in tumor etiology by focusing on the role of aryl hydrocarbon receptor (AhR) which mediates the effects of many environmental endocrine disruptors and contributes to the loss of normal ovarian function in polluted environments. This case-control study aimed to compare the interactions between AhR and lifestyle factors in a clinical setting for the first time among 138 newly diagnosed LMA patients and 138 normal controls who lived in Tehran and Mashhad, respectively, during the last 10 years. To conduct immunohistochemical studies using appropriate monoclonal antibodies, 30 cases were selected retrospectively from 2009-2011 from the pathology departments of two university hospitals in Tehran. Although the levels of sex steroid receptors were similar in adjacent myometrium and uterine leiomyomas of all cases, AhR was significantly overexpressed (p=0.034, OR=1.667) in uterine LMA and this overexpression was correlated with living in Tehran [(p=0.04, OR=16 (1.216-210.58)], smoking[P=0.04, OR=2.085 (1.29-3.371)], living near polycyclic aromative hydrocarbon producing companies [p=0.007, OR=2.22 (1.256-3.926)] and eating grilled meat [p=0.042, OR=1.28 (1.92-3.842)]. Our study contributes to the understanding of the effects of EDCs on AhR levels as well as women's health and points out possible risk factors for the development and growth of uterine LMA. It seems that the development of LMA could be the result of interactions between hormonal and environmental factors.

      • Mutagenicity Assessment of Drinking Water in Combination with Flavored Black Tea Bags: a Cross Sectional Study in Tehran

        Alebouyeh, Farzaneh,Bidgoli, Sepideh Arbabi,Ziarati, Parisa,Heshmati, Masoomeh,Qomi, Mahnaz Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.17

        Diseases related to water impurities may present as major public health burdens. The present study aimed to assess the mutagenicity of drinking water from different zones of Tehran, and evaluate possible health risks through making tea with tea bags, by Ames mutagenicity test using TA 100, TA 98 and YG1029 strains. For this purpose, 450 water samples were collected over the period of July to December 2014 from 5 different zones of Tehran. Except for one sample, no mutagenic potential was detected during these two seasons and the MI scores were almost normal (${\leq}1-1.6$) in TA 100, TA 98 and YG1029 strains. Although no mutagenic effects were considered in TA 98 and TA 100 in the test samples of our three evaluated tea bag brands, one sample from a local company showed mutagenic effects in the YG1029 strain (MI=1.7-1.9 and 2) after prolonged (10-15 min.) steeping. Despite the mild mutagenic effect discovered for one of the brand, this cross sectional study showed relative safety of water samples and black tea bags in Tehran. According to the sensitivity of YG1029 to the mutagenic potential of water and black tea, even without metabolic activation by s9 fraction, this metabolizer strain could be considered as sensitive and applicable to food samples for quantitative analysis of mutagens.

      • Roles of Kermanshahi Oil, Animal Fat, Dietary and Non-Dietary Vitamin D and other Nutrients in Increased Risk of Premenopausal Breast Cancer: A Case Control Study in Kermanshah, Iran

        Salarabadi, Asadollah,Bidgoli, Sepideh Arbabi,Madani, Sayed Hamid Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.17

        Background: Kermanshahi oil is one the most favorable oils in Iran especially in Kermanshah province. We aimed to evaluate the role of usual intake of Kermanshahi oil and other kinds of dietary fats as well as different meats, vegetables and fruits, carbohydrates, cereals, grains, sweets, candy and lifestyle habits in risk of breast cancer. Materials and Methods: A case-control study with 47 consecutive, newly diagnosed premenopausal breast-cancer patients and 105 age and socioeconomic matched healthy women was conducted from 2013-2014 in Imam Reza hospital of Kermanshah using a standardized, validated questionnaire assessing various anthropometric, socio-demographic, lifestyle and dietary characteristics. Results: Kermanshahi oil intake was associated with a 2.1-fold (OR=2.123, 95% CI 1.332-3.38) (p=0.002) higher likelihood of having breast cancer, while daily intake of other solid animal fats also increased the likelihood by 2.8-fold (OR = 2.754, 95% CI 1.43-5.273) (p < 0.001), after various adjustments made. Lack of fish oil, white meat, vegetables, soy products, nuts and dairy products (especially during adolescence) in daily regimens and lack of sun exposure were significantly associated with premenopausal breast cancer risk in this region. Conclusions: This study suggested that animal fat increases the risk of premenopausal breast cancer but many other dietary and non-dietary factors including calcium and vitamin D deficiency are consistently associated with increased odds of breast cancer in this region.

        Ovarian cysts disappear after 14-day oral regimen of Korean red ginseng extract in letrozole-induced polycystic ovarian syndrome

        Niknaz Moradi,Sepideh Arbabi Bidgoli,Shahla Chaichian 대한산부인과학회 2021 Obstetrics & Gynecology Science Vol.64 No.3

        ObjectiveHormonal and inflammatory mechanisms are involved in the pathogenesis of polycystic ovarian syndrome (PCOS),which is a prevalent metabolic disorder among women of reproductive age. We aimed to evaluate the comparativeefficiency of short-term oral administration of Korean red ginseng extract (KRGE) and the standard treatmenton PCOS by focusing on the histopathological parameters and serum levels of luteinizing hormone (LH), folliclestimulatinghormone (FSH), testosterone, and nuclear factor kappa B (NF-κB). MethodsA PCOS rat model was established by oral gavage of letrozole (1 mg/kg) for 21 days. The serum levels of LH, FSH,testosterone, and NF-κB were measured, and the morphological features and differences of the ovaries wereexamined in each group using a light microscope before and after 14 days of treatment with oral regimens—KRGE,oral contraceptives (OCPs), KRGE+OCPs, and carboxymethyl cellulose (CMC). ResultsOCPs alone could not normalize the mean ovarian weights of PCOS rats despite the 14-day oral regimen, but theywere more effective in reducing the number and size of cysts compared to others. KRGE alone and in combinationwith OCPs was effective in normalizing abnormal ovarian weights, decreasing LH serum levels, and dissipating theovarian cysts in PCOS rats. However, when combined with the standard regimen, KRGE showed additional therapeuticeffects by efficiently reducing serum testosterone and NF-κB levels. ConclusionOur necropsy and histopathological evidence suggests the efficacy of KRGE as a novel integrative medicine againstabnormal multiple follicular cysts. However, antiandrogenic and anti-inflammatory effects were only seen in animalsthat were administered a combination of KRGE and the standard regimen.

      • Increased Risk of Childhood Acute Lymphoblastic Leukemia (ALL) by Prenatal and Postnatal Exposure to High Voltage Power Lines : A Case Control Study in Isfahan, Iran

        Tabrizi, Maral Mazloomi,Bidgoli, Sepideh Arbabi Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.6

        Childhood acute lymphoblastic leukemia (ALL) is one of the most common hematologic malignancies, accounting for one fourth of all childhood cancer cases. Exposure to environmental factors around the time of conception or pregnancy can increase the risk of ALL in the offspring.This study aimed to evaluted the role of prenatal and postnatal exposure to high voltage power lines on the incidence of childhood ALL.This cross-sectional case control study was carried out on 22 cases and 100 controls who were born and lived in low socioeconomic families in Isfahan and hospitalized for therapeutic purposes in different hospitals from 2013-2014.With regard to the underlying risk factors, familial history and parental factors were noted but in this age, socioeonomic and zonal matched case control study, prenatal and childhood exposure to high voltage power lines was considered as the most important environmental risk factors of ALL (p=0.006, OR=3.651, CI 95%, 1.692-7.878). As the population was of low socioeconomic background, use of mobiles, computers and microwave was negligible. Moreover prenatal and postnatal exposure to indoor electrically charged objects was not determined to be a significant environmental factor. Thus, pre and post natal exposure to high voltage power lines and living in pollutant regions as well as familial influence could be described as risk factors of ALL for the first time in a low socioeconomic status Iranian population.
