[ 1 ] - بررسی ارتباط بین شاخص توده بدنی (BMI) و پلی‌مورفیسم C11377G ژن آدیپونکتین با سرطان پستان

زمینه و هدف: هورمون آدیپونکتین از هورمون‌های چاقی و از عوامل دخیل در ایجاد سرطان پستان در نظر گرفته شده که با تغییرات ژنی این تأثیر افزایش می‌یابد. هدف از این مطالعه بررسی ارتباط بین شاخص توده بدنی و پلی‌مورفیسم C11377G از ژن آدیپونکتین با خطر ابتلا به سرطان پستان است. مواد و روش‌ها: برای انجام تحقیق، از 128 فرد مبتلا به سرطان پستان و 128 فرد سالم خون‌گیری شد و پس از استخراج DNA به روش نمک اشبا...

[ 2 ] - Association between the Asp327Asn Polymorphism of Sex Hormone-Binding Globulin Gene and Prostate Cancer

Background: By binding SHBG hormone to sex hormones, in addition to carrying them in the blood, they regulate the amount of tissue availability. Since the genetic changes in the structure of globulin affect it’s binding to hormones, so in this study the effects of single nucleotide change in exon 8 or rs 6259 in the incidence of prostate cancer is evaluated. Methods: The study populati...

[ 3 ] - The relationship between Human Papillomavirus and Epstein-Barr virus infections with breast cancer of Iranian patients

Background: Breast cancer is the malignancy in humans and other mammals. Several risk factors are involved in their appearance such as higher hormone levels and obesity. Identification of a mouse mammary tumor virus supports a viral etiology for breast tumors in animals. Viruses have been implicated in the development of various cancers, but viral induction for formation breast cancer is contro...

[ 4 ] - Relationships between Body Mass Index, Serum Leptin Levels, and 17β-Estradiol in Postmenopausal Women with Breast Cancer: A Case-Control Study

Introduction: There is a close relationship between the incidence of breast cancer and fat intake in different populations. Overweight and obesity during menopause can increase the risk of breast cancer in women. Hormones like estrogen and leptin are factors that affect the growth and proliferation of breast cells. The main purpose of this study was to evaluate the relationships between body ma...

[ 5 ] - Serum Liver proteins and 17β-estradiol in Postmenopausal Women with Breast Cancer

Background: Breast cancer is a hormone-dependent malignancy that is associated with estrogen and progesterone interactions. The liver is the most important organ to be affected by the metastasis of breast cancer, which causes functional impairment. We compared levels of obesity, 17β-estradiol, and secreted proteins in postmenopausal women with breast cancer but without hepatic symptoms to those...

[ 6 ] - Detection of single Nucleotide Polymorphism E326K of SHBG Gene in Breast Cancer of Iranian Females

Background & Objective: Sex Hormone-Binding Globulin (SHBG) is a plasma glycoprotein that regulates the action of steroid hormones on several levels. Since SHBG is one of the growth regulators of breast cancer cells, the aim of this study was to evaluate the association between polymorphisms E326K and the risk of breast cancer. Materials & Methods: This study was done as a case-control study on...

[ 7 ] - The impact of BMI, Smoking, Family History and Ala 119 Ser (rs1056827) Polymorphism of CYP1B1*2 Genes with Susceptibility to Prostate Cancer among Iranian Men

Background and Aims: The genes involved in detoxification and the elimination of toxic metabolites have a vital role in cancer pathogenesis. Also, there is evidence that higher amounts of body fat are associated with increased risks of several cancers. The current study aims to identify the relationship of age, body mass index (BMI), smoking, family history, and polymorphism rs1056827 of CYP1B1...

[ 8 ] - Determination of hemolysine genes frequency in antibiotic-resistant Staphylococcus aureus isolated from wound and urine samples of patients

Background: Staphylococcus aureus is a pathogenic bacterium that can target host cell membranes with virulence factors such as toxins and peptides. This study was evaluated the frequency of alpha, beta, and delta hemolysine genes in antibiotic-resistant Staphylococcus aureus isolated from patients' urine and wound samples. Materials and methods: This cross-sectional study was performed on 100 a...
