ارتباط بین پلیمورفیسم ((Ile105Val ژن گلوتاتیون S- ترانسفراز P1 (GSTP1) و خطر ابتلا به لیومیوم رحمی در جمعیت ایرانی
Authors
Abstract:
Background: Uterine leiomyoma is one of the most common benign smooth muscle tumors occurring in 20-40% of women worldwide in their reproductive years. Recent studies revealed that estrogen plays an important role in the pathogenesis of this disease. Since glutathione S-transferase (GST) gene family are involved in the biosynthesis of estrogen, the prior probability that variants at this locus are associated with uterine leiomyoma is likely to be above the null. Therefore, this study was carried out to examine whether GSTP1 polymorphism (Ile105Val) is associated with increased risk of uterine leiomyoma in Iranian population. Methods: In this case-control study, 50 women diagnosed with uterine leiomyoma and 50 healthy controls were recruited from subjects referred to the Pasteur Institute of Iran from November 2012 to September 2013. The genomic DNA was extracted from peripheral blood leucocytes using the standard phenol-chloroform method and subsequently the GSTP1 polymorphism was genotyped using amplification refractory mutation system-polymerase chain reaction (ARMS-PCR). Logistic regression analysis was applied to estimate odds ratios and 95% confidence intervals after age adjustment using the SPSS statistical software package, version 18.0. Results: The results showed significant differences between case and control groups in terms of genotype frequency (P<0.0001). In addition, the results indicated that the presence of the valine allele significantly increased risk of uterine leiomyoma about three times more in individuals carrying the mutant allele compared to control group (Odds Ratio: 3.34 95%CI: 1.82-6.15 P<0.0001). Conclusion: To our knowledge, this is the first study performed in Iranian population assessing the association between GSTP1 Ile105Val polymorphism and risk of uterine leiomyoma. However, further extensive studies with a large number of samples from different populations and ethnicities are required to validate the results obtained in this study.

Background: Uterine myomas are benign tumors of the uterus and the most common solid pelvic tumors causing symptoms in approximately 25% of women in their reproductive years. However, its etiology and pathogenesis remain obscure there is increasing evidence that endometriosis is inherited as a complex genetic trait. Recent studies indicated the involvement of glutathione S-transferase M1 (GSTM1...

Introdution: Endometriosis is one of the most common gynecologic disorders and shows significantly elevated prevalence in industrial regions. Additionally, a possible genetic predisposition is assumed for the disease. Glutathione S-transferases (GSTs) are enzymes participated in the metabolism of many human disease-causing mutagens, carcinogens and environmental pollutants. A functionally signi...

Abstract: Background: Autoimmune hepatitis (AIH) is a chronic inflammatory liver disorder of unknown etiology. The search for gene polymorphisms has suggested that Glutathion-s-transferase (GST), enzymes that metabolize carcinogens, drug, and foreign compounds, may play a role in susceptibility to autoimmune liver disease and its severity. The objective of this study was to investigate for a r...

Background: Pi-GST and Mu-GST are subclasses of glutathione S-transferase that present on human sperm surface and play an important role against oxidative stress. Therefore, any defects in the enzyme activity may be associated with male infertility.In this study the polymorphisms of GSTM1 and GSTP1 in association with enzyme activity and sperm parameters were studied. Methods: This case-contro...
