Gestation and delivery can increase intra-abdominal pressure, which are well-known risk factors for Pelvic Organ Prolapse (POP). But the pathogenesis mechanism of POP remains unclear. Our previous research showed that the expression of glutathione peroxidase type 1 (GPX1) decreased in pelvic floor ligaments from POP patients, implying that oxidative stress (OS) may be related to POP. The aim of...
BACKGROUND/AIMS Increasing evidence shows that oxidative stress plays an important part in the pathophysiological mechanisms of preeclampsia (PE). Polymorphic variants of oxidative stress-related candidate genes GST1 and GPX1 can affect the antioxidant activities of their encoded enzymes. Therefore, this study aimed to explore the associational analysis between GSTP1 and GPX1 single nucleotide ...
Naked mole rat (MR) Heterocephalus glaber is a rodent model of delayed aging because of its unusually long life span (>28 years). It is also not known to develop cancer. In the current work, tissue imaging by x-ray fluorescence microscopy and direct analyses of trace elements revealed low levels of selenium in the MR liver and kidney, whereas MR and mouse brains had similar selenium levels. Thi...
زمینه و هدف: آرتریت روماتوئید، یک اختلال التهابی مزمن است که اساسا روی مفاصل محیطی و بافت های اطراف آن اثر می گذارد. فاکتورهای ژنتیکی و محیطی در پاتوژنز این بیماری موثر می باشند. در سال های اخیر، نقش استرس اکسیداتیو و آنزیم های دخیل در این فرآیند، در آرتریت روماتوئید مورد توجه قرار گرفته است. در مقابله با گونه های واکنش پذیر اکسیژن، آنزیم های آنتی اکسیدانی درونی و گلوتاتیون پراکسیدازها نقش برجس...
Much evidence supports the role of increased levels of reactive oxygen species (ROS) in the pathogenesis of cardiovascular diseases, including hypertension. The increased activity and expression of the reduced nicotinamideadenine dinucleotide phosphate oxidase observed in hypertensive populations have implicated the superoxide anion as one of the main species responsible. This view has been sup...
BACKGROUND The aim of this study was to establish whether the gene expression of estrogen receptor alpha (encoded by ESR1) correlates with the expression of glutathione peroxidase 1 (encoded by GPX1) in the tumor and adjacent tumor-free breast tissue, and whether this correlation is affected by breast cancer. Such relationships may give further insights into breast cancer pathology with respect...
Abstract Reactive oxygen species (ROS) have long been known to contribute the development and severity of Inflammatory Bowel Disease. However, more recent data indicates ROS may not always be pathogenic, in fact necessary for intestinal homeostasis. Thus, role intestine, antioxidant proteins which regulate ROS, contextual dose-dependent. Members glutathione peroxidase (GPx) family are antioxida...
Familial Mediterranean Fever (FMF) is a fairly common inflammatory disease in communities with mediterranean origin. It is characterized with autosomal recessive, recurrent short-term episodes of fever, peritoneal, pleural, synovial membrane involvement and skin lesions. The aim of the present study was to investigate possible associations between FMF and Ala-9Val polymorphism of MnSOD and Pro1...
