CONTEXT Products of at least five specific steroidogenic genes, including steroidogenic acute regulatory protein (StAR), which facilitates the entry of cytosolic cholesterol into the mitochondrion, side chain cleavage P450 enzyme, 3beta-hydroxysteroid-dehydrogenase-2, 17-hydroxylase/17-20-lyase, and aromatase, which catalyzes the final step, are necessary(More)
Several improvements in ovarian cancer treatment have been achieved in recent years, both in surgery and in combination chemotherapy with targeting. However, ovarian tumors remain the women's cancers with highest mortality rates. In this scenario, a pivotal role has been endorsed to the immunological environment and to the immunological mechanisms involved(More)
The objective of this study was to determine whether there was a threshold for the number of CGG repeats in the FMR1 (fragile X) gene in premature ovarian ageing and premature ovarian failure and to investigate the association of this sequence with serum concentrations of anti-Müllerian hormone (AMH), inhibin B, anti-thyroid and anti-adrenal autoantibodies.(More)
Chemokines and their receptors play diverse roles in malignant tumor progression, particularly as key mediators of tumor stroma interactions. C-C motif chemokine ligand 2 (CCL2) also called monocyte chemoattractant protein-1 (MCP-1), belongs to the C-C motif chemokine sub-family and is currently believed to mediate its actions through one receptor, C-C(More)
OBJECTIVE To determine the effects of letrozole and melatonin on surgically induced endometriosis in a rat endometriosis model. DESIGN Prospective, randomized, controlled, experimental study. SETTING Experimental Research Center of Yeditepe University (YUDETAM). ANIMAL(S) Thirty female, nonpregnant, nulligravid Wistar-Hannover albino rats. (More)
AIMS To determine the effects of different doses of melatonin treatment on endometrial implants, the activity of antioxidant enzyme superoxide dismutase (SOD), the angiogenesis factor, the vascular endothelial growth factor (VEGF) and the waste metabolite product of lipid peroxidation malondialdehyde (MDA) in an oophorectomized rat endometriosis model. (More)
OBJECTIVE To determine the effects of etanercept (anti-TNF-α) on surgically induced endometriosis in a rat model. MATERIALS AND METHODS This is a prospective, randomized, controlled, experimental study that was carried out at the Experimental Research Center of Yeditepe University (YUDETAM). Thirty female nonpregnant, nulligravid Wistar-Hannover albino(More)
Endometriosis is regarded as a complex trait, in which genetic and environmental factors contribute to the disease phenotype. We investigated whether the interleukin (IL) 1beta (+3953) polymorphism is associated with the severity of endometriosis. Diagnosis of endometriosis was made on the basis of laparoscopic findings. Stage of endometriosis was(More)
In this study, we aimed to investigate a possible association of the COX-2 polymorphisms (-765G→C and -1195A→G) and with the risk of developing epithelial ovarian carcinoma (EOC). COX-2 gene polymorphisms was investigated in 111 healthy women and 57 patients with EOC. Individuals who had -765 CG, -1195 AA genotype, and -765 C allele had increased risk for(More)
