Endometriosis and leiomyoma are both common estrogen-related gynaecological diseases. We aimed to elucidate the association of estrogen receptor alpha (ERalpha)-351 A>G (XbaI) and -397 T>C (PvuII) gene polymorphisms with endometriosis and l…

OBJECTIVE: To investigate the association of endometriosis with estrogen receptor alpha (ER alpha) and cytochrome P450c17alpha (CYP17) gene polymorphisms in light of the fact that estrogen plays a role in the pathogenesis of endometriosis a…

Interleukin (IL)-2 R-627*C homozygote and C allele are related to higher susceptibility to endometriosis. Interleukin-12Rbeta1 codon 378 and IL-18 105 gene polymorphisms are not correlated with endometriosis development.

Transforming growth factor beta (TGF-B) family members are multi-functional cytokines that play a key role in cellular growth, proliferation, and differentiation. The aim of the study was to investigate whether the TGF-B1-509 gene polymorph…

Epidermal growth factor receptor (EGFR) is a regulator of angiogenesis and mediator of sex steroid-induced cell growth and differentiation. We observed that EGFR gene 2073*T-related genotypes and allele are associated with higher susceptibi…

OBJECTIVE: Androgen receptor (AR) was detected in leiomyoma. AR gene has a polymorphic microsatellite encoding cytosine, adenine, and guanine (CAG) repeats. We aimed to investigate the association between the AR gene CAG repeats and leiomyo…

Endometriosis displays features similar to malignancy, ranging from neovascularization to local invasion and aggressive spread to distant organs. The altered vascular-related genes might be related to the development of endometriosis. This …

Estrogen plays a role in the pathogenesis of endometriosis. The CYP17 gene codes for the cytochrome P450c17alpha enzyme that is involved in the estrogen biosynthesis. We aimed to investigate if CYP17 polymorphism could be used as marker to …

Glutathione S-transferase M1 (GSTM1), one member of the GST family, is responsible for metabolism of xenobiotics and carcinogens. Myeloperoxidase (MPO) plays an important role in the oxidation and activation of carcinogens and nitric oxide.…

OBJECTIVE: To investigate whether vascular endothelial growth factor (VEGF) gene 5'-UTR-460 polymorphism could be used as a marker of susceptibility to endometriosis. STUDY DESIGN: Women were divided into 2 groups, endometriosis (n = 122) …

OBJECTIVE: To investigate whether interleukin-10 (IL-10) -627 gene promoter polymorphism could be used as a marker of susceptibility to endometriosis. STUDY DESIGN: Women were divided into 2 groups, endometriosis (n = 130) and nonendometri…

Interleukin-4 (IL-4) is a cytokine with anti-inflammatory properties. Tumor necrosis factor alpha (TNF-alpha), a pluripotent proinflammatory cytokine, plays an important role in the process of numerous inflammatory and autoimmune diseases. …

OBJECTIVE: To evaluate the association between endometriosis and the p53 polymorphism. DESIGN: Prospective study. SETTING: Department of gynecology and genetics in a medical center. PATIENT(S): Women with and without endometriosis. INTE…

PURPOSE: To evaluate the antral follicle (AF) counting in predicting the outcome after controlled ovarian hyperstimulation (COH) and IVF-ET. METHODS: Infertile women who accepted the COH and IVF-ET were included prospectively. Day

p21, an important regulator of the cell cycle, acts as a mediator of the growth-suppressing and -promoting functions of p53. We aimed to investigate the association between codon 31 polymorphisms of p21 gene and endometriosis. Women were di…

PURPOSE: We aimed to investigate if interleukin-1 beta (IL-1 beta) and IL-1 receptor antagonist (IL-1Ra) gene polymorphism could be used as markers of susceptibility in endometriosis. MATERIALS AND METHODS: Women were divided into two grou…

OBJECTIVE: Recurrent endometriomas after medical or surgical treatment is a difficult clinical problem for those patients who wish to perform ovulation induction. Therefore we tried to investigate the efficacy of sclerotherapy as an adjuvan…
