Association of estrogen receptor alpha (ERα) gene polymorphisms with endometrial thickness and lipid profile in women with breast cancer treated with aromatase inhibitors.

Aromatase inhibitors (AIs) provide an alternative to tamoxifen as an adjuvant therapy for post-menopausal, hormone-receptor positive breast cancer patients. The aim of the present study was to evaluate the effect of PvuII and XbaI polymorphisms of the ERα gene at ΑΙs treatment's adverse effects in post-menopausal women with breast cancer. The study included 87 post-menopausal women with ER-positive breast cancer treated with AIs and 80 healthy controls.

No association of the G972S polymorphism of the insulin receptor substrate-1 gene with polycystic ovary syndrome in lean PCOS women with biochemical hyperandrogenemia.

Purpose: The aim of the present study was to determine the prevalence and association of the G972S polymorphism of the insulin receptor substrate-1 gene (IRS-1 G972S SNP) with polycystic ovary syndrome (PCOS) and insulin resistance-related traits in a distinct phenotypic group of lean PCOS women with biochemical hyperandrogenemia, excluding obesity, which is considered to be an aggravating parameter of insulin resistance.

Methods: The study included 162 women with PCOS and 122 regularly menstruating, ovulatory women as controls. Physical measurements included weight, height, fat-free mass, fat mass, systolic and diastolic blood pressure and resting heart rate.

Association of the Pro12Ala polymorphism in peroxisome proliferator-activated receptor gamma2 with decreased basic metabolic rate in women with polycystic ovary syndrome.

Objective: The peroxisome proliferator-activated receptor (PPAR)gamma is a transcription factor involved in glucose homeostasis and energy metabolism. A missense mutation at codon 12 in the PPARgamma2 has been associated with increased body mass index (BMI) and attenuated insulin resistance (IR) in polycystic ovary syndrome (PCOS). We have recently shown a decreased basic metabolic rate (BMR) in PCOS.

Association of the 17-hydroxysteroid dehydrogenase type 5 gene polymorphism (-71A/G HSD17B5 SNP) with hyperandrogenemia in polycystic ovary syndrome (PCOS).

Objective: To evaluate the association of an activating single-nucleotide polymorphism (SNP) at position -71 of the promoter of 17beta-hydroxysteroid dehydrogenase type 5 gene (-71A/G HSD17B5 SNP) and polycystic ovary syndrome (PCOS) in a well characterized cohort of caucasian PCOS women with biochemical hyperandrogenemia.

Design: The PCOS patients and unrelated healthy control subjects were genotyped for the -71A/G HSD17B5 SNP. The acquired genotypic data was tested for association with PCOS and other quantitative phenotypic traits of the syndrome in PCOS patients.

The vitronectin gene in rainbow trout: cloning, expression and phylogenetic analysis.

Vitronectin is a major cell adhesion glycoprotein that is found in plasma and the extracellular matrix. Vitronectin consists of an N-terminal somatomedin B domain and two hemopexin-like domains and controls functions including cell adhesion, migration, haemostasis and immune defence. In order to study the molecular evolution of the complement lytic pathway regulation, we have cloned and characterized the vitronectin gene from rainbow trout (Oncorhynchus mykiss).
