OBJECTIVE Cholesterol gallstone disease (CGD) is a multifactorial and multistep disease. Apart from female gender and increasing age being the documented non-modifiable risk factor for gallstones the pathobiological mechanisms underlying the phenotypic expression of CGD appear to be rather complex, and one or more variations in genes could play critical roles in the diverse pathways further pro...

BACKGROUND Osteoarthritis (OA) is a common chronic disease of the joints. Genetic factors may play a role in its development, and polymorphisms in the estrogen receptor alpha gene (ERα) have been associated with OA. However, previous studies into this relationship have reported inconsistent results, so we aimed to systematically review the association between ERα polymorphisms and OA susceptibi...

Systemic lupus erythematosus (SLE) is an autoimmune disease that affects a number of different organs and tissues. Interleukin-1 (IL1) and estrogen are considered potential elements in the pathology of SLE. Recently, the variable number of tandem repeats (VNTR) polymorphism in the IL1 receptor antagonist gene (IL1-RN) and PvuII (rs2234693) and XbaI (rs9340799) polymorphisms in the estrogen rece...

BACKGROUND Estrogen is thought to play a key role in anxiety, but it remains unknown whether genetic variants in the estrogen receptors (ERs) can influence the risk of anxiety. This study investigated whether ESR1 and ESR2 gene variants were associated with specific anxiety disorders in postmenopausal women and evaluated the potential modifying effect of hormone treatment (HT) on these associat...

BACKGROUND Important candidate genes involved in the ovarian response to exogenous FSH are the estrogen receptor genes (ESRs), since the effects of estrogens on follicle growth, maturation and oocyte release. It is known that some markers of ovarian stimulation can help to personalize the treatment, adjusting the dose of exogenous rFSH, thus preventing excessive wear of the patient. Inspired on...

OBJECTIVE A pilot study to examine accrual rates, efficiency of data capture approaches, study design and genotyping capacity for a future genetic validation study was undertaken. DESIGN The process pilot evaluated feasibility of applying a matched case-control design to validate association of two candidate estrogen receptor (ER) single nucleotide polymorphisms (SNPs) with incidence of venot...

Single nucleotide polymorphism (SNP) genotype frequencies were examined to determine whether variation in 6 estrogen-related genes was associated with differences in cognitive functioning in women at midlife. DNA from a multiracial/multiethnic sample of 875 African American, Caucasian, Chinese, and Japanese women aged 45 to 56 years participating in the Study of Women's Health Across the Nation...

Accumulating evidence suggests the involvement of estrogen in depression. Estrogen can modulate neurotransmitter turnover, enhancing the levels of serotonin and noradrenaline (norepinephrine), and it is involved in the regulation of serotonin receptor number and function. Across the female reproductive life, fluctuating estrogen levels and low levels have been associated with depressed mood and...

Oestrogen is known to affect multiple aspects of human health, including complex traits such as cardiovascular disease, cancer, fracture risk, arthritis, behaviour and Alzheimer’s disease. Oestrogen receptor a (ESR1), one of two known oestrogen activated transcription factors, is expressed throughout many tissues. It can regulate gene expression by both oestrogen-dependent and oestrogenindepend...
