The secretion of prolactin (PRL) from the anterior lobe (AL) of the pituitary gland is tonically inhibited by dopamine (DA) of hypothalamic origin. While ovarian steroids play a role in the regulation of the secretion of PRL, their effect on all three populations of hypothalamic neuroendocrine dopaminergic neurons is not fully understood. In this study we describe the effects of ovarian steroid...

Indirect evidence suggests that estrogen is involved in the etiology of breast cancer. Estrogen is also thought to modulate nitric oxide (NO) in human breast tumor tissue via regulation of inducible nitric oxide synthase (iNOS). Objectives of this study were to determine whether estradiol (E2) affects iNOS expression level in breast cancer cells and to study the effect of various concentrations...

Background & Aim: Electromagnetic waves can damage sex organs and cause hormonal disorders, whereas garlic is known as reducing risk factors for various diseases. The aim of this study was to investigate the probable effects of mobile phone radiation and consumption of garlic on estrogen and progesterone levels and ovarian changes. Experimental: Five groups of rats (n = 8) were used which grou...

Insulin and insulin-like growth factors (IGFs) stimulate the growth of human breast cancer cells in vitro. The type I somatomedin receptor (SR), expressed in these cells, may mediate the mitogenic effects of these peptides. We have examined the effect of type I SR blockade on human breast cancer growth with a monoclonal antibody (alpha-IR3) that blocks the receptor binding domain. alpha-IR3 inh...

OBJECTIVES To investigate the difference of serum estrogen, serum lipids and inflammatory factors levels in postmenopausal women with coronary heart blood stasis syndrome and non-blood stasis syndrome. METHODS Twenty five healthy postmenopausal women were selected as a healthy control group who were compared with 43 postmenopausal women with coronary heart disease (CHD) first visiting a docto...

Persistent unopposed estrogen stimulation is a central oncogenic mechanism driving the formation of type I endometrial cancer. Recent epidemiologic and clinical studies of endometrial cancer have also revealed a role for insulin resistance, clinically manifested by chronic inflammation. However, the role of inflammation in estrogen-driven endometrial cancer is not well characterized. In this st...
