In vivo imaging of brain estrogen receptors in rats: a 16α-18F-fluoro-17β-estradiol PET study.
UNLABELLED The steroid hormone estrogen is important for brain functioning and is thought to be involved in brain diseases, such as Alzheimer disease and depression. The action of estrogen is mediated by estrogen receptors (ERs). To understand the role of estrogens in brain functioning, it is important to study ERs in the brain. The aims of the present study were to determine whether ERs could ...
متن کاملPrognostic Values of Estrogen and Progesterone Expression Receptors in Ovarian Papillary Serous Carcinoma
Background and Objectives: Presence of steroid hormone receptors (estrogen and progesterone) in the tumor tissues of various organs correlates with response to therapy and prognosis. Since their role in ovarian cancer is still controversial, in this study we investigated the expression and prognostic value of the estrogen receptor (ER) and progesterone receptors (PR) in ovarian papillary ser...
متن کاملSex steroid hormones and brain function: PET imaging as a tool for research
Sex steroid hormones are major regulators of sexual characteristic among species. These hormones, however, are also produced in the brain. Steroidal hormone-mediated signalling via the corresponding hormone receptors can influence brain function at the cellular level and thus affect behaviour and higher brain functions. Altered steroid hormone signalling has been associated with psychiatric dis...
متن کاملRole of melatonin receptors in the effect of estrogen on brain edema, intracranial pressure and expression of aquaporin 4 after traumatic brain injury
Objective(s): Traumatic brain injury (TBI) is one of the most common causes of death and disability in modern societies. The role of steroids and melatonin is recognized as a neuroprotective factor in traumatic injuries. This study examined the role of melatonin receptors in the neuroprotective effects of estrogen. Materials and Methods: Seventy female ovariectomized Wistar rats were divided in...
متن کاملIntermediary role of kisspeptin in the stimulation of gonadotropin-releasing hormone neurons by estrogen in the preoptic area of sheep brain
Introduction: The role of estrogen in the stimulation of gonadotropin-releasing hormone (GnRH) neurons is clear. These neurons do not express estrogen alpha receptors, so other mediator neurons should be present to transmit the positive feedback effect of estrogen to the GnRH neurons. Kisspeptin neurons have an important role in the stimulation of GnRH neurons, so they can be the mediator of...
