Dear Editor-in-ChiefMalignant melanoma is a tumor arising from melanocyte; this tumor rarely occurs before puberty, with higher mortality rate in males and better survival rate in female patients affected by metastatic melanoma (1, 2). These facts propose that a relationship and association may exist between estrogens and melanoma. The effects of estrogens are mediated by...

1. ABSTRACT This review summaries recent evidence from clinical and basic science studies on estrogen central nervous system. For decades, estrogen was thought of only as a "sex hormone" and plays a fundamental role in regulating behavioral and physiological events. In recent years, accumulated evidence shows that estrogen also plays very important roles in the brain. Recent basic science studi...

Estrogen acts in the hypothalamic ventromedial nucleus (VMH) to promote female sexual behavior. One potential mechanism through which estrogen may facilitate this behavior is by reconfiguring synaptic connections within the VMH. Estrogen treatment increases the number of synapses and dendritic spines in the VMH, but how this remodeling occurs within the context of the local, behaviorally releva...

conclusions it is concluded that dietary supplementation of l-carnitine has no effect on serum levels of estrogen, progesterone and testosterone in cats following ovariohysterectomy. long-term study is recommended. background the benefits of the addition of l-carnitine to the diet of cats to control weight gain after the removal of their ovaries have been highlighted recently. it is also used i...

Estrogen disrupting pesticides (EDP) are that modify estrogen activities in estrogen-producing vertebrates. A substantial amount of these has been detected human tissues, and they function directly to disrupt synthesis or effector cells. This study examines EDP’s ecological distribution across Nebraska counties its association with estrogen-related cancers (ERC). To determine the selected EDP, ...

Estrogen receptor (ER) signaling is a critical regulator of cell proliferation, differentiation, and survival in breast cancer (BC) other hormone-sensitive cancers. In this review, we explore the mechanism ER-dependent downstream BC role estrogens as growth factors necessary for invasion dissemination. The significance clinical implications ER BC, including potential endocrine therapies that ta...

Estrogen has multiple actions in the brain to modulate homeostasis, synaptic plasticity/cognition and neuroprotection. While many of these actions undoubtedly involve mediation via the classical genomic mechanism of regulation of transcription of genes via estrogen nuclear receptors, there has been growing interest in the rapid nongenomic effects of estrogen and the role they may play in the ne...

BACKGROUND Estrogen pretreatment has been shown to attenuate the development of heart hypertrophy, but it is not known whether estrogen could also rescue heart failure (HF). Furthermore, the heart has all the machinery to locally biosynthesize estrogen via aromatase, but the role of local cardiac estrogen synthesis in HF has not yet been studied. Here we hypothesized that cardiac estrogen is re...

Estrogen surge following progesterone withdrawal at parturition plays an important role in initiating maternal behavior in various rodent species. Systemic estrogen treatment shortens the latency to onset of maternal behavior in nulliparous female rats that have not experienced parturition. In contrast, nulliparous laboratory mice show rapid onset of maternal behavior without estrogen treatment...
