CHARACTERIZATION OF TRANSMEMBRANE PROTEIN 35 EXPRESSION: CONSIDERATIONS OF SEX AND OVARIAN HORMONES
… in expression. Moreover, we hypothesized that ovarian hormones were responsible for the observed sex differences in females. To determine this, we ovariectomized adult female Syrian hamsters to remove the major endogenous source of gonadal steroid hormones, and primed them with estradiol and …

Opioid induction of Fos in the female rat brain : modulation by ovarian hormones
… reproduction. It has also been established that ovarian hormones exert control over opioid peptide synthesis and opioid receptor gene expression. The present thesis investigated functional pathways by which opioids affect the sexual behaviour of female rats, by examining the induction of Fos …

Influence of cyclic changes in ovarian hormones on resting metabolic rate and appetite in women
… and this seems to respond to changes in the ovarian hormones, estradiol (E2) and progesterone (P4) within a menstrual cycle (MC). In light of the current prevalence of overweight and obese in the female population, it seems imperative to have a better understanding of the influence of the …

The Imipramine Binding Site: Effects of Aging, Ovarian Hormones, Adrenal Hormones, and Chronic Antidepressant Treatment
Binding sites for the antidepressant imipramine have been described in the brain and blood platelets of several species of animals, including rats and humans. Decreased levels of imipramine binding sites are found in depressed patients when compared to controls.

Physical activity and muscle function in females: Impact of ovarian hormones, bazedoxifene, and estrogen receptor alpha
… Although there is not a clear link between ovarian hormones and physical activity in women, there is a clear link in rodent models. I then identified that a combined treatment of estradiol+progesterone after ovariectomy increased physical activity in the form of wheel running distance and …

Ovarian hormones, but not androgens, mediate running-induced changes in high fat diet choice patterns in rats
… both organizational and activational effects of ovarian hormones play a role in female specific running-induced changes in diet choice patterns. Importantly, the activational effects of androgens are not required for the expression of HF diet avoidance in males.

Ovarian Hormone Modulation of Learning Strategy Preferences: A Role for Hippocampal Disinhibition
High levels of circulating ovarian hormones are related to use of the hippocampus-sensitive place learning strategy whereas low hormone levels are related to use of the striatum-sensitive response strategy. Other studies demonstrate that estrogen suppresses hippocampal GABAergic function and that …

Investigation of the role of smooth muscle function in egg transport in the mouse oviduct.
… and the effects of pharmacological agents, ovarian hormones, ovariectomy, and ligation and cauterization of the uterus from the oviduct on egg transport and oviduct calcium levels. The results indicate that the concentration of calcium could play an important role in the regulation of …

The impact of acute heat exposure on the heat shock response (HSR) between males and females
… immune cells of young adults, the influence of ovarian hormones on the molecular response remains unclear, despite their documented role in thermoregulation. This study investigated the molecular response to acute heat stress in males (n=11), eumenorrheic (EUM) females in the mid-luteal phase …

Regulation of Luteinizing Hormone and Catecholamine Release
… tested the interrelated hypotheses that the ovarian hormones produce their positive feedback effects on luteinizing hormone (LH) secretion through activation of noradrenergic and adrenergic systems in specific hypothalamic regions. Furthermore, the ovarian hormones may alter the activity of …

Effects of long-term hormone treatment on cognitive behavior and the structure of the medial prefrontal cortex during aging in female rats
… emphasize the need to evaluate the role of hormones in protecting against agerelated cognitive decline in an animal model. Furthermore, research has found that ovarian hormones alter brain structure and function. However, many studies evaluating the effects of estrogen and progesterone on …

Ultrasonic Communication and the Hormonal Modulation of Aggressive Behavior in the Female Hamster
… females have failed to reveal any individual ovarian or pituitary hormone that is required for the display of high levels of aggression. In contrast, it seems clear that a very specific combination of ovarian hormones normally accounts for the inhibition of fighting and stimulation of sexual …

NADPH-d staining in the supraoptic and paraventricular nuclei increases in late pregnant and lactating rats and is influenced by ovarian steroids and central oxytocin levels
… females. In other studies, the influence of ovarian hormones and central oxytocin infusion on NADPH-d staining in these nuclei was examined. Staining in the SON and PVN was compared among ovariectomized (ovex) animals exposed to either a steroid hormone regimen that mimics late pregnancy …

The Role of Exogenous Somatotropin, Ovariectomy and Extracellular Matrix in Bovine Mammary Gland Development
… designed to further characterize the role of ovarian hormones, growth hormone (GH)/IGF axis proteins and extracellular matrix (ECM) in the growth and development of prepubertal mammary glands. Prepubertal heifers were injected with either exogenous GH or subjected to ovariectomy (OVX). Mammary …

Role of Endogenous Dopamine in Regulation of Anterior Pituitary Hormone Secretion During Early Postpartum and Various Stages of the Estrous Cycle in Holstein Cows
… suppresses PRL secretion in cattle regardless of ovarian status. It is concluded that: 1) endogenous dopamine plays a stimulatory role in LH secretion during the anovulatory postpartum period and during the estrous cycle only when serum progesterone is low. 2) FLU decreased GH secretion in …

The Neuroprotective Effects of Exercise Against Menopause Induced Alterations in Alzheimer’s Disease Neuropathogenesis
… impacts women; and the loss of ovarian hormones during the perimenopausal transition has been identified as a sex-specific risk factor. Previous studies have shown that the ovarian hormone, estrogen, utilizes its neuroprotective effects on tissues in the brain by aiding in …

GABA-A Receptor Subunit Gene Expression as a Biomarker for Perimenstrual Change in Affect and Suicidality
The fluctuating ovarian hormones of the menstrual cycle can influence affective symptoms, with effects ranging from mild, short-term mood changes to severe, debilitating psychiatric symptoms and suicidal ideation (SI). Clinically significant presentations of this phenomenon are prevalent: over half …

Regulation of endometrial repair and its impact on heavy menstrual bleeding
… Endometrial function is governed by the ovarian hormones and pre-menstrually progesterone levels decline as the corpus luteum regresses. Consequently, the synthesis of prostaglandins (PG) is increased, namely PGE2 and the potent vasoconstrictor PGF2α. Subsequent vasoconstriction of …

Elucidation of mammary gland development: combination of novel techniques to study proliferation and stem cells
… postnatally coincident with the production of ovarian hormones in puberty. This capacity of the mammary gland for rapid growth and regeneration has been attributed to mammary stem cells (MaSCs). However, despite extensive efforts over the past 60 years, definitive characterisation of the stem …
