It has been proposed that sex steroid hormones improve performance in some cognitive tasks by regulating the basal forebrain cholinergic function. However, the molecular basis of such influence still remains unknown. Current study analyzed the performance of ovariectomized rats in an autoshaping learning task after a short-term treatment with 17β-estradiol(More)
Hormone replacement therapy (HRT) may be prescribed to prevent the symptoms of menopause. This therapy may include estrogenic and/or progestin components and may increase the incidence of endometrial and breast cancers. Tibolone (TIB), which is also made up of estrogen and progestin components, is often used to reduce the impact of HRT. However, the effect(More)
In this work, we determined the variations in the content of the steroid receptor coactivator (SRC-1) and the silencing mediator for retinoic acid and thyroid hormone receptors corepressor (SMRT) in the hypothalamus, the preoptic area, and the hippocampus of adult intact rats during the estrous cycle by Western blot. SRC-1 content changed only in the(More)
Progesterone and estradiol play an important role in the regulation of lung functions such as ventilation and vasoconstriction. The genomic actions of progesterone and estradiol are mediated by their nuclear receptors: progesterone receptors (PR) and estrogen receptors (ER). These actions are linked to interactions between steroid receptors and some(More)
Biotin deficiency and biotin excess have both been found to affect reproduction and cause teratogenic effects. In the reproductive tract, however, the effects of biotin have not been well established yet. We investigated the effects of varying biotin content diets on the oestrus cycle, ovarian morphology, estradiol and progesterone serum levels, and the(More)
Aging is a key risk factor for cognitive decline and age-related neurodegenerative disorders. Also, an age-related decrease in sex steroid hormones may have a negative impact on the formation of neurofibrillary tangles (NFTs); these hormones can regulate Tau phosphorylation and the principal kinase GSK3β involved in this process. Hormone replacement therapy(More)
Sex steroids exert multiple functions in the central nervous system. They modulate responses to olfactory information in mammals but their participation in the regulation of neurotransmission in the olfactory bulb is unknown. We studied by Western blot the effects of estradiol (E2), progesterone (P4), and allopregnanolone (Allo) on the content of glutamic(More)
BACKGROUND The diabetic cardiomyopathy occurs in both type 1 and type 2 diabetes mellitus. Hyperglycemia and associated metabolic changes participate in the pathogenesis of this disease. OBJECTIVE To characterizes various pathological changes occurring during the development of diabetic cardiomyopathy in rats. METHODS Diabetic rats were used for(More)
AIM We studied the estrogen receptor (ER) and progesterone receptor (PR) isoforms expression in gastric antrum and corpus of female gerbils and their regulation by estradiol (E2) and progesterone (P4). METHODS Ovariectomized adult female gerbils were subcutaneously treated with E2, and E2 + P4. Uteri and stomachs were removed, the latter were cut along(More)
