The osteoblast-derived paracrine factor osteoprotegerin (OPG) is considered to play a key role in inhibition of osteoclast formation and activity. Recently, raloxifene, a nonsteroidal benzothiophene, was found to exert anti-resorptive effects via modulating OPG expression in osteoblasts. To explore whether raloxifene regulates bone metabolism via an OPG-dependant pathway in vivo, we investigated the effects of raloxifene on bone loss in Opg-deficient mice. The results show that bone mineral density and bone strength are increased in mice deficient for Opg after treatment with raloxifene for 30 days. Histomorphometric analysis shows that raloxifene can increase bone trabecular area and decrease the number of osteoclasts in Opg (-/-) mice. Moreover, raloxifene reduces Rankl transcription and serum level of Rankl, which is dramatically increased in Opg knockout mice. These results suggest that raloxifene-induced inhibition of bone resorption may be independent of Opg pathway in mice.

Raloxifene, a selective estrogen receptor modulator, is estrogen-like in the skeleton and cardiovascular system and antiestrogenic in reproductive tissues. In contrast to estrogens, raloxifene is not indicated for the treatment of hot flashes. This study was designed to examine the characteristics of hot flashes among healthy postmenopausal women participating in osteoporosis prevention trials who were receiving raloxifene or placebo.

Tamoxifen had an oestrogen receptor dependent, direct, inhibitory effect on human osteoclast differentiation and bone resorption, whereas ospemifene and raloxifene required osteoblastic cells to achieve a similar inhibition. The effects of ospemifene and raloxifene were mediated by oestrogen receptors by a mechanism involving paracrine induction of osteoprotegerin in cultures with osteoblast derived osteosarcoma cells.

This study examined patients' risk profiles and adherence to treatment in relation to the effect of risedronate and raloxifene on hip fracture incidence. Administrative billing data were used to follow two cohorts of women aged 65 and older after starting therapy with either risedronate (n = 86,735) or raloxifene (n = 37,726). The fracture risk profile was described using a 6-month history period before starting therapy. Effectiveness of each therapy was evaluated by comparing the incidence of hip fractures during the first 3 months with the subsequent 12 months among women adherent (medication possession ratio >80%) compared with those non-adherent to treatment. At the start of therapy, the raloxifene cohort was younger than the risedronate cohort (median age 73 vs. 76 years) and had fewer prior fractures (p < 0.01 for both). In the first 3 months of therapy, hip fracture incidence was lower in the raloxifene group (0.51 per 100 person-years) compared with the risedronate group (0.94 per 100 person-years). In the subsequent 12 months, the incidence of hip fractures decreased among patients adherent to the risedronate regimen [relative risk (RR) 0.70, 95% CI 0.59-0.84, p < 0.01] and did not change significantly among patients adherent to the raloxifene regimen (RR 1.02, 95% CI 0.73-1.44). In poorly adherent patients, neither drug decreased hip fracture risk. Risedronate treatment in adherent patients rapidly decreased the risk of hip fractures, whereas raloxifene treatment did not.

Estrogens have cell-specific effects on a variety of physiological endpoints including regulation of mitochondrial biogenesis and activity. Estrogens regulate gene transcription by the classical genomic mechanism of binding to estrogen receptors alpha and beta (ERalpha and ERbeta) as well as the more recently described nongenomic pathways involving plasma membrane-associated ERs that activate intracellular protein kinase-mediated phosphorylation signaling cascades. Here I evista buy will review the rapid and longer-term effects of estrogen on mitochondrial function. The identification of ERalpha and ERbeta within mitochondria of various cells and tissues is discussed with a model of estrogen regulation of the transcription of nuclear respiratory factor-1 (NRF-1, NRF1). NRF-1 subsequently promotes transcription of mitochondrial transcription factor Tfam (mtDNA maintenance factor, also called mtTFA) and then Tfam targets mtDNA-encoded genes. The nuclear effects of estrogens on gene expression directly controlling mitochondrial biogenesis, oxygen consumption, mtDNA transcription, and apoptosis are reviewed. Overall, we are just beginning to evaluate the many direct and indirect effects of estrogens on mitochondrial activities.

Hormone replacement therapy has been implicated in the increased incidence of breast cancer, although selective estrogen receptor modulators have been shown to be effective in the prevention of breast cancer. Breast cancers are associated with increased mammary blood flow compared to benign breast lesions. However, few studies have examined the hemodynamic effects of hormonal agents on the mammary circulation that promote or reduce the risk of breast cancers. Although estradiol-17beta has been shown to increase mammary blood flow, the effect of selective estrogen receptor modulators remains undetermined. We therefore compared the vascular effects of selective Vasotec Drug Card estrogen receptor modulators and estrogens on mammary blood flow.

In the 1960s, compounds known as nonsteroidal antiestrogens were identified as potential contraceptives, but the drugs caused the induction of ovulation in subfertile women. Tamoxifen and clomiphene were marketed for this indication. However, tamoxifen was advanced for the treatment of breast cancer in the 1970s through a close cooperation between the laboratory and the clinical trials community. The extensive use of long-term adjuvant tamoxifen has resulted in saving the lives of 400,000 women with breast cancer. Tamoxifen is a selective estrogen receptor modulator (SERM) that produces antiestrogenic actions in the breast but estrogen-like actions in bone and lowers serum cholesterol. These properties not only allowed the application of tamoxifen as the first chemopreventive in high-risk pre- and postmenopausal women but also the development of raloxifene to prevent osteoporosis with the potential to prevent breast cancer in postmenopausal women. The future development of Nexium Reviews 2014 SERMs holds the promise of preventing osteoporosis and coronary heart disease as well as breast and endometrial cancer.

This prospective randomized single-blind placebo-controlled clinical trial was carried out to evaluate the effects of raloxifene administration on uterine and leiomyoma sizes in premenopausal women. Ninety healthy premenopausal women affected by asymptomatic uterine leiomyomas were enrolled and treated with raloxifene at the doses of 60 mg/d (group A), 180 mg/d (group B), or placebo (group C). The duration of the treatment was 6 cycles of 28 d each. At entry and after three and six cycles, uterine and leiomyoma sizes were measured by transvaginal ultrasonography. The difference between uterine and leiomyoma volumes (Delta size) was calculated in all subjects. The characteristics of the menstrual cycles and the side effects of the treatments were recorded using a daily diary. The severity of the uterine bleedings was assessed using a rank scale. Throughout the study, no significant changes were observed in uterine Strattera Cost Canada and leiomyoma size or in Delta size among the three groups and within each group of treatment. The length and severity of uterine bleedings was not significantly different between the three groups and within each group. In conclusion, raloxifene has no significant effect on uterine and leiomyoma size or on menstrual cycle in premenopausal women.

In men, the stimulation of GH and inhibition of LH secretion by testosterone requires aromatization to estradiol. Tamoxifen, a selective estrogen receptor modulator (SERM), possesses central estrogen antagonistic effect but peripheral hepatic agonist effect, lowering IGF-I. Thus, tamoxifen is likely to perturb the neuroendocrine regulation of GH and gonadal axes. Raloxifene, a SERM, is used for therapy of osteoporosis in both sexes. Its neuroendocrine effects in men are poorly understood.

We have isolated a highly expressed splice variant mRNA of murine estrogen receptor-beta (ERbeta), mERbeta2, containing an in-frame 54 nucleotide insertion between exons 5 and 6 of wild-type mERbeta1. The predicted ERbeta2 protein contains 18 amino acids inserted in the ligand binding domain of mERbeta1. Recombinant protein generated by in vitro transcription/translation showed that mERbeta2 had markedly reduced ligand binding (K(D)=17.7+/-4.7 nM, mean+/-s.e.m., n=3) compared with mERbeta1-bound (3)H-estradiol (K(D)=0.56+/- 0.19 nM, mean+/-s.e.m., n=3). Both receptors bound similarly to palindromic estrogen responsive elements (EREs) in vitro and in vivo, and similarly bent DNA. Transcriptional activity was assessed using transient transfection analysis into a homologous murine cell line, NIH 3T3 cells. mERbeta1 transactivated ERE-tk-CAT reporter genes similarly to mERalpha, whereas mERbeta2 had little activity except at high ligand concentrations. However, under conditions in which mERbeta2 is unlikely to be ligand saturated, co-transfected mERbeta2 inhibited activity of mERalpha and possibly mERbeta1 on ERE-tk-CAT genes. Using a 'novel raloxifene responsive' gene reporter system (TGF-beta3-CAT), we found the ability of estradiol and LY117018 to activate both mERalpha and mERbeta1 on this promoter was identical, and mERbeta2 activity in the presence of either estradiol or LY117018 was only slightly less than that observed with either mERbeta1 or mERalpha. Both mERbeta1 and mERbeta2 when liganded with LY117018 inhibited transcription at a classical ERE-regulated promoter under these transfection conditions, which was in marked contrast to their stimulatory effect at the transforming growth factor-beta3 promoter. These data suggest that responsiveness of gene expression to a relatively highly expressed variant murine ERbeta isoform, mERbeta2, is both ligand and promoter specific. Determination of the relative level of expression of mERbeta1 mRNA and mERbeta2 mRNA in mouse tissues indicated predominance of mERbeta2 mRNA in some but not all tissues. These data suggest that the mERbeta2 may have some tissue-specific and promoter-specific modulatory effects.

Covalent binding of reactive metabolites to cytochrome P450s (P450s) often causes their mechanism-based inactivation (MBI), resulting in drug-drug interactions or toxicity. The detection and identification of the P450 sites to which reactive metabolites bind would elucidate MBI mechanisms. We describe a proteomic approach using nano-LC/linear ion trap-Fourier transform ion cyclotron resonance (FTICR) mass spectrometry to characterize the binding of a reactive metabolite of raloxifene, which is a known P450 3A4 inhibitor, to the P450 3A4 isozyme. LTQ-FT analyses revealed that the metabolic reaction of raloxifene in a reconstituted P450 3A4 system formed a reactive metabolite adduct to P450 3A4 apoprotein, accompanied by a mass shift of 471 Da relative to intact P450 3A4 apoprotein. The reaction mixtures were digested with trypsin, and then the tryptic digests were analyzed by nano-LC-MS/MS. This technique revealed that VWGFYDGQQPVLAITDPDMIK (position 71-91) was a tryptic peptide modified by the reactive metabolite derived from raloxifene. The site of adduction with the reactive metabolite was further postulated to be the nucleophilic OH group of Tyr-75 of P450 3A4. A proteomic approach using LTQ-FT can yield direct information on the P450 3A4 modification site without radiolabeled compounds. In addition, this information can elucidate mechanisms involved in the covalent binding of reactive metabolites and the inactivation of P450 3A4.

Estradiol and some selective estrogen receptor modulators (SERMs) are neuroprotective in a variety of experimental models of neurodegeneration, reduce the inflammatory response of glial cells, reduce anxiety and depression, promote cognition and modulate synaptic plasticity in the hippocampus of rodents. In this study we have assessed whether estradiol and two SERMs currently used in clinics, tamoxifen and raloxifene, affect medial prefrontal cortex function and morphology. Rats were ovariectomized and six days later some animals received a subcutaneous injection of the estrogenic compounds. In a first experiment animals were treated with estradiol benzoate or sesame oil vehicle. In a second experiment animals received raloxifene, tamoxifen or dimethyl sulfoxide as vehicle. Twenty four hours after the pharmacological treatment, animals were challenged to solve an allocentric working memory paradigm in a "Y" maze. Twenty trials consisting of a study phase and a test phase were conducted according to a delayed match-to-sample procedure in a single one-day session. Animals that were not submitted to behavioral test were used for Golgi analysis of the prefrontal cortex. Rats treated with estradiol benzoate, tamoxifen or raloxifene performed better in the Y maze and showed a significant increase in the numerical density of dendritic spines in secondary apical dendrites of layer III pyramidal neurons from the prelimbic/infralimbic prefrontal cortex, compared to their respective control groups. These findings suggest that estradiol, tamoxifen and raloxifene improve prefrontal cortex-related cognitive performance and modulate prefrontal cortex morphology in ovariectomized rats.

The dose-dependent effect of a 24 h treatment with estradiol (E(2)) (1, 2, 5, 10 nM) and raloxifene (Rx) (1, 5, 10, 20 microM) on ER alpha and ER beta mRNA expression, collagen bio-synthesis, prolidase activity, MMP-2, MMP-9, insulin-like growth factor I receptor expression (IGF-1R) and beta1-integrin expressions in cultured fibroblasts obtained from postmenopausal women were examined. Both ligands increased mRNA expression of ER compared to control. Rx at 5 and 10 microM concentrations had greater stimulative effect on collagen biosynthesis, prolidase activity and IGF-1R expression compared to E(2) at 2 and 5 nM concentration. Both studied ER ligands had no effect on beta1-integrin receptor expressions. MMP-2 expression was not detected in human skin fibroblast culture. In contrast to estradiol raloxifene inhibited the expression of MMP-9. Raloxifene had stronger positive stimulative effects on collagen biosynthesis, through different biochemical mechanisms, than estradiol in human skin fibroblasts and might reverse some of the postmenopausal changes in skin or connective tissue. Increase of collagen synthesis induced by raloxifene may be activated by both estrogen receptor dependent and independent pathways such as up-regulation of estrogen receptors, up-regulation of IGF receptor, transcriptional regulation of collagen genes by estrogen receptor-raloxifene complex, increasing of prolidase activity or finally by inhibition of MMP-9 expression.

The reasons for non-compliance were a fear of side effects and high drug price in 6 (30%) and 4 (20%) patients respectively in the raloxifene group, and inconvenience caused by medication use in 3 patients (14.3%) in the alendronate group. Logistic regression analysis of factors that may influence compliance included age, previous fractures, family history of osteoporosis, bone density T-score less than -2.5, and presence and number of concomitant diseases. Age was the only statistically significant parameter in this model: 67.8 +/- 8.8 in non-compliant versus 64.11 +/- 7.4 in compliant patients (P = 0.029).

The direct effects of keoxifene (LY 156758), a benzothiphene-derived antiestrogen, on granulosa cell differentiation were examined in vitro using primary cultures of rat granulosa cells. The effect of keoxifene on FSH-stimulated aromatase activity was biphasic in pattern, enhancing at lower concentrations (up to 10(-8) M), and inhibiting at higher concentrations (greater than 10(-6) M). Keoxifene inhibited FSH-stimulated progestin production in a dose-dependent fashion with an IC50 of 5 X 10(-8) M. FSH-induced LH receptors were also inhibited by keoxifene with an IC50 of 5 X 10(-7) M. These findings suggest that keoxifene has direct pharmacologic actions at the ovarian level. In contrast to the earlier reported estrogenic actions of triphenylethylene antiestrogens at the ovarian level, the benzothiphene-derived antiestrogens may be clinically more useful in the management of estrogen-dependent malignancies.

While it is obvious that patients should be involved in the decision making process, questions arise as to whether it is feasible to inform them objectively.
