Madvar RR, Taher MA. Preparation of fluorescent sensor based on Zn metal-organic framework for detection and determination of raloxifene as an anticancer drug. ENVIRONMENTAL RESEARCH 2024; 240:117449. [PMID: 37858690 DOI: 10.1016/j.envres.2023.117449] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/09/2023] [Revised: 10/04/2023] [Accepted: 10/17/2023] [Indexed: 10/21/2023]
Abstract
Breast cancer is the second leading cause of death for women worldwide. Raloxifene (RLX) is a somewhat effective drug in lowering cholesterol, preventing and treating invasive breast cancer in postmenopausal women with osteoporosis, and does not interfere with breast tissue. Nevertheless, considering the possibility of risk in biological function due to excessive use of anticancer drugs and the adverse effects of drugs in wastewater on plants, animals, and aquatic, it is useful to determine the concentration of RLX in water and human body fluids. Here, a fluorescent metal-organic framework (MOF) nanoparticle based on trinuclear zinc clusters called Zn-MOF was presented, which is a high-performance and fast-response fluorescent chemosensor that can be used to detect RLX based on the fluorescence quenching medium in water. FTIR, XRD, SEM, and EDS analyses were used to identify the functional group and determine the structure and morphology of Zn-MOF. pH range 3-10. The prepared nanoparticles showed symmetric emission with excitation at a wavelength of 310.0 nm. The performance of the proposed fluorescent nanosensor was proportional to the quenching of the fluorescent signal with increasing RLX concentration at 404.0 nm; the quenching fluorescence response was linear in RLX concentration from 0.7 to 350 ng/mL with a significant detection limit equal to 0.485 nM.

Nitrogen-Based Bisphosphonate Use and Ovarian Cancer Risk in Women Aged 50 Years and Older. J Natl Cancer Inst 2022; 114:878-884. [PMID: 35262727 PMCID: PMC9194625 DOI: 10.1093/jnci/djac050] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2021] [Revised: 01/23/2022] [Accepted: 03/02/2022] [Indexed: 11/13/2022] Open
Abstract
BACKGROUND There are few readily modifiable risk factors for epithelial ovarian cancer; pre-clinical studies suggest bisphosphonates could have chemo-preventive actions. Our study aimed to assess the association between use of nitrogen-based bisphosphonate medicine and risk of epithelial ovarian cancer, overall and by histotype. METHODS We conducted a case-control study nested within a large linked administrative dataset including all Australian women enrolled for Medicare, Australia's universal health insurance scheme, between July 2002 and December 2013. We included all women with epithelial ovarian cancer diagnosed at age 50 years and older between 1st July 2004 and 31st December 2013 (n = 9,367) and randomly selected up to five controls per case, individually matched to cases by age, state of residence, area-level socioeconomic status, and remoteness of residence category (n = 46,830). We used prescription records to ascertain use of nitrogen-based bisphosphonates (ever use and duration of use), raloxifene and other osteoporosis medicines (non-nitrogen-based bisphosphonates, strontium and denosumab). We calculated adjusted odds ratios (OR) and 95% confidence intervals (CI) using conditional logistic regression. RESULTS Ever use of nitrogen-based bisphosphonates was associated with a reduced risk of epithelial ovarian cancer compared to non-use (OR = 0.81, 95%CI : 0.75-0.88). There was a reduced risk of both endometrioid (OR = 0.51, 95%CI : 0.33-0.79) and serous histotypes (OR = 0.84, 95%CI : 0.75-0.93), but no association with the mucinous or clear cell histotypes. CONCLUSION Use of nitrogen-based bisphosphonates was associated with a reduced risk of endometrioid and serous ovarian cancer. This suggests the potential for use for prevention, although validation of our findings is required.

Abstract
Raloxifene (RLX) is a second-generation selective estrogen receptor modulator used to treat osteoporosis in postmenopausal women. RLX fails to be developed into injectable dosage forms due to poor solubility. Although oral formulations are clinically available, the lower bioavailability (<2%) embarrasses the pharmaceutists. This work reported a bioadhesive nanosystem intended for oral delivery of RLX to enhance its oral bioavailability and address the formulation challenge. The bioadhesive nanosystem refers to polymer-lipid hybrid nanoparticles made up of Carbopol 940, glyceryl distearate, and TGPS. RLX was solidly encapsulated into bioadhesive nanoparticles (bNPs) through a nanoprecipitation technique along with synchronous desalting of RLX·HCl. The resultant RLX-loaded bNPs (RLX-bNPs) were characterized by particle size, ζ potential, morphology, and entrapment efficiency. The in vitro release and in vivo oral bioavailability of RLX-bNPs in rats were comparatively investigated with RLX-loaded common lipid nanoparticles (RLX-cNPs). The preferred formulation possesses a particle size of 150 nm around with a polydispersity index (PDI) of 0.282. RLX-bNPs exhibited slower drug release than RLX-cNPs owing to the presence of an adhesive layer. After oral administration, RLX-bNPs resulted in significant enhancement in the bioavailability of RLX, up to 556.9% relative to RLX suspensions, while it was merely 244.7% for RLX-cNPs. Cellular testing and ex vivo transport imaging demonstrated that bNPs were endowed with excellent intestinal epithelial affinity and absorbability. Our study affords an alternative option for designing a suitable oral delivery system specific to amphiphobic drugs like RLX·HCl.

Abstract
Breast cancer and osteoporosis are common diseases that affect the survival and quality of life in postmenopausal women. Women with breast cancer are more likely to develop osteoporosis than women without breast cancer due to certain factors that can affect both diseases simultaneously. For instance, estrogen and the receptor activator of nuclear factor-κB ligand (RANKL) play important roles in the occurrence and development of these two diseases. Moreover, chemotherapy and hormone therapy administered to breast cancer patients also increase the incidence of osteoporosis, and in recent years, neuropeptide Y (NPY) has also been found to impact breast cancer and osteoporosis.Y1 and Y5 receptors are highly expressed in breast cancer, and Y1 and Y2 receptors affect osteogenic response, thus potentially highlighting a potential new direction for treatment strategies. In this paper, the relationship between breast cancer and osteoporosis, the influence of NPY on both diseases, and the recent progress in the research and treatment of these diseases are reviewed.

Combined administration on You-Gui Yin and low-dose Raloxifene partially attenuates the bone loss in ovariectomized mice through the proliferation and osteogenic differentiation of bone marrow stromal cells. PHYTOMEDICINE : INTERNATIONAL JOURNAL OF PHYTOTHERAPY AND PHYTOPHARMACOLOGY 2019; 53:286-293. [PMID: 30668409 DOI: 10.1016/j.phymed.2018.09.014] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/11/2017] [Revised: 07/16/2018] [Accepted: 09/03/2018] [Indexed: 06/09/2023]
Abstract
BACKGROUND Osteoporosis is a systemic skeletal disease of fragility fractures due to the loss of mass and deterioration of the microarchitecture of bone. PURPOSE The aim of the study was to assess the osteogenic effects and the underlying mechanisms of the combined administration of You-Gui Yin (YGY) and Raloxifene hydrochloride (RLX) in ovariectomized (OVX) mice. METHODS First, a classic animal model was used to mimic postmenopausal osteoporosis through the removal of the ovary of mice. Second, the OVX mice were administered YGY, RLX, and YGY + RLX for 12 weeks. Next, the bone microtomographic histomorphometry and bone mineral density (BMD) were assessed by micro-CT, and the biochemical markers of procollagen type I N-terminal propeptide (P1NP) and beta-isomerized C-telopeptide (β-CTX) in serum were assessed. Finally, primary bone marrow stromal cells (BMSCs) were isolated from the tibia and cultured to evaluate cell proliferation and osteogenic differentiation. RESULTS The results showed that BMD on the YGY + RLX group was higher than that on the RLX group (p < 0.05) and did not have a significant difference when compared with the sham group. Notably, the YGY + RLX group had a dramatically increased trabecular number (Tb.N) compared with that of the YGY group (p < 0.05). Moreover, the BV/TV (bone volume/total volume) and Tb.N in the YGY + RLX group were higher than that in the RLX group (p < 0.05), and the Tb.Sp (trabecular separation) was lower than that in the RLX group (p < 0.05). Moreover, the serum level of P1NP from the YGY + RLX group dramatically increased when compared with that from the YGY and RLX groups (YGY group: p < 0.05; RLX groups: p < 0.01). Notably, there was no significant difference between the YGY and YGY + RLX groups. In addition, cell proliferation from the co-administration of YGY and RLX was clearly higher than a single use of YGY and RLX (p < 0.01, respectively). The ALP/BCA (alkaline phosphatase/bicinchoninic acid) in the YGY + RLX group was higher than that in the RLX group (p < 0.01). CONCLUSION Overall, co-administered YGY and RLX could partially attenuate bone loss and were more effective than individually using either one; this outcome might be associated with the proliferation and osteogenic differentiation of BMSCs.

Abstract
Objectives The present mini review aimed to summarize the existing knowledge regarding the beneficial and adverse effects of raloxifene in menopausal women. Methods This study is a review of relevant publications about the effects of raloxifene on sleep disorder, depression, venous thromboembolism, the plasma concentration of lipoprotein, breast cancer, and cognitive function among menopausal women. Results Raloxifene showed no significant effect on depression and sleep disorder. Verbal memory improved with administration of 60 mg/day of raloxifene while a mild cognitive impairment risk reduction by 33% was observed with administration of 120 mg/day of raloxifene. Raloxifene was associated with a 50% decrease in the need for prolapse surgery. The result of a meta-analysis showed a significant decline in the plasma concentration of lipoprotein in the raloxifene group compared to placebo (standardized mean difference, −0.43; 10 trials). A network meta-analysis showed that raloxifene significantly decreased the risk of breast cancer (relative risk, 0.572; 95% confidence interval, 0.327–0.881; P = 0.01). In terms of adverse effects of raloxifene, the odds ratio (OR) was observed to be 1.54 (P = 0.006), indicating 54% increase in the risk of deep vein thrombosis (DVT) while the OR for pulmonary embolism (PE) was 1.05, suggesting a 91% increase in the risk of PE alone (P = 0.03). Conclusions Raloxifene had no significant effect on depression and sleep disorder but decreased the concentration of lipoprotein. Raloxifene administration was associated with an increased risk of DVT and PE and a decreased risk of breast cancer and pelvic organ prolapse in postmenopausal women.

Abstract
Postmenopausal osteoporosis is a systemic skeletal disease of fragility fractures due to the loss of the mass and the deterioration of the microarchitecture of bone. This study aimed to assess the effects of raloxifene hydrochloride nanosuspensions (RLX-NSps) on ovariectomized (OVX)-induced osteoporotic rats, and the underlying mechanisms were also investigated in vivo and ex vivo. RLX-NSps were successfully prepared, and the obtained RLX-NSps had a mean particle size of (91.17 ± 0.73) nm, PDI value of 0.201 ± 0.03 and zeta potential of (36.3 ± 1.8) mV. RLX-NSps showed a clear colloidal solution with light yellow opalescence. RLX-NSps were stable in artificial intestinal fluid, artificial gastric fluid, PBS, isotonic glucose and physiological saline. The OVX mice were administered an RLX-NSps or RLX solution for 3 weeks. The bone micro-tomographic histomorphometry and bone mineral density (BMD) were assessed by micro-CT, and the biochemical markers procollagen type I N-terminal propeptide (P1NP) and beta-isomerized C-telopeptide (β-CTX) were determined from serum. Finally, primary bone marrow stromal cells (BMSCs) were isolated from the tibia and cultured to evaluate cell proliferation and osteogenic differentiation. The results demonstrated that the RLX-NSp group had a better effect on the bone microarchitecture than the RLX solution group. Therefore, RLX-NSps could partially attenuate bone loss more effectively than RLX solution in OVX mice by inhibiting bone resorption and improving the ability of BMSCs to proliferate and their osteogenic differentiation to some extent. Based on these results, nanosuspensions (NSps) may be a promising delivery system for postmenopausal osteoporosis therapy. RLX-NSps could partially attenuate bone loss more effectively than RLX solution in OVX mice by inhibiting bone resorption and improving the ability of BMSCs to proliferate and their osteogenic differentiation to some extent.![]()

Abstract
INTRODUCTION The deleterious effects of letrozole, an aromatase inhibitor, used in the adjuvant treatment of breast cancer in postmenopausal women, on bone are well-documented and represent a major drawback to its clinical use. Raloxifene, a selective estrogen receptor modulator and a clinically approved anti-osteoporotic drug, has been recently demonstrated to be efficacious in women with breast cancer. The present study evaluated the effects of preventive and curative treatment with raloxifene on letrozole-induced alterations of bone microarchitecture and turnover markers in a chemically-induced menopause model in mice. METHOD Swiss strain albino female mice were made menopausal by inducing ovotoxicity using vinyl cyclohexene di epoxide (VCD, 160 mg/kg for 15 days followed by 30 days drug-free period) confirmed by ovarian histology and serum estradiol levels. Effects on femoral and lumbar bones were evaluated by micro CT determination of bone volume, trabecular number, separation, thickness, connective density and trabecular pattern factor and bone turnover markers including ALP, TRAP5b, hydroxyproline and RANKL. In addition to these, markers of Wnt signaling (sclerostin and dickkopf-1) were also evaluated. To rule out the involvement of pharmacokinetic interaction, plasma levels of letrozole and raloxifene were measured following drugs alone and in combination. RESULTS Though bone loss was observed in VCD treated mice (as indicated by micro CT measurements), it was further enhanced with letrozole administration (1 mg/kg) for one month particularly in epiphysis of femoral bones. Raloxifene (15 mg/kg), whether administered concurrently or post-letrozole was able to revert the structural alterations and changes in turnover markers caused by letrozole to varying degrees (p < 0.01 or p < 0.001). Further, estrogen deficiency following letrozole treatment in ovotoxic mice was associated with significant increase in sclerostin and dickkopf-1 in both lumbar and femur bones (p < 0.001) which was attenuated with preventive and curative treatment with raloxifene (p < 0.05). The plasma levels of letrozole remained unaffected by raloxifene administration and vice versa. CONCLUSIONS Our study indicates the potential of raloxifene in preventing and attenuating letrozole-induced bone loss. Further, these effects were found to be independent of a pharmacokinetic interaction between the two drugs.

Abstract
The conjugated estrogen /: bazedoxifene tissue-selective estrogen complex (TSEC) is designed to minimize the undesirable effects of estrogen in the uterus and breast tissues and to allow the beneficial effects of estrogen in other estrogen-target tissues, such as the bone and brain. However, the molecular mechanism underlying endometrial and breast safety during TSEC use is not fully understood. Estrogen receptor α (ERα)-estrogen response element (ERE)-DNA pull-down assays using HeLa nuclear extracts followed by mass spectrometry-immunoblotting analyses revealed that, upon TSEC treatment, ERα interacted with transcriptional repressors rather than coactivators. Therefore, the TSEC-mediated recruitment of transcriptional repressors suppresses ERα-mediated transcription in the breast and uterus. In addition, TSEC treatment also degraded ERα protein in uterine tissue and breast cancer cells, but not in bone cells. Interestingly, ERα-ERE-DNA pull-down assays also revealed that, upon TSEC treatment, ERα interacted with the F-box protein 45 (FBXO45) E3 ubiquitin ligase. The loss-of- and gain-of-FBXO45 function analyses indicated that FBXO45 is involved in TSEC-mediated degradation of the ERα protein in endometrial and breast cells. In preclinical studies, these synergistic effects of TSEC on ERα inhibition also suppressed the estrogen-dependent progression of endometriosis. Therefore, the endometrial and breast safety effects of TSEC are associated with synergy between the selective recruitment of transcriptional repressors to ERα and FBXO45-mediated degradation of the ERα protein.

Abstract
Tamoxifen, a triphenylethylene antiestrogen and one of the first-line endocrine therapies used to treat estrogen receptor-positive breast cancer, has a number of interesting, off-target effects, and among these is the inhibition of sphingolipid metabolism. More specifically, tamoxifen inhibits ceramide glycosylation, and enzymatic step that can adventitiously support the influential tumor-suppressor properties of ceramide, the aliphatic backbone of sphingolipids. Additionally, tamoxifen and metabolites N-desmethyltamoxifen and 4-hydroxytamoxifen, have been shown to inhibit ceramide hydrolysis by the enzyme acid ceramidase. This particular intervention slows ceramide destruction and thereby depresses formation of sphingosine 1-phosphate, a mitogenic sphingolipid with cancer growth-promoting properties. As ceramide-centric therapies are becoming appealing clinical interventions in the treatment of cancer, agents like tamoxifen that can retard the generation of mitogenic sphingolipids and buffer ceramide clearance via inhibition of glycosylation, take on new importance. In this review, we present an abridged, lay introduction to sphingolipid metabolism, briefly chronicle tamoxifen's history in the clinic, examine studies that demonstrate the impact of triphenylethylenes on sphingolipid metabolism in cancer cells, and canvass works relevant to the use of tamoxifen as adjuvant to drive ceramide-centric therapies in cancer treatment. The objective is to inform the readership of what could be a novel, off-label indication of tamoxifen and structurally-related triphenylethylenes, an indication divorced from estrogen receptor status and one with application in drug resistance.

Abstract
Raloxifene has demonstrated anti-estrogen activity in reproductive organs and tissues, but there are very few related studies in cervical cells. The aims of this study is to explore the function of raloxifene in CaSKi cervical cells. We examined the effects of raloxifene on cervical cancer cells exposed to estrogen. The effect of Raloxifene on cell growth, apoptosis was detected. The human papillomavirus (HPV) 16 E6E7 transcription in cervical cell line CaSki cells exposed to 17-estradiol was also examined. Apoptosis was measured by endonucleolytic degradation of DNA. HPV 16 E6E7 was measured by northern analysis. The results indicated that raloxifine inhibits estrogenic promotion activity on growth of CaSki cells. Raloxifene suppresses the proliferation promotion activity of estradiol in CaSki cells. Raloxifene suppresses the stimulation effect of estradiol on HPV 16 E6E7 transcription in CaSki cells. In conclusion, raloxifene inhibit the CaSki cells proliferation induced by estradiol, which suggests that raloxifine also has anti-estrogen activity in cervical cells.

Abstract
We report on a 61-year-old postmenopausal female with schizophrenia included in a raloxifene vs. placebo clinical trial and monitored during a 12-month period including a 3-month withdrawal period (6-9 months) without treatment. The patient was treated with raloxifene 60 mg/day adjuvant to antipsychotic medication for 6 months, medication was then withdrawn for 3 months and was reintroduced due to a worsening of symptoms. We assessed the patient with PANSS and other neuropsychological tests. The patient improved in psychopathology and cognitive level in some aspects related to executive functions. During 3 months without the drug, the patient's condition deteriorated. When the drug was reintroduced, improvements were again observed. Raloxifene may be useful as an adjuvant treatment for psychopathological symptoms and some cognitive aspects in women with chronic schizophrenia.

Abstract
Estrogen deficiency in menopausal women is the main cause of osteoporosis. Phytoestrogen could be a suitable candidate for treatment of post-menopausal osteoporosis. Recent studies showed that S. chinensis contains several lignans, which may be phytoestrogen. In this study, we investigated the ameliorative effects of S. chinensis on post-menopausal osteoporosis. 30% ethanol extract of S. chinensis (SC) was administered orally for 6 weeks after 7 weeks of ovariectomized-induced osteoporosis. Bone mineral density was significantly increased following increased serum osteocalcin levels by SC treatment. Histological analysis showed that SC reduced the increased growth plate of the epiphyseal plate in femur. In addition, pores within bone marrow cells filling the lateral and medial epicondyle were decreased. Serum estradiol concentration was significantly increased in the SC-treated group. The expressions of estrogen receptor-α and -β were increased in uterus and MCF-7 breast cancer cells by SC treatment. And two transcriptions of proto-oncogenes, c-fos and c-Jun, were suppressed by treatment of SC. From these data, we propose that S. chinensis attenuates post-menopausal osteoporosis with its phytoestrogenic effects. S. chinensis may have the potential to be used as an alternative for treatment of osteoporosis.

Abstract
Raloxifene, a second-generation selective estrogen receptor modulator, exerts estrogen-like effects in specific tissues. In this present study, we examined the effect of raloxifene on mesangial cell matrix metalloproteinase-2 (MMP-2) activity in streptozotocin-induced diabetic mice. Raloxifene increased the MMP-2 level in a dose-dependent and receptor-mediated manner. An antibody against estrogen receptor-β (ER-β) blocked the effect of raloxifene on MMP-2 expression, suggesting that the effect of raloxifene on MMP-2 activity was mediated by ER-β. In addition, the transcription factor AP-2, that plays an important role in MMP-2 gene transcription, was overexpressed under raloxifene simulation. The effect of MMP-2 was blocked by a selective inhibitor of the extracellular signal-regulated kinase/mitogen-activated protein kinase (ERK/MAPK) pathway, PD98059. Our results suggested that raloxifene-induced MMP-2 activity increases function through ERK/MAPK signaling via AP-2. In addition, we also found that the effect of raloxifene on MMP-2 expression was mediated via its binding to ER-β. However, at this stage of our investigation, (i) we could only show that both the binding to ER-β and the activation of the ERK/MAPK pathway impacted MMP-2 expression and (ii) we were unable to establish a relationship between ER-β binding and ERK/MAPK pathway activation.

Abstract
Background The treatment of leishmaniasis relies mostly on parenteral drugs with potentially serious adverse effects. Additionally, parasite resistance in the treatment of leishmaniasis has been demonstrated for the majority of drugs available, making the search for more effective and less toxic drugs and treatment regimens a priority for the control of leishmaniasis. The aims of this study were to evaluate the antileishmanial activity of raloxifene in vitro and in vivo and to investigate its mechanism of action against Leishmania amazonensis. Methodology/Principal Findings Raloxifene was shown to possess antileishmanial activity in vitro against several species with EC50 values ranging from 30.2 to 38.0 µM against promastigotes and from 8.8 to 16.2 µM against intracellular amastigotes. Raloxifene's mechanism of action was investigated through transmission electron microscopy and labeling with propidium iodide, DiSBAC2(3), rhodamine 123 and monodansylcadaverine. Microscopic examinations showed that raloxifene treated parasites displayed autophagosomes and mitochondrial damage while the plasma membrane remained continuous. Nonetheless, plasma membrane potential was rapidly altered upon raloxifene treatment with initial hyperpolarization followed by depolarization. Loss of mitochondrial membrane potential was also verified. Treatment of L. amazonensis – infected BALB/c mice with raloxifene led to significant decrease in lesion size and parasite burden. Conclusions/Significance The results of this work extend the investigation of selective estrogen receptor modulators as potential candidates for leishmaniasis treatment. The antileishmanial activity of raloxifene was demonstrated in vitro and in vivo. Raloxifene produces functional disorder on the plasma membrane of L. amazonensis promastigotes and leads to functional and morphological disruption of mitochondria, which culminate in cell death. Cutaneous and visceral leishmaniasis are part of the group we call neglected diseases. They are serious conditions that afflict millions in vast regions of the world. These diseases are very difficult to treat. This is due to the scanty choice of effective drugs together with their potentially severe side effects. One way of finding new treatments for these neglected conditions is to repurpose drugs that are already in use to treat other diseases. In this paper, we show that raloxifene, a drug that is used for the treatment of osteoporosis and also as an alternative in the treatment of breast cancer, is active against the causative agents of leishmaniasis and is effective in the treatment of cutaneous leishmaniasis in an experimental model. We also show that the antileishmanial mechanism of action of raloxifene is related to damage to the cell membrane and to the mitochondrion of the parasite.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is closely correlated with insulin resistance and several metabolic syndrome features, but whether it could increase the risk of cardiovascular disease remains undefined. To assess the association between NAFLD and the risk of cardiovascular outcomes, we systematically searched the MEDLINE, Embase, and the Cochrane Library database (1947 to October 2012) by using Medical Subject Heading search terms and a standardized protocol. Randomized controlled trials, case-control, and prospective studies carried out in human adults, in which the unadjusted and multivariate adjusted odds ratios with corresponding 95% confidence interval (CI) for cardiovascular disease with NAFLD were reported. The search yielded 4 cross-sectional studies and 2 prospective cohort studies including 7,042 participants. The pooled effects estimate showed that NAFLD was a predictor of cardiovascular disease (odds ratio 1.88, 95% CI, 1.68 to 2.01; P < 0.001). The random effects summary estimate indicated that NAFLD retained a significant association with cardiovascular outcomes independent of conventional risk factors after adjustment for established cardiovascular risk factors (odds ratio 1.50, 95% CI, 1.21 to 1.87; P < 0.001). These results indicate that NAFLD is a strong independent predictor of cardiovascular disease and may play a central role in the cardiovascular risk of metabolic syndrome.

Abstract
Sex steroid receptors are ligand-triggered transcription factors. Oestrogen, progesterone and androgen receptors form, together with the glucocorticoid and mineralocorticoid receptors, a subgroup of the superfamily of nuclear receptors. They share a common mode of action, namely translating a hormone-i.e. a small-molecule signal-from outside to changes in gene expression and cell fate, and thereby represent "natural" pharmacological targets.For pharmacological therapy, these receptors have originally been addressed by hormones and synthetic hormone analogues in order to overcome pathologies related to deficiencies in the natural ligands. Another major use for female sex hormone receptor modulators is oral contraception, i.e. birth control.On the other side, blocking the activity of sex steroid receptors has become an established way to treat hormone-dependent malignancies, such as breast and prostate cancer.In this review, we will discuss how the experience gained from the classical pharmacology of these receptors and their molecular similarities led to new options for the treatment of gender-specific diseases and highlight recent progress in medicinal chemistry of sex hormone-modulating drugs.
