Abstract
The aetiology of heart failure with preserved ejection fraction (HFpEF) is heterogenous and overlaps with that of several comorbidities like atrial fibrillation, diabetes mellitus, chronic kidney disease, valvular heart disease, iron deficiency, or sarcopenia. The diagnosis of HFpEF involves evaluating cardiac dysfunction through imaging techniques and assessing increased left ventricular filling pressure, which can be measured directly or estimated through various proxies including natriuretic peptides. To better narrow down the differential diagnosis of HFpEF, European and American heart failure guidelines advocate the use of different algorithms including comorbidities that require diagnosis and rigorous treatment during the evaluation process. Therapeutic recommendations differ between guidelines. Whilst sodium glucose transporter 2 inhibitors have a solid evidence base, the recommendations differ with regard to the use of inhibitors of the renin-angiotensin-aldosterone axis. Unless indicated for specific comorbidities, the use of beta-blockers should be discouraged in HFpEF. The aim of this article is to provide an overview of the current state of the art in HFpEF diagnosis, clinical evaluation, and treatment.

Abstract
AIMS Recent trial data demonstrate beneficial effects of active rhythm management in patients with atrial fibrillation (AF) and support the concept that a low arrhythmia burden is associated with a low risk of AF-related complications. The aim of this document is to summarize the key outcomes of the 9th AFNET/EHRA Consensus Conference of the Atrial Fibrillation NETwork (AFNET) and the European Heart Rhythm Association (EHRA). METHODS AND RESULTS Eighty-three international experts met in Münster for 2 days in September 2023. Key findings are as follows: (i) Active rhythm management should be part of the default initial treatment for all suitable patients with AF. (ii) Patients with device-detected AF have a low burden of AF and a low risk of stroke. Anticoagulation prevents some strokes and also increases major but non-lethal bleeding. (iii) More research is needed to improve stroke risk prediction in patients with AF, especially in those with a low AF burden. Biomolecules, genetics, and imaging can support this. (iv) The presence of AF should trigger systematic workup and comprehensive treatment of concomitant cardiovascular conditions. (v) Machine learning algorithms have been used to improve detection or likely development of AF. Cooperation between clinicians and data scientists is needed to leverage the potential of data science applications for patients with AF. CONCLUSIONS Patients with AF and a low arrhythmia burden have a lower risk of stroke and other cardiovascular events than those with a high arrhythmia burden. Combining active rhythm control, anticoagulation, rate control, and therapy of concomitant cardiovascular conditions can improve the lives of patients with AF.

Abstract
Tissue engineering with human cardiac fibroblasts (CF) allows identifying novel mechanisms and anti-fibrotic drugs in the context of cardiac fibrosis. However, substantial knowledge on the influences of the used materials and tissue geometries on tissue properties and cell phenotypes is necessary to be able to choose an appropriate model for a specific research question. As there is a clear lack of information on how CF react to the mold architecture in engineered connective tissues (ECT), we first compared the effect of two mold geometries and materials with different hardnesses on the biomechanical properties of ECT. We could show that ECT, which formed around two distant poles (non-uniform model) were less stiff and more strain-resistant than ECT, which formed around a central rod (uniform model), independent of the materials used for poles and rods. Next, we investigated the cell state and could demonstrate that in the uniform versus non-uniform model, the embedded cells have a higher cell cycle activity and display a more pronounced myofibroblast phenotype. Differential gene expression analysis revealed that uniform ECT displayed a fibrosis-associated gene signature similar to the diseased heart. Furthermore, we were able to identify important relationships between cell and tissue characteristics, as well as between biomechanical tissue parameters by implementing cells from normal heart and end-stage heart failure explants from patients with ischemic or dilated cardiomyopathy. Finally, we show that the application of pro- and anti-fibrotic factors in the non-uniform and uniform model, respectively, is not sufficient to mimic the effect of the other geometry. Taken together, we demonstrate that modifying the mold geometry in tissue engineering with CF offers the possibility to compare different cellular phenotypes and biomechanical tissue properties.

Abstract
BACKGROUND Aging is associated with a progressive reduction in cellular function leading to poor health and loss of physical performance. Mitochondrial dysfunction is one of the hallmarks of aging; hence, interventions targeting mitochondrial dysfunction have the potential to provide preventive and therapeutic benefits to elderly individuals. Meta-analyses of age-related gene expression profiles showed that the expression of Ahnak1, a protein regulating several signal-transduction pathways including metabolic homeostasis, is increased with age, which is associated with low VO2MAX and poor muscle fitness. However, the role of Ahnak1 in the aging process remained unknown. Here, we investigated the age-related role of Ahnak1 in murine exercise capacity, mitochondrial function, and contractile function of cardiac and skeletal muscles. METHODS We employed 15- to 16-month-old female and male Ahnak1-knockout (Ahnak1-KO) and wild-type (WT) mice and performed morphometric, biochemical, and bioenergetics assays to evaluate the effects of Ahnak1 on exercise capacity and mitochondrial morphology and function in cardiomyocytes and tibialis anterior (TA) muscle. A human left ventricular (LV) cardiomyocyte cell line (AC16) was used to investigate the direct role of Ahnak1 in cardiomyocytes. RESULTS We found that the level of Ahnak1 protein is significantly up-regulated with age in the murine LV (1.9-fold) and TA (1.8-fold) tissues. The suppression of Ahnak1 was associated with improved exercise tolerance, as all aged adult Ahnak1-KO mice (100%) successfully completed the running programme, whereas approximately 31% male and 8% female WT mice could maintain the required running speed and distance. Transmission electron microscopic studies showed that LV and TA tissue specimens of aged adult Ahnak1-KO of both sexes have significantly more enlarged/elongated mitochondria and less small mitochondria compared with WT littermates (P < 0.01 and P < 0.001, respectively) at basal level. Further, we observed a shift in mitochondrial fission/fusion balance towards fusion in cardiomyocytes and TA muscle from aged adult Ahnak1-KO mice. The maximal and reserve respiratory capacities were significantly higher in cardiomyocytes from aged adult Ahnak1-KO mice compared with the WT counterparts (P < 0.05 and P < 0.01, respectively). Cardiomyocyte contractility and fatigue resistance of TA muscles were significantly increased in Ahnak1-KO mice of both sexes, compared with the WT groups. In vitro studies using AC16 cells have confirmed that the alteration of mitochondrial function is indeed a direct effect of Ahnak1. Finally, we presented Ahnak1 as a novel cardiac mitochondrial membrane-associated protein. CONCLUSIONS Our data suggest that Ahnak1 is involved in age-related cardiac and skeletal muscle dysfunction and could therefore serve as a promising therapeutical target.

Abstract
INTRODUCTION Skeletal muscle wasting is a frequent clinical problem encountered in patients with chronic diseases. Increased levels of inflammatory markers play a role in the imbalance between muscle protein synthesis and degradation. Although testosterone has long been proposed as a treatment for patients with muscle wasting, undesirable side effects have raised concerns about prostatic hypertrophy in men as well as virilization in women. Selective androgen receptor modulators (SARMs) have demonstrated similar results like testosterone at improving lean body mass (LBM) with less side effects on androgen-dependent tissue. AREAS COVERED This review outlines the ongoing clinical development in the field of SARMs and their effectiveness in improving body composition and physical function. The included articles were collected at pubmed.gov and analyzed integrally. EXPERT OPINION There is an unmet clinical need for safe and effective anabolic compounds such as SARMs. Despite the effect on LBM shown by SARMs in phase II clinical trials, results on improved physical function and muscle strength are still lacking and long-term outcomes have to be assessed in these patients. Moreover, there is a need to determine the effect of resistance exercise training and protein intake associated with SARMs in the treatment of patients with muscle wasting.

Aims Sex differences in cardiac fibrosis point to the regulatory role of 17β-Estradiol (E2) in cardiac fibroblasts (CF). We, therefore, asked whether male and female CF in rodent and human models are differentially susceptible to E2, and whether this is related to sex-specific activation of estrogen receptor alpha (ERα) and beta (ERβ). Methods and results In female rat CF (rCF), 24 h E2-treatment (10-8 M) led to a significant down-regulation of collagen I and III expression, whereas both collagens were up-regulated in male rCF. E2-induced sex-specific collagen regulation was also detected in human CF, indicating that this regulation is conserved across species. Using specific ERα- and ERβ-agonists (10-7 M) for 24 h, we identified ERα as repressive and ERβ as inducing factor in female and male rCF, respectively. In addition, E2-induced ERα phosphorylation at Ser118 only in female rCF, whereas Ser105 phosphorylation of ERβ was exclusively found in male rCF. Further, in female rCF we found both ER bound to the collagen I and III promoters using chromatin immunoprecipitation assays. In contrast, in male rCF only ERβ bound to both promoters. In engineered connective tissues (ECT) from rCF, collagen I and III mRNA were down-regulated in female ECT and up-regulated in male ECT by E2. This was accompanied by an impaired condensation of female ECT, whereas male ECT showed an increased condensation and stiffness upon E2-treatment, analysed by rheological measurements. Finally, we confirmed the E2-effect on both collagens in an in vivo mouse model with ovariectomy for E2 depletion, E2 substitution, and pressure overload by transverse aortic constriction. Conclusion The mechanism underlying the sex-specific regulation of collagen I and III in the heart appears to involve E2-mediated differential ERα and ERβ signaling in CFs.

Abstract
Numerous epidemiological, clinical, and animal studies showed that cardiac function and manifestation of cardiovascular diseases (CVDs) are different between males and females. The underlying reasons for these sex differences are definitely multifactorial, but major evidence points to a causal role of the sex steroid hormone 17β-estradiol (E2) and its receptors (ER) in the physiology and pathophysiology of the heart. Interestingly, it has been shown that cardiac calcium (Ca2+) ion channels and mitochondrial function are regulated in a sex-specific manner. Accurate mitochondrial function and Ca2+ signaling are of utmost importance for adequate heart function and crucial to maintaining the cardiovascular health. Due to the highly sensitive nature of these processes in the heart, this review article highlights the current knowledge regarding sex dimorphisms in the heart implicating the importance of E2 and ERs in the regulation of cardiac mitochondrial function and Ca2+ ion channels, thus the contractility. In particular, we provide an overview of in-vitro and in-vivo studies using either E2 deficiency; ER deficiency or selective ER activation, which suggest that E2 and ERs are strongly involved in these processes. In this context, this review also discusses the divergent E2-responses resulting from the activation of different ER subtypes in these processes. Detailed understanding of the E2 and ER-mediated molecular and cellular mechanisms in the heart under physiological and pathological conditions may help to design more specifically targeted drugs for the management of CVDs in men and women.

Abstract
Women and men, female and male animals and cells are biologically different, and acknowledgement of this fact is critical to advancing medicine. However, incorporating concepts of sex-specific analysis in basic research is largely neglected, introducing bias into translational findings, clinical concepts and drug development. Research funding agencies recently approached these issues but implementation of policy changes in the scientific community is still limited, probably due to deficits in concepts, knowledge and proper methodology. This expert review is based on the EUGenMed project (www.eugenmed.eu) developing a roadmap for implementing sex and gender in biomedical and health research. For sake of clarity and conciseness, examples are mainly taken from the cardiovascular field that may serve as a paradigm for others, since a significant amount of knowledge how sex and oestrogen determine the manifestation of many cardiovascular diseases (CVD) has been accumulated. As main concepts for implementation of sex in basic research, the study of primary cell and animals of both sexes, the study of the influence of genetic vs. hormonal factors and the analysis of sex chromosomes and sex specific statistics in genome wide association studies (GWAS) are discussed. The review also discusses methodological issues, and analyses strength, weaknesses, opportunities and threats in implementing sex-sensitive aspects into basic research.

Abstract
Biological sex significantly affects the presentation, outcome of treatment and progression of disease. However, the role of sex has yet underestimated consequences for physiology and pathology. We put forward that a better understanding of the effects of sex in pathophysiology and the underlying mechanisms is necessary. This may facilitate the identification of targets that respond to specific therapies, thereby contributing towards a more appropriate and individualised medical care for both men and women.

The reasons for sex differences in CVD are definitely multifactorial, but major evidence points to the contribution of sex steroid hormone, 17β-estradiol (E2), and its receptors, estrogen receptor alpha (ERα) and estrogen receptor beta (ERβ). In this review, we summarize past and present studies that implicate E2 and ER as important determinants of sexual dimorphism in the physiology and pathophysiology of the heart. In particular, we give an overview of studies aimed to reveal the role of E2 and ER in the physiology of the observed sex differences in CVD using ER knock-out mice. Finally, we discuss recent findings from novel transgenic mouse models, which have provided new information on the sexual dimorphic roles of ER specifically in cardiomyocytes under pathological conditions.

Abstract
Background Estrogen improves cardiac recovery after ischemia/reperfusion (I/R) by yet incompletely understood mechanisms. Mitochondria play a crucial role in I/R injury through cytochrome c-dependent apoptosis activation. We tested the hypothesis that 17β-estradiol (E2) as well as a specific ERβ agonist improve cardiac recovery through estrogen receptor (ER)β-mediated mechanisms by reducing mitochondria-induced apoptosis and preserving mitochondrial integrity. Methods We randomized ovariectomized C57BL/6N mice 24h before I/R to pre-treatment with E2 or a specific ERβ agonist (ERβA). Isolated hearts were perfused for 20min prior to 30min global ischemia followed by 40min reperfusion. Results Compared with controls, ERβA and E2 treated groups showed a significant improvement in cardiac recovery, i.e. an increase in left ventricular developed pressure, dP/dtmax and dP/dtmin. ERβA and E2 pre-treatment led to a significant reduction in apoptosis with decreased cytochrome c release from the mitochondria and increased mitochondrial levels of anti-apoptotic Bcl2 and ACAA2. Protein levels of mitochondrial translocase inner membrane (TIM23) and mitochondrial complex I of respiratory chain were increased by ERβA and E2 pre-treatment. Furthermore, we found a significant increase of myosin light chain 2 (MLC2) phosphorylation together with ERK1/2 activation in E2, but not in ERβA treated groups. Conclusions Activation of ERβ is essential for the improvement of cardiac recovery after I/R through the inhibition of apoptosis and preservation of mitochondrial integrity and can be a achieved by a specific ERβ agonist. Furthermore, E2 modulates MLC2 activation after I/R independent of ERβ.

Abstract
Objectives:
Female pressure-overloaded hearts show less fibrosis compared with males. 17β-Estradiol (E2) attenuates cardiac fibrosis in female mice. Whether this is mediated by direct E2-effects on collagen synthesis is still unknown. Therefore, we investigated the role of E2 and estrogen receptors (ER) on collagen I and III expression and analyzed involved mechanisms.
Methods:
Female C57BL/6J mice (7 weeks) underwent sham operation, ovariectomy (OVX), OVX with E2-supplementation (390mg E2-containing pellets) or placebo. After 2 weeks, animals underwent transverse aortic constriction (TAC) or sham surgery. Mice were sacrificed after 9 weeks. Collagen amount, collagen I and III protein in left ventricular tissue were detected by Sirius Red and antibody staining, respectively. Gene and protein expression were determined by quantitative Real-Time PCR and Western blot. Adult female rat cardiac fibroblasts were treated with E2 (10
-8
M), vehicle, ERα- and β-agonists (10
-7
M) for 24h or pre-treated with PD98059 for 1h. ER binding to the collagen I and III promoter was analyzed by chromatin immunoprecipitation assays.
Findings:
In female OVX mice, undergoing TAC surgery, E2-supplementation significantly reduced collagen deposition, collagen I and III mRNA and protein levels in comparison with mice without E2. In female rat cardiac fibroblasts, E2 significantly down-regulated collagen I and III mRNA and protein level. Specific ER-agonist-treatment showed that E2-mediated regulation of collagen I and III expression was mediated via activation of ERα, but not ERβ. Further, upon E2-treatment, ERα was phosphorylated at Ser118, which occurred by E2-induced activation of ERK1/2 signaling. Furthermore, we could show that ERα and ERβ bind to two putative half-palindromic estrogen response elements within the collagen I and III promoter in female cardiac fibroblasts.
Conclusion:
E2 inhibits cardiac collagen I and III mRNA and protein in female mice under pressure overload. Data from rat female cardiac fibroblasts suggest that this is mediated via E2-activated ERK1/2 signaling and ERα, which binds with ERβ to the collagen I and III promoter. Understanding of how E2/ER attenuate collagen I and III expression in pathological hypertrophy may improve therapy.

Abstract
Experimental studies showed that 17β-estradiol (E2) and activated Estrogen Receptors (ER) protect the heart from ischemic injury. However, the underlying molecular mechanisms are not well understood. To investigate the role of ER-alpha (ERα) in cardiomyocytes in the setting of myocardial ischemia, we generated transgenic mice with cardiomyocyte-specific overexpression of ERα (ERα-OE) and subjected them to Myocardial Infarction (MI). At the basal level, female and male ERα-OE mice showed increased Left Ventricular (LV) mass, LV volume and cardiomyocyte length. Two weeks after MI, LV volume was significantly increased and LV wall thickness decreased in female and male WT-mice and male ERα-OE, but not in female ERα-OE mice. ERα-OE enhanced expression of angiogenesis and lymphangiogenesis markers (Vegf, Lyve-1), and neovascularization in the peri-infarct area in both sexes. However, attenuated level of fibrosis and higher phosphorylation of JNK signaling pathway could be detected only in female ERα-OE after MI. In conclusion, our study indicates that ERα protects female mouse cardiomyocytes from the sequelae of ischemia through induction of neovascularization in a paracrine fashion and impaired fibrosis, which together may contribute to the attenuation of cardiac remodelling.

Abstract
BACKGROUND In pressure overload, profibrotic gene expression and cardiac fibrosis are more pronounced in males than in females. Sex-specific and estrogen-dependent regulation of microRNAs (miRNAs), such as miR-21, may be a potential mechanism leading to sex differences in fibrosis. OBJECTIVES To analyze the influence of sex, estrogen, and estrogen receptor beta (ERβ) on the expression of miR-21 and to identify additional miRNAs potentially involved in sex-specific pressure overload-induced cardiac remodeling. METHODS The sex-specific regulation of fibrosis-related miRNAs was analyzed in male and female wild type and ERβ-deficient mice after transverse aortic constriction (TAC), in rat fibroblasts, and in a cardiomyocyte-like cell line. RESULTS We report the sex-specific expression of functionally-related miR-21, -24, -27a, -27b, 106a, -106b and the regulation of their expression by estrogen in a sex-specific manner. These effects were abolished in ERβ-deficient mice. We demonstrate the presence of common functional target sites for these miRNAs on three repressors of the mitogen-activated protein kinase signaling pathway, i.e. Rasa1, Rasa2 and Spry1, which may all lead to cardiac fibrosis. As expected, transfection with miRNA mimics targeting these repressors induced ERK1/2 phosphorylation. CONCLUSIONS Estrogen regulates a network of miRNAs in a sex-specific manner via ERβ. Our data suggest that the sex-specific expression of these miRNAs may be related to sex differences in fibrosis after pressure overload.

Abstract
Clinical and animal studies showed in female pressure-overloaded hearts less cardiac fibrosis and collagen I and III gene expression compared to males, suggesting an inhibitory effect of 17β-Estradiol (E2) on collagens. Therefore we investigated the role of E2 and estrogen receptors (ER) on collagen I and III expression in isolated rat cardiac fibroblasts from both sexes.
Cardiac fibroblasts were isolated from adult male and female Wistar rats, and treated with E2 (10-8M), vehicle, ERα and ERβ-agonist (10-7M) and/or pre-treated with ICI 182,780 (10-5M) for 24h. Cellular localization of ER in cardiac fibroblasts with/without E2 was detected by immunofluorescence staining, and expression of both ER was determined by western blot. Expression of collagen I and III was determined by qRT-PCR and western blot.
E2-treatment led to a nuclear translocation of ERα and ERβ in cardiac fibroblasts, suggesting the functional activity of ER as transcription factors. Furthermore in cardiac fibroblasts from female rats E2 led to a significant down-regulation of collagen I and III gene and protein expression. In contrast there was a significant increase of collagen I and III levels in fibroblasts isolated from male rat hearts by E2. E2-effect could be inhibited by ICI 182, 780 indicating the involvement of ER. In cardiac fibroblasts from female rats, ERα-agonist treatment led to a significant down-regulation of collagen I and III mRNA level, but ERβ-agonist had no effects. In contrast, ERβ-agonist treatment of cardiac fibroblasts from males increased collagen I and III mRNA, but no changes with ERα agonist-treatment were detected. ERα protein levels displayed no sex differences at basal level. After E2-treatment ERα protein was up-regulated in male cells, but decreased in cardiac fibroblasts from females. ERβ protein was higher in female cells compared to males, but the expression was not regulated by E2 in both sexes.
Sex-specific regulation of collagen I and III expression by E2 in cardiac fibroblasts might be responsible for sex-differences in cardiac fibrosis. This might be due to sexually dimorphic ER expression and regulation. Understanding how E2 and ER mediate sex-differences in cardiac remodeling may help to design sex-specific pharmacological interventions.

Abstract
Clinical findings show sex differences in the manifestation of a number of cardiovascular diseases (CVD). However, the underlying molecular mechanisms are incompletely understood. Multiple animal models suggest sex differences in the manifestation of CVD, and provide strong experimental evidence that different major pathways are regulated in a sex-specific manner. In most animal studies females display a lower mortality, less severe hypertrophy, and better preserved cardiac function compared with male counterparts. The data support the hypothesis that female sex and/or the sex hormone estrogen (17β-estradiol; E2) may contribute to the sexual dimorphism in the heart and to a better outcome of cardiac diseases in females. To improve our understanding of the sex-based molecular and cellular mechanisms of CVD and to develop new therapeutic strategies, the use of appropriate animal models is essential. This review highlights recent findings from animal models relevant for studying the mechanisms of sexual dimorphisms in the healthy and diseased heart, focusing on physiological hypertrophy (exercise), pathological hypertrophy (volume and pressure overload induced hypertrophy), and heart failure (myocardial infarction). Furthermore, the potential effects of E2 in these models will be discussed.

Abstract
We and others found sex differences in physiological myocardial hypertrophy (MH) in mice subjected to voluntary cage-wheel running (VCR) and forced exercise training. Female mice showed significantly more MH, suggesting the involvement of estrogen (E2) and estrogen receptors (ER). We therefore investigated the underlying mechanisms leading to sex differences in physiological MH and the role of E2 and ER beta (ERß). Male and female C57/Bl6 wild-type (WT) and ERß-deficient mice (ERß-/-) at the age of 12 weeks performed 8 weeks of VCR or were kept sedentary (sed). Exercise performance was monitored daily and left ventricular mass (LVM) was examined by echocardiography. RNA and protein were analyzed by Real-Time PCR and western blot. Luciferase-reporter Assays were performed with PGC-1a-, MEF2A- and MEF2C-promoter deletion constructs in a human cardiac myocyte cell line (AC16 cells) with/without E2 treatment. Female WT-mice run more than their male counterparts (6.7km/day vs. 4.2km/day; p<0.001). Females showed significant greater increase in LVM and cardiomyocyte diameter in response to exercise compared to males. VCR led to a significant activation of AKT and p38-MAPK signalling in female running-mice, but not in males. Mitochondrial biogenesis associated genes MEF2A and ATP5K mRNA expression were significantly higher in female VCR mice. Female and male ERß-/- mice showed similar running performance compared with WT-mice (6.3km/day vs. 2.7km/day; respectively; p<0.001); however they showed no changes in LVM compared to sed-controls. In contrast to WT animals, female ERß-/- mice showed no increase in AKT and p38-MAPK phosphorylation or up-regulation of mitochondrial key enzymes. E2-treatment of AC16 cells up-regulated mitochondrial target genes (PGC-1a, MEF2A NRF1/2 and TFAM) and led to nuclear translocation of PGC-1a. E2 increased transcriptional activity of PGC-1a and MEF2A/C in an ER dependent manner in cardiomyocytes. Female hearts develop more physiological MH due to exercise, characterized by a stronger activation of pathways and genes involved in the regulation of mitochondrial function. ERß is necessary for the development of physiological hypertrophy and for the activation of p38- MAPK and AKT pathways in female mice.

Abstract
Background—
In patients with aortic stenosis, pressure overload induces cardiac hypertrophy and fibrosis. Female sex and estrogens influence cardiac remodeling and fibrosis in animal models and in men. Sex differences and their molecular mechanisms in hypertrophy regression after aortic valve replacement have not yet been studied.
Methods and Results—
We prospectively obtained preoperative and early postoperative echocardiography in 92 patients, 53 women and 39 men, undergoing aortic valve replacement for isolated aortic stenosis. We analyzed in a subgroup of 10 patients matrix gene expression in left ventricular (LV) biopsies. In addition, we determined the effect of 17β-estradiol on collagen synthesis in isolated rat cardiac fibroblasts. Preoperatively, women and men had similar ejection fraction. Similar percentages of women and men had increased LV diameters (37% and 38%). Women more frequently exhibited LV hypertrophy than men (women: 86%; men: 56%;
P
<0.01). Postoperatively, increased LV diameters persisted in 34% of men but only in 12% of women (
P
<0.023). LV hypertrophy reversed more frequently in women than in men, leading to a similar prevalence of LV hypertrophy after surgery (women: 45%; men: 36%). In surgical biopsies, men had significantly higher collagen I and III and matrix metalloproteinase 2 gene expression than women. In isolated rat cardiac fibroblasts, 17β-estradiol significantly increased collagen I and III gene expressions in male cells but decreased it in female cells.
Conclusion—
Women adapt to pressure overload differently from men. Less fibrosis before surgery may enable faster regression after surgery.

Abstract
We investigated sex differences and the role of estrogen receptor-beta (ERbeta) on myocardial hypertrophy in a mouse model of pressure overload. We performed transverse aortic constriction (TAC) or sham surgery in male and female wild-type (WT) and ERbeta knockout (ERbeta(-/-)) mice. All mice were characterized by echocardiography and hemodynamic measurements and were killed 9 wk after surgery. Left ventricular (LV) samples were analyzed by microarray profiling, real-time RT-PCR, and histology. After 9 wk, WT males showed more hypertrophy and heart failure signs than WT females. Notably, WT females developed a concentric form of hypertrophy, while males developed eccentric hypertrophy. ERbeta deletion augmented the TAC-induced increase in cardiomyocyte diameter in both sexes. Gene expression profiling revealed that WT male hearts had a stronger induction of matrix-related genes and a stronger repression of mitochondrial genes than WT female hearts. ERbeta(-/-) mice exhibited a different transcriptional response. ERbeta(-/-)/TAC mice of both sexes exhibited induction of proapoptotic genes with a stronger expression in ERbeta(-/-) males. Cardiac fibrosis was more pronounced in male WT/TAC than in female mice. This difference was abolished in ERbeta(-/-) mice. The number of apoptotic nuclei was increased in both sexes of ERbeta(-/-)/TAC mice, most prominent in males. Female sex offers protection against ventricular chamber dilation in the TAC model. Both female sex and ERbeta attenuate the development of fibrosis and apoptosis, thus slowing the progression to heart failure.

Abstract
AIMS Female sex and sex hormones contribute to cardiac remodelling. 17beta-estradiol (E2) is involved in the modulation of extracellular matrix composition and function. Here, we analysed the effect of E2 on matrix metalloproteinase (MMP)-2 gene expression and studied the underlying molecular mechanisms in rat cardiac fibroblasts and in a human fibroblast cell line. METHODS AND RESULTS In adult rat cardiac fibroblasts, E2 significantly decreased MMP-2 gene expression in an estrogen receptor (ER)-dependent manner. Transient transfection experiments of human MMP-2 (hMMP-2) promoter deletion constructs in a human fibroblast cell line revealed a regulatory region between -324 and -260 bp that is involved in E2/ERalpha-mediated repression of hMMP-2 gene transcription. Electrophoretic mobility shift assays (EMSA) and supershift analysis demonstrated the binding of transcription factor Elk-1 within this promoter region. Elk-1 was phosphorylated by E2 via the mitogen-activated protein kinase (MAPK) signalling pathway as shown by western blotting. Treatment of cells with the MAPK inhibitor PD98059 blocked the E2-dependent repression of hMMP-2 promoter activity as well as the endogenous MMP-2 mRNA levels in both human fibroblast cells and rat cardiac fibroblasts. CONCLUSION E2 inhibits MMP-2 expression via the ER and the MAPK pathway in rat cardiac fibroblasts and in a human fibroblast cell line. These mechanisms may contribute to sex-specific differences in fibrotic processes that are observed in human heart and other diseases.

Abstract
Estrogen receptor (ER)-mediated effects have been associated with the modulation of myocardial hypertrophy in animal models and in humans, but the regulation of ER expression in the human heart has not yet been analyzed. In various cell lines and tissues, multiple human estrogen receptor alpha (hERalpha) mRNA isoforms are transcribed from distinct promoters and differ in their 5'-untranslated regions. Using PCR-based strategies, we show that in the human heart the ERalpha mRNA is transcribed from multiple promoters, namely, A, B, C, and F, of which the F-promoter is most frequently used variant. Transient transfection reporter assays in a human cardiac myocyte cell line (AC16) with F-promoter deletion constructs demonstrated a negative regulatory region within this promoter. Site-directed mutagenesis and electrophoretic mobility shift assays indicated that NF-kappaB binds to this region. An inhibition of NF-kappaB activity by parthenolide significantly increased the transcriptional activity of the F-promoter. Increasing NF-kappaB expression by tumor necrosis factor-alpha reduced the expression of ERalpha, indicating that the NF-kappaB pathway inhibits expression of ERalpha in human cardiomyocytes. Finally, 17beta-estradiol induced the transcriptional activity of hERalpha promoters A, B, C, and F. In conclusion, inflammatory stimuli suppress hERalpha expression via activation and subsequent binding of NF-kappaB to the ERalpha F-promoter, and 17beta-estradiol/hERalpha may antagonize the inhibitory effect of NF-kappaB. This suggests interplay between estrogen/estrogen receptors and the pro-hypertrophic and inflammatory responses to NF-kappaB.
