Lockwood C, Vo AS, Bellafard H, Carter AJR. More evidence for widespread antagonistic pleiotropy in polymorphic disease alleles. Front Genet 2024; 15:1404516.

Abstract
Introduction Many loci segregate alleles classified as "genetic diseases" due to their deleterious effects on health. However, some disease alleles have been reported to show beneficial effects under certain conditions or in certain populations. The beneficial effects of these antagonistically pleiotropic alleles may explain their continued prevalence, but the degree to which antagonistic pleiotropy is common or rare is unresolved. We surveyed the medical literature to identify examples of antagonistic pleiotropy to help determine whether antagonistic pleiotropy appears to be rare or common. Results We identified ten examples of loci with polymorphisms for which the presence of antagonistic pleiotropy is well supported by detailed genetic or epidemiological information in humans. One additional locus was identified for which the supporting evidence comes from animal studies. These examples complement over 20 others reported in other reviews. Discussion The existence of more than 30 identified antagonistically pleiotropic human disease alleles suggests that this phenomenon may be widespread. This poses important implications for both our understanding of human evolutionary genetics and our approaches to clinical treatment and disease prevention, especially therapies based on genetic modification.

Abstract
Objective Polycystic ovary syndrome (PCOS) is a common multifactorial endocrine disorder affecting women of reproductive age. ACE enzyme is involved in the physiopathology of the ovarian system, and there are inconsistencies between studies regarding the association between ACE gene variants and PCOS. The objective of this study is to evaluate the association between ACE I/D gene polymorphisms and PCOS, as well as its clinical manifestations, in Iranian women with PCOS. Design This study included 140 patients with PCOS and 153 controls without the disease. Samples were collected from Yas Hospital Complex in Tehran-Iran during 2018 to 2022. Genomic DNA was obtained from whole blood samples using salt extraction, and genotyping was carried out using polymerase chain reaction (PCR). Results Variants of DD, ID, and II were observed in 31.4, 44.3, and 24.3% of PCOS, and 38.6, 44.1, and 17.2% of control group, respectively. The frequency of ACE gene variants did not differ between PCOS patients and control group. A significant difference was observed between the frequency of elevated LH to FSH ratio > 2 and ACE gene polymorphisms in patients with PCOS (OR: 0.32 (0.12-0.88), P value 0.024) with lower frequency observed in D allele carriers. Conclusion This study indicate that although ACE I/D variants frequency in PCOS women is similar to non-PCOS women, it may be involved in the pathogenesis of the disease through mechanisms regulating steroidogenesis in the ovary and suggests that ACE might be related to exacerbated clinical manifestations of PCOS which requires further investigations.

Testosterone-associated blood pressure dysregulation in women with androgen excess polycystic ovary syndrome. Am J Physiol Heart Circ Physiol 2023; 325:H232-H243. [PMID: 37327000 PMCID: PMC10393337 DOI: 10.1152/ajpheart.00164.2023] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/20/2023] [Revised: 06/12/2023] [Accepted: 06/12/2023] [Indexed: 06/17/2023]
Abstract
We tested the hypothesis that hyperandrogenemia in androgen excess polycystic ovary syndrome (AE-PCOS) is a primary driver in blood pressure (BP) dysregulation via altered sympathetic nervous system activity (SNSA), reduced integrated baroreflex gain and increased renin-angiotensin system (RAS) activation. We measured resting SNSA (microneurography), integrated baroreflex gain, and RAS with lower body negative pressure in obese insulin-resistant (IR) women with AE-PCOS [n = 8, 23 ± 4 yr; body mass index (BMI) = 36.3 ± 6.4 kg/m2] and obese IR controls (n = 7, control, 29 ± 7 yr; BMI = 34.9 ± 6.8 kg/m2), at baseline (BSL), after 4 days of gonadotropin-releasing hormone antagonist (ANT, 250 μg/day) and 4 days of ANT + testosterone (ANT + T, 5 mg/day) administration. Resting BP was similar between groups for systolic blood pressure (SBP; 137 ± 14 vs. 135 ± 14 mmHg, AE-PCOS, control) and diastolic BP (89 ± 21 vs. 76 ± 10 mmHg, AE-PCOS, control). BSL integrated baroreflex gain was similar between groups [1.4 ± 0.9 vs. 1.0 ± 1.3 forearm vascular resistance (FVR) U/mmHg], but AE-PCOS had lower SNSA (10.3 ± 2.0 vs. 14.4 ± 4.4 burst/100 heartbeats, P = 0.04). In AE-PCOS, T suppression increased integrated baroreflex gain, which was restored to BSL with ANT + T (4.3 ± 6.5 vs. 1.5 ± 0.8 FVR U/mmHg, ANT, and ANT + T, P = 0.04), with no effect in control. ANT increased SNSA in AE-PCOS (11.2 ± 2.4, P = 0.04). Serum aldosterone was greater in AE-PCOS versus control (136.5 ± 60.2 vs. 75.7 ± 41.4 pg/mL, AE-PCOS, control, P = 0.04) at BSL but was unaffected by intervention. Serum angiotensin-converting enzyme was greater in AE-PCOS versus control (101.9 ± 93.4 vs. 38.2 ± 14.7 pg/mL, P = 0.04) and reduced by ANT in AE-PCOS (77.7 ± 76.5 vs. 43.4 ± 27.3 µg/L, ANT, and ANT + T, P = 0.04) with no impact on control. Obese, IR women with AE-PCOS showed decreased integrated baroreflex gain and increased RAS activation compared with control.NEW & NOTEWORTHY Here we present evidence for an important role of testosterone in baroreflex control of blood pressure and renal responses to baroreceptor unloading in women with a common, high-risk androgen excess polycystic ovary syndrome (AE-PCOS) phenotype. These data indicate a direct effect of testosterone on the vascular system of women with AE-PCOS independent of body mass index (BMI) and insulin-resistant (IR). Our study indicates that hyperandrogenemia is a central underlining mechanism of heightened cardiovascular risk in women with PCOS.

Abstract
Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women of reproductive age, affecting approximately 10%. PCOS is diagnosed by the presence of at least two of these three criteria: hyperandrogenemia, oligo- or anovulation, and polycystic ovaries. The most common type (80%) of PCOS includes hyperandrogenemia. PCOS is also characterized by obesity or overweight (in 80% of US women with PCOS), insulin resistance with elevated plasma insulin but not necessarily hyperglycemia, dyslipidemia, proteinuria, and elevated BP. Although elevated compared with age-matched controls, BP may not reach levels considered treatable according to the current clinical hypertension guidelines. However, it is well known that elevated BP, even modestly so, increases the risk of cardiovascular disease. We have developed a model of hyperandrogenemia in rodents that mimics the characteristics of PCOS in women, with increases in body weight, insulin resistance, dyslipidemia, andproteinuria and elevated BP. This review discusses potential mechanisms responsible for the elevated BP in the adult and aging PCOS rat model that may be extrapolated to women with PCOS.

Abstract
Our modern era is witnessing an increasing infertility rate worldwide. Although some of the causes can be attributed to our modern lifestyle (e.g., persistent organic pollutants, late pregnancy), our knowledge of the human ovarian tissue has remained limited and insufficient to reverse the infertility statistics. Indeed, all efforts have been focused on the endocrine and cellular function in support of the cell theory that dates back to the 18th century, while the human ovarian matrisome is still under-described. Hereby, we unveil the extracellular side of the story during different periods of the ovary life, demonstrating that follicle survival and development, and ultimately fertility, would not be possible without its involvement. We examined the human ovarian matrisome and described its remodeling from prepuberty until menopause, creating the first ovarian proteomic codex. Here, we confidently identified and quantified 98 matrisome proteins present in the three ovary groups. Among them, 26 were expressed differently among age groups, delineating a peculiar matrisomal fingerprint at each stage. Such proteins could be potential biomarkers phenotyping ovarian ECM at each age phase of female reproductive life. Beyond proteomics, our study presents a unique approach to understanding the data and depicting the spatiotemporal ECM-intracellular signaling networks and remodeling with age through imaging, advanced text-mining based on natural language processing technology, machine learning, and data sonification. Our findings provide essential context for healthy ovarian physiology, identifying and characterizing disease states, and recapitulating physiological tissues or development in vitro. This comprehensive proteomics analysis represents the ovarian proteomic codex and contributes to an improved understanding of the critical roles that ECM plays throughout the ovarian life span.

Abstract
The local Renin-Angiotensin System (RAS) has been demonstrated to exist in a wide range of tissues and organs, In the female reproductive system, it is mainly found in the ovary, uterus and placenta. The RAS system is made up of a series of active substances and enzymes, in addition to the circulating endocrine renin-angiotensin system. The active peptides Angiotensin II (Ang II) and Angiotensin (1-7) (Ang-(1-7)), in particular, appear to have distinct activities in the local RAS system, which also controls blood pressure and electrolytes. Therefore, in addition to these features, angiotensin and its receptors in the reproductive system seemingly get involved in reproductive processes, such as follicle growth and development, as well as physiological functions of the placenta and uterus. In addition, changes in local RAS components may induce reproductive diseases as well as pathological states such as cancer. In most tissues, Ang II and Ang- (1-7) seem to maintain antagonistic effects, but this conclusion is not always true in the reproductive system, where they play similar functions in some physiological and pathological roles. This review investigated how Ang II, Ang- (1-7) and their receptors were expressed, localized, and active in the female reproductive system. This review also summarized their effects on follicle development, uterine and placental physiological functions. The changes of local RAS components in a series of reproductive system diseases including infertility related diseases and cancer and their influence on the occurrence and development of diseases were elucidated. This article reviews the physiological and pathological roles of Ang II and Ang- (1-7) in female reproductive system,a very intricate system of tissue factors that operate as agonists and antagonists was found. Besides, the development of novel therapeutic strategies targeting components of this system may be a research direction in future.

Abstract
Rec ent studies have suggested a closer association between angiotensin-converting enzyme (ACE) gene polymorphisms and polycystic ovary syndrome (PCOS) risk, but the results were inconsistent. We conducted this meta-analysis to explore the precise associations between ACE gene I/D polymorphism and PCOS risk. Online electronic databases (PubMed, Embase, SCI index, CNKI, and Wanfang) were searched. Odds ratios (ORs) with 95% confidence interval (CIs) were calculated to assess the association between ACE gene I/D polymorphism and PCOS risk. In addition, heterogeneity, accumulative/sensitivity analysis, and publication bias were conducted to check the statistical power. Overall, 12 published case-control studies with 2248 patients and 1759 controls were included according to the criteria. Significant increased risk was found for PCOS susceptibility with I/D mutation (D vs. I: OR = 1.62, 95%CI = 1.24-2.11, P < 0.01, I2 = 86.1%; DD vs. II: OR = 2.10, 95%CI = 1.35-3.27, P < 0.01, I2 = 79.8%; ID + DD vs. II: OR = 1.57, 95%CI = 1.06-2.32, P = 0.02, I2 = 79.3%; DD vs. II + ID: OR = 1.91, 95%CI = 1.39-2.65, P < 0.01, I2 = 79.1%). Furthermore, some similar associations were also observed in subgroups. In summary, the current evidences indicated that ACE gene I/D polymorphism plays an important role in PCOS development, both in Asian and Caucasian descendants.

Abstract
BACKGROUND Androgenetic alopecia (AGA) is a prevalent condition with a complex etiopathogenesis. Angiotensin-converting enzyme (ACE) gene located on the chromosome 17q23 contains an insertion (I) and deletion (D) polymorphism in the intron 16. This gene polymorphism plays a role in multiple inflammatory disorders. However, there are no studies investigating its association with AGA susceptibility. OBJECTIVES In this work, we aimed at exploring the association of ACE gene I/D polymorphism in AGA susceptibility in a group of Egyptian patients. METHODS This study included 100 AGA patients, and 100 apparently healthy controls. The ACE gene I/D polymorphism was analyzed by polymerase chain reaction. RESULTS The DD, ID genotypes, and D allele showed higher frequent distribution among studied AGA patients than controls (p < 0.05 each). Positive family history and ACE gene I/D polymorphism were considered AGA susceptibility predictors in both uni- and multivariable analyses [p < 0.05 each (OR (95% CI)] on applying logistic regression analysis for risk factors prediction. CONCLUSIONS This study highlights the possible contribution of the suspected genetic polymorphism as a susceptibility indicator for AGA development in the examined group of patients.

Abstract
There is controversy about the relationship between ACE I/D polymorphism and health. Seventy-four healthy adults (n = 28 women; 22.5 ± 4.2 years) participated in this cross-sectional study aimed at determining the influence of ACE I/D polymorphism, ascertained by polymerase chain reaction, on cardiometabolic risk (i.e., waist circumference, body fat, blood pressure (BP), glucose, triglycerides, and inflammatory markers), maximal fat oxidation (MFO), cardiorespiratory fitness (maximal oxygen uptake), physical activity and diet. Our results showed differences by ACE I/D polymorphism in systolic BP (DD: 116.4 ± 11.8 mmHg; ID: 116.7 ± 6.3 mmHg; II: 109.4 ± 12.3 mmHg, p = 0.035) and body fat (DD: 27.3 ± 10.8%; ID: 22.6 ± 9.7%; II: 19.3 ± 7.1%, p = 0.030). Interestingly, a genotype*sex interaction in relativized MFO by lean mass (p = 0.048) was found. The DD polymorphism had higher MFO values than ID/II polymorphisms in men (8.4 ± 3.0 vs. 6.5 ± 2.9 mg/kg/min), while the ID/II polymorphisms showed higher R-MFO values than DD polymorphism in women (6.6 ± 2.3 vs. 7.6 ± 2.6 mg/kg/min). In conclusion, ACE I/D polymorphism is apparently associated with adiposity and BP, where a protective effect can be attributed to the II genotype, but not with cardiorespiratory fitness, diet and physical activity. Moreover, our study highlighted that there is a sexual dimorphism in the influence of ACE I/D gene polymorphism on MFO.

Abstract
Polycystic ovary syndrome, the most common endocrine disorder in women of reproductive age, is characterized by hyperandrogenemia, obesity, insulin resistance, and elevated blood pressure. However, few studies have focused on the consequences of pregnancy on postmenopausal cardiovascular disease and hypertension in polycystic ovary syndrome women. In hyperandrogenemic female (HAF) rats, the hypothesis was tested that previous pregnancy protects against age-related hypertension. Rats were implanted with dihydrotestosterone (7.5 mg/90 days, beginning at 4 weeks and continued throughout life) or placebo pellets (controls), became pregnant at 10 to 15 weeks, and pups were weaned at postnatal day 21. Dams and virgins were then aged to 10 months (still estrous cycling) or 16 months (postcycling). Although numbers of offspring per litter were similar for HAF and control dams, birth weights were lower in HAF offspring. At 10 months of age, there were no differences in blood pressure, proteinuria, nitrate/nitrite excretion, or body composition in previously pregnant HAF versus virgin HAF. However, by 16 months of age, despite no differences in dihydrotestosterone, fat mass/or lean mass/body weight, previously pregnant HAF had significantly lower blood pressure and proteinuria, higher nitrate/nitrite excretion, with increased intrarenal mRNA expression of endothelin B receptor and eNOS (endothelial nitric oxide synthase), and decreased ACE (angiotensin-converting enzyme), AT1aR (angiotensin 1a receptor), and endothelin A receptor than virgin HAF. Thus, pregnancy protects HAF rats against age-related hypertension, and the mechanism(s) may be due to differential regulation of the nitric oxide, endothelin, and renin-angiotensin systems. These data suggest that polycystic ovary syndrome women who have experienced uncomplicated pregnancy may be protected from postmenopausal hypertension.

Abstract
This study was designed to investigate the relationship between the levels of select adipocytokines (adiponectin, visfatin and apelin) and angiotensin in converting enzyme (ACE) gene insertion/deletion (ID) polymorphism in lean women with and without polycystic ovary syndrome (PCOS). The PCOS group (N = 94) was identified according to the Rotterdam criteria. The Control group (N = 68) included age- and body mass index (BMI)-matched healthy volunteers. Serum levels of adipocytokines were measured using enzyme immunoassays (EIA) and ACE genes were evaluated by polymerase chain reaction (PCR). The PCOS group, when compared to the Control group had lower adiponectin (p < .001) but higher visfatin (p < .001) and apelin (p = .003). There was no significant correlation of the levels of these adipocytokines with BMI, fasting glucose, fasting insulin or Homeostasis Model Assessment-Insulin Resistance (HOMA-IR). The PCOS and the Control groups also differed with regard to the ACE ID genotype distribution (p < .001). The ID, DD, and II genotype frequencies were, respectively, 34, 57 and 9% in the PCOS group and 49, 22 and 29% in the Control group. When stratified according to individual ID genotypes, the levels of adipocytokines in the PCOS and the Control groups remained significantly different. There was no statistically significant relationship between the levels of adipocytokines and ACE ID genotypes.

Abstract
This investigation was conducted to evaluate comparison of myo-inositol and metformin on glycemic control, lipid profiles, and gene expression related to insulin and lipid metabolism in women with polycystic ovary syndrome (PCOS). This randomized controlled trial was conducted on 53 women with PCOS, aged 18-40 years old. Subjects were randomly allocated into two groups to take either myo-inositol (n = 26) or metformin (n = 27) for 12 weeks. Myo-inositol supplementation, compared with metformin, significantly reduced fasting plasma glucose (FPG) (β -5.12 mg/dL; 95% CI, -8.09, -2.16; p=.001), serum insulin levels (β -1.49 µIU/mL; 95% CI, -2.28, -0.70; p<.001), homeostasis model of assessment-insulin resistance (β -0.36; 95% CI, -0.55, -0.17; p<.001), serum triglycerides (β 12.42 mg/dL; 95% CI, -20.47, -4.37; p=.003) and VLDL-cholesterol levels (β -2.48 mg/dL; 95% CI, -4.09, -0.87; p=.003), and significantly increased the quantitative insulin sensitivity check index (β 0.006; 95% CI, 0.002, 0.01; p=.006) compared with metformin. Moreover, myo-inositol supplementation upregulated gene expression of peroxisome proliferator-activated receptor gamma (PPAR-γ) (p=.002) compared with metformin. Overall, taking myo-inositol, compared with metformin, for 12 weeks by women with PCOS had beneficial effects on glycemic control, triglycerides and VLDL-cholesterol levels, and gene expression of PPAR-γ.

Abstract
PURPOSE To investigate the contribution of the deletion polymorphism and insertion (rs1799752) of the angiotensin converting enzyme (ACE) gene in the aetiology of Polycystic Ovarian Syndrome (PCOS). METHODOLOGY 97 women diagnosed with PCOS who received care at the Gynaecology and Obstetrics clinic of the Hospital das Clínicas of UFTM, participated in this study. The control group consisted of 94 women. All participants were submitted to the collection of 10 mL of whole blood and the genomic DNA was obtained by the saline extraction method. The genotyping of the samples was performed by means of the Polymerase Chain Reaction (PCR). The statistics analyses were performed by descriptive analysis, univariate analysis and logistic regression model. The results were presented in odds ratio (OR) and confidence interval of 95% (CI-95%), with a significance level of 5% (p≤0.05). RESULTS There were no statistical differences between patients and controls for the genotypic (χ2 = 1.52, p = 0.47) and allelic frequencies (χ2 = 0.21, p = 0.76). The distribution of the genotypic frequency is not in HWE for patients (χ2 = 18.80, p <0.05) and for controls (χ2 = 6.85, p <0.05). In relation to the risk factors for the syndrome, the history of familial PCOS is more frequent between women with the syndrome. CONCLUSION In the study population, there was no association between I/D polymorphism of the ACE gene and PCOS.

Abstract
OBJECTIVE To our knowledge, data on comparison of myo-inositol and metformin on clinical, metabolic and genetic parameters in subjects with polycystic ovary syndrome (PCOS) are limited. This study was carried out to compare myo-inositol and metformin on clinical, metabolic and genetic parameters in subjects with PCOS. DESIGN, PATIENTS AND MEASUREMENTS This randomized controlled trial was conducted among 60 subjects with PCOS aged 18-40 years. Subjects were randomly allocated into two groups to receive either myo-inositol (N=30) or metformin (N=30) for 12 weeks. Gene expression of inflammatory cytokines was assessed in peripheral blood mononuclear cells (PBMCs) of PCOS women by RT-PCR. RESULTS After the 12-week intervention, compared with metformin, myo-inositol intake significantly decreased serum total testosterone (-1.4±4.2 vs +0.7±1.4 nmol/L, P=.03), modified Ferriman-Gallwey (mF-G) scores (-1.1±0.7 vs -0.5±0.8, P=.01) and serum high-sensitivity C-reactive protein (hs-CRP) levels (-2.6±3.9 vs +0.2±1.5 mg/L, P<.001). RT-PCR demonstrated that compared with metformin, myo-inositol downregulated gene expression of interleukin-1 (IL-1) (P=.02) in PBMCs of subjects with PCOS. We did not observe any significant effect of myo-inositol intake compared with metformin on other hormonal profiles, plasma nitric oxide (NO) or gene expression of IL-8 and tumour necrosis factor alpha (TNF-α). CONCLUSIONS Overall, taking myo-inositol, compared with metformin, for 12 weeks in patients with PCOS with hyperinsulinism and normoinsulinism had beneficial effects on total testosterone, mFG scores, serum hs-CRP levels and gene expression of IL-1, but did not affect other hormonal profiles, NO levels or gene expression of IL-8 and TNF-α.
