Jingyun Z, Zhaoyan N, Xianglong K, Liqian, Na Z, Lvcuiting, Lina G, Haifeng W. Study on the relationship between SlRTl and oxidative stress in aged patients undergoing in vitro fertilization and embryo transfer cycles. J Gynecol Obstet Hum Reprod 2023; 52:102516. [PMID: 36442811 DOI: 10.1016/j.jogoh.2022.102516] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2022] [Revised: 11/24/2022] [Accepted: 11/25/2022] [Indexed: 11/27/2022]
Abstract
PURPOSE Oxidative stress (OS) has been suggested to be involved in the pathogenesis of fertility reduction in aged patient. Silent Information Regulator 1 (SIRT1) is involved in antioxidant defense and also plays a role in regulation ovarian function. The purpose of this study was to evaluate SIRT1 and OS markers in follicular fluid (FF) and granulosa cells (GCs) for aged patient undergoing in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI). METHODS This single-center prospective cohort study was performed from May 2020 to October 2021, including 92 patients undergoing IVF/ICSI at authors' institute. The patients were grouped by age, including group A (< 35 year, n = 28, age range 24-29), group B (35-40 year, n = 33, age range 35-40), and group C (> 40 year, n = 31, age range 41-47). The outcomes included in vitro fertilization and embryo transfer (IVF-ET) results, OS markers and SIRT1 levels. RESULTS Women in group B and group C had a significantly lower estradiol (E2) in the trigger day, retrieved oocytes, mature oocytes, two pronuclei (2PN) and Day3 available embryos than group A. Women in group C had a significantly lower implantation rate and clinical pregnancy rate than group A. The superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities and SIRT1 levels were lower in FF of the group B and group C, whereas the malondialdehyde (MDA) level was higher than that in the group A. Moreover, the MDA levels were correlated negatively with SIRT1 (r = -0.422, P=0.001),while the SOD and GSH-Px was positively correlated with SIRT1 (r = 0.409, P = 0.001 and r = 0.526, P = 0.001). CONCLUSIONS The oxidative stress may be related to the decrease of SIRT1 in aged patients undergoing IVF-ET.

Abstract
BACKGROUND The anti-Müllerian-hormone (AMH) is secreted by the granulosa cells of the oocytes and can be used as a marker of the ovarian reserve; helpful to estimate female fertility or the menopause onset. Although various factors may influence AMH levels, the correlation with nutritional factors needs more research. OBJECTIVE To evaluate the effect of a micronutrient supplementation on female AMH levels. METHODS This retrospective analysis includes a total of 244 women, who attended the Karl Landsteiner Institute, Korneuburg, Austria from January 2013 to June 2019 due to an unfulfilled desire for a child. All women were treated with an oral micronutrient preparation consisting the dosage of one soft capsule and one tablet per day for 3 months. The soft capsule contains omega-3 fatty acids and the tablet is a standardized combination of coenzyme Q10, vitamin E, folic acid, selenium, catechins from green tea extract, and glycyrrhizin from licorice extract. Serum AMH levels before and after 3 months were compared. In addition, available clinical data such as ovulation frequency, endometrium thickness, and luteal phase duration were analyzed. RESULTS The mean age of the women was 37.3 ± 1.8 years, the mean body mass index of 24.3 ± 4.6 k/m2. The mean serum AMH levels and endometrial thickness values were significantly higher after micronutrient supplementation as compared to baseline (1.42 ± 0.86 versus 1.86 ± 0.82 ng/mL and 6.10 ± 1.76 versus 7.29 ± 1.65 mm, respectively). In addition, ovulation frequency and luteal phase duration significantly improved in more than 60%. CONCLUSION Proposed micronutrient supplementation had a positive effect on serum AMH levels, endometrial thickness, ovulation frequency, and luteal phase duration. It could be a simple, risk-free therapeutic option to improve female fertility. More research is warranted to prove this effect.

Abstract
This article proposes going back in the history of reproductive medicine to shed light on the role of assisted reproductive technology (ART) in the making of 'old eggs'. Focusing on two key technologies - egg donation and cytoplasmic transfer - both of which contributed significantly to the production of scientific knowledge about reproductive ageing, the article suggests that ART can be analysed as 'in-vivo models' playing a pivotal role in the shift from age as a demographic variable to ageing understood in biological terms. It will shed light on the role of ART in locating age in the eggs and producing a cellular understanding of fertility decline. It argues that ART not only offers new means of reconfiguring the biological clock by extending fertility, but also reconfigures the biology of reproductive ageing itself. This becomes both the target and the means for new technological interventions, imaginaries and norms, anchored in women's bodies and a more plastic biology, and thereby illuminates hitherto underexplored aspects of the encounter between the science and technology of reproduction and anti-ageing.

Abstract
OBJECTIVES To investigate whether growth hormone (GH) can improve oxidative stress (OS) by affecting) /nuclear factor erythroid 2-related factor 2 (Nrf2)/Kelch-like ECH-associated protein 1 (Keap1) in women of advanced age undergoing in vitro fertilization (IVF). METHODS This retrospective study enrolled 141 patients, including 65 aged C patients (patients not treated with GH) and 76 aged GH patients (patients treated with GH). The outcomes included IVF-ET results, OS markers in follicle fluid (FF) and Nrf2 and Keap1 mRNA and protein expressions in granulosa cells (GCs). RESULTS The results showed that GH improved the available blastocyst (p=.047) and implantation rate (p=.043) in women of advanced age undergoing IVF. The malondialdehyde (MDA) content of FF was significantly higher in the aged-C group than in the aged-GH group (p=.013). The antioxidant enzyme activities of superoxide dismutase (SOD), glutathione peroxidase (GSH-px) and catalase (CAT) were significantly lower in the aged-C group than in the aged-GH group (p= .000, p= .049, p= .012 respectively). Nrf2 mRNA and protein expression was significantly higher and Keap1 mRNA and protein expression was lower in the aged-GH group than in the aged-C group (p= .000, p= .000 respectively). CONCLUSIONS The study showed that GH improved embryo quality and implantation rate and alleviated OS in FF, which may be related to Nrf2/Keap1.

Abstract
Abstract
Background
Clomiphene Citrate is considered the gold-standard for induction of ovulation and has been used for several years to treat PCOS related infertility. Unfortunately, 15-40% of women with PCOS are resistant to Clomiphene Citrate. The study aimed to evaluate potential benefits of adding the active form of Coenzyme Q10 (Ubiquinol) to Clomiphene Citrate compared with Human Menopausal Gonadotropins (hMG) in Clomiphene Citrate resistant PCOS patients. 148 PCOS Patients with Clomiphene Citrate resistance were randomized into two groups (A and B). In group A, controlled ovarian stimulation was done by Clomiphene Citrate 150 mg daily (from 2nd till 6th day of cycle) together with Ubiquinol starting from 2nd day till day of hCG triggering in a dose of 100 mg orally once daily. In group B, hMG was given from 2nd day of the cycle in a dose ranging from 75 to 225 IU. Serial transvaginal ultrasonography was done starting on cycle day 8 and continued till size of leading follicle reaches 18 mm or more then ovulation triggering was done. Thereafter, patients were advised for a timed intercourse (TI) after 36 hours. A blood sample was withdrawn seven days after hCG triggering, for measurement of serum progesterone. If the Patient presented with a missed period for one week, a serum sample was sent for β-hCG.
Results
There were no statistically significant differences (P > 0.05) between studied groups regarding; number of cases reaching mature follicular size, number of stimulated cycles, endometrial thickness on the day of hCG triggering, mid-luteal serum progesterone, positive serum pregnancy test and clinical pregnancy rate.
Conclusions
Addition of Ubiquinol to Clomiphene Citrate improved ovarian responsiveness in Clomiphene Citrate resistant patients with results comparable to conventional hMG stimulation protocol.

Abstract
Although ovarian aging is a key cause of decreased ovarian function and oocyte quality, it remains a problem in infertility treatment. Therefore, this study is aimed to investigate whether Paeonia lactiflora (PL), a herb improves ovarian function and oocyte quality using aged female mice. C57BL/6 female mice aged 8 months were treated orally every day with PL of 26.5 mg/kg (n=7) and 53 mg/kg (n=7) of body weight for 4 weeks using an oral zoned needle. The control group (n=7) was treated with normal saline. Ovaries and serum were collected for the H&E stain and the evaluation of reactive oxygen species (ROS) levels, respectively. In the second experiment, female mice were orally administered with PL (26.5 mg/kg: n=12, 53 mg/kg: n=12, control: n=12) and then superovulated with PMSG and hCG, and mated with male mice. Zygotes were retrieved and cultured for 4 days. Ovaries were provided for examination of expressions of genes associated with angiogenesis (VEGF and visfatin), anti-aging (Sirt1 and Sirt2), and follicular development (c-Kit, BMP-15, and GDF-9). PL significantly increased numbers of surviving follicles (primordial, primary, secondary, and antral), numbers of zygotes retrieved, embryo development rate, and ovarian expression of VEGF, visfatin, c-Kit, BMP-15, and GDF-9 at both doses. However, ovarian expression of Sirt1 and Sirt2 was increased at 53.0 mg/kg of PL. ROS levels were not affected by PL. These results suggest that PL may possess beneficial effects regarding ovarian function and oocyte quality, possibly by activation of ovarian angiogenesis and follicular development.

Abstract
This paper serves to fill a gap in the literature regarding evidence for the use of botanical remedies in the promotion of fertility. It examines the botanical remedies that were used in North America (1492-1900) for all stages of reproduction from preconception to birth, and discusses their potential for future use with present-day infertility treatments. Each medicinal plant discussed in this paper is assessed using an ethnomedicinal methodology that entails examining the published ethnobotanical, phytochemical and pharmacological data. A few clinical trials have shown that there is potential for medicinal plants to improve the success rate of assisted reproductive technology (ART) treatment if used in an integrated manner, similar to the integrated use of traditional Chinese medicine with ART treatment. For example, research has shown that older women who become pregnant have a high miscarriage rate, and this is one area that complementary and alternative medicines can address.

Abstract
BACKGROUND Management of women with reduced ovarian reserve or poor ovarian response (POR) to stimulation is one of the major challenges in reproductive medicine. The primary causes of POR remain elusive and oxidative stress was proposed as one of the important contributors. It has been suggested that focus on the specific subpopulations within heterogeneous group of poor responders could assist in evaluating optimal management strategies for these patients. This study investigated the effect of anti-oxidant treatment with coenzyme Q10 (CoQ10) on ovarian response and embryo quality in young low-prognosis patients with POR. METHODS This prospective, randomized controlled study included 186 consecutive patients with POR stratified according to the POSEIDON classification group 3 (age < 35, poor ovarian reserve parameters). The participants were randomized to the CoQ10 pre-treatment for 60 days preceding IVF-ICSI cycle or no pre-treatment. The number of high quality embryos was a primary outcome measure. RESULTS A total of 169 participants were evaluated (76 treated with CoQ10 and 93 controls); 17 women were excluded due to low compliance with CoQ10 administration. The baseline demographic and clinical characteristics were comparable between the groups. CoQ10 pretreatment resulted in significantly lower gonadotrophin requirements and higher peak E2 levels. Women in CoQ10 group had increased number of retrieved oocytes (4, IQR 2-5), higher fertilization rate (67.49%) and more high-quality embryos (1, IQR 0-2); p < 0.05. Significantly less women treated with CoQ10 had cancelled embryo transfer because of poor embryo development than controls (8.33% vs. 22.89%, p = 0.04) and more women from treatment group had available cryopreserved embryos (18.42% vs. 4.3%, p = 0.012). The clinical pregnancy and live birth rates per embryo transfer and per one complete stimulation cycle tended to be higher in CoQ10 group but did not achieve statistical significance. CONCLUSION Pretreatment with CoQ10 improves ovarian response to stimulation and embryological parameters in young women with poor ovarian reserve in IVF-ICSI cycles. Further work is required to determine whether there is an effect on clinical treatment endpoints.

Abstract
PURPOSE We investigated antioxidant effects of CoQ10 supplementation on the prevention of OS-induced ovarian damage and to evaluate the protective effect of such supplementation against OS-related DNA damage. METHODS Twenty-four adult female Sprague-Dawley rats were randomly divided into three groups (8 rats per group): group 1 (control): saline, ip, and orally; group 2 (cisplatin group): cisplatin, 4.5 mg/kg ip, two times with an interval of 7 days; and group 3 (cisplatin + CoQ10 group): cisplatin, 4.5 mg/kg ip, two times with an interval of 7 days, and 24 h before cisplatin, 150 mg/kg/day orally in 1 mL of saline daily for 14 days. Serum concentrations of anti-Mullerian hormone (AMH), number of AMH-positive follicles, the assessment of the intensity of 8'OHdG immunoreactivity, the primordial, antral and atretic follicle counts in the ovary were assessed. RESULT(S) The mean serum AMH concentrations were 1.3 ± 0.19, 0.16 ± 0.03, and 0.27 ± 0.20 ng/mL in groups 1, 2, and 3, respectively (p < 0.01). Serum AMH levels were significantly higher in group 1 compared to groups 2 and 3 (p < 0.01 and p = 0.01, respectively). There was a statistically significant difference in AMH-positive follicle count between the groups (p < 0.01). Group 1 showed higher numbers of AMH-positive granulosa cells compared to group 2 (p = 0.01). A significant difference was found in the primordial, the atretic, and antral follicle counts between the three groups (p < 0.01, p < 0.01, and p < 0.01, respectively). The atretic follicle count was significantly lower in the cisplatin plus CoQ10 group compared to the cisplatin group (p < 0.01). The antral follicle counts were significantly higher in the cisplatin plus CoQ10 group compared with the cisplatin group (p < 0.01). There was a statistically significant difference in the intensity of staining of the follicles that were positive for anti-8'OHdG between the groups (p = 0.02). Group 1 showed a significant lower intensity of staining of the follicles positive for anti-8'OHdG compared with group 2 (p = 0.03). CONCLUSION(S) CoQ10 supplementation may protect ovarian reserve by counteracting both mitochondrial ovarian ageing and physiological programmed ovarian ageing although the certain effect of OS in female infertility is not clearly known.

Abstract
In humans, the risk of operative first delivery increases linearly with maternal age. We previously hypothesized that prolonged, cyclical, prepregnancy exposure to estrogen and progesterone contributes to uterine aging. Here, we test this hypothesis. Myometrium was obtained from four groups of virgin mice: (i) 10- to 12-week- and 28- to 30-week-old mice; (ii) 10- to 12-week- and 38- to 40-week-old mice; (iii) 38-week-old mice that had an ovariectomy or sham operation early in life; (iv) 38-week-old mice that had been treated with progesterone or vehicle containing implants from 8 to 36 weeks. Transcript profiling was carried out using Affymetrix Gene ST 1.1 arrays, and data were normalized. We identified 60 differentially regulated transcripts associated with advancing age (group 1). We validated these changes in group 2 (P for overlap = 5.8 × 10(-46) ). Early ovariectomy prevented the age-related changes in myometrial transcript profile. Similarly, progesterone-mediated long-term ovarian suppression prevented the age-related changes in myometrial transcript profile. Interferon regulatory factor 7 (Irf7) mRNA was regulated by age and hormonal exposure, and was identified as a predicted regulator of the other differentially expressed transcripts by both promoter sequence and canonical pathway activation analysis (P = 8.47 × 10(-5) and P < 10(-10) , respectively). Immunohistochemistry demonstrated IRF7 in both mouse and human myometrium. We conclude the following: (i) Myometrial aging in mice is associated with reproducible changes in transcript profile; (ii) these changes can be prevented by interventions which inhibit cyclical changes in the female sex hormones; and (iii) IRF7 may be an important regulator of myometrial function and aging.

Sirtuin Functions in Female Fertility: Possible Role in Oxidative Stress and Aging. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2015; 2015:659687.

Abstract
In search for strategies aimed at preventing oxidative threat to female fertility, a possible role of sirtuins has emerged. Sirtuins (silent information regulator 2 (Sir2) proteins), NAD(+) dependent enzymes with deacetylase and/or mono-ADP-ribosyltransferase activity, are emerging as key antiaging molecules and regulators in many diseases. Recently, a crucial role for SIRT1 and SIRT3, the main components of sirtuin family, as sensors and guardians of the redox state in oocytes, granulosa cells, and early embryos has emerged. In this context, the aim of the present review is to summarize current knowledge from research papers on the role of sirtuins in female fertility with particular emphasis on the impairment of SIRT1 signalling with oocyte aging. On this basis, the authors wish to build up a framework to promote research on the possible role of sirtuins as targets for future strategies for female fertility preservation.

Abstract
BACKGROUND Given the established relation between testosterone and aging in older adults, we tested whether buccal telomere length (TL), an established cellular biomarker of aging, was associated with testosterone levels in youth. METHODS Children, mean age 10.2 years, were recruited from the greater New Orleans area, and salivary testosterone was measured diurnally and during an acute stressor. Buccal TL was measured using monochrome multiplex quantitative real-time polymerase chain reaction. Testosterone and TL data were available on 77 individuals. The association between buccal TL and testosterone was tested using multivariate generalized estimating equations to account for clustering of children within families. RESULTS Greater peak testosterone levels (β = -0.87, P < 0.01) and slower recovery (β = -0.56, P < 0.01) and reactivity (β = -1.22, P < 0.01) following a social stressor were significantly associated with shorter buccal TL after controlling for parental age at conception, child age, sex, sociodemographic factors and puberty. No association was initially present between diurnal measurements of testosterone or morning basal testosterone levels and buccal TL. Sex significantly moderated the relation between testosterone reactivity and buccal TL. CONCLUSIONS The association between testosterone and buccal TL supports gonadal maturation as a developmentally sensitive biomarker of aging within youth. As stress levels of testosterone were significantly associated with buccal TL, these findings are consistent with the growing literature linking stress exposure and accelerated maturation. The lack of association of diurnal testosterone or morning basal levels with buccal TL bolsters the notion of a shared stress-related maturational mechanism between cellular stress and the hypothalamic pituitary gonadal axis. These data provide novel evidence supporting the interaction of aging, physiologic stress and cellular processes as an underlying mechanism linking negative health outcomes and early life stress.

Abstract
STUDY QUESTION Is SIRT1 involved in the oxidative stress (OS) response in mouse oocytes? SUMMARY ANSWER SIRT1 plays a pivotal role in the adaptive response of mouse germinal vesicle (GV) oocytes to OS and promotes a signalling cascade leading to up-regulation of the MnSod gene. WHAT IS KNOWN ALREADY OS is known to continuously threaten acquisition and maintenance of oocyte developmental potential during in vivo processes and in vitro manipulations. Previous studies in somatic cells have provided strong evidence for the role of SIRT1 as a sensor of the cell redox state and a protector against OS and aging. STUDY DESIGN, SIZE, DURATION GV oocytes obtained from young (4-8 weeks) and reproductively old (48-52 weeks) CD1 mice were blocked in the prophase stage by 0.5 µM cilostamide. Groups of 30 oocytes were exposed to 25 µM H2O2 and processed following different times for the analysis of intracellular localization of SIRT1 and FOXO3A, and evaluation of Sirt1, miRNA-132, FoxO3a and MnSod gene expression. Another set of oocytes was cultured in the presence or absence of the SIRT1-specific inhibitor Ex527, and exposed to H2O2 in order to assess the involvement of SIRT1 in the activation of a FoxO3a-MnSod axis and ROS detoxification. In the last part of this study, GV oocytes were maturated in vitro in the presence of different Ex527 concentrations (0, 2.5, 5, 10, 20 µM) and assessed for maturation rates following 16 h. Effects of Ex527 on spindle morphology and ROS levels were also evaluated. PARTICIPANTS/MATERIALS, SETTING, METHODS SIRT1 and FOXO3A intracellular distribution in response to OS was investigated by immunocytochemistry. Real-time RT-PCR was employed to analyse Sirt1, miR-132, FoxO3a and MnSod gene expression. Reactive oxygen species (ROS) production was evaluated by in vivo measurement of carboxy-H2DCF diacetate labelling. Spindle and chromosomal distribution in in vitro matured oocytes were analysed by immunocytochemistry and DNA fluorescent labelling, respectively. MAIN RESULTS AND THE ROLE OF CHANCE Specific changes in the intracellular localization of SIRT1 and up-regulation of Sirt1 gene were detected in mouse oocytes in response to OS. Moreover, increased intracellular ROS were observed when SIRT1 activity was inhibited by Ex527. In aged oocytes Sirt1 was expressed more than in young oocytes but SIRT1 protein was undetectable. Upon OS, significant changes in miR-132 micro-RNA, a validated Sirt1 modulator, were observed. A negative correlation between Sirt1 mRNA and miR-132 levels was observed when young oocytes exposed to OS were compared with young control oocytes, and when aged oocytes were compared with young control oocytes. FoxO3a and MnSod transcripts were increased upon OS with the same kinetics as Sirt1 transcripts, and up-regulation of MnSod gene was prevented by oocyte treatment with Ex527, indicating that SIRT1 acts upstream to the FoxO3a-MnSod axis. Finally, the results of the in vitro maturation assay suggested that SIRT1 might be involved in oocyte maturation by regulating the redox state and ensuring normal spindle assembly. LIMITATIONS, REASONS FOR CAUTION The main limitation of this study was the absence of direct quantification of SIRT1 enzymatic activity due to the lack of an appropriately sensitive method. WIDER IMPLICATIONS OF THE FINDINGS The present findings may provide a valuable background for studying the regulation of SIRT1 during oogenesis and its relevance as a sensor of oocyte redox state and energy status. The antioxidant response orchestrated by SIRT1 in oocytes seems to decrease with aging. This suggests that SIRT1 could be an excellent pharmacological target for improving oocyte quality and IVF outcome in aging or aging-like diseases.
