Gentisic acid attenuates 5-fluorouracil-induced ovotoxicity in rats via modulating Nrf2 signalling: An experimental approach. Reprod Toxicol 2024; 128:108661. [PMID: 38986848 DOI: 10.1016/j.reprotox.2024.108661] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2024] [Revised: 06/25/2024] [Accepted: 07/06/2024] [Indexed: 07/12/2024]
Abstract
5-Fluorouracil (5-FU) is the third most used chemotherapeutic in the world with its anticancer effect resulting from its potential to block DNA replication. Like other cytotoxic agents, 5-FU has side effects on healthy tissues, and the reproductive system is among the tissues most affected by these undesirable effects. Gentisic acid (GEA) is a secondary metabolite that is abundant in fruits, vegetables and spices and has antioxidant activity. This study was conducted to investigate the toxicity of 5-FU in rat ovarian tissue and to determine the therapeutic activity of GEA on ovotoxicity caused by 5-FU. The results showed that 5-FU caused histopathological findings by suppressing Nrf2 pathway and accordingly increasing oxidative stress, inflammation, endoplasmic reticulum stress and apoptosis. However, GEA treatments after 5-FU application ameliorated 5-FU-induced ovotoxicity dose-dependently through activation of Nrf2 pathway. All these findings provided strong evidence supporting the hypothesis that GEA treatment may have therapeutic effects against 5-FU-induced ovarian damage. However, the beneficial effect of GEA use in eliminating ovarian damage in women after 5-FU chemotherapy should continue to be investigated with more detailed molecular studies.

Abstract
OBJECTIVE To investigate the comprehensive effects of daily chronic asprosin administration on various pubertal and reproductive parameters in female rats. This study aims to elucidate the role of asprosin in regulating the onset of puberty and its influence on hormonal profiles and ovarian histology. METHODS Asprosin was administered intraperitoneally (i.p.) at a dose of 500 ng/kg daily for eight weeks. Hormonal assays and histological analyses were performed to evaluate the effects of asprosin on the onset of puberty and reproductive function. RESULTS Daily chronic administration of asprosin accelerated the onset of the first oestrus. Hormonal assays revealed significant elevations in serum levels of Follicle-Stimulating Hormone (FSH) and Oestradiol (E2), while Inhibin B levels decreased. Histological evaluations demonstrated an increased number of primary and secondary follicles in ovarian tissue, without affecting primordial follicle counts or reproductive organ weights. CONCLUSIONS Role of adipokines in regulating puberty and reproductive function has increasingly gained recognition. This study aimed to provide the first comprehensive examination of the effects of daily chronic asprosin administration on pubertal and reproductive parameters in female rats. Utilising hormonal assays and histological analyses, asprosin was administered intraperitoneally (i.p.) at a dose of 500 ng/kg, daily, for eight weeks. Our findings revealed that daily chronic administration of asprosin accelerated the onset of the first oestrus. Hormonal assays showed significant elevations in serum levels of Follicle-Stimulating Hormone (FSH) and Oestradiol (E2), while Inhibin B levels decreased. Histological evaluations demonstrated an increased number of primary and secondary follicles in ovarian tissue, without affecting primordial follicle counts or reproductive organ weights. These results provide new insights into asprosin's role in advancing the age of first oestrus and modulating hormonal profiles, thereby offering potential benefits to the female reproductive system.

Abstract
INTRODUCTION Chemotherapy is crucial in treating gestational trophoblastic neoplasia (GTN), but its impact on gonadotoxicity is unclear. MATERIALS AND METHODS This case-control study included 57 GTN patients and 19 age-matched patients with molar pregnancies (MP) in 2012-2018. Multiples of the median (MoM) of the serum AMH levels were compared between the two groups, and between patients using single-agent and combination chemotherapy, at baseline, 6, 12, and 24 months after treatment. Their pregnancy outcomes were also compared. RESULTS There was no significant difference in the MoM of serum AMH between GTN and MP groups at all time points. Single-agent chemotherapy did not adversely affect the MoM. However, those receiving combination chemotherapy had lower MoM than those receiving single-agent chemotherapy at all time points. The trend of decline from the baseline was marginally significant in patients with combination chemotherapy, but the drop was only significant at 12 months (Z = -2.69, p = 0.007) but not at 24 months (Z = -1.90; p = 0.058). Multivariable analysis revealed that combination chemotherapy did not affect the MoM. There was no significant difference in the 4-year pregnancy rate and the livebirth rate between the single-agent and combination groups who attempting pregnancy, but it took 1 year longer to achieve the first pregnancy in the combination group compared to the single-agent group (2.88 vs. 1.88 years). CONCLUSION This study showed combination chemotherapy led to a decreasing trend of MoM of serum AMH especially at 12 months after treatment, but the drop became static at 24 months. Although pregnancy is achievable, thorough counseling is still needed in this group especially those wish to achieve pregnancy 1-2 years after treatment or with other risk factors.

Abstract
RESEARCH QUESTION How do anti-Müllerian hormone (AMH) concentrations in women with and without arthritis compare? Is there an association between AMH and arthritis drug regimen? DESIGN In this prospective cohort study, AMH was measured at two time points (T0 and T1) in 129 premenopausal women with arthritis. AMH at T0 was compared with that from a bank of serum samples from 198 premenopausal women without arthritis. Primary outcomes were: (i) diminished ovarian reserve (DOR) (AMH <1.1 ng/ml) and (ii) annual rate of AMH decrease. Univariate, multivariable and Firth logistic regression identified variables associated with annual AMH decrease in excess of the 75th percentile. RESULTS Median time between T0 and T1 was 1.72 years. At time T0, median age-adjusted AMH in women with arthritis was significantly lower than that of women without arthritis (median 2.21 ng/ml versus 2.78 ng/ml; P = 0.009). Women with arthritis at highest risk for DOR had a history of tubal sterilization or were over the age of 35. Those with highest odds of having an annual AMH decrease in excess of the 75th percentile (over 28% decrease per year) were those: over the age of 35 or who sought care for infertility. Women with arthritis taking methotrexate alone (OR 0.08, 95% CI 0.01-0.67) or methotrexate plus tumour necrosis factor-alpha antagonists (OR 0.13, 95% CI 0.02-0.89) were less likely to be in the highest quartile of annual AMH decrease than women with arthritis not taking medication. CONCLUSIONS Women with arthritis had lower AMH than healthy controls. Long-term methotrexate use was not associated with an annual AMH decrease.

Abstract
PURPOSE The purpose of the study was to explore the possible deleterious effects of Methotrexate (MTX) treatment on the urogenital tissues and the potential protective effects of Astaxanthin (AXA). METHODS Twenty-four female Wistar Albino rats (12 months old) were divided into 3 groups as follows: Group I (Control group): rats received a single dose of 0.1 ml saline by gavage and intraperitoneal injection. Group II (MTX group): rats received a single dose of 20 mg/kg MTX, i.p, on the 2nd day. Group III (MTX + AXA group): rats received 100 mg/kg AXA orally for 7 days in addition to a single dose of MTX. The levels of total oxidant status (TOS), total antioxidant status (TAS), oxidative stress index (OSI), and histopathological and immunohistochemical markers (Caspase-3, iNOS, CRP, G-CSF) were evaluated in urogenital tissues. RESULTS In ovarian tissues, a statistically significant increase in TOS levels (p = 0.001) and OSI index (p = 0.028) were observed in Group II compared to Group I. TAS level was significantly higher in Group III compared to Group II and I (p = 0.009 and 0.002, respectively). However, a significant decrease in OSI level was observed in Group III compared to Group II (p = 0.035). In fallopian tube tissues, TAS level was significantly decreased in Group II compared to Group I (p = 0.047). Histopathologically, marked hyperemia was observed in MTX group. AXA treatment ameliorated all the pathological findings. Immunohistochemically, all the studied markers were considerably increased in Group II, however, they were decreased by AXA. CONCLUSION These findings revealed that MTX treatment caused oxidative stress, apoptosis, and inflammation in the urogenital tissue. We found that AXA significantly ameliorated the damage caused by MTX in the urogenital tissue. The results of the study have indicated that AXA may be a promising nutritional support substance against the damage caused by chemotherapeutic and cytotoxic agents, such as MTX, to the urogenital tissue.

Abstract
Introduction Adalimumab is used in the treatment of many chronic inflammatory diseases, especially rheumatoid arthritis. The aim of this experimental study is to determine the histological and biochemical effects of adalimumab on rat ovary. Methods Wistar albino female rats were randomly divided into three groups prior to the experiment: a healthy control group, a 2 mg/kg adalimumab group, and a 5 mg/kg adalimumab group. Then, histopathological findings and biochemical examinations were made in the ovaries of the rats. Hematoxylin-eosin staining, morphometric examination, and Masson trichrome staining were performed. Antimullerian hormone (AMH) levels were measured in the biochemical examination. Results Ovarian follicle count and AMH level were significantly higher in the groups given low-dose adalimumab and high-dose adalimumab (p <0.001). In addition, fibrosis decreased in proportion to the dose of adalimumab (p <0.001). Conclusion Adalimumab is an important biological agent that contributes to the preservation of ovarian function by increasing ovarian follicle reserve and has shown that it can help preserve ovarian reserve in women of reproductive age suffering from chronic inflammatory diseases.

Abstract
Background: Methotrexate (MTX), which is the anchor drug in rheumatoid arthritis (RA), targets actively proliferating cells including the oocytes and granulosa cells which may impair the ovarian reserve. The purpose of this study was to determine the effects of MTX therapy on gonadotropic hormones, i.e. follicular stimulating hormone (FSH) and luteinizing hormone (LH) in female RA patients of reproductive age. Materials and methods: This is a cross-sectional study conducted at the Universiti Kebangsaan Malaysia Medical Centre (UKMMC), from January 2018 to July 2018. Women with RA aged between 15 and 49 years who were on MTX therapy for at least six months, were consecutively recruited. All subjects were interviewed to gather information on their menstrual history and menopausal symptoms. The medical records were reviewed to obtain further data on the disease characteristics and RA treatment. The RA disease activity was determined using the DAS 28 scoring system. All subjects were tested for their serum FSH and LH levels. Results: A total of 40 patients were included in this study. The median dose of MTX used by the subjects was 12.5 mg weekly. The mean cumulative MTX dose was 1664.92 ± 738.61 mg. More than half (53.1%) of the subjects reported menopausal symptoms especially hot flushes. We found that FSH levels had a significant positive correlation with cumulative MTX dose [(r = 0.86), p < 0.001] and the duration of MTX therapy [(r = 0.84), p < 0.001]. Besides, there was a significant relationship between disease activity based on DAS 28 and FSH levels (p < 0.01). Age, body mass index, disease duration, and weekly MTX dose showed no associations with the FSH levels. On multivariate analysis, DAS 28 was found to be the only parameter that remained significant [β = 1.74 (95% CI 1.17-2.31), p < 0.001]. The LH levels, on the other hand, were not associated with MTX therapy or disease activity. Conclusion: Higher levels of FSH, which is an indicator of diminished ovarian reserve, have a significant positive relationship with disease activity, cumulative dose, and duration of MTX therapy in RA.

Abstract
It is widely known that not only the gonadal estradiol (E2) but also hippocampal E2 plays an essential role in memory process. However, the role of hippocampal E2-enhanced memory mechanism during aging is largely unknown. The aim of the present study was to investigate the effect of age on E2 concentration, the expression level of its receptors, and key steroidogenic enzymes in hippocampus. We also investigated the effect of microglia activation on E2 synthesis in hippocampal neurons. The results showed that serum E2 was higher in 19-month-old (aged) rats, which exhibited spatial memory decline in the Morris water maze (MWM) test when compared to the younger rats. Hence, serum E2 may not be associated with the reduced spatial memory performance in aging. In contrast, the level of E2 and the expressions of its receptors were significantly decreased in hippocampus of aged female rat compared to younger females. Furthermore, the expressions of key hippocampal steroidogenic enzymes, steroidogenic acute regulatory protein (StAR), and cytochrome P450 (P450) also significantly decreased with age, which resulted in lower hippocampal E2 levels. In addition, we found that the microglia of aged brain highly expressed interleukin 6 (IL-6), which directly inhibited E2 synthesis in hippocampal neurons via suppression of P450 synthesis. Taken together, we summarized that the microglia-derived IL-6 inhibited hippocampal E2 synthesis in aged rats which, in turn, contributed to the deficit of spatial memory performance.

Abstract
To determine whether the possible oxidative effect of methotrexate (Mtx) on ovary and to evaluate the effectiveness of alpha lipoic acid (ALA), which may be useful in many oxidative stress models. Thirty-two female Wistar-albino rats were randomly divided into four groups; control group, alpha lipoic acid group (ALA 100 mg/kg, 10 days), multiple dose Mtx group (Mtx 1 mg/kg 1, 3, 5, 7 days) and Mtx and ALA group (Mtx 1 mg/kg 1, 3, 5, 7 days and ALA 100 mg/kg, 10 days). Serum total antioxidant status (TAS), total oxidant status (TOS) and oxidative stress index (OSI), tumor necrosis factor-alpha (TNF-α), tissue malondialdehyde (MDA) and activities of glutathione peroxidase (GSH-Px) and catalase (CAT) and anti-Mullerian hormone (AMH) and total ovarian follicle count were evaluated. Mtx administration caused a significant decrease in TAS, a significant increase in TOS and OSI, a significant increase in MDA levels and a decrease in GSH-Px and CAT activity. Moreover the proinflammatory cytokine (TNF-α) was increased in the Mtx group. And AMH values and total follicle count were significantly decreased in Mtx group. However, ALA treatment reversed biochemical results and AMH levels and total follicle count. Alpha lipoic acid ameliorates methotrexate induced oxidative damage of ovarian in rats.

Abstract
PURPOSE The purpose of this research was to study whether methotrexate (MTX) as treatment for ectopic pregnancy (EP) impacts the future fertility of women undergoing assisted reproductive technology (ART) METHODS: In a systematic review and multi-center retrospective cohort from four academic and private fertility centers, 214 women underwent an ART cycle before and after receiving MTX as treatment for an EP. Measures of ovarian reserve and responsiveness and rates of clinical pregnancy (CP) and live birth (LB) were compared in the ART cycles prior and subsequent to MTX. RESULTS Seven studies were identified in the systematic review, and primary data from four institutions was included in the final analysis. Women were significantly older in post-MTX cycles (35.3 vs 34.7 years). There were no differences in follicle stimulating hormone, antral follicle count, duration of stimulation, oocytes retrieved, or fertilization rate between pre- and post-MTX cycles. However, post-MTX cycles received a significantly higher total dose of gonadotropins (4206 vs 3961 IU). Overall, 42 % of women achieved a CP and 35 % achieved a LB in the post-MTX ART cycle, which is similar to national statistics. Although no factors were identified that were predictive of LB in young women, the number of oocytes retrieved in the previous ART cycle and current AFC were predictive of LB (AUC 0.76, 0.75) for the older women. CONCLUSIONS MTX does not influence ovarian reserve, response to gonadotropin stimulation, and CP or LB rate after ART. MTX remains a safe and effective treatment option for women with asymptomatic EPs.
