The mollifying effect of Sambucus nigra extract on StAR gene expression, oxidative stress, and apoptosis induced by fenpropathrin in male rats. Food Chem Toxicol 2024; 189:114744. [PMID: 38782235 DOI: 10.1016/j.fct.2024.114744] [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: 02/27/2024] [Revised: 04/03/2024] [Accepted: 05/16/2024] [Indexed: 05/25/2024]
Abstract
Fenpropathrin (FNP) is a man-made insecticide of to the pyrethroid class, commonly employed in agricultural and horticultural practices. However, it has a prolonged persistence in the environment. Sambucus nigra, also referred to as SN, is a botanical species recognized for its notable antioxidant characteristics. The objective of this study was to examine if SN extract could mitigate the reproductive toxicity induced by FNP in rats. A total of thirty rats were categorized into six distinct groups: a control group with no treatment, two groups getting SN extract at varying doses, a group receiving FNP, and two groups receiving both FNP and SN extract. The exposure to FNP led to a decline in the number and movement of sperm, lowered levels of testosterone, and reduced the activity of the StAR gene in the FNP group compared to the control group (p < 0.05). In addition, FNP resulted in a significant increase in malondialdehyde levels with a significant drop in GSH content compared to the control group (p < 0.05). Also, a significant increase in the expression of caspase 3. Nevertheless, the administration of SN extract alleviated these effects and reinstated spermatogenesis, thereby bringing the parameters closer to those observed in the control group. The data indicate that FNP can induce testicular harm and infertility, but SN extract can mitigate these detrimental consequences.

Abstract
Context Carbon tetrachloride (CCl4 ) is a chemical that is still widely used in industry and has been shown to cause structural defects in rat testicles through oxidative stress. Aims In our study, the effect of curcumin on CCl4 -mediated testicular damage was investigated. Methods Twenty-four adult Wistar albino male rats weighing 300-350g were divided into four groups: control group (olive oil was applied by gavage every consecutive day for 3weeks); curcumin and CCl4 +curcumin groups (200mg/kg curcumin dissolved in olive oil was given by gavage once a day, every consecutive day for 3weeks); and CCl4 and CCl4 +curcumin groups (0.5mL/kg CCl4 was dissolved in olive oil at a ratio of 1/1 and given by i.p. injection every other day for 3weeks). Tissue samples were examined histopathologically, histomorphometrically, immunohistochemically and biochemically. Key results CCl4 disrupted both testicular morphology and testosterone synthesis, whereas curcumin treatment resulted in an improvement in testicular morphology and biochemical parameters, as well as a decrease in caspase-3 and tumour necrosis factor-α expression. Conclusions Curcumin has a protective effect on testicular tissue damage caused by CCl4 with its anti-inflammatory, antiapoptotic and antioxantioxidant properties. Implications Curcumin can prevent testicular damage due to CCl4 , an environmental pollutant.

Abstract
Redox balance plays an important role in testicular homeostasis. While lots of antioxidant molecules have been identified as widely expressed, the understanding of the critical mechanisms for redox management in male germ cells is inadequate. This study identified LanCL2 as a major male germ cell-specific antioxidant gene that is important for testicular homeostasis. Highly expressed in the brain and testis, LanCL2 expression correlates with testicular maturation and brain development. LanCL2 is enriched in spermatocytes and round spermatids of the testis. By examining LanCL2 knockout mice, we found that LanCL2 deletion did not affect postnatal brain development but injured the sperm parameters of adult mice. With histopathological analysis, we noticed that LanCL2 KO caused a pre-maturation and accelerated the self-renewal of spermatogonial stem cells in the early stage of spermatogenesis. In contrast, at the adult stage, LanCL2 KO damaged the acrosomal maturation in spermiogenesis, resulting in spermatogenic defects with a reduced number and motility of spermatozoa. Furthermore, we show that this disruption of testicular homeostasis in the LanCL2 KO testis was due to dysbalanced testicular redox homeostasis. This study demonstrates the critical role of LanCL2 in testicular homeostasis and redox balance.

Abstract
The prevalence of substance use globally is rising and is highest among men of reproductive age. In Africa, and South and Central America, cannabis use disorder is most prevalent and in Eastern and South-Eastern Europe, Central America, Canada and the USA, opioid use disorder predominates. Substance use might be contributing to the ongoing global decline in male fertility, and emerging evidence has linked paternal substance use with short-term and long-term adverse effects on offspring development and outcomes. This trend is concerning given that substance use is increasing, including during the COVID-19 pandemic. Preclinical studies have shown that male preconception substance use can influence offspring brain development and neurobehaviour through epigenetic mechanisms. Additionally, human studies investigating paternal health behaviours during the prenatal period suggest that paternal tobacco, opioid, cannabis and alcohol use is associated with reduced offspring mental health, in particular hyperactivity and attention-deficit hyperactivity disorder. The potential effects of paternal substance use are areas in which to focus public health efforts and health-care provider counselling of couples or individuals interested in conceiving.

Abstract
The human immunodeficiency virus continues to pose a significant global public health challenge, affecting millions of individuals. The current treatment strategy has incorporated the utilization of combinations of antiretroviral drugs. The administration of these drugs is associated with many deleterious consequences on several physiological systems, notably the reproductive system. This study aimed to assess the toxic effects of abacavir sulfate, ritonavir, nevirapine, and zidovudine, as well as their combinations, on TM3 Leydig and TM4 Sertoli cells. The cell viability was gauged using 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide (MTT) and neutral red uptake (NRU) assays. Reactive oxygen species (ROS) production was assessed via the 2',7'-dichlorofluorescein diacetate (DCFDA) test, and DNA damage was determined using the comet assay. Results indicated cytotoxic effects at low drug concentrations, both individually and combined. The administration of drugs, individually and in combination, resulted in the production of ROS and caused damage to the DNA at the tested concentrations. In conclusion, the results of this study suggest that the administration of antiretroviral drugs can lead to testicular toxicity by promoting the generation of ROS and DNA damage. Furthermore, it should be noted that the toxicity of antiretroviral drug combinations was shown to be higher compared to that of individual drugs.

Abstract
Superoxide dismutases (SODs) are antioxidant enzymes that protect cells from oxidation. Three SODs have been identified in mammals, but there is limited information in teleosts. This study investigates SODs in the European eel and their expression patterns during testis maturation. Phylogenetic and synteny analyses revealed SODs paralogs and their evolution in vertebrates. The eel possesses one SOD1 and two SOD2/3 (a and b), indicating SOD2 and SOD3 duplication in elopomorphs. SODs expression were then evaluated in various male and female tissues. SOD1 is more expressed in females, while SOD2a and SOD2b dominate brain-pituitary-gonad tissues in both sexes. SOD3a showed predominant expression in the ovary and the male livers, whereas SOD3b was found in the pituitary and brain of both sexes. The effects of different maturation protocols (standard hormonal treatment vs. same protocol preceded with cold seawater pre-treatment) on SODs expression during testis maturation were evaluated. Salinity increase at the onset of standard treatment at 20 °C, simulating early migration, upregulated SOD1, SOD2a, and SOD2b, coinciding with spermatogonia type A differentiated cells dominance. Thereafter, SOD2a and SOD3a decreased, while SOD2b increased during hormonal treatment-induced spermatogenesis. Pre-treatment with seawater at 10 °C, mimicking the conditions at the beginning of the seawater migration, downregulated SOD1 but increased SOD3a expression. Finally, the standard hormonal treatment, replicating spawning at higher temperatures, downregulated SOD1 in eels without any pre-treatment while SOD2a expression increased in pre-treated eels. This study revealed tissue-specific, sex-dependent, and maturation-related SOD expression patterns, predicting SODs dynamic expression profiles during their reproductive migration.

Abstract
Zinc (Zn) is an important trace element in the human body and plays an important role in growth, development, and male reproductive functions. Marginal zinc deficiency (MZD) is common in the human population and can cause spermatogenic dysfunction in males. Therefore, the aim of this study was to investigate methods to improve spermatogenic dysfunction caused by MZD and to further explore its mechanism of action. A total of 75 4-week-old male SPF ICR mice were randomly divided into five groups (control, MZD, MZD + ZnY2, MZD + ZnY4, and MZD + ZnY8, 15 mice per group). The dietary Zn content was 30 mg/kg in the control group and 10 mg/kg in the other groups. From low to high, the Zn supplementation doses administered to the three groups were 2, 4, and 8 mg/kg·bw. After 35 days, the zinc content, sperm quality, activity of spermatogenic enzymes, oxidative stress level, and apoptosis level of the testes in mice were determined. The results showed that MZD decreased the level of Zn in the serum, sperm quality, and activity of spermatogenic enzymes in mice. After Zn supplementation, the Zn level in the serum increased, sperm quality was significantly improved, and spermatogenic enzyme activity was restored. In addition, MZD reduced the content of antioxidants (copper-zinc superoxide dismutase (Cu-Zn SOD), metallothionein (MT), and glutathione (GSH) and promoted malondialdehyde (MDA) production. The apoptosis index of the testis also increased significantly in the MZD group. After Zn supplementation, the level of oxidative stress decreased, and the apoptosis index in the testis was reduced. Furthermore, quantitative real-time polymerase chain reaction (qRT-PCR) showed that the expression of B-cell lymphoma-2 (Bcl-2) mRNA and Bcl-2/BCL2-associated X (Bax) in the control group decreased in testicular cells, and their expression was restored after Zn supplementation. The results of this study indicated that Zn supplementation can reduce the level of oxidative stress and increase the ability of testicular cells to resist apoptosis, thereby improving spermatogenic dysfunction caused by MZD in mice.

Abstract
It is well known that the epididymis promotes post-testicular sperm maturation events. However, its malfunction during congenital hypothyroidism is relatively less understood as compared to the testis. The present study evaluated the probable effect of α-lipoic acid on epididymal oxidative stress parameters in rats exposed to antithyroid drug, carbimazole during fetal period. Time-mated pregnant rats in unexposed and carbimazole (1.35 mg/Kg body weight exposed were allowed to deliver pups and weaned. At postnatal day 100, the F1 male pups were assessed for epididymal endpoints. Among the epididymal regions, significant elevation of lipid peroxidation levels, superoxide anion, and hydrogen peroxide contents with a concomitant reduction in the activity levels of superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase and reduced glutathione levels were observed in cauda epididymis of carbimazole exposed rats over controls. Significant elevation in sperm DNA fragmentation (comet assay), accelerated cauda epididymal sperm transit time and reduction in epididymal sialic acid content was observed in carbimazole exposed rats. RT-qPCR studies revealed that embryonic exposure to carbimazole resulted in down regulation of androgen receptor, nuclear factor eryrthoid 2 like 2, 5α-reducatse 1 mRNA levels, while up regulation of caspase 3 mRNA was observed in epididymal regions of rats. In addition, fetal exposure to carbimazole resulted in disorganization of cauda epididymal architecture in rats. Conversely, supplementation of α-lipoic acid (70 mg/Kg bodyweight) during PND 3 to 14 restored epididymal functions in carbimazole exposed rats and the ameliorative effects of lipoic acid could be attributed to its antioxidant and steroidogenic effects.

Abstract
Estrogens are hormones that play an important role in the digestive tract, including in men. Letrozole is an inhibitor of cytochrome P450 aromatase, an enzyme converting androgens to estrogens. The use of letrozole may cause oxidative stress and endoplasmic reticulum stress in the cells. Factors modulating cellular stress may include vitamin C. The purpose of this study was to examine whether letrozole and/or vitamin C supplementation can affect the morphology of the small intestine, the parameters of endoplasmic reticulum stress, programmed cell death markers, and oxidative damage. Three-month-old male rats were divided into four groups and treated with the following: (I) CTRL-water; (II) CTRL+C-L-ascorbic acid; (III) LET-letrozole; and (IV) LET+C-letrozole + L-ascorbic acid. The morphometrical measurements included epithelial thickness, crypt and lumen area, crypt perimeter, nuclei number in the crypt, and the cell size of crypts. The expression levels of PERK, caspase-3, and catalase were determined. Significant differences in the morphometrical measurements and immunoexpression were observed. This may indicate that chronic treatment with letrozole can affect morphology and induce ER stress, oxidative stress, and programmed cell death in the epithelial cells of the small intestine of adult male rats. Vitamin C supplementation exerts an effect on some parameters of the molecular processes.

Beneficial effect of honokiol and magnolol on polyol pathway and oxidative stress parameters in the testes of diabetic rats. Biomed Pharmacother 2024; 172:116265. [PMID: 38364735 DOI: 10.1016/j.biopha.2024.116265] [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: 09/18/2023] [Revised: 02/06/2024] [Accepted: 02/06/2024] [Indexed: 02/18/2024] Open
Abstract
In diabetes hyperglycemia, excessive production of free radicals and present oxidative stress lead to many complications in the body, including male reproductive system disorders. To prevent the development of diabetic complications in the testes resulting from them, it seems beneficial to include compounds considered as natural antioxidants. Honokiol and magnolol are neolignans obtained from magnolia bark, which possess proven antioxidant properties. The aim of this study was to evaluate the effect of honokiol and magnolol on the parameters of oxidative stress, polyol pathway and glycation products in the testes as well as on selected biochemical parameters in the blood serum of rats with type 2 diabetes. The study was conducted on mature male Wistar rats with high fat diet and streptozotocin-induced type 2 diabetes. Neolignans-treated rats received honokiol or magnolol orally at the doses of 5 or 25 mg/kg, respectively, for 4 weeks. Parameters related to glucose and lipid homeostasis, basic serological parameters and sex hormones level in the serum as well as polyol pathway parameters, antioxidant enzyme activity, endogenous antioxidants level, sumaric parameters for oxidative stress and oxidative damage in the testes were estimated. Oral administration of honokiol and magnolol turned out to be beneficial in combating the effects of oxidative stess in the testes, but showed no favorable effects on serum biochemical parameters. Additionally, magnolol compared to honokiol revealed more advantageous impact indicating the reversal of the effects of diabetic complications in the male reproductive system and counteracted oxidative stress damages and polyol pathway disorders in the testes.

Abstract
PURPOSE Varicocele has been associated with high seminal oxidative stress (OS), impaired semen quality, and reduced male fertility potential. However, the exact mechanism(s) underlying the development of varicocele-mediated infertility and the cause-effect relationship between varicocele and testicular dysfunction are not fully understood. The aim of this systematic review and meta-analysis (SRMA) is to investigate the impact of varicocele on testicular OS markers and sperm parameters in experimental animals with varicocele as compared to animals without varicocele. MATERIALS AND METHODS A literature search was performed using the Scopus and PubMed databases on studies that investigated testicular OS markers and sperm parameters in animals with varicocele. The primary outcomes included malondialdehyde (MDA) (nmol/mg) levels whereas the secondary outcomes included total sperm count (×106), sperm vitality (%), total sperm motility (%), and sperm DNA fragmentation (SDF) (%). Standardized mean difference (SMD) (95% confidence interval [CI]) was chosen to express the effect size. The quality of the included studies was evaluated using the Cambridge Quality Checklist. RESULTS Out of 76 identified articles, 6 studies on rats were included in the meta-analysis. The analysis showed a significant increase of MDA (SMD: 15.61 [1.93, 29.29]; p=0.03) in rats with varicocele vs. controls. We also observed a significant decrease in total sperm count (SMD: -17.45 [-28.97, -5.93]; p<0.01), sperm vitality (SMD: -16.41 [-26.30, -6.52]; p<0.01), total sperm motility (SMD: -17.67 [-24.90, -10.44]; p<0.01), and a significant increase of SDF (SMD: 7.41 [1.23, 13.59]; p=0.02), in rats with varicocele vs. controls. The quality of the included studies was ranked as high. CONCLUSIONS This SRMA indicates a significant increase in levels of testicular MDA and SDF and a reduction of sperm quality in experimental animals with varicocele. These findings support the potential role of testicular OS in the development of varicocele-induced testicular damage.

Abstract
Currently, most men with infertility cannot be given an aetiology, which reflects a lack of knowledge around gamete production and how it is affected by genetics and the environment. A failure to recognize the burden of male infertility and its potential as a biomarker for systemic illness exists. The absence of such knowledge results in patients generally being treated as a uniform group, for whom the strategy is to bypass the causality using medically assisted reproduction (MAR) techniques. In doing so, opportunities to prevent co-morbidity are missed and the burden of MAR is shifted to the woman. To advance understanding of men's reproductive health, longitudinal and multi-national centres for data and sample collection are essential. Such programmes must enable an integrated view of the consequences of genetics, epigenetics and environmental factors on fertility and offspring health. Definition and possible amelioration of the consequences of MAR for conceived children are needed. Inherent in this statement is the necessity to promote fertility restoration and/or use the least invasive MAR strategy available. To achieve this aim, protocols must be rigorously tested and the move towards personalized medicine encouraged. Equally, education of the public, governments and clinicians on the frequency and consequences of infertility is needed. Health options, including male contraceptives, must be expanded, and the opportunities encompassed in such investment understood. The pressing questions related to male reproductive health, spanning the spectrum of andrology are identified in the Expert Recommendation.

Abstract
The aim of this experiment was to find out whether the taurine supplementation in daily ration had an effect on quantity or quality of Duroc boar ejaculate. The experiment duration was from June to August, when it could assumed the possible occurrence of heat stress. For the study was chosen 12 Duroc boars of approximately the same age and condition. The control group of 6 Duroc boars was fed only by basic diet and the experimental group of 6 Duroc boars was fed by the same basic diet with supplementation of 15 g taurine/boar/day. Ejaculate was collected once a week by hand glowed technique. From ejaculate parameters were monitored volume of ejaculate, sperm concentration, total amount of sperm, morphologically abnormal sperm, taurine concentration and GSH/GSSH concentration. From microscopic analysis, results were statistically significant in motility in June and July (P<0.05). In biochemical results, a significant difference (P<0.05) has been found between the experimental groups in the concentrations of taurine as well as GSH/GSSG in ejaculate which indicates the effect of heat stress on boars during the experimental period.

Abstract
A growing interest has been drawn to the use of traditional medicinal plants for the treatment of human diseases and, in particular, infertility and reproductive toxicity associated with environmental factors. The Mediterranean basin area is a recognized source of plant species with therapeutic interest. In this frame, Eruca sativa (ES) is an annual edible plant and a member of the Brassicaceae family. A relatively large number of studies, focusing on the biological effects of the extract from the leaves of ES on in vitro and in vivo models of disease, have been published in recent years. The present narrative review aims to analyze the phytochemical constituents, traditional uses, possible pharmacological activities, and recognized effects of ES on male reproductive outcomes. Available investigations have revealed the presence of a number of compounds with antioxidant properties, such as polyphenols, glucosinolates, flavonoids, and carotenoids in extracts from ES. Based on the chemical and pharmacological characteristics of the aforementioned compounds, we show that ES has possible preventive properties and therapeutic uses, especially in the functional derangements of the male reproductive system.

G Protein-Coupled Estrogen Receptor (GPER) and ERs Are Modulated in the Testis-Epididymal Complex in the Normal and Cryptorchid Dog. Vet Sci 2024; 11:21. [PMID: 38250927 PMCID: PMC10820011 DOI: 10.3390/vetsci11010021] [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: 11/09/2023] [Revised: 12/17/2023] [Accepted: 12/22/2023] [Indexed: 01/23/2024] Open
Abstract
There is growing evidence by the literature that the unbalance between androgens and estrogens is a relevant condition associated with a common canine reproductive disorder known as cryptorchidism. The role of estrogens in regulating testicular cell function and reproductive events is supposedly due to the wide expression of two nuclear estrogen receptors (ERs), ER-alpha and ER-beta and a trans-membrane G protein-coupled estrogen receptor (GPER) in the testis. In this study, immunohistochemistry, Western blotting and qRT-PCR were used to assess the distribution and expression of GPER in the testis-epididymal complex in the normal and cryptorchid dog. ER-alpha and ER-beta were also evaluated to better characterize the relative abundances of all three receptors. In addition, in these tissues, the expression level of two proteins as SOD1 and Nrf2 normally associated with oxidative stress was investigated to evaluate a possible relationship with ERs. Our data revealed changes in the distribution and expression of the GPER between the normal and cryptorchid dog. In particular, dogs affected by cryptorchidism showed an upregulation of GPER at level of the examined reproductive tract. Also considering the obtained result of a modulation of SOD1 and Nrf2 expression, we could hypothesize the involvement of GPER in the cryptorchid condition. Further studies are, however, necessary to characterize the role of GPER and its specific signaling mechanisms.

[PMID: 38123000 DOI: 10.1016/j.reprotox.2023.108525] [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: 08/15/2023] [Revised: 12/10/2023] [Accepted: 12/14/2023] [Indexed: 12/23/2023]
Abstract
SP-Max herbal capsule formulation contains Withania somnifera, Asparagus recemosus, Mucuna pruriens, Chlorophytum arundinaceum, Ipomoea digitata, and Dioscorea bulbifera which are reported in the 'Ayurveda', an Indian Traditional System of medicine as aphrodisiacs. The present study focused on the effect of herbomineral formulation, SP-Max in the treatment of oligospermia. Oligospermia was induced in male Swiss Albino mice by a single intraperitoneal injection of busulfan at a dose of 45 mg/kg. SP-Max herbomineral formulation was given at various doses of 130, 270, and 390 mg/kg for 45 days. Treatment with SP-Max herbomineral formulation at 130, 270 and 390 mg/kg doses significantly improved the sperm count, sperm motility and viability (p < 0.001). SP-Max treatment at a dose of 390 mg/kg significantly prevented the loss of anti-oxidant enzymes in testicular cells. SP-Max prevented the reduction in the level of testosterone, luteinizing hormone, and follicle-stimulating hormone. Histological findings showed that SP-Max treatment prevented degeneration of spermatid, interstitial cells, and Sertoli cells of the testes and also improved epididymal sperm count. High dose of SP-Max treatment i.e 390 mg/kg found to be more effective. Results showed that SP-Max herbomineral formulation is an effective treatment option for oligospermia by decreasing free radical damage to the testes and improving the levels of reproductive hormones.

Abstract
Falafel is the most common Egyptian street food, and deep-frying palm oil is a commonly used for frying it. The main objective of this research was to evaluate the effect of deep-frying palm olein oil-fried street falafel on testes of Wistar rats. Twenty-one adult male Wistar rats were randomly divided into three equal groups and given treatment as follows: control group received only distilled water, fresh palm olein oil (FPO) group received FPO (1 ml/100 g BW/day) and deep-frying palm olein oil (DPO) group received DPO (1 ml/100 g BW/day) orally for 28 days. Serum level of testosterone, testicular tissue oxidative status, and sperm characteristics were determined. Testicular specimens were processed for histopathological examination. The results revealed that DPO group showed a significant (p<0.01) decrease in serum testosterone with significant (p<0.01) reduction of testicular glutathione, superoxide dismutase, and glutathione peroxidase, whereas testicular malondialdehyde was markedly (p<0.001) raised. There were significant decrease in epididymal sperm count (p<0.01), sperm progress motility (p<0.001), and increase abnormal sperm rate (p<0.001) in DPO group. Testicular histology in DPO group showed structural abnormalities which are compatible with lipid peroxidation and antioxidant deficiency. In Conclusion, deep-frying palm olein oil that used for the frying falafel induces testicular abnormalities in rats.

Abstract
BACKGROUND Out of all measure systemic exposure to fluorides can cause defect of skeletal and dental fluorosis. Endoplasmic reticulum (ER) stress is caused by fluorine-induced oxidative stress and importance of vitamin D in its prevention is not known enough in bone cells. This study was carried out to investigate fluorine-induced oxidative stress, ER stress, and death pathways and the effect of vitamin D on them. METHODS MC3T3-E1 mouse osteoblast cell line was used as the material of the study. The NaF and vitamin D concentrations were determined by the MTT assay. NaF treatments and vitamin D supplementation (pre-add, co-add, and post-add) was administered in the cell line at 24th and 48th hours. The expression of the genes in oxidative stress, ER stress, and death pathways was determined using RT-qPCR and Western blotting techniques. RESULTS Vitamin D significantly reduced mRNA expression levels of SOD2, CYGB, ATF6, PERK, IRE1, ATG5 and BECN1 whereas caused an increase in levels GPX1, SOD1, NOS2 and Caspase-3 in MC3T3-E1 mouse osteoblast cell line of NaF-induced. In addition, GPX1, SOD1, ATF6, PERK, IRE1, BECN1, Caspase-3 and RIPK1 protein levels were examined by Western blot analysis, and it was determined that vitamin D decreased IRE1 and PERK protein levels, but increased GPX1, SOD1, ATF6 and Caspase-3 protein levels. CONCLUSION The findings of the study suggest that vitamin D has protective potential against NaF-induced cytotoxicity reasonably through the attenuation of oxidative stress, ER stress, ATG5, IRE1 and by increasesing caspase-3 in vitro conditions.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2023; 901:165938. [PMID: 37541514 DOI: 10.1016/j.scitotenv.2023.165938] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/30/2023] [Revised: 07/23/2023] [Accepted: 07/29/2023] [Indexed: 08/06/2023]
Abstract
Polybrominated diphenyl ethers (PBDEs), a class of brominated flame retardants (BFRs), are employed in various manufactured products to prevent fires, slow down their spread and reduce the resulting damages. Decabromodiphenyl ether (BDE-209), an example of PBDEs, accounts for approximately 82 % of the total production of PBDEs. BDE-209 is a thyroid hormone (TH)-disrupting chemical owing to its structural similarity with TH. Currently, increase in the level of BDE-209 in biological samples has become a major issue because of its widespread use. BDE-209 causes male reproductive toxicity mainly via impairment of steroidogenesis, generation of oxidative stress (OS) and interference with germ cell dynamics. Further, exposure to this chemical can affect metabolic status, sperm concentration, epigenetic regulation of various developmental genes and integrity of blood-testis barrier in murine testis. However, the possible adverse effects of BDE-209 and its mechanism of action on the male reproductive health have not yet been critically evaluated. Hence, the present review article, with the help of available literature, aims to elucidate the reproductive toxicity of BDE-209 in relation to thyroid dysfunction in rodents. Further, several crucial pathways have been also highlighted in order to strengthen our knowledge on BDE-209-induced male reproductive toxicity. Data were extracted from scientific articles available in PubMed, Web of Science, and other databases. A thorough understanding of the risk assessment of BDE-209 exposure and mechanisms of its action is crucial for greater awareness of the potential threat of this BFR to preserve male fertility.

Abstract
Benzo(a)pyrene (BaP) is a substance with the potential to induce endocrine disruption in the F0 generation and cause adverse multigenerational effects (F1 generation) for reproductive parameters in rats. The objective of this study was to investigate the occurrence of transgenerational inheritance in the reproductive aspects of male and female rats belonging to the F2 generation (MF2). This investigation was conducted following the exposure of male rats from the F0 generation to BaP to assess potential effects on subsequent generation from the maternal lineage (F1). For that, juvenile male Wistar rats (F0) were orally exposed to BaP (0.1 µg/kg/day) for 31 consecutive days. In adulthood, they were mated with untreated females to obtain female offspring (F1), which later produced the MF2. In the MF2 generation, both males and females exhibited increased body weight on postnatal day (PND) 1. In MF2 males, we observed delayed preputial separation, altered pup weight, reduced levels of follicle-stimulating hormone (FSH), increased intratesticular testosterone levels, decreased type A sperm, epididymal disturbances, reduced 5 α-reductase activity, increased testicular proliferation, and alterations in testicular antioxidant enzymes. In MF2 females, we noted morphological uterine enlargement, reduced sexual activity, and decreased progesterone levels. The findings suggest that the alterations observed in both MF2 males and females can be attributed to modifications in the sperm from F0 generation, which were subsequently transmitted to F1 females and MF2 generation due to BaP exposure.

Abstract
Lipid oxidation by reactive oxygen species (ROS) provide several different oxidation products that have been implicated in inflammatory responses. Ground state atomic oxygen [O(3 P)] is produced by the photodeoxygenation of certain heterocyclic oxides and has a reactivity that is unique from other ROS. Due to the reactive nature of O(3 P), the site of O(3 P)-generation is expected to influence the products in heterogenous solutions or environments. In this work, the oxidation of low-density lipoprotein (LDL) by lipids with covalently bound O(3 P)-photoprecursors was compared to more hydrophilic O(3 P)-photoprecursors. Lipid oxidation products were quantified after Bligh-Dyer extraction and pentafluorobenzyl bromide (PFB) derivatization by GC-MS. Unlike the more hydrophilic O(3 P)-photoprecursors, the oxidation of LDL during the irradiation of lipid-(O3 P)-photoprecursor conjugates showed little quenching by the addition of the O(3 P)-scavenging sodium allyl sulfonate. This indicated that lipophilic O(3 P)-photoprecursors are expected to generate lipid oxidation products where other more hydrophilic O(3 P)-photoprecursors could be quenched by other reactive groups present in solution or the environment.

Abstract
Antioxidant actions of melatonin and its impact on testicular function and fertility have already been described. Considering that Sertoli cells contribute to provide structural support and nutrition to germ cells, we evaluated the effect of melatonin on oxidative state and lactate metabolism in the immature murine TM4 cell line and in immature hamster Sertoli cells. A prooxidant stimulus applied to rodent Sertoli cells expressing MT1/MT2 receptors, increased lipid peroxidation whereas decreased antioxidant enzymes (superoxide dismutase 1, catalase, peroxiredoxin 1) expression and catalase activity. These changes were prevented by melatonin. Furthermore, melatonin stimulated lactate dehydrogenase (LDH) expression/activity via melatonin receptors, and increased intracellular lactate production in rodent Sertoli cells. Interestingly, oral melatonin supplementation in infertile men positively regulated LDHA testicular mRNA expression. Overall, our work provides insights into the potential benefits of melatonin on Sertoli cells contributing to testicular development and the future establishment of a sustainable spermatogenesis.

Abstract
Inflammasomes are multi-protein complexes localized within immune and non-immune cells that induce caspase activation, proinflammatory cytokine secretion, and ultimately pyroptosis-a type of cell death. Inflammasomes are involved in a variety of human diseases, especially acute or chronic inflammatory diseases. In this review, we focused on the strong correlation between the NLRP3 inflammasome and various reproductive diseases, including ovarian aging or premature ovarian insufficiency, PCOS, endometriosis, recurrent spontaneous abortion, preterm labor, pre-eclampsia, and male subfertility, as well as the multifaceted role of NLRP3 in the pathogenesis and treatment of these diseases. In addition, we provide an overview of the structure and amplification of inflammasomes. This comprehensive review demonstrates the vital role of NLRP3 inflammasome activation in human reproductive diseases together with the underlying mechanisms, offers new insights for mechanistic studies of reproduction, and provides promising possibilities for the development of drugs targeting the NLRP3 inflammasome for the treatment of reproductive disorders in the future.

Abstract
Integrated approaches to testing and assessments (IATAs) have been proposed as a method to organise new approach methodologies in order to replace traditional animal testing for chemical safety assessments. To capture the mechanistic aspects of toxicity assessments, IATAs can be framed around the adverse outcome pathway (AOP) concept. To utilise AOPs fully in this context, a sufficient number of pathways need to be present to develop fit for purpose IATAs. In silico approaches can support IATA through the provision of predictive models and also through data integration to derive conclusions using a weight-of-evidence approach. To examine the maturity of a developmental and reproductive toxicity (DART) AOP network derived from the literature, an assessment of its coverage was performed against a novel toxicity dataset. A dataset of diverse compounds, with data from studies performed according to OECD test guidelines TG-421 and TG-422, was curated to test the performance of an in silico model based on the AOP network - allowing for the identification of knowledge gaps within the network. One such gap in the knowledge was filled through the development of an AOP stemming from the molecular initiating event 'glutathione reaction with an electrophile' leading to male fertility toxicity. The creation of the AOP provided the mechanistic rationale for the curation of pre-existing structural alerts to relevant key events. Integrating this new knowledge and associated alerts into the DART AOP network will improve its coverage of DART-relevant chemical space. In addition, broadening the coverage of AOPs for a particular regulatory endpoint may facilitate the development of, and confidence in, robust IATAs.

Abstract
Oxidative stress can be induced in the testes by a wide range of factors, including scrotal hyperthermia, varicocele, environmental toxicants, obesity and infection. The clinical consequences of such stress include the induction of genetic damage in the male germ line which may, in turn, have serious implications for the health and wellbeing of the progeny. In order to confirm the transgenerational impact of oxidative stress in the testes, we sought to develop an animal model in which this process could be analysed. Our primary approach to this problem was to induce Sertoli cells (robust, terminally differentiated, tissue-specific testicular cells whose radioresistance indicates significant resistance to oxidative stress) to generate high levels of reactive oxygen species (ROS) within the testes. To achieve this aim, six follicle-stimulating hormone (FSH) peptides were developed and compared for selective targeting to Sertoli cells both in vitro and in vivo. Menadione, a redox-cycling agent, was then conjugated to the most promising FSH candidate using a linker that had been optimised to enable maximum production of ROS in the targeted cells. A TM4 Sertoli cell line co-incubated with the FSH-menadione conjugate in vitro exhibited significantly higher levels of mitochondrial ROS generation (10-fold), lipid peroxidation (2-fold) and oxidative DNA damage (2-fold) than the vehicle control. Additionally, in a proof-of-concept study, ten weeks after a single injection of the FSH-menadione conjugate in vivo, injected male mice were found to exhibit a 1.6 fold increase in DNA double strand breaks and 13-fold increase in oxidative DNA damage to their spermatozoa while still retaining their ability to initiate a pregnancy. We suggest this model could now be used to study the influence of chronic oxidative stress on testicular function with emphasis on the impact of DNA damage in the male germ line on the mutational profile and health of future generations.

[PMID: 37545847 PMCID: PMC10403685 DOI: 10.1016/j.euros.2023.06.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 06/12/2023] [Indexed: 08/08/2023] Open
Abstract
Background The primary microenvironment of the testis comprises testicular interstitial fluid (TIF) surrounding the seminiferous tubules and testicular interstitial tissue. The pathological alterations of germ and Sertoli cells could affect the TIF composition and might contain putative biomarkers for monitoring active spermatogenesis. Objective We identified differentially expressed proteins in the TIF of patients with obstructive (OA) or nonobstructive (NOA) azoospermia to elucidate the underlying etiology of defective spermatogenesis. Design setting and participants We prospectively enrolled nine patients, including three men with OA and six with NOA with (n = 3) and without (n = 3) successful sperm retrieval. Their TIF was collected during the testicular sperm extraction procedure. Outcome measurements and statistical analysis TIF was analyzed using liquid chromatography-tandem mass spectrometry to identify differentially expressed proteins specific to OA and NOA with or without successful sperm retrieval. The dysregulated protein was further validated using Western blotting. Results and limitations Among the 555 TIF proteins identified in NOA patients, 14 were downregulated relative to OA patients. These proteins participate in biological processes such as proteolysis, complement activation, and immune responses; complement and coagulation cascade pathways were also enriched. Furthermore, 68 proteins with significantly higher levels were identified in the TIF of NOA patients with successful sperm retrieval than in those with failed sperm retrieval; these are mainly implicated in oxidation-reduction processes. The expression of calreticulin, which can distinguish successful and failed testicular sperm retrieval in the NOA group, was validated by Western blotting. Conclusions We provide the first scientific evaluation of TIF protein composition in men with azoospermia. These findings will help identify the physiological and pathological roles of each protein in regulating sperm production. Thus, our study underscores the potential of TIF in sperm retrieval biomarker discovery and would serve as a foundation for further studies to improve treatment strategies against azoospermia. Patient summary Using a proteomic approach, we identified and analyzed the total protein content of testicular interstitial fluid in humans with defective spermatogenesis for the first time and discovered altered protein expression patterns in patients with nonobstructive azoospermia (NOA). Proteins related to oxidation-reduction processes were upregulated in NOA patients with successful sperm retrieval compared with those with failed sperm retrieval. This can aid the development of novel diagnostic tools for successful testicular sperm retrieval.

Abstract
We investigated the impact of Coartem™ (COA) and aflatoxin B1 (AFB1) on rats' hypothalamus, epididymis, and testis. Male rats were randomly grouped (n = 5 rats) and treated: control group (corn oil), AFB1 (70 µg/kg), COA (5 mg/kg), COA + AFB1 (5 + 0.035 mg/kg) and COA + AFB1 (5 + 0.07 mg/kg) for 28 days. Blood samples were collected for serum prolactin, testosterone, follicle-stimulating and luteinising hormones (FSH and LH) assay upon sacrifice. The semen, hypothalamus, epididymis, and testes were harvested for morphological, biochemical, and histopathology determination of oxidative, inflammation stress, genomic integrity, and pathological alterations. Exposure to the COA and AFB1 caused the cauda epididymal spermatozoa to display low motility, viability, and volume, with increased abnormalities. Hormonal disruption ensued in animals exposed to COA and AFB1 alone or together, exemplified by increased prolactin, and decreased testosterone, FSH and LH levels. Treatment-related reduction in biomarkers of testicular metabolism-acid and alkaline phosphatases, glucose-6-phosphate dehydrogenase, and lactate dehydrogenase-were observed. Also, COA and AFB1 treatment caused reductions in antioxidant (Glutathione and total thiols) levels and antioxidant enzyme (Catalase, superoxide dismutase, glutathione peroxidase, and glutathione-S-transferase) activities in the examined organs. At the same time, treatment-related increases in DNA damage (p53), oxidative stress (xanthine oxidase, reactive oxygen and nitrogen species and lipid peroxidation), inflammation (nitric oxide and tumour necrosis factor-alpha), and apoptosis (caspase-9, and -3) were observed. Chronic exposure to COA and AFB1 led to oxidative stress, inflammation, and DNA damage in male rats' hypothalamic-reproductive axis, which might potentiate infertility if not contained.

Punica granatum (Pomegranate) Peel Extract Pre-Treatment Alleviates Fenpropathrin-Induced Testicular Injury via Suppression of Oxidative Stress and Inflammation in Adult Male Rats. TOXICS 2023; 11:504. [PMID: 37368604 DOI: 10.3390/toxics11060504] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/25/2023] [Revised: 05/26/2023] [Accepted: 05/30/2023] [Indexed: 06/29/2023]
Abstract
Fenpropathrin (FNP) is one of the commonly used insecticides in agriculture and domestically, leading to environmental and health problems. The goal of the current investigation was to determine how well pomegranate peel extract (PGPE) could prevent the testicular toxicity and oxidative stress induced by FNP. Four groups of male Wistar rats were randomly assigned: negative control (corn oil), PGPE (500 mg/kg BW), positive control (FNP; 15 mg/kg BW, 1/15 LD50), and PGPE + FNP. For four weeks, the rats received their doses daily and orally via gavage. The major phytochemical components (total phenolic, flavonoids, and tannins contents) detected in PGPE by GC-MS included ellagic acid, hydroxymethylfurfurole, guanosine, and pyrogallol with high total phenolic, flavonoids, and tannin contents. FNP-treated rats showed a marked elevation in testicular levels of thiobarbituric acid-reactive substances, hydrogen peroxide, and protein carbonyl content, as well as the activity of aminotransferases and phosphatases. Meanwhile. a significant decline in body weight, gonadosomatic index, glutathione, protein contents, enzymatic antioxidants, and hydroxysteroid dehydrogenase (3β HSD, and 17β HSD) activity was observed. In addition, significant alterations in testicular P53, Cas-3, Bcl-2, IL-β, IL-10, testosterone, follicle-stimulating and luteinizing hormones, and sperm quality were detected. Furthermore, biochemical and molecular changes were corroborated testicular histological abnormalities. Moreover, PGPE-pretreated FNP-intoxicated rats demonstrated considerable improvement in the majority of the studied parameters, when compared to FNP-treated groups. Conclusively, PGPE provided a potent protective effect against the testicular toxicity caused by FNP, due to its antioxidant-active components.

Abstract
This study aimed to evaluate the gold nanoparticles (AuNPs) animal sterilizing potential after intratesticular injections and long-term adverse reproductive and systemic effects. Adult male Wistar rats were divided into control and gold nanoparticle (AuNPs) groups. The rats received 200µL of saline or AuNPs solution (16µg/mL) on experimental days 1 and 7 (ED1 and ED7). After 150 days, the testicular blood flow was measured, and the rats were mated with females. After mating, male animals were euthanized for histological, cellular, and molecular evaluations. The female fertility indices and fetal development were also recorded. The results indicated increased blood flow in the testes of treated animals. Testes from treated rats had histological abnormalities, shorter seminiferous epithelia, and oxidative stress. Although the sperm concentration was lower in the AuNP-treated rats, there were no alterations in sperm morphology. Animals exposed to AuNPs had decreased male fertility indices, and their offspring had lighter and less efficient placentas. Additionally, the anogenital distance was longer in female fetuses. There were no changes in the histology of the kidney and liver, the lipid profile, and the serum levels of LH, testosterone, AST, ALT, ALP, albumin, and creatinine. The primary systemic effect was an increase in MDA levels in the liver and kidney, with only the liver experiencing an increase in CAT activity. In conclusion, AuNPs have a long-term impact on reproduction with very slight alterations in animal health. The development of reproductive biotechnologies that eliminate germ cells or treat local cancers can benefit from using AuNPs.

Abstract
Iron is an essential micronutrient for human biology and health, but high iron levels can be dangerous. Both iron deficiency and iron overload have been linked to reproductive health. This review summarizes the effects of iron deficiency and iron overload on men of reproductive age, women of reproductive age, and pregnant women. In addition, appropriate iron levels and the need for iron and nutritional supplements at different stages of life and pregnancy are discussed. In general, men should be aware of the risk of iron overload at any stage of life; women should take appropriate iron supplements before menopause; postmenopausal women should pay attention to the risk of iron overload; and pregnant women should receive reasonable iron supplementation in middle and late pregnancy. By summarizing evidence on the relationship between iron and reproductive health, this review aims to promote the development of strategies to optimize reproductive capacity from the perspective of nutrition. However, additional detailed experimental investigations and clinical studies are needed to assess the underlying causes and mechanisms of the observed associations between iron and reproductive health.

Abstract
Herein, we compare the different experimental regimes used to induce testicular heat stress and summarise their impact on sperm production and male fertility. Irrespective of the protocol used, scrotal heat stress causes loss of sperm production. This is first seen 1-2 weeks post heat stress, peaking 4-5 weeks thereafter. The higher the temperature, or the longer the duration of heat, the more pronounced germ cell loss becomes, within extreme cases this leads to azoospermia. The second, and often underappreciated impact of testicular hyperthermia is the production of poor-quality spermatozoa. Typically, those cells that survive hyperthermia develop into morphologically abnormal and poorly motile spermatozoa. While both apoptotic and non-apoptotic pathways are known to contribute to hyperthermic germ cell loss, the mechanisms leading to formation of poor-quality sperm remain unclear. Mechanistically, it is unlikely that testicular hyperthermia affects messenger RNA (mRNA) abundance, as a comparison of four different mammalian studies shows no consistent single gene changes. Using available evidence, we propose two novel models to explain how testicular hyperthermia impairs sperm formation. Our first model suggests aberrant alternative splicing, while the second model proposes a loss of RNA repression. Importantly, neither model requires consistent changes in RNA species.

Abstract
Amorphous silica nanoparticles (SiNPs) are being utilized in different fields such as medicine, cosmetics, and foods. However, the causes and mechanisms underlying SiNP testicular damage remain largely unclear. In the present study, we aimed to investigate this issue. Thirty male rats were randomly divided into three groups: control group (n = 10), 500 ppm SiNP-treated group (n = 10), and 1000 ppm SiNP-treated group (n = 10). SiNPs were given orally in drinking water for 30 days. Micronucleus assay was performed on blood RBCs. The concentrations of testicular malondialdehyde (MDA) and glutathione (GSH) and catalase (CAT) activity were measured. Moreover, the histopathological alterations and the expression of apoptotic (caspase-3) and pro-inflammatory and oxidative stress markers (iNOS) in testes and epididymis were analyzed and compared between the three groups. The results showed an increased level of micronucleus frequencies in the 1000 ppm-treated group, as well as increased levels of MDA and decreased activity of CAT and GSH content in testicular tissues in the 1000 ppm-treated group, suggesting DNA damage and oxidative stress mechanisms. Also, there were significant testicular histopathological alterations in this group. Furthermore, 1000-ppm SiNPs could enhance testicular apoptosis, inflammation, and oxidative stress by increasing the expression of apoptotic, pro-inflammatory, and oxidative stress genes including caspase 3 and iNOS in the examined tissue. The lower concentration of SiNPs did not produce any significant biochemical, histopathological, or immunohistochemical alterations whereas 1000-ppm SiNPs resulted in significant testicular changes by exacerbating apoptotic, inflammatory, and oxidative stress-mediated testicular damage.

Abstract
Oxidative stress is the result of an imbalance between the formation of reactive oxygen species (ROS) and the levels of enzymatic and non-enzymatic antioxidants. The assessment of biological redox status is performed by the use of oxidative stress biomarkers. An oxidative stress biomarker is defined as any physical structure or process or chemical compound that can be assessed in a living being (in vivo) or in solid or fluid parts thereof (in vitro), the determination of which is a reproducible and reliable indicator of oxidative stress. The use of oxidative stress biomarkers allows early identification of the risk of developing diseases associated with this process and also opens up possibilities for new treatments. At the end of the last century, interest in oxidative stress biomarkers began to grow, due to evidence of the association between the generation of free radicals and various pathologies. Up to now, a significant number of studies have been carried out to identify and apply different oxidative stress biomarkers in clinical practice. Among the most important oxidative stress biomarkers, it can be mentioned the products of oxidative modifications of lipids, proteins, nucleic acids, and uric acid as well as the measurement of the total antioxidant capacity of fluids in the human body. In this review, we aim to present recent advances and current knowledge on the main biomarkers of oxidative stress, including the discovery of new biomarkers, with emphasis on the various reproductive complications associated with variations in oxidative stress levels.

Abstract
The effect of fluted pumpkin seeds (FPS) consumption on the antioxidant status of the testes of aged Wistar rats was evaluated in this study. Sixty (50 aged, 6 months old, and 10 young, 2 months old) rats were divided into six groups of 10 per each group. Testosterone (15 mg kg-1 body weight, once weekly for 40 days) was injected intraperitoneally and used as positive control. FPS intake (50, 100, and 200 mg kg-1 body weight) or vehicle control (corn oil) were administered orally, twice weekly for 40 days and compared with the untreated aged and young control rats. Changes in antioxidant status in the testis of the aged rats was reflected as increased superoxide dismutase and catalase activities and glutathione and decreased lipid peroxidation levels which were attenuated more efficiently by the lowest dose FPS (50 mg kg-1 body weight). Additionally, nitrite concentration that was found to be diminished in the aged rats was raised to the young control values after intake of the FPS (50 mg kg-1 body weight). As expected, testosterone injection increased endogenous testosterone concentration and also remained higher in the untreated aged animals than in young control and treated aged rats. In conclusion, compromised antioxidant defense system of the testes that is associated with ageing could be reversed to the status of the young control by the intake of FPS.

Abstract
Perfluorooctanesulfonate acid (PFOS) is a typical persistent organic pollutant that widely exists in the environment. To clarify the toxic effects and mechanisms of PFOS and to find effective intervention strategies have been attracted global attention. Here, we investigated the effects of PFOS on the male reproductive system and explored the potential protective role of 1α,25-dihydroxyvitamin D3 (1α,25(OH)2 D3 ). Our results showed that 1α,25(OH)2 D3 intervention significantly improved PFOS-induced sperm quality decline and testicular damage. Moreover, 1α,25(OH)2 D3 aggrandized the total antioxidant capacity. Furthermore, after PFOS exposure, the transcription factor nuclear factor erythroid-related factor 2 (Nrf2) was adaptively increased together with its target genes, such as HO-1, NQO1, and SOD2. Meanwhile, 1α,25(OH)2 D3 ameliorated PFOS-induced augment of Nrf2 and target genes. These findings indicated that 1α,25(OH)2 D3 might attenuate PFOS-induced reproductive injury in male mice via Nrf2-mediated oxidative stress.

Braun BC, Müller K. Role of glyoxalase I and II in somatic and spermatogenic testicular cells during the postnatal development of the domestic cat. Theriogenology 2023; 197:10-15. [PMID: 36462331 DOI: 10.1016/j.theriogenology.2022.11.028] [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: 09/14/2022] [Revised: 11/21/2022] [Accepted: 11/21/2022] [Indexed: 11/27/2022]
Abstract
Like humans, many felid species suffer from teratozoospermia and frequently produce low numbers of normal spermatozoa. Male fertility can be affected by oxidative and dicarbonyl stress. Because of the high level of glycolytic activity in testes, reactive dicarbonyl metabolites may arise as side-products of glycolysis; their generation is further promoted by oxidative stress. Alpha-oxoaldehydes, including methylglyoxal (MG), are reactive dicarbonyl metabolites and substrates for the formation of advanced glycation end products. Elevated levels of both may lead to dicarbonyl stress and cause cellular dysfunction. However, MG and other α-oxoaldehydes can be converted to less dangerous molecules via the glyoxalase pathway. In this pathway, α-oxoaldehydes react with glutathione (GSH), forming a thioacetal, which becomes metabolized by glyoxalase I (GLO I) to S-D-lactoyl-glutathione (SLG). Glyoxalase II (GLO II) converts SLG to d-lactate upon the release of GSH. Nothing is known about the glyoxalase system in the feline testis and its capacity to mitigate an excess of dicarbonyl metabolites. To study whether GLO I and GLO II are present and have a specific function in the testis of the domestic cat, the gene expression of both enzymes were analyzed in testis samples of different developmental stages (prepubertal, pubertal, postpubertal). Furthermore, the presence of GLO I and GLO II proteins was investigated via immunohistochemistry. The GLO I gene expression does not change between developmental stages. Immunohistochemistry revealed strong signals for GLO I in the cytoplasm and nuclei of Sertoli and Leydig cells during all developmental stages. GLO I was described as catalyzing the rate-limiting step in the glyoxalase pathway. This implies a function on the part of this enzyme of sustaining the homeostasis of somatic testicular cells. For GLO II, we observed stage-dependent mRNA expression, which was significantly increased after puberty. In accordance with this observation, clear immunohistochemical GLO II signals were observed in nuclei of individual germ cells. The most intense signals were visible in spermatocytes. The different localizations of the strong GLO I and GLO II signals indicate that GLO II, in addition to the classical glyoxalase pathway, may have additional functions in meiotic germ cells, for example, providing lactate as an energy substrate and/or GSH as an antioxidant. Moreover, protein functions may be modulated via S-glutathionylation.

Abstract
Liver and muscle health are intimately connected. Nutritional strategies that support liver detoxification are beneficial to muscle recovery. Computational-in silico-molecular systems' biology analysis of supplementation of calcium and potassium glucarate salts and their metabolite D-glucaric acid (GA) reveals their positive effect on mitigation of liver detoxification via four specific molecular pathways: (1) ROS production, (2) deconjugation, (3) apoptosis of hepatocytes, and (4) β-glucuronidase synthesis. GA improves liver detoxification by downregulating hepatocyte apoptosis, reducing glucuronide deconjugates levels, reducing ROS production, and inhibiting β-Glucuronidase enzyme that reduces re-absorption of toxins in hepatocytes. Results from this in silico study provide an integrative molecular mechanistic systems explanation for the mitigation of liver toxicity by GA.

Abstract
BACKGROUND Paclitaxel is a widely used drug for the treatment of cancer, but it possesses toxic effects on male reproductive system. Administering paclitaxel with an antioxidant has become a strategy for preventing the side effects of paclitaxel. Although curcumin is an antioxidant, data concerning the effect of curcumin on paclitaxel-induced testis tissue are lacking. The present study was established to examine the protective impact of curcumin against testicular damage induced by paclitaxel. METHODS In the study, 40 Wistar albino male rats were used and randomly divided into 4 groups (n:10). The control group received only saline solution; the curcumin group received curcumin throughout the experiment; the paclitaxel group received a total of four doses of paclitaxel on days 1, 7, 14, and 21 of the experiment; curcumin + paclitaxel group received curcumin throughout the experiment and a total of four doses of paclitaxel on days 1, 7, 14, and 21 of the experiment. At the end of the experiment, the rats were decapitated under xylazine and ketamine anesthesia and their testicles were removed. The sections obtained from the testicles were stained with Hematoxylin & Eosin and histopathological damage was evaluated. The TUNEL method was applied to determine apoptotic cells. Testosterone levels were measured in the blood serum. The Johnsen testicular biopsy score (JTBS) was used to evaluate testicular tubules. DNA damage was evaluated in sperm samples taken from the ductus epididymis using the comet assay technique. RESULTS Testicular tissue was severely damaged in the paclitaxel group. In the curcumin + paclitaxel group, it was determined that the administration of curcumin with paclitaxel reduced the histological damage in the testicular tissue. Moreover, according to the JTBS, the value was significantly higher in the testicular tubules (p < 0.05). Testosterone levels were higher in curcumin + paclitaxel group than in paclitaxel group. DNA damage also decreased significantly in curcumin + paclitaxel group when compared to paclitaxel group (p < 0.05). DISCUSSION The results showed that curcumin may be protective against damage caused by paclitaxel in the testicles of rats.

ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2023; 30:42339-42350.

Abstract
Polycarbonate plastics for packaging and epoxy resins are both made with the industrial chemical bisphenol A (BPA). This investigation looked at the histological structure, antioxidant enzymes, and albino rats' testis to determine how coenzyme Q10 (CoQ10) impacts BPA toxicity. For the experiments, three sets of 18 male adult rats were created: group 1 received no therapy, group 2 acquired BPA, and group 3 got the daily BPA treatment accompanied by coenzyme Q10, 1 h apart. The experimental period ran for 14 days. The biochemical biomarkers catalase (CAT), superoxide dismutase (SOD), and malondialdehyde (MDA) were altered as a result of BPA exposure. The testicular histological architecture, which is made up of apoptosis, was also exaggerated. Furthermore, rats given BPA and CoQ10 treatment may experience a diminution in these negative BPA effects. These protective properties of CoQ10 may be correlated with the ability to eliminate oxidizing substances that can harm living species. The outcomes might support the hypothesis that CoQ10 prevented oxidative damage and boosted rats' stress responses when BPA was introduced. Thus, by shielding mammals from oxidative stress, CoQ10 aids in the growth and development of the animals. BPA is extremely hazardous to humans and can persist in tissues. Human reproductive functions are a worry due to human exposure to BPA, especially for occupational workers who are typically exposed to higher doses of BPA. As a result, in order to reduce the health risks, BPA usage must be minimized across a diverse range of industries, and improper plastic container handling must be prohibited. By giving CoQ10 to patients, BPA's harmful effects on reproductive structures and functions may be avoided.

Basic Clin Androl 2023; 33:1. [PMID: 36604652 PMCID: PMC9817316 DOI: 10.1186/s12610-022-00174-8] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2022] [Accepted: 10/24/2022] [Indexed: 01/07/2023] Open
Abstract
BACKGROUND Bisphenol A (BPA) is one of the most widely used synthetic chemicals worldwide. BPA as an endocrine disruptor affects the reproductive systems through estrogenic and antiandrogenic proprieties. Resveratrol (RES) as a natural polyphenol and potent antioxidant exhibits protective effects against reproductive toxicity by inhibiting of oxidative stress. 48 male rats were divided into eight groups (n=6), including CONTROL, OLIVE OIL (0.5 ml/ day), Carboxy methylcellulose (CMC) (1 ml of 10 g/l), RES (100mg/kg/day), low dose of BPA (25 mg/kg/day), high dose of BPA (50 mg/kg/day), low dose of BPA + RES, and high dose of BPA + RES. All treatments were done orally per day for 56 days. At the end of the 8th week, blood samples were collected for hormone assays. Then, the sperm parameters were analyzed, and the left testis was removed for stereological study. RESULTS We showed a significant decrease in sperm parameters in the low and high doses of BPA groups compared to control groups (P<0.05). The volume of testicular components as well as the diameter and length of seminiferous tubules significantly reduced (11-64 %), and the total number of the testicular cell types decreased (34-67 %) on average in the low and high doses of BPA groups. Moreover, serum follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone hormones concentration showed a significant reduction in both doses of BPA groups (P<0.01). Nonetheless, treatment with RES could ameliorate all the above-mentioned changes in the low and high doses of BPA groups (P<0.05). CONCLUSIONS RES could prevent BPA-induced testicular structural changes and sperm quality via improving gonadotropin hormones and testosterone levels.

Abstract
Ferroptosis, an iron-dependent type of regulated cell death, is triggered by the accumulation of lethal lipid peroxides. Due to its potential in exploring disease progression and highly targeted therapies, it is still a widely discussed topic nowadays. In recent studies, it was found that ferroptosis was induced when testicular tissue was exposed to some high-risk factors, such as cadmium (Cd), busulfan, and smoking accompanied by a variety of reproductive damage characteristics, including changes in the specific morphology and ferroptosis-related features. In this literature-based review, we summarize the related mechanisms of ferroptosis and elaborate upon its relationship network in the male reproductive system in terms of three significant events: the abnormal iron metabolism, dysregulation of the Cyst(e)ine/GSH/GPX4 axis, and lipid peroxidation. It is meaningful to deeply explore the relationship between ferroptosis and the male reproductive system, which may provide suggestions regarding pristine therapeutic targets and novel drugs.

Abstract
The present study was designed to evaluate the protective effect of fluted pumpkin seeds (FPS) against caffeine (CAFF) induced testicular toxicity in rats. Thirty young healthy male Wistar rats (196 ± 12 g) were randomly organized into five sets of six animals per each group: control, caffeine (CAFF; 50 mg kg-1 bw) and FPS co-treatment groups (CAFF + 50 mg FPS, CAFF + 100 mg FPS and CAFF + 200 mg FPS kg-1 bw). CAFF and FPS were administered daily and twice per week respectively by oral gavage for 40 days. CAFF treatment decreased testicular lactate dehydrogenase enzyme activity level, which was attenuated on co-administration with FPS at 50 and 100 mg kg-1 bw. Furthermore, CAFF decreased seminiferous epithelia thickness and spermatogenesis score index and increased the number of tubules with abnormal histological features, which were attenuated on co-administration with FPS at 50 mg kg-1 bw much more than at the higher doses (p < 0.05). CAFF did not affect malondialdehyde and glutathione concentrations and glutathione peroxidase (GSH-Px) activity in the testes whereas FPS co-treatment at the higher doses elevated glutathione level and GSH-Px activity and did not affect spermatogenesis score index at the highest dose (200 mg kg-1 bw). Testicular malondialdehyde concentrations remained unaffected in all FPS co-treatment groups. Overall, FPS is able to minimize the CAFF-induced testicular injury at lower than at the higher tested doses.

Abstract
Bisphenol A (BPA), a commonly used plasticizer in the production of polycarbonate plastics and epoxy resins, has been shown to induce male reproductive toxicity. However, the effects of BPA exposure on early testicular development have not been thoroughly studied, and the underlying mechanism is yet to be elucidated. In the current study, neonatal male mice were exposed to BPA at 0, 0.1, and 5 mg/kg, respectively, by daily subcutaneous injection during postnatal day (PND) 1-35 to explore its effects on testicular development at PND 36 (the end of the first round of spermatogenesis). Morphological analyses showed that BPA exposure significantly induced apoptosis of testicular cells (p < 0.01 and p < 0.001) and reduced the thickness of seminiferous epithelium (p < 0.01). In addition, BPA exposure significantly decreased the total antioxidant capacity of testes and levels of transcription factor Nrf2 as well as its downstream antioxidant molecules of NQO1 and GPx-1 (p < 0.05 and p < 0.01). Furthermore, global m6A modifications of mRNAs were upregulated accompanied by declined m6A demethylase (FTO) in the testes of BPA groups (p < 0.05 and p < 0.01). MeRIP-quantitative real-time polymerase chain reaction (qPCR) demonstrated that BPA exposure markedly increased the m6A modification of Nrf2 mRNA (p < 0.05 and p < 0.01). These findings suggest that upregulation of m6A induced by inhibited FTO may be involved in BPA-induced testicular oxidative stress and developmental injury during postnatal development, which provides a new idea to reveal the mechanism underlying BPA interfering with testicular development.

Abstract
The potential reproductive toxic effects of oral TiO2 NPs in adult male rats as well as the possible alleviation of chitosan administration was investigated. Animals were allocated to four groups; the first group received deionized water and was assigned as a control group. In the second group, rats received chitosan at a dose of 5 mg/kg BW/day. The third group was designed for administration of TiO2 NPs at a dose of 150 mg/kg BW/day (1/80 LD50). Rats in the fourth group received both TiO2 NPs and chitosan. After 14 days, TiO2 NPs induced testicular lipid peroxidation as well as oxidative stress. Nano-titanium significantly upregulated genes that encode apoptosis and inflammation in testicular tissue. Moreover, it induced histological alteration in the testicular structure with impairment in spermatogenesis via reduction of PCNA immune-staining. Chitosan administration significantly improved the activities of testicular GPx, SOD, and CAT enzymes. In addition, it significantly down-regulated the relative expressions of pro-apoptotic and pro-inflammatory testicular genes. Chitosan was able to improve the testicular architecture as well as spermatogenesis. The current study revealed the capability of chitosan to ameliorate nano-titanium induced testicular toxicity. Thus, attention should be given to the extensive consumption of nano-titanium particles.

Abstract
This review is aimed at illustrating and discussing the neuroimmune endocrinological aspects of the SARS-CoV-2 infection in light of the studies on this topic that have so far appeared in the literature. The most characteristic findings and pending controversies were derived by PubMed and Scopus databases. We included original and observational studies, reviews, meta-analysis, and case reports. The entry of the coronavirus into susceptible cells is allowed by the interaction with an ecto-enzyme located on human cells, the angiotensin-converting enzyme 2 (ACE2). SARS-CoV-2 also targets the central nervous system (CNS), including hypothalamic-pituitary structures, as their tissues express ACE2, and ACE2 mRNA expression in hypothalamus and pituitary gland cells has been confirmed in an autoptic study on patients who died of COVID 19. SARS-CoV-2 infection may cause central endocrine disorders in acute phase and in post-COVID period, particularly due to the effects of this virus at CNS level involving the hypothalamic-pituitary axis. The aggression to the hypothalamus-pituitary region may also elicit an autoimmune process involving this axis, responsible consequently for functional disorders of the satellite glands. Adrenal, thyroid and gonadal dysfunctions, as well as pituitary alterations involving GH and prolactin secretions, have so far been reported. However, the extent to which COVID-19 contributes to short- and long-term effects of infection to the endocrine system is currently being discussed and deserves further detailed research.

[PMID: 35973585 DOI: 10.1016/j.ygcen.2022.114104] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/23/2022] [Revised: 08/05/2022] [Accepted: 08/11/2022] [Indexed: 11/18/2022]
Abstract
High-fat diet (HFD) affects the physiology of reproduction in males, and many studies have investigated its detrimental effects. In this study, we investigated the cellular response induced by an HFD in the rat testis, focusing on the mitochondrial compartment. After five weeks of HFD, an increase in the levels of malondialdehyde and of reduced form of glutathione in the rat testis indicated an increase in lipid peroxidation. The results showed an increase in autophagy, apoptosis, and mitochondrial damage in the testis of HFD rats. We found a decrease in the protein expression of mitochondrial antioxidant enzymes, such as catalase and SOD2. Immunohistochemical analysis revealed a decrease in the immunofluorescent signal of SOD2, mainly in the spermatogonia and spermatocytes of HFD rats. HFD-induced mitochondrial damage caused a reduction in mitochondria, as evidenced by a decrease in the protein expression of TOM20, a mitochondrial outer membrane receptor. Consistently, HFD enhanced the levels of the PINK1 protein, a mitophagy marker, suggesting the removal of damaged mitochondria under these conditions. Induction of mtDNA damage and repair was stronger in the HFD rat testis. Finally, we found a decrease in the mtDNA copy number and expression of the POLG enzyme, which is involved in mtDNA replication. In conclusion, our results showed that autophagy and apoptosis are activated in the testis of HFD rats as a survival strategy to cope with oxidative stress. Furthermore, HFD-induced oxidative stress affects the mitochondria, inducing mtDNA damage and mtDNA copy number reduction. Mitophagy and mtDNA repair mechanisms might represent a mitochondrial adaptive response.

Vet World 2022; 15:2525-2534. [PMID: 36590130 PMCID: PMC9798052 DOI: 10.14202/vetworld.2022.2525-2534] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2022] [Accepted: 09/23/2022] [Indexed: 11/11/2022] Open
Abstract
Background and Aim Human exposure to aluminum is inevitable, and one of the most adverse health effects of aluminum is a decrease in male fertility rates. Therefore, this study investigated the ameliorative effects of an aqueous extract from Laurus nobilis-bay leaf (BL) on aluminum chloride (AlCl3)-induced testicular toxicity in rats. Materials and Methods Twenty-four Wistar rats were divided into four groups (n = 6, each group): The control (group 1) received normal saline; Group 2 animals were intraperitoneally administered with 30 mg/kg body weight (BW) AlCl3; and Groups 3 and 4 were co-administered AlCl3 with 125 or 250 mg/kg BW of BL extract, respectively, for 21 days. Testes, epididymis, and blood samples were collected. Testicular plasma enzyme activity was measured using a spectrophotometric assay, while concentrations of inflammatory biomarkers were determined using enzyme-linked immunosorbent assay kits. Results There was a significant increase (p < 0.05) in testicular enzyme activity in the group treated with AlCl3. However, there was no significant (p > 0.05) difference in testicular enzyme activity in groups co-administered AlCl3 and BL extract as compared with that in control. There was a significant (p < 0.05) increase in testicular nitrite concentration in the AlCl3-treated group, whereas the administration of BL extract significantly (p < 0.05) decreased nitrite concentration in Groups 3 and 4. Furthermore, the administration of BL extracts increased sperm count and improved the morphology of the testes in AlCl3-treated rats. Flavonoids, phenolic compounds, alkaloids, tannin, glycosides, saponin, anthraquinones, and steroids were identified in BL extract, with alkaloids and glycosides being the most abundant. Conclusion Aqueous extract from BL ameliorated the toxic effect of AlCl3 and exhibited anti-inflammatory properties by inhibiting nitrite production while improving sperm count and morphology in AlCl3-treated rats. The bioactivity of the extract may be attributed to the presence of a wide range of phytochemicals. Therefore, BL aqueous extract could be a promising source of novel compounds with male fertility-promoting and anti-inflammatory properties.

Extremely Active Nano-formulation of Resveratrol (XAR™) attenuates and reverses chemotherapy-induced damage in mice ovaries and testes. J Ovarian Res 2022; 15:115. [PMID: 36271409 PMCID: PMC9585716 DOI: 10.1186/s13048-022-01043-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2022] [Accepted: 09/23/2022] [Indexed: 01/09/2023] Open
Abstract
BACKGROUND Fertility preservation and restoration in cancer patients/survivors is the need of present times when increased numbers of patients get cured of cancer but face infertility as a serious side effect. Resveratrol has beneficial effects on chemoablated ovaries and testes in mice but has failed to enter the clinics because of extremely poor bioavailability. The present study was undertaken to evaluate the protective and curative effects of Extremely active Resveratrol (XAR™)- a nano-formulation of resveratrol with significantly improved bioavailability- on mouse ovary and testis after chemotherapy. Effects of XAR™ and FSH were compared on stimulation of follicle growth in adult mice ovaries. XAR™ (25 mg/kg) was administered for two days prior to chemotherapy to study the protective effects on the mouse gonads. XAR™ was also administered for 14 days post chemoablation to study the regenerative effects. Besides effect on numbers of primordial and growing follicles and spermatogenesis, the effect of XAR™ was also evaluated on the transcripts specific for ovarian/testicular stem/progenitor/germ cells, their proliferation, differentiation, meiosis, and the antioxidant indices. RESULTS Similar to FSH, XAR™ increased the numbers of primordial follicles (PF) as well as growing follicles. It protected the gonads from the adverse effects of chemotherapy and showed the ability to regenerate non-functional, chemoablated gonads. Besides stimulating follicle growth in adult ovaries similar to FSH, XAR™ also protected the testes from the adverse effects of chemotherapy and improved spermatogenesis. This was accompanied by improved anti-oxidant indices. CONCLUSIONS The results of the present study potentiate the use of XAR™ in pilot clinical studies to protect gonadal function during oncotherapy and also regenerate non-functional gonads in cancer survivors by improving antioxidant indices and stem cell-based tissue regeneration.
