Abstract
Fluoride is a common environmental contaminant that has harmful effects on human health when it is present in high concentrations. Fluoride enters the bloodstream after being absorbed by the gastrointestinal system when fluoride-contaminated groundwater is consumed by people. The aim of the present study was to determine whether polyphenol-rich nano Moringa oleifera (NMO) could protect rat testicles from sodium fluoride (NaF) damage by evaluating sperm quality, sex hormones, testicular oxidative status, histopathology, and StAR gene expression. Twenty-eight adult Wistar rats were divided equally and randomly into four groups: group one received distilled water; group two received NMO at a dosage of 250 mg/kg/body weight; group three received NaF at a dosage of 10 mg/kg/body weight; and group four received NaF and NMO. The rats were orally administrated daily for a duration of eight weeks. The study's findings demonstrated that, in comparison to rats exposed to NaF alone, co-administration of NMO and NaF enhanced sperm motility and viability, decreased sperm morphological changes, restored the balance between oxidant and antioxidant status, improved testosterone and dehydroepiandrosterone, improved testicular histology, raised the Johnson score, and upregulated the StAR gene in testicular tissue. These findings show that NMO is promise as a prophylactic medication against sodium fluoride-induced testicular damage because administration of NMO had no adverse effects and enhanced reproductive health.

Abstract
In recent years, fluorosis caused many problems in humans and animals bodies. Dental fluorosis, skeletal fluorosis, bone fractures, decreased birth rates, adverse effects on the male genital system, like damaging the structure of testes and epididymis and loosing fertilization ability can be considered as good examples of fluorosis. Thus, the current study aimed to determine the toxicity of sodium fluoride (NaF) on the activity of sperm and the level of sex hormones including testosterone, follicle stimulating hormone, and luteinizing hormone. For achieving this purpose, thirty adult albino male rats, aged between 90-100 days, were divided randomly into two treated groups with 10 rats for each group which were treated with 150, 300 ppm of sodium fluoride,respectively. In addition, 10 rats were kept as a control group. Sodium fluoride was offered to the treated groups in the drinking water to evaluate the toxic effect of NaF on male reproductive system, sperm concentration, sperm motion, and sperm velocity compared with control group. The findings revealed a significant decrease in the sperm concentration, sperm count, sperm motion, sperm velocity and the level of sexual hormones in comparison with the control group. It can be concluded that NaF may reduce the efficiency of male reproductive system, and reduce the levels of sexual hormones in rats

ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2021; 218:112229. [PMID: 33991993 DOI: 10.1016/j.ecoenv.2021.112229] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/31/2020] [Revised: 03/31/2021] [Accepted: 04/01/2021] [Indexed: 06/12/2023]
Abstract
Bombyx mori was used to study the molecular mechanism of fluoride induced reproductive toxicity. In our previous study, we confirmed the physiological and biochemical effects of NaF on reproductive toxicity, and we found that the molecular mechanism of NaF induced reproductive damage may be associated with the oxidative phosphorylation pathway. To further study the function of NaF exposure on the oxidative phosphorylation pathway in the testis in Bombyx mori, and the relationship between oxidative phosphorylation and oxidative stress, we measured the changes in the main ROS (O2- and H2O2) in the testis, the activity of the main electron transport chain complex enzymes in the oxidative phosphorylation pathway and the transcription levels of the corresponding genes; we additionally performed pathological observations of the silkworm testis after exposure to 200 mg/L NaF solution for different times. The content of O2- and H2O in the silkworm gonads increased significantly at 24 h, 72 h and 120 h after NaF stress. The activity of mitochondrial complexes I, III, IV and V in the silkworm testis was significantly greater than that in the control group. RT-PCR analysis suggested that the mRNA transcription levels of NADH-CoQ1, Cyt c reductase, Cyt c oxidase and ATP synthase genes were up-regulated significantly. Histopathological investigation showed that the damage to the silkworm testis was more severe with increasing NaF exposure times. These results indicated that NaF stress affects the NADH respiratory chain of the mitochondrial electron transport chain and increases the activity of related enzyme complexes, thus destroying the balance of the electron transport chain. Subsequently, the content of ROS in cells significantly increases, thus resulting in oxidative stress reactions in cells. These results enable better understanding of the testis-damaging molecular toxicological mechanism of NaF.

Abstract
Phthalates are common environmental pollutants that are presumed to negatively impact male fertility including animals and humans. Particularly, these potential xenoestrogens may alter male fertility by binding to specific sperm receptors. Although several studies have characterized the toxic effects of single phthalates, epidemiological studies indicate that humans are typically exposed to phthalate mixtures. Here, we tested an environmental-related phthalate combination composed of 21 % di(2-ethylhexyl) phthalate, 15 % diisononyl phthalate, 8% diisobutyl phthalate, 15 % dibutyl phthalate, 35 % diethyl phthalate, and 5% benzylbutyl phthalate. Specifically, the effects of short-term exposure (90 min) to various concentrations (1, 10, 100, and 500 μg/mL) of this phthalate mixture on several important sperm processes, oocyte fertilization, and embryo production were assessed. All phthalate concentrations significantly decreased sperm motility and hyperactivity by compromising the sperm's ability to generate ATP. Additionally, short-term phthalate exposure (>10 μg/mL) also induced abnormal capacitation and the acrosome reaction by upregulating protein tyrosine phosphorylation via a protein kinase-A-dependent pathway. Furthermore, phthalate exposure (particularly at doses exceeding 10 μg/mL) significantly affected fertilization and early embryonic development. Together, our findings indicate that the studied phthalate mixtures adversely affected sperm motility, capacitation, and acrosome reaction, which resulted in poor fertilization rates and repressed embryonic development. Moreover, the lowest-observed-adverse-effect dose of the phthalate mixture tested can be assumed to be < 1 μg/mL in vitro.

Abstract
The present study was undertaken to investigate the toxic effect of sodium fluoride (NaF)- and fluoride (F)-contaminated groundwater on male reproduction and it's reversibility in male rats. Adult male rats were orally treated with different concentrations of NaF- (1 mg, 5 mg, and 10 mg/kg/bw/rat) and F-contaminated groundwater for 52 days and after the confirmation of F-induced damage, the rats were allowed for recovery studies for 52 days. Exposure of NaF- and F-contaminated groundwater caused significant decline in total sperm count, sperm motility, serum concentration of testosterone, activities of testicular 3β-HSDH, counts of type A spermatogonia, preleptotene spermatocytes, midpachytene spermatocytes, elongated spermatids and round spermatids, activities of testicular and spermatozoa SOD and CAT, and increase in sperm abnormality and concentration of MDA of testis and spermatozoa compared to controls. Further, significant histological alterations characterized by shrunken seminiferous tubules and degeneration of different stages of spermatogonial cells were observed in rats treated with NaF of 10 mg/kg/bw and F-contaminated groundwater Majority of parameter studied showed severe damage in 10 mg/kg/bw of NaF-treated rats compared to that of F-contaminated groundwater. Further, dose-dependent alterations were observed with increase in concentration of NaF in most of the parameters. In recovery group rats of NaF- and F-contaminated groundwater, all the parameters were restored to control levels. The present study revealed the toxic effect of NaF and F-contaminated groundwater on male reproductive system of rats and the effects induced by NaF were dose-dependent. In addition, the study clearly revealed that F-induced toxicity on male reproduction is reversible in short-term exposure.

Abstract
Present study was undertaken to investigate the toxic effect of sodium fluoride (NaF)- and fluoride (F)-contaminated ground water on reproductive performances of male rats. Healthy adult male rats were categorised into three groups, first group of rats were served as control, whereas second group of rats were orally intubated with NaF (10 mg/kgbw/1 ml/rat) and third group of rats were allowed to drink F-contaminated ground water (5 mg/L) through drinking water bottles for 52 days. Exposure of NaF- and F-contaminated ground water caused significant decline in sperm motility, serum concentration of testosterone, and increase in sperm abnormality compared with controls. Further, significant histological alterations characterized with shrunken seminiferous tubules and degeneration of different stages of spermatogonial cells were observed in rats treated with NaF- and F-contaminated ground water. After the confirmation of toxic effect of F, these NaF- and F-contaminated ground water-treated male rats were allowed to mate with proven fertile untreated female rats to study the reproductive performances of male rats. There was a decline in parturition index, fertility index of male and female, gestation index and number of pups delivered in NaF-treated male rats compared with controls. However, gestation index and number of pups delivered were declined in F-contaminated ground water-treated male rats compared with controls. These results clearly indicate that F exposure affected the reproductive performances of male rats. The present study further revealed the fact that F-induced decline in testosterone levels, reduced sperm motility, and loss of spermatogonial cells affected the reproductive performances of male rats.

Abstract
The gap junction protein plays an important role in the bone formation and alteration of these proteins leading to cause bone development. Aim to determine the effects of different concentration of fluoride on gap-junctional intercellular communication (GJIC) related genes and proteins in the rats' osteoblast cells. We treated the osteoblast cells with various concentrations (0, 0.01, 0.1, 0.5, and 1.0 mM) NaF for 24 and 72 h. We used the scrape loading and dye transfer technique to research the intracellular connectivity. Moreover, the mRNA expression levels of connexin 43 (Cx43), connexin45 (Cx45), collagen I, and osteocalcin (OCN) were analyzed by qRT-PCR, the protein expression levels of connexin43 (Cx43) were analyzed by western blotting and immunofluorescence. Our results suggested that the osteoblast proliferations were decreased in the 0.5 and 1 mM NaF groups, after 24 and 72 treatments. The scrape loading and dye transfer experiment showed that the GJIC were increased in the 0.01 mM NaF group and decreased in the 0.5 and 1 mM NaF groups. In addition, the mRNA expressions of Cx43, Cx45, and OCN, and the protein expressions of Cx43 were increased in the 0.01 mM NaF group and decreased in the 0.5 and 1 mM NaF groups. In summary, these results suggest that the low concentration NaF is good for the GJIC, but the high concentration NaF damages the GJIC.

Abstract
Diabetes mellitus is the most common chronic disease worldwide that causes numerous complications, including male infertility. The prevalence of DM is 451 million people and estimated that would increase to 693 million in 2045. Fluorosis caused by drinking water contaminated with inorganic fluoride is a public health problem in many areas around the world. Previous studies have shown that fluoride exposure damages the male reproductive function. This study aimed to evaluate the fluoride sub-chronic exposure on the spermatozoa function in streptozotocin (STZ)-induced diabetic mice. After confirming diabetes by measuring blood glucose levels, the male mice received 45.2 ppm of fluoride added or deionized water. We evaluated several parameters in diabetic mice exposed to fluoride: standard quality analysis, the mitochondrial transmembrane potential (ψm), the caspase activity in spermatozoa, urinary fluoride excretion, and histological evaluation in the testes. After 60 days of fluoride-exposure, diabetic mice, significantly decreased sperm quality (motility, viability, and concentration). Spermatozoa from fluoride-exposure in diabetic mice presented a significant decrease in ψm and a significant increase in activity caspase 3/7. Urinary fluoride excretion was decreased in diabetic mice exposed to fluoride. Subchronic fluoride exposure of mice with STZ-induced diabetes aggravated testicular damage and the spermatozoa function.

Abstract
The effect of fluoride as an ongoing topic has attracted much attentions due to the decline in overall human fertility worldwide. However, whether fluorine causes a temporary stimulus or permanent damage to the male reproductive system, as well as the mechanism of fluoride influencing spermatogenesis remained unclear. 48 adult male rats were randomly divided into four groups (twelve each). Control group received the distilled water, while the other three groups were treated with 25, 50, 100 mg/L NaF via drinking water for 8 weeks. Six rats from each group were selected randomly to detect the levels of various indices related to spermatogenesis. The remaining rats were given only distilled water and left for recovery of a period of 2 weeks. Results showed that the levels of serum CK, ALP, CHE, BUN, UA, and Cr, testis morphology and the ultrastructure of sperm acrosome and chromatoid body (CB) were significantly changed by fluoride. Interestingly, the elongated spermatid counts, spermatids elongation ratio, and mRNA expressions of Prm1/2 and MIWI, TDRD1, TDRD 6, TDRD7, PABP, and Hsp72 related to CB decreased markedly in fluoride treatment groups compared to the control. Furthermore, the expression levels of DDX25 and associated regulatory proteins like CRM1, HMG2, H4, TP2, and PGK2 were down-regulated by fluoride. After 2-weeks withdrawal period, out of the 19 altered spermatogenesis indicators, 15 indicators in 100 mg/L group and 3 indicators in 50 mg/L group still exhibited a significant change, while none showed change in 25 mg/L group. These results proved that the reversibility of fluoride toxicity is dose-dependent on the male reproductive system. Meanwhile, fluoride caused unrestored arrest during the haploid period of spermatogenesis, where reduced DDX25 and associated regulatory proteins play a crucial role in this process, which could provide the underlying insights to the toxic mechanism of fluoride induced male reproductive toxicity.

Abstract
The exposure and health effects of fluoride are an ongoing topic that has attracted worldwide attention. Fluoride exposure disturbs the testicular development, sexual hormone levels and spermatogenesis. However, as to whether fluoride interferes with acrosome formation which is essential for production of capable spermatozoa during spermatogenesis still remains unclear. The objective was to determine the effects of fluoride on the acrosome formation and to further elucidate the potential mechanism of impaired reproductive function. For this, forty adult rats were assigned into four groups. The control group received distilled water, while the other three groups were treated with 25, 50 and 100 mg NaF/L via drinking water for 56 d, respectively. Testes were processed for total RNA extraction and western blot analysis. Three samples of each group were fixed in 2.5% glutaraldehyde solution for transmission electron microscopy analysis. From the results, we first found that fluoride decreased the expression of mRNA and protein levels of Zpbp1, Spaca1 and Dpy19l2 of seven markers during acrosome biogenesis in testes. Furthermore, fluoride damaged not only the acrosome structure, but also the structure of the nuclear lamina which was observed to be discontinuous and partially missing by transmission electron microscopy. Moreover, the results indicated that the altered structure in nuclear lamina maybe due to reduced LMNB2 expression in testis induced by fluoride. In a nutshell, fluoride exposure could restrain acrosome biogenesis during spermatogenesis and contribute to the elucidation of the underlying mechanisms of fluoride-induced male reproductive toxicity.

Abstract
Geniposide, as a type of iridoid glycoside, has antioxidative capacity. However, the mechanism underlying the effect of geniposide in cadmium (Cd)-induced osteoblast injury remains only partly elucidated. In the present study, Cell Counting Kit-8 (CCK-8) was used to determine MC-3T3-E1 cell viability. Flow cytometry was used to determine the rate of apoptosis and levels of reactive oxygen species (ROS). Oxidative stress-related factors were assessed using enzyme-linked immunosorbent method (ELISA). Quantitative real-time polymerase chain reaction (qPCR) and western blotting were used to evaluate apoptosis- and bone formation-related genes and nuclear factor erythroid 2-related factor (Nrf2) signaling. It was demonstrated that geniposide increased the viability of the Cd-treated MC-3T3-E1 cells. Geniposide decreased apoptosis and ROS accumulation compared to these parameters in the Cd group. Geniposide attenuated oxidative stress-related factors, malondialdehyde and lactate dehydrogenase and increased antioxidant key enzyme superoxidase dismutase (SOD). The expression levels of Bax, Bcl-2 and survivin were modulated by geniposide. Additionally, the mRNA and protein expression of the receptor activator of NF-κB ligand (RANKL) and osterix were significantly increased, while osteoprotegerin was decreased by geniposide treatment compared to the Cd groups. Geniposide also enhanced Nrf2, heme oxygenase-1 (HO-1) and NAD(P)H quinone dehydrogenase 1 (NQO1) expression. The present study identified a potential agent for the treatment of Cd-induced osteoblast injury.

Abstract
Fluoride is a widespread environmental pollutant that can induce low sperm quality and fertilizing ability; however, the underlying mechanism still remains unclear. Hence, we aimed to investigate the influence of fluoride on the sperm fertilizing ability via some key proteins in the epididymis. For this, 40 adult rats were assigned randomly into four groups. The control group was given distilled water, while the other three groups were given 25, 50, and 100 mg of NaF/L via drinking water for 56 days, respectively. After 1 day, epididymides were processed for sperm-egg binding, RNA extraction, western blot, and immunofluorescence analysis. Fluoride exposure reduced the ability of sperm to break down the egg cumulus cell layer. A further study revealed that fluoride altered the expression levels of genes and proteins related to acrosome reaction in vivo, including SPAM1, ACR, and PRSS21. However, fluoride only affected the expression of the ACR protein only in the epididymis but not in the testis. Fluoride also affected the expression levels of the membrane proteins CD9 and CD81 of epididymosomes in the epididymis. From the results, it can be concluded that fluoride exposure reduced the ability of sperm to break down the egg cumulus cell layer, which could be one of the reasons for decreased fertility ability in males treated with fluoride. These results provide some theoretical guidance and new ideas for treatments of low fertility, infertility, and other reproductive diseases.

Abstract
The present study was undertaken to investigate the toxic effect of ground water fluoride (F) on motility, abnormality, and antioxidant status of spermatozoa. Treatment of ground water F with epididymal sperm suspension caused complete loss of sperm motility and decrease in the activities of superoxide dismutase (SOD) and catalase (CAT) and increase in the concentration of malondialdehyde (MDA) and abnormality of spermatozoa at 15 and 30 min time intervals. Further, incubation of spermatozoa with ground water F for 5, 10, and 15 min time intervals significantly reduced the sperm motility and activities of SOD and CAT and increased the concentration of MDA and abnormality of spermatozoa. The study revealed that F-induced effect on sperm motility and antioxidant status is time dependent. Increase in oxidative stress and concomitant decrease in motility of spermatozoa in ground water F clearly indicates that F-induced oxidative stress affected the sperm motility. The present study for the first time demonstrated the toxic effect of ground water F on spermatozoa at shorter duration of exposure, which affects the capability of spermatozoa in fertilization.

Abstract
Fluorine is one of the trace elements necessary for health. It has many physiological functions, and participates in normal metabolism. However, fluorine has paradoxical effects on the body. Many studies have shown that tissues and organs of humans and animals appear to suffer different degrees of damage after long-term direct or indirect exposure to more fluoride than required to meet the physiological demand. Although the aetiology of endemic fluorosis is clear, its specific pathogenesis is inconclusive. In the past 5 years, many researchers have conducted in-depth studies into the pathogenesis of endemic fluorosis. Research in the areas of fluoride-induced stress pathways, signalling pathways and apoptosis has provided further extensive knowledge at the molecular and genetic level. In this article, we summarize the main results.

Abstract
Fms-like tyrosine kinase 3 (FLT3) is a type III kinase that is highly expressed in seminal plasma of infertile men. FLT3 activation can be blocked by inhibition of its phosphorylation using the nontoxic and selective inhibitor, quizartinib. We investigated the function of FLT3 and the corresponding effects of quizartinib in mouse spermatozoa. Spermatozoa were treated with different concentrations (0.1, 1, 10, 20, and 30 μM) of quizartinib for 90 min at 37 °C in 5% CO2 in air. FLT3 was detected in capacitated and non-capacitated spermatozoa. While the level of FLT3 was unaffected, the levels of phospho-FLT3 were significantly altered in spermatozoa by quizartinib. Exposure of spermatozoa to higher concentrations of quizartinib significantly altered sperm viability, motility, motion kinematics, levels of intracellular ATP, and capacitation status. Fertilization and early embryonic development were suppressed by quizartinib. This may have occurred as a consequence of decreased protein kinase A (PKA) activity and tyrosine phosphorylation. The inhibition of FLT3 by quizartinib may affect the fertilization and embryonic development by reducing tyrosine phosphorylation through a PKA-dependent pathway. Our data implicate FLT3 as a biomarker for diagnosis and prognosis of male fertility. In addition, quizartinib has potential for development as a new contraceptive agent.

Abstract
Bombyx mori was used as a model to evaluate the reproductive toxicity of NaF in insects. Significant reduction in cocoon quality, survival rate, fecundity, and hatchability were observed upon NaF treatment groups. Fluoride determination indicated that F- has a cumulative effect on the gonad of silkworm. High-performance liquid chromatography revealed that the testosterone content of males was decreased in NaF-treated groups, and enzyme-linked immunosorbent assay showed that the estradiol content was decreased in NaF-treated females. Ultrastructural observation of testicles of silkworm larvae revealed mitochondrial turgescence, endoplasmic reticulum destruction, the appearance of vacuoles and lysosomes, and apoptosis and necrosis of cells in NaF-treated groups. Altered tail length and tail DNA content in Comet assays further confirmed DNA damage in NaF-treated larvae. We demonstrated reproductive toxicity of fluoride toward silkworm at physiological and biochemical levels, and the results provide a theoretical basis for revealing the reproductive toxicity of fluoride in terrestrial insects.

Abstract
The present study was undertaken to investigate the toxic effects of sodium fluoride (NaF) on sperm motility and abnormality. Treatment of epididymal sperm suspensions with different doses of NaF (0.1, 1, 10, and 100 mg/ml) significantly reduced sperm motility at 15- and 30-min time intervals. Further, incubation at the same concentrations of NaF for 5-, 10-, and 15-min time intervals decreased sperm motility in a dose- and time-dependent manner. The present investigation revealed for the first time the adverse effect of lower doses of NaF (0.1 mg/ml) on sperm motility. Further, higher doses of NaF (10 and 100 mg/ml) caused a complete loss of sperm motility with a concomitant increase in sperm abnormality, which reflected the toxic effect of NaF on spermatozoa and its capability in fertilization.

Abstract
Quercetin, a plant-derived flavonoid, is frequently used as an antioxidant for efficient anti-oxidative capacity. However, whether quercetin has protective effects on goat sperm and preimplantation embryos against Cd2+-induced oxidative injury is still unclear. So, we researched the influence of quercetin on goat sperm and zygotes respectively under the oxidative stress induced by Cd2+. In our study, quercetin decreased the malonaldehyde (MDA) and reactive oxygen species (ROS) levels caused by Cd2+ in goat sperm (p < 0.05), which facilitated sperm characteristics including motility, survival rates, membrane integrity, and mitochondria activity during storage in vitro and subsequent embryo development (p < 0.05). Moreover, in goat zygotes, quercetin decreased peroxidation products including ROS, MDA, and carbonyl through preserving or maintaining mitochondrial function, gene expression, and anti-oxidative products such as glutathione peroxidase, superoxide dismutase, and catalase, which ameliorated subsequent embryo development and embryo quality (p < 0.05). Taken together, these results suggest that quercetin protects both goat sperm and preimplantation embryos from Cd2+-induced oxidative stress.

Abstract
Fluoride is a widespread environmental pollutant which can induce low sperm quality and fertilizing ability. However, effect of fluoride on proteomic changes of sperm is unknown. In this study, two-dimensional electrophoresis (2DE) and mass spectrometry (MS) were used to investigate the differently expressed proteins of sperm from mice exposed to fluoride. 180 male mice were randomly divided into three groups, and were administrated with the distilled water containing 0, 25, and 100 mg L-1 NaF, respectively. After 45, 90 and 180 day's exposure, mice were sacrificed and sperm from the cauda epididymis and vas deferens were collected for 2DE. 16 differently expressed spots were picked up to identify using MS, 15 of which were successfully identified. Many of them are associated with the sperm function such as sperm motility, maturation, capacitation and acrosome reaction, lipid peroxidation, detoxification, inflammation, and stability of membrane structure. These results could contribute to the explanation and further research of mechanisms underlying sperm damage induced by fluoride.

Abstract
Fluorine is an essential element, but excessive fluoride can cause serious effects on the respiratory, digestive, and reproductive systems. Fluorine has been suggested to cause reproductive toxicity in vertebrates, but its potential to reproductively affect invertebrates remains unknown. In the present study, the lepidopteran model insect Bombyx mori was used to assess the reproductive toxicity of NaF. The underlying molecular mechanisms were explored by RNA sequencing, and we investigated the testes transcriptomic profile of B. mori treated with NaF via a digital gene expression (DGE) analysis. Among 520 candidate genes, 297 and 223 were identified as significantly upregulated or downregulated, respectively. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were carried out on all genes to determine their biological functions and associated processes. The results indicated that numerous differentially expressed genes are involved in the stress response, detoxification, antibacterial, transport, oxidative phosphorylation, and ribosome. The reliability of the data was confirmed by a quantitative real-time polymerase chain reaction (qRT-PCR) analysis. The changed Glutathione S-transferase (GST) activity and glutathione (GSH) content in the NaF-treated groups were increased and reduced respectively. This study reveals that using RNA-sequencing for the transcriptome profiling of B. mori testes can lead to better comprehension of the male reproductive toxicity effects of NaF. Furthermore, we expect that these results will aid future molecular studies on the reproductive toxicity of NaF in other species.

ENVIRONMENTAL AND MOLECULAR MUTAGENESIS 2018; 59:223-233. [PMID: 29285797 DOI: 10.1002/em.22165] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/19/2017] [Revised: 11/06/2017] [Accepted: 12/05/2017] [Indexed: 06/07/2023]
Abstract
Sodium fluoride (NaF) is used as a medicine to prevent tooth decay; however, excessive NaF could cause a pathological damage to the health. Recent studies showed that NaF impaired mouse oocyte maturation, included of abnormal spindle configuration, actin cap formation, cortical granule-free domain formation, and the following development after fertilization. However, few studies used large animals as models to study the toxicology of NaF on oocytes maturation. We proposed a hypothesis that NaF would affect the nuclear and cytoplasmic maturation of porcine oocytes and DNA methylation pattern of imprinted genes in oocytes. Our results showed that NaF affected cumulus expansion, polar body emission, spindle morphology, cortical granule distribution, early apoptosis, and the following development after parthenogenetic activation during porcine oocyte maturation. Moreover, NaF increased the DNA methylation of NNAT and decreased its expression, which disturbed the glucose transport in oocytes. These results suggest that NaF impairs the porcine oocytes maturation epigenetically, which provides a new toxicological mechanism of NaF on the oocyte maturation. Environ. Mol.

Abstract
Peroxiredoxins (PRDXs) are important antioxidant enzymes reported to have a role in sperm function and male fertility. However, how PRDXs affects male fertility remain fundamental unanswered questions. We therefore sought to investigate the role of these enzymes in sperm function and fertilisation. In this in vitro trial, mouse spermatozoa were incubated with different concentrations of conoidin A (1, 10, or 100 µM), a specific inhibitor of PRDXs. Our results demonstrated that inhibition of PRDXs by conoidin A significantly decreased the oxidized form of peroxiredoxins (PRDXs-SO3) in spermatozoa. Decreased PRDX activity was associated with a significant reduction in sperm motility parameters, viability, and intracellular ATP, whereas ROS levels, DNA fragmentation, and loss of mitochondrial membrane potential were increased. Simultaneously capacitation and the acrosome reaction were also significantly inhibited perhaps as a consequence of decreased tyrosine phosphorylation and protein kinase-A activity. In addition, fertilisation and early embryonic development were adversely affected following PRDXs inhibition in spermatozoa. Taken together, our data demonstrate that decreased PRDX activity directly affects male fertility due to negative effects on important functions and biochemical properties of spermatozoa, ultimately leading to poor fertilisation and embryonic development.

Abstract
Post-testicular sperm maturation and storage within the epididymis is a key determinant of gamete quality and fertilization competence. Here we demonstrate that mouse spermatozoa possess a complex small non-protein-coding RNA (sRNA) profile, the composition of which is markedly influenced by their epididymal transit. Thus, although microRNAs (miRNAs) are highly represented in the spermatozoa of the proximal epididymis, this sRNA class is largely diminished in mature spermatozoa of the distal epididymis. Coincident with this, a substantial enrichment in Piwi-interacting RNA (piRNA) abundance in cauda spermatozoa was detected. Further, features of cauda piRNAs, including; predominantly 29-31 nts in length; preference for uracil at their 5' terminus; no adenine enrichment at piRNA nt 10, and; predominantly mapping to intergenic regions of the mouse genome, indicate that these piRNAs are generated by the PIWIL1-directed primary piRNA production pathway. Accordingly, PIWIL1 was detected via immunoblotting and mass spectrometry in epididymal spermatozoa. These data provide insight into the complexity and dynamic nature of the sRNA profile of spermatozoa and raise the intriguing prospect that piRNAs are generated in situ in maturing spermatozoa. Such information is of particular interest in view of the potential role for paternal sRNAs in influencing conception, embryo development and intergenerational inheritance.

Abstract
It is well known that high fluoride results in low fertility. Epididymis is the important place for spermatozoa maturation, which is essential for successful fertilization. In the previous studies, fluoride was reported to damage the epididymal structure of mouse and rabbit. However, the mechanism underlying sodium fluoride (NaF)-induced epididymal toxicity has not yet been well elucidated. The aim of this study is to explore the global protein alterations in epididymis of mice exposed to NaF using the iTRAQ technique. Results showed that 211 proteins were differentially expressed in both 25 and 100 mg/L NaF groups. Some of them have been proved to be important for reproduction, such as low-density lipoprotein receptor-related protein 2 (Lrp2), cytochrome c, testis-specific (Cyct), sorbitol dehydrogenase (Sord), glutathione S-transferases (GSTs), acrosin, beta-defensin 126, cysteine-rich secretory protein (Crisp) 1, and Crisp2. Gene ontology (GO) analysis suggested cellular process, organelle and catalytic activity account for high percent and number of differentially expressed proteins. 171 pathways were found after the Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis, among which the representative maps, such as ribosome, focal adhesion, and phagosome, were involved. Different functional categories post-translational modification, protein turnover, chaperones; translation, ribosomal structure and biogenesis; cytoskeleton; energy production and conversion are implicated in the Cluster of Orthologous Groups (COG) of proteins analysis. Subsequently, the effect of NaF on the antioxidant activity in epididymis, especially glutathione and glutathione-related enzymes, was evaluated. Results exhibited high fluoride caused low total antioxidant capacity (T-AOC), high methane dicarboxylic aldehyde (MDA), decreased reduced glutathione (GSH), and the glutathione-related enzymes [GSH peroxidase (GPx), GSH reductase (GR), and GSH S-transferase (GST)] changes in activity, protein, and mRNA expressions. In summary, NaF decreased the antioxidant activity of epididymis, especially glutathione and glutathione-related enzymes, as well as iTRAQ results, providing new explanations for the low sperm quality induced by fluoride.

Abstract
Aminopeptidase N (APN) is a naturally occurring ectopeptidase present in mammalian semen. Previous studies have demonstrated that APN adversely affects male fertility through the alteration of sperm motility. This enzyme constitutes 0.5 to 1% of the seminal plasma proteins, which can be transferred from the prostasomes to sperms by a fusion process. In the present study, we investigated the molecular mechanism of action of APN and its role in regulating sperm functions and male fertility. In this in vitro study, epididymal mouse spermatozoa were incubated in a capacitating media (pH 7) containing 20 ng/mL of recombinant mouse APN for 90 min. Our results demonstrated that the supplementation of recombinant APN in sperm culture medium significantly increased APN activity, and subsequently altered motility, hyperactivated motility, rapid and medium swimming speeds, viability, and the acrosome reaction of mouse spermatozoa. These effects were potentially caused by increased toxicity in the spermatozoa. Further, altered APN activity in sperm culture medium affected early embryonic development. Interestingly, the effect of elevated APN activity in sperm culture medium was independent of protein tyrosine phosphorylation and protein kinase A activity. On the basis of these results, we concluded that APN plays a significant role in the regulation of several sperm functions and early embryonic development. In addition, increased APN activity could potentially lead to several adverse consequences related to male fertility.

Abstract
Fluoride is known to cause male reproductive toxicity, and the elucidation of its underlying mechanisms is an ongoing research focus in reproductive toxicology and epidemiology. Choline, an essential nutrient, has been extensively studied for its benefits in nervous system yet was rarely discussed for its prospective effect in male reproductive system. This study aims to explore the potential protective role of choline against NaF-induced male reproductive toxicity via MAPK pathway. The male mice were administrated by 150mg/L NaF in drinking water, 5.75g/kg choline in diet, and their combination respectively from maternal gestation to postnatal 15weeks. The results showed that fluoride exposure reduced body weight growth, lowered sperm count and survival percentages, altered testicular histology, down-regulated the mRNA expressions of NGF, Ras, Raf, and MEK genes in testes, as well as significantly decreased the expressions of both NGF and phosphor-MEK proteins in testes. Examination of data from choline-treated mice revealed that choline supplementation ameliorated these fluoride-induced changes. Taken together, our findings suggest that choline supplementation alleviates fluoride-induced testicular toxicity by restoring the NGF and phosphor-MEK expression. The suitable dosage and supplementation periods of choline await further exploration.

Role of IL-17 Pathways in Immune Privilege: A RNA Deep Sequencing Analysis of the Mice Testis Exposure to Fluoride. Sci Rep 2016; 6:32173.

Abstract
We sequenced RNA transcripts from the testicles of healthy male mice, divided into a control group with distilled water and two experimental groups with 50 and 100 mg/l NaF in drinking water for 56 days. Bowtie/Tophat were used to align 50-bp paired-end reads into transcripts, Cufflinks to measure the relative abundance of each transcript and IPA to analyze RNA-Sequencing data. In the 100 mg/l NaF-treated group, four pathways related to IL-17, TGF-β and other cellular growth factor pathways were overexpressed. The mRNA expression of IL-17RA, IL-17RC, MAP2K1, MAP2K2, MAP2K3 and MAPKAPK2, monitored by qRT-PCR, increased remarkably in the 100 mg/L NaF group and coincided with the result of RNA-Sequencing. Fluoride exposure could disrupt spermatogenesis and testicles in male mice by influencing many signaling pathways and genes, which work on the immune signal transduction and cellular metabolism. The high expression of the IL-17 signal pathway was a response to the invasion of the testicular immune system due to extracellular fluoride. The PI3-kinase/AKT, MAPKs and the cytokines in TGF-β family were contributed to control the IL-17 pathway activation and maintain the immune privilege and spermatogenesis. All the findings provided new ideas for further molecular researches of fluorosis on the reproduction and immune response mechanism.

Abstract
The reproductive toxicity of fluoride has become a major concern in the world. Fluoride can decrease the abilities of sperm capacitation, hyperactivation, chemotaxis, acrosome reaction and fertilization, but the studies on the responses of sperm small noncoding RNAs (sncRNAs), especially miRNAs, to fluoride exposure are lacking. miRNAs are demonstrated to influence sperm quality and male fertility by regulating gene expression at post-transcriptional levels or translational repression. The objective of this study is to analyze miRNA profiling in sperm of mice administrated with 25 and 100 mg L(-1) sodium fluoride (NaF) for 60 d using high-throughput sequencing technology. Along with reduced sperm concentration, survival, motility, and mitochondrial membrane potential, 31 differentially expressed known miRNAs were identified in fluoride groups, compared with the control group. 671 predicted target genes against the 16 altered miRNAs were mainly involved in protease inhibitor activity, apoptosis, ubiquitin mediated proteolysis, and signaling pathways of calcium, JAK-STAT, MAPK, p53, Wnt, which were proved to be directly related to sperm quality. These findings suggested that the altered sperm miRNAs could be potential biomarkers for fluoride reproductive toxicity.

Abstract
Fluoride and sulfur dioxide (SO2), two well-known environmental toxicants, have been implicated to have adverse effects on male reproductive health in humans and animals. The objective of this study to investigate if the BTB is one of the pathways that lead to reproductive toxicity of sodium fluoride and sulfur dioxide alone or in combination, in view of the key role of blood testis barrier (BTB) in testis. The results showed that a marked decrease in sperm quality, and altered morphology and ultrastructure of BTB in testis of mice exposure to fluoride (100 mg NaF/L in drinking water) or/and sulfur dioxide (28 mg SO2/m(3), 3 h/day). Meanwhile, the mRNA expression levels of some vital BTB-associated proteins, including occluding, claudin-11, ZO-1, Ncadherin, α-catenin, and connexin-43 were all strikingly reduced after NaF exposure, although only the reduction of DSG-2 was statistically significant in all treatment groups. Moreover, the proteins expressions also decreased significantly in claudin-11, N-cadherin, α-catenin, connexin-43 and desmoglein-2 in mice treated with fluoride and/or SO2. These changes in BTB structure and constitutive proteins may therefore be connected with the low sperm quality in these mice. The role of fluoride should deserves more attention in this process.

In silico prediction of microRNAs on fluoride induced sperm toxicity in mice. Food Chem Toxicol 2016; 98:34-49. [PMID: 27012587 DOI: 10.1016/j.fct.2016.03.005] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2016] [Revised: 03/07/2016] [Accepted: 03/10/2016] [Indexed: 01/06/2023]
Abstract
Fluorosis is an endemic global problem causing male reproductive impairment. F mediates male reproductive toxicity in mice down-regulating 63 genes involved in diverse biological processes - apoptosis, cell cycle, cell signaling, chemotaxis, electron transport, glycolysis, oxidative stress, sperm capacitation and spermatogenesis. We predicted the miRNAs down-regulating these 63 genes using TargetScan, DIANA and MicroCosm. The prediction tools identified 3059 miRNAs targeting 63 genes. Of the predicted interactions, 11 miRNAs (mmu-miR-103, -107, -122, -188a, -199a-5p, -205, -340-5p, -345-3p, -452-5p, -499, -878-3p) were commonly found in the three tools utilized and seven miRNAs (miR-9-5p, miR-511-3p, miR-7b-5p, miR-30e-5p, miR-17-5p, miR-122-5p and miR-541-5p) targeting six genes (Traf3, Rock2, Rgs8, Atp1b2, Cacna2d1 and Aldoa) were already validated experimentally in mice. The miRNA-mRNA network of the predicted miRNAs with its respective targets revealed the complex interaction within a biological process leading to sperm dysfunction on exposure to F. Our findings not only suggest that the predicted miRs furnish evidence, but also have the potential to serve as non-invasive biomarkers on F-induced sperm dysfunction. Our data contribute towards elucidating the function of miRNAs in the fluoride induced infertility. miRNA molecular pathways in F intoxication will open new avenues on the use of antagomirs in recovering fertility.

[PMID: 26439518 DOI: 10.1016/j.chemosphere.2015.09.061] [Citation(s) in RCA: 41] [Impact Index Per Article: 5.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/17/2015] [Revised: 09/11/2015] [Accepted: 09/14/2015] [Indexed: 06/05/2023]
Abstract
Fluoride-induced low sperm motility was observed in accumulated investigations. However, the effect of fluoride exposure on ATP generation which is essential to sperm motility remains to be elucidated. In this study, 120 healthy male mice were orally administrated with 0, 25, 50, and 100 mg L(-1) NaF for 90 d. Results showed that compared with controls, fluoride ingestion significantly reduced sperm count, survival, as well as mobility and total ATP level in sperm untreated with carbonyl cyanide m-chlorophenylhydrazone (CCCP) or pyruvate, which was used to establish glycolysis or mitochondrial respiration model, respectively. Data further revealed that sperm mobility and ATP level under mitochondrial respiration condition were significantly suppressed, while no statistical difference occurred in the model of glycolysis, indicating ATP derived from mitochondria was affected. Moreover, mRNA expressions of mitochondrial cytochrome b (mt-Cytb) and cytochrome c oxidase subunit 2 (mt-COX2), two important molecules in mitochondrial electron transport chain (ETC), were down-regulated in all fluoride treatment groups. Mitochondria in sperm of mice exposed to 100 mg L(-1) NaF appeared to be irregular and vacuolated. These findings suggested that decreased sperm motility induced by fluoride may result from low ATP generation due to the disturbed ETC in sperm mitochondrial.
