[PMID: 37245696 DOI: 10.1016/j.reprotox.2023.108414] [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: 02/06/2023] [Revised: 05/05/2023] [Accepted: 05/25/2023] [Indexed: 05/30/2023]
Abstract
Cypermethrin (CYP) has been identified as one kind of endocrine-disrupting chemicals (EDCs) to induce male reproduction damage. This study aimed to investigate the effects and mechanisms of miR-30a-5p on CYP induced apoptosis of TM4 mouse Sertoli cells in vitro. In the present study, 0 μM, 10 μM, 20 μM, 40 μM and 80 μM CYP were used to treat TM4 cells for 24 h. The apoptosis of TM4 cells, the expression level of miR-30a-5p, the protein expressions and the interaction between miR-30a-5p and KLF9 were detected by flow cytometry, quantitative Real-Time PCR, Western blot and luciferase reporter assays. CYP induced apoptosis of TM4 cells, inhibited expression of miR-30a-5p in TM4 cells, and overexpression of miR-30a-5p partially recovered CYP induced cells apoptosis. Furthermore, KLF9 was a potential downstream target of miR-30a-5p predicted by publicly available databases. KLF9 expression level in TM4 cells was significantly elevated after treatment with CYP, and the induction was inhibited by miR-30a-5p mimics transfection. Meanwhile, dual-luciferase reporter assay demonstrated that miR-30a-5p directly targeted KLF9-3'UTR. Moreover, in the presence of CYP, the apoptosis regulator p53 expression was also increased in TM4 cells. Overexpression miR-30a-5p or down-regulation of KLF9 both attenuated the induction of CYP on p53 expression. Overall, the present study demonstrated that miR-30a-5p regulated CYP induced TM4 cells apoptosis by targeting KLF9/p53 axis.

[PMID: 34729871 DOI: 10.1111/jog.15087] [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: 05/22/2021] [Revised: 10/11/2021] [Accepted: 10/17/2021] [Indexed: 11/30/2022]
Abstract
AIM To investigate the protective effect of small peptides from Periplaneta americana (SPPA) on cyclophosphamide (CP)-induced premature ovarian failure (POF) in mice. Silent mating type information regulation 2 homolog 1 (SIRT1) /tumor-associated protein 53 (p53) signaling pathway plays an important role in delaying POF. Hematopoietic progenitor cell antigen (CD34) reflects ovarian aging from the side. However, whether SPPA inhibits POF in mice by influencing the SIRT1/p53 pathway and CD34 expression remains to be studied. METHODS Forty female Kun Ming (KM) mice were divided into four groups: a control group (normal saline, n = 10), POF model group (160 mg/kg CP, n = 10), SPPA low-dosage group (160 mg/kg CP + 100 mg/kg SPPA, n = 10), and SPPA high-dosage group (160 mg/kg CP + 200 mg/kg SPPA, n = 10). CP administration route is intraperitoneal injection, and SPPA administration route is intragastric. Eyeball enucleation blood samples and the ovaries of mice were collected by midline laparatomy and oopherectomy, and the malondialdehyde (MDA), nitric oxide (NO), superoxide dismutase (SOD), follicle-stimulating hormone (FSH), and anti-Müllerian hormone (AMH) concentrations were tested. Immunohistochemical tests for the expressions of SIRT1, p53, and CD34 were carried out. Finally, ovarian mRNA levels of SIRT1 and p53 were detected with real-time fluorescence quantification PCR (qRT-PCR). RESULTS A mouse model of POF was generated using 160 mg/kg of CP. Compared with POF group, we found that plasma NO, MDA, and FSH decreased, while AMH and SOD increased in the SPPA low-dose group. Compared with the POF group, the SPPA low- and high-dosage groups achieved significant growth in the number of primordial, primary, and total number of healthy follicles at all levels, but sharp reductions in the number of atretic follicles. In addition, we found downregulated protein and mRNA expression of SIRT1, and upregulated that of p53 were observed in ovarian tissues of treated mice with POF, in immunohistochemistry experiments and qPCR experiments. In contrast, high protein and mRNA expression of SIRT1, and low that of p53 were observed in SPPA treatment groups. And the results of CD34 protein expression were consistent with that of SIRT1. CONCLUSION In total, SPPA significantly inhibited POF caused by CP in mice via activation of the SIRT1/p53 signaling pathway in the mouse ovary.

Abstract
Cypermethrin, a type II pyrethroid pesticide, is one of the most widely used pesticides in agricultural and in household settings. The toxic effects of cypermethrin are a matter of concern, as humans are almost inevitably exposed to it in daily life. It is an urgent problem to seek natural substances from plants that can eliminate or relieve the effects of pesticide residues on human health. Proanthocyanidins are the most potent antioxidants and free radical scavengers in natural plants, and are widely available in fruits, vegetables, and seeds. We found that proanthocyanidins (1, 2.5, and 5 μg/mL) can decrease ROS generation, relieve mitochondrial membrane potential loss, repair nuclear morphology, reduce cell apoptosis, and protect neurons from cypermethrin-induced oxidative insult. The protective mechanism exerted by proanthocyanidins against cypermethrin-induced neurotoxicity is negatively regulate rather than activate the Nrf2/ARE signaling pathway to maintain intracellular homeostasis.

Abstract
This study investigates the protective effect of small peptides from Periplaneta americana (SPPA) on hydrogen peroxide (H2O2)-induced apoptosis of ovarian granular cells. H2O2 was applied to human ovarian granular cells (KGN cell strains). Cell viability was tested by cell counting Kit-8 (CCK-8). Cell apoptosis was tested by flow cytometry, and a cell apoptosis model was established. The model cells were treated with SPPA, and the cell survival rate was monitored using the CCK-8 method. The oxidative stress state of cells was examined using SOD, ROS, MDA, and NO kits. The protein expression levels of SIRT1, p53, and the apoptosis-related gene Caspase3 were measured using Western Blot methodology. Relative to the control group, cell viability declined significantly after the H2O2 treatment only (P < 0.01), while the apoptosis rate increased significantly (P < 0.01). The activity of SOD was weakened significantly (P < 0.01), while the cell levels of ROS, MDA, and NO increased dramatically (P < 0.01). Cell viability dramatically recovered (P < 0.01), and the SOD activity is hugely increased (P < 0.01) after SPPA treatment. In contrast, contents of ROS, MDA, and NO decreased sharply (P < 0.01), and significant dose-response relationships are characterized. Moreover, the H2O2 treatment group showed significantly downregulated expression of SIRT1 (P < 0.01) but significantly upregulated expressions of p53 and Caspase3 (P < 0.01) compared to the control group. Following the SPPA treatment of apoptosis cells, expression of SIRT1 increased significantly, while expressions of p53 and Caspase3 declined significantly (P < 0.01). This study suggests that SPPA inhibits H2O2-induced human KGN cell apoptosis through antioxidation, and the SIRT1/p53 signal pathway mediates the antioxidation.

Abstract
Ribonucleic acid (RNA) molecules can be easily attacked by reactive oxygen species (ROS), which are produced during normal cellular metabolism and under various oxidative stress conditions. Numerous findings report that the amount of cellular 8-oxoG, the most abundant RNA damage biomarker, is a promising target for the sensitive measurement of oxidative stress and aging-associated diseases, including neuropsychiatric disorders. Most importantly, available data suggest that RNA oxidation has important implications for various signaling pathways and gene expression regulation in aging-related diseases, highlighting the necessity of using combinations of RNA oxidation adducts in both experimental studies and clinical trials. In this review, we primarily describe evidence for the effect of oxidative stress on RNA integrity modulation and possible quality control systems. Additionally, we discuss the profiles and clinical implications of RNA oxidation products that have been under intensive investigation in several aging-associated medical disorders.

Abstract
Insecticides, a heterogeneous group of chemicals, are widely used in agriculture and household practices to avoid insect-inflicted damage. Extensive use of insecticides has contributed substantially to agricultural production and the prevention of deadly diseases by destroying their vectors. On the contrary, many of the insecticides are associated with several adverse health effects like neurological and psychological diseases, metabolic disorders, hormonal imbalance, and even cancer in non-target species, including humans. Reproduction, a very selective process that ensures the continuity of species, is affected to a greater extent by the rampant use of insecticides. In females, exposure to insecticides leads to reproductive incapacitation primarily through disturbances in ovarian physiology. Disturbed ovarian activities encompass the alterations in hormone synthesis, follicular maturation, ovulation process, and ovarian cycle, which eventually lead to decline in fertility, prolonged time-to-conceive, spontaneous abortion, stillbirths, and developmental defects. Insecticide-induced ovarian toxicity is effectuated by endocrine disruption and oxidative stress. Oxidative stress, which occurs due to suppression of antioxidant defense system, and upsurge of reactive oxygen and nitrogen species, potentiates DNA damage and expression of apoptotic and inflammatory markers. Insecticide exposure, in part, is responsible for ovarian malfunctioning through disruption of hypothalamic-pituitary-gonadal axis. The current article is focused on the adverse effects of insecticides on ovarian functioning, and consequently, on the reproductive efficacy of females. The possible strategies to combat insecticide-induced toxicity are also discussed in the latter part of this review. Environ. Mol. Mutagen. 61:369-392, 2020. © 2020 Wiley Periodicals, Inc.

Abstract
Objective Polycystic ovarian syndrome (PCOS) is characterized by hormonal imbalance, oxidative stress and chronic
anovulation. The present study was designed to assess ameliorative effect of auto-locating platelet-rich plasma (PRP),
as a novel method, for inhibiting PCOS-induced pathogenesis in experimentally-induced hyperandrogenic PCOS.
Materials and Methods In this experimental study, 30 immature (21 days old) female rats were assigned into five
groups, including control (sampled after 30 days with no treatment), 15 and 30 days PCOS-sole-induced as well as
15 and 30 days PRP auto-located PCOS-induced groups. Serum levels of estrogen, progesterone, androstenedione,
testosterone, follicle stimulating hormone (FSH), luteinizing hormone (LH), ovarian total antioxidant capacity (TAC),
malondialdehyde (MDA), glutathione peroxidase (GSH-px) and superoxide dismutase (SOD) were evaluated.
Expression of estrogen receptor α (Erα), β (Erβ) and c-Myc were assessed. Finally, the numbers of intact follicles per
ovary and mRNA damage ratio were analyzed.
Results PRP groups significantly (P<0.05) decreased serum levels of FSH, LH, testosterone and androstenedione
and remarkably (P<0.05) increased estrogen and progesterone syntheses versus PCOS-sole groups. The PRP
auto-located animals exhibited increased TAC, GSH-px and SOD levels, while they showed diminished MDA content
(P<0.05) versus PCOS-sole groups. The PRP auto-located groups exhibited an elevated expression of Erα and Erβ
versus PCOS-sole groups. Moreover, PRP groups significantly (P<0.05) decreased c-Myc expression and mRNA
damage compared to PCOS-sole groups, and remarkably improved follicular growth.
Conclusion PRP is able to regulate hormonal interaction, improve the ovarian antioxidant potential as well as folliculogenesis
and its auto-location could be considered as a novel method to prevent/ameliorate PCOS-induced pathogenesis.

Abstract
This study aimed to verify whether Olea europaea L. (olive) oil (OEO) exerted a protective effect against oxidative stress induced by deltamethrin (DM) and alterations of pituitary, thyroid and gonadal hormones in adult female rats. DM (0,00256 g/kg body weight),OEO (0,6 g/kg body weight) and DM with OEO were administered to rats orally for 28 days. Volatile compounds present in olive oil were analysed by GC-MS. Estradiol (E2), Thyroxine (T4),Thyroid Stimulating Hormone (TSH), Triiodothyronine (T3), Follicle Stimulating Hormone (FSH), Luteinizing Hormone (LH), Progesterone (Pg) were measured in serum using Chemiluminescent Microparticle Immunoassay (CMIA). Lipid peroxidation (LPO), protein carbonyls (PCs), reduced glutathione (GSH) levels along with superoxide dismutase (SOD), catalase (CAT), glutathione-S-transferase (GST) and glutathione peroxidase (GPx) activities were determined in thyroid and ovarian tissues. Sesquiterpenes, (E,E)-α-farnesene (16.45%) and α-copaene (9,86%), were analysed as the main volatile compounds of OEO. The relative weight of ovaries and thyroid and body weight significantly decreased in rats treated with DM. DM caused significant alterations in TSH, T4, FSH, Pg and E2 levels while T3 and LH concentrations remained unchanged when compared to control. DM also increased significantly LPO and PCs levels. In addition, GSH reserves as well as CAT, GPx, SOD and GST activities were suppressed in DM-received rats. The presence of OEO with DM returned the levels of oxidative stress markers, thyroid and reproductive hormones at the control values. Our results indicate that OEO is a powerful agent able to protect against DM oxidative stress and endocrine changes.

Abstract
AIMS This is a follow-up study based on the results of our previous article, to further explore the effect of the TP53 codon 72 (rs1042522) and MDM2 SNP309 (rs2279744) polymorphisms on basal follicle-stimulating hormone (FSH)/luteinizing hormone (LH) ratios in infertility women. MATERIALS AND METHODS The distribution of two genetic polymorphisms (rs1042522 and rs2279744) and basal FSH/LH ratios were tested and analyzed in 1051 in vitro fertilization (IVF) patients at a university-affiliated hospital. RESULTS The TP53 codon 72 polymorphism had a significant association with the FSH/LH ratio (group I: FSH/LH <2.3 and group II: FSH/LH ≥2.3) (C/C vs. G/G: odds ratio [OR] = 1.69, 95% confidence interval [CI]: 1.07-2.65, p = 0.02; G/C vs. G/G: OR = 1.86, 95% CI: 1.25-2.77, p = 0.002). In a stratification analysis, C allele carriers and the C/C genotype showed a strong association with positive clinical pregnancy outcomes after IVF compared with G allele carriers and the G/G genotype in the recessive, dominant, and allelic genetic models in group I (C/C vs. G/G: OR = 1.84, 95% CI: 1.25-2.69, p = 0.01; C/C vs. G carrier: OR = 1.52, 95% CI: 1.12-2.07, p = 0.01; C carrier vs. G/G: OR = 1.46, 95% CI: 1.07-2.01, p = 0.02; C allele vs. G allele: OR = 1.34, 95% CI: 1.11-1.62, p = 0.003), no significant associations by stratification were observed for group II. No associations were found between MDM2 SNP309 and either of two groups. CONCLUSION The TP53 codon 72 polymorphism is associated with FSH/LH ratios, suggesting that it is a potential predictive genetic marker of IVF outcome in patients younger than 35 years of age with baseline FSH levels below 10 IU/L and who have an FSH/LH ratio <2.3.

Abstract
This study was done in order to determine the molecular and biochemical alterations following testicular torsion (TT) and torsion-reperfusion (TR). For this purpose, 54 male Wistar rats were divided into five groups as control group (n = 6) and experimental group subjected to 1, 2, 4, and 8 h unilateral left torsion induction (n = 12 in each group). After induction of TT, testicular samples were collected from each group (n = 6), and the other six rats of each group underwent the same period of reperfusion after TT and then were sampled. Histological changes, the mRNA and protein expression of heat shock protein-70 (Hsp70), and caspase-3 were examined using reverse transcriptase-PCR (RT-PCR) and immunohistochemistry, respectively. Testicular total antioxidant capacity (TAC), glutathione peroxidase (GSH-px), and malondialdehyde (MDA) levels were evaluated. The mRNA damage and DNA fragmentation were assessed. The TT and TR significantly reduced differentiation and spermiogenesis indices (p < 0.05). The TT- and TR-induced groups exhibited a severe reduction in Hsp70 expression as well as remarkable enhancement in caspase-3 expression. The TAC and GSH-px levels were decreased and the MDA content was increased in TT- and TR-induced groups. Finally, the TT and TR enhanced mRNA damage and DNA fragmentation. The TT- and TR-induced damaging oxidative stress, diminished Hsp70 expression, and enhanced caspase-3 mRNA and protein levels result in apoptosis following 1, 2, and 4 h. Whereas, following 8 h, TT and TR initiate the necrosis by inducing energy depletion as well as severe mRNA damage.

Abstract
Pyrethroids are a class of widely used insecticides. Female animal studies suggested that pyrethroid exposure impaired ovarian function, which resulted in similar symptoms of primary ovarian insufficiency (POI). However, it is still unknown whether this association applies to women. In this case-control study, a total of 172 POI patients and 247 control women were recruited in Zhejiang, China. The urinary concentrations of metabolites of pyrethroids, 3-phenoxybenzoic acid (3-PBA) and 4-fluoro-3-phenoxybenzoic acid (4-F-3-PBA), as well as the serum concentrations of follicle-stimulating hormone (FSH), luteinizing hormone (LH) and anti-Mullerian hormone (AMH) were determined. The associations of pyrethroid metabolites with POI and POI-related hormones were accessed using unconditional logistic regression. Higher urinary levels of 3-PBA were significantly associated with increased risk of POI [adjusted odds ratio (OR) = 2.344, 95% CI: 1.193-4.607 for the highest vs lowest quartile of 3-PBA, p = 0.013]. Stratified analyses showed that each log increase in urinary 3-PBA concentration was significantly associated with an induction in odds of 51.0% being in the highest quartile of FSH and 28.6% being in the highest quartile of LH levels, whereas a 25.9% reduction in odds of being in the highest quartile of AMH levels (All p for trend <0.05). To our knowledge, this is the first case-control study to report an association of pyrethroid exposure with increased risk of POI in women.

Effect of beta-cypermethrin exposure on embryo implantation in mice. Reprod Toxicol 2017; 76:1-11. [PMID: 29253587 DOI: 10.1016/j.reprotox.2017.12.001] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2017] [Revised: 10/27/2017] [Accepted: 12/04/2017] [Indexed: 02/01/2023]
Abstract
The aim of this study was to investigate the effect of β-CP on embryo implantation in mice. Forty female mice were randomly assigned to four groups of 10 mice each: one control group and three β-CP treated groups. The control group was administered corn oil only, while the three β-CP-treated groups were given corn oil containing 5, 10, and 20 mg/kg bw d β-CP for 3 months through intragastric administration. The results indicated that the administration of β-CP decreased the rate of embryo implantation (all p < 0.05), E2 level in the serum, and the expression of Homeobox A10 (HoxA10) protein. In addition, β-CP significantly increased ERa and PRA protein expression levels. These results suggest that β-CP can disrupt the balance of E2 and P, influence ERa and PRA expression and their downstream-related molecule Hoxa10, and decrease embryo implantation.
