Exposure to Titanium Dioxide Nanoparticles Leads to Specific Disorders of Spermatid Elongation via Multiple Metabolic Pathways in Drosophila Testes. ACS OMEGA 2024; 9:23613-23623. [PMID: 38854533 PMCID: PMC11154731 DOI: 10.1021/acsomega.4c01140] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/04/2024] [Revised: 05/10/2024] [Accepted: 05/14/2024] [Indexed: 06/11/2024]
Abstract
Titanium dioxide nanoparticles (TiO2 NPs) have been extensively utilized in various applications. However, the regulatory mechanism behind the reproductive toxicity induced by TiO2 NP exposure remains largely elusive. In this study, we employed a Drosophila model to assess potential testicular injuries during spermatogenesis and conducted bulk RNA-Seq analysis to elucidate the underlying mechanisms. Our results reveal that while prolonged exposure to lower concentrations of TiO2 NPs (0.45 mg/mL) for 30 days did not manifest reproductive toxicity, exposure at concentrations of 0.9 and 1.8 mg/mL significantly impaired spermatid elongation in Drosophila testes. Notably, bulk RNA-seq analysis revealed that TiO2 NP exposure affected multiple metabolic pathways including carbohydrate metabolism and cytochrome P450. Importantly, the intervention of glutathione (GSH) significantly protected against reproductive toxicity induced by TiO2 NP exposure, as it restored the number of Orb-positive spermatid clusters in Drosophila testes. Our study provides novel insights into the specific detrimental effects of TiO2 NP exposure on spermatid elongation through multiple metabolic alterations in Drosophila testes and highlights the protective role of GSH in countering this toxicity.

Reprod Domest Anim 2024; 59:e14595. [PMID: 38773768 DOI: 10.1111/rda.14595] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2024] [Revised: 04/10/2024] [Accepted: 04/28/2024] [Indexed: 05/24/2024]
Abstract
Oocyte maturation involves both nuclear and cytoplasmic maturation. Mogroside V (MV) has been shown to enhance nuclear maturation, mitochondrial content, and developmental potential of porcine oocyte during in vitro maturation (IVM). However, the impact of MV on cytoplasmic maturation and its underlying mechanisms are not understood. This study aimed to assess the effect of MV on cytoplasmic maturation. Germinal vesicle (GV) oocytes treated with MV exhibited a noticeable increase in cortical granules (CGs) formation. Additionally, MV enhanced the expression of NNAT and improved glucose uptake in mature oocytes. Further insights were gained through Smart-seq2 analysis of RNA isolated from 100 oocytes. A total of 11,274 and 11,185 transcripts were identified in oocytes treated with and without MV, respectively. Among quantified genes, 438 differentially expressed genes (DEGs) were identified for further analysis. Gene Ontology (GO) enrichment analysis indicated that these DEGs were primarily involved in DNA repair regulation, cellular response to DNA damage, intracellular components, and organelles. Furthermore, the DEGs were significantly enriched in three KEGG pathways: fatty acid synthesis, pyruvate metabolism, and WNT signalling. To validate the results, lipid droplets (LD) and triglyceride (TG) were examined. MV led to an increase in the accumulation of LD and TG production in mature oocytes. These findings suggest that MV enhances cytoplasmic maturation by promoting lipid droplet synthesis. Overall, this study provides valuable insights into the mechanisms through which MV improves oocyte quality during IVM. The results have significant implications for research in livestock reproduction and offer guidance for future studies in this field.

[PMID: 38244353 DOI: 10.1016/j.theriogenology.2024.01.008] [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: 09/27/2023] [Revised: 01/05/2024] [Accepted: 01/06/2024] [Indexed: 01/22/2024]
Abstract
Heat stress (HS) is a stressor that negatively affect female reproduction. Specially, oocytes are very sensitive to HS. It has been demonstrated that some active compounds can protect oocyte from HS. We previously found that Mogroside V (MV), extracted from Siraitia grosvenorii (Luo Han Guo), can protect oocyte from many kinds of stresses. However, how MV alleviates HS-induced disruption of oocyte maturation remains unknown. In this study, we treated the HS-induced porcine oocytes with MV to examine their maturation and quality. Our findings demonstrate that MV can effectively alleviate HS-induced porcine oocyte abnormal cumulus cell expansion, decrease of first polar body extrusion rate, spindle assembly and chromosome separation abnormalities, indicating MV attenuates oocyte mature defects. We further observed that MV can effectively alleviate HS-induced cortical granule distribution abnormality and decrease of blastocyst formation rate after parthenogenesis activation. In addition, MV treatment reversed mitochondrial dysfunction and lipid droplet content decrease, reduced reactive oxygen species levels, early apoptosis and DNA damage in porcine oocytes after HS. Collectively, this study suggests that MV can effectively protect porcine oocytes from HS.

Abstract
Siraitia grosvenorii (SG) is an edible medicinal plant found mainly in Guangxi, China, and Mogroside V (MGV) is the main component of SG extract. Previous research has shown that SG and MGV exert anti-inflammatory, antioxidative and neuroprotective effects. However, it is not clear whether MGV has anti-depression-like effect. In this study, we evaluated the neuroprotective effects and anti-depression-like effect of MGV both in vitro and in vivo. By performing in vitro tests, we evaluated the protective effects of MGV on PC12 cells with corticosterone-induced injury. In vivo tests, we used the chronic unpredictable mild stress (CUMS) depression model. Fluoxetine (10 mg/kg/day) and MGV (10 or 30 mg/kg/day) were administered by gavage for 21 days, and the open field test (OFT), novelty suppressed feeding test (NSFT), Tail suspension test (TST), and forced Swimming test (FST) were used to evaluate the depressive-like behaviors. In addition, we investigated the role of proinflammatory cytokines (IL-1β, IL-6, and TNF-α) and anti-inflammatory cytokine (IL-4) in the hippocampal and cortex tissues. The levels of Superoxide dismutase (SOD), malondialdehyde (MDA), and glutathione peroxidase (GSH-PX) in hippocampal and cortex tissues were also measured. Pathological changes in the hippocampal dentate gyrus and cortex regions were detected by immunofluorescence and Western blotting was used to measure the protein expression of BDNF, TrkB, TNF-α, and AKT. The results showed that MGV had a protective effect on PC12 cells with corticosterone-induced incurred injury. In addition, MGV treatment relieved the depressive symptoms and significantly reduced inflammatory levels (IL-1β, IL-6, and TNF-α). MGV also significantly reduced oxidative stress damage and reduced the levels of apoptosis in hippocampal nerve cells. These results suggested that the anti-depressive effect of MGV may occur through the inhibition of inflammatory and oxidative stress pathways and the BDNF/TrkB/AKT pathway. These findings provide a new concept for the identification of new anti-depressive strategies.

Reprod Toxicol 2023; 115:85-93. [PMID: 36549457 DOI: 10.1016/j.reprotox.2022.12.005] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2022] [Revised: 11/27/2022] [Accepted: 12/12/2022] [Indexed: 12/24/2022]
Abstract
Lipopolysaccharide (LPS), a significant virulence factor of gram-negative bacteria, adversely affects female reproduction, especially the maturation and early embryonic development of oocytes, through inducing of inflammatory and oxidative stress-associated toxic responses. Resveratrol (Res), a potent antioxidant, exhibits many beneficial effects on the maturation and developmental competence of oocytes. However, it is unclear whether Res can restore LPS-induced defects in the maturation of oocytes during meiosis. In this study, we used porcine oocytes to explore the protective effects of Res and its underlying mechanism against the toxic impacts of LPS exposure on meiotic maturation and developmental competence of oocytes during meiosis. The oocytes were randomly assigned to a control, LPS-exposed or Res-supplemented group. Nuclear and cytoplasmic maturation was assessed after 26 h (MI) or 44 h (MII) of in vitro maturation (IVM). Our results showed that 10 µM Res significantly improved the rates of oocyte maturation and blastocyst formation after exposure to 15 µg/mL LPS. In addition, Res preserved the normal spindle/chromosome structure and maintained acetylated tubulin levels, actin polymerization and cortical granules (CGs) distribution. Additionally, Res protected mitochondrial content and function, scavenges reactive oxygen species (ROS), and reduced DNA damage and apoptosis in LPS-exposed oocytes. Furthermore, inhibition of SIRT1 by its specific inhibitor EX527 suppressed the recovery of ROS levels, mitochondrial content, and spindle/chromosome structure by Res supplementation. In summary, this study shows that Res can alleviate the impacts of LPS-induced toxicity on meiosis in porcine oocytes by upregulating SIRT1, which ameliorates oxidative stress and increasing mitochondrial content.
