AQUATIC TOXICOLOGY (AMSTERDAM, NETHERLANDS) 2024; 276:107090. [PMID: 39277993 DOI: 10.1016/j.aquatox.2024.107090] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/20/2024] [Revised: 08/26/2024] [Accepted: 09/09/2024] [Indexed: 09/17/2024]
Abstract
This study evaluates the impact of environmentally relevant, low-concentration deltamethrin exposure to Eriocheir sinensis ovaries. Our findings revealed that even at a concentration of 0.05 µg/L, deltamethrin exposure can induce significant ovarian toxicity through a 5-day exposure, with gradual amplification detected with time, demonstrating the toxicity amplification effect. Hematoxylin and Eosin staining revealed that low-concentration deltamethrin exposure produces pathological damage consistent with acute toxicity-yolk granules were dissolved and oocyte membranes were ruptured. High-throughput RNA-sequencing data indicated that the acute and low-concentration exposure groups involved completely different pathways and molecular functions, suggesting distinct mechanisms for their toxic effects. Following the identification of phospholipase D (PLD) as a potential core factor regulating the toxicity amplification effect of low concentration deltamethrin, we delved into subsequent mechanism studies using quantitative real-time PCR, immunofluorescence and enzyme-linked immunosorbent assay. Through the GnRH signaling pathway, increased PLD indirectly stimulates augmented estradiol secretion, subsequently inducing apoptosis by upregulating Cathepsin D, which can activate the key executioners of apoptosis-caspases (CASP3 and CASP7). In conclusion, low-concentration deltamethrin exposures can induce significant ovarian damage through apoptosis mediated by the upregulation of PLD in the ovaries of Eriocheir sinensis at environmentally relevant concentrations, which lays the preliminary theoretical groundwork for further elucidating the mechanism of toxicity amplification effect of pesticide exposure at low concentrations.

Quercetin ameliorates oxidative stress-induced apoptosis of granulosa cells in dairy cow follicular cysts by activating autophagy via the SIRT1/ROS/AMPK signaling pathway. J Anim Sci Biotechnol 2024; 15:119. [PMID: 39232832 PMCID: PMC11375867 DOI: 10.1186/s40104-024-01078-5] [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: 04/18/2024] [Accepted: 07/14/2024] [Indexed: 09/06/2024] Open
Abstract
BACKGROUND Follicular cysts contribute significantly to reproductive loss in high-yield dairy cows. This results from the death of follicular granulosa cells (GCs) caused by oxidative stress. Quercetin is known to have significant antioxidant and anti-apoptotic effects. However, the effect of quercetin on follicular cysts has yet been elucidated. Therefore, this study aimed to explore the anti-oxidant and anti-apoptosis effects and potential molecular mechanisms of quercetin in H2O2-induced primary cow GCs and 3-nitropropionic acid (3-NPA)-induced mouse model of oxidative stress and thus treat ovarian cysts in dairy cows. RESULTS In this study, compared with estrus cows, cows with follicular cysts showed heightened levels of oxidative stress and increased follicular cell apoptosis, while autophagy levels were reduced. A model of oxidative stress was induced in vitro by H2O2 and showed significant increases in apoptosis together with reduced autophagy. These effects were significantly ameliorated by quercetin. Effects similar to those of quercetin were observed after treatment of cells with the reactive oxygen species (ROS) inhibitor N-acetylcysteine (NAC). Further investigations using chloroquine (autophagy inhibitor), rapamycin (autophagy activator), selisistat (SIRT1 inhibitor), and compound C (AMPK inhibitor) showed that chloroquine counteracted the effects of quercetin on oxidative stress-induced apoptosis, while rapamycin had the same effect as quercetin. In addition, the SIRT1/AMPK pathway inhibitors antagonized quercetin-mediated mitigation of the effects of oxidative stress on increased apoptosis and reduced autophagy. Consistent with the results in vitro, in mouse ovarian oxidative stress model induced by 3-NPA, quercetin activated autophagy through the SIRT1/AMPK signaling pathway, while alleviating oxidative stress damage and inhibiting apoptosis in mouse ovaries. CONCLUSIONS These findings indicate that quercetin can inhibit apoptosis in GCs and restore ovarian function by activating autophagy through the SIRT1/ROS/AMPK signaling pathway, suggesting a new direction for the treatment of ovarian follicular cysts in high-yield dairy cows.

Abstract
Vitamin D (VD) deficiency plays an important role in the occurrence and development of various uterine diseases. At present, most studies on the mechanism of VD in the Wnt signaling pathway focus on cancer, while there are no relevant reports on its mechanism in endometritis. This study investigated the effect of vitamin D3 (VD3) on the Wnt signaling pathway in endometrial epithelial cells (BEECs) induced by lipopolysaccharide (LPS). BEECs obtained from bovine uteri were treated with VD3 (0, 50 ng/mL) and LPS (0, 10, 100 ng/mL) separately or in combination, and treated with the Wnt signaling pathway inhibitor IWR-1 to study the mechanism of action. The proliferation of BEECs was evaluated by a CCK-8 assay. qRT-PCR was used to assess the gene expression of Wnt pathway-related factors, including MYC, PCNA, LGR5, GREM1, β-catenin, FZD7, FZD2, Wnt4 and VDR. The results showed that VD3 had no significant effect on cell proliferation (P > 0.05); LPS inhibited BEEC proliferation in a time- and dose-dependent manner, and cells treated with LPS at different concentrations for 24-48 h in combination with VD3 promoted cell proliferation to varying degrees. IWR-1 inhibited cell proliferation in a time- and concentration-dependent manner, while LPS + IWR-1 treatment also significantly promoted cell proliferation after VD3 treatment (P < 0.01). The qRT-PCR results showed that the expression of Wnt4 and PCNA genes showed different trends with different LPS concentrations for stimulation, and the expression of the MYC and GREM1 genes was only stimulated by high-dose (100 ng/mL) LPS stimulation. The expression of FZD7, LGR5, FZD2 and β-catenin was upregulated by LPS at both concentrations. LPS + VD3 significantly downregulated the expression of the Wnt pathway-related genes MYC, PCNA, LGR5, GREM1 and β-catenin (P < 0.001), Wnt4 and FZD2 (P < 0.01), and significantly upregulated the expression of VDR (P < 0.05). After LPS + IWR-1 treatment, the expression of the β-catenin (P < 0.01) and LGR5 (P < 0.05) genes was significantly downregulated, while the Wnt4 (P < 0.01) and VDR (P < 0.001) genes were significantly upregulated, MYC was downregulated but without a significant difference (P > 0.05). In conclusion, VD3 treatment can mitigate the LPS-induced abnormal expression of Wnt signaling pathway genes in BEECs, showing that the Wnt pathway may be a protective pathway of VD3 against LPS-induced gene overexpression in BEECs. The results suggest that VD3 may play a regulatory role in pathways other than the Wnt signaling pathway. Whether VD3 affects the Wnt signaling pathway by affecting Wnt4 gene expression requires further study.

Endocrinology 2022; 163:6750033. [PMID: 36201606 PMCID: PMC9598563 DOI: 10.1210/endocr/bqac161] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/24/2022] [Indexed: 11/19/2022]
Abstract
Follicle-stimulating hormone (FSH) is a key endocrine regulator of ovarian function. FSH is secreted as 2 macroglycosylation variants: partially glycosylated FSH (FSH21/18) and fully glycosylated FSH (FSH24). FSH21/18 is more potent than FSH24 at binding to and activating the FSH receptor (R). The ratio of FSH21/18:FSH24 has been shown to change with age, with FSH21/18 predominant at reproductive prime, and FSH24 predominant during perimenopause/menopause. How these FSH glycosylation variants modulate ovarian follicle functions remains largely unknown. The aim of this study was to investigate the effect of FSH glycosylation variants of pre-antral follicle function. Pre-antral follicles were isolated from 3- to 5-week-old C57BL/6 mice and treated ±10 ng/mL FSH21/18, FSH24, a ratio of 80:20 FSH21/18:FSH24 (to mimic reproductive prime), 50:50 FSH21/18:FSH24 (perimenopause), or 20:80 FSH21/18:FSH24 (menopause) for up to 96 hours. FSH21/18 and 80:20 FSH21/18:FSH24 increased follicle growth, in comparison with control, contrasting with FSH24 and 20:80 FSH21/18:FSH24. Survival rates were decreased in follicles treated with FSH24 or 20:80 FSH21/18:FSH24, with follicles undergoing basement membrane rupture and oocyte extrusion, increased Caspase3 gene and protein expression, and decreased markers of cell proliferation in FSH24 or 20:80 FSH21/18:FSH24-treated follicles. Moreover, this correlated with differential regulation of key genes modulating follicular functions. Pharmacological inhibitors of key FSH signal pathways suggests FSH21/18 and FSH24 initiate different FSHR signal pathway activation, which may determine their differential effects on follicle growth and survival. These data suggest that the nature of FSH glycosylation modulates the follicular cellular environment to regulate follicle growth and survival and may underpin the increasing ovarian resistance to FSH observed during aging.
