Abstract
Bisphenol AF (BPAF) is increasingly used and now found in products intended for human consumption. The protective effect of 1,8-cineole (CIN) against BPAF-induced reproductive toxicity was investigated. Four groups were created, with each group consisting of eight rats: control, BPAF (200 mg/kg), CIN (200 mg/kg), and BPAF + CIN groups. The results demonstrated that the BPAF group exhibited a decline in testosterone levels and a decrease in sperm parameters compared with the control. Additionally, higher levels of MDA were observed, along with lower levels of GSH and GPx activity. CAT activity also decreased slightly. Tnf-α, Nf-κB levels were significantly higher, and caspase-3 expression was elevated, while PCNA expression decreased. BPAF significantly increased tissue degeneration compared with the control. However, the BPAF + CIN group showed statistically significant improvements in sperm parameters, except for concentration. They also exhibited an increase in testosterone levels and an improvement in MDA and GSH levels compared with the BPAF group. However, GPx activity partially enhanced. Tnf-α and Nf-κB levels were significantly reduced, and caspase-3 levels declined while PCNA and Bcl-2 levels increased. The Johnsen Testicular Biopsy score showed a substantial increase. Overall, these results suggest that CIN co-treatment in rats enhanced reproductive health and exhibited antioxidant, antiapoptotic, and anti-inflammatory properties against BPAF-induced testicular damage.

Tissue Cell 2024; 89:102459. [PMID: 39002290 DOI: 10.1016/j.tice.2024.102459] [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: 03/15/2024] [Revised: 06/04/2024] [Accepted: 07/01/2024] [Indexed: 07/15/2024]
Abstract
Testicular torsion is an urological emergency and can lead to ischemia damage and testicular loss if not diagnosed in time. Proanthocyanidin is reported to have anti-inflammatory and antioxidant properties. The current study aimed to examine the possible effects of proanthocyanidin (P) on the testis in torsion/detorsion (T/D)-induced testicular ischemia/reperfusion (I/R) injury in rats. Forty rats were divided into four groups (n=10 for each): sham-operated (sham), I/R, I/R + P100 (100 mg/kg, 30 min before torsion), and I/R + P200 (200 mg/kg, 30 min before torsion). Testicular T/D was performed on the left testicle by 3 hours of torsion at 720° clockwise, followed by 3 hours of detorsion. In the I/R group, an increase in malondialdehyde (MDA) levels and a decrease in glutathione (GSH), vitamin C (Vit C), glutathione peroxidase (GPx), glucose-6-phosphate dehydrogenase (G6PD) values were determined compared to the sham group (p<0.001). Moreover, an increase in the expression of cleaved caspase-3 and Bcl2-associated X protein (Bax), a decrease in the expression of B-cell lymphoma 2 (Bcl-2) and proliferating cell nuclear antigen (PCNA) were detected in the I/R group (p<0.001). Histopathologically, it was determined that the Johnsen and Cosentino scores of the testicles were irregular in the I/R group (p<0.001). Proanthocyanidin treatment caused a decrease in MDA, cleaved caspase-3 and Bax levels and an increase in GSH, Vit C, GPx, G6PD, Bcl-2 and PCNA values. Additionally, Johnsen and Cosentino rearranged the scores. The present findings revealed the protective and curative effects of proanthocyanidin in organ damage due to testicular torsion/detorsion-induced ischemia/reperfusion with their antioxidative and antiapoptotic properties.

Characterisation of bioactive compounds from leaves of Smilax fluminensis Steud. by gc-MS and LC-DAD-MS, and analysis of its antioxidant and ecotoxicological activities. Nat Prod Res 2024:1-9. [PMID: 38425178 DOI: 10.1080/14786419.2024.2324375] [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: 10/24/2023] [Accepted: 02/22/2024] [Indexed: 03/02/2024]
Abstract
Smilax fluminensis Steud. is distributed in Central and South America, commonly named as 'salsaparilha' or 'japicanga'. In the present work, the chemical composition was determined, antioxidant and cytotoxic effects were evaluated for the ethanol extract (EE) and fractions from leaves. Fatty acid esters and phytol were characterised in the hexane (HEX) fraction. O-glycosylated flavonols and flavones, caffeic acid derivatives, and steroidal saponins were annotated for EE, and dichloromethane (DCM), ethyl acetate (AC), and hydroethanol (HE) fractions. The samples contain flavonoids and phenolic compounds, and the AC fraction displayed the biggest concentration of these substances. Antioxidant potential was observed in all samples, being especially pronounced in the AC fraction by DPPH and FRAP assays, with IC50 values of 8.18 and 2.35 µg/mL, respectively. AC and HEX fractions showed 35% and 5% lethality at 1000 μg/mL, in the Artemia salina assay, and the other samples did not show a toxic effect.

[PMID: 38318031 PMCID: PMC10839873 DOI: 10.1016/j.heliyon.2024.e24579] [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] [Received: 08/04/2023] [Revised: 12/29/2023] [Accepted: 01/10/2024] [Indexed: 02/07/2024] Open
Abstract
Aims Heme oxygenase (HO-1) affords protection against ischaemia/reperfusion (I/R) injury; however, its effects on testicular I/R injury remain poorly explored. Herein, we aimed to examine the effects of HO-1 on testicular I/R injury and elucidate the underlying mechanism. Methods Using the TALEN technique, we knocked out the HO-1 gene from rats. In vivo: Thirty hmox+/+ and 30 hmox-/- rats were randomly assigned to six groups: sham-operated (sham), I/R (the left testicle torsion/detorsion) 0 d,I/R 1d, I/R 3d, I/R 7d and I/R 28d. In vitro: GC-1 were suffered from: control,H/R (oxygen-deprivation/reoxygenation),H/R + HO-1 siRNA,H/R + c-Jun siRNA or H/R + HO-1 siRNA + c-jun.We performed immunofluorescence and immunohistochemistry experiments to detect HO-1 nuclear translocation. Flow cytometry was used to detect cell apoptosis and analyse the cell cycle. High-resolution miRNA, mRNA sequencing, reverse transcription-quantitative PCR, and western blotting were performed to identify testicular I/R injury-related genes strongly conserved in HO-1 knockout rats. A double luciferase reporter assay was performed to verify the relationship between C-jun and miR-221/222. Main findings In vivo, HO-1 improved the pathological damage induced by testicular I/R. In GC-1 cells, we confirmed the nuclear translocation of HO-1 and its protective effect against hypoxia/reoxygenation (H/R) damage. Accordingly, HO-1 protein itself, rather than heme metabolites, might play a key role in testicular I/R. Gene sequencing was performed to screen for miR221/222 and its downstream gene, thymocyte selection-associated high mobility group box (TOX). HO-1 increased c-Jun phosphorylation in the H/R group, knocked down c-Jun in GC-1 cells, and decreased miR-221/222 expression. Inhibition of HO-1 expression decreased the expression of c-Jun and miR-221/222, which was rescued by adding c-Jun. Dual-luciferase reporter assay confirmed the interaction between c-Jun and miR-221/222. Conclusions HO-1 could exert a protective effect against testicular I/R via the phosphorylated c-Jun-miR-221/222-TOX pathway.

Abstract
Bisphenol AF (BPAF) is an endocrine disruptor, and human exposure to these chemicals is growing in industrialized nations. BPAF has been demonstrated in studies to have toxic effects on reproductive health. This study examined the effects of oral exposure to BPAF on the reproductive system and the protective effects of carvacrol in rats. From 32 Wistar albino rats, four separate groups were set up for this purpose. Carvacrol 75 mg/kg and BPAF 200 mg/kg were administered by oral gavage method. Rat sperm parameters and serum testosterone levels were measured after 28 days of administration. The study looked at the MDA in the testis tissues, as well as CAT, GPx, and GSH as antioxidants parameters, NF-κB and TNF-α as inflammatory markers, caspase-3 and Bcl-2 as apoptosis parameters, and PCNA as cell proliferation markers. In addition, testis tissues underwent histological evaluation. As a result, in rats exposed to only BPAF, sperm counts declined, testosterone levels reduced, oxidative stress, inflammation, and apoptosis increased, and cell proliferation decreased. Furthermore, severe disruptions in tissue architecture and decreased spermatogenesis were reported. In contrast, sperm parameters improved, testosterone levels increased, oxidative stress and inflammation decreased, and apoptosis was prevented in the carvacrol-treated group compared to the BPAF-only group. It was also found that spermatogenesis was maintained, and structural abnormalities in testicular tissue were mostly avoided with an increase in PCNA expression. According to the findings, despite BPAF-induced testicular and reproductive toxicity, carvacrol had therapeutic potential due to its anti-inflammatory, antioxidant, cell proliferation-increasing, and anti-apoptotic activities.

Abstract
Background Bisphenol A (BPA), an endocrine-disrupting chemical (EDC), is ubiquitous in our environment and poses a significant threat to male fertility. Date seeds (DSs) are used in folk medicine due to their antioxidant activity. Aim The purpose of this study was to assess the beneficial effects of DSs, whether in powder or nanoparticle form, against BPA-induced testicular oxidative challenges and apoptosis, aided by inspection of specific genes linked to fertility, oxidative stress and intrinsic mitochondrial pathway of apoptosis. Methods Thirty-five adult male albino rats were equally divided into 5 groups including control, BPA, BPA + date seeds powder "DSP", BPA + date seed nanoparticle 1/10 (DSNP 1/10) and BPA + DSNP 1/20 groups. Results TEM showed that the ball-mill method was effective to form DSNP with an average size of 20 nm. BPA significantly impaired sperm motility, morphology, viability and concentration. It also reduced serum testosterone levels and evoked marked oxidative stress in the testes. Additionally, serum levels of triiodothyronine and thyroxine were extremely reduced. Moreover, testicular mRNA relative expression levels of CYP11A1 and Nrf-2 were markedly downregulated. Testicular apoptosis was also promoted whereas Bax/Bcl-2 ratio was profoundly elevated. Histological pictures of the testes, epididymis, seminal vesicles and prostate confirmed the unfavorable effects of BPA. Surprisingly, we first demonstrated that DSs, specifically the nanoparticle form, strongly alleviated all of BPA's negative effects, with DSNP 1/20 achieving the best results. Conclusion Therefore, DSNP in both doses could be regarded as an ideal candidate for abating the male reproductive challenges caused by BPA.

Abstract
Increased pro-inflammatory cytokines and oxidative stress contribute to the pathophysiology of ulcerative colitis (UC). Inula viscosa is a plant with antioxidant and anti-inflammatory properties. We investigated the effect of an ethanolic extract of I. viscosa on an experimental UC model created using acetic acid. Rats were divided into four groups of eight: group 1, control; group 2, 3% acetic acid group; group 3, 100 mg/kg sulfasalazine + 3% acetic acid group; group 4, 400 mg/kg I. viscosa + 3% acetic acid. I. viscosa and sulfasalazine were administered by oral gavage and 3% acetic acid was administered per rectum. We found that I. viscosa treatment decreased colon malondialdehyde, tumor necrosis factor-α, interleukin-1 beta and nuclear factor kappa B levels; it increased reduced glutathione, nuclear factor erythroid 2-related factor 2, heme oxygenase-1 and kelch-like ECH-associated protein 1 levels and glutathione peroxidase enzyme activity. Group 1 colon exhibited normal histological structure. Slight inflammatory cell infiltration and edema and insignificant slight erosion in crypts were detected in colon tissues of group 4. We found that I. viscosa reduced oxidative stress and inflammation, which was protective against UC by inducing the Nrf-2/Keap-1/HO-1 pathway in the colon.

Abstract
(1) Background: The mammary glands of the perinatal goats are susceptible to reactive oxygen species (ROS) leading to oxidative injury. Although Dioscorea alata L. is rich in anthocyanins with high safety and excellent free-radical-scavenging ability, the effect and mechanism of Dioscorea alata L. anthocyanins (DAC) on the antioxidant capacity of the black Hainan goat has been the subject of few studies to date; (2) Methods: For this reason, feeding experiments were performed by feeding experimental diets, and the pre-protective capacity of DAC on goat mammary epithelial cells was explored on the basis of the established model of H2O2 injury; (3) Results: As well as altering rumen fermentation parameters in perinatal female goats, dietary challenge also improves antioxidant capacity in their blood and milk. thereby enhancing children's antioxidant capacity and increasing their resistance to oxidative stress. However, we also found that DAC pretreatment was capable of activating both Nrf2 and MAPK/JNK pathways, which results in enhanced antioxidase activity and elimination of ROS; (4) Conclusions: Together, these findings suggest that DAC may have a pre-protective role on perinatal Hainan black goats through the regulation of Nrf2 and MAPK/JNK pathways in GMEC.

Abstract
BACKGROUND Ischemia-reperfusion injury (IRI) is the key reason of injury after testicular torsion and may eventually lead to male infertility. Oleuropein, a natural antioxidant isolated from Olea europaea, has shown beneficial effects in different models of ischemia. We evaluated the effects of oleuropein on testicular IRI and explored the underlying protective mechanisms. METHODS A mouse testicular torsion/detorsion (T/D) model and an oxygen-glucose deprivation/reperfusion (OGD/R) germ cell model were established and treated with oleuropein. H&E staining was used to evaluate testicular pathological changes. Apoptosis and apoptosis-associated protein levels in testis tissues were assessed by TUNEL staining, immunohistochemical staining and western blot. Apoptosis levels and apoptosis-associated protein levels in GC-1 were evaluated by flow cytometry, immunofluorescence and western blot. Oxidative stress levels were assessed by malondialdehyde (MDA) and superoxide dismutase (SOD) kits. Cell viability and inflammatory protein levels were evaluated by CCK-8 assay coupled with qRT-PCR. RESULTS Relative to the control group, SOD activity was markedly suppressed, while MDA, Bax, Caspase-3, TNF-α as well as IL-1β levels were significantly increased in the T/D model and OGD/R model. However, all of the aforementioned alterations were relieved by oleuropein treatment. CONCLUSION Our findings indicate that oleuropein may be a promising treatment option to attenuate testicular IRI via its anti-oxidant, anti-inflammatory as well as anti-apoptotic properties.
