Vet Res Commun 2024; 48:1367-1377. [PMID: 38243140 DOI: 10.1007/s11259-024-10302-6] [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: 04/15/2023] [Accepted: 01/09/2024] [Indexed: 01/21/2024]
Abstract
The aim of this study was to evaluate the effects of different selenium compounds on the sperm quality of cryopreserved ram semen. Ejaculates from four rams, collected using an artificial vagina heated to 38 °C, were individually evaluated. The approved ejaculates were pooled and diluted (1:1 v:v) in Tris-egg yolk extender (20%, v/v) and separated into two control groups, one cooled for 2 h and the other for 4 h. The pooled ejaculates at the two cooling periods were supplemented with two doses (0.5 and 1 μg/mL) of organic selenium (ORG), and inorganic selenium (SeNa), each. The samples were packed in 0.25 ml straws, at a concentration of 400 × 106 sperms/mL and stored in liquid nitrogen. The straws were thawed in a water bath at 37 °C for 20 s, and the samples were subjected to sperm kinetics evaluation by Computer Assisted Semen Analysis software. Sperm membrane integrity, acrosome morphology, and mitochondrial potential were assessed. In addition, oxidative stress markers reactive oxygen species (ROS), ferric reducing antioxidant power (FRAP), thiobarbituric acid reactive species (TBARS), and glutathione peroxidase (GPx) enzyme activity) were also evaluated. No significant improvement was observed in the ram semen quality at the two cooling times. Supplementation of the freezing extender with 0.5 μg/mL ORG, subjected to 4 h cooling period, increased the sperm motility when compared with the control group at the same cooling time. In addition, the 0.5 μg/mL SeNa group, under the 2 h cooling period, showed an increase in sperm motility when compared to the control group at the same cooling period. Considering the importance of sperm motility as a fertility parameter, our study indicates that supplementation with ORG and SeNa can help improve the total motility of the cryopreserved ram semen.

Astaxanthin Improved the Quality of Hu Ram Semen by Increasing the Antioxidant Capacity and Mitochondrial Potential and Mitigating Free Radicals-Induced Oxidative Damage. Animals (Basel) 2024; 14:319. [PMID: 38275779 PMCID: PMC10812392 DOI: 10.3390/ani14020319] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2023] [Revised: 12/07/2023] [Accepted: 12/14/2023] [Indexed: 01/27/2024] Open
Abstract
The objective of this research was to investigate the effect of astaxanthin supplementations of semen extender on the quality of Hu ram semen after up to five days of preservation at 4 °C. Semen samples were collected from five healthy Hu rams using an artificial vagina during breeding season (April to August 2023) and diluted with a basic extender supplemented with control (0), 1 µM, 2 µM, 3.5 µM, or 4.5 µM of AXT. Overall, 170 semen ejaculate samples (34 repetitions) from five healthy Hu rams were used in our research study. The results revealed that the addition of AXT (3.5 µM) significantly (p ≤ 0.05) increased the sperm kinematic indexes (T.M%, P.M%, MAD%, STR%, and LIN %), sperm viability, plasma membrane integrity, acrosome integrity, total antioxidant content (T-AOC), and mitochondrial membrane potential (MMP) of the Hu rams spermatozoa after up to five days of preservation at 4 °C. Contrary to that, the addition of the best concentration of AXT (3.5 µM) to the semen extender significantly (p ≤ 0.05) reduced the reactive oxygen species (ROS) and malondialdehyde (MDA) concentration of Hu ram semen. In conclusion, the results of the current study indicate that the addition of a semen extender with AXT improves the quality of Hu ram spermatozoa by increasing the total antioxidant capacity (T-AOC) and mitochondrial membrane potential (MMP). On the other hand, reducing free radicals induced oxidative (ROS) and per oxidative (MDA) damage to Hu ram semen.

Abstract
Cryopreserved semen is widely used in assisted reproductive techniques. Post-thawing spermatozoa endure oxidative stress due to the high levels of reactive oxygen and nitrogen species, which are produced during the freezing/thawing process, and the depletion of antioxidants. To counteract this depletion, supplementation of sperm preparation medium with antioxidants has been widely applied. Melatonin is a hormone with diverse biological roles and a potent antioxidant, with an ameliorative effect on spermatozoa. In the present study, we assessed the effect of melatonin on thawed bovine spermatozoa during their handling. Cryopreserved bovine spermatozoa were thawed and incubated for 60 min in the presence or absence of 100 μΜ melatonin. Also, the effect of melatonin was assessed on spermatozoa further challenged by the addition of 100 μΜ hydrogen peroxide. Spermatozoa were evaluated in terms of kinematic parameters (CASA), viability (trypan blue staining) and antioxidant capacity (glutathione and NBT assay, determination of iNOS levels by Western blot analysis). In the presence of melatonin, spermatozoa presented better kinematic parameters, as the percentage of motile and rapid spermatozoa was higher in the melatonin group. They also presented higher viability and antioxidant status, as determined by the increased cellular glutathione levels and the decreased iNOS protein levels.

Abstract
Reactive Oxygen Species (ROS), primarily produced by cellular metabolism, are highly reactive molecules that modify cellular compounds. During sperm preparation in Assisted Reproductive Techniques (ARTs), intrinsic and extrinsic sources of ROS can impact spermatozoa's oxidative status. The modification of the media with compounds that enhance sperm quality characteristics is of great significance. The current study investigated the effect of pterostilbene, a phenolic compound, on bovine sperm quality. Cryopreserved spermatozoa from six bulls were thawed, supplemented with pterostilbene (0, 10 μΜ, 25 μΜ) and incubated for 60 min and 240 min. Spermatozoa were analyzed in terms of motility, viability, acrosomal status and intracellular concentration of superoxide anion in each time point. The incubation of spermatozoa with 25 μΜ pterostilbene resulted in the preservation of quality parameters through superoxide anion mitigation, while its presence in capacitating conditions resulted in higher percentage of acrosome-reacted spermatozoa. The results of the present study indicate that the addition of pterostilbene prevents oxidative insult to spermatozoa and preserves the sperm quality parameters.

Abstract
Reactive oxygen species (ROS) and oxidative stress (OS), the imbalance between the production of free radicals and the cellular antioxidant defenses, are discussed in relation to their role in bovine sperm physiology. Oxidative stress has been associated to male infertility and low fertility rates in Assisted Reproductive Techniques (ART). Antioxidant supplementation is an interesting approach to overcome OS-related infertility and assisted reproduction drawbacks. Several studies have been conducted to identify the potential sources of ROS in a typical ART setting and the impact of antioxidant supplementation on semen quality and pregnancy outcome. Procedures such as freezing and thawing, centrifugation and incubation are thought to produce significant amounts of ROS with a negative impact on sperm quality parameters and reproductive competence. Given the important role of ROS in sperm function, the addition of antioxidants in sperm media to prevent OS and to improve the reproductive outcome requires attention. Currently, there is limited evidence to support the ameliorative effect of antioxidant supplementation on fertilization and embryo development in farm animals. This review summarizes the different types and concentrations of antioxidants used in sperm preparation media of bovine species and their effectiveness in neutralizing excessive ROS production while preserving physiological sperm function.

Abstract
Sperm cells are particularly vulnerable to reactive oxygen species (ROS), impairing their fertilizing ability. Our objective was to study the effect of a novel mitochondrial-directed antioxidant, AntiOxBEN2, on bovine sperm function. This antioxidant was added to the semen capacitation medium (CAP), during the swim-up process, and to the fertilization medium (FERT) during the co-incubation of matured oocytes and capacitated spermatozoa, in concentrations of 0 (control), 1, and 10 µM. After the swim-up, sperm motility (CASA and visual analysis), vitality (eosin-nigrosin), mitochondrial membrane potential (JC1), intracellular ROS, adenosine triphosphate (ATP) levels, and basal metabolism (Seahorse Xfe96) were evaluated. Embryo development and quality were also assessed. Higher cleavage rates were obtained when 1 µM AntiOxBEN2 were added to CAP and FERT media (compared to control, p < 0.04). A positive effect of AntiOxBEN2 on intracellular ROS reduction (p = 0.01), on the increment of mitochondrial membrane potential (p ≤ 0.003) and, consequently, on the sperm quality was identified. However, the highest dose impaired progressive motility, ATP production, and the number of produced embryos. The results demonstrate a beneficial effect of AntiOxBEN2 (1 µM) on sperm capacitation and fertilization processes, thus improving embryonic development. This may constitute a putative novel therapeutic strategy to improve the outcomes of assisted reproductive techniques (ART).

Abstract
BACKGROUND AND OBJECTIVE Urinary tract infections (UTI) are commonly treated with broad-spectrum antibiotics, but treatment has limitation due to causes of nephrotoxicity in uroepithelial cells. Recently, the researcher focuses their research on alternative therapy for the treatment of UTI. This study evaluated the anti-infectious effect of crocetin against adherence of pathogenic [2-14 C]-acetate labeled Escherichia coli (MTCC-729) to rat proximal renal tubular cells (NRK-52E cells) and explores the possible mechanism of action. MATERIALS AND METHODS In vitro cytotoxicity and radio acetate labeled tests were performed on NRK-52E cells. The rats were divided into five different groups as follows: normal control (NC), disease control (DC), and various doses of crocetin (1.25, 2.5, and 5 mg/kg) treated group rats. White blood cells in blood, urine, and bacterial colony counts were estimated at regular intervals. Pro-inflammatory cytokines, such as interleukin-6 (IL-6), monocyte chemoattractant protein-1 (MCP-1), interleukin-10 (IL-10), and interleukin-8 (IL-8), were also estimated. In the current study, we estimated the mRNA expression of toll-like receptor-4 (TLR-4) and toll-like receptor-2 (TLR-2) in the renal and bladder tissues. RESULTS Crocetin significantly (p < .05) inhibited the adherence of E. Coli in NRK-52E cells. Crocetin suppresses the lipid peroxidation (LPO) 42% in cells treated with H2 O2 cells without crocetin. The white blood cells (WBC) count in blood and urine were augmented and crocetin treatment significantly (p < .05) reduced the WBC in urine and blood. The pro-inflammatory cytokines, such as IL-6, MCP-1, IL-10, and IL-8, significantly (p < .05) increased in the DC group and crocetin significantly (p < .05) reduced the pro-inflammatory cytokines. Dose-dependent treatment of crocetin significantly reduced the mRNA expression of TLR2 and TLR4 in the renal and bladder tissues. CONCLUSION Crocetin considerably reduced the bacterial adherence to NRK-52E cells, attenuated the H2 O2 induced toxicity in NRK-52E cells and also improved the renal tubular function, and reduced the inflammatory response via altering the inflammatory and antioxidant markers. PRACTICAL APPLICATION As we all know that urinary tract infection is the most common disease worldwide. In this study, we scrutinized the protective effect of crocetin against urinary tract infection. Crocetin treatment considerably reduced the zone of inhibition and improved radioactivity. Crocetin significantly reduced the levels of cytokines and inflammatory mediators. Crocetin can be used as a protective drug in the treatment of urinary tract infections.

Abstract
Background Asthenozoospermia is a usual male infertility factor, characterized by decreased semen quality. It has been revealed that antioxidants improve sperm function, enhance endogenous antioxidant activities, and protect spermatozoa against oxidative damage during cryopreservation. This aimed to evaluate the effects of vitamin D on sperm kinematics and apoptosis in the semen of bulls with normozoospermia and asthenozoospermia after the freeze-thaw process. For this purpose, 32 semen samples of four Holstein bulls (normozoospermic, progressive motility > 70 %) and 32 semen samples of four bull (asthenozoospermic progressive motility < 40 %) were collected and pooled separately (normozoospermic and asthenozoospermic). Samples were then diluted into four equal aliquots of extender containing different vitamin D concentrations (0, 5, 10, and 50 ng/mL) and aspirated into a 0.5 mL straw. Results The percentages of sperm progressive motility and viability were significantly higher (P < 0.05) in 50 ng/mL of vitamin D in normozoospermic group. Sperm kinematics parameters including curvilinear velocity (VCL), straight-line velocity (VSL), and average path velocity (VAP) were significantly higher in the high dose (50 ng/mL) vitamin D-treated group compared to the low dose vitamin D-treated group (5ng/mL) in normozoospermic bull semen samples. The supplementation of the semen extender with different concentrations of vitamin D could not increase the rate of acrosome integrity in normozoospermic bulls compared to the control group (P < 0.05). In the asthenozoospermic group, 10 ng/mL vitamin D-treated group could increase the rate of plasma membrane integrity compared to 5 ng/mL vitamin D-treated group (P < 0.05). The percentages of early-apoptosis (P = 0.049) and late-apoptosis (P = 0.005) were significantly higher in the asthenozoospermic than the normozoospermic group. Conclusions The present study revealed that a high dose (50 ng/mL) of vitamin D protected normozoospermic bulls’ sperms from the freezing procedure and lead to higher quality of frozen-thawed bull sperm.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Oxidative stress is one of the underlying causes of male infertility. Medicinal plants have many benefits for infertility treatment in men. AIM OF THE STUDY In the present study, we evaluated in vitro effects of Capparis spinosa leaf extract on human sperm function, DNA fragmentation, and oxidative stress. MATERIALS AND METHODS We conducted this study on the hydroalcoholic extract of C. spinosa. Polyphenol compounds and antioxidant effects of the leaf and fruit extract were determined by HPLC and DPPH method, respectively. Flavones and flavonols, total flavonoid, total phenolic content, tannin, and the total carbohydrate content were determined calorimetrically. Semen samples from 50 healthy men (20-45 years) were divided into control and experimental (15, 30, and 45 ppm of C. spinosa leaf extract) groups. Motility, viability, lipid peroxidation, and DNA fragmentation were evaluated 24 h after incubation. RESULTS The antioxidant effect of leaf extract was six times greater than fruit. Progressive and total motility of caper-treated groups (30 and 45 ppm) were crucially higher than the control group. Viability in all treatments was significantly higher than the control group. There was no significant difference in lipid peroxidation. DNA fragmentation in the caper-treated group (45 ppm) was significantly lower than the control group. CONCLUSIONS Our results suggest the potential positive in vitro effect of C. spinosa leaf extract on human sperm function. The use of C. spinosa leaf extract or its active metabolites in the sperm culture medium may be beneficial for maintaining motility, vitality, and sperm DNA. Since these effects were observed at very low concentrations of caper, other non-antioxidant mechanisms must be considered.

Abstract
Semen cryopreservation is routine in cattle, but the results of artificial insemination need improvement. A strategy to these aims is the supplementation of the freezing extender with novel antioxidants. This study aimed at testing the natural antioxidants curcumin and crocin as supplements to the commercial extender BIOXcell for freezing semen from 8 Holstein bulls. We tested curcumin at 0.05 and 0.1 mM (CU0.05, CU0.1) and crocin at 0.5 and 1.5 mM (CR0.5, CR1.5), with 0.5 mM reduced glutathione (GSH0.5) as reference, and a control (CTL, without supplementation). The samples were evaluated post-thawing and after 5 h at 38 °C by CASA for motility and flow cytometry for viability, apoptotic, capacitation, acrosomal status, cytoplasmic and mitochondrial reactive oxygen species (ROS) production, and chromatin status (SCSA). Control and GSH0.5 showed similar results, possibly because of the good protection from BIOXcell. CU0.05 and CU0.1 showed little effects but increased cytoplasmic ROS production and motility ALH. CR0.5 and CR1.5 decreased viability and increased apoptotic features significantly post-thawing and after the incubation, resulting in lower motility (significant after the incubation) but decreasing SCSA %HDS (loose chromatin). Whereas crocin at these concentrations seems incompatible with BIOXcell, maybe because of a prooxidant activity, curcumin use merits further research, considering the elevation of ROS with no significant negative effects.

Abstract
Previous research has proven that coxsackievirus B3 (CVB3) is broadly considered virus used in the experimental model of animals, which causes myocarditis in humans. To investigate whether there exists a cardio-protective effect of crocetin in an experimental murine model of acute viral myocarditis (AVM). Male BALB/c mice were randomly assigned to three groups: control, myocarditis treated with placebo and myocarditis treated with crocetin (n = 40 animals per group). Myocarditis was established by intraperitoneal injection with CVB3. Twenty-four hours after infection, crocetin was intraperitoneally administered for 14 consecutive days. Twenty mice were randomly selected from each group to monitor a 14-day survival rate. On day 7 and day 14, eight surviving mice from each group were sacrificed and their hearts and blood were obtained to perform serological and histological examinations. Expression of ROCKs, interleukin-17 (IL-17), interleukin-1β (IL-1β), tumor necrosis factor-α (TNFα), RORγt, and Foxp3 was quantified by RT-PCR. Plasma levels of TNFα, IL-1β and IL-17 were measured by ELISA. In addition, protein levels of IL-17 and ROCK2 in cardiac tissues were analyzed by Western blot. Crocetin treatment significantly increased survival, attenuated myocardial necrotic lesions, reduced CVB3 replication and expression of ROCK2 and IL-17 in the infected hearts. ROCK pathway inhibition was cardio-protective in viral myocarditis with increased survival, decreased viral replication, and inflammatory response. These findings suggest that crocetin is a potential therapeutic agent for patients with viral myocarditis.

Abstract
Saffron (Crocus sativus L.) is used as a spice for its organoleptic characteristics related to its coloring and flavoring properties, and it has been also used in traditional medicine to treat various diseases. The main chemical components responsible for these properties are crocin, crocetin and safranal. These compounds have been shown to have a wide spectrum of biological activities, including several properties as antigenotoxic, antioxidant, anticancer, anti-inflammatory, antiatherosclerotic, antidiabetic, hypotensive, hypoglycemic, antihyperlipidemic, antidegenerative and antidepressant, among others. This review article highlights the antioxidant effects of these bioactive compounds to reduce reactive oxygen species (ROS) and the mechanisms of action involved, since there are a multitude of diseases related to oxidative stress and the generation of free radicals (FRs). Recent studies have shown that the effects of crocin, crocetin and safranal against oxidative stress include the reduction in lipid peroxidation (malondialdehyde [MDA] levels) and nitric oxide (NO) levels, and the increase in the levels of glutathione, antioxidant enzymes (superoxide dismutase [SOD], catalase (CAT) and glutathione peroxidase [GPx]) and thiol content. Therefore, due to the great antioxidant effects of these saffron compounds, it makes saffron a potential source of bioactive extracts for the development of bioactive ingredients, which can be used to produce functional foods.

Abstract
Crocetin is an active constituent of saffron recently used as antioxidant for embryo culture. The aim of this study was to test the effect of crocetin added in the in vitro maturation (IVM) of prepubertal goat oocytes on the embryo development after in vitro fertilization (IVF), intracytoplasmic sperm injection (ICSI) and parthenogenetic activation (PA). Cumulus-oocyte complexes (COCs) were released from slaughterhouse ovaries of prepubertal goats and in vitro matured in supplemented TCM 199 medium during 24 h without (control group) and with crocetin. In Experiment 1, we evaluated the effect of the IVM supplementation with 0 μM (control), 0.5 μM, 1 μM and 2 μM of crocetin on the blastocyst development after IVF. No significant differences were obtained on blastocyst formation among groups (12, 7, 10, 11%; respectively). Although the blastocyst total cell number was higher in 1 μM crocetin group (150.7 cells) compared to the control (105.5), 0.5 μM (116.2) and 2 μM (93.7) crocetin groups, no significant differences were detected. In experiment 2, we assessed the effect of 1 μM crocetin supplementation in the IVM medium on the oocyte GSH level, ROS level and mitochondrial activity. ROS was significantly higher in the control than in the crocetin group (P < 0.05), but no differences in GSH level and mitochondrial activity were observed. In experiment 3, we evaluated the effect of 1 μM crocetin on the blastocyst development of oocytes after ICSI and PA. No statistical differences were found on blastocyst rate or cell number. However, compared with control, crocetin groups led to higher cleavage (59 vs. 67%, respectively, P = 0.09) and blastocyst rates (19 vs. 12%, respectively; P = 0.12) after ICSI. Although crocetin reduced ROS levels in prepubertal goat oocytes, it did not have a significant effect on oocyte embryo developmental competence.

Abstract
The aim of the study was to determine whether the presence of astaxanthin (ASX) protects boar spermatozoa against damage related to cryopreservation. Pooled ejaculates extended in Beltsville Thawing Solution (BTS) were used. Three experiments were conducted: 1) sperm samples were pre-incubated overnight (17 °C) with ASX (0, 0.5, 5, 15 μM) prior to freezing and then frozen using cooling and thawing extenders supplemented with ASX (0, 0.5, 5, 15 μM); 2) sperm samples were treated with ASX (0, 0.5, 5, 15 μM) only during overnight pre-incubation (17 °C) prior to cryopreservation; and 3) a thawing extender was supplemented with ASX (0, 0.5, 5, 15 μM). The groups were as follows: control (C; no treatment), ASX 1 (0.5 μM), ASX 2 (5 μM) and ASX 3 (15 μM). Total (TM) and progressive (PM) motility was analyzed using CASA, while sperm viability, reactive oxygen species generation, lipid peroxidation and apoptoticlike changes were analyzed using flow cytometry. Sperm variables were evaluated prior to freezing as well as 30 and 150 min after thawing. In Experiment 1, the values of TM and sperm viability post-thaw were less in the ASX 3 than C group. In Experiment 2, there was no effect of ASX on any of the sperm variables evaluated, while in Experiment 3, apoptotic-like changes were less in the ASX 1 than C group. In conclusion, there was a subtle beneficial effect on cryopreserved boar spermatozoa after addition of ASX to thawing media.

Abstract
Development of in vitro reproduction techniques has not only offered some infertile couples the possibility to have a child, it also revolutionized animal reproduction. Although in vitro reproduction techniques for humans or domestic and non-domestic animals have been designed to mimic in vivo conditions, modifications due to environmental effects or in vitro manipulation of gametes and embryos are unavoidable. For male gametes, in vitro manipulations include techniques to select spermatozoa, cryopreservation and other incubation procedures, during which spermatozoa may be exposed to oxidative stress and other insults that may damage their functions and DNA. The aim of this review is to provide an overview of key studies reporting sperm damage during in vitro manipulation, with particular focus on effects on DNA integrity, a fundamental factor for fertilization and transmission of paternal genetic information to offspring.

Abstract
We performed the exposure of bovine oocytes to anethole during in vitro maturation (0 or 300 µg/ml), during in vitro embryo production (0, 30, 300 or 2000 µg/ml), or during both periods to determine the rates of 2-4 cells embryos, blastocysts rates and cells numbers, as well as the production of reactive oxygen species (ROS). Bovine ovaries (n = 240) were collected from a local abattoir after slaughter and cumulus-oocyte complexes (COCs) with homogeneous and non-dark cytoplasm, surrounded by two or more compact layers of cumulus cells, and an intact zona pellucida were selected for in vitro maturatuion (IVM). Mature oocytes were then submitted to in vitro fertilization (IVF) and in vitro embryo production (IVP) in culture medium supplemented or not with different concentrations of anethole, as described above. Although IVM medium supplementation with 300 µg/ml anethole improved the rates of bovine blastocysts formation, we demonstrated that IVP medium supplementation with 30 µg/ml anethole, regardless of IVM medium enrichment, considerably enhanced blastocysts rates. Furthermore, ROS levels were decreased only when anethole was added to the IVP medium without previous IVM medium supplementation.

Abstract
Natural products with high pharmacological potential and low toxicity have been considered as the novel therapeutic agents. Crocetin is an active constituent of saffron (Crocus sativus L.) stigma, which in its free-acid form is insoluble in water and most organic solvents. Crocetin exhibits various health-promoting properties including anti-tumor, neuroprotective effects, anti-diabetics, anti-inflammatory, anti-hyperlipidemia, etc. These therapeutic effects can be achieved with different mechanisms such as improvement of oxygenation in hypoxic tissues, antioxidant effects, inhibition of pro-inflammatory mediators, anti-proliferative activity and stimulation of apoptosis in cancer cells. It is also worth considering that crocetin could be tolerated without major toxicity at therapeutic dosage in experimental models. In the present review, we discuss the biosynthesis, pharmacokinetic properties of crocetin and provide a comprehensive study on the biological activities and toxicity along with the mechanism of actions and clinical trials data of crocetin.

Abstract
Cancer therapies are associated with increased infertility risk due to accelerated reproductive aging. Oxidative stress (OS) is a potential mechanism behind ovarian toxicity by cyclophosphamide (CPM), the most ovotoxic anticancer drug. An important sensor of OS is SIRT1, a NAD+-dependent deacetylase which regulates cellular defence and cell fate. This study investigated whether the natural carotenoid crocetin and the synthetic compound AS101 protect the ovary against CPM by modulating SIRT1 and mitochondrial markers. We found that the number of primordial follicles of female CD1 mice receiving crocetin plus CPM increased when compared with CPM alone and similar to AS101, whose protective effects are known. SIRT1 increased in CPM mouse ovaries revealing the occurrence of OS. Similarly, mitochondrial SIRT3 rose, whilst SOD2 and the mitochondrial biogenesis activator PGC1-α decreased, suggesting the occurrence of mitochondrial damage. Crocetin and AS101 administration prevented SIRT1 burst suggesting that preservation of redox balance can help the ovary to counteract ovarian damage by CPM. Decreased SIRT3 and increased SOD2 and PGC1-α in mice receiving crocetin or AS101 prior to CPM provide evidence for mitochondrial protection. Present results improve the knowledge of ovarian damage by CPM and may help to develop interventions for preserving fertility in cancer patients.
