Abstract
Protein diets are required for the normal development of the reproductive system and their inadequacy or deficiency might have hazardous functional complications during maturational and developmental stages. The study was carried out to evaluate the effect of selenium (Se) and zinc (Zn) supplementation on the male and female reproductive organs of rats with postnatal protein malnutrition. Male and female weanling rats were randomly assigned to six groups respectively. The adequate protein diet rats were fed with 16% casein diet while the protein malnourished diet (PMD) rats were fed with 5% casein diet. After the 8th week of feeding, Se (sodium selenite; Na2SeO3) and Zn (zinc sulfate; ZnSO4·7H2O) were supplemented for 3 weeks. The growth curve of body weights, lipid profile, testosterone and progesterone level, Na+-K+-ATPase activity, oxidative stress, and antioxidant status were evaluated. The results showed that PMD reduced the body weights of male and female rats. It also reduced the activities of catalase and glutathione peroxidase in the testes, but reductions in superoxide dismutase and glutathione-S-transferase activities, glutathione, vitamins C and E, testosterone, and progesterone levels were observed in both the testes and ovaries. Furthermore, PMD increased the nitric oxide level in both organs and altered the plasma lipid profiles in both sexes. Se and Zn supplementation, however, restored almost all the alterations observed in all the parameters analyzed. In conclusion, Se and Zn supplementation protects the male and female reproductive organs of rats against postnatal protein malnutrition.

Abstract
Selenium (Se), an essential trace element, plays an important role in the antioxidative defense mechanism, and it has been proven to improve fertility and reproductive efficiency in dairy cattle. The present study evaluated the potential protective action of Se supplement of in vitro maturation (IVM) media on the maturation and subsequent development of bovine cumulus-oocyte complexes (COCs) exposed to heat stress (HS). The treatment with Se improved the viability of cumulus cells (CCs) and oocytes (P < 0.05). The proportion of oocytes reached metaphase II (MII) and those arrested at metaphase I (MI) was greater and lower in treatment than control respectively (P < 0.05). Supplementation with Se increased the percentage of cleaved embryos, total blastocysts, and blastocyst/cleavage ratio (P < 0.05). Moreover, the upregulation of CCND1, SEPP1, GPX-4, SOD, CAT, and downregulation of GRP78, CHOP, and BAX in both Se-treated CCs and oocytes were recorded. The upregulation of NRF2 was detected in Se-treated CCs other than in oocytes, which showed upregulation of IGF2R and SOX-2 as the markers of quality as well. Se supplement in IVM media improved the viability, maturation, and the level of transcripts related to antioxidant defense and quality of heat-treated oocytes, which coincided with greater subsequent development outcomes. Se ameliorated the viability of CCs along with upregulation of antioxidative candidate gene expression and downregulation of apoptosis-related ones to support their protective role on restoring the quality of oocytes against compromising effects of HS.

Abstract
Cancer is the leading cause of death worldwide. Fortunately, the survival rate of cancer continues to rise, owing to advances in cancer treatments. However, these treatments are gonadotoxic and cause infertility. Ovarian tissue cryopreservation and transplantation (OTCT) is the most flexible option to preserve fertility in women and children with cancer. However, OTCT is associated with significant follicle loss and an accompanying short lifespan of the grafts. There has been a decade of research in cryopreservation-induced oxidative stress in single cells with significant successes in mitigating this major source of loss of viability. However, despite its success elsewhere and beyond a few promising experiments, little attention has been paid to this key aspect of OTCT-induced damage. As more and more clinical practices adopt OTCT for fertility preservation, it is a critical time to review oxidative stress as a cause of damage and to outline potential ameliorative interventions. Here we give an overview of the application of OTCT for female fertility preservation and existing challenges; clarify the potential contribution of oxidative stress in ovarian follicle loss; and highlight potential ability of antioxidant treatments to mitigate the OTCT-induced injuries that might be of interest to cryobiologists and reproductive clinicians.

Abstract
Background Prolactin (PRL) has been reported to be associated with oxidative stress, which is an important contributor leading to cell apoptosis. However, little is known about the mechanisms underlying the effects of PRL on cytotoxicity and oxidative stress in ovine ovarian granulosa cells (GCs). Methods Ovine ovarian GCs were treated with 0, 4, 20, 100 and 500 ng/mL of PRL. Then, the cytotoxicity, cell viability, malondialdehyde (MDA), reactive oxygen species (ROS), superoxide dismutase (SOD) and total antioxidant capacity (T-AOC) of GCs were detected. Additionally, 500 ng/mL PRL was chosen as the high PRL concentration (HPC) due to its high cytotoxicity and oxidative stress. Proteomic and metabonomic were performed to examine the overall difference in proteins and metabolic pathways between C (control: 0 ng/mL PRL) and P groups (500 ng/mL PRL). Results The results indicated that GCs treated with 4 ng/mL PRL significantly decreased (P < 0.05) the cytotoxicity, ROS and MDA, increased (P < 0.05) the cell viability, SOD and T-AOC, and the GCs treated with 500 ng/mL PRL showed the opposite trend (P < 0.05). Supplementation with 500 ng/mL PRL significantly increased the proteins of MT-ND1, MAPK12, UBA52 and BCL2L1, which were enriched in ROS and mitophagy pathways. Pathway enrichment analysis showed that the pentose phosphate pathway was significantly enriched in the P group. Conclusion A low concentration of PRL inhibited cytotoxicity and oxidative stress. HPC induced oxidative stress in ovine ovarian GCs via the pentose phosphate pathway by modulating the associated proteins MT-ND1 in ROS pathway and UBA52, MAPK12 and BCL2L1 in mitophagy pathway, resulting in cytotoxicity.

Abstract
The in vitro culture systems of ovarian preantral follicles have been developed for studying follicular and oocyte growth, for future use of immature oocytes as sources of fertilizable oocytes and for screening ovarian toxic substances. One of the key limitations of the in vitro culture of preantral follicles is the oxidative stress by accumulation of reactive oxygen species (ROS), which can impair follicular development and oocyte quality. Several factors are associated with oxidative stress in vitro, which implies the need for a rigorous control of the conditions as well as addition of antioxidant agents to the culture medium. Antioxidant supplementation can minimize or eliminate the damage caused by ROS, supporting follicular survival and development and producing mature oocytes competent for fertilization. This review focuses on the use of antioxidants and their role in preventing follicular damage caused by oxidative stress in the in vitro culture of preantral follicles.

Abstract
Due to the impact of the modern lifestyle, female infertility has been reduced because of different reasons. For example, in combined chemotherapeutic therapies, a small fraction of cancer survivors has faced different post-complications and side effects such as infertility. Besides, in modern society, delayed age of childbearing has also affected fertility. Nowadays, ovarian tissue cryopreservation and transplantation (OTC/T) is considered one of the appropriate strategies for the restoration of ovarian tissue and bioactivity in patients with the loss of reproductive function. In this regard, several procedures have been considered to improve the efficacy and safety of OTT. Among them, a surgical approach is used to transplant ovaries into the optimal sites, but the existence of ischemic changes and lack of appropriate revascularization can lead to bulk follicular atresia. Besides, the role of OTC/T is limited in women of advanced maternal age undergoing lifesaving chemo-radiation. As a correlate, the development of de novo approaches with efficacious regenerative outcomes is highly welcomed. Tissue engineering shows high therapeutic potentialities to restore fertility in males and females using the combination of biomaterials, cells, and growth factors. Unfortunately, most synthetic and natural materials are at the experimental stage and only the efficacy has been properly evaluated in limited cases. Along with these descriptions, strategies associated with the induction of angiogenesis in transplanted ovaries can diminish the injuries associated with ischemic changes. In this review, the authors tried to summarize recent techniques, especially tissue engineering approaches for improving ovarian function and fertility by focusing on angiogenesis and neovascularization.

Abstract
In the field of reproductive science, there is an increased interest in the application of ovarian preantral follicles. Since the ovary contains a great amount of preantral follicles (PAF), the cryopreservation and in vitro culture of such follicles support the fertility preservation of domestic animals with high genetic value, endangered or zoo animals, and women before anticancer therapy. To date, no standard freezing or vitrification protocol is available in human or animals. The aim of the present study was to examine the viability of preantral follicles cryopreserved using freezing or vitrification protocols: cryotube freezing or OPS vitrification.

Abstract
This study aims to investigate the (1) expression of melatonin receptors types 1A/B (MTNR1A/B) in bovine ovaries and (2) the in vitro effects of melatonin on secondary follicle development, antrum formation, viability, and expression of messenger ribonucleic acid (mRNA) for superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase-1 (GPX1) and peroxiredoxin 6 (PRDX6). The expression of MTNR1A/B in bovine ovarian follicles was demonstrated by immunohistochemistry. To choose the most effective concentration of melatonin on follicular growth and viability, isolated secondary follicles were cultured individually at 38.5°C, with 5% CO2 in air, for 18 d in TCM-199+ alone or supplemented with 10-11, 10-9, 10-7 or 10-5 M melatonin. Then, melatonin receptor antagonist, luzindole, was tested to further evaluate the mechanisms of actions of melatonin, that is, the follicles were cultured in control medium alone or supplemented with 10-7 M melatonin, 10 µM luzindole and both 10-7 M melatonin and 10 µM luzindole. Follicular growth, morphology and antrum formation were evaluated at days 6, 12 and 18. At the end of culture, viability of secondary follicles was analyzed by calcein-AM and ethidium homodimer-1, and the relative levels of mRNA for SOD, CAT, GPX1 and PRDX6 were evaluated by real time polymerase chain reaction. Immunohistochemistry results showed expression of MTNR1A/B in oocyte and granulosa cells of primordial, primary, secondary and antral follicles. Secondary follicles cultured in medium supplemented with melatonin at different concentrations had well preserved follicles after 18 d of culture. Furthermore, follicles cultured in presence of 10-7 M melatonin presented significantly higher diameters than those cultured in other treatments. The presence of melatonin receptor antagonist, luzindole, blocked the effects of melatonin on follicular growth and viability. In addition, follicles cultured in medium containing only melatonin had significantly higher rates of antrum formation. Follicles cultured in medium containing only melatonin had higher relative levels of mRNA for CAT, SOD and PRDX-6 than those cultured with both melatonin and luzindole. Follicles cultured with luzindole only or both melatonin and luzindole had lower relative levels of mRNA for PRDX6 and GPX1 than those cultured control medium. In conclusion, melatonin promotes growth of bovine secondary follicles through its membrane-coupled receptors, while luzindole blocks the effects of melatonin on follicle growth and reduces the expression of antioxidant enzymes in cultured follicles.

Abstract
This study aimed to investigate the effects of Aloe vera extract on follicular growth, viability, ultrastructure, and mRNA levels for superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase 1 (GPX1) and peroxiredoxin 6 (PRDX6) in bovine secondary follicles cultured in vitro. To this end, secondary follicles were mechanically isolated from the ovarian cortex and cultured at 38.5 °C, with 5% CO2 in air, for 18 days in TCM-199+ alone or supplemented with 2.5%, 5.0%, 10.0% and 20.0% Aloe vera extract. Follicular growth, morphology and antrum formation were evaluated every 6 days, while ultrastructure was evaluated at the end of culture. Analysis of viability was performed by calcein-AM and ethidium homodimer-1, while mRNA levels for SOD, CAT, GPX1 and PRDX6 were evaluated by real-time PCR at the end of culture. The results show that follicles cultured with 2.5% Aloe vera had increased the rate of antrum formation, while 2.5% and 5.0% Aloe vera improved follicular viability rate. Follicles cultured with 2.5% and 10.0% Aloe vera increased the levels of mRNA for SOD and GPX1 respectively, but the levels of CAT were reduced in follicles cultured with 2.5%, 5.0%, 10.0% and 20.0%. Additionally, follicles cultured with 2.5% of Aloe vera had their ultrastructure well preserved, while those cultured with 5.0%, 10.0% and 20.0% exhibited increased oocyte vacuolization and damaged organelles. In conclusion, 2.5% Aloe vera increases antrum formation, viability and expression of mRNA for SOD in cultured secondary follicles, but higher concentrations of Aloe vera have negative effects on follicular ultrastructure.

Abstract
The most common limitation of anticancer chemotherapy is the injury to normal cells. Cyclophosphamide, which is one of the most widely used alkylating agents, can cause premature ovarian insufficiency and infertility since the ovarian follicles are extremely sensitive to their effects. Although little information is available about the pathogenic mechanism of cyclophosphamide-induced ovarian damage, its toxicity is attributed to oxidative stress, inflammation, and apoptosis. The use of compounds with antioxidant and cytoprotective properties to protect ovarian function from deleterious effects during chemotherapy would be a significant advantage. Thus, this article reviews the mechanism by which cyclophosphamide exerts its toxic effects on the different cellular components of the ovary, and describes 24 cytoprotective compounds used to ameliorate cyclophosphamide-induced ovarian injury and their possible mechanisms of action. Understanding these mechanisms is essential for the development of efficient and targeted pharmacological complementary therapies that could protect and prolong female fertility.

Impaired follicular development associated with autoimmune ovarian disease (AOD), is a typical side effect of ZP3 vaccine-induced subfertility and contributes to the fertility decline, but the mechanism is unknown. In this study, a AOD model was established with recombinant mouse zona pellucida 3 (mZP3) protein in the BALB/c mice, and co-administrated with 0.5 mg/kg antioxidant stress drug sodium selenite (SS), whereas intraperitoneal injection was used and the relationships among oxidant stress (OS), follicle loss and fertility were evaluated. Here we demonstrated that ZP3 vaccination elicited high antibody titers and correlated with reductions of ovarian follicle numbers in both fertile and infertile mice, whereby magnitudes of both factors were negatively correlated with litter size. Moreover, increased OS in ovaries of mZP3-immunized mice was related to high levels of reactive oxygen species (ROS) and malondialdehyde (MDA), and is accompanied by a decrease in the total antioxidant capacity (TAC) of ovaries. Meanwhile, activation of caspase-3 and caspase-9 along with increased Bax and decreased Bcl-2 levels were observed, indicating the ongoing apoptosis of ovarian cells. Notably, inhibition of OS with SS reduced ovarian ROS and apoptosis levels, which was consisted with restoration of follicle numbers. More importantly, SS treatment when co-administered concurrently with mZP3 immunization led to significantly improved fertility (P < 0.05) and the average litter size of the mZP3-vaccinated SS-treated group increased by ~29.2% as compared with that of the vaccinated but untreated group. In conclusion, infertility caused by ZP3 vaccination was mechanistically associated with ovarian OS which triggered depletion of ovarian follicles.

Abstract
Ovarian tissue cryopreservation is the only option for preserving fertility in adult and prepubertal cancer patients who require immediate chemotherapy or do not want ovarian stimulation. However, whether ovarian tissue cryopreservation can ameliorate follicular damage and inhibit the production of reactive oxygen species in cryopreserved ovarian tissue remains unclear. Oxidative stress is caused by several factors, such as UV exposure, obesity, age, oxygen, and cryopreservation, which affect many of the physiological processes involved in reproduction, from maturation to fertilization, embryonic development, and pregnancy. Here, freezing and thawing solutions were pre-treated with N-acetylcysteine (NAC) and klotho protein upon the freezing of ovarian tissue. While both NAC and klotho protein suppressed DNA fragmentation by scavenging reactive oxygen species, NAC induced apoptosis and tissue damage in mouse ovarian tissue. Klotho protein inhibited NAC-induced apoptosis and restored cellular tissue damage, suggesting that klotho protein may be an effective antioxidant for the cryopreservation of ovarian tissue.

Abstract
PURPOSE In the present study, the authors investigated the effects of selenium on inflammation, hyaluronan production, and oxidative stress in primary cultured orbital fibroblasts of patients with Graves ophthalmopathy (GO). METHODS Orbital adipose/connective tissue specimens were obtained during the course of orbital surgery for patients with GO (n = 7) and other noninflammatory problems (n = 5). After incubation with various concentrations of sodium selenite for 48 hours, supernatants from primary cultures were collected. Hyaluronan and cytokine levels were measured using commercially available enzyme-linked immunosorbent assay kits. To determine the effect of selenium on reactive oxygen species (ROS) production stimulated by H2O2 (100 μM) for 30 minutes, the cells were pretreated with various concentrations of sodium selenite for 60 minutes. RESULTS Interleukin (IL)-6 and tumor necrosis factor-alpha levels were significantly higher in orbital fibroblasts of patients with GO than in orbital fibroblasts of control patients. Hyaluronan production was suppressed by selenium in cultured orbital fibroblasts of patients with GO. Inflammatory cytokines such as IL-1α, IL-8, and tumor necrosis factor-alpha were suppressed by selenium in cultured orbital fibroblasts of patients with GO. IL-1β and IL-6 were not suppressed by selenium in cultured orbital fibroblasts of patients with GO. Selenium pretreatment reduced intracellular ROS generation stimulated by H2O2 in cultured orbital fibroblasts of patients with GO. CONCLUSIONS In conclusion, hyaluronan production, inflammatory cytokines, and intracellular ROS generation were suppressed by selenium in cultured orbital fibroblasts of patients with GO. Several inflammatory cytokines may be suppressed by selenium in cultured orbital fibroblasts of patients with GO. This study provide the basis for use of selenium in the treatment of GO.

Abstract
BACKGROUND The aim of the present study was to investigate the effect of Sodium Selenite (SS) supplemented media on oocyte maturation, expression of mitochondrial transcription factor A (TFAM) and embryo quality. METHODS Mouse Germinal Vesicle (GV) oocytes were collected after administration of Pregnant Mare Serum Gonadotropin (PMSG); in experimental group 1, oocytes were cultured and then subjected for in vitro maturation in the absence of SS, and in experimental group 2, they were matured in vitro in the presence of 10 ng/ml of SS up to 16 hr. The control group included MII oocytes obtained from the fallopian tubes after ovarian stimulation with PMSG, followed by human chorionic gonadotropin. Then, the expression of TFAM in MII oocytes in all three groups was investigated using real-time RT-PCR. The fertilization and embryo developmental rates were assessed, and finally the quality of the blastocysts was evaluated using propidium iodide staining. RESULTS The oocyte maturation rate to MII stage in SS treated group was significantly higher than non-treated oocytes (75.65 vs. 68.17%, p<0.05). Also, the rates of fertilization, embryo development to blastocyst stage as well as the cell number of blastocyst in SS supplemented group were higher than other experimental group (p<0.05). There was a significant decrease in TFAM gene expression in both in vitro groups compared to the group with in vivo obtained oocytes (p<0.05). Moreover, there was a significant increase in TFAM gene expression in oocytes that matured in the presence of SS compared to that of the group without SS (p<0.05). CONCLUSION Supplementation of oocyte maturation culture media with SS improved the development rate of oocytes and embryo and also enhanced TFAM expression in MII oocytes which can affect the mitochondrial biogenesis of oocytes.

Abstract
This study examined the effects of zinc chloride (ZnCl2) and sodium selenite (Na2SeO3) supplementation in maturation medium on in vitro maturation (IVM) rate, oxidative biomarkers and gene expression in buffalo oocytes. Ovaries from a slaughterhouse were aspirated and good quality cumulus-oocyte complexes (COCs) with at least four layers of compact cumulus cells and evenly granulated dark ooplasm were selected. COCs were randomly allocated during IVM (22 h) to one of four treatment groups: (1) control maturation medium (basic medium), or basic medium supplemented with (2) ZnCl2 (1.5 µg/ml), (3) Na2SeO3 (5 µg/l), or (4) ZnCl2 + Na2SeO3 (1.5 µg/ml + 5 µg/l, respectively). Oocytes were denuded after 22 h of IVM in the first four replicates. Specimens were fixed and stained to evaluate the stage of nuclear maturation. The spent medium was collected for biochemical assays of total antioxidant capacity (TAC), malondialdehyde (MDA) and hydrogen peroxide concentrations. A second four replicates were used for COCs for RNA extraction. The expression levels of antioxidant (SOD1, GPX4, CAT and PRDX1), antiapoptotic (BCL2 and BCL-XL) and proapoptotic (BAX and BID) genes were measured. Supplementation with ZnCl2 and Na2SeO3 during IVM increased the ratio of oocytes reaching metaphase II at 22 h, increased TAC and decreased MDA and H2O2 concentrations in the maturation medium (P < 0.05). Moreover, beneficial effects were associated with complementary changes in expression patterns of antioxidative, antiapoptotic and proapoptotic genes, suggesting lower oxidative stress and apoptosis. Supplementation medium with zinc chloride and sodium selenite improves the maturation rate, reduces oxidative stress and increases expression levels of antioxidative and antiapoptotic genes.

Abstract
This study aimed to investigate the effects of eugenol on growth, viability, antrum formation and mRNA expression of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase 1 (GPX1) and peroxiredoxin 6 (PRDX6) in bovine secondary follicles cultured in vitro. To this end, bovine ovaries were collected from a local slaughterhouse and in the laboratory the follicles were isolated from the ovarian cortex. The follicles were then cultured in TCM-199+ alone or supplemented with different concentrations of eugenol (0.5, 5.0 and 50.0 μM). Follicular diameters and antrum formation were evaluated on days 0, 6, 12 and 18. Viability analysis was performed using calcein and ethidium homodimer. Real-time PCR was used to quantify mRNA levels for SOD, CAT, GPX1 and PRDX6 in cultured follicles. Follicular diameters and mRNA levels in follicles cultured in vitro were compared using analysis of variance and Kruskal-Wallis tests, while follicular survival and antrum formation were compared using the chi-squared test (P < 0.05). The results showed that secondary follicles cultured with eugenol maintained similar morphology and viability to follicles cultured in the control group. A progressive increase in follicular diameter was observed between days 0 and 12 for all treatments, except for follicles cultured with 50 µM eugenol. Eugenol (5.0 and 50.0 μM) increased mRNA levels for GPX1 in cultured follicles, but 0.5 μM eugenol reduced mRNA levels for SOD. The addition of eugenol did not influence mRNA expression for CAT and PRDX6. In conclusion, eugenol supplementation reduces mRNA levels for SOD and increases mRNA levels of GPX1 in bovine secondary follicles cultured in vitro.

Abstract
In vitro maturation (IVM) of oocytes is widely used in assisted reproduction technologies. The present study aimed to improve the in vitro oocyte maturation and its development through enriching the culture media with sodium selenite (SS). Moreover, the effects of SS on the expression of the oocytes apoptosis-related genes were assessed. In this study, male and female NMRI mice were used and after collecting their germinal vesicle (GV) oocytes, they were cultured with SS (experimental group) and without SS (control group). Collected metaphase II oocytes (MII) from the fallopian tube were considered as in vivo group. After in vitro culture, the oocytes were assessed in terms of nuclear maturation. The MII oocytes were inseminated and the development was examined until the blastocyst stage. Also, oocytes were subjected to the molecular analysis for evaluating the expression of BAX, BCL2, P53, and BAD genes using the real-time RT-PCR. The maturation rate was significantly increased in the SS supplemented group compared to the control one. The developmental rate of the embryos was significantly higher for both of the in vivo and SS supplemented groups rather than the control one, however, no significant difference was seen between these rates of the experimental and in vivo groups. Real-time RT-PCR did not show any significant differences in the expression of the apoptosis-related genes for all of the studied groups. The p53 gene was not expressed in any of groups. Sodium selenite improved the oocyte developmental competence but did not change the expression of the apoptosis-related genes in MII oocytes.

Abstract
Selenium (Se) is an essential trace element with important functions in animals and whose deficiency is associated with reproductive failures. The aim of this study was to investigate the effect of Se concentrations during in vitro maturation (IVM) of Bos taurus oocyte within the reference ranges for Se status in cattle. For this purpose, Aberdeen Angus cumulus-oocyte complexes (COCs) were matured in IVM medium supplemented with 0, 10, 50, and 100 ng/mL Se (control, deficient, marginal, and adequate, respectively). The results demonstrated that marginal and adequate Se concentrations added during IVM increased viability and non-apoptotic cumulus cells (CC). Moreover, the addition of Se to culture media decreased malondialdehyde level in COC with all studied concentrations and increased total glutathione content in CC and oocytes with 10 ng/mL Se. On the other hand, total antioxidant capacity of COC, nuclear maturation, and the developmental capacity of oocytes were not modified by Se supplementation. However, 10 ng/mL Se increased hatching rate. In conclusion, supplementation with 10 ng/mL Se during in vitro maturation of Bos primigenius taurus oocytes should be considered to improve embryo quality.

Abstract
Objective Vitrification of the ovarian tissue is one of the techniques recommended for preserving the fertility of women
who are dealing with infertility. Despite its benefits, our information about the molecular aspects of ovarian follicles
vitrification is somehow ambiguous. Therefore, the aim of this study was to evaluate the expression pattern of DNA
repair genes in vitrified preantral follicles.
Materials and Methods In this experimental study, the isolated preantral follicles (n=906) from 14-16 days old mice
(n=12) were divided into three groups: fresh, toxic and vitrified which were cultured in vitro for 12 days. Preantral
follicles were vitrified using cryotop followed by exposure to equilibration solution for five minutes and vitrification
solution (VS) for 30 seconds. In the toxic group, preantral follicles were only placed in equilibration and vitrification
media and they were then placed in the warming solutions without exposure to liquid nitrogen. On the second and
sixth days of the culture period, real-time quantitative reverse transcription-polymerase chain reaction (qRT-PCR) was
carried out to evaluate expression of the selected genes involved in DNA repair, including Msh6 (MutS homolog 6),
Mre11 (Meiotic recombination 11), Brca1 (Breast cancer type 1), Rad51 (RAD51 recombinase), Pcna (Proliferating
cell nuclear antigen) and Atm (ATM serine/threonine kinase). In addition, developmental parameters including growth,
survival rate, antrum cavity formation and ovulation were analyzed.
Results The relative mRNA expression of Msh6, Mre11, Brca1, Rad51, Pcna and Atm on the second and sixth days
of the culture period in vitrified group was significantly higher than those of the control and toxic groups, but there was
no significant difference between the toxic and control groups. In addition, developmental parameters of follicles were
similar in both toxic and control groups, while both were significantly higher than that of vitrified group.
Conclusion Vitrification changes the expression pattern of DNA repair genes of the mouse preantral follicles.

Abstract
Objective Many attempts have been made to preserve fertility by improving the cryopreservation of the ovarian tissue.
This current studyaimed to improve of direct cover vitrification (DCV) protocol on follicular preservation and angiogenesis in
autografted ovarian tissue.
Materials and Methods In this experimental study, sixty five female Balb/c mice (5-6 week-old) were anesthetized and
their ovaries were dissected. The left ovaries were vitrified by DCV solution, thawed by descending concentrations of
sucrose, and then autografted subcutaneously. The right ovaries were autografted with no vitrification procedure prior
to transplantation. The animals were sacrificed under anesthesia on the 7thday after transplantation to obtain ovarian
tissue. Follicular quality was assessed by histological and ultrastructure observations, and angiogenesis was examined
by immunohistochemical staining and real-time polymerase chain reaction (PCR) analysis.
Results The histological and ultrastructure features of the follicles preserved well after vitrification of the ovarian tissue
by 10% ethylene glycol (EG) and 10% dimethyl sulfoxide (DMSO). Revascularizationwas manifested prominently in the
DCV1-vitrified/grafted ovaries by von Willebrand factor (vWF) and alpha smooth muscle actin (α-SMA) immunostaining.
The ovarian tissue vitrified in DCV1 protocol had higher expression levels of angiopoietin-2 (Ang-2) and vascular
endothelial growth factor (VEGF) 7 days after autotransplantation (P<0.01).
Conclusion These findings suggest that DCV with 10% of both EG and DMSO, is an effective cryopreservation
solution for preservation of good quality follicles as well an upregulation of angiogenic factors after ovarian tissue
transplantation.

Abstract
Oxidative stress significantly contributes to heart disease, and thus might be a promising target for ameliorating heart failure. Mounting evidence suggests that selenium has chemotherapeutic potential for treating heart disease due to its regulation of selenoproteins, which play antioxidant regulatory roles. Oxidative stress-induced cardiomyocyte cell cycle arrest contributes to the loss of cardiomyocytes during heart failure. The protective effects and mechanism of selenium against oxidative stress-induced cell cycle arrest in cardiomyocytes warrant further study. H9c2 rat cardiomyoblast cells were treated with hydrogen peroxide in the presence or absence of selenium supplementation. Na2SeO3 pretreatment alleviated H2O2-induced oxidative stress, increased thioredoxin reductase (TXNRD) activity and glutathione peroxidase (GPx) activity and counteracted the H2O2-induced cell cycle arrest at the S phase. These effects were accompanied by attenuation of the H2O2-induced strengthening of the G2/M-phase inhibitory system, including increased mRNA and protein levels of cyclin-dependent kinase 1 (CDK1) and decreased p21 mRNA levels. Notably, Na2SeO3 pretreatment activated the PI3K/AKT signaling pathway, and inhibition of PI3K counteracted the protective effects of selenium on H2O2-induced cell cycle arrest. We corroborated our findings in vivo by inducing oxidative stress in pig heart by feeding a selenium deficient diet, which decreased the TXNRD activity, inactivated PI3K/AKT signaling and strengthened the G2/M-phase inhibitory system. We concluded that the cardioprotective effects of selenium supplementation against oxidative stress-induced cell cycle arrest in cardiomyocytes might be mediated by the selenoprotein-associated (GPx and TXNRD) antioxidant capacity, thereby activating redox status-associated PI3K/AKT pathways, which promote cell cycle progression by targeting the G2/M phase inhibitory system. This study provides new insight into the underlying mechanisms of cardioprotection effects of selenium at the cellular level.

Antioxidants (Basel) 2019; 8:antiox8120634. [PMID: 31835711 PMCID: PMC6969897 DOI: 10.3390/antiox8120634] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2019] [Revised: 12/09/2019] [Accepted: 12/09/2019] [Indexed: 12/15/2022] Open
Abstract
Female reproductive (ovarian) aging is distinctively characterized by a markedly reduced reproductive function due to a remarkable decline in quality and quantity of follicles and oocytes. Selenium (Se) has been implicated in playing many important biological roles in male fertility and reproduction; however, its potential roles in female reproduction, particularly in aging subjects, remain poorly elucidated. Therefore, in the current study we used a murine model of female reproductive aging and elucidated how different Se-levels might affect the reproductive efficiency in aging females. Our results showed that at the end of an 8-week dietary trial, whole-blood Se concentration and blood total antioxidant capacity (TAOC) were significantly reduced in Se-deficient (0.08 mg Se/kg; Se-D) mice, whereas both of these biomarkers were significantly higher in inorganic (0.33 mg/kg; ISe-S) and organic (0.33 mg/kg; OSe-S) Se-supplemented groups. Similarly, compared to the Se-D group, Se supplementation significantly ameliorated the maintenance of follicles and reduced the rate of apoptosis in ovaries. Meanwhile, the rate of in vitro-produced embryos resulting from germinal vesicle (GV) oocytes was also significantly improved in Se-supplemented (ISe-S and OSe-S) groups compared to the Se-D mice, in which none of the embryos developed to the hatched blastocyst stage. RT-qPCR results revealed that mRNA expression of Gpx1, Gpx3, Gpx4, Selenof, p21, and Bcl-2 genes in ovaries of aging mice was differentially modulated by dietary Se levels. A considerably higher mRNA expression of Gpx1, Gpx3, Gpx4, and Selenof was observed in Se-supplemented groups compared to the Se-D group. Similarly, mRNA expression of Bcl-2 and p21 was significantly lower in Se-supplemented groups. Immunohistochemical assay also revealed a significantly higher expression of GPX4 in Se-supplemented mice. Our results reasonably indicate that Se deficiency (or marginal levels) can negatively impact the fertility and reproduction in females, particularly those of an advancing age, and that the Se supplementation (inorganic and organic) can substantiate ovarian function and overall reproductive efficiency in aging females.

Abstract
The objective of this study was to test the efficiency of powdered coconut water (ACP-406®) base-medium without or with the addition of supplements on in vitro culture of isolated goat secondary follicles. Follicles were cultured for 18 days in α-MEM or in ACP-406®, both without supplements (referred to as α-MEM and ACP, respectively), or both supplemented with BSA, insulin, transferrin, selenium, glutamine, hypoxanthine, and ascorbic acid (referred to as α-MEM+ and ACP+). Follicular morphology, antrum formation, follicular and oocyte diameter, levels of glutathione (GSH), and chromatin configuration after in vitro maturation were evaluated. At the end of culture, ACP-406® base-medium (without or with supplements) showed a higher (P < 0.05) percentage of normal follicles than α-MEM (without or with supplements). Antrum formation was similar among α-MEM+, ACP and ACP+, and significantly higher than α-MEM without supplements. The follicular diameter was greater in ACP+ than α-MEM, and similar to other treatments. Moreover, fully and daily grown rates were higher (P < 0.05) in ACP-406® base-medium (without or with supplements) than α-MEM (without or with supplements). Levels of GSH were similar between ACP+ and α-MEM+ treatments. Both ACP+ and α-MEM+ allowed meiotic resumption without a significant difference between the two groups. In conclusion, supplemented ACP-406® base-medium maintained follicular survival and promoted the development as well as meiotic resumption of isolated goat secondary follicles cultured in vitro for 18 days.

Selenium, Selenoproteins, and Female Reproduction: A Review. Molecules 2018; 23:molecules23123053. [PMID: 30469536 PMCID: PMC6321086 DOI: 10.3390/molecules23123053] [Citation(s) in RCA: 68] [Impact Index Per Article: 11.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2018] [Revised: 11/11/2018] [Accepted: 11/20/2018] [Indexed: 01/31/2023] Open
Abstract
Selenium (Se) is an essential micronutrient that has several important functions in animal and human health. The biological functions of Se are carried out by selenoproteins (encoded by twenty-five genes in human and twenty-four in mice), which are reportedly present in all three domains of life. As a component of selenoproteins, Se has structural and enzymatic functions; in the latter context it is best recognized for its catalytic and antioxidant activities. In this review, we highlight the biological functions of Se and selenoproteins followed by an elaborated review of the relationship between Se and female reproductive function. Data pertaining to Se status and female fertility and reproduction are sparse, with most such studies focusing on the role of Se in pregnancy. Only recently has some light been shed on its potential role in ovarian physiology. The exact underlying molecular and biochemical mechanisms through which Se or selenoproteins modulate female reproduction are largely unknown; their role in human pregnancy and related complications is not yet sufficiently understood. Properly powered, randomized, controlled trials (intervention vs. control) in populations of relatively low Se status will be essential to clarify their role. In the meantime, studies elucidating the potential effect of Se supplementation and selenoproteins (i.e., GPX1, SELENOP, and SELENOS) in ovarian function and overall female reproductive efficiency would be of great value.

Abstract
The aim of this study was to evaluate the effect of the conditioned medium of ovine Wharton's jelly-derived mesenchymal stem cells (oWJ-MSCs) on the morphology, growth, reactive oxygen species (ROS) and glutathione (GSH) intracellular levels, active mitochondria, and meiotic resumption of isolated ovine secondary follicles in vitro. The oWJ-MSCs were isolated and the medium where they were cultured was recovered (conditioned medium). Isolated ovine secondary follicles were cultured for 6 days in 1) supplemented α-MEM+ (control); 2) 50% α-MEM+ + 50% conditioned medium (α-MEM + CM group) or 3) conditioned medium only (CM group). The parameters analyzed were morphology, antrum formation, follicle and oocyte growth, ROS and GSH levels, mitochondrial activity and meiotic resumption. The percentage of normal follicles, antrum formation, and fully grown oocytes did not differ (P > 0.05) among treatments. Follicles cultured in α-MEM + CM group had greater (P < 0.05) diameter than other treatments after culture. Moreover, the diameter of the follicles cultured in CM alone was higher (P < 0.05) than in the α-MEM+. In addition, α-MEM + CM and CM treatments increased the growth rate compared to the α-MEM+. Treatments containing conditioned medium (α-MEM + CM or CM) significantly reduced ROS levels compared to the control medium. Moreover, mitochondrial activity was higher in α-MEM+ and α-MEM + CM than in CM alone. All treatments showed oocytes in GV, GVBD and MI. In conclusion, oWJ-MSCs conditioned medium, especially when associated with α-MEM, improves the growth of secondary follicles and reduces ROS generation after short-term culture.

Abstract
Background The aim of this study was to evaluate the effect of the co-administration of probiotic and selenium on parameters of mental health, hormonal profiles, and biomarkers of inflammation and oxidative stress in women with PCOS. Data on the effects of selenium and probiotic co-supplementation on mental health, hormonal and inflammatory parameters of patients with polycystic ovary syndrome (PCOS) are scarce. This investigation was carried out to evaluate the effects of selenium and probiotic co-supplementation on mental health, hormonal and inflammatory parameters in women with PCOS. Methods This randomized, double-blinded, placebo-controlled clinical trial was conducted on 60 subjects, aged 18–40 years old. Participants were randomly allocated into two groups to intake 8 × 109 CFU/day probiotic plus 200 μg/day selenium supplements (n = 30) or placebo (n = 30) for 12 weeks. Hormonal and inflammatory parameters were measured at baseline and after the 12-week intervention. Results Probiotic and selenium co-supplementation resulted in a significant improvement in beck depression inventory (β − 0.76; 95% CI, − 1.26, − 0.26; P = 0.003), general health questionnaire scores (β − 1.15; 95% CI, − 1.97, − 0.32; P = 0.007) and depression anxiety and stress scale scores (β − 1.49; 95% CI, − 2.59, − 0.39; P = 0.009) compared with the placebo. Furthermore, probiotic and selenium co-supplementation significantly reduced total testosterone (β − 0.26 ng/mL; 95% CI, − 0.51, − 0.02; P = 0.03), hirsutism (β − 0.43; 95% CI, − 0.74, − 0.11; P = 0.008), high-sensitivity C-reactive protein (hs-CRP) (β − 0.58 mg/L; 95% CI, − 0.97, − 0.19; P = 0.004) and malondialdehyde (MDA) levels (β − 0.29 μmol/L; 95% CI, − 0.56, − 0.02; P = 0.03), and significantly increased total antioxidant capacity (TAC) (β + 84.76 mmol/L; 95% CI, + 48.08, + 121.44; P < 0.001) and total glutathione (GSH) levels (β + 26.78 μmol/L; 95% CI, + 4.33, + 49.23; P = 0.02) compared with the placebo. Conclusions Overall, the co-administration of probiotic and selenium for 12 weeks to women with PCOS had beneficial effects on mental health parameters, serum total testosterone, hirsutism, hs-CRP, TAC, GSH and MDA levels.

Abstract
OBJECTIVE The present study analyzed the quality of bovine ovarian tissue after vitrification in a metal closed chamber, in terms of putative changes in tissue viability (lactate dehydrogenase -LDH- release), anti-oxidant defenses, and redox parameters caused by cryopreservation. METHODS Small and large fragmented bovine ovarian tissue specimens were vitrified in a metal chamber. After rewarming, tissue samples were fixed or cultured for 48 hours. Glutathione (GSH), protein sulfhydryl content, Total Radical Trapping Antioxidant Potential (TRAP), and lactate dehydrogenase were analyzed immediately after rewarming and after tissue culture. RESULTS No changes in antioxidant parameters or viability of rewarmed tissue samples were found immediately or 48h after vitrification. The method of vitrification in a metal closed chamber used in this study preserved the quality of bovine ovarian tissue. Furthermore, our data showed that the size of the tissue specimens did not affect post-vitrification biochemical viability parameters. CONCLUSIONS We believe that the vitrification methodology employed in the present study is safe and effective, and should be evaluated for use in humans.

Abstract
BACKGROUND The aim of this study was to design and assess the effects of hydroalcoholic extract of Matricaria chamomilla (MC) on preantral follicle culture of mouse ovaries in a three-dimensional culture system. METHODS Isolated preantral follicles were randomly divided into three main groups: the control group containing 10% fetal bovine serum without MC extract (G1), the first experimental group supplemented with 25 μg/ml hydroalcoholic extract of chamomile (G2), and the second experimental group supplemented with 50 μg/ml hydroalcoholic extract of chamomile (G3). RESULTS After 12 days of culture, the survival rate (P < 0.05), antrum formation (P < 0.01), metaphase two oocytes (P < 0.01), and the expression of PCNA (P < 0.05) and FSHR (P < 0.05) genes significantly decreased in G3 as compared with G1. On the other hand, at the last day of culture (day 12), the mean diameter of follicles cultured in the medium which was supplemented with 50 μg/ml hydroalcoholic extract of chamomile significantly decreased as compared with the G1 (P < 0.05). In addition, the levels of progesterone and dehydroepiandrosterone hormones significantly increased in the medium of G3 relative to G1 (P < 0.01), while in the medium of G1, the level of 17β-estradiol was significantly higher than that of other groups (P < 0.01). Reactive oxygen species levels of metaphase II oocytes were significantly decreased in G2 as compared with G1 (P < 0.01). CONCLUSION Adding chamomile extract to culture media appeared to decrease follicular function and development.

Abstract
The risk of premature ovarian failure (POF) increases in association with alteration in immunological parameters and oxidative stress (OS). Adequate intake of trace elements is required for antioxidant property and immune defense mechanism. The aim of this study was to explore the involvement of trace elements, OS, and immunological parameters in POF. This was a cross-sectional, case-control study, involving 65 participants divided into the POF (n = 35) and control (n = 30) groups. Serum levels of Se, Zn, and Cu were determined along with hormonal, OS, and immunological markers. POF group had significantly lower levels of Zn, Cu, Se, and Zn:Cu ratio. However, Se:Cu ratio was not significant between the groups. FSH and LH levels were negatively correlated with Zn and Cu levels and positively correlated with Se levels. Estrogen levels were negatively correlated with all the studied trace elements. Inter-element association between Zn and Se was significant in POF (r = - 0.39, p = 0.02) compared to control group (r = - 0.078, p = 0.65). In all the POF patients, SOD and GPx activities were significantly (p < 0.05) lower and MDA level was higher (p > 0.05) than control group. B cell marker CD19 was significantly (p < 0.0001) high in POF group. There are involvement of trace elements in hormonal regulation and antioxidant defense mechanism, which once gets altered leads to high ROS generation and affect functions of the immune system. Exaggereative immune system causing higher expression of B cell associated markers (CD19) leading to autoimmune condition in POF.

Amoushahi M, Salehnia M. Reactive oxygen species level, mitochondrial transcription factor A gene expression and succinate dehydrogenase activity in metaphase II oocytes derived from in vitro cultured vitrified mouse ovaries. VETERINARY RESEARCH FORUM : AN INTERNATIONAL QUARTERLY JOURNAL 2018; 9:145-152. [PMID: 30065803 PMCID: PMC6047572 DOI: 10.30466/vrf.2018.30824] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/10/2018] [Accepted: 12/12/2018] [Indexed: 12/13/2022]
Abstract
The aim of this study was to evaluate the effects of ovarian tissue vitrification and two-step in vitro culture on the metaphase II (MII) oocyte reactive oxygen species (ROS) level, mitochondrial transcription factor A (TFAM) expression and succinate dehydrogenase (SDH) activity. After collection of neonatal mouse ovaries, 45 ovaries were vitrified and the others (n = 45) were considered as control. All ovaries were cultured for seven days, and their isolated preantral follicles were cultured in three-dimensional culture system. After 12 days, the follicular development and oocyte maturation were evaluated and compared in vitrified and non-vitrified ovaries. The collected MII oocytes were inseminated with capacitated spermatozoa. Then, the fertilization, embryonic development, ROS level, TFAM gene expression and SDH activity of oocytes were assessed and compared. There was no significant difference between morphology and percentage of normal follicles between vitrified and non-vitrified ovaries at the beginning of culture. The follicular development and hormone level in the vitrified group was significantly lower than non-vitrified group and the ROS concentration in the vitrified group was significantly higher than non-vitrified group after one-week culture. After follicular culture, there was no significant difference in follicular development, oocyte maturation, fertilization rate, TFAM gene expression, ROS level and mitochondrial SDH activity between the groups. This study showed that ovarian tissue vitrification influences the follicular development through increase in ROS level during culture but these harmful effects may be recovered during the follicular culture period. Thus, vitrification and ovarian culture method should be improved.

Abstract
Objective The aim of present study is to determine the effects of supplementation of oocyte maturation medium with sodium
selenite (SS) on oocyte mitochondrial DNA (mtDNA) copy number and reactive oxygen species (ROS) levels.
Materials and Methods In this experimental study germinal vesicle (GV), metaphase I (MI), and metaphase II (MII)
stage oocytes were recovered from 6-8 week old female mice after superovulation. Some of the GV oocytes were
cultured and matured in the presence and absence of SS. Then in vivo and in vitro matured (IVM) oocytes were
subjected to mitochondria staining by MitoTracker green, ROS analysis, and mtDNA copy number determination using
absolute real-time polymerase chain reaction (PCR).
Results The maturation rate of GV oocytes to the MII stage significantly increased in the SS supplemented group
(79.25%) compared to the control group (72.46%, P<0.05). The intensity of mitochondrial staining was not different
among the studied groups, whereas the mitochondria distribution in the cytoplasm of the IVM oocytes showed some
aggregation pattern. The in vivo obtained MII oocytes had lower ROS levels and higher mtDNA copy numbers than
IVM-MII oocytes (P<0.05). The SS supplemented group had significantly lower ROS levels and higher mtDNA copy
numbers than the non-treated group (P<0.05).
Conclusion SS increased oocyte mtDNA copy number by decreasing oxidative stress. SS had an association with
better oocyte developmental competence.

Abstract
The effects of Morus nigra ethanolic extract, without or with addition of supplements associated or not with FSH, on in vitro culture of ovine secondary follicles were evaluated. In experiment 1, isolated secondary follicles were cultured for 12 days in α-MEM alone (control) or in different concentrations of M. nigra extract (MN 0.025; 0.05 or 0.1 mg/ml). In experiment 2, culture media were α-MEM supplemented with BSA, insulin, transferrin, selenium, glutamine, hypoxanthine and ascorbic acid (α-MEM+ ) or this medium associated with FSH (α-MEM+ + FSH), or 0.1 mg/ml M. nigra without supplements (MN 0.1) or supplemented (MN 0.1+ ) without or with FSH (MN 0.1+ + FSH). In experiment 1, 0.1 mg/ml M. nigra showed the highest percentages (p < .05) of normal follicles and fully grown oocytes, besides a higher follicular diameter than α-MEM and other M. nigra extract concentrations. Moreover, MN 0.1 showed lower (p < .05) glutathione (GSH) levels and similar (p > .05) mitochondrial activity compared to α-MEM. In experiment 2, MN 0.1+ + FSH showed similar results (p > .05) to α-MEM+ + FSH for all parameters evaluated, except for the daily growth rate, which was higher (p < .05) in MN 0.1+ + FSH. The GSH levels were higher in MEM+ than all treatments. In addition, oocytes from follicles cultured in MN 0.1+ + FSH showed ability to resume meiosis. In conclusion, M. nigra extract (0.1 mg/ml) added by supplements and FSH can be an efficient medium for ovine secondary follicle development.

Abstract
Broodiness causes reduced reproductive ability in poultry, but its regulatory mechanism remains poorly understood. ROS (reactive oxygen species) and autophagy are important for follicular development, and the interaction between the two may play a role in regulating broodiness. We examined goose follicles for ROS and oxidation scavenger activities during the egg-laying and broody stages. The follicular granulosa cells were exposed to media containing H2O2, and the interactions between ROS and autophagy in follicular granulosa cells in vitro were analyzed using a Western blot method. We found that the activities of superoxide dismutase (SOD) and lactate dehydrogenase (LDH) were enhanced and the amount of malondialdehyde (MDA) decreased in broody goose follicles. H2O2 inhibited the cell viability and induced autophagy. Furthermore, it was also found that H2O2 regulated autophagy by reducing mTOR and increasing p53; however, H2O2 had no impact on Beclin1 or ATG12. It was also shown that the enhanced autophagy lessened ROS-induced damages. We conclude that ROS and autophagy both played important roles in regulating follicular development to control broodiness in geese, and ROS activated autophagy in follicular granulosa cells via the mTOR pathway.

Abstract
Ovarian tissue cryopreservation together with follicle culture provides a promising technique for fertility preservation in cancer patients. The study aimed to evaluate follicle parameters in a culture medium supplemented with VEGFA165 and/or fetuin. Vitrified-warmed ovarian cortical pieces were divided randomly into four culture groups consisting of basic culture medium (control), and the basic culture medium supplemented with VEGFA165, fetuin or both. After six days of culture, we evaluated the following: percentage of resting, primary and secondary growing follicles; survival rate; steroid hormones production; levels of reactive oxygen species, lipid peroxidation and total antioxidant capacity; and developmental and antioxidant gene expression. The addition of VEGFA165 alone or in combination with fetuin to the culture medium caused resting follicle activation and increased the number of growing follicles. In the VEGFA165 group, we found a significant increase in the concentrations of 17β-estradiol at day 6 and progesterone from 4th day of the culture period. In the VEGFA165 + fetuin group, the concentration of 17β-estradiol rose at day 4 of the culture period. The levels of BMP15, GDF9 and INHB mRNAs were increased in all treated groups. In the fetuin and fetuin + VEGFA165 groups, we observed a high level of total antioxidant capacity and expression of SOD1 and CAT genes, low reactive oxygen species and lipid peroxidation levels and increased number of viable follicles. In conclusion, the present study provides useful evidence that supplementation of culture medium with VEGFA165 + fetuin leads to primordial follicle activation and development and increased percentage of healthy secondary growing follicles.

Abstract
AIM This study evaluated the antioxidant status of pre-antral follicles derived from vitrified ovaries pretreated with coenzyme Q10 (CoQ10). METHODS Mouse pre-antral follicles derived from fresh and vitrified warmed ovarian tissue were cultured with or without CoQ10 (50 μmol/L). Follicular growth, total antioxidant capacity (TAC), malondialdehyde (MDA) level, and superoxide dismutase (SOD), glutathione peroxidase (GPX), and catalase (CAT) activity during cultivation were assessed. RESULTS The growth rate of the fresh pre-antral follicles was higher compared with the vitrified groups, especially in the CoQ10-treated than non-treated groups. MDA increased while TAC decreased at 96 h of the cultivation period. TAC was higher while MDA was lower in the fresh pre-antral follicles than in the vitrified groups. These rates were higher in the CoQ10-treated than non-treated groups. The vitrified and fresh CoQ10-pretreated groups had significantly higher SOD, GPX, and CAT activity compared with the CoQ10 non-treated groups. CONCLUSION CoQ10-supplemented maturation medium can increase antioxidant enzyme activity and decrease lipid peroxidation in cultured pre-antral follicles derived from fresh and vitrified mouse ovaries.

Abstract
AIM The aim of this study was to evaluate the effects of preventive vitamin E (α-tocopherol) on antral follicle development and embryogenesis of oocytes obtained after vitrification of mouse ovarian tissue. METHODS Female Balb/c mice were killed by cervical dislocation after the injection of pregnant mare's serum gonadotrophin (10 IU) and their ovaries were randomly divided into three groups: control or non-vitrified (n = 10), vitrification 1 (5, 10% ethylene glycol + 5, 10% dimethylsulfoxide) (n = 15), and vitrification 2 (10, 15% ethylene glycol + 10, 15% dimethylsulfoxide) (n = 15) with ascending concentration of cryoprotectants. After toxicity tests and vitrification-warming, mechanically isolated antral follicles were cultured in α-minimum essential medium, which was supplemented with or without α-tocopherol (100 μM). The follicular maturation rates and embryo development were collected and assessed. Also, the viability, morphology and ultrastructure of derived antral follicles from vitrified ovaries were analyzed. RESULTS The morphology and ultrastructure of follicles were well preserved in the vitrified groups and α-tocopherol supplementation of culture media significantly increased the proportion of oocytes that reached metaphase II blastocyst rates compared to non-α-tocopherol supplemented media (P < 0.01). CONCLUSION Vitamin E improves in vitro maturation rates and blastocyst rates of oocytes that are isolated from vitrified ovarian tissue.

Abstract
Background Therapeutic potential of in vitro maturation (IVM) in infertility is growing with great promise. Although significant progress is obtained in recent years, existing
IVM protocols are far from favorable results. The first aim of this study was to investigate whether two step IVM manner change reactive oxygen species (ROS) and total anti-
oxidant capacity (TAC) levels. The second aim was to find the effect of alpha lipoic acid
(ALA) supplementation on oocyte maturation rate and on ROS/TAC levels during IVM. Materials and Methods In this experimental study, mouse germinal vesicle (GV) oocytes
divided into cumulus denuded oocytes (DOs) and cumulus oocyte complexes (COCs) groups.
GVs were matured in vitro in the presence or absence of ALA only for 18 hours (control) or
with pre-culture of forskolin plus cilostamide for an additional 18 hours. Matured oocytes obtained following 18 and 36 hours based on experimental design. In parallel, the ROS and TAC
levels were measured at different time (0, 18 and 36 hours) by 2',7'-dichlorodihydrofluorescein
(DCFH) probe and ferric reducing/antioxidant power (FRAP) assay, respectively. Results Maturation rate of COCs was significantly higher than DOs in control group
(P<0.05), while there was no significant difference between COCs and DOs when were
pre-cultured with forskolin plus cilostamide. ROS and TAC levels was increased and decreased respectively in DOs after 18 hours while in COCs did not change at 18 hours and
showed a significant increase and decrease respectively at 36 hours (P<0.05). ROS and
TAC levels in the presence of ALA were significantly decreased and increased respectively after 36 hours (P<0.05) whereas, maturation rates of COCs and DOs were similar
to their corresponding control groups. Conclusion ALA decreased ROS and increased TAC but could not affect maturation rate
of both COCs and DOs in one or two step IVM manner.

Abstract
In areas where soils are deficient in selenium (Se), dietary supplementation of this trace mineral directly to cattle is recommended. Selenium status affects fertility, and the form of Se supplemented to cows affects tissue-specific gene expression profiles. The objective of this study was to determine whether the form of Se consumed by cows would affect follicular growth and the production of steroids. Thirty-three Angus-cross cows that had ad libitum access of a mineral mix containing 35 ppm of Se in free-choice vitamin-mineral mixes as either inorganic (ISe), organic (OSe), or a 50/50 mix of ISe and OSe (MIX) for 180 days were used. After 170 days of supplementation, all cows were injected with 25-mg PGF2α to induce regression of the CL and then monitored for behavioral estrus (Day 0). From Day 4 to Day 8 after estrus, follicular growth was determined by transrectal ultrasonography. On Day 6, cows were injected with PGF2α (20 then 15 mg, 8-12 hours apart) to induce regression of the developing CL and differentiation of the dominant follicle of the first follicular wave into a preovulatory follicle. On Day 8, 36 hours after PGF2α (20 mg), the contents of the preovulatory follicle were aspirated by ultrasound-guided follicular puncture. Blood collected on Days 6 and 8 and follicular fluid collected on Day 8 was analyzed for concentrations of progesterone and estradiol. Form of Se supplemented to cows affected (P = 0.04) the systemic concentration of progesterone on Day 6, but not on Day 8. Form of Se did not affect the systemic concentration of estradiol on Day 6 or Day 8. Form of Se tended to affect (P = 0.07) the concentration of progesterone, but not that of estradiol, in the follicular fluid. Form of Se did not affect diameter of the dominant ovarian follicle on Days 4 to 6, but tended to affect (P = 0.08) the diameter of the preovulatory follicle on Day 8. Our results suggest that form of Se fed to cows affects the production of progesterone but not that of estradiol. Further investigation of organic Se-induced increases in progesterone and potentially the effects of increased progesterone on the establishment of pregnancy, especially in cows of lower fertility, is warranted.

Interaction between vitamin B6 and source of selenium on the response of the selenium-dependent glutathione peroxidase system to oxidative stress induced by oestrus in pubertal pig. J Trace Elem Med Biol 2015; 32:21-9. [PMID: 26302908 DOI: 10.1016/j.jtemb.2015.05.002] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/19/2015] [Revised: 04/29/2015] [Accepted: 05/12/2015] [Indexed: 10/23/2022]
Abstract
This study aimed to assess the interaction between vitamin B6 and selenium (Se) for the flow of Se towards the Se-dependent glutathione peroxidase (GPX) system in response to oxidative stress naturally induced by oestrus in a pubertal pig model. At first oestrus, forty-five gilts were randomly assigned to the experimental diets (n=9/group): basal diet (CONT); CONT+0.3mg/kg of Na-selenite (MSeB60); MSeB60+10mg/kg of HCl-B6 (MSeB610); CONT+0.3mg/kg of Se-enriched yeast (OSeB60); and OSeB60+10mg/kg of HCl-B6 (OSeB610). Blood samples were collected at each oestrus (long-term profiles), and daily from day -4 to +3 (slaughter) of the fourth oestrus (peri-oestrus profiles) after which liver, kidneys, and ovaries were collected. For long-term profiles, CONT had lower blood Se than Se-supplemented gilts (p<0.01) and OSe was higher than MSe (p<0.01). Lower erythrocyte pyridoxal-5-phosphate was found in B60 than B610 (p<0.01). No treatment effect was observed on GPX activity. For peri-oestrus profiles, treatment effects were similar to long-term profiles. Treatment effects on liver Se were similar to those for long-term blood Se profiles and OSe had higher renal Se concentrations than MSe gilts (p<0.01). Gene expressions of GPX1, GPX3, GPX4, and selenocysteine lyase in liver and kidney were greatest in OSeB610 gilts (p<0.05). These results suggest that dietary B6 modulate the metabolic pathway of OSe towards the GPX system during the peri-oestrus period in pubertal pigs.

Abstract
The antioxidant properties of Amburana cearensis extract may be a useful substitute for standard cell culture medium. Thus, the aim of this study was to evaluate the effect of this extract, with or without supplementation, on in vitro survival and development of sheep isolated secondary follicles. After collection of the ovaries, secondary follicles were isolated and cultured for 18 days in α-MEM+ supplemented with bovine serum albumin, insulin, transferrin, selenium, glutamine, hypoxanthine and ascorbic acid (control medium) or into medium composed of different concentrations of A. cearensis extract without supplements (Amb 0.1; 0.2 or 0.4 mg/ml) or A. cearensis extract supplemented with the same substances described above for α-MEM+ supplementation. The A. cearensis supplemented medium was named Amb 0.1+; 0.2+ or 0.4+ mg/ml. There were more morphologically normal follicles in Amb 0.1 or Amb 0.4 mg/ml than in the control medium (α-MEM+) after 18 days of culture. Moreover, the percentage of antrum formation was significantly higher in Amb 0.1 or Amb 0.2 mg/ml than in α-MEM+ and Amb 0.1+ mg/ml, and similar to the other treatments. All A. cearensis extract media induced a progressive and significant increase in follicular diameter throughout the culture period. In conclusion, this study showed that 0.1 mg/ml of this extract, without supplementation, maintains follicular survival and promotes the development of ovine isolated secondary follicles in vitro. This extract can be an alternative culture medium for preantral follicle development.

Improvement of development of equine preantral follicles after 6 days of in vitro culture with ascorbic acid supplementation. Theriogenology 2015; 84:750-5. [PMID: 26074067 DOI: 10.1016/j.theriogenology.2015.05.006] [Citation(s) in RCA: 33] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/13/2014] [Revised: 05/07/2015] [Accepted: 05/07/2015] [Indexed: 02/08/2023]
Abstract
The aim of this study was to evaluate the effects of different concentrations of ascorbic acid (25, 50, and 100 μg/mL) in supplemented minimum essential medium (MEM+) on the development of equine preantral follicles that were cultured in vitro for 2 or 6 days. The contralateral ovaries (n = 5) from five mares in seasonal anestrus were collected from a local abattoir. Nine ovarian tissue fragments of approximately 5 × 5 × 1 mm were obtained from each animal. One fragment was immediately fixed and subjected to histologic analysis (control group; Day 0), and the other eight were placed in PBS supplemented with penicillin (200 IU/mL) and streptomycin (200 mg/mL) at 4 °C for 1 hour (during transport to the laboratory). The fragments were cultured in situ for 2 days (D2) or 6 days (D6) in MEM+ or MEM+ plus ascorbic acid at three different concentrations, establishing the following nine groups: control; MEM+ (D2); MEM+ (D6); MEM+ 25 μg/mL of ascorbic acid (D2); MEM+ 25 μg/mL of ascorbic acid (D6); MEM+ 50 μg/mL of ascorbic acid (D2); MEM+ 50 μg/mL of ascorbic acid (D6); MEM+ 100 μg/mL of ascorbic acid (D2); and MEM+ 100 μg/mL of ascorbic acid (D6). The preantral follicles were classified according to their stage (primordial, primary, secondary, or antral) and their morphology (normal or abnormal). Slides (n = 951) including 4450 histologic sections were evaluated. Follicles were observed in only 4.85% (216 of 4450) of the histologic sections. Of the 407 follicles evaluated, 120 were in the primordial stage and 287 were in different developmental stages; additionally, 43.5% were morphologically normal. After 6 days of culture, the groups cultured with 50 and 100 μg/mL of ascorbic acid differed in terms of follicular development compared with the other groups. On the basis of occurrence of follicular development and the presence of viable follicles, it can be concluded that a positive effect of culture for 6 days in MEM+ supplemented with 50 and 100 μg/mL of ascorbic acid was observed on equine ovarian fragments.

Abstract
CONTEXT It is now clear that oxidative stress (OS) and chronic low-grade inflammation are two main pathways involved in polycystic ovary syndrome (PCOS) pathogenesis. Therefore, simultaneous targeting of these pathways by means of carvedilol and Semelil (ANGIPARS™), as established medicines with dual anti-cytokine and anti-oxidant potential may be a therapeutic alternative approach to the current treatments. OBJECTIVE The objective of this study is to study the protective effects of carvedilol and ANGIPARS™ on inflammatory and oxidative response in hyperandrogenism-induced polycystic ovary (PCO). MATERIALS AND METHODS The murine model of PCO was induced by letrozole (1 mg/kg/d; orally) and effective doses of carvedilol (10 mg/kg/d; orally) and ANGIPARS™ (2.1 mg/kg/d; orally) were administrated for 21 d in PCO and non-PCO healthy rats. Ovarian folliculogenesis, sex hormones concentrations, OS, inflammatory, and metabolic biomarkers were assessed in serum and ovaries. RESULTS PCO rats exhibited ovarian cystogenesis which was preserved by the application of carvedilol and ANGIPARS™. In comparison with controls, decreased level of the total antioxidant power (TAP) and higher levels of reactive oxygen species (ROS) and lipid peroxidation (LPO) in serum and ovaries (2.41 ± 0.67 versus 0.72 ± 0.11; and 0.17 ± 0.04 versus 0.05 ± 0.01; 5.48 ± 1.30 versus 10.56 ± 0.77; and 7.06 ± 1.94 versus 17.98 ± 0.98; p < 0.05, respectively) were detected in PCO rats. Moreover, the PCO rats exhibited hyperandrogenism due to a 3.7-fold increase in serum testosterone concentration (35.04 ± 3.17 versus 131.09 ± 13.24; p < 0.05) along with a 2.98-fold decrease in serum progesterone (6.19 ± 0.40 versus 18.50 ± 1.03; p < 0.05) and 5.2-fold decrease in serum estradiol (9.30 ± 0.61 versus 48.3 ± 2.10; p < 0.05) when compared with those of the control group. However, similar to the control group, normal levels of OS markers and sex hormones were detected in ANGIPARS™ and carvedilol co-treated PCO rats. Besides, when compared with controls, increased levels of TNF-α (770.75 ± 42.06 versus 477.14 ± 28.77; p < 0.05) and insulin (1.27 ± 0.10 versus 0.36 ± 0.05; p < 0.05) in PCO rats were significantly inhibited by carvedilol and ANGIPARS™ co-treatment. DISCUSSION AND CONCLUSION We evidenced the beneficial effects of carvedilol and ANGIPARS™ in PCO, which underpin the new alternative approach in using these kinds of medicines in female reproductive disorders.

Comparison of oxidative status of mouse pre-antral follicles derived from vitrified whole ovarian tissue and vitrified pre-antral follicles in the presence of alpha lipoic acid. J Obstet Gynaecol Res 2015; 40:1680-8.

Abstract
AIM The main goal of this study was to compare developmental competence and oxidative status of vitrified-warmed pre-antral follicles (VPF) with pre-antral follicles derived from vitrified-warmed ovarian tissue (VOF) in the presence of alpha lipoic acid (ALA). MATERIALS AND METHODS Ovarian tissue and isolated pre-antral follicles were exposed to equilibration solution and then vitrification solution. After thawing of LN2 snap-frozen samples, pre-antral follicles were cultured with or without ALA for 12 days that followed by hCG-induced ovulation. MII oocytes were in vitro fertilized and embryo cleavage assessed. Reactive oxygen species (ROS) and total antioxidant capacity (TAC) levels of cultured pre-antral follicles were measured. RESULTS The rates of survival, antral-like cavity formation, MII oocytes, fertilization, 2-cell embryo and blastocyst development were higher in VPF compared to VOF. These rates were higher in ALA-supplemented groups in comparison to their respective groups. An increase and a decrease in ROS production and TAC levels were observed up to the 96 h during cultivation period, respectively. ROS level was lower in cultured VPF compared to VOF. In ALA-treated groups, ROS level decreased to reach comparable values of starting point and TAC levels increased after 24 h of culture and then remained constant. CONCLUSION Developmental outcomes showed vitrification of pre-antral follicles is more appropriate method than that of whole ovarian tissue. Moreover, it seems that inclusion of ALA improved in vitro development of pre-antral follicles in both vitrified and non-vitrified samples.

Abstract
In present study, we sought to examine the ability of preimplantation bovine embryos to activate the NF-E2-related factor 2 (NRF2)-mediated oxidative-stress response under an oxidative stress environment. In vitro 2-, 4-, 8-, 16-cell-, and blastocyst-stage embryos were cultured under low (5%) or high (20%) oxygen levels. The expression of NRF2, KEAP1 (NRF2 inhibitor), antioxidants downstream of NRF2, and genes associated with embryo metabolism were analyzed between the embryo groups using real-time quantitative PCR. NRF2 and KEAP1 protein abundance, mitochondrial activity, and accumulation of reactive oxygen species (ROS) were also investigated in blastocysts of varying competence that were derived from high- or low-oxygen levels. The expression levels of NRF2 and its downstream antioxidant genes were higher in 8-cell, 16-cell, and blastocyst stages under high oxygen tension, whereas KEAP1 expression was down-regulated under the same conditions. Higher expression of NRF2 and lower ROS levels were detected in early (competent) blastocysts compared to their late (noncompetent) counterparts in both oxygen-tension groups. Similarly, higher levels of active nuclear NRF2 protein were detected in competent blastocysts compared to their noncompetent counterparts. Thus, the survival and developmental competence of embryos cultured under oxidative stress are associated with activity of the NRF2-mediated oxidative stress response pathway during bovine pre-implantation embryo development.

Abstract
The aim of this study was to investigate the effect of ovarian tissue transportation conditions (medium and period of time) on the morphology, apoptosis and development of ovine preantral follicles cultured in vitro. Each ovarian pair was cut into nine slices, with one fragment being fixed immediately (fresh control). The remaining fragments were placed individually in cryotubes containing conservation medium (minimal essential medium (MEM) without supplementation or MEM+ - with supplementation) and stored at 35ºC for 6 or 12 h without (non-cultured) or with subsequent culture for 5 days. Then, the fragments were processed for histological and terminal deoxynucleotidyl transferase (TdT) mediated dUTP nick-end labelling (TUNEL) examination. Preservation of ovarian slices in MEM or MEM+ (non-cultured) resulted in similar percentages of normal follicles when compared with the fresh control. Nevertheless, compared with the fresh control, a decrease in the percentage of normal follicles was observed in tissues cultured for 5 days. Only for tissues preserved in supplemented medium (MEM+) for 6 h, the percentage of TUNEL positive cells was similar between non-cultured tissues and tissues cultured for 5 days. Follicular activation and growth (follicular and oocyte diameter) were higher in cultured tissues than in fresh control or non-cultured tissues, except those from fragments preserved for 6 h in MEM and then cultured for 5 days in which no growth was observed. In conclusion, ovine ovarian tissue was successfully preserved in supplemented medium (MEM+) at a temperature close to physiological values (35°C) for up to 6 h without affecting apoptosis in the ovarian follicles and their ability to develop in vitro.
