Abstract
In the current study, we examined: 1) the agreement (bias) between fluorescence-based methods (NucleoCounter-SP100 [NC] vs. flow cytometry [FC]) for determining the viability (VIAB) of frozen/thawed stallion sperm; 2) the agreement between post-thaw sperm total motility (TMOT) and VIAB; 3) whether a difference between TMOT and VIAB [VIAB - TMOT] in frozen/thawed stallion sperm could be explained by the level of lipid peroxidation in viable sperm (VLPP); 4) the repeatability of post-thaw analysis of sperm quality; and 5) the effect of final post-thaw semen dilution (10, 30, or 50 x 106 sperm/mL) on sperm motion characteristics. Post-thaw VIAB was similar between NC and FC (P > 0.05), and the agreement between these two methods was high (bias: 1 to -3). The agreement between post-thaw TMOT and VIAB decreased as the pre-freeze percentages of morphologically normal sperm and DNA quality decreased: bias - 4 to - 25. The bias between [VIAB - TMOT] and VLPP ranged from - 5 to 7. Differences in post-thaw sperm quality (TMOT, PMOT, VIAB, and sperm concentration) were not observed when analyzing one or three straws per ejaculate (P > 0.05). There was no effect of post-thaw sperm concentration (i.e., 10 vs. 30 vs. 50 x 106 sperm/mL) on sperm motion characteristics (P > 0.05). This study reports factors other than post-thaw sperm motility that warrant further consideration when analyzing frozen/thawed stallion sperm.

Ovine fertility by artificial insemination in the breeding season could be affected by intraseasonal variations in ram sperm proteomic profile. Theriogenology 2023; 208:28-42. [PMID: 37290145 DOI: 10.1016/j.theriogenology.2023.05.030] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2023] [Revised: 04/24/2023] [Accepted: 05/30/2023] [Indexed: 06/10/2023]
Abstract
It is important to note that seasonality could affect ram reproductive parameters, and therefore, fertility results after artificial insemination. In this work, 1) we assessed fertility rates after cervical artificial insemination of 11,805 ewes at the beginning (June 21st to July 20th) and at the end (November 20th to December 21st) of the reproductive season in the Assaf breed for the last four years, and 2) we aimed to identify male factors influencing the different reproductive success obtained depending on the time at the mating season in which ovine artificial insemination was performed. For this purpose, we evaluated certain ram reproductive and ultrasonographical parameters as well as we performed a multiparametric and proteomic sperm analysis of 6-19 rams at two very distant points in the mating season (July as Early Breeding Season -EBS- and November as Late Breeding Season -LBS-). Rutinary assessments carried out in the ovine reproduction centers (testicular volume, libido, sperm production and mass motility) showed non-significant differences (P ≥ 0.05) between both studied times, as well as the ram ultrasonographic evaluation (Resistive and Pulsatility Index as Doppler parameters; and pixels mean gray level, and hypoechoic areas percentage and density as echotexture parameters). However, at level of sperm functionality, although sperm quality appeared non-significantly lower (P ≥ 0.05) in the EBS, we identified a significantly different (P < 0.05) sperm proteomic profile between the seasonality points. The following proteins were identified with the lowest abundance in the EBS with a fold change > 4, a P = 2.40e-07, and a q = 2.23e-06: Fibrous Sheath-Interacting Protein 2, Disintegrin and Metalloproteinase Domain-Containing Protein 20-like, Phosphoinositide-Specific Phospholipase C, Tektin 5, Armadillo Repeat-Containing Protein 12 Isoform X3, Solute Carrier Family 9B1, Radial Spoke Head Protein 3 Homolog, Pro-Interleukin-16, NADH Dehydrogenase [Ubiquinone] 1 Alpha Subcomplex Subunit 8, Testis, Prostate and Placenta-Expressed Protein, and Acyl Carrier Protein Mitochondrial. In conclusion, while our basic analyses on male and sperm quality showed similar results between the beginning and the end of the breeding season, on a proteomic level we detected a lower expression of sperm proteins linked to the energy metabolism, sperm-oocyte interactions, and flagellum structure in the EBS. Probably, this different protein expression could be related to the lower fertility rate of Assaf ewes after cervical artificial insemination at this time. More importantly, sperm proteins can be used as highly effective molecular markers in predicting sperm fertilization ability related to intraseasonal variations.

Acta Vet Scand 2021; 63:42. [PMID: 34736507 PMCID: PMC8567708 DOI: 10.1186/s13028-021-00609-8] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2021] [Accepted: 10/24/2021] [Indexed: 12/20/2022] Open
Abstract
Background Centrifugation is routinely employed in handling the ejaculates of some species, but it is not part of the commonly used protocols in ram. However, the development and implementation of new assisted reproductive technologies, alternative preservation models based on washing sperm from a cellular ageing-accelerating substance such as the seminal plasma, and basic studies in spermatology is associated with the use of centrifugation. This requires a specific evaluation of the centrifugation protocols considering the species-specific relationship with the potential damage produced by this procedure. No previous studies have determined the effect of different centrifugation forces on ram sperm. Therefore, we aimed to assess the performance of three centrifugal forces (600×g, 3000×g, and 6000×g for 10 min at room temperature) and their effects on ram sperm motility and functionality. Results Sperm motility and functionality parameters were assessed at 0 h and after 2 h of incubation at 37 °C. As expected, a higher cell packaging degree was obtained at high centrifugation forces (P ≤ 0.0001). Cell packaging was unstable at all centrifugal forces. Thus, there was a high cell resuspension rate after less than 2 min. Regarding sperm quality, there was a change in movement pattern of 3000×g and 6000×g centrifuged sperm after 2 h of incubation at 37 °C, characterized by an increase in rapid progressive motility, linearity, straightness, and beat frequency, and a decrease in medium progressive motility, curvilinear velocity, path velocity, and head lateral amplitude. Non-significant differences were obtained among the different treatments concerning the total viability. However, we observed a significant increase (P ≤ 0.05) in the percentage of viable apoptotic sperm in the samples centrifuged at 6000×g at 0 h. Conclusions Centrifugal forces equal to or greater than 3000×g induced some deleterious effects in ram sperm quality, and lower forces did not provide a successful cell packaging degree.

Abstract
Reactive oxygen species (ROS) induced by high glucose and high fat of diabetes mellitus (DM) finally caused the occurrence and progression of atherosclerosis and other macrovascular complications. Paeonol (Pae) exhibits anti-inflammation, antioxidation, and antiatherosclerosis activities. However, the role of Pae in diabetic cardiopathy has not been fully understood. Therefore, we aimed to investigate the role of Pae in diabetic cardiovascular diseases. Human umbilical vein endothelial cells (HUVECs) were exposed to high glucose and palmitic acid (HG/HP), a model DM environment and different doses of Pae. The viability and apoptotic rate of HUVECs were assessed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide and flow cytometry assay, respectively. Oxidative indicators (ROS, malondiadehyde [MDA], superoxide dismutase [SOD]), and inflammatory cytokines (tumor necrosis factor-α, interleukin-1β, and interleukin-6) were detected by 2,7-dichlorodihydrofluorescein diacetate, colorimetry, and enzyme-linked immunosorbent assay. The protein levels of Sirtuin type 1 (SIRT1), Bcl-2, Bax, Cleaved caspase-3, p-p65, and p-65 were detected by Western blot. The mRNA levels of Bcl-2 and Bax were detected by quantitative real-time polymerase chain reaction. The acetylation and protein levels of forkhead box O3a (FOXO3a) were detected by immunoprecipitation assay. SIRT1 silencing was used to confirm the role of Pae in the resistance to apoptosis, oxidative stress, and inflammatory response. Pae increased SIRT1 expression, cell viability, and SOD activity and suppressed apoptosis, the levels of p-p65/p-65, ROS, MDA, and inflammatory cytokines, and the expression of acetylated-FOXO3a induced by HG/HP in HUVECs. SIRT1 silencing abrogated the effect of Pae on HG/HP-mediated HUVECs. Inhibitory effect of Pae on apoptosis, oxidative stress, and inflammatory response in HUVECs induced by HG/HP induced through regulating SIRT1/FOXO3a/NF-κB pathway.

Abstract
Cryopreservation of semen and artificial insemination have an important, positive impact on cattle production, and product quality. Through the use of cryopreserved semen and artificial insemination, sperm from the best breeding bulls can be used to inseminate thousands of cows around the world. Although cryopreservation of bull sperm has advanced beyond that of other species, there are still major gaps in the knowledge and technology bases. Post-thaw viability of sperm is still low and differs significantly among the breeding bulls. These weaknesses are important because they are preventing advances both in fundamental science of mammalian gametes and reproductive biotechnology. Various extenders have been developed and supplemented with chemicals to reduce cryodamage or oxidative stress with varying levels of success. More detailed insights on sperm morphology and function have been uncovered through application of advanced tools in modern molecular and cell biology. This article provides a concise review of progress in the cryopreservation of bull sperm, advances in extender development, and frontiers using diverse techniques of the study of sperm viability. This scientific resource is important in animal biotechnology because with the advances in discovery of sperm fertility markers, there is an urgent need to improve post-thaw viability and fertility of sperm through enhanced cryopreservation for precision agriculture to produce food animals to ensure food security on the global scale.

Rosiglitazone in the thawing medium improves mitochondrial function in stallion spermatozoa through regulating Akt phosphorylation and reduction of caspase 3. PLoS One 2019; 14:e0211994.

Abstract
BACKGROUND The population of stallion spermatozoa that survive thawing experience compromised mitochondrial functionality and accelerated senescence, among other changes. It is known that stallion spermatozoa show very active oxidative phosphorylation that may accelerate sperm senescence through increased production of reactive oxygen species. Rosiglitazone has been proven to enhance the glycolytic capability of stallion spermatozoa maintained at ambient temperature. OBJECTIVES Thus, we hypothesized that thawed sperm may also benefit from rosiglitazone supplementation. MATERIALS AND METHODS Thawed sperm were washed and resuspended in Tyrodes media, and the samples were divided and supplemented with 0 or 75 μM rosiglitazone. After one and two hours of incubation, mitochondrial functionality, Akt phosphorylation and caspase 3 activity were evaluated. Additional samples were incubated in the presence of an Akt1/2 inhibitor, compound C (an AMPK inhibitor) or GW9662 (an antagonist of the PPARγ receptor). RESULTS Rosiglitazone maintained Akt phosphorylation and reduced caspase 3 activation (p<0.01), both of which were prevented by incubation in the presence of the three inhibitors. Rosiglitazone also enhanced mitochondrial functionality (P<0.01). CONCLUSION We provide the first evidence that the functionality of frozen stallion spermatozoa can be potentially improved after thawing through the activation of pro survival pathways, providing new clues for improving current sperm biotechnology.
