Theriogenology 2024; 223:98-107. [PMID: 38697014 DOI: 10.1016/j.theriogenology.2024.04.020] [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: 09/06/2023] [Revised: 04/25/2024] [Accepted: 04/29/2024] [Indexed: 05/04/2024]
Abstract
The ALDH1A1 gene encodes a cytoplasmic member of the aldehyde dehydrogenase 1 family, which plays an important role in regulating animal reproductive performance, including estrus cycle and embryonic development. The aim of this study was to characterize ALDH1A1 activity in ovaries of 3-5 year-old yaks and to determine its effects on cell proliferation, apoptosis, and progesterone secretion in luteal cells (LCs). The coding sequence (CDS) of the ALDH1A1 gene was cloned by reverse transcription-PCR and immunohistochemical analysis was used to confirm localization of the ALDH1A1 protein in the ovary. To assess the activity of ALDH1A1 in regulating progesterone secretion, si-ALDH1A1 was transfected into LCs in vitro and progesterone levels in LC supernatants were measured by ELISA. The interference efficiency was assessed by real-time quantitative PCR (RT-qPCR) and immunofluorescence staining, and cell proliferation and apoptosis were evaluated by EdU and TUNEL staining, respectively. The cloned ALDH1A1 sequence contained 1462 bp, encoding 487 amino acids. Immunohistochemical analysis showed that ALDH1A1 protein expression, which was significantly higher in LCs, was mainly found in antral follicles and the corpus luteum (CL). The expression of ALDH1A1 mRNA in LCs was effectively inhibited by si-ALDH1A1transfection, and progesterone secretion was markedly decreased along with the significant down-regulation of progesterone pathway-related genes, STAR, CYP11A1, CYP19A1, CYP17A1, 3β-HSD, and HSD17B1. Knockdown of ALDH1A1 mRNA expression decreased cell proliferation and increased apoptosis in LCs. The mRNA expression of the proliferation-related genes, PCNA, CCND1, CCNB1 and CDC25A, was significantly down-regulated, while expression of the apoptosis-promoting CASP3 gene was significantly increased. In summary, we characterized the yak ALDH1A1 gene and revealed that ALDH1A1 knockdown promoted apoptosis, repressed cell proliferation, and decreased progesterone secretion by yak LCs, potentially by regulating the mRNA expression of genes related to proliferation, apoptosis, and progesterone synthesis and secretion.

Abstract
The aims of this study were to analyse the protein phosphatase 1 regulatory subunit 11 (PPP1R11) expression and cellular localization in yak follicles and investigate its effects on cell proliferation, apoptosis and oestrogen secretion in granulosa cells (GCs). Ten healthy and non-pregnant female yaks (4-year-old) were used as experimental animals. The mRNA relative expression level of PPP1R11 in GCs from small (<3.0 mm), medium (3.0-5.9 mm) and large (6.0-9.0 mm) follicles was detected by RT-qPCR, and the cellular localization of PPP1R11 protein was detected by immunohistochemistry staining (IHC). After isolation, culture and identification of yak GCs in vitro, si-PPP1R11 and si-NC (negative control) were transfected into GCs. RT-qPCR and immunofluorescence staining were used to evaluate the interference efficiency, and ELISA was performed to detect oestrogen concentration. Then, EdU staining and TUNEL staining were conducted to analyse cell proliferation and apoptosis. In addition, the oestrogen synthesis, proliferation- and apoptosis-related genes were detected by RT-qPCR after knockdown PPP1R11. The results showed that PPP1R11 is mainly located in ovarian GCs, and the expression levels of PPP1R11 in GCs from large follicles were significantly higher than that from medium and small follicles. Transfection of si-PPP1R11 into GCs could significantly inhibit the expression of PPP1R11. Interestingly, the oestrogen secretion ability and the expression level of oestrogen pathway-related genes (STAR, CYP11A1, CYP19A1 and HSD17B1) were also significantly downregulated. Moreover, the proportion of positive cells was decreased, and cellular proliferation-related genes (PCNA, CCNB1 and CDC25A) were significantly downregulated after knockdown PPP1R11. However, the proportion of apoptotic cells was increased, and apoptosis-related genes (BAX, CASP3 and P53) were significantly upregulated. Taken together, this study was the first revealed the expression and cellular localization of PPP1R11 in yak follicles. Interference PPP1R11 could reduce oestrogen secretion, inhibit proliferation and promote apoptosis in GCs, which provided a basis for further studies on the regulatory mechanism of PPP1R11 in follicle development.

Leukemia inhibitory factor enhances the development and subsequent blastocysts quality of yak oocytes in vitro. Front Vet Sci 2022; 9:997709. [PMID: 36213393 PMCID: PMC9533679 DOI: 10.3389/fvets.2022.997709] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2022] [Accepted: 08/22/2022] [Indexed: 11/25/2022] Open
Abstract
Leukemia inhibitory factor (LIF) is a multipotent cytokine of the IL-6 family which plays a critical role in the maturation and development of oocytes. This study evaluated the influence of LIF on the maturation and development ability of yak oocytes, and the quality of subsequent blastocysts under in vitro culture settings. Different concentrations of LIF (0, 25, 50, and 100 ng/mL) were added during the in vitro culture of oocytes to detect the maturation rate of oocytes, levels of mitochondria, reactive oxygen species (ROS), actin, and apoptosis in oocytes, mRNA transcription levels of apoptosis and antioxidant-related genes in oocytes, and total cell number and apoptosis levels in subsequent blastocysts. The findings revealed that 50 ng/mL LIF could significantly increase the maturation rate (p < 0.01), levels of mitochondria (p < 0.01) and actin (p < 0.01), and mRNA transcription levels of anti-apoptotic and antioxidant-related genes in yak oocytes. Also, 50 ng/mL LIF could significantly lower the generation of ROS (p < 0.01) and apoptosis levels of oocytes (p < 0.01). In addition, blastocysts formed from 50 ng/mL LIF-treated oocytes showed significantly larger total cell numbers (p < 0.01) and lower apoptosis rates (p < 0.01) than the control group. In conclusion, the addition of LIF during the in vitro maturation of yak oocytes improved the quality and the competence of maturation and development in oocytes, as well as the quality of subsequent blastocysts. The result of this study provided some insights into the role and function of LIF in vitro yak oocytes maturation, as well as provided fundamental knowledge for assisted reproductive technologies in the yak.

Abstract
High-quality oocytes are a prerequisite for successful fertilization. Mammals feeding on aflatoxin-contaminated feed can cause reproductive toxicity, including follicular atresia, poor oocyte development and maturation, and aberrant epigenetic modifications of oocytes. In addition, the important role of ascorbic acid (AA) in reproductive biology has been confirmed, and AA is widely used as an antioxidant in cell culture. However, the toxic effects of aflatoxin B1 (AFB1 ) on yak oocytes and whether AA has protective effects remain unknown. In this study, we found that exposure to AFB1 impedes meiotic maturation of oocytes, promotes apoptosis by triggering high levels of reactive oxygen species (ROS), and disrupts mitochondrial distribution and actin integrity, resulting in a decrease in the fertilization ability and parthenogenetic development ability of oocytes. In addition, these injuries changed the DNA methylation transferase transcription level of mature oocytes. After adding 50 μg/ml AA, the indices recovered to levels close to those of the control group. The results showed that AA could protect yak oocytes from the toxic effects of AFB1 and improve the quality of oocytes.

Abstract
BACKGROUND Protein malnutrition remains a severe problem in ruminant production and can increase susceptibility to infection, especially during the growth stage. This study aimed to explore substituting soybean meal with corn on activation of the TLR pathway and potential impact on immune response bias towards Type 1 or Type 2 using growing female goats as experimental animals. METHODS Twenty-four Xiangdong black goats (initial BW = 19.83 ± 0.53 kg, about 8 ± 0.3 months old) were selected and randomly divided into the corn-soybean meal basal diet group (CON, 10.77% protein) and replacing soybean meal with 100% of corn group (CRS, 5.52% protein). EDTA whole blood and serum samples were collected prior to slaughter for determinations of blood cell counts, anti-inflammatory cytokines and antibodies. The duodenum, jejunum, ileum and colon tissues were collected after formal trial to study the effect of CRS diet on the expression of TLR4 pathway. RESULTS Our results showed CRS diet did not induce a significant change in immune function, as evidenced by the observations that white blood cell (WBC), neutrophil (Neu), lymphocyte (Lym), monocyte (Mon), eosinophil (Eos), interleukin-4 (IL-4), IL-5, IL-13, immunoglobin G (IgG), IgA, and IgM levels in serum were similar between the two groups. RT-PCR results showed the expression of tumor necrosis factor-α (TNF-α) (P < 0.01) and interferon-β (IFN-β) (P < 0.01) were up-regulated in the colon of goats in the CRS group. No differences in the expression of myeloid differentiation factor 88 (MyD88) adaptor-like protein (TIRAP), IL-1 receptor-associated kinase 1 (IRAK1), TNF receptor related factor 6 (TRAF6), NF-kappa B (NF-κB), mitogen-activated protein kinase 1 (MAPK1) or activator protein-1 (AP-1) in the TLR4/MyD88 dependent pathway were observed between the two groups for any of the tested tissue. However, the expression of NF-κB activator (TANK) binding kinase 1 (TBK1) in TLR4/MyD88 independent pathway was up-regulated in the duodenum and colon (P < 0.01), and the expression of interferon regulatory factor-3 (IRF3) was up-regulated (P < 0.01) in colon. CONCLUSIONS Our results suggested that the CRS diet failed to induce a significant change in innate immunity and adaptive immunity in growing goats. However, the up-regulated TBK1 and IRF3 in the colon from the CRS goats suggests that the CRS diet may induce the expression of Th1-type proinflammatory cytokines and inflammatory response through a TLR4-MyD88-independent pathway, and the colon may be the easiest targeted section in the intestinal tract.

Abstract
This study was designed to examine the effects of seminal insulin-like growth factor-1 (IGF-1) supplementation on structural and functional properties of buffalo sperm post cryopreservation. Semen ejaculates from buffalo bulls (n = 6) were proportioned into four aliquots and diluted with egg yolk-based extender. Prior to equilibration, IGF-1 was added to extender as four treatments: group IGF0 (no supplementation), IGF150 (150 ng/mL), IGF250 (250 ng/mL) and IGF350 (350 ng/mL). The extended semen was transferred into 0.25 mL mini-straws, equilibrated (4 °C at 4 h), and cryopreserved. Total sperm motility was greater (P < 0.05) when there was the IGF150 treatment compared with values for other groups. Furthermore, with the IGF150 treatment there was the least and greatest (P < 0.05) mitochondrial superoxide status and membrane potential, respectively. Similarly, with the IGF150 treatment there was a greater (P < 0.05) sperm membrane integrity with a lesser (P < 0.05) calcium status compared to values for the other groups. In conclusion, seminal IGF-1 supplementation affects the structural and functional properties of buffalo sperm following cryopreservation.

Evidence that extrapancreatic insulin production is involved in the mediation of sperm survival. Mol Cell Endocrinol 2021; 526:111193. [PMID: 33610643 DOI: 10.1016/j.mce.2021.111193] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/18/2020] [Revised: 01/26/2021] [Accepted: 01/29/2021] [Indexed: 12/13/2022]
Abstract
Evidence is presented for expression of the insulin receptor on the surface of mammalian spermatozoa as well as transcripts for the receptor substrate adaptor proteins (IRS1-4) needed to mediate insulin action. Exposure to this hormone resulted in insulin receptor phosphorylation (pTyr972), activation of AKT (pSer473) and the stimulation of sperm motility. Intriguingly, the male germ line is also shown to be capable of generating insulin, possessing the relevant mRNA transcript and expressing strong immunocytochemical signals for both insulin and C-peptide. Insulin could be released from the spermatozoa by sonication in a concentration-dependent manner but was not secreted in response to glucose, fructose or stimulation with progesterone. However, insulin release could be induced by factors present in human uterine lavages. Furthermore, the endometrium was also shown to possess the machinery for insulin production and action (mRNA, insulin, C-peptide, proprotein convertase and insulin receptor), releasing insulin into the uterine lumen prior to ovulation. These studies emphasize the fundamental importance of extra-pancreatic insulin in regulating the reproductive process, particularly in the support of spermatozoa on their perilous voyage to the site of fertilization.

Abstract
The estrogen-signalling pathway is critical for normal follicular development; however, little is known about its importance during in vitro maturation (IVM) in large animals, particularly yaks (Bos grunniens). Through the present study, we aimed to determine the mechanisms underlying estrogen involvement in cumulus expansion and the subsequent development of cumulus-oocyte complexes (COCs). COCs were cultured in the maturation medium supplemented with different concentrations (10−6–10−3 mM) of 17β-estradiol (E2) or its receptor antagonist, fulvestrant, and quantitative reverse-transcription polymerase chain reaction (qRT-PCR) and western blot were performed to determine the expression of cumulus-expansion related factors and oocyte-secreted factors (OSFs). The cumulus expansion of COCs was observed using an inverted microscope, and COCs developmental ability were judged by the evaluation of cleavage and blastulation rates per inseminated oocytes by IVF, and the number of cells in the blastocyst. Cumulus expansion increased with 10−6–10−3 mM E2, but decreased with fulvestrant. HAS2, PTGS2, PTX3 and OSFs expression increased in the 10−6–10−3 mM E2 groups. Significantly higher cleavage and blastocyst rates were observed in the 10−4 mM E2 group than in the fulvestrant and 0 mM E2 groups. Moreover, in the 10−4 mM group, blastocysts at 7 days had higher cell counts than the other groups. In conclusion, the increase in cumulus expansion and subsequent oocyte development after the addition of E2 to IVM medium may have resulted from increased cumulus-expansion-related factor expression and OSF levels.

Abstract
The fusion of sperm and oocytes determines the fertilization competence and subsequent development of embryos, which, in turn, can be affected by various proteins and DNA methylation. However, several factors in this whole regulation process remain unknown, especially in yaks. Here, we report that fibroblast growth factor 10 (FGF10) is an important growth factor that can enhance the maturation rate of yak oocytes and the motility of frozen spermatozoa. Subsequent blastocyst quality was also improved by increasing the total cell number and level of pregnancy-associated protein in blastocysts. These effects were significantly high in the group that received the 5 ng/ml FGF10 treatment, during both in vitro maturation (IVM) and capacitation. Our data show that the effects of FGF10 were dose-dependent at vital steps of embryogenesis in vitro. Furthermore, quantitative polymerase chain reaction, western blot analysis, and immunofluorescence demonstrated that the levels of CD9, CD81, DNMT1, and DNMT3B in both mature cumulus-oocyte complexes and capacitated sperms were regulated by FGF10, which was also highly expressed in the group treated with 5 ng/ml FGF10 during both IVM and capacitation. From our present study, we concluded that FGF10 promotes yak oocyte fertilization competence and subsequent blastocyst quality, and could also regulate CD9, CD81, DNMT1, and DNMT3B to optimize sperm-oocyte interactions and DNA methylation during fertilization.

Abstract
DNA methylation as an important, essential epigenetic modification is critical for the successful development of mammalian embryos. In recent years, the important role of ascorbic acid (AA) as an irreplaceable cofactor for epigenetic regulation has been confirmed. However, the effect of AA on DNA methylation in preimplantation embryo development of plateau yak remains unknown. In this study, we explored whether AA can help regulates DNA methylation in yak preimplantation embryos to improve the blastocyst quality. First, our results indicate that the preimplantation of the yak still follows the classical pattern of DNA demethylation and remethylation, however, remethylation occurs in the blastocyst stage. Second, the unique expression pattern of the ten-eleven translocation enzyme (TET3) in the cytoplasm plays a key role in the demethylation mechanism. Third, in the blastocyst stage, the pluripotency gene CDX2 promoter region was in a hypomethylated state, and the POU5F1, SOX2, and NANOG promoter regions were in moderate methylation states. In addition, treatment with 50 μg/ml AA mainly improved the expression levels of DNMT1, DNMT3a, and TET3, ensured the establishment, maintenance and transition of 5-methylcytosine. After AA treatment, the methylation level of the pluripotency genes NANOG promoter regions was significantly reduced, and the mRNA transcript abundance of the pluripotency genes NANOG, POU5F1, and CDX2 was upregulated. In conclusion, our findings suggest that AA could increase blastocyst cell numbers by regulating DNA methylation of yak preimplantation embryos .

Abstract
SummaryMelatonin plays a critical role in several types of cells as an antioxidant to protect intracellular molecules from oxidative stress. The anti-oxidation effect of melatonin in yak embryos is largely unknown. We report that melatonin can protect the development of yak preimplantation embryos against oxidative stress induced by hydrogen peroxide (H2O2). Therefore, the quality of blastocysts developed from zygotes exposed to H2O2 was promoted. In addition, we observed that melatonin reduced H2O2-induced intracellular reactive oxygen species (ROS) levels and prevented mitochondrial dysfunction in zygotes. These phenomena revealed the effective antioxidant activity of melatonin to prevent oxidative stress in yak embryos. To determine the underlying mechanism, we further demonstrated that melatonin protected preimplantation embryos from oxidative damage by preserving antioxidative enzymes. Collectively, these results confirmed the anti-oxidation effect of melatonin in yak embryos that significantly improved the quantity and quality of blastocysts in the in vitro production of embryos in yaks.

Abstract
The objective of the study was to establish correlation of seminal and serum IGF-1 with seminal attributes, estimate antioxidant potential of IGF-1 by 2, 2-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) assays and to study the effect of IGF-1 supplementation on semen cryopreservation. For this study, buffalo bulls were divided into sub-fertile (n = 2) and normal (n = 5) on the basis of sperm mass motility and individual motility. The serum IGF-1 concentration of normal bulls was greater than in sub-fertile bulls, but there was no difference in the seminal IGF-1 concentration among the groups. The values from correlation analyses indicated that serum IGF-1 concentration is positively correlated with semen mass motility and sperm concentration. In the second experiment, IGF-1 did not have antioxidant activities when assessed with DPPH and FRAP assays. In the third experiment, the ejaculates of normal and sub-fertile bulls were cryopreserved using semen extender in which there was IGF-1 supplementation at 0 (control), 50, 100, 150, 200, 250, 350 and 450 ng/mL of extender. Supplementation of IGF-1 at 250 ng/ml resulted in improved sperm motility, longevity and membrane intactness as compared to control after cryopreservation of semen from normal buffalo bulls, but not sub-fertile bulls. In summary, serum IGF-1 concentration was correlated with sperm mass motility and concentration in buffalo bulls and supplementation of IGF-1 protected sperm during the cryopreservation process but effects were not due to direct antioxidant activity.

Abstract
Male patients suffering from oligoasthenoteratozoospermia typically failed to
achieve pregnancy, even with assisted reproductive technologies. Growth hormone
and insulin-like growth factor 1 have been shown to regulate sperm quality
parameters; therefore, the insulin-like growth factor 1 supplement could improve
sperm parameters. Here, we determine the effect insulin-like growth factor 1 has
on sperm parameters in a patient suffering from oligoasthenoteratozoospermia. A
47-year-old male was administered once a day 1.5 IU of insulin-like growth
factor 1 by intradermal injection for 2 months. Seminogram analysis was
performed before and after. Treatment with insulin-like growth factor 1 resulted
in a 15.5-fold improvement in sperm concentration (1.1 × 106 vs 18.3
× 106 per mL), 71.4% change in volume (0.7 vs 1.2 mL), increased
progressive motility (2% vs 43%), and the total volume of sperm with progressive
motility (0% vs 23.6%). Here, we show that administering a daily dose of
insulin-like growth factor 1 can improve sperm quality parameters.

Abstract
Insulin-like growth factor-1 (IGF-1) is an important regulator of cardiomyocyte homeostasis and cardiac structure, and the prosurvival and antiapoptotic effects of IGF-1 have been investigated. However, the effect of microRNA-320 (miR-320) in ischemia and reperfusion (I/R) by targeting IGF-1 is rarely discussed. We investigated the role of miR-320 in I/R injury. A total of 192 healthy female Wistar rats were divided into eight groups (n = 24). Rat heart I/R model was established. Hemodynamics, infarct size weight (ISW), heart function, and rat cardiomyocyte apoptosis were measured. Hypoxia-reoxygenation (H/R) in rat cardiomyocyte was used to simulate the I/R process. The mRNA levels of miR-320 and IGF-1, and proteins levels of IGF-1, IGF-1R, p-IGF-1R, p-ASK1, p-JNK, p-p38, Bcl-2, Bax and Caspase-3 were measured. In vivo inhibition of miR-320 expression significantly increased IGF-1 and IGF-1R mRNA levels, elevated the absolute values of SBP, DBP, MAP, ± dp/dtmax, LVEF and LVFS, decreased ISW, LVESD and LVEDd and the number of TUNEL positive cells, lowered the levels of p-ASK1, p-JNK, p-p38, Bax and Caspase-3 and increased expression of Bcl-2 compared to the I/R + NC group. Compared to H/R + NC group in vitro, miR-320 inhibition increased IGF-1 mRNA levels, inhibited cardiomyocyte apoptosis, down-regulated p-ASK, p-JNK, p-p38, Bax and Caspase-3 levels, and up-regulated Bcl-2 level. MiR-320 inhibition target elevated IGF-1 mRNA and protein levels, suppress early cardiomyocyte apoptosis of I/R, and inhibited ASK1-JNK/p38 pathway, which provides a new target for clinical study of I/R injury.

Abstract
The present study was aimed at evaluating the seminal plasma proteins and sperm parameters of Curraleiro Pé-Duro bulls. Semen was collected from 10 bulls by electroejaculation, and sperm parameters were evaluated in fresh and frozen-thawed semen. Seminal plasma proteins were analyzed by 2-D SDS-PAGE and mass spectrophotometry. Tools in computational biology were used to generate bioinformatic knowledge and evaluate gene ontology, protein-protein interactions, phylogenetic trees and multiple sequence alignments. Sperm motility in fresh and frozen-thawed semen was 78.8±1.8% and 21.2±1.6%, respectively. Pearson's correlations were evaluated (p<0.05). Sperm motility and vigor in fresh semen were correlated with clusterin, TIMP2 and cathepsin S (r=0.64-0.71) and sperm defects were related to inhibitor of carbonic anhydrase and BSP 5 (r=0.78-0.80). Clusterin, BSP 5, alpha-enolase, creatine kinase M-type, glyceraldehyde-3-phosphate dehydrogenase, BSP 3, albumin, and 5'-nucleotidase and legumain were correlated with acrosome intact live sperm (r=0.80-0.64). Associations were detected between sperm vigor and spermadhesin 1 (r=-0.89), and between sperm defects in fresh semen and spermadhesin 1 and clusterin (r=-0.81). Sperm motility in frozen-thawed semen was associated with BSP 1, spermadhesin 1, clusterin and spermadhesin Z13 (r=0.64-0.85). The percent of motile sperm after freeze-thawing was negatively correlated (r=-0.64) with the amount of spermadhesin 1 in the seminal plasma. Based on in silico analysis, TIMP2 interacted with BSP1, BSP3, BSP5 and metalloproteinases. Molecular functions of proteins associated with sperm parameters were binding, catalytic activity and enzymatic regulation. Amino acid sequences of spermadhesin 1 and BSP 1 from Bos taurus, and other domestic species were similar. Phylogenetic tree analysis demonstrated that clusterin from Bos taurus was related to Ovis aries and domains of clusterin, spermadhesin 1, BSP 1 and inhibitor of carbonic anhydrase were conserved as well. In summary, specific seminal proteins are associated with sperm parameters of locally-adapted bulls. Use of the endangered mammalian as a model may assist in understanding aspects of evolutionary adaptations and could improve assisted reproductive biotechnologies.

Abstract
The objective of this study was to investigate whether developmental competence of mature vitrified-warmed yak (Bos grunniens) oocytes can be enhanced by supplemented insulin-like growth factor I (IGF-1) during in vitro maturation (IVM), and its relationship with the expression of cold-inducible RNA-binding protein (CIRP). In experiment 1, immature yak oocytes were divided into four groups, and IVM supplemented with 0, 50, 100 and 200 ng/mL IGF-1 was evaluated; the mRNA and protein expression levels of CIRP in mature oocytes in the four groups were evaluated using quantitative real-time PCR and western blotting analyses. In experiment 2, the mature yak oocytes in the four groups were cryopreserved using the Cryotop (CT) method, followed by chemical activation and in vitro culture for two days and eight days to determine cleavage, blastocyst rates, and total cell number in the blastocysts. Mature yak oocytes without vitrification served as a control group. The outcomes were as following: (1) the expression of CIRP in the matured oocytes was up-regulated in the IGF-1 groups and was highest expression was observed in the 100 ng/mL IGF-1 treatment group. (2) In the vitrified-warmed groups, the rates of cleavage and blastocyst were also highest in the 100 ng/mL IGF-1 treatment group (81.04 ± 1.06%% and 32.16 ± 1.01%), which were close to the rates observed in groups without vitrification (83.25 ± 0.85% and 32.54 ± 0.34%). The rates of cleavage and blastocyst in the other vitrified-warmed groups were 70.92 ± 1.32% and 27.33 ± 1.31% (0 ng/mL); 72.73 ± 0.74% and 29.41 ± 0.84% (50 ng/mL); 72.43 ± 0.61% and 27.61 ± 0.59% (200 ng/mL), respectively. There was no significant difference in the total cell number per blastocysts between the vitrified-warmed groups and group without vitrification. Thus, we conclude that the enhancement in developmental competence of mature yak vitrified-warmed oocytes after the addition of IGF-1 during IVM might result from the regulation of CIRP expression in mature yak oocytes prior to vitrification.
