Yuan X, Chen N, Feng Y, Li N, Pan X, Tian Y, Wang J, Jiang Y, He D, Li J, Gao F. Single-cell multi-omics profiling reveals key regulatory mechanisms that poise germinal vesicle oocytes for maturation in pigs. Cell Mol Life Sci 2023; 80:222. [PMID: 37480402 PMCID: PMC11072314 DOI: 10.1007/s00018-023-04873-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2023] [Revised: 07/11/2023] [Accepted: 07/12/2023] [Indexed: 07/24/2023]
Abstract
The molecular mechanisms controlling the transition from meiotic arrest to meiotic resumption in mammalian oocytes have not been fully elucidated. Single-cell omics technology provides a new opportunity to decipher the early molecular events of oocyte growth in mammals. Here we focused on analyzing oocytes that were collected from antral follicles in different diameters of porcine pubertal ovaries, and used single-cell M&T-seq technology to analyze the nuclear DNA methylome and cytoplasmic transcriptome in parallel for 62 oocytes. 10× Genomics single-cell transcriptomic analyses were also performed to explore the bi-directional cell-cell communications within antral follicles. A new pipeline, methyConcerto, was developed to specifically and comprehensively characterize the methylation profile and allele-specific methylation events for a single-cell methylome. We characterized the gene expressions and DNA methylations of individual oocyte in porcine antral follicle, and both active and inactive gene's bodies displayed high methylation levels, thereby enabled defining two distinct types of oocytes. Although the methylation levels of Type II were higher than that of Type I, Type II contained nearly two times more of cytoplasmic transcripts than Type I. Moreover, the imprinting methylation patterns of Type II were more dramatically divergent than Type I, and the gene expressions and DNA methylations of Type II were more similar with that of MII oocytes. The crosstalk between granulosa cells and Type II oocytes was active, and these observations revealed that Type II was more poised for maturation. We further confirmed Insulin Receptor Substrate-1 in insulin signaling pathway is a key regulator on maturation by in vitro maturation experiments. Our study provides new insights into the regulatory mechanisms between meiotic arrest and meiotic resumption in mammalian oocytes. We also provide a new analytical package for future single-cell methylomics study.

Effects of the addition of insulin-transferrin-selenium (ITS) and/or metformin to the in vitro maturation of porcine oocytes on cytoplasmic maturation and embryo development. Reprod Fertil Dev 2023; 35:363-374. [PMID: 36780707 DOI: 10.1071/rd22254] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/07/2022] [Accepted: 01/21/2023] [Indexed: 02/15/2023] Open
Abstract
CONTEXT One of the main problems of porcine in vitro maturation (IVM) is incomplete cytoplasmatic maturation. Nuclear and cytoplasmic maturation will determine the future success of fertilisation and embryo development. Insulin-transferrin-selenium (ITS) has insulin-like and antioxidant effects, and metformin (M) is an insulin-sensitiser and antioxidant drug. AIMS To assess the effects of adding ITS and/or M in porcine IVM media on cytoplasmic maturation and early embryo development. METHODS Cumulus -oocyte complexes (COC) were IVM with M (10-4 M), ITS (0.1% v/v), M+ITS or no adding (Control). KEY RESULTS ITS increased glucose consumption compared to Control and M (P <0.01), and M+ITS did not differ from ITS or Control. Redox balance: M, ITS and M+ITS increased glutathione (P <0.01) and decreased lipid peroxidation (P <0.005). The viability of cumulus cells by flow cytometry increased with M (P <0.005) and decreased with ITS (P <0.001); M+ITS did not differ from Control. After IVF, M increased penetration and decreased male pronucleus (P <0.05). Embryo development: cleavage increased with M (P <0.05), and blastocysts increased with ITS and M+ITS (P <0.05). The number of blastocyst cells increased with ITS (P <0.05). CONCLUSIONS Adding ITS and M+ITS to porcine IVM media benefits embryo development to blastocysts, but ITS alone has better effects than M+ITS. IMPLICATIONS ITS is an excellent tool to improve IVM and embryo development after IVF in pigs.

Abstract
In females, the establishment of the primordial follicle pool is accompanied by a remarkable programmed oocyte loss for unclear reasons. In this study, the role of autophagy was investigated to serve as a protective mechanism for oocyte survival during chicken folliculogenesis. Inhibition of autophagy by 3-methyladenine (3-MA) led to a remarkable delay in germ cell cyst breakdown that resulted in fewer primordial follicles and retarded sequent follicular development either in vivo or in the ovarian organ culture. Furthermore, the glycolysis level was downregulated in ovaries treated with 3-MA, while Recilisib (a specific activator of Akt) reversed this inhibiting effect of 3-MA on primordial folliculogenesis. Collectively, these data indicate that autophagy functions to maintain germ cell cyst breakdown and primordial follicle assembly by regulating ovarian glycolysis involving Akt signaling in the ovaries of newly-hatched chickens.

Abstract
Successful reproduction is very important for individuals and for society. Currently, the human health span and lifespan are the object of intense and productive investigation with great achievements, compared to the last century. However, reproduction span does not progress concomitantly with lifespan. Reproductive organs age, decreasing the levels of sexual hormones, which are protectors of health through their action on several organs of the body. Thus, this is the starting point of the organismal decay and infertility. This starting point is easily detected in women. In men, it goes under the surface, undetected, but it goes, nevertheless. Regarding fertility, aging alters the hormonal equilibrium, decreases the potential of reproductive organs, diminishes the quality of the gametes and worsen the reproductive outcomes. All these events happen at a different pace and affecting different organs in women and men. The question is what molecular pathways are involved in reproductive aging and if there is a possible halting or even reversion of the aging events. Answers to all these points will be explained in the present review.

Abstract
PURPOSE To enhance the in vitro growth of porcine oocytes, we studied the effect of mural granulosa cells (MGCs) on the viability of oocytes attached to granulosa cells (oocyte-granulosa cell complexes, OGCs) that were obtained from early antral follicles. METHODS AND RESULTS When OGCs were cultured with MGCs for 12 days, there were significant improvement (P < 0.05) in the robustness of gap junctional communication between the oocyte and the granulosa cells (82% vs. 59%), the survival rate of oocytes (57% vs. 39%), and the diameter of survived oocytes (118 μm vs. 112 μm). The rate of oocyte release of OGCs cultured with MGCs on the 12th day (1.9%) was significantly lower than that of OGCs cultured without MGCs (26%). Complete meiotic arrest was maintained in the group with MGCs (100%), while partial resumption of spontaneous meiosis was noticed in the absence of MGCs (10-19%). Furthermore, the presence of MGCs increased the oocyte maturation rate after maturation culture in both 12- and 14-day culture groups (P < 0.05, 85-88%) compared to OGCs cultured without MGCs (48-60%). MGCs also significantly improved the blastocyst formation rate (day 7) after ICSI (P < 0.05). CONCLUSIONS The data of this study thus shows that the presence of MGCs during in vitro oocyte growth plays a crucial role in supporting the developmental competence of growing porcine oocytes attached to the granulosa cells via enhancement of their viability.

The subtle balance of insulin and thyroxine on survival and development of in vitro cultured caprine preantral follicles enclosed in ovarian tissue. Theriogenology 2020; 147:10-17.

Abstract
Numerous studies have reported the importance of thyroid hormones on the development of later preantral and antral follicles, but their interactions with other hormones and effects in regulating early preantral follicle growth remain unclear. Here we investigated the in vitro effects of thyroxine combined with insulin on caprine preantral follicle survival and development. Sliced ovarian tissues were cultured for 1 or 7 days using 10 ng/mL (low) or 10 μg/mL (high) insulin in the presence of thyroxine at 0, 0.5, 1 or 2 μg/mL. Post-culture, we evaluated the follicular survival and development, assessed the expression of apoptotic-related genes (Bcl2/Bax) and receptors of insulin and thyroid hormones, and quantified the estradiol and reactive oxygen species (ROS) production levels. Follicular survival in low-insulin culture conditions was enhanced by the presence of 0.5 μg/mL thyroxine (P < 0.05) as compared to the thyroxine-free medium but remained similar to non-cultured control in the presence of 2 μg/mL (P > 0.05). Significantly higher ROS production was measured from Day 1 to Day 7 in low-insulin culture media containing 0.5 or 2 μg/mL thyroxine (P < 0.05). When compared to high insulin level, the presence of thyroxine in low insulin culture conditions yielded higher stromal cell density (P < 0.05), increased estradiol production on Day 1, and higher Bcl2/Bax ratio on Day 7. Cultures with high levels of both insulin and thyroxine led to follicles and oocytes with larger diameters (P < 0.05). The RNA transcript levels of insulin and thyroid receptors were reduced in the presence of high insulin cultures when compared to controls (non-cultured). In conclusion, the combination of low concentrations of insulin and thyroxine better maintained follicle survival, while high levels ensured better follicular development.

Abstract
Granulosa cells (GCs) contribute to oocyte development. The present study addressed the effect of cryopreservation on the ability of GCs to support oocyte development. GCs were collected from antral follicles. Oocyte granulosa cell complexes (OGCs) derived from early antral follicles were cultured with additional fresh-GCs or frozen-thawed-GCs for 14 days, and the developmental ability and characteristics of the oocytes grown in vitro were examined. Furthermore, fresh- or frozen-thawed-GCs were cultured for two days, and the effects of cryopreservation on the characteristics of GCs were examined. The developmental ability of blastocysts and the acetylation levels of H4K12 in oocytes grown in vitro did not significantly differ among the three culture conditions: OGCs cultured with additional fresh-GCs, frozen-thawed-GCs, or without additional GCs. Although both fresh- and frozen-thawed-GCs exhibited increased ATP content compared with that in oocytes developed without additional GCs, only fresh-GCs showed significantly increased lipid content in oocytes grown in vitro. ATP content, reactive oxygen content, mitochondrial membrane potential, and mitochondrial DNA copy number were greater in cultured frozen-thawed-GCs compared with fresh-GCs. In contrast, lipid content of cultured frozen-thawed-GCs was lower than that of fresh-GCs. Both fresh- and frozen-GCs support oocyte growth, but cryopreservation changes the properties of GCs in a manner that affects the energy status of oocytes grown in vitro.

Abstract
Retinol binding protein 4 (RBP4), mainly secreted by the liver and adipocytes, is a transporter of vitamin A. RBP4 has been shown to be involved in several pathophysiological processes, such as obesity, insulin resistance, and cardiovascular risk. Reports have indicated the high expression levels of RBP4 in cystic follicles. However, the role of RBP4 in mammalian follicular granulosa cells (GCs) remains largely unknown. To illustrate the molecular pathways associated with the effects of RBP4 on GCs, we used high-throughput sequencing to detect differential gene expression in GCs overexpressing RBP4. A total of 113 differentially expressed genes (DEGs) were identified in RBP4-overexpressing GCs, and they included 71 upregulated and 42 downregulated genes. The differential expressions of the top 10 DEGs were further confirmed by real-time quantitative polymerase chain reaction. Pathway analysis indicated that the DEGs are mostly involved in oxidative phosphorylation, Parkinson’s disease, non-alcoholic fatty liver disease, Huntington’s disease, cardiac muscle contraction, Alzheimer’s disease, fatty acid biosynthesis, AMP-activated protein kinase signaling pathway, and insulin signaling pathway. Genes in these pathways should be useful for future studies on GCs. Altogether, the results of our study establish a framework for understanding the potential functions of RBP4 in porcine GCs.

Abstract
PURPOSE This study aimed to examine the relationship between granulosa cells (GCs), number of follicles, and the ability of follicular fluid to support in vitro growth of oocytes. METHODS The culture medium was supplemented with follicular fluid (FF) collected from GC-rich ovaries and GC-poor ovaries, and its effect on in vitro growth and quality of oocytes derived from early antral follicles (EAFs) was assessed. RESULTS GC-rich FF treatment enhanced oocyte growth and augmented changes in the chromatin configuration and lipid content of oocytes when compared to oocytes treated with GC-poor FF. Moreover, oocytes treated with GC-rich FF had a higher ability to progress to the blastocyst stage, than oocytes derived from large antral follicles (3-5 mm in diameter). In addition, supplementation of the culture medium with either GC-rich or GC-poor FF enhanced histone acetylation in oocytes grown in vitro. CONCLUSION GC-rich FF contains key factors that support in vitro oocyte growth; hence, oocytes grown in GC-rich FF medium had high developmental competence, which was comparative to the oocytes grown in vivo.

To determine the optimum culture duration for porcine growing oocytes (GOs) to attain maturation competence, we examined the meiotic competence, chromatin configuration, and fertilization ability of porcine oocytes
obtained from early antral follicles and cultured for 10–16 days. The survival rate of oocytes after 10 days of culture (62.8%) was similar to that of oocytes after 12 days of culture (55%) and significantly higher than
that of oocytes cultured for 14 and 16 days (52.9 and 24.3%, respectively). No significant difference was observed in the diameter of ooplasm from oocytes cultured for different durations (117.4–118.3 μm). The maturation
rates of surviving oocytes after 10 and 16 days of culture (38.3 and 22.7%, respectively) were significantly lower than those of oocytes cultured for 12 and 14 days, and their in vivo counterparts
(52.8–62.4%). The number of oocytes with surrounded-nucleolus chromatin was significantly lower in the 10-day culture group (78.4%) as compared with 14-day culture and in vivo counterpart groups (93.6
and 95.1%, respectively). After in vitro maturation and intracytoplasmic sperm injection, no significant difference was observed in the rate of fertilization among oocytes cultured for 12 and 14 days,
and their in vivo counterparts (40.5–47.2%). Thus, porcine GOs required at least 12 days to acquire meiotic and fertilization competence, and the culture duration to maximize the number of mature oocytes
ranged from 12 to 14 days.

Abstract
Age-associated decline in oocyte quality is common in mammals. Oocytes take a long time to reach their full-grown size in large animals, and maternal physical conditions profoundly affect follicle development. Aging affects the oocyte itself as well as the surrounding environment, such as granulosa cells and follicular fluid. This review discusses age-associated changes that occur in granulosa cells and follicular fluid in cows and suggests that age-associated decline in granulosa cells and follicular fluid hampers proper oocyte development.
