Liu Z, Chen Y, Huang M, Du Y, Xu G, Liu Z, Zhang M, Presicce GA, Xing X, Du F. Effects of hormone sources on developmental competence of oocytes by ovum pickup in Japanese black cattle. Anim Reprod Sci 2024; 267:107533. [PMID: 38879972 DOI: 10.1016/j.anireprosci.2024.107533] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2024] [Revised: 06/08/2024] [Accepted: 06/11/2024] [Indexed: 06/18/2024]
Abstract
Japanese Black (Wagyu) cattle donors were primed with different protocols and sources of follicle-stimulating hormone (FSH) for successive ovum pickup (OPU) and embryo development after in vitro fertilization (IVF). Following OPU, retrieved cumulus oocyte complexes (COCs) were subjected to IVF, and resulting blastocysts were transferred into recipients to evaluate implantation capability. Experiment 1: The best blastocyst development (45.3 %) and embryo yields (5.0/donor/OPU) were found with oocytes retrieved from donors treated with FSH (STIMUFOL®, Belgium) at a dosage of 150 IU per donor, compared to two others commercial FSH sources. Experiment 2: There were no differences in embryo development or yield with STIMUFOL FSH (total FSH 150 IU/donor) at a priming duration of either 60-h (Regime 1, six FSH injections) or 36-h (Regime 2, four FSH injections). Experiment 3: Compacted COCs required 22-26-h maturation in vitro (IVM) before IVF for optimal blastocyst development (36.1-41.1 %); however, short (18-h) and prolonged (30-h) IVM duration resulted in lower embryonic development. In contrast, expanded COCs resulted in inferior blastocyst development compared to compacted COCs. Immunofluorescence microscopy revealed that the ratio of 89.8 % cumulus compacted COCs were at the germinal vesicle (pachytene) phase while 98.9 % cumulus expanded COCs went through spontaneous meiosis from meiotic metaphase I, anaphase I, telophase I to metaphase II upon OPU retrieval (P<0.05). Pregnancy rates were not different among three FSH sources or different FSH treatments as long as embryos reached the blastocyst stage. Our study found that different sources of FSH used for Wagyu donor priming prior to OPU resulted in differential embryo development potentials, but those embryos that reached out to blastocysts had a competent implantation ability.

Cellular atlas of the human ovary using morphologically guided spatial transcriptomics and single-cell sequencing. SCIENCE ADVANCES 2024; 10:eadm7506.

Abstract
The reproductive and endocrine functions of the ovary involve spatially defined interactions among specialized cell populations. Despite the ovary's importance in fertility and endocrine health, functional attributes of ovarian cells are largely uncharacterized. Here, we profiled >18,000 genes in 257 regions from the ovaries of two premenopausal donors to examine the functional units in the ovary. We also generated single-cell RNA sequencing data for 21,198 cells from three additional donors and identified four major cell types and four immune cell subtypes. Custom selection of sampling areas revealed distinct gene activities for oocytes, theca, and granulosa cells. These data contributed panels of oocyte-, theca-, and granulosa-specific genes, thus expanding the knowledge of molecular programs driving follicle development. Serial samples around oocytes and across the cortex and medulla uncovered previously unappreciated variation of hormone and extracellular matrix remodeling activities. This combined spatial and single-cell atlas serves as a resource for future studies of rare cells and pathological states in the ovary.

Zareifard A, Beaudry F, Ndiaye K. Janus Kinase 3 phosphorylation and the JAK/STAT pathway are positively modulated by follicle-stimulating hormone (FSH) in bovine granulosa cells. BMC Mol Cell Biol 2023; 24:21. [PMID: 37337185 DOI: 10.1186/s12860-023-00482-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2022] [Accepted: 05/09/2023] [Indexed: 06/21/2023] Open
Abstract
Janus kinase 3 (JAK3) is a member of the JAK family of tyrosine kinase proteins involved in cytokine receptor-mediated intracellular signal transduction through the JAK/STAT signaling pathway. JAK3 was previously shown as differentially expressed in granulosa cells (GC) of bovine pre-ovulatory follicles suggesting that JAK3 could modulate GC function and activation/inhibition of downstream targets. We used JANEX-1, a JAK3 inhibitor, and FSH treatments and analyzed proliferation markers, steroidogenic enzymes and phosphorylation of target proteins including STAT3, CDKN1B/p27Kip1 and MAPK8IP3/JIP3. Cultured GC were treated with or without FSH in the presence or not of JANEX-1. Expression of steroidogenic enzyme CYP11A1, but not CYP19A1, was upregulated in GC treated with FSH and both were significantly decreased when JAK3 was inhibited. Proliferation markers CCND2 and PCNA were reduced in JANEX-1-treated GC and upregulated by FSH. Western blots analyses showed that JANEX-1 treatment reduced pSTAT3 amounts while JAK3 overexpression increased pSTAT3. Similarly, FSH treatment increased pSTAT3 even in JANEX-1-treated GC. UHPLC-MS/MS analyses revealed phosphorylation of specific amino acid residues within JAK3 as well as CDKN1B and MAPK8IP3 suggesting possible activation or inhibition post-FSH or JANEX-1 treatments. We show that FSH activates JAK3 in GC, which could phosphorylate target proteins and likely modulate other signaling pathways involving CDKN1B and MAPK8IP3, therefore controlling GC proliferation and steroidogenic activity.

The Emerging Role of Epigenetics in Metabolism and Endocrinology. BIOLOGY 2023; 12:biology12020256.

Abstract
Each cell in a multicellular organism has its own phenotype despite sharing the same genome. Epigenetics is a somatic, heritable pattern of gene expression or cellular phenotype mediated by structural changes in chromatin that occur without altering the DNA sequence. Epigenetic modification is an important factor in determining the level and timing of gene expression in response to endogenous and exogenous stimuli. There is also growing evidence concerning the interaction between epigenetics and metabolism. Accordingly, several enzymes that consume vital metabolites as substrates or cofactors are used during the catalysis of epigenetic modification. Therefore, altered metabolism might lead to diseases and pathogenesis, including endocrine disorders and cancer. In addition, it has been demonstrated that epigenetic modification influences the endocrine system and immune response-related pathways. In this regard, epigenetic modification may impact the levels of hormones that are important in regulating growth, development, reproduction, energy balance, and metabolism. Altering the function of the endocrine system has negative health consequences. Furthermore, endocrine disruptors (EDC) have a significant impact on the endocrine system, causing the abnormal functioning of hormones and their receptors, resulting in various diseases and disorders. Overall, this review focuses on the impact of epigenetics on the endocrine system and its interaction with metabolism.

Follicle-stimulating hormone mediates the consumption of serum-derived glycogen by bovine cumulus-oocyte complexes during in vitro maturation. Vet World 2021; 14:2512-2517. [PMID: 34840472 PMCID: PMC8613776 DOI: 10.14202/vetworld.2021.2512-2517] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2021] [Accepted: 08/23/2021] [Indexed: 11/19/2022] Open
Abstract
Background and Aim: Oocyte in vitro maturation (IVM) is an appealing approach for several assisted reproductive technologies and dissecting oocyte maturation. Nonetheless, IVM leads to lower developmental competence and usually relies on undefined, serum-containing media. Therefore, biochemical profiling aimed to explore fluctuations in IVM media content during the acquisition of oocyte developmental competence. Materials and Methods: Bovine cumulus-oocyte complexes (COCs) underwent IVM in TCM199 medium with Earle’s salts, supplemented with 2.0 mM L-glutamine, 10% fetal bovine serum, antibiotics, and 0.05 IU/mL porcine follicle-stimulating hormone (FSH+) or vehicle control (CTL) medium for 22 h. Results: FSH withdrawal (CTL) diminished several processes associated with the acquisition of oocyte developmental competence, such as reduced cumulus cell expansion, diminished estradiol synthesis (FSH+: 116.0±0.0 pg/mL vs. CTL: 97.6±18.0 pg/mL), and lower oocyte nuclear maturation rate (FSH+: 96.47% vs. CTL: 88.76%). Fresh media formulations (i.e., TCM199 with FSH or vehicle) were indistinguishable under biochemical profiling threshold conditions. Biochemical profiling showed similar total protein and lipid concentrations between groups. Further, total sugar concentrations diminished from fresh media to their post-IVM counterparts, albeit in an FSH-independent manner. Glycogen concentrations remained unaltered after IVM within CTL media, albeit were substantially lower after IVM under FSH+ conditions. Conclusion: FSH mediates the consumption of serum-derived glycogen by bovine COCs during IVM and implies that serum-free media should contain increased glucose concentrations to facilitate the acquisition of oocyte developmental competence.
