Abstract
PURPOSE To depict the lncRNA expression during human oocyte maturation and explore the lncRNAs leading to recurrent oocyte maturation arrest. METHODS LncRNA sequencing was performed on pooled RNA from 20 oocytes of each group (recurrent oocyte maturation arrest (ROMA), of germinal vesicle (GV), metaphase I (MI), or metaphase II (MII) stages. Bioinformatics software was deployed to compare the lncRNA differential expression between the normal and ROMA oocytes. The co-expression of lncRNA/mRNA was illustrated with the Cytoscape software. The pooled RNA from every 10 oocytes of each group (ROMA, GV, MI, MII) was extracted for further qPCR validation. RESULTS There were 17 downregulated and 3 upregulated lncRNAs in the ROMA oocyte. Among them, co-expression analysis indicated that NEAT1 and NORAD were both downregulated. Basing on the KEGG enrichment analysis, PRCKA and JAK3 might be the target genes in the PI3K-Akt pathway and modulated by NEAT1 and NORAD. As validated by qPCR, the expressional levels of lncRNA candidates (NEAT1 and NORAD) and their target genes (PRKCA and JAK3) were confirmed to be extremely lower in the ROMA oocyte than in the normal oocyte. CONCLUSION By targeting the PI3K-Akt pathway genes PRKCA and JAK3, the abnormal expression of NEAT1 and NORAD is suggested to impede oocyte maturation and impair oocyte genome integrity.

Dong YQ, Chen CQ, Huang YQ, Liu D, Zhang XQ, Liu FH. In vitro maturation of human oocytes maintaining good development potential for rescue intracytoplasmic sperm injection with fresh sperm. World J Clin Cases 2022; 10:2166-2173. [PMID: 35321156 PMCID: PMC8895176 DOI: 10.12998/wjcc.v10.i7.2166] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/27/2021] [Revised: 12/24/2021] [Accepted: 01/20/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND The outcomes of the use of commercial in vitro maturation (IVM) medium to culture immature oocytes obtained from conventional ovulation induction, followed by rescue intracytoplasmic sperm injection (RICSI), are not ideal. It is thus difficult to widely adopt this approach in clinical practice. Therefore, it is necessary to explore methods for improving the clinical outcome of IVM.
AIM To study the effect of sperm on the developmental potential of in vitro-matured oocytes in conventional culture.
METHODS This was a retrospective study of patients whose immature oocytes were harvested from conventional oocyte stimulation cycles and underwent ICSI at our hospital between June 2018 and August 2020. RICSI was performed using sperm collected on the day of oocyte harvest (old) and sperm collected on the day of RICSI (fresh) and oocytes matured in vitro after 24 h of culture in conventional medium. The rates of in vitro oocyte maturation, normal fertilization, normal cleavage, day-3 top-quality embryos, and useful blastocyst formation were compared between the two groups.
RESULTS In total, 102 germinal vesicle (GV)-stage immature oocytes were cultured in the old sperm group. In the fresh sperm group, 122 GV-stage immature oocytes were collected and cultured in vitro for 24 h. There were no significant differences in the general conditions of males and females between the two groups (P > 0.05). The oocyte maturation, normal fertilization, and normal cleavage rates of the old and fresh groups were 51.0% vs 55.7%, 61.5% vs 64.7%, and 93.8% vs 93.2%, respectively. None of the rates differed significantly (P > 0.05) between the two groups. However, the day-3 top-quality embryo and useful blastocyst rates of the old and fresh sperm groups were 16.6% vs 63.4%; 6.67% vs 34.6%, respectively. The day-3 top-quality embryos and useful blastocyst rates of the old sperm group were significantly lower than those of the fresh group (P < 0.05).
CONCLUSION In vitro maturation with conventional culture medium combined with the use of fresh sperm collected on the day of RICSI is an easy-to-implement strategy for patients whose oocytes are completely or mostly immature.

Novel mutations in NLRP5 and PATL2 cause female infertility characterized by primarily oocyte maturation abnormality and consequent early embryonic arrest. J Assist Reprod Genet 2022; 39:711-718. [PMID: 35091966 PMCID: PMC8995404 DOI: 10.1007/s10815-022-02412-4] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2021] [Accepted: 01/24/2022] [Indexed: 12/28/2022] Open
Abstract
PURPOSE This study aims to identify the genetic causes of 12 women with primary infertility characterized by primarily oocyte maturation abnormality and consequent early embryonic arrest. METHODS Genomic DNA was isolated from peripheral blood samples. Whole-exome sequencing was performed on the probands, and the identified variants were confirmed by Sanger sequencing. The pathogenicity of the identified variants on the protein was accessed in silico. And we used qRT-PCR to detect the possible effects of the novel mutation on the mRNA level of NLRP5. RESULTS A novel homozygous frameshift variant (p.V429Efs*30) in NLRP5 and compound heterozygous variants with a novel frameshift variant (p.A297Efs*20) and a recurrent variant (c. 223-14_223-2delCCCTCCTGTTCCA) in PATL2 were identified in two unrelated affected individuals. qRT-PCR showed an obvious decrease of the mutant NLRP5 mRNA. In addition, the truncated proteins of NLRP5 and PATL2 were predicted to be non-functional due to the deletion of the most or the whole region of the critical functional domain(s) respectively. CONCLUSIONS This study identified novel mutations in NLRP5 and PATL2, further expanding the mutational and phenotypic spectrum of both genes. This is the first report of the NLRP5 mutations that associates with oocyte maturation abnormality in humans.

Front Endocrinol (Lausanne) 2022; 13:1016563. [PMID: 36440233 PMCID: PMC9684610 DOI: 10.3389/fendo.2022.1016563] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/11/2022] [Accepted: 10/28/2022] [Indexed: 11/11/2022] Open
Abstract
BACKGROUND oocyte maturation arrest (OMA) is currently one of the major causes of in vitro fertilization (IVF) failure, and several gene mutations were found to be associated with OMA. The purpose of this study was to identify the oocyte phenotype, genetic diagnosis, and clinical outcomes of patients with OMA and explore their possible interrelationships, thus providing a more individualized and efficient treatment strategy guidance accordingly. METHODS A retrospective study was conducted, involving 28 infertile women with OMA in the Reproductive Medicine Center of Tongji Hospital from 2018 to 2021. Whole-exome sequencing was performed for the detection of gene mutations. Patients were classified into three groups based on their oocyte phenotype, and for each group, the immature oocytes were cultured in vitro and mature oocytes were fertilized to evaluate both the maturation capacity and developmental potential. The clinical outcomes of OMA patients with different gene mutations or from different groups were further analyzed and compared. RESULTS Twenty-eight women with OMA were evaluated in this study. According to the stage of OMA, 14 (50.0%) women were classified as OMA Type-1 (GV arrest), 5 (17.9%) were OMA Type-2 (MI arrest), and 9 (32.1%) were OMA Type-3 (with both GV and MI arrest). Immature oocytes from OMA patients exhibited significantly lower maturation rates even after IVM, compared to those in general patients. Seven patients (25.0%) were detected to have deleterious variations in two genes (PATL2 and TUBB8), known to be associated with the OMA phenotype. Patients with identified mutations were found to have little opportunity to obtain offspring with their own oocytes. Among the patients without mutations identified, those classified as OMA Type-1 or Type-3 still had a chance to obtain offspring through IVF or natural pregnancy, while all patients in the Type-2 group failed to obtain live birth. CONCLUSIONS Three different phenotypes were observed in patients with OMA. The clinical outcomes of patients were associated with the presence of gene mutations and the classification of oocyte phenotype, thus a reasonable triage system was proposed to optimize the allocation of health care resources and maximize patient benefit.

Novel Mutations in CDC20 Are Associated with Female Infertility Due to Oocyte Maturation Abnormality and Early Embryonic Arrest. Reprod Sci 2021; 28:1930-1938. [PMID: 33683667 DOI: 10.1007/s43032-021-00524-3] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2021] [Accepted: 03/01/2021] [Indexed: 10/22/2022]
Abstract
The cell division cycle 20 (CDC20) protein is a co-activator of anaphase-promoting complex/cyclosome (APC/C), required for mitotic exit and also meiotic exit, containing seven WD40 repeats in the C-terminus responsible for protein-protein interactions. Recently, a previous study has shown that biallelic mutations in CDC20 are causative for female infertility with abnormalities in oocyte maturation and embryonic development. This study is to further identify new mutations of CDC20 and the prevalence of variants in our cohort. A cohort of 50 primary infertile females with oocyte maturation abnormality and early embryonic arrest were recruited. Genomic DNA was isolated from peripheral blood samples. Mutation screening of all the coding regions of CDC20 was performed by Sanger sequencing. The pathogenicity of the identified variants on the CDC20 protein was accessed in silico. Two CDC20 variants, a nonsense mutation p.R262* and a missense mutation p.A211T, identified in one female of 50 unrelated affected individuals, accounting for a relative small proportion of this cohort (2%). In silico analysis revealed that the p.R262* would cause no production of protein or a truncated protein lacking five WD40 repeats in the C-terminus; and that p.A211T may interfere with the formation of a deep hydrophobic pocket and thus disturb the binding of CDC20 protein to the substrates of APC/C. This study identified two novel mutations in CDC20, further expanding the mutation spectrum of this gene. Our findings further confirm that biallelic mutations in CDC20 occur in a proportion of infertile females with oocyte maturation abnormality and early embryonic arrest.

Abnormal PIWI-interacting RNA profile and its association with the deformed extracellular matrix of oocytes from recurrent oocyte maturation arrest patients. Fertil Steril 2021; 115:1318-1326.

Abstract
OBJECTIVE To depict the PIWI-interacting RNA (piRNA) profile in oocytes from patients with recurrent oocyte maturation arrest (ROMA) and explore the piRNA candidates associated with the disease. DESIGN An observational study. SETTING Academic research unit. PATIENT(S) Sixteen ROMA patients who provided 140 immature oocytes that arrested at metaphase I, and 146 control patients who provided 420 oocytes for in vitro culture that were collected at the stages of germinal vesicle (GV), metaphase I (MI), and MII. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Expression profiles of piRNA and quantitative reverse-transcription polymerase chain reaction (qRT-PCR) validating data of piR-hsa-17139 and its target genes. RESULT(S) After the piRNA profile was established using piRNA sequencing and hierarchical clustering, the target genes of the piRNA were predicted by bioinformatics databases and matched with mRNA sequencing data. The piRNA expression profiles showed a greater quantity of differentially expressed piRNAs in the older-stage oocytes compared with the early-stage oocytes. The piRNA and mRNA sequencing data indicated that the most affected genes were mainly concentrated in the extracellular matrix (ECM) pathway. Based on the comparison of the piRNA and mRNA sequencing data, four differentially expressed piRNAs were associated with modulation of those ECM pathway genes. The qRT-PCR validation confirmed that piR-hsa-17139 was the only up-regulated piRNA, and its target ECM genes were suppressed in ROMA oocytes. The expression level of piR-hsa-17139 declined slightly while the expression of its target ECM genes plunged dramatically during the development of normal oocytes. CONCLUSION(S) As the important genome monitors in gametogenesis, abnormally expressed piRNAs may affect the expression of ECM modulating genes, which subsequently contributes to ROMA.

Abstract
Background: Ca2+ signaling pathway is suggested to play an essential role in mediating oocyte maturation. Aims: The aim of this study was to evaluate intracellular Ca2+ of resistant immature oocytes that failed to resume meiosis following subsequent in vitro culture reach metaphase II after calcium ionophore A23187 activation. Settings and Design: This in vitro analytical experimental study was conducted at Animal Science Laboratory of Indonesian Medical Education and Research Institute (IMERI), Human Reproductive Infertility and Family Planning of IMERI, and Electrophysiology Imaging of Terpadu Laboratory, Faculty of Medicine, University of Indonesia. Methods: A total of 308 oocytes classed as resistant immature following in vitro culture were randomly allocated to control (n = 113) and treatment groups (n = 195). The oocyte activation group was exposed to A23187 solution for 15 min and then washed extensively. Maturation was evaluated by observing the first polar body extrusion 20‒24 h after A23187 exposure. Ca2+ imaging was conducted using a confocal laser scanning microscope to identify the dynamic of Ca2+ response. Statistical Analysis: SPSS 20, Chi-square, and Mann–Whitney U-test were used in this study. Results: Activation of resistant immature oocytes with A23187 significantly increased the number of oocyte maturation compared with the control group (P < 0.001). Furthermore, fluorescent intensity measurements exhibited a significant increase in the germinal vesicle stage when activated (P = 0.005), as well as the metaphase I stage, even though differences were not significant (P = 0.146). Conclusion: Artificial activation of resistant immature oocyte using chemical A23187/calcimycin was adequate to initiate meiosis progress.

In vitro maturation (IVM) of oocytes in patients with resistant ovary syndrome and in patients with repeated deficient oocyte maturation. J Assist Reprod Genet 2018; 35:2161-2171. [PMID: 30238176 DOI: 10.1007/s10815-018-1317-z] [Citation(s) in RCA: 33] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2018] [Accepted: 09/11/2018] [Indexed: 12/28/2022] Open
Abstract
PURPOSE To assess the efficiency of IVM in patients with repeated ART failure due to resistant ovary syndrome or due to deficient oocyte maturation. METHODS Clinical and laboratory data were obtained retrospectively from 28 patients who underwent 49 cycles of IVM between 2010 and 2017; nine patients had resistant ovary syndrome and 19 patients had repeated deficient oocyte maturation. RESULTS Nine patients with resistant ovary syndrome underwent 24 IVM cycles. In those, an average of 11.5 ± 10.4 cumulus-oocyte complexes (COC) was retrieved, and IVM resulted in 3.4 ± 3.1 mature oocytes. After ICSI and transfer of 23 cleavage-stage embryos, eight pregnancies were obtained, resulting in five healthy live births. The live birth rate was 16.7% per started cycle and 33.3% per patient. Nineteen patients with a history of deficient oocyte maturation underwent 25 IVM cycles. An average of 10.6 ± 9.2 COC was retrieved, and after IVM, 1.3 ± 2.1 oocytes were mature. No mature oocytes were obtained in 11 cycles. In ten cycles with mature oocytes, none of them fertilized after ICSI. Out of four cycles with fertilized oocytes, only one good-quality embryo was obtained. No live births were obtained after IVM in patients with a history of deficient oocyte maturation. CONCLUSIONS Based on our experience, IVM is a valuable approach in patients with resistant ovary syndrome, but should not be recommended for patients with deficient oocyte maturation.
