MTOR (mechanistic target of rapamycin) is a widely recognized integrator of signals and pathways key for cellular metabolism, proliferation, and differentiation. Here we show that conditional knockout (cKO) of <i>Mtor</i> in either primordial or growing oocytes caused infertility but differentially affected oocyte quality, granulosa cell fate, and follicular development. cKO of <i>Mtor</i> in nongrowing primordial oocytes caused defective follicular development leading to progressive degeneratio ...[more]

Oocyte stage-specific effects of MTOR determine granulosa cell fate and oocyte quality in mice.

Project description:MTOR (mechanistic target of rapamycin) is a widely recognized integrator of signals and pathways key for cellular metabolism, proliferation, and differentiation. Here we show that conditional knockout (cKO) of Mtor in either primordial or growing oocytes caused infertility but differentially affected oocyte quality, granulosa cell fate, and follicular development. cKO of Mtor in nongrowing primordial oocytes caused defective follicular development leading to progressive degeneration of oocytes and loss of granulosa cell identity coincident with the acquisition of immature Sertoli cell-like characteristics. Although Mtor was deleted at the primordial oocyte stage, DNA damage accumulated in oocytes during their later growth, and there was a marked alteration of the transcriptome in the few oocytes that achieved the fully grown stage. Although oocyte quality and fertility were also compromised when Mtor was deleted after oocytes had begun to grow, these occurred without overtly affecting folliculogenesis or the oocyte transcriptome. Nevertheless, there was a significant change in a cohort of proteins in mature oocytes. In particular, down-regulation of PRC1 (protein regulator of cytokinesis 1) impaired completion of the first meiotic division. Therefore, MTOR-dependent pathways in primordial or growing oocytes differentially affected downstream processes including follicular development, sex-specific identity of early granulosa cells, maintenance of oocyte genome integrity, oocyte gene expression, meiosis, and preimplantation developmental competence.

Human oocyte proteome and secretome

Project description:The proteome and secretome of human oocytes was studied by shotgun LCMSMS, starting from pools of 100 cells. Exploiting SP3, a novel technology for proteomic sample preparation using magnetic beads, we scaled down proteome analysis to single cells. Despite the low protein content of only ~100ng per cell, we consistently identified ~450 proteins from individual oocytes. When comparing proteomes of individual oocytes at the germinal vesicle (GV) and metaphase II (MII) stage by label-free quantification, we found several proteins preferentially expressed in matuare and immature cells. This study demonstrates that an innovative proteomics workflow facilitates analysis of single human oocytes to investigate human oocyte biology and pre-implantation development. The approach presented here paves the way for quantitative proteomics in other quantity-limited tissues and cell types.

Effects of in vitro maturation on oocyte gene expression

Project description:In vitro oocyte maturation (IVM) holds great promise as a tool for enhancing clinical treatment of infertility, enhancing availability of non human primates for development of disease models, and facilitating endangered species preservation. However, IVM outcomes have remained significantly below success rates obtained using in vivo matured (VVM) oocytes from humans and non human primates. A cDNA array based analysis is presented, comparing the transcriptomes of VVM oocytes with IVM oocytes. We observe a small set of just 59 mRNAs that are differentially expressed between the two cell types. These mRNAs are related to cellular homeostasis, cell-cell interactions including growth factor and hormone stimulation and cell adhesion, and other functions such as mRNA stability and translation. Additionally, we observe in IVM oocytes overexpression of PLAGL1 and MEST, two maternally imprinted genes, indicating a possible interruption or loss of correct epigenetic programming. These results indicate that, under certain IVM conditions, oocytes that are molecularly highly similar to VVM oocytes can be obtained, however the interruption of normal oocyte-somatic cell interactions during the final hours of oocyte maturation may preclude the establishment of full developmental competence.

Proteomic-based identification of oocyte maturation-related proteins in mouse GV oocytes

Project description:In this study, we applied 1D SDS-PAGE and RP-LC-MS/MS to investigate the proteins stored in GV mouse oocytes. This high-performance strategy allowed us to define a set of 1405 different mouse GV oocyte proteins. It is confirmed that this study will help us to understand the diverse biological processes occurring in mouse oocytes and during early embryo development. However, compared with proteomic analysis of other cells and tissues, such as embryonic stems from cells and liver, the proteins identified in mature mouse oocytes were limited. This was mainly due to the fact that oocytes obtained from each mouse were very limited. We believe that the catalog of maternal proteins presented in this article is a starting point and we anticipate that more researches on the oocyte proteome will deduce most of the maternal proteins.

Evaluation of ribonucleic acid amplification protocols for human oocyte transcriptome analysis

Project description:Objective: To develop a reliable, reproducible, and sensitive method for investigating gene-expression profiles from individual human oocytes. Setting: University medical center and university microarray laboratory. Patient(s): Couples undergoing intracytoplasmic sperm injection treatment were asked to donate their immature oocytes for research, and written informed consent was obtained in all cases. Seventy-nine human oocytes were used in total. Intervention(s): None. Main Outcome Measure(s): Amplification efficiency and microarray profiles. Result(s): Two of the five protocols (WT-Ovation One-Direct and Arcturus RiboAMp HS Plus) resulted in sufficient yields and high success rates and were further validated for their performance in obtaining reliable, reproducible, and sensitive expression profiles from individual human oocytes. Evaluation of these two protocols demonstrated that they both displayed low technical variation and produced highly reproducible profiles (r R 0.95). One of them identified significantly more transcripts but also had a higher number of false discoveries. Conclusion(s): Two protocols generated ample amounts of mRNA for (quantitative) polymerase chain reaction, microarray, and sequencing techniques. Further validation using a design that discriminates between biological and technical variation showed that both protocols can be used for gene-expression profiling of individual human oocytes. Design: Five commercially available protocols were investigated for their efficiency to amplify messenger RNA (mRNA) from 54 single human oocytes. Protocols resulting in sufficient yields were further validated using microarray technology. For the validation, mRNA was isolated from 25 human oocytes. To eliminate biological variation, RNA from 13 human oocytes was pooled together and split into 12 identical samples for further mRNA amplification. From 12 oocytes, mRNA was individually isolated.

Microarray analysis of the oocyte quality

Project description:Microarray analysis was performed in ooplast samples to identify gene expression profiles associated with the embryo capacity to develop to blastocyst stage A fraction of the cytoplasm from in vitro matured oocytes was collected and snap frozen. The oocytes were chemically activated and presumptive zygotes were in vitro cultured in individual medium microdrops. The embryo development was recorded and oocytes classified according to the stage of embryo development. Oocyte was considered of good quality if the development proceeded to blastocyst stage, whereas it was considered of bad quality if there was a development block between 8-16 cells stage and morula formation.
