Increased environment-related metabolism and genetic expression in the in vitro matured mouse oocytes by transcriptome analysis

Project description:Infertility is a world-wide problem for the human at reproductive age, and oocyte in vitro maturation (IVM) is generally applied to acquire the embryo in assisted reproductive technology (ART) for this issue. However, it is still unclear for the differences of RNA expression profile in the oocytes between in vivo (IVO) and IVM culture environment. In this study, we compared the global RNA transcription pattern of oocytes from in vitro and in vivo maturation in mouse. Our results showed that 1864 genes differentially expressed between the IVO and IVM oocytes. Among these 1638 genes were up-regulated and 226 genes were down-regulated, and these changes were mainly divided into environmental adaption, metabolism and genetic expression. Our detailed analysis showed that the expression of genes which belong to metabolism-related processes such as energy metabolism, nucleotide metabolism and carbohydrate metabolism was changed; and these genes were also belonged to organismal systems including environmental adaptation and circulatory system; moreover, we also found that the relative gene expression of genetic expression processes, such as protein synthesis, modification, and DNA replication and repair were also altered. In conclusion, our data suggest that in vitro maturation of mouse oocyte resulted in metabolism and genetic expression changes by environmental changes compared with in vivo matured oocytes.

RNAseq of the in vitro matured and in vivo matured monkey oocytes

Project description:Oocyte quality largely determines the embryo development after fertilization. High-quality oocyte requires the competence of both cytoplasm and nucleus. However, clinically, the treatment of developmentally competent oocytes was limited. Here, in order to improve the embryo development efficiency of developmentally incompetent oocytes, we performed spindle-chromosome complex (SCC) transfer between in vitro matured (IVM) and in vivo matured (IVO) oocytes of the non-human primate. We observed that the blastocyst rate of embryos derived by transferring the SCC of IVM (IVM-SCC) oocytes into enucleated IVO oocytes was comparable with that of embryos derived by IVO oocytes. After transferring the reconstructed embryos into the uterus of surrogate mothers, two live rhesus monkeys were obtained, indicating that the nuclei of IVM oocytes support both the pre-and post-implantation embryo development of non-human primates.

Microarray data of prepubertal, peripubertal, and adult oocytes, and from GV and MII oocytes matured in vivo or in vitro

Project description:Expression data from prepubertal, peripubertal, and adult derived mouse oocytes, and from germinal vesicle (GV), in vivo matured, and in vitro matured mouse oocytes. Oocytes derived from prepubertal females, or oocytes matured in vitro, are less developmentally competent compared to adult derived, or in vivo matured, oocytes, indicated by decreased embryonic development. One potential mechanism for decreased developmental potetential in prepubertal or in vitro matured oocytes is inadequate or inappropriate RNA degradation during oocyte maturation (progression from GV to MII). To investigate mechanisms involved in establishing oocyte cytoplasmic maturation and developmental competence, Affymetrix GeneChip microarrays were used. Keywords: Oocyte developmental competence The study encompassed three experimental designs using female B6D2F1 mice: 1) In vitro matured oocytes were obtained from d20 (prepubertal), d26 (peripubertal), and 7-8 wk old (adult) mice; 2) in vivo and in vitro matured oocytes were obtained from d26 mice; and 3) GV, in vivo matured, and in vitro matured oocytes were obtained from 7-8 wk old mice. RNA was extracted from pools of 150 oocytes and hybridized onto the Affymetrix microarrays.

Gene Expression Profiles in Immature and In vitro matured bovine Oocytes

Project description:In cattle, almost all fully grown vesicle stage oocytes (GV) have the ability to resume meisos, develop to Metaphase II stage (MII), support fertilization and progress through the early embryonic cycles in vitro. Yet without intensive selection, the majority fail to develop to the blastocyst stage. Using the Affymetrix Bovine Genome Array, global mRNA expression analysis of immature (GV) and in vitro matured (IVM) bovine oocytes was carried out to characterize the transcriptome of the bovine oocyte and to identify the key pathways associated with oocyte meiotic maturation and developmental potential. Immature and in vitro matured bovine oocytes were collected for RNA extraction and hybridization on Affymetrix GeneChip Bovine Genome array. Careful removal of cumulus and selection of oocytes was carried out under the stereo microscope in order to examine the actual cumulus-free temporal oocyte gene expression profiles. Immature oocytes at time 0 h and in vitro matured oocytes at 24 h were collected for analysis.

Gene expression profile of in vivo and in vitro matured human oocytes revealed by microarray analysis

Project description:Four groups of human oocytes from in vitro fertilization programme were analysed using microarrays: 1.) oocytes matured in vivo (retrieved as mature by ultrasound follicular aspiration but not fertilized after in vitro fertilization), 2.) oocytes matured in vitro in a conventional way (in a maturation medium with added gonadotropins FSH and HCG), 3.) oocytes matured in vitro by a new approach (in a maturation medium with added gonadotropins FSH and HCG, and in a co-culture with cumulus cells from mature oocytes of the same patient), and 4.) not matured oocytes which did not mature in spite of in vitro maturation procedure. Each group of oocytes consisted of three biological replicates with 10 oocytes per replicate therefore 12 oocyte samples and altogether 120 human oocytes were analyzed by microarrays.

Gene expression profiling of in vitro matured bovine oocytes cultivated with or without cumulus cells.

Project description:Cumulus cells, surrounding the oocyte, play a key role in the acquisition of oocyte competence to be fertilized and to sustain early embryo development. Cumulus cells contribute to oocyte development by metabolizing energy substrates such as glutathione that may protect the oocyte from oxidative stress damages. The aim of our study was to compare transcriptomics profiles of cumulus enclosed (CEO) and cumulus denuded (CDO) oocytes after in vitro maturation. Global transcriptional profiling was performed using cumulus enclosed and cumulus denuded oocytes after in vitro maturation. Matured oocytes were obtained after 22h of maturation with (CEO) or without (CDO) cumulus cells and four replicates of 25 oocytes were collected for RNA extraction. Gene expression analysis was performed by comparing CDO versus CEO oocytes that represents a total of 8 slides using a dye swap hybridisation protocol.
