Transcriptional profiling of cumulus cells differentiation throughout oocyte competence acquisition in the bovine ovarian follicles.

ABSTRACT: Somatic cells surrounding the oocyte were sampled at the following stages: developmentally incompetent or poorly competent prophase I oocytes (NC1 oocytes), developmentally competent prophase I oocytes (C1 oocytes), and developmentally competent metaphase II oocytes (C2 oocytes). NC1 cumulus cells (CC) were sampled from immature calf oocytes, C1 samples from immature cow oocytes, and C2 samples from in vivo matured cow oocytes. Global transcriptional profiling was performed using cumulus cells collected from bovine ovarian follicles during in vivo oocyte developmental competence acquisition. Cumulus cells were collected at 3 stages: early stage follicles (prophase I arrested oocytes, meiotically competent but developmentally incompetent, n=6), late stage follicles (prophase I arrested oocytes, meiotically competent and developmentally competent, n=6) and ovulatory follicles collected by ovum pick-up (OPU) in vivo (metaphase II arrested oocytes, developmentally fully competent, n=5).

Transcriptional profiling of cumulus cells differentiation throughout oocyte competence acquisition in the murine ovarian follicles.

Project description:Cumulus cells surrounding the oocyte were sampled at the following stages: developmentally incompetent or poorly competent prophase I oocytes (NC1 oocytes), developmentally competent prophase I oocytes (C1 oocytes), and developmentally competent metaphase II oocytes (C2 oocytes). NC1 samples were collected from immature, unexpanded cumulus-oocytes complexes (COC) from prepubertal (3-week-old) mice, C1 samples from immature, unexpanded cumulus-oocytes complexes (COC) from adult (8-week-old) and C2 samples from mature, expanded COCs obtained from the oviduct from 8-week-old mice after standard superovulation protocol. Global transcriptional profiling was performed using cumulus cells collected from murine ovarian follicles during in vivo oocyte developmental competence acquisition. Cumulus cells were collected at 3 stages: early stage follicles (prophase I arrested oocytes, meiotically competent but developmentally incompetent, n=5), late stage follicles (prophase I arrested oocytes, meiotically competent and developmentally competent, n=5) and ovulatory follicles collected in vivo (metaphase II arrested oocytes, developmentally fully competent, n=5).

Transcriptional profiling of somatic cells differentiation throughout oocyte competence acquisition in rainbow trout ovarian follicles.

Project description:Somatic cells surrounding the oocyte were sampled at the following stages: developmentally incompetent or poorly competent prophase I oocytes (NC1 oocytes), developmentally competent prophase I oocytes (C1 oocytes), and developmentally competent metaphase II oocytes (C2 oocytes). NC1 samples were collected from late vitellogenic females (LV), C1 samples from post-vitellogenic females (PV), and C2 samples from females undergoing meiotic maturation (Germinal Vesicle Breakdown) Global transcriptional profiling was performed using somatic cells collected from rainbow trout ovarian follicles during in vivo oocyte developmental competence acquisition. Somatic cells were collected at 3 stages of oogenesis: NC1 stage follicles (LV, late vitellogenic, prophase I arrested oocytes, meiotically incompetent and developmentally incompetent, n=6), C1 stage follicles (PV, post-vitellogenic, prophase I arrested oocytes, meiotically competent and developmentally competent, n=16). Ovulatory follicles were also collected during oocyte maturation after in vivo induction (metaphase II arrested oocytes, developmentally fully competent, n=6).

Transcriptional profiling of somatic cells differentiation throughout oocyte competence acquisition in the xenopus ovarian follicles.

Project description:Somatic cells surrounding the oocyte were sampled at the following stages: developmentally incompetent or poorly competent prophase I oocytes (NC1 oocytes), developmentally competent prophase I oocytes (C1 oocytes), and developmentally competent metaphase II oocytes (C2 oocytes). NC1 samples were collected from immature stage IV follicles, C1 samples from immature stage VI follicles, and C2 samples from in vitro matured stage VI follicles. Global transcriptional profiling was performed using somatic cells collected from xenopus ovarian follicles during in vivo oocyte developmental competence acquisition. Somatic cells were collected at 3 stages of oogenesis: early stage follicles (stage IV, vitellogenic, prophase I arrested oocytes, meiotically competent but developmentally incompetent, n=5), late stage follicles (stage VI, post-vitellogenic, prophase I arrested oocytes, meiotically competent and developmentally competent, n=5) and ovulatory follicles collected after in vitro maturation induction with hCG of post-vitellogenic follicles (metaphase II arrested oocytes, developmentally fully competent, n=5).

The E2 SUMO-conjugating enzyme UBE2I is essential for chromatin dynamics and transcriptional silencing in mouse oocytes

Project description:In mammals, meiotically competent oocytes develop cyclically during ovarian folliculogenesis. During their development, prophase I arrested oocytes are highly transcriptionally active in preparation for the resumption of meiosis and early stages of embryogenesis prior to the maternal to zygotic transition. Defective oocyte development during folliculogenesis leads to meiotic defects, aneuploidy, follicular atresia, or non-viable embryos. SUMOylation, a dynamic post-translational protein modification, is essential for oocyte development during folliculogenesis and to regulate meiotic maturation in mice. We generated a novel oocyte-specific knockout of Ube2i, the sole SUMO E2 ligase, to test its role growing ovarian follicles using Zp3-cre. Ube2i Zp3-cre+ female mice are sterile with oocytes with defects in meiotic progression but not meiotic resumption. Importantly, fully grown oocytes do not silence transcription and prematurely activate the zygotic transcriptional program. This work uncovers unknown functions of UBE2i as a key orchestrator of chromatin and transcriptional regulation in oocytes.

Transcriptional profiling of cumulus cells entoured the oocyte after in vitro or in vivo maturation in bovine (Bos taurus)

Project description:In vitro maturation (IVM) of the oocytes is a routine method in bovine embryo production. The competence of bovine oocytes to develop into embryo after IVM and in vitro fertilization (IVF) is lower as compared to in vivo preovulatory oocytes. Cumulus cells (CC) that enclose an oocyte are involved in the acquisition of oocyte quality during maturation. Using transcriptomic approach we compared cumulus cells gene expression during IVM with that in vivo preovulatory period. Global transcriptional profiling was performed using cumulus cells collected from mature bovine oocytes (metaphase-II stage) after maturation performed either in vivo or in vitro. In vivo matured cumulus cells were collected from ovulatory follicles of Montbeliard adult cows by ovum pick-up in vivo (OPU, n=4). In vitro matured cumulus cells were recovered from the oocytes after 22h of in vitro culture of cumulus-oocyte complexes (50 COC per experiment) from 2-6 mm ovarian follicles of adult cows (MIV, n=4). Gene expression analysis was carried out between in vivo and in vitro matured cumulus representing a total of 8 slides (dye swap protocol)

Understanding bovine germinal vesicle (GV) oocyte and cumulus cell communication... A systems biology approach

Project description:Triplicate samples of oocyte and cumulus cells were isolated from follicles of 2-8 mm, containing oocytes with several layers of cumulus cells were collected from ovaries. Proteins were extracted using DDF and digested using trypsin. The peptides were desalted, separated using in-line SCX-RPLC and analyzed using ion trap MS/MS. Proteins were identified using TurboSEQUEST 3.2
