Abstract
Zinc plays an essential role in mammalian oocyte maturation, fertilization, and early embryogenesis, and depletion of zinc impairs cell cycle control, asymmetric division, and cytokinesis in oocyte. We report that zinc, via the actin nucleator Spire, acts as an essential regulator of the actin cytoskeleton remodeling during mouse oocyte maturation and fertilization. Depletion of zinc in the mouse oocyte impaired cortical and cytoplasmic actin formation. Spire is colocalized with zinc-containing vesicles via its zinc finger-containing Fab1, YOTB, Vac 1, EEA1 (FYVE) domain. Improper localization of Spire by zinc depletion or mutations in the FYVE domain impair cytoplasmic actin mesh formations and asymmetric division and cytokinesis of oocyte. All 3 major domains of the Spire are required for its proper localization and activity. After fertilization or parthenogenetic activation, Spire localization was dramatically altered following zinc release from the oocyte. Collectively, our data reveal novel roles for zinc in the regulation of the actin nucleator Spire by controlling its localization in mammalian oocyte.-Jo, Y.-J., Lee, I.-W., Jung, S.-M., Kwon, J., Kim, N.-H., Namgoong, S. Spire localization via zinc finger-containing domain is crucial for the asymmetric division of mouse oocyte.

Abstract
The utility of cryopreserved mouse gametes for reproduction of transgenic mice depends on development of assisted reproductive technologies, including vitrification of unfertilized mouse oocytes. Due to hardening of the zona pellucida, spermatozoa are often unable to penetrate vitrified-warmed (V-W) oocytes. Laser-assisted in vitro fertilization (LAIVF) facilitates fertilization by allowing easier penetration of spermatozoa through a perforation in the zona. We investigated the efficiency of V-W C57BL/6NTac oocytes drilled by the XYClone laser, compared to fresh oocytes. By using DAP213 for cryoprotection, 83% (1,470/1,762) of vitrified oocytes were recovered after warming and 78% were viable. Four groups were evaluated for two-cell embryo and live offspring efficiency: 1) LAIVF using V-W oocytes, 2) LAIVF using fresh oocytes, 3) conventional IVF using V-W oocytes and 4) conventional IVF using fresh oocytes. First, the groups were tested using fresh C57BL/6NTac spermatozoa (74% motile, 15 million/ml). LAIVF markedly improved the two-cell embryo efficiency using both V-W (76%, 229/298) and fresh oocytes (69%, 135/197), compared to conventional IVF (7%, 12/182; 6%, 14/235, respectively). Then, frozen-thawed C57BL/6NTac spermatozoa (35% motile, 15 million/ml) were used and LAIVF was again found to enhance fertilization efficiency, with two-cell embryo rates of 87% (298/343) using V-W oocytes (P<0.05, compared to fresh spermatozoa), and 73% (195/266) using fresh oocytes. Conventional IVF with frozen-thawed spermatozoa using V-W (6%, 10/168) and fresh (5%, 15/323) oocytes produced few two-cell embryos. Although live offspring efficiency following embryo transfer was greater with conventional IVF (35%, 18/51; LAIVF: 6%, 50/784), advantage was seen with LAIVF in live offspring obtained from total oocytes (5%, 50/1,010; conventional IVF: 2%, 18/908). Our results demonstrated that zona-drilled V-W mouse oocytes can be used for IVF procedures using both fresh and frozen-thawed spermatozoa, producing live pups. The ability to cryopreserve mouse gametes for LAIVF may facilitate management of large-scale transgenic mouse production facilities.

DNA methylation pattern in mouse oocytes and their in vitro fertilized early embryos: effect of oocyte vitrification. ZYGOTE 2012; 22:138-45.

Abstract
SummaryThis study was conducted to investigate the pattern of DNA methylation in vitrified–thawed mouse oocytes and their in vitro fertilized early embryos. Firstly, mouse oocytes at metaphase II (MII) stage of meiosis were allocated randomly into three groups: (1) untreated (control); (2) exposed to vitrification solution without being plunged into liquid nitrogen (toxicity); or (3) vitrified by open-pulled straw (OPS) method (vitrification). Oocytes from all three groups were fertilized subsequently in vitro. The level of DNA methylation in the MII oocytes and their early embryos was then examined by immunofluorescence using an anti-5-methylcytosine (anti-5-MeC) monoclonal antibody and fluorescein isothiocyanate (FITC)-conjugated goat anti-mouse IgG. Developmental rates to 2-cell embryos (62.28%) and blastocysts (43.68%) of the vitrified–thawed oocytes were lower (P < 0.01) than those of fresh oocytes (81.47%, 61.99%) and vitrification solution treated (79.20%, 60.04%) oocytes. DNA methylation (as reflected by 5-MeC fluorescence intensity) in the vitrification group was less (P < 0.01) for MII oocyte and 2- to 8-cell stages compared with that in the control and toxicity groups. Accordingly, a reduction in global genomic methylation due to vitrification of MII oocytes may result in compromised in vitro developmental potential in early mouse embryos.

Abstract
Vitrification by using two-step exposures to combined cryoprotective agents (CPAs) has become one of the most common methods for oocyte cryopreservation. By quantitatively examining the status of oocytes during CPA additions and dilutions, we can analyze the degree of the associated osmotic damages. The osmotic responses of mouse MII oocyte in the presence of the combined CPAs (ethylene glycol, EG, and dimethyl sulfoxide, DMSO) were recorded and analyzed. A two-parameter model was used in the curve-fitting calculation to determine the values of hydraulic conductivity (L(p)) and permeability (P(s)) to the combined CPAs at 25°C and 37°C. The effects of exposure durations and the exposure temperatures on the cryopreservation in terms of frozen-thawed cell survival rates and subsequent development were examined in a series of cryopreservation experiments. Mouse MII oocytes were exposed to pretreatment solution (PTS) and vitrification solution (VS) at specific temperatures. The PTS used in our experiment was 10% EG and 10% DMSO dissolved in modified PBS (mPBS), and the VS was EDFS30 (15% EG, 15% DMSO, 3 × 10(-3) M Ficoll, and 0.35 M sucrose in mPBS).The accumulative osmotic damage (AOD) and intracellular CPA concentrations were calculated under the different cryopreservation conditions, and for the first time, the quantitative interactions between survival rates, subsequent development rates, and values of AOD were investigated.

Abstract
PURPOSE to determine the effect of cryopreservation on acH4K12 in oocytes and their respective zygotes. METHODS AcH4K12 in fresh or vitrified-warmed oocytes and their respective zygotes at 70 min-12 h post-fertilization were assessed using fluorescent staining. RESULTS 1. AcH4K12 levels increased significantly in vitrified oocytes compared to controls. 2. Respective zygotes derived from vitrified oocytes had abnormal chromatin distribution or acH4K12 patterns before and after pronuclear formation. CONCLUSION Cryopreservation alters AcH4K12 patterns in oocytes, which subsequently affect the chromatin distribution and acH4K12 in fertilized oocytes.

Abstract
A major challenge of assisted reproduction technologies (ARTs) is to mimic the natural environment required to sustain oocyte and embryo survival. Herein, we show that the ceramide-metabolizing enzyme, acid ceramidase (AC), is expressed in human cumulus cells and follicular fluid, essential components of this environment, and that the levels of this enzyme are positively correlated with the quality of human embryos formed in vitro. These observations led us to develop a new approach for oocyte and embryo culture that markedly improved the outcome of in vitro fertilization (IVF). The addition of recombinant AC (rAC) to human and mouse oocyte culture medium maintained their healthy morphology in vitro. Following fertilization, the number of mouse embryos formed in the presence of rAC also was improved (from approximately 40 to 88%), leading to approximately 5-fold more healthy births. To confirm these observations, immature bovine oocytes were matured in vitro and subjected to IVF in the presence of rAC. Significantly more high-grade blastocysts were formed, and the number of morphologically intact, hatched embryos was increased from approximately 24 to 70%. Overall, these data identify AC as an important component of the in vivo oocyte and embryo environment, and provide a novel technology for enhancing the outcome of assisted fertilization. Eliyahu, E., Shtraizent, N., Martinuzzi, K., Barritt, J., He, X., Wei, H., Chaubal, S., Copperman, A. B., Schuchman, E. H. Acid ceramidase improves the quality of oocytes and embryos and the outcome of in vitro fertilization.
