The purpose of this study was to evaluate the ability of hyaluronic acid to improve the development of 1- and 2-cell porcine embryos to the blastocyst stage in a simple medium. In Experiment 1, we confirmed the ability of Whitten's medium supplemented with 15 mg/ml BSA to support the development of porcine embryos to the blastocyst stage under our(More)
BACKGROUND/AIM The significance of indocyanine green (ICG) angiography (ICGA) in Harada's disease still awaits clarification in many respects. This study investigates the details of choroidal lesions observed in Harada's disease by the subtraction method. METHODS Eight patients with Harada's disease were followed with ICGA. ICG angiograms were obtained(More)
We examined the effects of four glycosaminoglycans (GAGs) on the development of in vitro-matured (IVM) and -fertilized (IVF) porcine oocytes to the blastocyst stage. IVM and IVF oocytes were cultured in Whitten's medium supplemented with hyaluronic acid, chondroitin sulfate A, dermatan sulfate, or heparin at 38.5 degrees C in an atmosphere of 5% CO2 in(More)
Although pronuclear DNA micro-injection has long been the most reliable method to produce transgenic pigs, the efficiency of production of transgenic offspring is generally plagued by 1% of the DNA-injected embryos. Therefore, a problem with this method is the need for large numbers of pronuclear stage embryos. One great advancement would be the use of in(More)
Full-grown oocytes arrested at germinal vesicle stage contain many dormant maternal mRNAs, and Aurora A has been reported to play a key role for the translation of these maternal mRNAs in Xenopus oocytes. Although the presence of Aurora A has been reported in mammals, the functions of Aurora A on the protein synthesis and the meiotic resumption have never(More)
INTRODUCTION Latanoprostene bunod (LBN) is a novel nitric oxide (NO)-donating prostaglandin F2α analog. We evaluated the long-term safety and intraocular pressure (IOP)-lowering efficacy of LBN ophthalmic solution 0.024% over 1 year in Japanese subjects with open-angle glaucoma (OAG) or ocular hypertension (OHT). METHODS This was a single-arm,(More)
Smallie (slie), a spontaneous, autosomal-recessive mutation causes dwarfing and infertility in mice. The purpose of this study was to determine and characterize the underlying molecular genetic basis for its phenotype. The slie locus was mapped to chromosome 1, and fine-structure mapping narrowed the slie allele within 2 Mb between genetic markers D1Mit36(More)
Histone acetylation plays an important role in the regulation of chromatin structure and gene function. In mammalian oocytes, histones H3 and H4 are highly acetylated during the germinal vesicle (GV) stage, and global histone deacetylation takes place via a histone deacetylase (HDAC)-dependent mechanism after GV breakdown (GVBD). The presence of HDACs in(More)
Cell division cycle 20 (CDC20) and fizzy/cell division cycle 20 related 1 (FZR1) are activators of the anaphase-promoting complex (APC), which ubiquitinates M-phase regulating proteins, such as cyclin B and securin, and induces their degradation. In the present study, porcine CDC20 and FZR1 were cloned by reverse transcriptase-polymerase chain reaction, and(More)
Mice homozygous for the smallie (slie) mutation lack a collagen receptor, discoidin domain receptor 2 (DDR2), and are dwarfed and infertile due to peripheral dysregulation of the endocrine system of unknown etiology. We used a systems biology approach to identify biological networks affected by Ddr2(slie/slie) mutation in ovaries using microarray analysis(More)
