Temporal and Developmental-Stage Variation in the Occurrence of Mitotic Errors in Tripronuclear Human Preimplantation Embryos [Embryo] 22 Aug 2013 | 04:43 pm
Mitotic errors during early development of human preimplantation embryos are common, rendering a large proportion of embryos chromosomally mosaic. It is also known that the percentage of diploid cells...
Fundamental Studies of the Reproductive Biology of the Endangered Persian Onager (Equus hemionus onager) Result in First Wild Equid Offspring from Art... 22 Aug 2013 | 04:43 pm
We studied the Persian onager (Equus hemionus onager), an endangered equid subspecies. The objective was to characterize endocrine patterns and ovarian follicular dynamics of females as well as semina...
Uterine Infusion of Melatonin or Melatonin Receptor Antagonist Alters Ovine Feto-Placental Hemodynamics During Midgestation [Pregnancy] 22 Aug 2013 | 04:43 pm
Dietary melatonin supplementation from mid- to late gestation increases umbilical artery blood flow and causes disproportionate fetal growth. Melatonin receptors have been described throughout the car...
The Canonical WNT2 Pathway and FSH Interact to Regulate Gap Junction Assembly in Mouse Granulosa Cells [Ovary] 22 Aug 2013 | 04:43 pm
WNTs are extracellular signaling molecules that exert their actions through receptors of the frizzled (FZD) family. Previous work indicated that WNT2 regulates cell proliferation in mouse granulosa ce...
Hamster Oviductin Regulates Tyrosine Phosphorylation of Sperm Proteins During In Vitro Capacitation [Female Reproductive Tract] 22 Aug 2013 | 04:43 pm
Oviductin or OVGP1, also known as oviduct-specific glycoprotein, has been shown to enhance sperm capacitation in addition to its other beneficial effects on fertilization and early embryo development....
SOX9 Regulates MicroRNA miR-202-5p/3p Expression During Mouse Testis Differentiation [Testis] 15 Aug 2013 | 06:45 pm
MicroRNAs are important regulators of developmental gene expression, but their contribution to fetal gonad development is not well understood. We have identified the evolutionarily conserved gonadal m...
Regulation of Glucose Phosphate Isomerase by the 3'UTR-Specific miRNAs miR-302b and miR-17-5p in Chicken Primordial Germ Cells [Gamete Biology] 15 Aug 2013 | 06:45 pm
Glucose phosphate isomerase (GPI) involves in the reversible isomerization of glucose-6-phosphate to fructose-6-phosphate in glucose pathways. Because glucose metabolism is crucial for the proliferati...
Identification of Ube2b as a Novel Target of Androgen Receptor in Mouse Sertoli Cells [Mechanisms of Hormone Action] 15 Aug 2013 | 06:45 pm
Many genes are regulated by androgen and its receptor (AR), but the direct target genes of AR, especially those involved in spermatogenesis and male infertility, remain unclear. Here, we identified ub...
Broad Gap Junction Blocker Carbenoxolone Disrupts Uterine Preparation for Embryo Implantation in Mice [Female Reproductive Tract] 15 Aug 2013 | 06:45 pm
Gap junctions have an important role in cell-to-cell communication, a process obviously required for embryo implantation. Uterine luminal epithelium (LE) is the first contact for an implanting embryo ...
Epididymosomes Convey Different Repertoires of MicroRNAs Throughout the Bovine Epididymis [Male Reproductive Tract] 15 Aug 2013 | 06:45 pm
Epididymosomes are small membrane vesicles that are secreted by epididymal epithelial cells and are involved in posttesticular sperm maturation. Although their role in protein transfer to the sperm me...
