APC(FZR1) prevents nondisjunction in mouse oocytes by controlling meiotic spindle assembly timingJanet E Holt
School of Biomedical Sciences, University of Newcastle, Callaghan, NSW 2308, Australia
Mol Biol Cell 23:3970-81. 2012..This study implicates FZR1 as a major regulator of prometaphase whose activity helps to prevent chromosome nondisjunction...
The control of meiotic maturation in mammalian oocytesJanet E Holt
Center for Reproductive Sciences and School of Biomedical Sciences, University of Newcastle, Callaghan, New South Wales, Australia
Curr Top Dev Biol 102:207-26. 2013..This is achieved by APC(CDC20), whose activity is critically regulated by the spindle assembly checkpoint, and which induces both a loss in CDK1 activity as well as the cohesive ties holding chromosomes together...
The APC/C activator FZR1 coordinates the timing of meiotic resumption during prophase I arrest in mammalian oocytesJanet E Holt
School of Biomedical Sciences, University of Newcastle, Callaghan, NSW 2308, Australia
Development 138:905-13. 2011..Thus, APC/C(FZR1) activity is required to repress cyclin B1 levels in oocytes during prophase I arrest in the ovary, thereby maintaining meiotic quiescence until hormonal cues trigger resumption...
Control of homologous chromosome division in the mammalian oocyteJanet E Holt
University of Newcastle, Callaghan, NSW, Australia
Mol Hum Reprod 15:139-47. 2009..In particular, we examine the role played by the spindle assembly checkpoint in controlling the APC/C activity, and in so doing ensuring accurate disjunction of homologs...
Spatial regulation of APCCdh1-induced cyclin B1 degradation maintains G2 arrest in mouse oocytesJanet E Holt
School of Biomedical Sciences, University of Newcastle, Callaghan, NSW 2308, Australia
Development 137:1297-304. 2010..We propose a simple spatial model of G2 arrest in which nuclear APC(Cdh1)-proteasomal activity guards against any cyclin B1 accumulation mediated by nuclear import...
Time-lapse epifluorescence imaging of expressed cRNA to cyclin B1 for studying meiosis I in mouse oocytesJanet E Holt
School of Biomedical Sciences and Pharmacy, University of Newcastle, Callaghan, NSW, Australia
Methods Mol Biol 957:91-106. 2013..Here we describe the process of microinjecting cRNA to proteins of interest that have been coupled to a fluorescent protein using cyclin B1 as an example...
Reduced chromosome cohesion measured by interkinetochore distance is associated with aneuploidy even in oocytes from young miceJulie A Merriman
School of Biomedical Sciences and Pharmacy, University of Newcastle, Callaghan, New South Wales, Australia
Biol Reprod 88:31. 2013..Based on these results, we propose that individual oocytes undergo loss in chromosomal cohesion at different rates and that the greater this loss, the greater the risk for becoming aneuploid...
Identification and characterization of a novel Mt-retrotransposon highly represented in the female mouse germlineJanet E Holt
Reproductive Science Group, Discipline of Biological Science, School of Environmental and Life Sciences, University of Newcastle, Callaghan, NSW 2308, Australia
Genomics 87:490-9. 2006..Together with in silico data, we predict Mtfull plays an essential role in folliculogenesis through regulation of gene expression...
The APC activator fizzy-related-1 (FZR1) is needed for preimplantation mouse embryo developmentMichelle K Y Seah
School of Biomedical Sciences, University of Newcastle, Callaghan, NSW 2308, Australia
J Cell Sci 125:6030-7. 2012....
CXCR4/SDF1 interaction inhibits the primordial to primary follicle transition in the neonatal mouse ovaryJanet E Holt
Reproductive Science Group, Discipline of Biological Science, School of Environmental and Life Sciences, University of Newcastle, Callaghan, NSW 2308, Australia
Dev Biol 293:449-60. 2006..By retaining follicles in an unactivated state, SDF1/CXCR4 signaling may play an important role in maintaining the size and longevity of the primordial follicle pool...
Characterization of structure and expression of the Dzip1 gene in the rat and mouseBenjamin J Curry
Reproductive Science Group, Discipline of Biological Science, School of Environmental and Life Sciences, University of Newcastle, Callaghan, NSW 2308, Australia
Genomics 87:275-85. 2006....
Biosynthesis of the canine zona pellucida requires the integrated participation of both oocytes and granulosa cellsDaniel G Blackmore
Reproductive Science Group, Discipline of Biological Sciences, School of Environmental and Life Sciences, University of Newcastle, Callaghan, New South Wales 2308, Australia
Biol Reprod 71:661-8. 2004....
