NIMA-related kinase 1 (NEK1) regulates meiosis I spindle assembly by altering the balance between α-Adducin and Myosin X.

PLoS ONE, 2017
NIMA-related kinase 1 (NEK1) is a serine/threonine and tyrosine kinase that is highly expressed in mammalian germ cells. Mutations in Nek1 induce anemia, polycystic kidney and infertility.

The Cdc14 Phosphatase and the FEAR Network Control Meiotic Spindle Disassembly and Chromosome Segregation

, 2003
During meiosis, DNA replication is followed by two consecutive rounds of chromosome segregation. Cells lacking the protein phosphatase CDC14 or its regulators, SPO12 and SLK19, undergo only a single meiotic division, with some chromosomes segregating ...

Oocyte Meiotic Spindle Assembly in Caenorhabditis Elegans [PDF]

, 2014
As in many organisms, Caenorhabditis elegans oocytes assemble bipolar meiotic spindles in the absence of centrosomes. While the assembly of the mitotic spindle in C.

In vitro mouse preantral follicle development in 2D and suspension culture: α-MEM vs SAGE 1-step

Reproduction and Fertility
The in vitro culture of immature follicles remains a challenge in reproductive biology, ART, and fertility preservation. This study investigated the impact of α-MEM and SAGE 1-Step media on mouse preantral follicle development and oocyte maturation using

NET1 is a critical regulator of spindle assembly and actin dynamics in mouse oocytes

Reproductive Biology and Endocrinology
Background Neuroepithelial transforming gene 1 (NET1) is a RhoA subfamily guanine nucleotide exchange factor that governs a wide array of biological processes. However, its roles in meiotic oocyte remain unclear.

Inward transport of organelles drives outward migration of the spindle during C. elegans meiosis

Cell Reports
Summary: Cortical positioning of the meiotic spindle within an oocyte is required to expel chromosomes into polar bodies to generate a zygote with the correct number of chromosomes. In C.

Functionality of the spindle checkpoint during the first meiotic division of mammalian oocytes

, 2003
The spindle checkpoint ensures accurate chromosome segregation by delaying anaphase until all chromosomes are correctly aligned on the microtubule spindle.

The muntjac spindle staining assay: An investigation of the ability of this assay to detect potential aneuploidy inducing agents [PDF]

, 1988
This thesis was submitted for the degree of Master of Philosophy and awarded by Brunel University.An assay using muntjac fibroblasts in conjunction with a differential spindle and chromosome stain was developed and evaluated for its ability to detect ...

Asymmetric Division: A Kinesin for Spindle Positioning

, 2005
The meiotic spindles of animal eggs move to extremely asymmetric positions, close to the cell cortex. A recent paper has identified a motor complex that may move the meiotic spindle toward the cortex in Caenorhabditis elegans ...
