Multipolar spindle pole coalescence is a major source of kinetochore mis-attachment and chromosome mis-segregation in cancer cells. [PDF]
PLoS ONE, 2009 Many cancer cells display a CIN (Chromosome Instability) phenotype, by which they exhibit high rates of chromosome loss or gain at each cell cycle. Over the years, a number of different mechanisms, including mitotic spindle multipolarity, cytokinesis ...

Developmental Dynamics, EarlyView.Abstract Background The promoters and enhancers of heat shock genes, such as the 1.5‐kb promoter of the zebrafish hsp70l gene, are valuable tools for temporal activation of transgenes. It has been widely purported that heat shock treatments result in ubiquitous expression of hsp70l‐driven transgenes.

Meiotic behavior of small chromosomes in maize
Frontiers in Plant Science, 2013 The typical behavior of chromosomes in meiosis is that homologous pairs synapse, recombine and then separate at anaphase I. At anaphase II, sister chromatids separate.

Condensin II resolves chromosomal associations to enable anaphase I segregation in Drosophila male meiosis. [PDF]
PLoS Genetics, 2008 Several meiotic processes ensure faithful chromosome segregation to create haploid gametes. Errors to any one of these processes can lead to zygotic aneuploidy with the potential for developmental abnormalities.

Embryonic development of the Mediterranean starfish Hacelia attenuata
Developmental Dynamics, EarlyView.Abstract Background Starfish play essential ecological roles as predators and ecosystem regulators; however, detailed developmental descriptions exist for only a handful of species, none of which are from the Mediterranean Sea. Results In this study, we provide the first full account of the development of the Mediterranean starfish Hacelia attenuata ...

Calpain Proteases and the Evolving Signaling Network in Insect Embryonic Patterning
Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.Insect embryonic Dorsal‐Ventral (DV) patterning relies on the BMP and Toll pathways to different extents. Calcium‐dependent cystein proteases of the Calpain family also exert an important function to pattern the DV axis. In Drosophila, Calpain A cleaves the Cactus/IkappaB inhibitor and modifies Toll signals in ventral regions of the embryo. In Rhodnius

A theoretical model of anaphase
Mathematical BiosciencesThis paper develops a theory for anaphase in cells. After a brief description of microtubules, the mitotic spindle and the centrosome, a mathematical model for anaphase is introduced and developed in the context of the cell cytoplasm and liquid crystalline structures.
