Induction to tetraploidy in Pacific oysters (Crassostrea gigas)
As an alternative to the use of cytochalasin B (CB), 6-dimethylamino-purine (6-DMAP) and thermal shock (heat shock by increasing the temperature from 25 to 36ºC) could be used to induce tetraploidy in Pacific oyster (Crassostrea gigas) diploids ...

Tetraploidy and tumor development [PDF]
In tumorigenesis, aneuploidy is frequently preceded by tetraploidy. Major issues include how tetraploidy arises and how cells can effectively respond to this state. Two recent papers address these issues. Shi and King demonstrate that nondisjunction of chromosomes in mitosis frequently results in tetraploidy through mitotic cleavage failure.

Tetraploidy causes chromosomal instability in acentriolar mouse embryos
During cell division, tetraploidy can drive chromosomal instability (CIN) via supernumerary centrosomes, but it is unclear if this is the only route to CIN. Here the authors show that, in early mouse embryos, tetraploidy can drive chromosomal instability

Intratumoral patterns of clonal evolution in gliomas [PDF]
Few studies have explored the patterns of clonal evolution in gliomas. Here, we investigate the cytogenetic patterns of intratumoral clonal evolution of gliomas and their impact on tumor histopathology and patient survival.

Tetraploidy and tumor development
Tetraploid cells, which contain a doubled chromosomal content, are known to facilitate tumorigenesis [1]. Two specific characteristics of tetraploid cells play major roles in promoting neoplastic transformation. First, proliferating tetraploid cells are genomically unstable and accumulate both numerical and structural chromosomal abnormalities.

Asymmetric clustering of centrosomes defines the early evolution of tetraploid cells
Tetraploidy has long been of interest to both cell and cancer biologists, partly because of its documented role in tumorigenesis. A common model proposes that the extra centrosomes that are typically acquired during tetraploidization are responsible for ...

Antioxidant defenses during early developmental stages in tetraploid rainbow trout, Oncorhynchus mykiss [PDF]
Antioxidant defense status was examined during early developmental stages of rainbow trout, Oncorhynchus mykiss, as affected by heat shock (HS) treatment to induce tetraploidy.

The fate of extra centrosomes in newly formed tetraploid cells: should I stay, or should I go?
An increase in centrosome number is commonly observed in cancer cells, but the role centrosome amplification plays along with how and when it occurs during cancer development is unclear. One mechanism for generating cancer cells with extra centrosomes is
