Chromosome numbers of Chilean pteridophytes: First contribution [PDF]
, 2012 Mitotic chromosome counts in Chilean pteridophytes confirm the diploidy described for Equisetum L. (2n = 216) and Blechnum L. (2n = 66), as well as the tetraploidy of Asplenium L. (2n = 144). Megalastrum spectabile (Kaulf.) A.R.Sm.

Genetic Evidence for p75NTR-Dependent Tetraploidy in Cortical Projection Neurons from Adult Mice [PDF]
, 2013 A subpopulation of chick retinal projection neurons becomes tetraploid during development, an event prevented by blocking antibodies against p75 neurotrophin receptor (p75(NTR)).

The Influence of Polyploidy and Genome Composition on Genomic Imprinting in Mice [PDF]
, 2016 Genomic imprinting is an epigenetic mechanism that switches the expression of imprinted genes involved in normal embryonic growth and development in a parent-of-origin-specific manner.

Tetraploidy causes chromosomal instability in acentriolar mouse embryos
Nature Communications, 2019 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

Antioxidant defenses during early developmental stages in tetraploid rainbow trout, Oncorhynchus mykiss [PDF]
Caspian Journal of Environmental Sciences, 2023 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 negative interplay between Aurora A/B and BRCA1/2 controls cancer cell growth and tumorigenesis via distinct regulation of cell cycle progression, cytokinesis, and tetraploidy [PDF]
, 2014 It is well known that the activation of Aurora A/B (Aur A/B) or inactivation of BRCA1/2 induces tumor formation. Others and we have reported that the mutual suppression between Aur A/B and BRCA1/2 may manipulate cancer cell growth and tumorigenesis ...

The fate of extra centrosomes in newly formed tetraploid cells: should I stay, or should I go?
Frontiers in Cell and Developmental Biology, 2023 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

Reversible Tetraploidy as an Evolutionary Mechanism [PDF]
Evolution, 1971 Polyploidization is reversible. Randolph and Fischer (1939) obtained diploid offspring from autotetraploid maize. Several fertile haploids have also been obtained from successful tetraploid and octaploid species (Kimber and Riley, 1963; de Wet and Harlan, 1970), and Raven and Thompson (1964) pointed out that there is no experimental basis or ...
