p53: Guardian of ploidy

Molecular Oncology, 2011
Aneuploidy, often preceded by tetraploidy, is one of the hallmarks of solid tumors. Indeed, both aneuploidy and tetraploidy are oncogenic occurrences that are sufficient to drive neoplastic transformation and cancer progression.

Variations in morphological, biochemical and phytochemical traits of diploid and induced tetraploid plants of downy thorn-apple (Datura innoxia Mill.)

Journal of Medicinal Plants, 2022
Background: Datura species produce a wide range of tropane alkaloids with medicinal values. D. innoxia is a species of the Datura genus which is poisonous and has an unpleasant odor due to the presence of tropane alkaloids.

The Induction of Tetraploidy in Salmonids

Journal of the World Aquaculture Society, 1986
AbstractThe induction of tetraploidy was attempted in three intraspecies crosses (autotetraploid) of sal‐monid: chinook salmon (Oncorhynchus tshawytscha), coho salmon (O. kisutch) and rainbow trout (Salmo gairdneri), and in the interspecies hybrid (allotetraploid) coho × Atlantic salmon (Salmo salar).Pressure treatments of 6.2 × 104 kPa (9,000 psi ...

Tetraploidy-associated centrosome overduplication in mouse early embryos

Communicative & Integrative Biology, 2018
Recently, we observed that tetraploidization of certain types of human cancer cells resulted in upregulation of centrosome duplication cycles and chronic generation of the extra centrosome. Here, we investigated whether tetraploidy-linked upregulation of

Gametogenesis and nucleotypic effects in the tetraploid red vizcacha rat, Tympanoctomys barrerae (Rodentia, Octodontidae)

Biological Research, 2004
Nucleotypic effects link DNA content with nuclear size and cell dimensions of reproductive cells in polyploid organisms. We studied the gametogenesis of the allotetraploid rodent Tympanoctomys barrerae, aiming to determine these effects in reproductive ...
