Cloning and sequence analysis of Sox genes in a tetraploid cyprinid fish, Tor douronensis [PDF]

open access: yes, 2008
A PCR survey for Sox genes in a young tetraploid fish Tor douronensis (Teleostei: Cyprinidae) was performed to access the evolutionary fates of important functional genes after genome duplication caused by polyploidization event.

Addressing a weakness of anticancer therapy with mitosis inhibitors: Mitotic slippage

open access: yesMolecular & Cellular Oncology, 2017
Mitosis inhibitors, which include antimicrotubule drugs, are chemotherapy agents that induce the arrest and apoptosis of mitotic cells. Mitotic slippage, in which mitotically arrested cells exit mitosis, limits the effectiveness of mitosis inhibitors. We

An Emerging Animal Model for Querying the Role of Whole Genome Duplication in Development, Evolution, and Disease

open access: yesJournal of Developmental Biology, 2023
Whole genome duplication (WGD) or polyploidization can occur at the cellular, tissue, and organismal levels. At the cellular level, tetraploidization has been proposed as a driver of aneuploidy and genome instability and correlates strongly with cancer ...

100 Years of Chromosome Research in Rye, Secale L.

open access: yesPlants, 2022
Although microscopy and genetics were still in their infancy, there are cytological results produced a hundred years ago that are still relevant today. Since the 1920s, rye has been a subject of chromosome research. It started by plotting its mitotic and

Chromosome numbers of Chilean pteridophytes: First contribution [PDF]

open access: yes, 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.

Comparative cytogenetics of anembryonic pregnancies and missed abortions in human

open access: yesВавиловский журнал генетики и селекции, 2023
Miscarriage is an important problem in human reproduction, affecting 10–15 % of clinically recognized pregnancies. The cases of embryonic death can be divided into missed abortion (MA), for which the ultrasound sign of the embryo death is the absence of ...

The consequences of tetraploidy and aneuploidy [PDF]

open access: yesJournal of Cell Science, 2008
Polyploidy, an increased number of chromosome sets, is a surprisingly common phenomenon in nature, particularly in plants and fungi. In humans, polyploidy often occurs in specific tissues as part of terminal differentiation. Changes in ploidy can also result from pathophysiological events that are caused by viral-induced cell fusion or erroneous cell ...
