Tetraploidy in hydatidiform moles.
STUDY QUESTION How does tetraploidy develop in hydatidiform moles (HMs), and what is the frequency of the different origins? SUMMARY ANSWER Most molar pregnancies with tetraploid cells appear to be produced by somatic endoreduplications, while a minority originate from a tetraploid zygote. The frequency of zygotic tetraploidy was estimated to be 0.7%. WHAT IS KNOWN ALREADY The parental orig...
متن کاملTetraploidy 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. Such chromosomal instability arises mainly due to ...
متن کاملTetraploidy in a liveborn infant.
We report a 3 month old boy with tetraploidy, found in peripheral blood and skin fibroblast cultures, with severely delayed growth and neurodevelopment, and with a cleft lip; these findings have not been described before. This report brings to seven the total number of liveborn infants with a 92,XXYY karyotype.
متن کاملGenetic algebras for tetraploidy with several loci.
The algebra of gamete multiplication corresponding to a population of autotetraploids which differ at n loci, each with an arbitrary number of alleles, is proven to be a genetic algebra, irrespective of the mode of segregation of the n loci.
متن کاملThe consequences of tetraploidy and aneuploidy.
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 division. Tetraploidization can initiate chr...
