Tetraploidy and Hymenoptera [PDF]
Nature, 1936 A COMMUNICATION1 from B. R. Speicher has directed attention to certain genetical data which do not seem to favour my suggestion2 that the pre-conjugation phenomena observed in the gametogenesis of the honey bee and of Cynips kollari may be interpreted in terms of derived tetraploidy.

Tetraploidy in a liveborn infant. [PDF]
Journal of Medical Genetics, 1976 A congenitally malformed infant with a tetraploid chromosome complement who survived to 1 year of age is reported. The relationship of the polyploidy and the anomalies is discussed.

Near-tetraploidy is associated with Richter transformation in chronic lymphocytic leukemia patients receiving ibrutinib [PDF]
Blood Advances, 2017 : Ibrutinib is a highly effective targeted therapy for chronic lymphocytic leukemia (CLL). However, ibrutinib must be discontinued in a subset of patients due to progressive CLL or transformation to aggressive lymphoma (Richter transformation ...

Tetraploidy and tumor development
Oncotarget, 2014 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.

Induced Tetraploidy in Melandrium album [PDF]
Nature, 1938 IN the flowering plants, the problem of polyploidy in relation to diœcism is an extraordinarily attractive one, since it should be possible in this way to get additional proof of the balance theory of sex determination.

Tetraploidy in a liveborn infant. [PDF]
Journal of Medical Genetics, 1990 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.

Tetraploidy in hydatidiform moles [PDF]
Human Reproduction, 2013 How does tetraploidy develop in hydatidiform moles (HMs), and what is the frequency of the different origins?Most molar pregnancies with tetraploid cells appear to be produced by somatic endoreduplications, while a minority originate from a tetraploid zygote.

Tetraploidy and CIN: a dangerous combination [PDF]
Cell Cycle, 2015 Chromosomal instability (CIN) is a hallmark of cancer, and is associated with both poor prognosis and drug resistance.1 Tetraploidy has also been frequently observed in human cancer despite being a...

Long‐term survival of an infant with complete tetraploidy: A case report [PDF]
American Journal of Medical Genetics Part A, Volume 194, Issue 11, November 2024.Abstract We present the case of a girl with complete tetraploidy who has survived to her present age of 4 years and 1 month. Infants with complete tetraploidy have been described to have a limited lifespan owing to complications. We report her characteristics, medical history, and development.
