Polyploidy - Wikipedia
网页Polyploidy occurs in humans in the form of triploidy, with 69 chromosomes (sometimes called 69, XXX), and tetraploidy with 92 chromosomes (sometimes called 92, XXXX).

Tetraploidy in the era of molecular karyotyping – What we need …
网页2013年9月1日 · Tetraploidy is a condition in which there are four complete sets of chromosomes in a single cell. In humans, this would be 92 sets of chromosomes per cell, i.e., 92,XXXX (in females) or 92,XXYY (in males). The most probable origin of tetraploidy is chromosome duplication in a somatic cell in an early-cleavage-stage embryo, a …
Tetraploidy - an overview | ScienceDirect Topics
网页Tetraploidy refers to the presence of twice the normal number of chromosomes in a cell (4n). Because cells can be tetraploid during mitosis, tetraploidy is considered abnormal if more than a certain fraction of the overall cell population is tetraploid (typically >6% [31] ).
Tetraploidy in cancer and its possible link to aging - PMC
网页2018年7月26日 · Here, we review recent findings about how tetraploidy is related to cancer and possibly to aging, and discuss underlying mechanisms of the relationship, as well as how we can exploit the properties of cells exhibiting tetraploidy‐induced CIN to control these pathological conditions.
Tetraploidy - an overview | ScienceDirect Topics
网页Tetraploidy refers to a rare chromosomal abnormality characterized by the presence of four sets of chromosomes instead of the usual two sets. It is often associated with multiple congenital anomalies and is typically not compatible with …
The consequences of tetraploidy and aneuploidy
网页2008年12月1日 · Here, we review how tetraploidy can occur and describe the cellular responses to increased ploidy. Furthermore, we discuss how the specific physiological changes that are triggered by polyploidization might be …

网页2014年11月19日 · Tetraploidy generally arises as a result of three different pathways: endoreduplication, in which the genome is re-replicated without an intervening mitosis; cell fusion, which is often instigated by viral infections; and cytokinesis/mitotic failure.
