Cancer cells are aneuploid
; they have an incorrect number of chromosomes.
CONCLUSIONS: Benzene appeared to increase the frequencies of aneuploid
sperm for chromosomes associated with chromosomal abnormality syndromes in human offspring, even in men whose air benzene exposure was at or below the U.S.
exhibits a particularly exceptional aneuploid
series, ranging from n=6 to n=66 (Tanaka, 1949), with every number from n=6 to n=47 represented by at least one species (Roalson et al., 2007).
These particulate chromate-induced aneuploid
cells were able to survive and form colonies (47,48).
CI might also favor the ability of cancer cells to acquire resistance to chemotherapics, such as the one related to imatinib mesylate, secondary to chromosome amplifications and duplications in cells with CI (Rajagopalan & Lengauer, 2004); and to 5-fluorouracyl, resulting from amplification of the thymidylate synthetase gene in aneuploid
cells (Wang et al., 2004).
After discarding the haploid, tetraploid, and a few aneuploid
plants, which did not set seeds or exhibited very low spikelet fertility, the 325 normal seed setting plants (DH) were harvested.
These studies demonstrated that AD strains were diploid or aneuploid
hybrids derived from a fusion of serotype A and D parents and that several of them were harboring a serotype A MATa locus.
Several mechanisms of aneuploid
decrease or increase are well documented in angiosperm evolution, including descending and ascending dysploidy, nullisomy, and tetrasomy (Stebbins 1950; Darlington 1973; White 1978; Stace 1980; Grant 1981).
Over time, the aneuploid
peak in TD crosses split into two peaks: one close to 2 n and the other close to 3 n.
Ploidy analysis revealed 12.5% tetraploid, with 0% aneuploid
or hyperploid cells; 8.5% of the cells were in S phase and 21% in the proliferative phase.
These techniques have been designed for a variety of purposes, including identification of embryos affected or carriers of monogenic diseases, identification of aneuploid
embryos or selection of embryos with specific gender.
In patients with POR, the incidence of aneuploid
blastocysts is higher, with 35.1% of all aneuploid
blastocyst cycles reported .
