Current Biology, 2015 The terms 'haploid' and 'diploid' that describe single (n) and double (2n) chromosome sets in cells were coined by the Polish-German botanist Eduard Strasburger and originate from the Greek terms haplóos meaning 'single' and diplóos meaning 'double'.

Stem-Like Adaptive Aneuploidy and Cancer Quasispecies [PDF]
, 2013 We analyze and reinterpret experimental evidence from the literature to argue for an ability of tumor cells to self-regulate their aneuploidy rate. We conjecture that this ability is mediated by a diversification factor that exploits molecular mechanisms

Aneuploidy and proteotoxic stress in cancer [PDF]
, 2015 Although nearly ubiquitous in cancer, aneuploidy exerts detrimental effects on human cells. We recently demonstrated that aneuploid human cells exhibit impaired heat shock factor protein 1 (HSF1) and HSP90 function, suggesting a functional link between ...

Fluconazole Monotherapy Is a Suboptimal Option for Initial Treatment of Cryptococcal Meningitis Because of Emergence of Resistance. [PDF]
, 2019 Cryptococcal meningitis is a lethal disease with few therapeutic options. Induction therapy with fluconazole has been consistently demonstrated to be associated with suboptimal microbiological and clinical outcomes. Exposure to fluconazole causes dynamic

FoxM1 repression during human aging leads to mitotic decline and aneuploidy-driven full senescence
Nature Communications, 2018 Evidence for mitotic decline in aged cells and for aneuploidy-driven progression into full senescence is limited. Here, the authors find that in aged cells, mitotic gene repression leads to increased chromosome mis-segregation and aneuploidy that ...

Actomyosin drives cancer cell nuclear dysmorphia and threatens genome stability
Nature Communications, 2017 Recent findings suggest that forces acting on the cell nucleus can cause DNA damage, but the mechanisms are unclear. Here Takakiet al. report that actomyosin is a determinant of nuclear shape and that unrestrained contractility elicits nuclear envelope ...

Ectopic expression of human TUBB8 leads to increased aneuploidy in mouse oocytes
Cell Discovery, 2023 Aneuploidy seriously compromises female fertility and increases incidence of birth defects. Rates of aneuploidy in human eggs from even young women are significantly higher than those in other mammals.

DNA double strand breaks but not interstrand crosslinks prevent progress through meiosis in fully grown mouse oocytes [PDF]
, 2012 There is some interest in how mammalian oocytes respond to different types of DNA damage because of the increasing expectation of fertility preservation in women undergoing chemotherapy.

mBio, 2017 Aneuploidy is usually deleterious in multicellular organisms but appears to be tolerated and potentially beneficial in unicellular organisms, including pathogens. Leishmania, a major protozoan parasite, is emerging as a new model for aneuploidy, since in
