Aneuploidy tolerance caused by BRG1 loss allows chromosome gains and recovery of fitness
Nature Communications, 2022 Aneuploidy results in decreased cellular fitness in many species and model systems. However, aneuploidy is commonly found in cancer cells and often correlates with aggressive growth, suggesting that the impact of aneuploidy on cellular fitness is context

Fertility & Reproduction, 2023 Background and Aims: Maternal age has been reported to impact on embryo genetic status. However, current data on the association between maternal age and early embryo development are limited and inconclusive, especially among good-prognosis women.

BMC Pregnancy and Childbirth, 2023 Background To compare the aneuploidy rate in spontaneous abortion chorionic villus (SA-CV) after D5 and D6 thawed-frozen blastocyst transfer(TBT). Methods This retrospective cohort study recruited 522 patients with early spontaneous abortion from March ...

Fertility & Reproduction, 2023 Background and Aims: Embryo aneuploidy is caused by many factors, including patient age, sperm quality and sperm selection method. There are several methods for selecting sperm, ICSI (intracytoplasmic sperm injection) and IMSI (intracytoplasmic ...

Quantitative proteomic analysis reveals posttranslational responses to aneuploidy in yeast
eLife, 2014 Aneuploidy causes severe developmental defects and is a near universal feature of tumor cells. Despite its profound effects, the cellular processes affected by aneuploidy are not well characterized. Here, we examined the consequences of aneuploidy on the

Aneuploidy: Tolerating Tolerance [PDF]
Current Biology, 2015 Individuals, and cells, vary in their ability to tolerate aneuploidy, an unbalanced chromosome complement. Tolerance mechanisms can be karyotype-specific or general. General tolerance mechanisms may allow cells to benefit from the phenotypic plasticity conferred by access to multiple aneuploid states.

BMC Pregnancy and Childbirth, 2023 Background Aneuploidy pregnancy is a severe major birth defect and causes about 50% spontaneous miscarriages with unknown etiology. To date, only a few epidemiological studies with small sample sizes have investigated the risk factors for aneuploidy ...

Consequences of Chromosome Loss: Why Do Cells Need Each Chromosome Twice?
Cells, 2022 Aneuploidy is a cellular state with an unbalanced chromosome number that deviates from the usual euploid status. During evolution, elaborate cellular mechanisms have evolved to maintain the correct chromosome content over generations.

Dosage compensation can buffer copy-number variation in wild yeast
eLife, 2015 Aneuploidy is linked to myriad diseases but also facilitates organismal evolution. It remains unclear how cells overcome the deleterious effects of aneuploidy until new phenotypes evolve. Although laboratory strains are extremely sensitive to aneuploidy,

From tumorigenesis to cell death: the aneuploidy paradox
Molecular & Cellular Oncology, 2020 Aneuploidy, an abnormal chromosome number, is a hallmark of cancer. We recently showed that depletion of microtubule-associated protein ATIP3 (AT2 receptor-interacting protein 3) induces aneuploidy and sensitizes breast cancer cells to taxanes. Combining
