Aneuploidy in Early Miscarriage and its Related Factors

open access: yesChinese Medical Journal, 2015
Background: Genetic factors are the main cause of early miscarriage. This study aimed to investigate aneuploidy in spontaneous abortion by fluorescence in situ hybridization (FISH) using probes for 13, 16, 18, 21, 22, X and Y chromosomes.

Short- and long-term effects of chromosome mis-segregation and aneuploidy [PDF]

open access: yes, 2015
Dividing cells that experience chromosome mis-segregation generate aneuploid daughter cells, which contain an incorrect number of chromosomes. Although aneuploidy interferes with the proliferation of untransformed cells, it is also, paradoxically, a ...

Protein turnover downstream of the Nipbl/CRL4 axis contributes to abnormal development in zebrafish embryos

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Mutations in cohesins cause cohesinopathies such as Cornelia de Lange Syndrome (CdLS) and Roberts Syndrome (RBS). Prior findings demonstrate that Esco2 (a cohesin activator) and Smc3 (a core cohesin subunit) regulate the CRL4 E3 ubiquitin ligase. SMC3 mutations, however, account for a small percentage of CdLS.

Interpretation of in vitro concentration‐response data for risk assessment and regulatory decision‐making: Report from the 2022 IWGT quantitative analysis expert working group meeting

open access: yesEnvironmental and Molecular Mutagenesis, EarlyView.
Abstract Quantitative risk assessments of chemicals are routinely performed using in vivo data from rodents; however, there is growing recognition that non‐animal approaches can be human‐relevant alternatives. There is an urgent need to build confidence in non‐animal alternatives given the international support to reduce the use of animals in toxicity ...

LSD1 is essential for oocyte meiotic progression by regulating CDC25B expression in mice [PDF]

open access: yes, 2015
Mammalian oocytes are arrested at prophase I until puberty when hormonal signals induce the resumption of meiosis I and progression to meiosis II.

Evaluation of the standard battery of in vitro genotoxicity tests to predict in vivo genotoxicity through mathematical modeling: A report from the 8th International Workshop on Genotoxicity Testing

open access: yesEnvironmental and Molecular Mutagenesis, EarlyView.
Abstract In human health risk assessment of chemicals and pharmaceuticals, identification of genotoxicity hazard usually starts with a standard battery of in vitro genotoxicity tests, which is needed to cover all genotoxicity endpoints. The individual tests included in the battery are not designed to pick up all endpoints.

Aneuploidy Drives Genomic Instability in Yeast [PDF]

open access: yes, 2011
Aneuploidy decreases cellular fitness, yet it is also associated with cancer, a disease of enhanced proliferative capacity. To investigate one mechanism by which aneuploidy could contribute to tumorigenesis, we examined the effects of aneuploidy on ...

Critical Evaluation of Methods for the Identification of Aneugens

open access: yesEnvironmental and Molecular Mutagenesis, EarlyView.
ABSTRACT The genotoxic potential of chemicals must be evaluated in regulatory safety assessment settings, including but not limited to, the development of new pharmaceuticals, industrial chemicals, food and cosmetic ingredients, and agrochemicals. Initial assessment of the chromosome‐damaging potential of chemicals is often conducted in mammalian cells

Chromosomal disorders and male infertility [PDF]

open access: yes, 2011
Infertility in humans is surprisingly common occurring in approximately 15% of the population wishing to start a family. Despite this, the molecular and genetic factors underlying the cause of infertility remain largely undiscovered.

Application of a Saliva‐Based Liquid Biopsy for the Detection of HPV in Patients With Oral Cavity Squamous Cell Carcinoma (OCSCC)

open access: yesHead &Neck, EarlyView.
ABSTRACT Background Human papilloma virus (HPV) is a DNA virus capable of infecting mucous membranes. In most cases, the infection is cleared by the immune system, but a prolonged exposure to HPV can progress to cancer. 40%–60% of head and neck squamous cell carcinomas (HNSCC) are linked to HPV, which is considered a risk factor especially among young ...
