The above representative microscope images showcase ultra-fine bridges, a kind of abnormal link between chromosomes that causes catastrophic genetic instability. These bridges, composed of entangled ...

The current study shows that cells with additional chromosomes have an altered mitochondrial structure and function. The reason: mitochondrial precursor proteins are sequestered in p62-positive ...

DENVER -- Genetic testing and algorithms revealed that over 1% of more than 96,000 blastocyst-stage embryos had ploidy abnormalities, or atypical numbers of chromosomes. In total, ploidy abnormalities ...

Researchers created artificial kinetochore structures that reduce chromosome separation errors during meiosis in aging egg cells. By lowering microtubule pulling force, the approach helped maintain ...

For sexual reproduction to yield healthy offspring, newly generated oocytes—immature egg cells—must receive the correct amount of DNA after cell division. This process of segregating chromosomes ...

Nearly half the embryos studied underwent developmental arrest because of genetic mishaps in early development—a revealing insight that suggests more IVF babies could come to term with changes in the ...

Researchers have identified inherited genetic variants that may predict the loss of one copy of a woman's two X chromosomes as she ages, a phenomenon known as mosaic loss of chromosome X, or mLOX.

It has been known for several years that abnormal chromosome numbers lead to protein imbalances in the affected cells. Researchers at RPTU have now investigated the detailed effects of such imbalances ...
