People who have one of several well-documented medical conditions do not have only XX or XY chromosomes, which typically correspond with female and male sexes, respectively. Those conditions include ...

A new study reveals that the maternal X chromosome may accelerate brain ageing and increase Alzheimer's risk. Experiments on female lab mice showed that older mice with only the maternal X ...

The X chromosome passed from mom to offspring may accelerate brain aging, a new animal study suggests. The research highlights a potential fundamental difference in how males' and females' brains age.

Gene editing techniques may eventually allow trisomy to be treated at the cellular level, according to an in vitro proof-of-concept study. Down syndrome is caused by the presence of a third copy ...

A study from the University of California San Francisco reveals that women’s cognitive abilities and brain aging may be influenced by whether they’re primarily using the X chromosome inherited ...

3 in the journal Current Biology ... but not a whole chromosome. Even in humans, the X/Y sex chromosome system isn't as clear-cut as it might look on paper; gene mutations or inheriting extra ...

Ordinarily we have 46 chromosomes, 23 from our mother and 23 from our father. Of these, 44 are autosomes and 2 are sex chromosomes. A person's sex is determined by the X and Y chromosomes with males ...

The manuscript addresses the 3D chromatin architecture in monocytes from patients with alcohol-associated hepatitis and its relationship to enhanced transcription of innate immune genes. While the ...

Mouse embryonic fibroblasts (MEFs) were used for mitotic chromosome measurements. The MEF cells were cultured in DMEM (Corning) supplemented with 10% fetal bovine serum (FBS) (HyClone) and 1% ...

“This is just showing one more interesting thing about them: They have really ancient sex chromosomes.” Most mammals know that females have 2 X chromosomes while males will have an XY pai ...

University of Oregon researchers have identified a sex chromosome in the California two-spot octopus. This chromosome has likely been around for 480 million years, since before octopuses split apart ...

The nucleus of every human cell contains chromosomes—23 pairs, to be exact. These carry our genetic material, known as the genome, and are composed of deoxyribonucleic acid (DNA) and proteins.
