X-chromosome inactivation varies across different areas of brains. Here, fluorescent imaging data from a mouse reveal where the father’s X chromosome is most active (white) and least active (blue). A ...

Shaped by thousands of years of evolution, the body’s immune system is a vigilant guardian primed against external infectious threats. Too much vigilance, however, and this guardian of potent cells ...

The reason female brains have less cognitive aging may be due to the reawakening of the dormant X chromosome late in life, which turns on genes that help sustain healthy brain cell connections. This ...

Maternal genetics have an outsized role to play, as they shape body's response to stress, ability to fight with infections ...

In a surprise, work in mice has found that the dormant X chromosome in females can reawaken late in life and turn on genes that keep the brain healthy. UCSF researchers may have discovered how the ...

Researchers from the University of California, San Francisco (UCSF) say they have now found that when the brain cells of female mice express only a maternal X chromosome, the animals’ memory and ...

Each human cell contains 23 pairs of chromosomes that carry DNA within their nucleus. The X and Y chromosomes, commonly referred to as the sex chromosomes, are one such pair. They determine the ...
