Researchers at the Francis Crick Institute studying male mice engineered with different Y chromosome deletions have uncovered which genes on the mouse Y chromosome regulate the development of sperm ...

One of the most detailed 3D maps of how the human chromosomes are organized and folded within a cell's nucleus is published ...

Researchers at the Crick have uncovered which genes on the Y chromosome regulate the development of sperm and impact fertility in male mice. This research could help us understand why some men don't ...

Doctors in Brazil discover and confirm that a woman has blood with male chromosomes, a rare case of human chimerism.

The silencing of the one X chromosome in XX cells is mediated by XIST, a long noncoding RNA that is randomly transcribed from only one X early in development. It coats the DNA and shuts down gene ...

University of Virginia School of Medicine researchers have discovered a gene on the Y chromosome that contributes to the greater incidence of heart failure in men. Y chromosome loss in men occurs ...
