Loss of the Y chromosome in aging men is widespread and increasingly linked to serious diseases, challenging assumptions that ...

Men tend to lose the Y chromosome from their cells as they age. But because the Y bears few genes other than for male determination, it was thought this loss would not affect health. But evidence has ...

Two new studies of the evolutionary history of the Y chromosome show that, contrary to popular (if not scientific) belief, the male is not at risk of dying out. The Y chromosome which, among other ...

Eighty percent of patients with autoimmune diseases are female. These diseases are one of the top 10 leading causes of death for women under 65, and cases are increasing annually worldwide. There is ...

Scientists have discovered a new property of the molecular motors that shape our chromosomes. While six years ago they found that these so-called SMC motor proteins make long loops in our DNA, they ...

A hitherto unknown mechanism for DNA folding is described in a new study. The findings provide new insights into chromosomal processes that are vital to both normal development and to prevent disease.

As men age, many quietly lose the Y chromosome in some cells, and scientists now link this hidden change to heart disease, cancer and even shorter lifespans.

Robertsonian chromosomes are large chromosomes that form when the long arm of a chromosome breaks and fuses with another chromosome. They are the most common type of chromosome rearrangement in humans ...

A picture of a mouse MII stage eggs with the location of chromosomes (green) and the distribution of the histone modification H3K4me3 (purple). The team confirmed that H3K4me3 was significantly ...
