As a group, women may be more likely than men to develop Alzheimer’s disease, but once they have it, they cope better and live longer. A study published August 26 in Science Translational Medicine ...

Autoimmune diseases tend to strike women more than men and having multiple X chromosomes could be the main reason why. While a process called X chromosome inactivation serves to balance out gene ...

For a person with two X chromosomes, full expression of the genes on both could mean a disastrous double dose of their protein products, interfering with the delicate balance of protein expression and ...

Research shows synthetic chromosomes can be transferred to human cells with potential to improve viral resistance ...

Women live longer than men with Alzheimer's because their sex chromosomes give them genetic protection from the ravages of the disease. Women get two 'doses' of a gene that only exists on the X ...

A laboratory population of D. melanogaster was begun with initial frequencies of the second chromosome inversions as follows: 70% standard, 25% In(2L)B and 5% In(2R)C. In(2R)C was eliminated from this ...

Chromosomes are thread-like structures comprising DNA that are present inside the nucleus of every cell in the body. Specific segments of DNA are called genes. Every chromosome contains many genes, ...

Medical researchers describe how X chromosome inactivation is regulated in the immune system's B cells as they develop in bone marrow and when they encounter antigens. Autoimmune diseases tend to ...
