Silent X chromosome awakens with age: New explanation for sex differences in age-related diseases

Women age differently from men when it comes to health—particularly in conditions like cardiovascular disease and neurodegenerative disorders such as dementia and Parkinson's.

Technical University of Munich Researchers Discover Mechanism Behind Female-Specific Aging Health Conditions

Technical University of Munich Researchers Discover Mechanism Behind Female-Specific Aging Health Conditions (IN BRIEF) A team at the Technical University of Munich has uncovered a potential new explanation for sex-based differences in age-related diseases. Their study found that as female mice age, genes on the silenced second X chromosome become active again. This reactivation could play a role in both the positive and negative health effects …

In old age, the second X chromosome becomes partially active in women. New findings show possible consequences for health and disease progression.

Researchers at the Technical University of Munich have discovered a new mechanism that could explain gender differences in age-related diseases. As TUM announced on Tuesday, genes on the normally inactive second X chromosome become reactivated in female mice as they age. This process could also play a role in women. Women have two X chromosomes, one of which is normally inactive. The study shows that in older animals, up to nine percent of the g…
