Aging Promotes Reactivation of the Barr Body at Distal Chromosome Regions

1. Academic Background: The Mysterious Link between X Chromosome Inactivation and Aging In mammals, females possess two X chromosomes while males have only one. To maintain gene dosage balance between the sexes, females undergo a process called X chromosome inactivation (XCI) early in development, in which one of the two X chromosomes is randomly s...

Aberrant Engagement of P-selectin Drives Hematopoietic Stem Cell Aging in Mice

1. Research Background and Scientific Problem The health of the hematopoietic system is crucial to the proper functioning of the body, with hematopoietic stem cells (HSCs) at its core in maintaining normal blood system operation. HSCs possess self-renewal and multipotent differentiation abilities, capable of generating all types of blood cells, inc...
