Advances on the metabolism of cohesin in age-related chromosomal aneuploidy

Age-related chromosomal aneuploidy is associated with the reduction of cohesin in meiosis. There are many complicated factors affecting the metabolism of cohesion, including the hyperactive separase, abnormal Shugoshin protein degradation, oxidative damage, increased intracellular pH in oocytes, abnormal metabolism of spindle assembly checkpoint, anaphase-promoting complex, and age-related reproductive hormones, which are summarized in the review.
