Microtubules are critical components of the cytoskeleton that are extensively involved in various cellular and biological processes. The execution of these functions is intricately linked to post-translational modifications of tubulin. Post-translational modifications of tubulin include acetylation, tyrosination, de-tyrosination, glutamylation, SUMOylation, and so on. These modifications are closely associated with a wide range of biological processes. Accumulating evidence indicates that aberrant microtubule modifications are implicated in various diseases, including cancer, Alzheimer's disease, neurodevelopmental disorders, cardiac atrial hypertrophy, and even infertility. Aneuploid oocytes are a common cause of infertility, spontaneous abortion, trisomy syndrome, and other congenital abnormalities. The occurrence of aneuploidy is often closely associated with defects in spindle assembly, which are influenced by a series of tubulin modifications. In this review, we aimed to summarize the factors that affect tubulin modification and explore the key mechanisms underlying aneuploidy in human oocytes, thereby providing new insights and strategies for the treatment of infertility and prevention of congenital defects in newborns.
