Editorial: Epigenetic Aging in Oocytes

“In summary, our group demonstrates basic principles in the early aging of mammalian oocytes.”

BUFFALO, NY- August 30, 2023 – A new editorial paper was published in Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 15, Issue 15, entitled, “Epigenetic aging in oocytes.”

Aging-related phenotypes span many different tissues and cell types, and start to occur at different ages - a different typical age for every cell type. In their new editorial, researchers Peera Wasserzug-Pash and Michael Klutstein from The Hebrew University of Jerusalem discuss one of the earliest occurring aging events in the human body, which is the beginning of female reproductive aging and deterioration. The clinical cut-off for advanced maternal age (AMA), a condition associated with poor reproductive outcomes, is 35 years old. 

“The early onset of reproductive aging poses a significant challenge to clinicians since a global consistent increase in maternal age at first birth has occurred in recent decades, effectively shortening the available time window for reproduction [1].”

As the rate of patients with advanced maternal age rises, and with it, the number of patients in fertility clinics, so does the necessity for a fundamental understanding of the reproductive aging process. In recent years, it has been established that there is a substantial dominating influence of oocyte quality loss on age-related fertility decline. This is best demonstrated by the rise in IVF success rates in reproductively aged women when they receive an egg donation from a younger woman. Oocyte quality loss is characterized by diminished cellular function and an increased occurrence of chromosomal nondisjunctions. 

“Our recent publication [4] addresses the question of additional, epigenetic mechanisms that lead to the occurrence of age-related oocyte quality loss.”

About Aging-US:

The mission of the journal is to understand the mechanisms surrounding aging and age-related diseases, including cancer as the main cause of death in the modern aged population.

The journal aims to promote 1) treatment of age-related diseases by slowing down aging, 2) validation of anti-aging drugs by treating age-related diseases, and 3) prevention of cancer by inhibiting aging. (Cancer and COVID-19 are age-related diseases.)
