Sirtuin Functions in Female Fertility: Possible Role in Oxidative Stress and Aging

Abstract EN

In search for strategies aimed at preventing oxidative threat to female fertility, a possible role of sirtuins has emerged.

Sirtuins (silent information regulator 2 (Sir2) proteins), NAD+ dependent enzymes with deacetylase and/or mono-ADP-ribosyltransferase activity, are emerging as key antiaging molecules and regulators in many diseases.

Recently, a crucial role for SIRT1 and SIRT3, the main components of sirtuin family, as sensors and guardians of the redox state in oocytes, granulosa cells, and early embryos has emerged.

In this context, the aim of the present review is to summarize current knowledge from research papers on the role of sirtuins in female fertility with particular emphasis on the impairment of SIRT1 signalling with oocyte aging.

On this basis, the authors wish to build up a framework to promote research on the possible role of sirtuins as targets for future strategies for female fertility preservation.
