# The Potential Role of Deubiquitinating Enzymes (DUBs) in Male Fertility

## TL;DR

This paper reviews how deubiquitinating enzymes (DUBs) may influence male fertility by regulating the process of sperm production.

## Contribution

The paper summarizes recent findings on the role of DUBs in spermatogenesis and their potential as therapeutic targets for male infertility.

## Key findings

- Loss-of-function mouse models show DUBs are involved in spermatogenesis.
- Genetic variants in DUB genes are linked to spermatogenic failure and male infertility.
- DUBs are essential for normal spermatogenesis, but their exact mechanisms remain unclear.

## Abstract

Ubiquitination dynamically regulates critical cellular processes, including cell cycle progression, apoptosis, DNA repair, and chromatin remodeling. Deubiquitinating enzymes (DUBs) negatively regulate protein ubiquitination and are equally important for protein regulation in diverse biological processes. Spermatogenesis is a highly regulated process involving spermatogonia self-renewal and differentiation, ensuring continuous sperm production. Using a loss-of-function mouse model, several DUBs have been shown to be involved in spermatogenesis. In addition, specific genetic variants in the DUB genes have been associated with spermatogenic failure and male infertility. These studies provide strong evidence that DUBs are necessary for normal spermatogenesis and may influence male fertility. However, the exact mechanism by which these DUBs regulate spermatogenesis is still under investigation. The aim of this review is to highlight recent advances in the regulatory roles of DUBs in mammalian spermatogenesis and provide insight into the molecular mechanisms underlying their potential actions. An in-depth understanding of DUB-mediated regulation of spermatogenesis will provide a scientific rationale for the discovery and development of novel DUB-targeted therapeutic strategies for male infertility.
