Post-Translational Modifications by Lipid Metabolites during the DNA Damage Response and Their Role in Cancer

Biomolecules. 2022 Nov 8;12(11):1655. doi: 10.3390/biom12111655.

Abstract

Genomic DNA damage occurs as an inevitable consequence of exposure to harmful exogenous and endogenous agents. Therefore, the effective sensing and repair of DNA damage are essential for maintaining genomic stability and cellular homeostasis. Inappropriate responses to DNA damage can lead to genomic instability and, ultimately, cancer. Protein post-translational modifications (PTMs) are a key regulator of the DNA damage response (DDR), and recent progress in mass spectrometry analysis methods has revealed that a wide range of metabolites can serve as donors for PTMs. In this review, we will summarize how the DDR is regulated by lipid metabolite-associated PTMs, including acetylation, S-succinylation, N-myristoylation, palmitoylation, and crotonylation, and the implications for tumorigenesis. We will also discuss potential novel targets for anti-cancer drug development.

Keywords: DNA damage response; N-myristoylation; S-succinylation; acetylation; cancer; crotonylation; lipid metabolites; palmitoylation; post-translational modification.
