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

Area of Science:

• Biochemistry
• Molecular Biology
• Genetics

Background:

• Genomic DNA damage is a constant threat from internal and external factors.
• Proper DNA damage response (DDR) is crucial for genomic stability and cell function.
• Dysfunctional DDR can drive genomic instability and cancer development.

Purpose of the Study:

• To review how lipid metabolite-associated post-translational modifications (PTMs) regulate the DNA damage response (DDR).
• To explore the implications of these PTMs in tumorigenesis.
• To identify potential new targets for anti-cancer drug development.

Main Methods:

• Literature review focusing on recent advancements in mass spectrometry.
• Analysis of PTMs including acetylation, S-succinylation, N-myristoylation, palmitoylation, and crotonylation.
• Examination of the role of metabolites as PTM donors in DDR.

Main Results:

• Lipid metabolite-associated PTMs are key regulators of the DDR pathway.
• Specific PTMs like acetylation and crotonylation are implicated in DDR modulation.
• These modifications influence cellular responses to DNA damage, impacting cancer progression.

Conclusions:

• Lipid metabolite-associated PTMs represent a critical layer of DDR regulation.
• Understanding these modifications provides insights into cancer development.
• Targeting these PTMs holds promise for novel anti-cancer therapeutic strategies.
