Experimental Insights into the Interplay between Histone Modifiers and p53 in Regulating Gene Expression

Int J Mol Sci. 2023 Jul 3;24(13):11032. doi: 10.3390/ijms241311032.

Abstract

Chromatin structure plays a fundamental role in regulating gene expression, with histone modifiers shaping the structure of chromatin by adding or removing chemical changes to histone proteins. The p53 transcription factor controls gene expression, binds target genes, and regulates their activity. While p53 has been extensively studied in cancer research, specifically in relation to fundamental cellular processes, including gene transcription, apoptosis, and cell cycle progression, its association with histone modifiers has received limited attention. This review explores the interplay between histone modifiers and p53 in regulating gene expression. We discuss how histone modifications can influence how p53 binds to target genes and how this interplay can be disrupted in cancer cells. This review provides insights into the complex mechanisms underlying gene regulation and their implications for potential cancer therapy.

Keywords: cancer; chromatin structure; gene regulation; histone modifications; p53.
