Deacetylation of nonhistone proteins by HDACs and the implications in cancer
1H. Lee Moffitt Cancer Center and Research Institute, Tampa, FL 33612, USA.
Abstract:
Acetylation and deacetylation of lysine residues controlled by histone acetyltransferases (HATs) and histone deacetylases (HDACs), respectively, are among the most common posttranslational modifications of proteins. In addition to histones, a large number of nonhistone proteins that can undergo reversible acetylation have been identified. These nonhistone acetylated/deacetylated proteins are involved in a wide range of cellular processes including transcription, translation, DNA repair, metabolism, and cell structure. Aberrant deacetylation of nonhistone proteins is implicated in many human diseases, including cancer. In this chapter, we review and describe the involvement of HDACs in cancer-associated cellular processes via deacetylation of nonhistone proteins, and the possible implications for carcinogenesis and cancer development.
Insights
Histone deacetylases (HDACs) regulate protein acetylation, a key modification. Aberrant HDAC activity in nonhistone proteins drives cancer development by affecting cellular processes.
Area of Science:
- Biochemistry
- Molecular Biology
- Oncology
Background:
- Protein acetylation and deacetylation are crucial posttranslational modifications.
- Histone acetyltransferases (HATs) and histone deacetylases (HDACs) control these processes.
- Nonhistone proteins, beyond histones, are also subject to acetylation, impacting diverse cellular functions.
Purpose of the Study:
- To review the role of HDACs in cancer.
- To describe how HDACs deacetylate nonhistone proteins.
- To explore the implications for carcinogenesis and cancer development.
Main Methods:
- Literature review of studies on HDACs and nonhistone protein acetylation.
- Analysis of cellular processes affected by nonhistone protein deacetylation.
- Examination of the link between aberrant deacetylation and human diseases, particularly cancer.
Main Results:
- Nonhistone protein deacetylation by HDACs is implicated in various cellular processes.
- Dysregulated deacetylation of nonhistone proteins is linked to human diseases, including cancer.
- HDACs play a significant role in cancer-associated cellular functions.
Conclusions:
- HDACs' involvement in deacetylation of nonhistone proteins contributes to cancer development.
- Targeting HDACs may offer therapeutic strategies for cancer treatment.
- Understanding nonhistone protein acetylation is vital for cancer research.
