Summary
ATP-dependent chromatin remodelers influence blood pressure regulation. Research suggests these remodelers may be key targets for novel hypertension therapeutics, offering new hope for treating this widespread cardiovascular disease.
Area of Science:
- Cardiovascular Science
- Molecular Biology
- Genetics
Background:
- Hypertension is a leading global cause of mortality and a major preventable risk factor for cardiovascular disease.
- Despite progress, the exact causes of hypertension remain unclear, necessitating innovative therapeutic strategies.
- ATP-dependent chromatin remodelers regulate gene expression by altering DNA-histone bonds.
Purpose of the Study:
- To review and summarize the role of ATP-dependent chromatin remodelers in the development and maintenance of hypertension.
- To explore emerging evidence linking chromatin remodelers to hypertension pathophysiology.
Main Methods:
- Review of existing literature on ATP-dependent chromatin remodelers and hypertension.
- Analysis of data from hypertensive animal models and human studies.
- Examination of genomic studies identifying mutations in chromatin remodeler genes in hypertensive patients.
Main Results:
- Animal models show increased chromatin remodeler activity elevates proinflammatory genes and blood pressure.
- Human studies indicate chromatin remodelers function as stress-response sensors.
- Genomic studies correlate hypertension with mutations in chromatin remodeler genes.
Conclusions:
- Evidence strongly links ATP-dependent chromatin remodelers to hypertension.
- Further research into chromatin remodelers could uncover novel therapeutic targets for hypertension.
- Understanding these mechanisms may lead to innovative treatments for this complex disease.

Nucleosome Remodeling
10.8K
Nucleosomes are the basic units of chromatin compaction. Each nucleosome consists of the DNA bound tightly around a histone core, which makes the DNA inaccessible to DNA binding proteins such as DNA polymerase and RNA polymerase. Hence, the fundamental problem is to ensure access to DNA when appropriate, despite the compact and protective chromatin structure.

ATP Yield
78.3K
Cellular respiration produces 30 - 32 ATP per glucose molecule. Although most of the ATP results from oxidative phosphorylation and the electron transport chain (ETC), 4 ATP are gained beforehand (2 from glycolysis and 2 from the citric acid cycle).
The ETC is embedded in the inner mitochondrial membrane and is comprised of four main protein complexes and an ATP synthase. NADH and FADH2 pass electrons to these complexes, which pump protons into the intermembrane space. This distribution of...

Chromatin Packaging
21.8K
Each human somatic cell contains 6 billion base-pairs of DNA. Each base-pair is 0.34 nm long, which means that each diploid cell contains a staggering 2 meters of DNA. How is such a long DNA strand packed inside a nucleus measuring only 10 - 20 microns in diameter?

Inheritance of Chromatin Structures
7.3K
Epigenetics is the study of inherited changes in a cell's phenotype without changing the DNA sequences. It provides a form of memory for the differential gene expression pattern to maintain cell lineage, position-effect variegation, dosage compensation, and maintenance of chromatin structures such as telomeres and centromeres. For example, the structure and location of the centromere on chromosomes are epigenetically inherited. Its functionality is not dictated or ensured by the underlying...

Spreading of Chromatin Modifications
9.3K
The histone proteins in the nucleosomes are post-translationally modified (PTM) to increase or decrease access to DNA. The commonly observed PTMs are methylation, acetylation, phosphorylation, and ubiquitination of lysine amino acids in the histone H3 tail region. These histone modifications have specific meaning for the cell. Hence, they are called "histone code". The protein complex involved in histone modification is termed as "reader-writer" complex.

Chromatin Structure Regulates pre-mRNA Processing
8.1K
In eukaryotic cells, nascent mRNA transcripts need to undergo many post-transcriptional modifications to reach the cell cytoplasm and translate into functional proteins. For a long time, transcription and pre-mRNA processing were considered two independent events that occur sequentially in the cell. However, it has now been well established that transcription and pre-mRNA processing are two simultaneous processes that are precisely regulated inside the cell.
