Summary
Epigenetic factors like DNA methylation and non-coding RNAs are crucial in systemic sclerosis (SSc) pathogenesis. Understanding these epigenetic mechanisms, including exosomes and lncRNAs, offers potential biomarkers and therapeutic targets for SSc.
Area of Science:
- Immunology
- Genetics
- Molecular Biology
Background:
- Systemic sclerosis (SSc) is a rare, chronic autoimmune disease characterized by immune dysregulation, vascular damage, and fibrosis.
- The complex etiology of SSc involves genetic predisposition and environmental triggers.
- Epigenetic regulation is increasingly recognized as a key molecular mechanism influenced by environmental factors in SSc pathogenesis.
Purpose of the Study:
- To review current research on the role of epigenetics in systemic sclerosis.
- To explore specific epigenetic mechanisms, including DNA methylation, histone modification, and non-coding RNA regulation.
- To identify potential epigenetic biomarkers and therapeutic targets for SSc.
Main Methods:
- Literature review of recent advances in SSc epigenetics.
- Focus on key epigenetic regulators such as exosomes and long non-coding RNAs (lncRNAs).
- Analysis of studies investigating epigenetic alterations in SSc patients.
Main Results:
- Epigenetic modifications, including DNA methylation, histone modifications, and non-coding RNAs, significantly contribute to SSc development.
- Exosomes and lncRNAs are implicated as important mediators in SSc pathogenesis.
- Several epigenetic factors show promise as potential biomarkers for diagnosis and prognosis.
Conclusions:
- Epigenetic dysregulation is central to the pathogenesis of systemic sclerosis.
- Targeting epigenetic mechanisms, particularly exosome and lncRNA pathways, may offer novel therapeutic strategies for SSc.
- Further research into epigenetic biomarkers could improve SSc management.

01:37Epigenetic Regulation
3.2K
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

01:32Chromatin Modification in iPS Cells
1.9K
Chromatin modification alters gene expression; therefore, scientists can add histone-modifying enzymes, histone variants, and chromatin remodeling complexes to somatic cells to aid reprogramming into pluripotent stem (iPS) cells.
Compact chromatin makes reprogramming difficult. Enzymes, such as histone demethylases and acetyltransferases, are often added during reprogramming to loosen the chromatin, making the DNA more accessible to transcription factors. Molecules that inhibit histone...

01:20The JAK-STAT Signaling Pathway
9.4K
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...

01:23Cystic Fibrosis: Pathogenesis
382
Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

02:30Genomic Imprinting and Inheritance
35.4K
Diploid organisms inherit genetic material through chromosomes from both parents. Copies of the same gene are known as alleles. In most cases, both alleles are simultaneously expressed and allow various cellular processes to function optimally. If one of the alleles is missing or mutated, the expression of the other allele can compensate; however, this is not true for all genes.
The expression of some genes depends on which parent passed the gene to the offspring, through a phenomenon known as...

02:32Histone Modification
14.3K
The histone proteins have a flexible N-terminal tail extending out from the nucleosome. These histone tails are often subjected to post-translational modifications such as acetylation, methylation, phosphorylation, and ubiquitination. Particular combinations of these modifications form “histone codes” that influence the chromatin folding and tissue-specific gene expression.
