RNA Stability01:53

RNA Stability

33.2K
Intact DNA strands can be found in fossils, while scientists sometimes struggle to keep RNA intact under laboratory conditions. The structural variations between RNA and DNA underlie the differences in their stability and longevity. Because DNA is double-stranded, it is inherently more stable. The single-stranded structure of RNA is less stable but also more flexible and can form weak internal bonds. Additionally, most RNAs in the cell are relatively short, while DNA can be up to 250 million...

Epigenetic Regulation

Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

Genome-wide Association Studies-GWAS

12.4K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

T Cell Types and Functions01:24

T Cell Types and Functions

945
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...

RNA Editing02:23

RNA Editing

8.9K
RNA editing is a post-transcriptional modification where a precursor mRNA (pre-mRNA) nucleotide sequence is changed by base insertion, deletion, or modification. The extent of RNA editing varies from a few hundred bases, in mitochondrial DNA of trypanosomes, to a just single base, in nuclear genes of mammals. Even a single base change in the pre-mRNA can convert a codon for one amino acid into the codon for another amino acid or a stop codon. This type of re-coding can significantly affect the...

Chromatin Structure Regulates pre-mRNA Processing02:41

Chromatin Structure Regulates pre-mRNA Processing

6.9K
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.
The chromatin structure, especially...

Area of Science:

  • Rheumatology
  • Immunology
  • Epigenetics

Background:

  • Rheumatoid arthritis (RA) is a progressive autoimmune condition causing joint damage and disability.
  • RA pathogenesis involves complex interactions between fibroblast-like synoviocytes (FLSs) and immune cells, driving chronic inflammation.
  • Epigenetic modifications are increasingly recognized for their role in RA development and progression.

Purpose of the Study:

  • To review current evidence on the involvement of DNA and RNA methylation in rheumatoid arthritis.
  • To highlight the significance of epigenetic alterations as potential biomarkers for RA diagnosis and treatment.
  • To explore the role of epigenetic regulators in controlling gene expression within the context of RA-associated inflammation.

Main Methods:

  • Literature review of recent studies on epigenetics in rheumatoid arthritis.
  • Analysis of research focusing on DNA methylation patterns in RA.
  • Examination of studies investigating RNA methylation alterations in RA pathogenesis.

Main Results:

  • Epigenetic alterations, particularly DNA and RNA methylation, are implicated in the complex pathogenesis of RA.
  • These epigenetic changes influence the expression of pro-inflammatory factors and immune cell interactions.
  • Evidence suggests epigenetic modifications could serve as valuable biomarkers for RA.

Conclusions:

  • DNA and RNA methylation are critical epigenetic mechanisms involved in rheumatoid arthritis.
  • Targeting epigenetic pathways may offer novel therapeutic strategies for RA.
  • Further research into epigenetic regulators is essential for advancing RA understanding and management.
