lncRNA - Long Non-coding RNAs02:39

lncRNA - Long Non-coding RNAs

10.0K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

Types of RNA

10.0K
Three main types of RNA are involved in protein synthesis: messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). These RNAs perform diverse functions and can be broadly classified as protein-coding or non-coding RNA. Non-coding RNAs play important roles in regulating gene expression in response to developmental and environmental changes. Non-coding RNAs in prokaryotes can be manipulated to develop more effective antibacterial drugs for human or animal use.

T Cell Types and Functions01:24

T Cell Types and Functions

2.7K
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...

Genome-wide Association Studies-GWAS

15.8K
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...

Summary

Long non-coding RNAs (lncRNAs) show altered expression in rheumatoid arthritis, acting as potential biomarkers for diagnosis and therapeutic targets. Specific circulating lncRNAs, like HOTAIR, can distinguish patients from healthy individuals.

Area of Science:

  • Immunology
  • Molecular Biology
  • Genetics

Background:

  • Rheumatoid arthritis (RA) is an autoimmune disease characterized by altered gene expression in immune cells and synovial tissues.
  • Long non-coding RNAs (lncRNAs) are emerging as key regulators of immune and inflammatory pathways.
  • Dysregulation of lncRNAs is implicated in RA and other autoimmune conditions.

Purpose of the Study:

  • To explore the role of lncRNAs as potential biomarkers and therapeutic targets in rheumatoid arthritis.
  • To investigate the association between lncRNA expression and RA pathogenesis.
  • To evaluate the diagnostic potential of circulating lncRNAs in RA.

Main Methods:

  • Analysis of gene expression in circulating immune cells and synovial tissues from RA patients and healthy controls.
  • Review of experimental studies investigating lncRNA function in autoimmune and inflammatory pathways.
  • Assessment of specific circulating lncRNAs, such as HOTAIR, for their ability to differentiate RA patients.

Main Results:

  • lncRNAs are dysregulated in rheumatoid arthritis and play roles in immune and inflammatory processes.
  • lncRNAs interact with key pathways like NF-κB signaling and T-cell responses relevant to autoimmunity.
  • Circulating lncRNA HOTAIR demonstrated potential in distinguishing RA patients from healthy subjects.

Conclusions:

  • lncRNAs represent promising biomarkers for rheumatoid arthritis diagnosis and prognostication.
  • lncRNAs are viable therapeutic targets for managing rheumatoid arthritis.
  • Further research on in vivo delivery and clinical validation of lncRNAs is warranted for RA treatment.
