Genome-wide Association Studies-GWAS01:11

Genome-wide Association Studies-GWAS

14.5K
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

1.4K
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...

The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

9.3K
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...

Rheumatic Heart Disease I: Introduction

57
Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

Rheumatic Heart Disease III: Medical Management

Rheumatic heart disease (RHD) management can be divided into two main strategies: prevention and long-term management.Primary PreventionPrimary prevention focuses on timely diagnosis and management of group A streptococcal pharyngitis to prevent acute rheumatic fever. The most widely used antibiotic for treating this condition is intramuscular benzathine penicillin G.Acute Rheumatic Fever TreatmentThe primary treatment goal for a patient diagnosed with acute rheumatic fever is to suppress the...

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies

81
The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...

Area of Science:

  • Biochemistry and Molecular Biology
  • Immunology and Rheumatology

Background:

  • Small ubiquitin-like modifier (SUMO) proteins undergo reversible covalent and non-covalent attachment to lysine residues on substrates.
  • SUMOylation and de-SUMOylation processes maintain cellular homeostasis, regulated by SUMO pathway components.
  • Dysregulation of SUMO components disrupts protein function and contributes to disease development.

Purpose of the Study:

  • To provide a systematic overview of SUMO component characteristics.
  • To summarize the impact of SUMO components on rheumatoid arthritis (RA) pathogenesis.
  • To highlight the potential of SUMO components as therapeutic targets for RA.

Main Methods:

  • Literature review and systematic analysis of SUMO component functions.
  • Examination of the role of specific SUMO components (SUMO-1, SUMO-2/3, SAE1/Uba2, Ubc9, PIASs, SENPs) in RA.
  • Review of studies on single nucleotide polymorphisms (SNPs) in SUMO components and their association with RA susceptibility.

Main Results:

  • Several SUMO components are implicated in the pathogenesis of RA.
  • SUMO pathway dysregulation alters target protein functions, contributing to RA.
  • Single nucleotide polymorphisms (SNPs) in SUMO components, such as SUMO-4, are associated with RA susceptibility.

Conclusions:

  • SUMOylation pathway components play a significant role in RA.
  • Targeting SUMO components offers potential therapeutic strategies for RA.
  • Further research into SUMO component genetics and function in RA is warranted.
