Genome-wide Association Studies-GWAS01:11

Genome-wide Association Studies-GWAS

15.3K
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...

Autoimmune Disorders01:29

Autoimmune Disorders

1.5K
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

12.2K
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...

Nephrotic Syndrome I : Introduction

510
Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of...

Rheumatic Heart Disease I: Introduction

448
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...

Atherosclerosis III: Management

322
Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...

Area of Science:

  • Immunology
  • Molecular Biology
  • Genetics

Background:

  • Systemic lupus erythematosus (SLE) is a complex autoimmune disease impacting multiple organs.
  • SLE is characterized by autoantibody production, elevated type-I cytokines, and potential glomerulonephritis.
  • The precise causes of SLE remain largely unknown.

Purpose of the Study:

  • To investigate the association between the DNA-binding protein ARID3a and disease activity in SLE.
  • To identify potential therapeutic targets by examining ARID3a's role in SLE pathogenesis.
  • To explore ARID3a's expression patterns in various cell types relevant to SLE.

Main Methods:

  • Analysis of ARID3a expression in peripheral blood cells from SLE patients.
  • Comparison of gene expression patterns in SLE cells with high ARID3a versus healthy controls.
  • Examination of ARID3a expression in hematopoietic stem cells and kidney progenitor cells.

Main Results:

  • Increased ARID3a expression is strongly associated with higher disease activity in SLE patients.
  • ARID3a expression correlates with autoantibody production in B cells and interferon alpha in plasmacytoid dendritic cells and neutrophils.
  • SLE cells with elevated ARID3a exhibit distinct gene expression profiles, revealing potential regulatory pathways.

Conclusions:

  • ARID3a expression is linked to key features and increased severity of SLE.
  • ARID3a and its downstream targets represent promising avenues for novel SLE therapeutics.
  • Further research into ARID3a's regulatory functions could elucidate SLE pathogenesis.
