Pathophysiology of Diabetes01:20

Pathophysiology of Diabetes

953
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

DNA Microarrays02:34

DNA Microarrays

17.5K
Microarrays are high-throughput and relatively inexpensive assays that can be automated to analyze large quantities of data at a time. They are used in genome-wide studies to compare gene or protein expression under two varied conditions, such as healthy and diseased states. Microarrays consist of glass or silica slides on which probe molecules are covalently attached through surface functionalization. Most commonly, the slides are prepared through the chemisorption of silanes to silica...

The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

8.9K
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...

Psychoneuroimmunology: Diabetes and Cancer

31
Chronic stress has been linked to both the onset and progression of serious health conditions, including Type 2 diabetes and cancer. Type 2 diabetes, a widespread chronic illness, is closely associated with obesity and insulin resistance, both of which often worsen under stress. Studies indicate that men experiencing high levels of chronic stress face a 45% higher risk of developing diabetes compared to those with minimal stress. Stress triggers physiological responses that elevate blood...

Genome-wide Association Studies-GWAS01:11

Genome-wide Association Studies-GWAS

13.5K
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...

Diabetes Mellitus: Type 2 and Gestational01:22

Diabetes Mellitus: Type 2 and Gestational

2.5K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Area of Science:

  • Genomics and Bioinformatics
  • Dermatology
  • Endocrinology

Background:

  • Psoriasis and type 2 diabetes (T2D) are frequently comorbid.
  • The underlying molecular mechanisms connecting psoriasis and T2D remain largely unknown.

Purpose of the Study:

  • To elucidate the common molecular mechanisms and identify key genes and pathways involved in the pathogenesis of both psoriasis and T2D.

Main Methods:

  • Utilized gene expression data from Gene Expression Omnibus (GEO) for psoriasis (GSE30999) and T2D (GSE28829).
  • Identified common differentially expressed genes (DEGs) between the two conditions.
  • Performed functional enrichment analysis, protein-protein interaction (PPI) network analysis, and hub gene identification.

Main Results:

  • Identified 132 common DEGs (14 upregulated, 118 downregulated) between psoriasis and T2D.
  • Functional enrichment analysis highlighted the involvement of Rap1 signaling, PI3K-Akt signaling, and cGMP-PKG signaling pathways.
  • Identified three key hub genes: SNRPN, GNAS, and IGF2.

Conclusions:

  • Revealed potential common signaling pathways implicated in the pathogenesis of psoriasis and T2D.
  • The identified hub genes and pathways provide a basis for further research into the molecular links between these conditions.
