Insights

The competitive endogenous RNA (ceRNA) network, specifically hsa_circ_0087100/hsa-miR-6743-5p/STAT1, influences Th1 cell differentiation in diabetic retinopathy (DR). This finding clarifies the role of ceRNA in DR immune infiltration.

Area of Science:

  • Immunology
  • Genetics
  • Ophthalmology

Background:

  • Diabetic retinopathy (DR) involves complex immune dysregulation.
  • The role of competitive endogenous RNA (ceRNA) networks in DR-associated immune infiltration remains unclear.

Purpose of the Study:

  • To investigate the function of the ceRNA network in immune cell infiltration within diabetic retinopathy.
  • To identify specific ceRNA pathways contributing to Th1 cell differentiation in DR.

Main Methods:

  • Utilized Gene Expression Omnibus data for differentially expressed circRNAs, miRNAs, and mRNAs.
  • Employed CIBERSORT and ssGSEA for immune infiltration analysis.
  • Conducted weighted gene co-expression network analysis to identify co-expressed genes.
  • Validated STAT1-mediated Th1 differentiation in vitro and in vivo DR models.

Main Results:

  • Identified the hsa_circ_0087100/hsa-miR-6743-5p/STAT1 axis as a key component in Th1 cell immune infiltration.
  • Confirmed aberrant expression of this ceRNA network and STAT1-mediated Th1 differentiation in DR.
  • Demonstrated the involvement of this pathway in both cellular and animal models of DR.

Conclusions:

  • The hsa_circ_0087100/hsa-miR-6743-5p/STAT1 ceRNA network plays a significant role in modulating Th1 cell differentiation in diabetic retinopathy.
  • This study provides novel insights into the molecular mechanisms underlying immune responses in DR.

The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

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...

iPS Cell Differentiation

The ability of induced pluripotent stem cells or iPSCs to differentiate into most body cell types has stimulated repair and regenerative medicine research over the past few decades. iPSC-derived blood cells, hepatocytes, beta islet cells, cardiomyocytes, neurons, and other cell types can repair injuries or regenerate damaged tissue in diseases such as diabetes and neurodegenerative disorders.

Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

Regulation of Hematopoietic Stem Cells01:01

Regulation of Hematopoietic Stem Cells

All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...

TGF - β Signaling Pathway01:16

TGF - β Signaling Pathway

The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors...
