Insights

Matrix metalloproteinases (MMPs) drive extracellular matrix degradation in rheumatoid arthritis (RA). Dysregulated epigenetic changes in RA synovial fibroblasts activate MMP genes, contributing to joint destruction.

Area of Science:

  • Biochemistry and Molecular Biology
  • Immunology and Rheumatology

Background:

  • Matrix metalloproteinases (MMPs) degrade extracellular matrix (ECM).
  • Rheumatoid arthritis (RA) synovial fibroblasts (SFs) produce MMPs, causing joint cartilage destruction.
  • Epigenetic mechanisms, including histone modifications, DNA methylation, and microRNA (miRNA) signaling, regulate gene transcription.

Purpose of the Study:

  • To review the role of MMPs in RA pathogenesis.
  • To examine the epigenetic mechanisms that dysregulate MMP gene activation in RASFs.

Main Methods:

  • Literature review of studies on MMPs, RA, and epigenetics.
  • Analysis of epigenetic modifications (histone modifications, DNA methylation, miRNA) in RASFs.
  • Review of MMP gene expression and activity in RA models.

Main Results:

  • MMPs are key mediators of cartilage destruction in RA.
  • Epigenetic dysregulation, including altered histone modifications, DNA methylation, and miRNA profiles, contributes to MMP gene activation in RASFs.
  • These epigenetic changes promote a pro-inflammatory and degradative environment in RA joints.

Conclusions:

  • MMPs play a critical role in RA pathogenesis.
  • Targeting epigenetic mechanisms may offer novel therapeutic strategies for RA by controlling MMP production.

Role of Matrix Metalloproteases in Degradation of ECM01:23

Role of Matrix Metalloproteases in Degradation of ECM

Matrix metalloproteases (MMPs) are enzymes involved in the hydrolysis of proteins and glycoproteins of the extracellular matrix. MMPs are essential for the migration and proliferation of cells through the dense matrix network, throughout embryonic development, and throughout morphogenesis. The first MMP activity discovered was a collagenase in a tadpole's tail undergoing metamorphosis. The active collagen deposition and modifications lead to the morphogenesis of tadpoles into the adult...

Epigenetic Regulation01:37

Epigenetic Regulation

Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

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...

T Cell Types and Functions01:24

T Cell Types and Functions

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...

MAPK Signaling Cascades01:07

MAPK Signaling Cascades

Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...
