Insights

MicroRNAs (miRNAs) are key regulators of bone metabolism. This review explores their role in rheumatoid arthritis (RA) bone destruction, focusing on osteoclast and osteoblast activity for potential drug targets.

Area of Science:

  • Biomedical Science
  • Molecular Biology
  • Rheumatology

Background:

  • Rheumatoid arthritis (RA) commonly leads to bone destruction, joint damage, and dysfunction.
  • This bone loss stems from an imbalance in bone metabolism, characterized by heightened osteoclast activity and diminished osteoblast activity.

Purpose of the Study:

  • To review the recent literature on the role of microRNAs (miRNAs) in regulating bone destruction in rheumatoid arthritis.
  • To specifically examine how miRNAs influence osteoclast and osteoblast differentiation and activity in the context of RA.

Main Methods:

  • Literature review of recent studies on miRNAs and bone metabolism in rheumatoid arthritis.
  • Analysis of miRNA involvement in osteoclastogenesis and osteoblastogenesis.

Main Results:

  • MicroRNAs are critical regulators of the bone metabolic network.
  • Dysregulation of specific miRNAs contributes to the imbalance of osteoclast and osteoblast activities observed in RA bone destruction.

Conclusions:

  • MicroRNAs play a significant role in the pathogenesis of bone destruction in rheumatoid arthritis.
  • Understanding miRNA functions offers potential therapeutic targets for developing miRNA-based drugs to treat RA-associated bone loss.

Osteoclasts in Bone Remodeling01:31

Osteoclasts in Bone Remodeling

Osteoclasts are cells responsible for bone resorption and remodeling. They originate from hematopoietic progenitor cells present in the bone marrow. Numerous progenitor cells fuse to form multinucleated cells, each with 10-20 nuclei. A single osteoclast has a diameter of 150 to 200 µM. These cells have ruffled borders that break down the underlying bone tissue and release minerals such as calcium into the blood in bone resorption. Osteoclasts cling to bones with their ruffled edges during...

MicroRNAs01:22

MicroRNAs

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

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...

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...
