Insights

Rho guanosine triphosphatase (GTPases) are key molecular switches implicated in rheumatic diseases like rheumatoid arthritis. Inhibiting these GTPases shows promise for targeted therapies in treating these conditions.

Area of Science:

  • Rheumatology
  • Molecular Biology
  • Cell Biology

Background:

  • Rho guanosine triphosphatases (GTPases) function as molecular switches.
  • Dysregulation of Rho GTPases is implicated in the pathogenesis of rheumatic diseases, including rheumatoid arthritis, osteoarthritis, systemic sclerosis, and systemic lupus erythematosus.
  • Activated Rho GTPases mediate downstream pathways in various cell types (fibroblasts, chondrocytes, synoviocytes, immunocytes) to promote disease progression.

Purpose of the Study:

  • To summarize the role of Rho GTPases in the pathogenesis of rheumatic diseases.
  • To elucidate the Rho GTPase-mediated pathways involved in these conditions.
  • To discuss therapeutic strategies utilizing Rho GTPase inhibitors for rheumatic diseases.

Main Methods:

  • This review synthesizes existing literature on Rho GTPases in rheumatic diseases.
  • It focuses on summarizing their pathogenetic roles and mediated pathways.
  • The review also discusses current and potential therapeutic applications of Rho GTPase inhibitors.

Main Results:

  • Rho GTPases are significantly involved in the development and progression of major rheumatic diseases.
  • Specific downstream pathways regulated by Rho GTPases in relevant cell types have been identified.
  • Targeted inhibition of Rho GTPases has demonstrated promising therapeutic potential.

Conclusions:

  • Rho GTPases play a critical role in the pathogenesis of various rheumatic diseases.
  • Understanding Rho GTPase pathways offers insights into novel therapeutic targets.
  • Further exploration of Rho GTPase inhibitors is warranted for preclinical and clinical development in rheumatology.

Small GTPases - Ras and Rho01:24

Small GTPases - Ras and Rho

Ras and Rho are small monomeric GTPases that act downstream of receptor tyrosine kinase (RTK) and regulate various cellular processes. These GTPases switch between active and inactive states by binding to guanine nucleotides.
Three regulatory proteins control their activity:

Activation and Inactivation of G Proteins01:22

Activation and Inactivation of G Proteins

Heterotrimeric G proteins are guanine nucleotide-binding proteins. As the name suggests, heterotrimeric G proteins are composed of three subunits: alpha, beta, and gamma. They remain GDP-bound or GTP-bound inside the cells and switch between inactive/active states. The Gα subunit possesses the nucleotide-binding pocket that binds guanine nucleotides and switches between GDP or GTP-bound states. In contrast, the Gꞵ and Gγ subunits are always bound together with high...

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...

GTPases and their Regulation02:14

GTPases and their Regulation

Guanine nucleotide-binding proteins (G-proteins), also known as GTPases, are a superfamily of proteins that regulate many cellular processes, such as cell signaling, vesicular transport, and the regulation of cell shape and motility. Mutation or dysfunction of these proteins can lead to disease. There are around 40,000 known G-proteins that can broadly be classified into two groups ‒  small G-proteins consisting of a single domain and large multi-domain G-proteins.
Large G-proteins,...

Rheumatic Heart Disease I: Introduction

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...

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...
