Insights

E3 ubiquitin ligases play a role in systemic sclerosis (SSc) fibrosis by degrading key signaling pathways and influencing cell behavior. Further research is needed to fully understand their specific mechanisms in SSc.

Area of Science:

  • Biochemistry
  • Immunology
  • Cell Biology

Background:

  • Systemic sclerosis (SSc) is an autoimmune disorder causing organ fibrosis.
  • The precise mechanisms driving SSc pathogenesis remain unclear.
  • E3 ubiquitin ligases are increasingly recognized for their role in organ fibrosis.

Purpose of the Study:

  • To review the regulatory mechanisms of E3 ubiquitin ligases in fibrosis.
  • To explore their specific involvement in the pathogenesis of SSc.

Main Methods:

  • Literature review of studies on E3 ubiquitin ligases and fibrosis.
  • Analysis of documented pathways regulated by E3 ubiquitin ligases.

Main Results:

  • E3 ubiquitin ligases regulate fibrosis via ubiquitin-mediated degradation of the TGF-β/Smad signaling pathway.
  • They also influence fibrosis by promoting epithelial-to-mesenchymal transition, increasing TGF-β production, and preventing apoptosis of activated hepatic stellate cells.

Conclusions:

  • E3 ubiquitin ligases are implicated in fibrosis through multiple mechanisms.
  • Their specific roles and regulatory functions in systemic sclerosis require further investigation.

Receptor Downregulation in MVBs01:15

Receptor Downregulation in MVBs

Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that  lead to cell proliferation, migration, and differentiation. Overexpression of EGFR  stimulates cells to proliferate. Excessive  EGFR...

Regulation of the Unfolded Protein Response01:31

Regulation of the Unfolded Protein Response

Inositol-requiring kinase one or IRE1 is the most conserved eukaryotic unfolded protein response (UPR) receptor. It is a type I transmembrane protein kinase receptor with a distinctive site-specific RNase activity. As the binding mechanics of the misfolded proteins with the N-terminal domain of IRE-1 are unclear, three binding models — direct, indirect, and allosteric -- are proposed for receptor activation. Nevertheless, it is known that once a misfolded protein associates with IRE1, it...

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal01:22

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal

Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.

Regulated Protein Degradation02:58

Regulated Protein Degradation

It is vital to regulate the activity of enzymatic as well as non-enzymatic proteins inside the cell. This can be achieved either through creating a balance between their rate of synthesis and degradation or regulating the intrinsic activity of the protein. Both these regulation mechanisms play an essential role in the normal functioning of cells.
Protein degradation plays two important roles in the cells. It helps to protect cells from misfolded or damaged proteins before they lead to a...

Master Transcription Regulators02:23

Master Transcription Regulators

Master transcription regulators are regulatory proteins that are predominantly responsible for regulating the expression of multiple genes. Often these genes work in concert to drive a  complex process. Activation of a master transcription regulator can lead to a cascade of transcriptional activation necessary for that outcome. These regulators can directly bind to the regulatory sequences of the various genes involved, or they can indirectly regulate transcription by binding to regulatory...

Covalently Linked Protein Regulators02:04

Covalently Linked Protein Regulators

Proteins can undergo many types of post-translational modifications, often in response to changes in their environment. These modifications play an important role in the function and stability of these proteins. Covalently linked molecules include functional groups, such as methyl, acetyl, and phosphate groups, and also small proteins, such as ubiquitin. There are around 200 different types of covalent regulators that have been identified.
These groups modify specific amino acids in a protein....
