Insights

Deubiquitinases (DUBs) regulate the transforming growth factor-β (TGF-β) pathway. Dysfunctional DUBs disrupt TGF-β signaling, promoting cancer progression and metastasis, highlighting DUBs as potential therapeutic targets.

Area of Science:

  • Molecular Biology
  • Cellular Signaling
  • Cancer Biology

Background:

  • The transforming growth factor-β (TGF-β) pathway is crucial for cellular functions.
  • Aberrant TGF-β signaling in cancer drives invasion, metastasis, and epithelial-to-mesenchymal transition (EMT).
  • Targeting pro-oncogenic TGF-β responses is a developing cancer therapy strategy.

Purpose of the Study:

  • To review the role of deubiquitinases (DUBs) in regulating TGF-β signaling.
  • To explore how DUBs control Smad and non-Smad TGF-β pathways.
  • To understand DUBs' contribution to TGF-β misregulation in cancer.

Main Methods:

  • Literature review focusing on deubiquitinases (DUBs).
  • Analysis of DUBs' mechanisms in controlling TGF-β pathway components.
  • Examination of DUBs' role in cancer-associated TGF-β dysregulation.

Main Results:

  • Deubiquitinases (DUBs) are key regulators of TGF-β pathway components via the ubiquitin system.
  • Specific DUBs modulate both Smad and non-Smad signaling arms of the TGF-β pathway.
  • Altered DUB expression or function leads to TGF-β pathway misregulation in cancer.

Conclusions:

  • Deubiquitinases (DUBs) play a critical role in controlling TGF-β signaling.
  • DUBs are implicated in the development and progression of various cancers.
  • Targeting DUBs offers a promising avenue for cancer therapy by modulating TGF-β responses.

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...

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...

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...

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...
