Insights

Transforming growth factor-beta (TGF-β) can suppress tumors early on but promotes cancer progression later by inducing epithelial-mesenchymal transition (EMT). Targeting TGF-β signaling offers potential cancer treatment strategies.

Area of Science:

  • Oncology
  • Cell Biology
  • Immunology

Background:

  • Transforming growth factor-beta (TGF-β) has dual roles in cancer, acting as a tumor suppressor in early stages and a pro-tumorigenic factor in later stages.
  • TGF-β signaling is implicated in diverse cellular processes, including epithelial-mesenchymal transition (EMT), immune function, and extracellular matrix production.

Purpose of the Study:

  • To review recent findings on TGF-β-induced EMT and its crosstalk with other signaling pathways.
  • To discuss the role of TGF-β in the progression of lung and pancreatic cancers.
  • To explore the potential of targeting TGF-β signaling for cancer therapy.

Main Methods:

  • Literature review of recent findings on TGF-β signaling in cancer.
  • Analysis of TGF-β's role in epithelial-mesenchymal transition (EMT).
  • Examination of TGF-β's involvement in regulatory T cell (Treg) differentiation and function.

Main Results:

  • TGF-β promotes cancer progression through EMT, particularly in lung and pancreatic cancers.
  • TGF-β signaling crosstalks with other pathways, influencing tumor microenvironment.
  • TGF-β is crucial for regulatory T cell (Treg) function, involving complexes like GARP.

Conclusions:

  • Targeting TGF-β signaling pathways presents a promising therapeutic strategy for certain cancers.
  • Understanding TGF-β's complex roles in cancer progression and immune modulation is critical for effective treatment development.
  • Inhibiting TGF-β activity via latent complex regulation is a potential therapeutic approach.

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...

Intracellular Signaling Cascades01:24

Intracellular Signaling Cascades

Once a ligand binds to a receptor, the signal is transmitted through the membrane and into the cytoplasm. The continuation of a signal in this manner is called signal transduction. Signal transduction only occurs with cell-surface receptors, which cannot interact with most components of the cell, such as DNA. Only internal receptors can interact directly with DNA in the nucleus to initiate protein synthesis. When a ligand binds to its receptor, conformational changes occur that affect the...

Intracellular Signaling Affects Focal Adhesions

Integrins act both as extracellular input receivers and as intracellular processing activators. As their name suggests, integrins are entirely integrated into the membrane structure. Their hydrophobic membrane-spanning regions interact with the phospholipid bilayer's hydrophobic region. These membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors. They activate intracellular response cascades when their effectors are bound and active.

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.

Yeast Signaling

Yeasts are single-celled organisms, but unlike bacteria, they are eukaryotes (cells with a nucleus). Cell signaling in yeast is similar to signaling in other eukaryotic cells. A ligand, such as a protein or a small molecule released from a yeast cell, attaches to a receptor on the cell surface. The binding stimulates second-messenger kinases to activate or inactivate transcription factors that further regulate gene expression. Many of the yeast intracellular signaling cascades have similar...
