Insights

Transforming growth factor beta (TGF-β) has dual roles in cancer, promoting tumor progression and suppressing certain cancer cells. Further research is needed to explore its therapeutic potential in cancer treatment.

Area of Science:

  • Oncology
  • Cell Biology
  • Immunology

Background:

  • Transforming growth factor beta (TGF-β) is a family of cytokines with diverse biological functions.
  • TGF-β signaling pathways are implicated in various cellular processes, including cell growth, differentiation, and apoptosis.
  • The role of TGF-β in cancer is complex and context-dependent, with evidence suggesting both tumor-promoting and tumor-suppressive activities.

Purpose of the Study:

  • To review the multifaceted roles of TGF-β in cancer.
  • To discuss the mechanisms underlying TGF-β's influence on tumor progression and suppression.
  • To highlight the potential of TGF-β and related agents in cancer therapy.

Main Methods:

  • Literature review of in vitro and in vivo studies on TGF-β in cancer.
  • Analysis of TGF-β's interactions with cancer cells and immunocompetent cells.
  • Evaluation of TGF-β's impact on tumor growth and response to chemotherapy.

Main Results:

  • TGF-β exhibits context-dependent effects on tumor cells, mediating both progression and suppression.
  • TGF-β influences tumor growth through direct cell interactions and modulation of the immune system.
  • The cytokine's role extends to chemotherapy, affecting efficacy and adverse reactions.

Conclusions:

  • TGF-β's dual role in cancer necessitates careful consideration for therapeutic applications.
  • Targeting TGF-β signaling pathways may offer novel strategies for cancer treatment.
  • Further investigation into the beneficial effects of TGF-β in tumors and chemotherapy is crucial for clinical translation.

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 are of three kinds RI, RII, and RIII. The RI...
Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

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.

Role of Hematopoietic Growth Factors01:28

Role of Hematopoietic Growth Factors

Hematopoietic growth factors are molecules that regulate the differentiation rate of hematopoietic stem cells (HSCs). Erythropoietin (EPO), primarily produced by the kidneys, plays a crucial role in erythrocyte production. When oxygen levels in the blood are low, EPO is released into the bloodstream, reaching the bone marrow, where it stimulates HSCs to differentiate and mature into erythrocytes, which are vital for oxygen transport.
Thrombopoietin (TPO), mainly released by the liver,...
