Insights

Transforming growth factor beta (TGF-β) has a dual role in cancer, acting as a tumor suppressor early on but becoming oncogenic later. Understanding this complex pathway is key for developing effective TGF-β cancer therapies.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cancer Therapeutics

Background:

  • The Transforming Growth Factor Beta (TGF-β) pathway plays a complex, context-dependent role in cancer development.
  • Initially, TGF-β acts as a tumor suppressor in normal epithelial cells and early-stage tumors.
  • However, during tumor progression, TGF-β can promote oncogenesis, driving proliferation, angiogenesis, invasion, and metastasis, while also suppressing anti-tumor immunity.

Purpose of the Study:

  • To review the rationale for targeting the TGF-β signaling pathway in cancer therapy.
  • To summarize the progress in preclinical and clinical investigations of anti-TGF-β compounds.

Main Methods:

  • Literature review of studies on TGF-β signaling in oncogenesis.
  • Analysis of preclinical data for TGF-β inhibitors.
  • Overview of ongoing and completed clinical trials for anti-TGF-β therapies.

Main Results:

  • TGF-β's dual role necessitates careful consideration for therapeutic intervention.
  • Preclinical studies show promise for TGF-β inhibitors in specific cancer contexts.
  • Clinical trials are evaluating the efficacy and safety of various anti-TGF-β agents.

Conclusions:

  • Precise understanding of TGF-β pathway dynamics in oncogenesis is crucial for effective cancer treatment.
  • Targeting TGF-β signaling represents a promising therapeutic strategy, requiring patient stratification for optimal benefit.

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...
Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

Tumor Immunotherapy01:27

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.
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 Progression03:03

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...
