Insights

Transforming growth factor beta (TGF-beta) regulates cell growth and impacts cancer. While inhibiting normal cells, TGF-beta can promote tumor growth, invasion, and metastasis in later cancer stages.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cell Signaling

Background:

  • Transforming growth factor beta (TGF-beta) is a key regulator of cell proliferation and differentiation.
  • Its role in cancer is complex, acting as both a tumor suppressor and promoter depending on the context.
  • Understanding TGF-beta's dual role is crucial for cancer research.

Purpose of the Study:

  • To review the multifaceted roles of TGF-beta signaling in cancer development and progression.
  • To explore how TGF-beta pathway alterations contribute to various malignancies.
  • To discuss potential therapeutic strategies targeting TGF-beta in cancer.

Main Methods:

  • Literature review of studies on TGF-beta signaling in cancer.
  • Analysis of TGF-beta's functions in different cancer types and stages.
  • Examination of evidence for TGF-beta's involvement in tumor growth, invasion, metastasis, and immune evasion.

Main Results:

  • TGF-beta inhibits normal cell growth but is often evaded by cancer cells.
  • In later stages, tumor-secreted TGF-beta promotes invasion, metastasis, and suppresses anti-tumor immunity.
  • Alterations in TGF-beta signaling pathways are implicated in cancer susceptibility and progression.

Conclusions:

  • TGF-beta exhibits context-dependent roles in cancer, acting as a suppressor or promoter.
  • Targeting TGF-beta signaling pathways presents a promising strategy for cancer prevention and treatment.
  • Further research into TGF-beta pathway abnormalities in specific malignancies is warranted.

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...

Cancer-Critical Genes I: Proto-oncogenes

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

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...

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...
