Insights

Transforming growth factor-beta (TGF-β) is a cytokine crucial in cancer. While initially a tumor suppressor, it promotes advanced cancer by altering the tumor microenvironment, especially in gastrointestinal tumors.

Area of Science:

  • Oncology
  • Cell Signaling
  • Molecular Biology

Background:

  • Transforming growth factor-beta (TGF-β) is a cytokine with a dual role in cancer, acting as a tumor suppressor early on but promoting progression later.
  • TGF-β signaling involves serine/threonine kinase receptors and SMAD effectors, influencing cellular processes.
  • Its role in modulating the tumor microenvironment, including extracellular matrix modification and paracrine signaling, is critical in advanced cancer stages.

Purpose of the Study:

  • To review the multifaceted role of TGF-β in pathological processes.
  • To emphasize the specific involvement of TGF-β in the development and progression of gastrointestinal tumors.

Main Methods:

  • Literature review focusing on TGF-β signaling pathways.
  • Analysis of TGF-β's impact on tumor microenvironment and cellular interactions.
  • Emphasis on studies related to gastrointestinal cancer.

Main Results:

  • TGF-β transitions from a tumor suppressor to a tumor promoter in advanced cancer.
  • TGF-β significantly influences the tumor microenvironment through matrix remodeling and paracrine signaling.
  • Targeting the TGF-β pathway is a key strategy in current cancer therapy development.

Conclusions:

  • TGF-β plays a critical and complex role in cancer progression, particularly in gastrointestinal malignancies.
  • Understanding TGF-β's mechanisms is vital for developing effective cancer treatments.
  • Ongoing clinical development of TGF-β pathway inhibitors shows promise for various diseases.

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...

The Tumor Microenvironment02:17

The Tumor Microenvironment

Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF

Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...

Role Of Notch Signalling In Intestinal Stem Cell Renewal01:12

Role Of Notch Signalling In Intestinal Stem Cell Renewal

Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...

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...
