Insights

Fibroblast growth factors (FGFs) and their receptors (FGFRs) are crucial for cell regulation. Aberrant FGFR signaling drives cancer development and progression, prompting exploration of targeted therapies.

Area of Science:

  • Oncology
  • Molecular Biology
  • Cell Biology

Background:

  • Fibroblast growth factors (FGFs) and their receptors (FGFRs) are vital for normal cell functions including proliferation, survival, migration, and differentiation.
  • Deregulation of FGFR signaling is linked to developmental disorders and human cancers, where it can be overactivated through mechanisms like gene amplification, translocations, and mutations.

Purpose of the Study:

  • To provide an overview of FGF signaling pathways.
  • To summarize key FGFR alterations observed in human cancers.
  • To discuss the contribution of these alterations to cancer development and explore therapeutic strategies.

Main Methods:

  • Review of existing literature on FGF signaling in development and cancer.
  • Analysis of mechanisms leading to FGFR overactivation in cancer.
  • Examination of the oncogenic roles of FGFs and FGFRs in cancer progression.
  • Overview of current and emerging therapeutic interventions targeting FGFs and FGFRs.

Main Results:

  • FGFR alterations are implicated in various cancers, including breast, bladder, prostate, endometrial, lung, and hematological malignancies.
  • FGFs and FGFRs promote cancer progression by enhancing mitogenic and survival signals, facilitating epithelial-mesenchymal transition, invasion, and tumor angiogenesis.
  • Overactivation of FGFR signaling is a significant driver in multiple human cancers.

Conclusions:

  • FGF signaling pathways are critical in both normal development and cancer.
  • Targeting FGFs and FGFRs represents a promising therapeutic avenue for various human cancers.
  • Understanding FGFR alterations is key to developing effective cancer treatments.

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...
Introduction to Fibroblasts01:09

Introduction to Fibroblasts

Rudolph Virchow discovered spindle-shaped cells called fibroblasts in 1858. Inactive fibroblasts, called fibrocytes, become activated by various stimuli, such as growth factors and inflammatory cytokines. Activated fibroblasts play a crucial role in wound healing, inflammation, formation of new blood vessels, and cancer progression. Uncontrolled activation of fibroblasts results in fibrosis, the excess deposition of fibrous tissue, which can lead to scarring and affect normal organs. This...
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...
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...
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...
Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...
