Insights

Fibroblast growth factor receptor (FGFR) signaling aberrations drive some breast cancers, leading to poor prognosis. FGFR-targeted therapies are under investigation to treat these aggressive tumors.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Fibroblast growth factor receptor (FGFR) signaling regulates key cellular processes vital for development and tissue maintenance.
  • Aberrant FGFR signaling is implicated in various cancers due to its role in activating critical oncogenic pathways.
  • FGFR pathway dysregulation, including gene amplification and mutations, is observed in breast cancer.

Purpose of the Study:

  • To review the role of FGFR signaling in breast cancer.
  • To examine the impact of FGFR genetic amplifications and aberrations on breast tumor progression and treatment resistance.
  • To summarize current preclinical and clinical data on FGFR-targeted therapies for breast cancer.

Main Methods:

  • Comprehensive literature search of PubMed and congress abstracts.
  • Review of studies reporting FGFR pathway components in breast cancer.
  • Analysis of preclinical and clinical data on FGFR-targeted agents.

Main Results:

  • FGFR1 and FGFR4 gene amplification and SNPs in FGFR2 and FGFR4 are detected in breast cancers.
  • FGFR aberrations often result in increased signaling, correlating with poor prognosis and treatment resistance.
  • Several FGFR-targeted therapies, including dovitinib and AZD4547, are in clinical trials for FGFR-amplified breast cancer.

Conclusions:

  • Aberrant FGFR pathway amplification is a potential driver in a subset of breast cancers.
  • Targeting FGFR signaling represents a promising therapeutic strategy.
  • Ongoing clinical trials aim to identify patient populations most likely to benefit from FGFR-targeted 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...

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.
There are several types of targeted therapies against...

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...

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...

Transducer Mechanism: Enzyme-Linked Receptors

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:

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...
