Summary
Fibroblast growth factor receptors (FGFRs) are crucial for tissue development and repair. Aberrant FGFR signaling drives cancer, prompting targeted therapies, though tumor complexity can cause treatment resistance.
Area of Science:
- Molecular Biology
- Oncology
- Cell Signaling
Background:
- Fibroblast growth factors (FGFs) and their receptors (FGFRs) exhibit pleiotropic effects and are widely expressed.
- The FGF/FGFR axis is vital for normal tissue development, homeostasis, and repair.
- Dysregulated FGFR signaling is implicated in various diseases, particularly cancer.
Purpose of the Study:
- To review the structure and function of FGFs and FGFRs.
- To discuss common FGFR aberrations in cancer.
- To explore the therapeutic potential of targeting the FGF/FGFR axis in cancer treatment.
Main Methods:
- Literature review focusing on FGFR signaling pathways.
- Analysis of genetic aberrations (mutations, fusions, amplifications) in FGFRs in cancer.
- Examination of therapeutic strategies targeting the FGF/FGFR axis.
Main Results:
- FGFR signaling is complex and essential for normal physiological processes.
- Aberrant FGFR signaling, including mutations and gene fusions, contributes significantly to tumorigenesis.
- Numerous targeted therapies, including inhibitors and antibodies, are being investigated and utilized in cancer treatment.
Conclusions:
- Targeting the FGF/FGFR axis is a promising therapeutic strategy in oncology.
- Tumor microenvironment heterogeneity and signaling complexity can lead to resistance to FGFR-targeted therapies.
- Further research is needed to overcome therapeutic resistance and optimize FGFR-targeted treatments for cancer patients.

02:38Mitogens and the Cell Cycle
7.0K
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...

7.9K
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.

03:03mTOR Signaling and Cancer Progression
3.9K
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.

02:23Abnormal Proliferation
4.7K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

01:24Regulation of Angiogenesis and Blood Supply
2.9K
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...

02:54Canonical Wnt Signaling Pathway
9.2K
The gene encoding the main signaling molecules of the Wnt signaling pathways (the Wnt proteins) was discovered almost four decades ago by Nüsslein-Volhard and Wieschaus. They identified and originally named the gene "wingless" (wg) after a phenotype discovered during their landmark genetic screen in Drosophila for body pattern defects. At around the same time, another researcher named Harold Varmus found that a murine tumor virus activates the mammalian wg homolog, Int-1, which...
