A Network Map of FGF-1/FGFR Signaling System

Area of Science:

• Molecular Biology
• Cell Signaling
• Biochemistry

Background:

• Fibroblast growth factor-1 (FGF-1) is a key signaling molecule in the FGF superfamily, regulating critical cellular functions like growth, differentiation, and survival.
• FGF-1 interacts with all four FGF receptors (FGFRs), influencing diverse physiological processes including development, angiogenesis, and wound healing.
• Dysregulation of FGF-1 signaling is linked to tumorigenesis, invasion, and metastasis, highlighting its biomedical significance.

Purpose of the Study:

• To address the lack of public resources for analyzing individual FGF-induced signaling pathways.
• To develop a comprehensive resource detailing signaling reactions triggered by the FGF-1/FGFR system.
• To provide downloadable pathway data and reaction maps in standard formats for research use.

Main Methods:

• Curated and compiled data on signaling reactions initiated by FGF-1 binding to its cognate receptors.
• Developed a pathway resource integrating information across various cell types and tissues.
• Made pathway data and reaction maps available through the NetPath and NetSlim resources.

Main Results:

• A novel resource detailing FGF-1/FGFR signaling pathways has been established.
• The resource includes comprehensive data on signaling reactions triggered by FGF-1.
• Pathway data and reaction maps are accessible for download in multiple standard formats.

Conclusions:

• The developed resource facilitates focused analysis of FGF-1/FGFR signaling pathways.
• This resource supports research into the role of FGF-1 in physiological processes and diseases.
• Availability of curated pathway data enhances understanding of complex cell signaling networks.
