Fibroblast Growth Factor Receptor 1 (Fgfr1) Conditional Knock Out Mouse

Posted Dec 01 2011 7:00pm

Description of Invention:
Scientists at NIDDK have developed a fibroblast growth factor receptor 1 (Fgfr1) conditional knock out mouse. Fgfr1 is a member of the Fgfr family of transmembrane protein receptors with intrinsic tyrosine kinase activity. Fgfr1 is important in multiple biological processes, including mesoderm induction and patterning, cell growth and migration, organ formation and bone growth. Fgfr1 is highly expressed in central nervous system tissues and plays a critical role in proliferation, migration, and survival of neurons and glial cells. Additionally, overexpression of Fgfr1 has been associated with mammary gland transformation and may be crucial for the development of some cancers. The Fgfr1 conditional knockout mouse can be used to study development and biological processes in a variety of tissues and can provide information on signaling pathways that interact with Fgfr1 to induce genes important for critical cellular events, such as proliferation, differentiation, adhesion, movement, survival, and transformation.

Applications:
  • Basic research tool to investigate intracellular pathways dependent on Fgfr1.
  • Tool to study skeletal and neural development.
  • Model of stress-related environments such as bone fractures or tumorigenic induction.


Advantages:
  • Unlike Fgfr1 null mice that are embryonic lethal, Fgfr1 conditional knockout mice are viable and can be used to study the role of Fgfr1 in tissue and organ development.
  • Mice carrying the Fgfr1 conditional knockout mutation can be cross-bred using, for example, Cre-expressing mice to generate tissue specific knockouts of Fgfr1 and used for more detailed tissue studies of Fgfr1 signaling.
