The Ras and Notch signaling pathways are crucial for development and interact in complex ways. Understanding these interactions in model organisms like C. elegans and Drosophila offers insights into cancer development in mammals.

Area of Science:

  • Developmental biology
  • Cell signaling
  • Cancer biology

Background:

  • Ras and Notch signaling pathways are fundamental regulators of biological processes during development.
  • These pathways frequently intersect, exhibiting both cooperative and antagonistic interactions.
  • Classic model systems like the Caenorhabditis elegans vulva and Drosophila eye illustrate their roles in cell fate determination and pattern formation.

Purpose of the Study:

  • To elucidate the mechanisms by which Ras and Notch signaling pathways interact.
  • To explore the relevance of these interactions in mammalian development and disease, particularly cancer.

Main Methods:

  • Utilizing established developmental models such as the Caenorhabditis elegans vulva and Drosophila eye.
  • Investigating the interplay between Ras and Notch signaling pathways in these systems.
