Activation of Rho is required for ligand-independent oncogenic signaling by a mutant epidermal growth factor receptor.

Abstract excerpt

Mutations in the epidermal growth factor receptor have been identified in several human tumor types, including gliomas. These receptor mutants have deletions in their extracellular ligand-binding domains and are, therefore, no longer regulated by ligand, resulting in constitutive activation of the receptor kinase. These mutants have been proposed to transduce oncogenic signals via ligand-independent signaling...
