Molecular Pathology of Cancer · Pathology

Activation of a proto-oncogene into an oncogene most commonly results in:

  1. Loss of cell proliferation signals
  2. Increased apoptosis
  3. Constitutive growth signaling
  4. Enhanced DNA repair
Show answer and explanation

Correct answer: Constitutive growth signaling

Oncogenes arise from proto-oncogenes that acquire activating mutations. These mutations lead to constitutive growth signaling and uncontrolled cellular proliferation.
