Current Interactions:
Rb Pathway:
  • p16 → CDK4/6 inhibition: ACTIVE
  • CDK4/6 → Rb phosphorylation: BLOCKED
  • Rb → E2F inhibition: ACTIVE
p53 Pathway:
  • DNA Damage → p53 activation: INACTIVE
  • p53 → p21 induction: BLOCKED
  • p21 → CDK inhibition: BLOCKED
Cell Cycle Control
CONTROLLED

Normal cell cycle checkpoints are functioning properly.

DNA Damage Response
NORMAL

No significant DNA damage detected. Normal cellular surveillance active.

Cancer Risk
LOW

Tumor suppressor pathways are functioning normally.

Clinical Relevance

Current pathway status represents normal cellular regulation with functional tumor suppressor mechanisms.
