Key Points

  • This research aims to understand how chronic cabozantinib exposure affects phosphorylation and motility in renal cell carcinoma.
  • Analyzed phosphoproteomic changes in renal cell carcinoma cells exposed to cabozantinib over time
  • Examined MET phosphorylation levels and associated signaling pathways
  • Investigated motility differences within the same signaling context
  • Sustained suppression of MET phosphorylation was observed under chronic cabozantinib exposure
  • Selective phosphorylation changes associated with adhesion and MAPK/AP-1 pathways were identified
  • Modest motility variations were noted, indicating possible adaptation mechanisms in response to treatment

Abstract

Chronic cabozantinib exposure is characterized by sustained suppression of MET phosphorylation and a selective adhesion- and MAPK/AP-1-associated phosphorylation program, accompanied by modest, pattern-specific motility differences observed within the same signaling context. These findings provide a systems level framework for future mechanistic and in vivo evaluation.
