Beclin-1 is a predictive biomarker for which tumor type?

• A. Canine dermal and subcutaneous mast cell tumors
• B. Feline dermatologic tumors
• C. Canine mammary tumors
• D. Canine cutaneous and subcutaneous mast cell tumors

Answer: (D)

Beclin-1 is tied to the autophagy pathway, which can influence how aggressively tumor cells grow and respond to stress. In canine mast cell tumors that arise in the skin and just under the skin, Beclin-1 expression has been shown to correlate with tumor behavior and patient outcomes, making it useful for predicting how the tumor will behave. That’s why it’s considered a predictive biomarker for canine cutaneous and subcutaneous mast cell tumors. The other tumor types listed do not have Beclin-1 established as a predictive biomarker in the same way.
