E2F5 and head and neck squamous cell carcinoma: Thus, these data suggest that induction of E2F5‐Drp1 complex using E2F5‐pept is associated with decreased tumor growth in response to cisplatin compared to controls (tumors isolated from Scr‐pept/vehicle‐, Scr‐pept/cisplatin‐, and/or E2F5‐pept/vehicle‐treated animals) in HPV(−) HNSCC‐xenograft‐derived tumors in SCID mice.
