TNFSF10 and hereditary clear cell renal cell carcinoma: Other RCC cell lines, such as clear cell renal carcinoma cell line 1 (Caki‐1), human renal cell carcinoma cell line 786‐O (786‐O), and renal cell carcinoma cell line 4 (RCC4), also exhibited TRAIL resistance due to various mechanisms, including overexpression of anti‐apoptotic proteins (Caki‐1), mutations in apoptotic pathways (786‐O), or hypoxia‐related resistance (RCC4).
