TNFSF10 and head and neck squamous cell carcinoma: In addition, it was interestingly to note that in the experiments using rsTRAIL a minimum of 100-200 ng/mL was needed to evaluate the apoptosis effects (Figure 1A and 2A), whereas AAV-mediated TRAIL expression yielding only 150 pg/mL reached similar cytotoxicity to HNSCC cells (Figure 3A).
