TNFSF10 and neoplasm: As a result of studying the antitumor activity of hTRAIL in vivo, it was found that on the 32nd day after the injection of particles, the volume of the control tumor (PBS) was twice the volume of the tumor (Fe3O4-PEI-pACTERT-TRAIL + magnetic field); when using the same magnetic complex without the field, the tumor size was about the same as when using only the PBS, or 10–15% less.
