Finally, the anti‐tumour properties of ITPP were investigated on rhabdomyosarcoma and 9L‐glioma whose radiosensitivity has been shown to be correlated with oxygenation level.42, 43, 44 When used as a single therapy, ITPP showed no influence on tumour growth in these two models. This evidence concerns the gene TPP1 and rhabdomyosarcoma.
