Moreover, no mutations in FADD were found either in 92 samples from diverse hematological malignancies [52], in 24 lung adenocarcinomas with high FADD expression [5], in 15 osteosarcoma tumor samples [53], or in murine (14 samples) [12] and human (22 samples) [13] T-cell lymphoblastic lymphoma (T-LBL). Here, FADD is linked to osteosarcoma.
