Daigeler et al. [21] compared the differential expression of proapoptotic genes tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL)-2, FAS cell surface death receptor, TNF ligand superfamily member 5 (TNFRSF5)/CD40 and antiapoptotic genes proliferation and apoptosis adaptor protein 15 (PEA15), B-cell lymphoma 2 (BCL2)-related protein A1 (BCL2A1), nerve growth factor-β (NGFB), and others using microarrays in 19 primary cultures of liposarcoma after doxorubicin treatment. Here, CD40 is linked to liposarcoma.
