GSE67338 Expression data of human neuroblastoma IMR32 cells treated with the DHODH inhibitor Teriflunomide [118 µM]

Contributors : Sven Lindner ; Johannes SchulteSeries Type : Expression profiling by arrayOrganism : Homo sapiensNeuroblastoma is an embryonal tumor which originates from neural crest progenitor cells that fail to differentiate along their predefined route to sympathetic neurons or sympatho-adrenergic adrenal cells. It is the most common extracranial tumor of childhood and accounts for 15% of all childhood cancer deaths. Especially patients suffering from high grade or relapsed neuroblastoma have poor outcome in spite of aggressive treatment regimens including autologous stem cell transplantation. Those patients are in urgent need of additional effective therapies which demands the development of targeted approaches. Dihydroorotatedehydrogenase (DHODH) is the fourth enzyme of the pyrimidine synthesis pathway which oxidizes dihydroorotate to orotate. In recent past it became a potential drug target for cancer treatment because of its keyrole in processing essential pyrimidine nucleotides. On the basis of the existing data, functional inhibition of DHODH is considered to be promising therapeutic option for several tumor entities like advanced colorectal, breast or lung-cancers. Leflunomide is an established drug in treatment of the autoimmune diseases rheumatoid arthritis and multiple sclerosis. In the liver Leflunomide becomes converted to its active metabolite called Teriflunomide, which inhibits the activity of DHODH directly. In recent times Leflunomide is also used for th...
