The immunomodulatory drug Lenalidomide is one of a number of chemically modified analogs of the angiogenesis inhibitor, Thalidomide. Lenalidomide can act as an anti-tumor agent by suppressing angiogenesis and activating the immune system (1). Binding of Lenalidomide to Cereblon (CRBN), a substrate receptor for the CRL4 E3 ubiquitin ligase, causes selective ubiquitination and degradation of the zinc finger transcription factors Ikaros and Aiolos (2). A similar mechanism leads to the ubiquitination and targeted degradation of casein kinase 1α (CK1α) (3). Lenalidomide also downregulates SALL4, a zinc finger transcription factor that has been implicated in some human malformation syndromes, including Duane-radial ray syndrome (Okihiro syndrome) and Acro-renal-ocular syndrome (4). Lenalidomide (and other Thalidomide derivatives) can effectively treat multiple myeloma, mantle cell lymphoma, and non-Hodgkin follicular lymphoma (5-7) and can effectively induce remission in patients with myelodysplastic syndrome, either with or without chromosome 5q deletion (8).
