Discovery of a dual PROTAC for degrading WDR5 and Ikaros oncoproteins as therapeutics [RNA-Seq]

Project description:WD repeat domain 5 (WDR5), a chromatin regulator associated with MLL complex and MYC oncoproteins, was shown to be critical for oncogenesis in human cancers and represents an attractive drug target. Inhibitors for targeting protein-protein interaction interfaces (PPIs) within WDR5 were developed; however, they inhibited only a part of WDR5-mediated functional interactions, exerting rather limited antitumor effects. We report a cereblon (CRBN)-based proteolysis targeting chimera (PROTAC) of WDR5, MS40, which is capable of selectively degrading cellular WDR5 and well-established imide:CRBN targets such as Ikaros (IKZF1). MS40-induced WDR5 degradation caused disassociation of MLL complex off chromatin, resulting in a decrease of global H3K4me2. Transcriptomic profiling also revealed targets of both WDR5 and imide:CRBN to be repressed by MS40. In MLL-rearranged acute leukemias, which exhibit high IKZF1 expression and IKZF1 dependency, co-suppression of WDR5 and IKZF1/3 by MS40 is superior at suppressing tumor growth not only to WDR5 PPI inhibitors but also to a VHL-based WDR5 PROTAC, MS169, which selectively targets WDR5 only. Furthermore, MS40 suppressed growth of primary leukemia patient cells in vitro and patient-derived xenografts (PDX) in vivo. Collectively, we report the discovery of a dual WDR5 and Ikaros degrader as anti-cancer therapeutic.

Transcriptomic profiling revealed that gene targets of WDR5 and IMiDs:CRBN were both repressed by MS40. In MLL-rearranged acute leukemias, which exhibit high IKZF1 expression and IKZF1 dependency, co-suppression of WDR5 and IKZF1/3 by MS40 is superior at suppressing tumor growth not only to WDR5 PPI inhibitors but also to a matched VHL-based WDR5 PROTAC, MS169, which selectively targets WDR5 only. Furthermore, MS40 suppressed growth of primary leukemia patient cells in vitro and patient-derived xenografts (PDX) in vivo. Collectively, we report the discovery of a dual WDR5 and Ikaros degrader as anti-cancer therapeutic.

Discovery of a dual WDR5 and Ikaros PROTAC degrader as an anti-cancer therapeutic.

Project description:WD repeat domain 5 (WDR5), an integral component of the MLL/KMT2A lysine methyltransferase complex, is critically involved in oncogenesis and represents an attractive onco-target. Inhibitors targeting protein-protein interactions (PPIs) between WDR5 and its binding partners, however, do not inhibit all of WDR5-mediated oncogenic functions and exert rather limited antitumor effects. Here, we report a cereblon (CRBN)-recruiting proteolysis targeting chimera (PROTAC) of WDR5, MS40, which selectively degrades WDR5 and the well-established neo-substrates of immunomodulatory drugs (IMiDs):CRBN, the Ikaros zinc finger (IKZF) transcription factors IKZF1 and IKZF3. MS40-induced WDR5 degradation caused disassociation of the MLL/KMT2A complex off chromatin, resulting in decreased H3K4me2. Transcriptomic profiling revealed that targets of both WDR5 and IMiDs:CRBN were significantly repressed by treatment of MS40. In MLL-rearranged leukemias, which exhibit IKZF1 high expression and dependency, co-suppression of WDR5 and Ikaros by MS40 is superior in suppressing oncogenesis to the WDR5 PPI inhibitor, to MS40's non-PROTAC analog controls (MS40N1 and MS40N2, which do not bind CRBN and WDR5, respectively), and to a matched VHL-based WDR5 PROTAC (MS169, which degrades WDR5 but not Ikaros). MS40 suppressed the growth of primary leukemia patient cells in vitro and patient-derived xenografts in vivo. Thus, dual degradation of WDR5 and Ikaros is a promising anti-cancer strategy.
