Genetic or pharmacologic inhibition of casein kinase 1α (CK1α) has proven effective in suppressing the proliferation of acute myeloid leukemia (AML) cell lines with wild-type TP53. Researchers from Bristol Myers Squibb Co. recently presented the discovery and preclinical characterization of BMS-986397, a cereblon E3 ligase modulatory drug (CELMoD) designed as a molecular glue degrader of CK1α.
