However, its clinical efficacy is limited due to poor bioavailability and stability. To overcome these challenges, curcumin analogs like EF-24 have been developed with improved pharmacological properties. In this study, we used whole-transcriptome profiling to identify the genome-wide functional impacts of EF-24 treatment in leukemia cells to improve our understanding of its potential mechanisms of action. This approach allowed us to establish a model system for associating druggable genes with clinical disease targets. We used the chronic myeloid leukemia (CML) cell line K-562 and acute myeloid leukemia (AML) cell lines HL-60, Kasumi-1, and THP-1 to conduct EF-24 treatment studies. Cell viability was significantly decreased in the EF-24 treated cells as compared to the untreated controls. We discovered that the genes ATF3, CLU, HSPA6, OSGIN1, ZFAND2A, and CXCL8, which are associated with reduced cell viability and proliferation, were consistently upregulated in all EF-24 treated cell lines. Further analysis of the tested cell lines revealed the activation of various signaling pathways, including the STAT1 regulated S100 family signaling pathway, that controlled downstream gene expression in response to EF-24 treatment. Our results elucidate the molecular mechanisms underlying EF-24 antitumor efficacy against leukemia, highlighting its multifaceted impact on signaling pathways and gene networks that regulate cell survival, proliferation, and immune responses in myeloid leukemia cells.
