Transcriptomic and proteomic approach to studying SNX-2112-induced K562 cells apoptosis and anti-leukemia activity in K562-NOD/SCID mice.
SNX-2112, a novel inhibitor of Hsp90 currently used as an anti-tumor drug, induces apoptosis in multiple tumor cell lines. It destabilizes specific client proteins, but the molecular mechanism of the apoptosis effect of SNX-2112 is poorly understood. Here, we analyzed the apoptotic effect of SNX-2112 on human chronic myeloid leukemia (CML) K562 cells. Transcriptomic and proteomic approaches further revealed that caspase signals originated from mitochondria dysfunction, mediated by Akt signaling pathway inactivity. Additionally, SNX-2112 prolonged the survival time of NOD/SCID mice inoculated with K562 tumor cells. Our results demonstrated the therapeutic potential of SNX-2112 against human CML.
