AbstractTripterygium hypoglaucum (levl.) Hutch (Celastraceae) (THH) root is a Chinese medicinal herb commonly used for treating autoimmune diseases. In the present study, alkaloids of THH were prepared and their cytotoxicity against the HL-60 cell was investigated. THH-induced apoptosis was observed using flow cytometry, confocal fluorescence microscope, and DNA laddering and caspase assays. The molecular mechanism involved in the induction of HL-60 cell apoptosis by THH alkaloids was examined using cDNA microarrays containing 3000 human genes derived from a leukocyte cDNA library. Sixteen genes were identified to be differentially expressed in HL-60 cells upon THH treatment. Several genes related to the NF-κB signaling pathway and cell apoptosis (such as NFKBIB, PRG1 and B2M) were up-regulated. In addition, c-myc binding protein and apoptosis-related cysteine proteases caspase-3 and caspase-8 were also regulated. The changes in c-Myc RNA expression and c-myc protein level were further confirmed by RT-PCR and Western blot analysis. The results demonstrated that THH alkaloids induced apoptosis of HL-60 cells though c-myc and NF-κB signaling pathways.
