实验参考方法
In Vitro

In vitro activity: HIF-1 (hypoxia-inducible factors 1) is transcription factor which respond to changes of cellular environment oxygen. Chetomin selectively inhibits HIF-1 activities through disruption of the interaction of HIF-1 with its transcriptional coactivator p300. HIF-1 inhibition by chetomin effectively reduces hypoxia-dependent transcription and radiosensitizes hypoxic HT 1080 human fibrosarcoma cells in vitro. Chetomin attenuates the hypoxia-induced radioresistance of malignant glioma cell lines U251MG (DMF10: 1.35 and 1.18) and U343MG (DMF10: 1.78 and 1.48). Targeting of HIF-1 using chetomin abolishes the differentiation-inhibitory effect of hypoxia-inducible factor-1α.


Kinase Assay:


Cell Assay: In RT-PCR and clonogenic survival experiments, chetomin is added in a concentration of 150 nM to fully supplemented medium four hours before treatment with hypoxia. HT 1080 cells are then transferred to the hypoxic workstation (0.1% O2, 12 h) or to the well-humidified incubator (12 hours) without changing medium. HT1080 cells are thus treated for 16 hours with chetomin (150 nM) prior to radiation treatment.

In VivoAdministration of chetomin in combination with forskolin significantly suppresses malignant glioma growth in an in vivo xenograft model. Che-M(chetomin loaded micelles) dramatically inhibits embryonic angiogenesis, tumor-induced angiogenesis and tumor growth in zebrafish. In mouse model, Che-M suppresses tumor growth and prolongs the survival in the subcutaneous CT26 tumor model.
