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 Vivo | Administration 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. |
Animal model | Transgenic fish Tg(flk1:EGFP); Mouse model(BALB/c mice) |
Formulation & Dosage | Chetomin was loaded in micelles; 1 mg/mL(for zebrafish); 2 mg/kg(for mouse); s.c. |
