Dihydroarteminin (DHA) a derivative of Artemisia annua has a biological effect of inhibiting the proliferation and metastasis of human osteosarcoma cells and promoting apoptosis. - GreenMedInfo Summary

Regarding the Artemisia annua extract derivatives called dihydroarteminin (DHA) as the object, we studied about its influence to the proliferation, apoptosis and metastasis of human osteosarcoma cells. First, we cultured in vitro the osteosarcoma cell strain and divided them into groups, then detected the cell proliferation, apoptosis and cell metastasis, etc by multiple measurement technique. Finally, we observed the influence of DHA to human osteosarcoma cells. Osteosarcoma cells were all sensitive to DHA, and the appropriate concentration range was 10~40μM. DHA could effectively restrain its protein expression, and there was a significant difference between experimental group and control group. These finding suggest that, the Artemisia annua extract derivatives (DHA) has a biological effect of observably restraining the proliferation and metastasis of human osteosarcoma cells and promoting the tumour cell apoptosis.
