Apoptosis in Human Osteosarcoma Cell Line SOSP-9607 Induced by Caspase-6 / 中国肿瘤生物治疗杂志

ABSTRACT

Objective:To explore caspase-6's effect on the apoptosis of osteosarcoma cell line SOSP 607. Methods: The expression level of caspase-6 in the osteosarcoma cell line SOSP-9067 was examined by RT-PCR method. The adeno-virus adv5 vector with caspase-6 gene was constructed and transferred into the osteosarcoma cell line SOSP-9607 by lipo-fection. The cell survival rate after transfection was assayed by MTT method. The cell morphological changes were observed by microscope and electron microscope, the apoptosis of transferred cells were examined by gel electrophoresis. Results:No expression of caspase-6 was examined in the osteosarcoma cell line SOSP-9607. A high expression of caspase-6 was identified by RT-PCR after the transfection. The cell growth curve declined after transferring caspase-6. Electrophoresis of DNA displayed the apoptosis ladder. Conclusion: Transferring caspase-6 into the osteosarcoma line SOSP-9607 may inhibit the growth of the osteosarcoma cell line SOSP-9607 and this effect might be achieved by inducing apoptosis.
