ABSTRACT
Objective To explore the effects of survivin on radiation injury and its relation to caspase 9/6,3 activity. Methods ① IEC 6 cells were treated under hypoxic environment for 8 h and followed by reoxygenation for 24 and 48 h, and then the expression of survivin was identified by Western blotting. ② After treatment with 35 Gy 60 Co , the apoptosis rate in different groups was detected with FACS and the caspase 9/6,3 activity was tested using the caspase 9/6,3 assay kit. Results Hypoxic preconditioning could induce the expression of survivin in IEC 6 cells and survivin could decrease the caspase 3 activity, resulting in reduced apoptosis rate induced by radiation. Conclusion Survivin induced by hypoxic preconditioning can inhibit the apoptosis induced by radiation by reducing the caspase 3 activity.
