ABSTRACT
Objective:
To investigate the role of Akt signaling pathway in the regulation of breast cancer bone metastasis induced pain behavior in rat.Methods:
Model rats were randomly divided into three groupsModel group,Model+GSK690693 group and Model+ Saline group.On PID 13,14 and 21,Model+GSK690693 group rats were intrathecally injected with GSK690693,a specific inhibitor of Akt.Model+Saline group were injected with saline instead.The pain related behaviors were respectively recorded on PID 0,7,14 and 21.The expression ofp-Akt in DRG used for western bloting were examed on PID 21.Results:
After the injection of Akt specific inhibitor GSK690693 by intrathecal,In the Model+GSK690693 group,the threshold value of mechanical contraction reflex was increased,the spontaneous pain behavior and the expression of p-Akt in DRG decreased.On PID 14 d and 21 d,the pain behavior of rats in Model+GSK690693 group was significantly different from that of Model+Saline group and Model group (P<0.01);On PID 21 d,There was significant statistical significance (P<0.01) on the expression of p-Akt and Model in the ipsilateral Model+GSK690693 of DRG group,which was statistically significant (P<0.05) compared with the Model+Saline group.Conclusion:
Intrathecal injection of Akt specific inhibitor GSK690693 inhibits rat pain related behaviors induced by bone metastasis in rat breast cancer.
