Abstract:
ABSTRACT:Objective To study the effects of propofol on the metastasis of tumor cells related PI3K/Akt signaling pathway.Methods The breast cancer model was established by transplanting human derived breast cancer cell lines into immunodeficient mice with naked gene.The mice,inoculated successfully,were randomly divided into 4 groups:control group (C group,n =6),propofol group (P group,n =6),propofol+PI3K inhibitor (BYL71 9)group (P+B group,n =6),and PI3K inhibitor group (BYL71 9)(B group,n =6).The expressions of PI3K,p-Akt and Akt were examined by Western blot at week 4 after administration;the gene levels of PI3KR1, Akt1 and Akt2 were detected by RT-PCR at week 4 after administration;the number of metastatic lung nodules from both lungs was also observed at week 4 after administration.Results Compared with those in C group,the expressions of PI3K and p-Akt were significantly higher in P group (P <0.05),the level of PI3KR1 mRNA but not Akt1 and Akt2 mRNA was significantly increased(P < 0.05 ),and metastatic lung nodules significantly decreased (P <0.05).In B group,the expressions of PI3K and p-Akt were significantly decreased (P <0.05 ),the levels of PI3KR1,Akt1 and Akt2 mRNA were not significantly increased (P >0.05),but metastatic lung nodules significantly increased (P < 0.05 ).Compared with those in B group,in P+ B group the expressions of PI3K and p-Akt were markedly higher (P <0.05),the level of PI3KR1 mRNA but not Akt1 and Akt2 mRNA was significantly increased (P <0.05),and metastatic lung nodules significantly decreased (P <0.05).Conclusion Propofol can inhibit the metastasis of tumor cells through the upregulated and activated PI3K/Akt signaling pathway.
