ABSTRACT
This study was purpose to explore the down-regulatory effect of nucleostemin (NS) expression on signal molecules of PI3K/AKT/mTOR pathway belonged to candidate ways of p53-independent signal pathway in the leukemia cells. The expression of NS was interfered by using recombinant lentivirus expression vector NS-RNAi-GV248 to transfect HL-60 cells of p53 deficiency. The expression of NS and signal molecules of PI3K/AKT/mTOR pathway were detected by using Real-time PCR. The results of showed that the HL-60 cells were transfected by recombinant lentivirus vector NS-RNAi-GV248 successfully and with transfection rate up to 80%. According to results of Real-time PCR detection, the inhibition rate of NS gene was 56.5% in HL-60 cells. And the expression levels of PI3K,AKT and GβL mRNA (0.491 ± 0.084,0.398 ± 0.164, 0.472 ± 0.097 respectively) were obviously down-regulated by silencing NS, and showed statistical difference (P < 0.05) in comparison with control (1.002 ± 0.171, 1.000 ± 0.411, 1.001 ± 0.206 respectively) . It is concluded that the changes of signal molecules of PI3K/AKT/mTOR pathway positively correlate with NS down-regulation, which provides evidence for confirming PI3K/AKT/mTOR signal pathway possible as a type of NS p53-independent pathway.
