ABSTRACT
OBJECTIVE:
To explore the effect and mechanism of recombined adenovirus carrying NLS-RARalpha gene on proliferation of HL-60 cells and the differentiation of HL-60 cells induced by ATRA.METHODS:
HL-60 cells was infected with Ad-NLS-RARalpha and control virus Ad-KZ. The efficiency of infection was detected by FCM. The mRNA and protein levels of NLS-RARalpha were assessed by Real-time PCR (RT-PCR) and Western blot, respectively. MTT assay were applied to determine proliferation of HL-60 cells. Cell surface differentiation antigen CD11b of infected HL-60 cell induced by ATRA was examined by FCM. The mRNA and protein levels of C-MYC of infected HL-60 cell induced by ATRA were determined by Real-time PCR (RT-PCR) and Western blot assay.RESULTS:
The efficiency of infection of Ad-NLS-RARalpha and Ad-KZ on HL-60 cell was 70%-80%. The mRNA and protein levels of NLS-RARalpha gene of HL-60 cells which infected with Ad-NLS-RARalpha were both obviously higher than that of the cells which infected with Ad-KZ and non-infected (P < 0.05). The proliferation ability of HL-60 cell infected with Ad-NLS-RARalpha was significantly increased (P < 0.05). The level of CD11b of HL-60 cell infected with Ad-NLS-RARalpha and induced by ATRA was clearly decreased than control groups (P < 0.05). The mRNA and protein levels of C-MYC gene of HL-60 cells infected with Ad-NLS-RARalpha and induced by ATRA were both obviously higher than that of the cells which infected with Ad-KZ and non-infected (P < 0.05).CONCLUSION:
The recombined adenovirus Ad-NLS-RARalpha can increase the proliferation ability of HL-60 cell, and inhibit the differentiation of HL-60 cell through reduce the expression level of C-MYC gene.
