ABSTRACT
Objective To obtain effective siRNA fragment of HOXA10 gene and verify its function,to supply experimental evidence for tumor prevention and curation by RNAi targeting to HOXA10 gene.Methods Three pairs of small interfering RNA targeting to the different sites of HOXA10 were designed and introduced into A549.The mRNA expression of HOXA10 of A549 was detected by semi-quantitative RT-PCR,the cell proliferation was assayed by MTT,the apoptosis was measured by flow cytometry.The most effective siRNA assay was screened and was tested the relationship between it and proliferation and apoptosis.Results The mRNA of HOXA10 was inhibited by three siRNAs in A549 cells,among which siRNA1 gave the strongest inhibiting of HOXA10 by ODR was (20.190±1.698) %.The inhibitory rate of cell proliferation was (69.793±2.092) % and the apoptosis rate was (29.593±2.670) %.Conclusion siRNA1 can specifically degrade HOXA10 mRNA and inhibit the proliferation of A549 cell and promote its apoptosis.
