Abstract: Objective To investigate the effect of NAIF1 in gastric cancer cell lines MKN45. Methods We constructed pLVX-Tight-Flag-NAIF1-puro plasmid with Tet-on system. DOX was added to induce NAIF1 expression in MKN45 cells. The cells were collected at 0, 6, 12 and 24 hours after DOX addition for gene expression microarray detection and biological analysis of differentially expressed genes. qRT-PCR and Western blot were used to verify the changes in mRNA and protein levels of the selected target differential genes. Results The biological analysis of gene microarray hybridization results showed that IFIT1, IFIT2 and IFIT3 expression significantly increased at 24h, qRT-PCR also showed this change, and Western blot further verified the change in protein level. However, IFIT5 showed no significant change in mRNA and gene expression. Conclusion Over-expression of NAIF1 in gastric cancer cells can promote the expression of some immune system-related IFIT family proteins.
