![Both interferons and gp130-mediated cytokines induce Ifitm3 expression.Ifitm3 protein expression can also be induced by gp130-family cytokines in cells expressing appropriate receptors. The Ifitm3 promoter alone among murine Ifitm promoters is interferon responsive. (A) Expression of Ifitm3 was determined by western blot in NIH 3T3 and RAW 264.7 cells treated for 2 days with the indicated cytokines. IFN lambda 2 failed to induce Ifitm3 expression at similar concentrations, likely due to lack of the type III IFN receptor. The gp130-family cytokine oncostatin M (OSM) was a potent inducer of Ifitm3 expression in 3T3 cells whereas RAW264.7 cells were responsive to IL-6, but not OSM. (B) Surface expression of the OSM receptor, IL-6 receptor, and gp130 by NIH 3T3 and RAW264.7 cells was determined by flow cytometry. Solid blue lines correspond to the fluorescence signal of the indicated receptor-binding antibodies and red lines show fluorescence of the isotype control. The responsiveness of 3T3 and RAW cells to OSM and IL-6 respectively (as shown in panel A) correlates with their expression of their corresponding receptors. (C) Activities of the six murine Ifitm promoters were assayed in mock-treated, IFN alpha 2-treated, and IFN gamma -treated NIH 3T3 cells transfected with plasmids encoding luciferase under the control of the indicated promoters. Ifitm1, 2, and 6 promoters appear constitutively active, and in contrast to human orthologs, insensitive to interferon stimulation. The Ifitm5 promoter shows almost no activity under any condition, consistent with its tissue-restricted expression in vivo[15]. The Ifitm3 promoter alone is interferon responsive (4.4-fold induction with IFN alpha 2; 2.2-fold with IFN gamma ). Bars show mean of triplicates ± SEM. Asterisk indicates p<0.0001 (two-factor ANOVA Bonferroni post test). (D) Cytokine regulation of Ifitm1, 2, and 3 was confirmed at the mRNA level by qRT-PCR in both 3T3 and RAW cells. Bars depict fold upregulation of the indicated transcripts following a 24-hour incubation with the indicated cytokines relative to transcript levels in untreated cells. Ifitm3 transcript levels were significantly upregulated by IFN alpha 2 (500 ng/ml) and IFN gamma (100 ng/ml) in both cells lines. As in panel (A), OSM (250 ng/ml) upregulated Ifitm3 in 3T3 cells and IL-6 (250 ng/ml) upregulated Ifitm3 in RAW cells. Ifitm1 and Ifitm2 transcript levels were not increased by interferons. Mean Ifitm1 expression increased in response to OSM treatment but the difference was not significant due to the high variance of these samples. Error bars show mean ± range of triplicates. Asterisk indicates p<0.05 and double asterisk indicates p<0.01 (1-tail t-test assuming heteroscedastic samples).
