Dataset link Identification of Alpha Interferon-Induced Genes Associated with Antiviral Activity in Daudi Cells and Characterization of IFIT3 as a Novel Antiviral Gene

Experimental Protocol


Gene expression was initially measured in four Daudi cell groups (3 x 10(6) in 10 ml of RPMI) treated for 24 h at IFN concentrations selected to allow comparison of gene activity in AV activity environments with environments in which no AV activity was observed. These treatment groups were: (i) 0.0036 ng of IFN-alpha2c/ml (n=5) (allowing AV activity only); (ii) 0.00036 ng of IFN-alpha2c/ml (n=5) (no AV observed); (iii) 0.036 ng of HY-2/ml (n=3) (allowing AV activity); and (iv) 0.0036 ng of HY-2/ml (n=3) (no AV observed). To refine the list of genes associated with AV activity, samples showing AP phenotype (achieved by treatment with IFN-alpha2c [0.36 ng/ml] (n=3) or HY-2 [36 ng/ml]) (n=3) were compared to identically treated samples manipulated to display the AV phenotype through subsequent neutralization with anti-IFNAR1 MAb 64.10 (1 ug/ml) (n=6). Further analysis of gene expression profiles after 6 h of incubation helped indicate genes associated with early roles in IFN-induced AV mechanisms (n=6).
