Figure 7. IFN-β response is specifically associated with miR-139 treatment. PC3 cells were treated for 3 days with either miR139, miR-652 or negative mimic. Conditioned medium (CM) was analyzed by WB for IFN-β, and lysates were examined by WB using antibodies for the specified proteins, followed by β-tubulin for loading control. Two alternatively spliced isoforms of STAT1 exist, the antibody used detects both of them.
