 Antitumor activity of interferon (IFN) combination in vitro. (a–d) Effect of the combination of either interleukin (IL)‐28A plus 10 and/or 50 ng/mL IFN‐α or IL‐29 plus 10 and/or 50 ng/mL IFN‐α on the in vitro growth of non‐small cell lung cancer (NSCLC) lines was examined. The absorbance derived from cells exposed to the respective concentrations of interferon(s) is expressed as a percentage of absorbance of control. (a) Sq‐19; (b) LK‐1; (c) LK‐79; and (d) Lu99. Each value represents the mean percentage cell growth ± SD (n = 5). The result is a representative of two independent experiments. The results display an additive cytostatic effect of this interferon combination over the entire IL‐28A or IL‐29 concentration range tested.
