 Antitumor activity of type III interferon (IFN) in vitro. (a,b) Antiproliferative effects of different concentrations of interleukin (IL)‐28A or IL‐29 on non‐small cell lung cancer (NSCLC) cell lines were assessed by MTT assay. Cells were incubated in medium supplemented with or without the indicated concentrations of IFN for 5 days, and the MTT assay were performed as described in the Materials and Methods. Each value represents mean percentage cell growth ± SD (n = 5). The results are representative of three independent experiments. (c) Time course of growth inhibition of OBA‐LK1 and 11–18 NSCLC lines by 5 or 50 ng/mL IL‐28A, 5 or 50 ng/mL IL‐29 or 10 ng/mL IFN‐α was assessed by MTT assay for five consecutive days. Each value represents the mean absorbance ± SD (n = 5). The results are representative of three independent experiments.
