Fig 2. IL-24 suppresses lung cancer cell migration and invasion.
H1299-IL24 cells were either not treated or treated with doxycycline and observed for cell migration and invasion. IL-24 inhibited tumor cell migration (A) and invasion (B) starting from 6h and sustained its inhibitory activity till 48 h at which time point the experiment was terminated (P<0.05). Bars denote standard deviation (SD).
