Changes in MIG-2 and INA-1 protein levels during the migration of QL.p, QL.ap, and QR.a cells. (A–C) The migration speeds during different time periods measured for QL.p (n = 11), QL.ap (n = 9), and QR.a cells (n = 8). The QL.p is effectively stationary. (D–F) The fluorescence intensity ratio measured during different time periods of migration (compared with intensity at time 0) of MIG-2∷GFP (green; n = 8–11), INA-1∷GFP (red; n = 8–12), and soluble GFP (blue; n = 10–11). Error bars indicate mean ± SD. Statistical significances of the data (comparison between the start and end points of speed and fluorescence) are determined by Student's t test. *, P < 0.025; **, P < 0.005; ***, P < 0.001.
