Values represent the average fluorescent intensity expressed in pixels within a 5 μm area located in the cell body, distal axonal segment, and growth cones. 12-Bit images were used for this quantification. Scale, 0 (black) to 4095 (white). Each value is the mean ± S.E.M. Cultures were fixed and processed for immunofluorescence 18 h after transfection. At least 50 cells were analyzed for each experimental condition.
Values significantly different from those of the corresponding control groups.
This group corresponds to cells transfected with the Δ-LIM mutant of wt-LIMK1.
This group corresponds to cell transfected with the LIM domain alone.
This group corresponds cells transfected with the Δ-PDZ mutant of wt-LIMK1.
