Most wt and mutant GTPases cause dendritic reduction, whereas ca-Rac causes process proliferation.A, Average length of the longest dendrite measured for RGCs expressing control proteins or ca-, wt-, or dn-GTPases.B, Average number of dendritic tips per RGC.C, Extended cell area of transfected RGCs (includes cell body plus closely growing, indistinguishable processes). Thenumbers in the bars indicate the RGCs that were analyzed. Error bars are SEM, and p values (*p < 0.05, **p < 0.01, ***p < 0.0001) indicate differences from control.
