Treatment of cultured B35 neuroblastoma cells with
palladin antisense results in impaired neurite outgrowth. (A) B35 cells
were transfected with GFP plus control (sense) construct or GFP plus
palladin antisense construct and then fixed and stained for palladin.
Arrows point to transfected cells. Although antisense transfection led
to a reduction in palladin immunoreactivity (right), transfection with
the control construct did not (left). (B) B35 cells were transfected
with GFP alone, GFP plus empty vector, GFP plus sense construct, or GFP
plus palladin antisense construct. The top row of images shows
undifferentiated control cells, and the second and third rows show
cells stimulated with 1 mM Bt2cAMP. Note that cells treated with
palladin antisense failed to extend neurites in response to Bt2cAMP
(far right).
