B decoy DNA reduces neurite growth from nodose neurons. P0 nodose
neurons were transfected with a YFP expression plasmid together with either a
B decoy DNA or a scrambled control variant and were incubated in medium
containing 10 ng/ml BDNF. Control transfected neurons were also grown without
BDNF. (A) Percent survival 48 hours after transfection. (B) Total neurite
length 24 hours after transfection. (C) Number of branching points in neurite
arbors 24 hours after transfection. (D) Sholl analysis of neurite arbor
morphology 24 hours after transfection. (E) Photomicrograph of a typical
neuron transfected with the scrambled control oligonucleotide and grown for 24
hours with BDNF. (F) Photomicrograph of a typical neuron transfected with the
B decoy oligonucleotide and grown for 24 hours with BDNF. Statistical
comparisons shown are with respect to the control transfected neurons,
*P<0.05, **P<0.001. Scale bars: 50 µm.
