Article Title: The effects of short-term JNK inhibition on the survival and growth of aged sympathetic neurons.

doi: 10.1016/j.neurobiolaging.2016.06.016

Figure Lengend Snippet: Fig. 5. Differential effects of JNK inhibition and NRAGE knockdown on proNGF-mediated survival and growth of old-aged sympathetic neurons. Relative survival (filled bars) and growth (open bars) of neurons from old-aged mice is shown after culture under the conditions indicated. For clarity, survival was normalized to the control cultures (A and B); growth was normalized to proNGF-treated cultures (A and C). Treatment with proNGF alone reduces the survival of old-aged SCG neurons (A and B), an effect which is blocked by treatment with AEG3248 (A), JNK inhibitor IX, or NRAGE siRNA (B). ProNGF treatment promotes growth of surviving neurons (A and C); while this is counteracted by AEG3248 (A) and JNK inhibitor IX (C), NRAGE siRNA does not inhibit proNGF-stimulated growth when compared with control siRNA. N ¼ 900. Threshold p-value for data shown in (A) ¼ 0.0083; threshold p-value for data shown in (B) and (C) ¼ 0.005. Abbreviations: JNK, c-Jun N-terminal kinase; NGF, nerve growth factor; SCG, superior cervical ganglion.
