Measured parameters include the transient duration measured as the time for 80% recovery back to baseline from the peak, and the [Ca2+]c level of the shoulder during the recovery phase of transients produced by depolarization with K+ of either 0.5s or 1.3s duration. Agents included either vehicle or FCCP 1μM combined with oligomycin 10μM (FCCP/Oligo). Groups included Control (C), and neurons from the 4th lumbar (L4) and L5 dorsal root ganglia after spinal nerve ligation. n is the number of neurons. The median and interquartile range (IQR) are shown for the fold change of the measured parameter produced by FCCP/Oligo application, calculated as the ratio of the second depolarization (following FCCP/Oligo) divided by the first depolarization (baseline) for each neuron. 1-sample Wilcoxon is the P of an effect of vehicle or FCCP/Oligo in that group using a one-sample Wilcoxon test (compared to a value of 1). Vehicle vs. FCCP/Oligo is the P for the comparison of vehicle vs. FCCP/Oligo in control neurons using Mann-Whitney test. Group Main Effect P is the probability of a main effect comparing the three groups (C, L4, L5) during FCCP/Oligo application, using Kruskal-Wallis. Paired Comparisons gives the P for significant paired comparisons between these groups (blank when none) using Dunn’s test.
P < 0.05.
