The QHArt-CM effect on neurite extension is blocked by the protein kinase A inhibitor KT5720. Increasing concentrations of KT5720 added at the time of plating reduced the length of neurites from dorsal root ganglia neurons exposed to QHArt-CM in a dose dependent manner. Cells immunostained with Tuj-1 antibody. Bar = 40 µm. Data represents results of three separate experiments. Neurite outgrowth expressed as a ratio to control is presented as mean ± SEM; **P < 0.01 compared to QHArt-CM alone. CM, conditioned medium.
