Fig. 8. Ultrastructural changes in Golgi organization following PKA inhibition. Cells were incubated at 37°C with 20 µM of either H89 (A-D) or myristoyl-PKI (E) for 2 hours before fixation and processing for transmission electron microscopy. (F) The Golgi ribbon of a control, untreated cell is shown for comparison. Bars, 0.5 µm.
