The impairment of slow axonal transport of cytoskeletal proteins was studied in the sciatic nerves of streptozocin-diabetic rats. [35S]Methionine was unilaterally injected into the fourth lumbar ganglion and spinal cord, to label the sensory and motor axons, respectively, and then the polymerized elements of the cytoskeleton and the corresponding soluble proteins were analyzed separately. In addition, the pellet/supernatant ratio for tubulin and actin was also assessed. Our results indicate that the velocity of slow component a (SCa) of axonal transport, particularly that of neurofilaments, was strongly reduced (by 60%) in sensory axons. At the same time, a decreased pellet/supernatant ratio of tubulin, possibly owing to a depolymerization of stable microtubules, was also observed. The transport of slow component b (SCb) of axonal transport was also impaired, but the extent of this impairment could not be precisely evaluated. In contrast, motor axons showed little or no impairment of both SCa and SCb at the time studied, a result suggesting a delayed development of the neuropathy in motor axons.
