Phosphofructokinase activity was measured in the sciatic nerve of streptozotocin-induced diabetic and nondiabetic rats. Average steady-state phosphofructokinase activity was obtained from three consecutive segments of the mid-femoral region in the left sciatic nerve in both diabetic (4 and 24 weeks) and nondiabetic, age-matched animals. Over time, phosphofructokinase activity significantly decreased (p less than 0.05) with diabetes, with no effect demonstrated within similar age-groups. The accumulation of phosphofructokinase activity was accomplished by ligating the mid-femoral region of the right sciatic nerve for 24 h. Anterograde and retrograde axonal transport of phosphofructokinase was measured in the 3-mm segment proximal and distal to the ligature, respectively. There was a trend (p = 0.0627) towards a decline in net proximal accumulation (mean proximal minus mean background) with age. Net distal (mean distal minus mean background) activity declined by 80% (p less than 0.05) in the control group between 4 and 24 weeks of the diabetic state. However, diabetic animals did not experience the same age-related decline in retrograde transport. The findings suggest that diabetes affects the age-associated evolution of retrograde transport, presumably a reflection of the neuropathy occurring in the distal axon branches, without altering anterograde transport to any appreciable extent.
