Observations were made on the polypeptide and glycoprotein composition of dorsal root ganglia from streptozotocin-induced diabetic rats by sodium dodecyl sulphate (SDS)-polyacrylamide gel electrophoresis (PAGE). Silver staining of one-dimensional gels failed to demonstrate any differences between diabetic and control animals. In two-dimensional studies, good resolution of polypeptides with a mass greater than 70 kDa was not obtained, but a number of important abnormalities in the polypeptide composition of diabetic ganglia were detected. Some polypeptides recognized in the gels from control ganglia were present in high concentrations in diabetic ganglia; other polypeptides, particularly a number of basic polypeptides of low molecular mass, were only identified in the diabetic rats. Three major polypeptides showed a small shift in their isoelectric point in the diabetic animals. The glycoprotein content of the ganglia was examined by lectin binding to both one- and two-dimensional gel separations. An increase in total glycoprotein content was evident in the diabetic ganglia. A number of polypeptides with a molecular mass between 70 and 110 kDa showed heavy glycosylation. Altered glycosylation of some specific polypeptides of lower molecular mass was also seen, 7 of these showing increased and 3 reduced glycosylation. The significance of these findings is discussed.
