| Outline of Final Research Achievements |
Amyotrophic lateral sclerosis (ALS) is the most common motor neuron disease characterized by progressive degeneration of the upper and lower motor neurons, which results in paralysis of the limbs and/or the bulbar musculature. However, because there are no specific biomarkers for ALS, it is difficult to diagnose this disease at early stages. Therefore, we compared the protein profile in cerebrospinal fluids (CSF) of ALS patients and control subjects by two-dimensional differential in-gel electrophoretic analysis (2D DIGE) and two-dimensional gel electrophoresis with immunochemical detection of protein carbonyls (2D Oxyblot). We showed that 4 proteins (serotransferrin, etc) were increased in CSF of ALS patients compared with control subjects. In addition, we found that carbonyl modification of pigment epithelium-derived factor, serotransferrin, and so forth was increased in CSF of ALS patients. This study presumes some of these proteins could be candidates of biomarkers for ALS.
