摘要

To investigate the presence a common RNA marker(s) in plasma across various neurodegenerative diseases, we examined 6 neuro degenerative diseases including sporadic Creutsfeldt Jakob Disease. SYBR Green II staining revealed a 1.5-2.0 kb RNA in the patients' plasma, but a relatively smaller RNA in healthy donors' plasma. Northern blot analysis of the RNA revealed a RNA that could be hybridized with an oligo dT probe. The RNA size, however, differed between patients with spCJD, and those with other diseases and healthy donors. Therefore, we assumed that the RNA might possess a poly A sequence, and that it could be the mRNA of some molecule involved in disease enhancement.
