A comparative analysis to study editing of small noncoding BC200- and Alu transcripts in brain of prion-inoculated rhesus monkeys (M. Mulatta).

Small retroelements (short interspersed elements, abbreviated SINEs) are abundant in vertebrate genomes. Using RNA isolated from rhesus monkey cerebellum and buffy coat, reverse-transcription polymerase chain reaction (RT PCR) was applied to clone cDNA of BC200 and Alu RNAs. Transcripts containing Alu-SINE sequences may be subjected to extensive RNA editing by ADAR (adenosine deaminases that act on RNA) deamination.
