Phenylethanolamine N-methyltransferase mRNA in rat hypothalamus and cerebellum.

Using the reverse transcription polymerase chain reaction, we detected a single form of phenylethanolamine N-methyltransferase (PNMT) mRNA in hypothalamus and medulla/pons and two forms in cerebellum. These findings indicate that the PNMT gene is expressed in these brain areas and suggest that tissue specific splicing of PNMT mRNA may occur.
