Although axons are generally considered to lack the ability to synthesize proteins, the Mauthner axon (M-axon) of the goldfish has been reported to contain some of the basic components of the translational machinery, such as transfer RNA (tRNA), ribosomal RNA (rRNA), and ribosomes. To determine if the M-axon also contains mRNA, we isolated samples of M-axoplasm free of glial contamination as demonstrated by the absence of glial-specific mRNA and protein. Reverse transcription-polymerase chain reaction (RT-PCR) of M-axoplasmic cDNA in the presence of primers for the goldfish medium-weight neurofilament (NF-M) gene produced a single product of the expected length for RT-PCR amplification of goldfish NF-M mRNA. This mRNA might direct protein synthesis of NF-M within the M-axoplasm.
