Expression of preproenkephalin-like mRNA and its peptide products in mammalian testis and ovary


, : Expression of preproenkephalin-like mRNA and its peptide products in mammalian testis and ovary. Proceedings of the National Academy of Sciences of the United States of America 82(21): 7467-7469

The distribution of preproenkephalin mRNA and proenkephalin-derived peptides have been examined in gonadal tissues from rats, hamsters, and cattle. A preproenkephalin mRNA band was detected in the ovaries of all three species and in hamster testis that is identical in size to the 1450-nucleotide mRNA typically found in tissues that express proenkephalin. Rat testis, on the other hand, expresses at least one preproenkephalin-like mRNA that is substantially greater in size (1900 nucleotides). [Met]enkephalin-containing peptides were also detected in each of the gonadal tissues examined. Although the abundance of preproenkephalin-like mRNA in rat testis was comparable to that in rat brain, the testicular content of proenkephalin-derived [Met]enkephalin sequences was less than 4% of the rat brain content. Together these data suggest that preproenkephalin-like mRNA in rat testis is not efficiently translated, proenkephalin-derived peptides undergo rapid turnover in this tissue, or the mRNA in rat testis has a frameshift resulting in an altered coding sequence.
