title: Protein synthesis in heterotopically transplanted rat hearts.
abstract: This study examines protein synthesis in heterotopically transplanted rat hearts and several tissues of recipient rats. Donor hearts and recipient tissues synthesized many of the normally occurring proteins observed in tissues of unstressed rats. In addition, a stress-induced protein with a molecular mass of 71 kilodaltons was synthesized in donor heart, recipient heart and lung. Donor hearts incorporated more L-[35S]-methionine than did recipient hearts. Tissues of recipient rats also incorporated more label than the respective tissues of sham-recipient rats. These results suggest that ischemia, endured by the donor hearts during transplantation, induced these changes in protein synthesis.
