摘要：

Antibodies against human erythrocyte glucose transporters (GLUT-1) were used to determine if the transporters of embryonic and adult rat hearts have similar reactivity. On the basis of immunoblotting, these antibodies react more strongly with embryonic transporters than with adult ones. To determine if this phenomenon may be correlated with changes in the expression of transporter types during development, RNA isolated from either the embryonic or the adult rat heart was amplified by polymerase chain reaction (PCR) to identify the transporter species. Both GLUT-1 and GLUT-4 fragments were obtained among the PCR products. They were used for Northern blot analysis. The results indicate that the embryonic heart is rich in GLUT-1 mRNA; whereas the adult heart contains predominantly GLUT-4 mRNA. Thus, it appears that the major type of glucose transporter in rat heart switches from GLUT-1 to GLUT-4 during development. © 1991.
