Abstract

Adrenaline resulted in a reversible 4-fold increase in the amount of pyruvate dehydrogenase in its active non-phosphorylated form in the perfused rat heart within 1 min. The increase was less in extent in hearts from starved or diabetic rats or in hearts from control rats oxidizing acetate, unless pyruvate was added to the perfusion medium. Increases could also be induced by other inotropic agents, supporting the hypothesis that increases in cytoplasmic Ca2+ can be relayed into mitochondria and influence oxidative metabolism.

摘要

肾上腺素可使灌注的大鼠心脏中处于活性非磷酸化形式的丙酮酸脱氢酶量在1分钟内可逆性增加4倍。在饥饿或糖尿病大鼠的心脏中，或在氧化乙酸盐的对照大鼠心脏中，这种增加的程度较小，除非向灌注培养基中添加丙酮酸。其他变力性药物也可诱导增加，这支持了细胞质Ca2+的增加可传递到线粒体并影响氧化代谢的假说。
