Abstract

Circadian oscillations of liver tyrosine aminotransferase (TAT) tryptophan oxygenase (TO), alanine aminotransferase (ALAT), aspartate aminotransferase (ASAT), and glutamate dehydrogenase (GLDH) in temporal pattern of protein input have been investigated. Cosinor analysis of oscillations parameters revealed the glucocorticoid induction of TO activity and protein induction of TAT activity rhythm. ALAT, ASAT, and GLDH activities showed 24 h fluctuations, but the regulation mechanisms remain unclear.

氨基酸分解代谢酶在养分输入时间模式下的昼夜振荡余弦分析。

研究了肝脏酪氨酸转氨酶(TAT)、色氨酸加氧酶(TO)、丙氨酸转氨酶(ALAT)、天冬氨酸转氨酶(ASAT)和谷氨酸脱氢酶(GLDH)在蛋白质输入时间模式中的昼夜振荡。振荡参数余弦分析显示糖皮质激素诱导TO活性和蛋白质诱导TAT活性节律。ALAT、ASAT和GLDH活性均呈现24 h波动，但调控机制尚不清楚。
