Abstract

Within 2 days of hatching in chicks, there are parallel increases in hepatic fructose 2,6-bisphosphate content and phosphofructokinase-1 activity. The changes observed are a consequence of feeding on the carbohydrate-rich diet of neonatal life: lack of access to food after hatching prevents changes for either parameter. The results are discussed in relation to changes in the activities of hepatic lipogenic enzymes during the embryonic/neonatal transition of chicks and the role of insulin in co-ordination of developmental processes.

摘要

在雏鸡孵化后的2天内,肝脏中果糖2,6 - 二磷酸的含量和磷酸果糖激酶-1的活性同时增加。观察到的这些变化是雏鸡新生期以富含碳水化合物的食物为食的结果:孵化后无法获取食物会阻止这两个参数发生变化。结合雏鸡胚胎/新生期过渡期间肝脏脂肪生成酶活性的变化以及胰岛素在协调发育过程中的作用对这些结果进行了讨论。
