Abstract

The concentration of fructose 2,6-bisphosphate and the activity of 6-phosphofructo-2-kinase are increased after infection of chick-embryo fibroblasts with the Rous sarcoma virus, or with a temperature-sensitive mutant of this virus at the permissive, but not at the non-permissive, temperature. This is observed after transformation by retroviruses carrying either the v-src or v-fps, but not the v-mil and/or v-myc, oncogenes. Comparison of the effects of the Rous sarcoma virus with those of phorbol myristate acetate on fructose 2,6-bisphosphate suggests that both result from the stimulation of a step which is rate-limiting for 6-phosphofructo-2-kinase activation and which is also controlled by protein kinase C.

摘要

用劳氏肉瘤病毒或该病毒的温度敏感突变体感染鸡胚成纤维细胞后,在允许温度而非非允许温度下,果糖2,6 - 二磷酸的浓度和6 - 磷酸果糖 - 2 - 激酶的活性会增加。在用携带v-src或v-fps而非v-mil和/或v-myc癌基因的逆转录病毒转化后可观察到这种情况。将劳氏肉瘤病毒的作用与佛波酯对果糖2,6 - 二磷酸的作用进行比较表明,两者都是由对6 - 磷酸果糖 - 2 - 激酶激活起限速作用且也受蛋白激酶C控制的一个步骤的刺激所导致的。
