Abstract
The Na+-dependent transport system for the amino acid proline in unstimulated lymphocytes decays with a half-life of about 4 h when protein synthesis is inhibited by cycloheximide, but the system in mitogen-activated lymphocytes is more stable. However, the early increase in activity of this transport system after mitogen addition is not due to a direct effect on its stability, but is a secondary effect requiring protein synthesis.
摘要
在未受刺激的淋巴细胞中，脯氨酸的钠依赖性转运系统在蛋白质合成被放线菌酮抑制时，以约4小时的半衰期衰减，但有丝分裂原激活的淋巴细胞中的该系统更稳定。然而，添加有丝分裂原后该转运系统活性的早期增加并非由于对其稳定性的直接影响，而是需要蛋白质合成的次级效应。
