在实验性癌症恶液质中的肌肉消耗常伴有ATP依赖性泛肽 蛋白酶体溶蛋白酶系统的过度激活 ,以往在胃癌病人已显示肌肉泛肽mRNA值增加 ,提示这一溶蛋白酶系统在人体癌肿中也受到调控。为了阐明ATP 泛肽依赖性溶蛋白酶的激活状态 ,作者作实验研究如下 :取罗马CattolicadelSacroCuor Muscle consumption in experimental cancer cachexia is often accompanied by an over-activation of the ATP-dependent ubiquitin proteasome-renin system, and in the past patients with gastric cancers have shown an increase in mRNA for muscle ubiquitin, suggesting that the hemolysin system is active in human cancers Swollen is also regulated. In order to elucidate the ATP ubiquitin-dependent protease activation status, the authors make the following experimental study: Take the Roman CattolicadelSacroCuor
