Responses of CDKs and p53 in Delayed Ischemic Neuronal Death

Stroke is a debilitating disease that affects millions each year.While in many cases cerebral ischemic in jury can be limited by effectivw resuscitation or thrombolytic treatment,the injured neurons wither in a process known as delayed neuronal death(DND).Mounting evidence indicates that DND is not simply necrosis played out in slow motion but apoptosis is triggered.Of particular interest are two groups of signal proteins that participate in apoptosis-cyclin dependent kinases(CDKs) and p53-among a myriad of signaling events after an ischemic insult.Recent investigations have shown that CDKs,a family of enzymes initially known for their role in cell cycle regulation,are activated in injured neurons in DND.As for p53,new reports suggest that its up-regulation may represent a failed attempt to rescue in jured neurons,although its up-regulation was previously considered an indication of apoptosis.These observations thus rekindle an old quest to identify new neuroprotective targets to minimize the stroke damage.In this review,the author will examine the evidence that indicates the participation of CDKs and p53 in DND and then introduce pre-clinical data to explore CDK inhibition as a potential neuroprotective target.Finally,using CDK inhibition as an example,this paper will discuss the pertinent criteria for a viable neuroprotective strategy for ischemic in jury.

肠淋巴液对休克大鼠心肌特性的影响

大鼠重度失血性休克３０ｍｉｎ后，左心室内压的最大上升速率和左心室收缩压都显著下降，而左心室舒张末压却有所增高。说明心肌的收缩功能和舒张功能出现障碍，给少量淋巴液后使休克时下降的左心室内压的最大上升速率和左心室收缩压显著回升，而增的左心室舒张末压回落不明显，提示巴液改善休克心肌的收缩功能障碍，但对低血容量情况下的心肌舒功能无明显改善。
