AEG3482 is a small-molecule inhibitor of Jun kinase (JNK)-dependent apoptosis. [1,2]
Jun kinases, also called Jun N-terminal kinase stress-activated protein kinases. Activation of the JNK signaling pathway is amajor event in neuronal apoptosis. This is proved by pathological specimens from Alzheimer’s disease, as well as samples from mouse models of Alzheimer’s and Huntington’s disease, reveal activated JNK. [2]
AEG3482 blocks apoptosis induced by the p75 neurotrophin receptor (p75NTR) or NRAGE, which is p75NTR’s cytosolic interactor,. AEG3482 inhibits proapoptotic JNK activity. AEG3482 induces production of heat shock protein 70 (HSP70) which is an endogenous inhibitor of JNK. HSP70 accumulation is required for the AEG3482-induced JNK blockade. [1]
As described, activation of C-jun N-terminal kinase (JNK) signaling is associated with neuronal cell death. AEG3482 interacts with heat shock protein 90 leading to inhibition of JNK and blockade of neuronal apoptosis. So AEG3482 can serve as useful tools for basic research, and it may have therapeutic potential for the treatment of acute and chronic neurological disorders. In the neuropathologicalstate, the chaperone-mediated stress response may be primed for response to Hsp90 inhibitors; and AEG3482, may be selective neuroprotective agents.[1,2]

各位大侠：小弟最近做个长片段的CDNA与T载体的连接，片段大小6.4K，载体选用的是pUC19和pGEMT-easy,反转录酶用的是RevertAidTirstStrandcDNASynthesisKit(#K1621)，CDNA第二链的扩增用的是LATaq。我是用纯病毒的RNA做模板，操作步骤严格按照说明做的，也曾经有一次获得过电泳图清晰显示的是全长6.4KB左右的片段，与载体连接，结果筛选到的几个克隆，插入的片段仅有2KB左右，奈何？可最近几次再用此反转录试剂盒却不能得到所需片段。在此，小弟想问问大家，你们是否遇到同样的问题，是如何解决的？所用的试剂（载体和酶的选择）和方法是什么，可以告诉后来者，共同进步吧。
