DEL-22379 is an inhibitor of the dimerization of ERK with IC50 values ranging from 150-400 nM regardless of genotypes in oncogenic cells [1].
As an spatial regulator of ERK signals, ERK dimerization is essential. Impeding ERK dimerization can result in the impeding of ERK signals’ extranuclear component and hence result in curtailing tumor development and cellular transformation [1].
In HEK293 cells, DEL-22379 abolished EGF-stimulated ERK dimerization. In these cells, the EGF-induced co-immunoprecipitation of hemagglutinin- or FLAG epitopes- tagged ectopic ERK2 molecules, was abolished by DEL-22379 with an IC50 value of ~0.5 µM. In both assays, the inhibition of DEL-22379 to ERK dimerization was not associated with ERK phosphorylation. In the cytoplasm of EGF-stimulated HeLa cells, ERK dimerization was prominent, but previous treatment with DEL-22379 also resulted in no detected ERK dimmers [1].
In nude mice with some of the aforementioned tumor cell lines, DEL-22379 at a dose of 15 mg/kg inhibited ERK dimerization evidently in xenografted tumors and in liver extracts. DEL-22379 inhibited the tumor progression of A375 cells (BRAF mutant) markedly. Activated-RAS-driven tumors were very sensitive to DEL-22379. Data indicated that tumorigenesis had greater requirements for ERK dimerization than for proliferation. In tumors, treatment with DEL-22379 resulted in extensive mucinous differentiation and cell death [1].

1、一张芯片上可以同时分析成百上千的探针，这样的情况可以检测多少位点？
2、基因芯片技术通量会有多大？怎么计算？
请问，我通过基因芯片筛选差异基因，有上调的也有下调的，即FC有正值，亦有负值，那么负值怎么取log？谢谢
做蛋白质和microRNA的关系，那么先找出差异的蛋白质还是找出差异的microRNA好呢？有没有做ITRAQ和MICRORNA芯片好的公司推荐，非常感谢！
无创dna检测8号染色体缺失32.99mb，羊穿正常，基因芯片检测还是8号染色体杂合性缺失32.2mb，请教专家孩子能要吗？万分感谢
求助各位大神，点击Downloadfulltable无法下载，总是出现错误，已经排除网络的问题，不知道是否还有其他方法下载，上面有一个Datatable的表格，不知道是不是芯片平台文件？
中唐临界风险，33岁，第一胎，然后羊水穿刺加CMA基因芯片检查，染色体核型正常，4维彩超正常，医生说发育速度偏慢，但还算正常范围，CMA结果异常，如照片
从GEO和ARRAYEXPRESS下载了miRNA的表达数据矩阵，但是结果不太一样，大致两种：①数值从个位数到几万不等，而且没有小数点；②数值在10上下，有小数点。见图
请问怎么知道数据是否经过了log转换？有注释文件说明吗？还是直接判断①是没转换的，②是转换的？
