发生于密码子 L718 和 G719(ATP 结合位点)和 G724(P-loop结构域)的其他突变也影响了奥希替尼的耐药,但这两种突变对第一/二代EGFR 抑制剂敏感。 “off-target”耐药性:EGFR通路非依赖性耐药机制 在接受奥希替尼治疗的7%~15% 患者中观察到MET扩增,获得性HER2扩增占比仅2%~5%。针对MET扩增,临床上已有可用药...
A major challenge in the application of the CRISPR-Cas13d system is to accurately predict its guide-dependent on-target and off-target effect. Here, we perform CRISPR-Cas13d proliferation screens and design a deep learning model, named DeepCas13, to pred

On-target refers to exaggerated and adverse pharmacologic effects at the target of interest in the test system. Off-target refers to adverse effects as a result of modulation of other targets; these may be related biologically or totally unrelated to the target of interest. Both the risk ...
正确顺序应该是on target-off tumor。一种药物或者其他小分子可以特异性结合肿瘤抗原，被用来治疗肿瘤。但是它可以与肿瘤抗原与结合以外，还可以与正常组织上的某种抗原结合。这种正常组织上的抗原可以与这种药物靶向结合，即为on target，但是又不在肿瘤上，即off tumor。药物靶向识别正常组织上的抗原，会...
例如,在某些情况下,医生可能会将特定的治疗方法或药物定位到特定的肿瘤部位,这种肿瘤就称为“on-target tumor”。如果药物没有到达或影响目标肿瘤,那么这种肿瘤被称为“off-target tumor”。 总的来说,"on-target tumor" 是一个相对专业的医学术语,它的具体含义可能会根据上下文而有所不同。
on-target off-tumor effect的意思 "On-target off-tumor effect"是一个生物学术语,通常用于描述在肿瘤靶向治疗过程中出现的副作用。 以car-t治疗为例,希望靶抗原只在肿瘤细胞上表达,这样就不会对正常组织细胞造成影响。然而,一些主要在肿瘤细胞上表达的抗原,其实在某些正常细胞也存在少量表达,因此car-t靶向治疗时...

In addition, larger structural changes of the genome sequence, occurring at the intendedon-targetediting site, ...
本篇文章我们介绍一下罗氏旗下Genentech利用三特异抗体解决靶向激活T细胞的On-target off tumor效应,其主要是通过抗体同时靶向肿瘤细胞表明不同的靶点,促进抗体对肿瘤细胞的定位,并特异性杀伤肿瘤。 1 同时靶向Ly6E和B7-H4 同时靶向肿瘤细胞表面两个不...
identifying most off-targets with mutation rates superior to 0.1 %, while the number of false positives can be largely reduced with a cutoff on the off-target score. We also evaluate on-target efficiency prediction algorithms against available datasets. The correlation between the predictions and th...
