你得非常肯定这个变化是真的，否则可能是瞎忙活。
第二要做的，比较快的，give them some DNA damage or other tumorigenic
drugs/chemicals，然后观察肿瘤发生的变化。
如果你那个5%的表达量是真的，什么都不做，你的KO Mice也会自然产生肿瘤并很快死

发帖数: 23 | 22 也有这种情况
但楼主说“是利用在其两个exons之间插入另一个不相关的gene，来使其原蛋白丧失功

所以严重怀疑是个genetrap knockout
后来楼主又提到“此KO mice体内有好几种此蛋白的变异体（由不同的exons变换组合而
成）”
我想这是指alternative splicing
一般用同源重组做KO时，可以在设计时避免alternative splicing的干扰。 |
