q*****n 发帖数: 331 | 2 For mouse experiment, you are going to need large quantity of antibodies or
small kinase inhibitors. It is unrealistic to buy them from bio-reagent
company.
what your boss can do is to set up collaborations with big people working in
the IGF field who has the antibody or inhibitor, or collaborate with
pharmaceutical company. For example:
OSI: OSI-906
BMS: BMS-754807
You can search pubmed to find references for these two drugs and author
information.
Good luck! |

The Shang Nature paper kind of propose 1, PAX2 is a transcription target of
ER, 2. PAX2 is positively correlated with tumor growth.
However, the 2008 Nature paper says that PAX2 is a co-repressor of HER2 gene
transcription, which is tyrosine receptor kinase implicated in malignancy
transformation. I am not sure about HER2 amplification or any functional
roles in endometrical cancer. But still the two papers' conclusions seems
very different. |

m******m 发帖数: 535 | 6 刚刚接触细胞生物学,没做过knockdown,这里问两个关于mammalian细胞knockdown的
初级问题,请大家不要笑话。
1) 准备在raw cell line 中 knockdown一个kinase,初步看看对下游cytokine的表达
有没有影响,看文献有人用Dharmacon的siRNA pool转化,有人用lentivirus shRNA,
请问哪种方法更简单?
2) 如果直接转化siRNA,等3-4天以后,细胞都分裂了好几代了,是不是每隔细胞内
的siRNA的量减少很多,这样是不是knockdown的效果就不好了?
3) 为什么siRNA可以直接转化knockdown基因表达,但是好像很少人直接转化shRNA去
knockdown的?为什么shRNA都要科隆在plasmid载体或者virus载体内呢?直接转化难道
不能被dicer酶加工变成siRNA吗?(因为从文献上查到了一个shRNA的序列,如果能直
接合成然后象siRNA那样转化,岂不是能剩了买siRNA的钱,又剩去了科隆shRNA到载体
的时间)。
比较初级的问题,请别笑话!
谢谢! |

i*****g 发帖数: 11893 | 18 我们就是把负责做那个修饰的酶给KO了,然后pathway A 和 B 同时出问题了。
然后我们把修饰好的蛋白扔进去,发现该蛋白和pathway B colocalizes, 而且recue
了pathway B,但是对pathway A就没有这个效果。
其实这个东西对pathway A到底有没有作用我们不太关心(阴性结果不说明就没有关系
)因为针对于那个蛋白和pathway A的文章超过一千篇,所以是一个没有什么意思的方
向,所以我们那个文章里面没有对pathway A下任何结论。
不过对于pathway B的结论应该是没有问题的吧?因为能够很明确的rescue, 而且很明
确的colocalizes.
批注:全部症结在此,这个叫Involved,确实没有mechanistic,
所谓mechanistic,就是A蛋白作用B蛋白,B蛋白作用C蛋白,C蛋白是公认的教科书功能
,无需多说。这就是我们这个时代的研究路数。
比如说,C是myosin,解释了宏观肌肉收缩,B是myosin kinase,A是某蛋白,能在某个

s******y 发帖数: 28562 | 19 你说得很有道理。我们那片文章确实没有所谓的mechanistic insight,
这个我们也知道。只不过一开始我们以为我们做的东西非常新,而且在组织里面
找到了直接证据,所以以为很重要。相比之下,那个发了上千篇文章,以及超过50篇
CNS的pathway A, 其实就是在培养的细胞里面最明显而已,在组织里很难找到支持证据
,以至已经有人开始质疑那个pathway A在动物体内到底有没有用。
所以我们觉得我们找到的那个蛋白对pathway B的关系可能才是真正在体内有作用的关
系。在此前提之下,我们天真的认为,那些什么mechanistic insight 是follow-up 的
文章做得。
不过,真的要找mechanistic insight 其实也不是不可以,就是看要花多少时间的问题
了。
