TUNEL labeling of tissue slides would tell you roughly how many apoptotic
cells are present on the slides. or you can try Hoechst staining for DNA
fragmentation. apoptotic cells are stained more bright for Hoechst, which is
thought due to change of chromatin structure. this is usually done with
propidium iodide staining, which stains dead cells bright. so apoptotic cell
is propidium iodide dim, and Hoechst bright. membrane structure change occurs
during apoptosis, and annexin V binds specificall

Apoptosis is a highly regulated process of programmed cell death that
culminates in the condensation of chromatin,the degradation of chromosomal DNA,
and eventual removal of damaged cells from a healthy organism. Caspases,
central regulators of the apoptotic program, are a conserved family of cysteine
acid proteases that exist as dormant zymogens until activated by an apoptotic
stimuli. This leads to a cascade of caspase cleavage, resulting in the eventual
proteolysis of key proteins involved in

很多问题要解答:比如,这许多stress的共同点是什么,有多少蛋白被arginylated才
会trigger cell death,或者何种蛋白被arginylated才会trigger cell death. 你的文
章和原来的文章有可能并不是非黑即白,可能是某蛋白被降解而细胞得以生存或者整个

妹子眼光不错。你说的那个到底哪个或者哪些蛋白被修饰导致出现不同后果的问题也就
是我们第一稿最引起争议的部分。领域里面关于这个问题最早的文章其实没有大错,只
要他们小心的引用那个文章不要把它的结论扩大化的话。但是领域里面的错误在于他们
用了一个错误的前提,以为这个酶在不同场合下的底物都是一样的,结果就有人乱引申
了。然后渐渐的就有人三人成虎,就有人认为这个酶肯定就是不分场合都是anti
apoptotic的,然后
居然就有人号称做出了这样的结果(和我们文章里一样的细胞,一样的处理方法,但是
相反的数据),让我哭笑不得都不知道他们那些数据是怎么来的。我们在第一稿里有很
明确的数据指出说这个假设是错的,并指出说这个酶在不同情况下不但底物不一样,
而且后果也不同。然后一堆人大怒,要么就是说我胡说八道,要么就一定要我指出在

物没有上千也有几百,我不肯轻易的对此下结论。倒不是我们手头没有几个现成的底物

我完全同意你的看法. MT的作用,应该不限于release pro-apoptotic factors,XD的主要
贡献在于release pathway的发现,当然还有extrinsic和intrinsic pathway之间的
crosstalk,不过我更欣赏MT作为一个unit在apoptosis中的作用.这样来说的话,release
factors只是
其中一种作用方式,XD如果当时接着去挖掘更多的MT作用,可能地位还会更高.
我记得他说过他当年思考过为什么进化会选择MT来调控apoptosis,可惜当时人们对MT
在apoptosis中的作用估计的太简单了,以为XD的工作一出来,就差不多搞定了,XD自己
估计也是这么认为,从inverterbrate animals来看,既然这些物种里面MT上很多蛋白在
不需要cytoc的情况下就可以调控apoptosis,那么有理由相信mammalian system里面这
些pathway
也会很重要,如果XD当时把这个也一举搞定,那就太牛了.
现在有些晚了,概念已经有了,剩下的就是细枝末节了.

Really? Could you please describe what mediates apoptotic cell death except
for caspases?

这两个assay有问题是肯定的,但是用作purification assay(or assay for RNAi
screen)到底具体技术问题是啥呢?要说晓东当年的apoptotic assay,先用DNA
ladder,后用caspase cleavage,也都未必一定要和apoptosis有关吧 但是能purify出
正确的东西就成呀

在用

the problem of "p62 degradation, lc3 induction.." is that they are not
endpoint for autophagy, so they can go either way... can indicating either
enhanced or defective autophagy (different stage) at the same time,plus a
definitive assay for activated autophagy is not clear? so it seems that they
are a little bit harder than cytochrome C or other mito-apoptotic factor
purification story before. It actually holds true in lots of cellular
pathway, sometime we know the involvement of protein first b

没用过SC的Bcl2,它家的Mcl-1很好用
另外Cell Signaling的Bcl-2超级差

我博士导师需要马上招一个博后,非常非常nice的一个美国人。广告全文在下面,有兴
趣的可以直接联系他,位置是在UW-Madison,谢谢。
这个工作是部分延续我们实验室以前做的一部分化学的工作,这个位置是AICR的
funding资助做后面的机理工作,所以相关的文章很多还没有发表出来。有兴趣的可以
直接联系他,或者想知道实验室情况的也可以问我,谢谢。
我已经毕业了,我的博士老板是我这么多年遇到的最nice和对我事业帮助最大的人,所
以帮他把广告贴在这里。

Dear PLoS Biology editor:
I would like to submit a presubmission inquiry regarding suitability of our
manuscript, "Subversion of cellular autophagy pathway by RNA viruses" by
William T. Jackson, Thomas H. Giddings Jr., Sara Mulinyawe, Ron Kopito and
Karla Kirkegaard for publication in PLoS Biology. Cellular autophagy is a
field that is just entering a period of rapid discovery, because the
mammalian homologs for the many yeast genes that affect autophagy have v... 阅读全帖
