来自主题: Biology版 - 大家讨论一下synthetic biology吧
Thanks!
我现在主要做代谢工程(不要脸的说,阿猫阿狗都做metabolic engineering,
synthetic biology),这些circuit够fancy,但是我在想一个能够够好的调控metabolic
engineering里的基因表达的,要够fancy,有模型,有产量。
我总不能说,嘿,我的产物(酶)是oscillation的吧。
感觉吧,synthetic biology有点问题,又说不出来。

我们实验室一直在yeast做synthtic biology 当然做的比较偏应用
不过估计lz看不上我们老板 毕竟发文章水平不高 和做的偏应用也有关系。我们主要
方向之一就是发展genome wide editing tool,然后结合robot-assisited high
throughput screening筛选一些高产或者高耐受性yeast strain 也做一些cell line和
stem cell 但毕竟不是做这个出身 主要靠合作
如果要回国的话lz可以考虑下 国内大部分synthetic biology center都是他帮忙组建

楼主感兴趣的话可以看看UCSF Jonathan Weissman实验室,听说他们实验室根据cas9搞
的cas9a(activation)和cas9i (repression)效果还不错,暂时主要应用在genomic
screen上。我觉得以后用来做真核的synthetic biology非常好。同样在UCSF 的
Wendell Lim前一阵子把一些基本的基因调控原件应用在免疫细胞里面,效果还不错,
以后基于synthetic biology的基因治疗可能也有很好的发展....
搬到mit的james colins 也很好。
纯从转录调控说,个人感觉e coli 和 yeast 差别不是特别大,从 yeast 到其他的真
和模式生物差别非常大。虽然yeast同样有histone,但是对转录调控的影响比较简单。
在yeast里大概影响转录调控的variables都了解的差不多了,直接manipulate这些
variables的工具也相对齐全。在其他真核系统里,定量的研究感觉上还都是停留在对

来自主题: Biology版 - 请问什么叫Synthetic Lethal?
synthetic lethal 是个很经典的遗传学概念啦。很多时候单个基因突变没法造成明显
的表型,因为存在另一个基因,或通路什么的,可做功能补充。只有当两条通路都断掉
,个体马上灭掉。
一般叫synthetic effect, 不仅仅是lethal的。

来自主题: Biology版 - 请问什么叫Synthetic Lethal?
比如癌症,你总想筛选只杀带突变基因的细胞吧
就是 drug + mutation synthetic lethal.
基础研究找pathway,很多都是synthetic lethal/effect, 你去随便找个做经典遗传的
就知道了,

标 题: 科普一下 synthetic和conventional机油的区别
发信站: BBS 未名空间站 (Mon Feb 28 15:48:51 2011, 美东)
发动机机油是由基础油和添加剂两部分组成。其中添加剂一般包括:粘度指数改进剂、
清净分散剂、抗磨剂、抗氧化剂、降凝剂、摩擦改进剂、防锈剂、抗泡剂、其他添加剂。
基础油分合成油与矿物油两种,合成油由原油中的瓦斯气或天然气分散出来乙烯、
丙烯后,再经聚合、催化等繁杂的化学反应炼制而成。矿物油则在原油提炼过程中,分
离出有用的轻物质(如航空油、汽油等)之后,利用残留在分馏塔内的塔底油提炼而成
的。就油的本质而言,矿物油用的是原油中较差的成份,提炼技术再精进也无法将其中
杂志清楚完全;而合成油则是原油中较好的成份,加以化学反应并通过人为控制,可以
达到预期的分子形态,分子排列整齐,抵抗外界变数的能力强,故合成油质量较好,在
