来自主题: Biology版 - 谁来讲讲full genome sequencing?
看了Nature上那篇Inuk的原始人genome的paper,整个genome sequence出来之后,也只找到几个特征性的SNP,比如眼睛的颜色,earwax,门牙什么的。
是不是可以找很多种特征基因,只是这篇paper没专注这方面?还是特征性SNP就是不好找?
读了一下full genome sequencing的wiki,现在有这么多家公司都在开发,而且眼看成本就要到$1000以下了。 即使不提sequence出来的depth和false positive rate,就是质量极高的sequence,如果不知道怎么解释data,还是没有什么意义吧。有没有朋友了解的给介绍一下,谢谢了。

来自主题: Biology版 - Help! Public HIV whole genome sequences
Hi there.
I was trying to collect some HIV whole genome sequences as many as possible.
The only thing I found is this HIV database http://www.hiv.lanl.gov/content/index. However, I did not get any useful HIV whole genome sequence from NCBI.
Dose anyone know is there any other public HIV whole genome sequences
available?
Thanks

Just my two cents:
1. 我不反对也不支持CSC的model.但是光从mutation的普遍性来说并不能否定CSC. 我
们现在还没法确定这些genetic heterogeneity是driver 还是passager.大多数只是ca
ncer的result而不是cause。Moreover, it is possible that CSC and Non-CSCs all
have genetic changes;remember the so-called CSCs don't have to follow the
biology of typical stem cells.
If cancer strictly follows evolution model, should one imagine certain gene
tic lesions gain dominance?
As for the genomic stability, why should we believe it is promoting tumor?

A few comments on the NGS impact in the future:
1. The sequencing cost is dramatically decreasing, outpacing the Moore's law
prediction. Exome sequencing as part of patient profile will take off very
soon, and whole genome sequencing will not be far away. The cross-referenced
data will be highly valuable to healthcare industry players (insurance,
pharma, EMRs, etc), and in the long run the cost of data will be much higher
than that of sequencing.
2. So far the market is highly fragmented, with a... 阅读全帖

小弟最近在申请博后,博士在一个偏理论组做的是comparative genomics的数据分析,
主要是细菌的,博士组里的强项是phylogenetic network,个人的生信背景偏
phylogenetics和pathway modeling多些。最近看着好多在sequencing center做NGS的
同学发了一水的牛paper,很心动。想博后往sequencing上靠靠不知有否可能,比如
assembly,resequencing,structural variation或者Chip-seq, RNA-seq之类的数据

最近计划要开始做一个project是用几个deep sequencing方法来检测一种先天遗传疾病
(已被辨认是由一个控制染色体重构的单基因突变造成的)的基因组层面的缺陷(包括
甲基化,乙酰化,长距离转录等等), 刚从其他搞临床的实验室获得了三个不同病人
(分别具有该基因的不同突变位点)的细胞样品。
这几天阅读了几篇发表在genome research和Nucleic Acids Research的几篇类似的文
章发现这些工作都测了大概几十个病人的样品。一方面由于我们实验室是一个basic
research lab,无法获得更多的人类临床样本,另外一方面目前的funding也不能支持
做太多样品的deep sequencing。
因此想请教一下各位大侠想genome research, Nucleic Acids Research, genome
biology或者Human Mutation这些期刊对于这种疾病基因组学的研究有没有相关的要求
一定要多少病人的样本才可以接受,或者用我们手上这三种细胞做就可以有足够的代表
性了? 先谢谢大家啦!

他science文章的protocol里是puromycin七天,然后是drug treatment七天或十四天。

你看我昨天来问的时候就是这个上面有些糊涂。我现在也还担心:如果CRISPR
function很快,virus进细胞后表达gRNA/Cas9,马上ko了一个pathway上的基因,3天的
puromycin selection期间,没整合进genome,这个细胞也可能survive的。所以,我以
为sequencing整个genome来找呢。
既然是比较两个pool,遗漏一些或false positive是难免的。估计搞的几个就好。现在
的signal transduction的“网络”已经很成熟了,找到几个估计就会有谱了。看了
Feng zhang的method section,细胞用量很大,估计是不是考虑了整合进genome的效率
不是很高这个因素。
我这个因是新的pathway,自己有potency到了drug级别的small molecule inhibitor,
所以,就想自己试试。

3D genome seems to focus on the spacial structure of the genome. It is not
easy, because spacial structure can change during sampling and extraction.
Even totally in natural form, dynamics happens because the genome is too big
too long. Once into the structural biology field, advanced instruments are
needed, EM, X-Ray, NMR, FT-MS, etc. Good research field, but high risk and
long term.
