来自主题: Biology版 - 本期Nature有三篇关于Lkb1的paper
比如一般上百万癌细胞移植才能长肿瘤,但是根据一些marker筛的一些subpopulation,
可能效率高几百上千倍,这就是号称里面有CSC,应用是很多drug如果只杀普通细胞而
不杀CSC,治标不治本,还有抗药性。
Sean他们让效率提高百万倍,所以可以一个细胞一个细胞研究,他的观点是白血病里面
ms是由CSC的,但是melanoma那些通过普通assay发现的CSC marker都不对,ms每个细胞
都可以变成新瘤

谢谢先~~
melanoma难道每个细胞都可以看成是cancer stem cell?
还有这些cancer stem cell的marker是不是用一般adult stem cell的marker来筛选?

原来是这样啊~~~
有没有可能within these melanoma cells,会有类似lateral inhibition的现象,所以
导致有些细胞表达CSC的marker,另外有些不能?
我不懂HSC,是不是HSC的marker很确定了?那个MSC,NSC这些Adult stem cell的marker
还是很有争议的,尤其是MSC~~

those are good drugs to extend life span but still have long way to go and
improve. Erlotinib's resistance is pretty normal. PLX's resistant is pretty
normal too. And melanoma becomes much more aggressive in resistant patients
after PLX treatment. Basically hospice is the only way to go after that.

Hi ,
Can anybody here please tell me where to buy tumor cell lines such as human
melanoma, glioma and non small cell lung cancer cell lines? How do you know
if the cell line has been tested for rodent or human transmissible pathogens
? Will the company provide these documents?
Thanks in advance!

多谢楼主了, 我确实不知道从哪查 the materials have been tested on rodents or
human transmissible pathogens. 我需要这些资料.今天下午给公司的technic
support打电话, 可惜他们已下班了. 如果您愿意邦我查, 那真是太感谢了.
三种cell lines:
Glioma: C6(CCL-107)
NSCLC: NCI-H1299(CRL-5803)
Melanoma: B16-F10(CRL-6475)
其实我也不知道哪种更好,更容易接种. 我们的目的是造肿癌模型后,用化疗药物诱导AP
site形成,然后对AP site进行定量的检测. 如果楼主能给予点拨的话,感激不尽!!!

How do BRCA1 and BRCA2 gene mutations affect a person's risk of cancer?
Not all gene changes, or mutations, are deleterious (harmful). Some
mutations may be beneficial, whereas others may have no obvious effect (
neutral). Harmful mutations can increase a person’s risk of developing a
disease, such as cancer.
A woman’s lifetime risk of developing breast and/or ovarian cancer is

我也来说说check-piont blockade。
首先效果并没有楼上说的好。Ipilimumab(anti-CTLA-4) objective response
rate在10%左右(各个地方PhaseIIItrial的效果不一),最好的在MSKCC,也在15%左右
。真正有survival benefit的人群在10%不到,提高的average surivival只有3个月。
考虑到toxicity,这个药目前只在PhaseIII和VI的melanoma上用,就是因为那些病人存
活率不超过5%,等于死马当活马医来治疗。希望能有那么10%不到的人能够中奖且收益
。你说的50%的response,包括了CR,PR,和SD,意义不大。在其他的恶性度比较高的

实验过程:KO和WT bone marrow derived DCs各1million,sc flank打老鼠,7天后在

完全没长。第二次,现在是种了B16后第8天了,打了KO DCs的老鼠tumor很明显,可是

1million B16细胞应该长得很快.我一般接种10^5个, 10天左右就可以摸到了.刚开始做
的时候也有过不长肿瘤的情况,还很兴奋.最后发现可能是实验细节上的问题.
我是做疫苗的,后来我就直接对那些不长的老鼠再接种一遍B16. 要是保护作用是真的,
那就还是不会长,或者至少要慢的很多. 不了解你的实验目的,或者也可以这样确认肿瘤
确实是不长.

谢谢你的建议。我的情况我后来想想可能不是B16接种的问题,因为种在同一个cage里
另一半老鼠身上的肿瘤全都长了。唯一的问题可能出在bone marrow derived DCs上。
可是我就是想不出DC究竟出了什么问题才会让B16完全不长的。不过我打算还是take你
的suggestion,等到14天要是WT还是没动静,就再challenge一次。等到问题解决了来

如果你能好好读一些关于CTLA-4治疗效果的文章,就会知道这个药物和许多化疗药也没
有什么大的不同:第一,毒性大的很,第二,只对melanoma有效,第三,有效10-15%
,第四,。。。。你自己study吧。PD-1和PD-L1那就好太多了(也要你自己study才会
印象深)。这些药物一旦批准,CTLA-4就是垃圾了。James Allison现在就是拼命打压
PD-1/PD-L1,有双重的目的。我的观察,这个Allison是个搞politics的高手,不是他
的credit也敢claim。Lieping Chen和YongJun Liu都太低调了,也是中国人的通病。这
个Lieping Chen,不仅是发现PD-L1,还根据它的功能第一个搞出治疗抗体,anti-PD-
1也是根据这个原理做的。这是个比CTLA-4好太多的药物,得到的credit比Allison可差
