From what I heard, 20uM is supposed to inhibit caspase 8. Higher
concentrations (50-100uM) is assumed necessary to inhibit other caspases.

YES YES YES!!!!!
I strongly suspect your drug inhibit the metastasis of the tumor, which is
actually the killing factor of cancer!
In such case, the tumor size would not be reduced (sometimes it can even be
bigger) but the new secondary tumors and secondary colonies in lung or bone
marrow will be significantly down.
You should contact people who is the cancer field to help you to do the
metastasis inhibition test. From the information you provided, I think you
guys already found a gold mine but

来自主题: Biology版 - differences between SiRNA and MiRNA
ffff6699 is right
I just had an exam on this question:)
siRNA is exogeneous,about 21nt, usually completely complementary
miRNA is endogeneous, about 70nt, processed to give smaller, mature miRNA of
approximately the same size of that of siRNA; usually not 100%
complementary. Could result in mRNA degradation, inhibition of translation,
etc.. For translation inhibition it binds to 3'UTR most of the times but
some miRNA binds to 5'UTR or intronic regions too
This was what i wrote down and got full

In S. Pombe and A. Thaliana, miRNAs are able to induce histone modification
and heterochromatin formation, which eventually inhibit transcription.
However, it is still controversial whether miRNAs translocate into the
nucleus and inhibit trasncription in metazoans.
It is big leap if you can demonstrate this.

For my study, I proposed that our protein would have higher stability when

Cyclohexamide to inhibit the protein synthesis. By doing this, I want to
find a time point that this protein start

There are a couple of things you may need to know (assuming the gene is
indeed the correct TS gene):
1. A TS gene may not inhibit cell growth when overexpressed. This is because
the TS gene product may need to be activated. If your cells are not
challenged with the right condition, they may not respond to the TS. If the
TS gene product is analogous to some kinases, phosphatases, receptors, you
may be able to construct a constitutively active mutant and then use this
instead. If you suspect your... 阅读全帖

From a screening, we found a small molecule that can inhibit the activity of
a transcription factor. We used MTT assay to show that the small molecule
can inhibit the growth of a tumor cell line which depends on the abnormal
activation of the transcription factor. However, since the TF controls many
metabolism pathways, a reviewer asks to use a different type of assay.

3-NPA does that. 3-NPA directly inhibits succinate dehydrogenase activity.
At sub-toxic doses cells are still viable, but SDH activity could be significantly inhibited.
MTT/MTS/Calcein Am/Resazurin assays are often over-used or somewhat used
incorrectly to measure cell viability/cell number.

hyperpolarization eventually lead to inhibition of the ETC, which induces
oxidative stress by multiple mechanisms.
Oligomycin will not induce "sustained hyperpolarization".
Actually, I don't think any ETC inhibitor will induce sustained
hyperpolarization.
Usually, a collapse of membrane potential will happen after "maybe 30 mins
or even shorter" of OXPHOS inhibition.

For example, A and B are also involved in two parallel pathways downstream
of a common regulator C. Either pathway can activate p53/p21. Inhibition of
either A or B causes a feedback activation of C, thus leading to activation
of the other pathway.
