Cell signalling inhibitors

Hi guys,

Can you please list for me some cell signalling inhibitors for C. elegans (or generic) and tell me the enzyme or receptor that is inhibited?

(Preferably for tyrosine kinase, G-protein, JAK/STAT and Phosphatidylinositol 3-kinase)

Thanks :D

There are many theories and contributing factors, but, most importantly, when a cell divides by mitosis, regions of the chromosomes called telomeres are lost if the telomerase gene is not activated, which plugs and repairs these telomeres (which is why cells have a Hayflick limit (can only divide 50...

RNA has a Uracil pyrimidine base in the place of thymine in DNA as well :)

Thanks very much! Is there any compartmentalisation of carbonic anhydrase, or can it be present anywhere?

Gluconeogenesis

Hello all.

What is the origin of HCO3- where it enters at the first step of gluconeogenesis? Is it from carbonic anhydrase?

Thanks :)

I did A level maths and a little bit at Uni :/ - I could do it well, but found it slightly tedious. However, I know many mathematics enthusiasts, so it is really down to personal opinion.

I would say that I find chemistry to be the easiest science and physics to be the most challenging. I think that chemistry is possibly the most "important" as such, because it is relevant in both biology and physics. But I love biology (especially cell and molecular biology) because I pers...

Re: Intrinsic apoptosis in erythrocytes

Thanks very much for your responses. They do not have genes to activate release of cytochrome c (even then, Im not sure how they would without mitochondria. If they were to do that, they'd probably use Bax or Bak as enzyme linked receptors to kick of a MAP kinase phosphorylation cascade to signal it.

I'm afraid that animal behaviour and physiology are not at all my specialisms, but I think that B is actually correct, because such an impulse would usually be a response in such a situation - I am not exactly sure specifically to this case. Try and post this on the zoology or physiology forum - You...
