I'm a bit confused now.
Dystrophy is a kind of wasting due to disease and the death of muscle cells, rite? so it does not involve the UPP in wasting?
Then, are those treatments effective for dystrophy patients like disabling Foxo...? -

Maybe because it is hotter in the afternoons, I thinks it is usually cooler in the mornings. -

what is the ubiquitin protease pathway?
It works by the following:
1- Ubiquitin labels the protein that needs that needs to be broken down by binding to it.
2- Then the Ubiquitin protein complex binds to proteosomes
3- The polypeptide protein chain starts to unfold and passes into the proteosomes
4- The Ubiquitin is released
5- The polypeptide is hydrolysed into peptides and amino acids.
If this occurs in muscle this would essentially break down the muscle, causing the patient to become weaker and weaker. -

So the answer to your question is yes, if the right atrogene is found it will be an effective way of fighting dystrophy. -

Check page 181
and also i rewrote out the diagram of how epo works.
We did a spider diagram in class of everything particularly important in the article and also key words. I also highlighted stuff in the article I thought was particularly relevant and made a note on topics to look over
This is a protein kinase cascade
page 181 in which book? I have the orange SNAB book and the revision guide -

animals allow us to do experiments which would other wise to unethical on humans so they do have a role in the respect. -

It's a pathway that basically breaks down protein in to constituent components, ie amino acids.
It works by the following:
1- Ubiquitin labels the protein that needs that needs to be broken down by binding to it.
2- Then the Ubiquitin protein complex binds to proteosomes
3- The polypeptide protein chain starts to unfold and passes into the proteosomes
4- The Ubiquitin is released
5- The polypeptide is hydrolysed into peptides and amino acids.

maybe think about hubel and wiesel's experiments on monkeys and kittens which taught us about the critical window.
animals allow us to do experiments which would other wise to unethical on humans so they do have a role in the respect. -
