comment Question about cell signaling pathways (RTK, Jak-Stat, SMAD, etc)
see my comment on the post below -- I could have done a much better job saying what I was confused about in writing this question.

comment Question about cell signaling pathways (RTK, Jak-Stat, SMAD, etc)
Thank you, but I do understand that -- I suppose I didn't write my question very well and I was initially confused because my book explains the receptor tyrosine kinase (RTK) pathway in the context of the fibroblast growth factor family of paracrine factors, because the FGF receptors are RTK's. I was wondering how much of this "sharing" takes place -- how many of these ligands use the RTK pathway? My book implies that quite a few do, but isn't explicit about which.

In contrast to each and every one that I listed having its own distinct pathway.

comment Simple diffusion of lipid-soluble molecules through phospholipid bilayer — does anything get “stuck” in transit?
Thank you -- I wasn't thinking about turnover and synthesis of new membrane lipids, and this is exactly what I needed. I thought for sure that at least theoretically a molecule could remain in between the bilayers, but I agree that the amount of this occurrence is relatively insignificant.

comment Why do cells have an average 'life span'
Henrietta Lacks had cervical cancer, and her cancerous cells somehow survived in culture (I don't know if this was due to proper handling by the lab staff or otherwise).

comment Why does trans fat decrease hdl's?
You might find this interesting: jn.nutrition.org/content/135/9/2075.full It doesn't directly answer your question, but it discusses potential mechanisms and is a good read in any case.

comment Which Receptors are Involved in the antidepressant effects of SSRIs?
I noticed you've asked a few questions about antidepressants recently--did you know that there's a cogsci stack that you can try too? I'm not saying these questions should be there instead of here, just saying you could ask in both places and see if it's helpful.

comment Why does trans fat decrease hdl's?
cis fats don't increase LDL. I think you've got them mixed up. Is your question why trans fats exert an effect on both HDL and LDL?

comment Fibonacci sequence in nature, truth or just wishful thinking?
I mean, I'm curious too, and Vi's video is all I've heard about this correlation. I'm not asserting she's right, just that you might enjoy it. The video is called Doodling in Math: Spirals, Fibonacci, and Being a Plant.
