In this blog and in my treatise Anti-Aging Firewalls – The Science And Technology Of Longevity I try to steer a mid course between scientific over-simplification and loosing readers because the content is too technical for them to fathom. I am aware that many readers possibly have to struggle to follow the details of some of my posts. The purpose of this particular post is to remind my reader that longevity science involves biomolecular and genetic complexity that is much deeper than what I discuss, or for that matter, that I am competent to discuss.
It is pretty much agreed that extraordinary longevity will require activation of critical longevity-related cell signal transduction pathways. Yet, those pathways are incredibly complex. As an example, here is a listing of papers in the current online issue of the Journal of Biological Chemistry having to do with Mechanisms of Signal Transduction. I list the titles to illustrate the naked underlying complexity involved. And there are thousands of other journals reporting research results every month of equal complexity that have potential relevance for longevity. I am not suggesting you read these items but you might find the titles interesting for illustrating the biomolecular detail involved. I am necessarily highly selective in what I cover in this blog.
