In light of a couple of articles and studies from the last months I've started to wonder if SENS couldn't do a preliminary investigation into their proposed therapies very soon.
Quercetin seems to spur senescent cells into death but is also a known inhibitor of AGEs formation, possibly the best one readily available and better than some experimental substances like aminoguanidine. A liposome or micele formulation of quercetin increases it's bioavailability in an experimental setup. Dasatinib and potentially some other cancer drugs have a similar effect.
Certain types of stem cell therapies are readily available, specifically mesenchymal and hematopoetic.
In experiment mesenchymal stem cells are capable of transferring mitochondria to cells with disturbed mitochondrial functions (but unfortunately not to ones with mtDNA mutations).
There are already some drugs capable of affecting the extra cellular matrix. In combination with quercetin they should give a good intermediate avenue for development in the short term. Furthermore a human engineered skin model was developed recently and that should sufficiently speed up the research from now on.
Last year a team of scientist successfully lowered the amount of lipofuscin from macular tissues with beta cyclodextrins.
So let's review what we have:
- A somewhat working therapy for senescent cells
- A method for inhibiting the formation of AGEs and in the last case scenario the ability to slightly remodel the extra cellular matrix
- Stem cell therapies
- which have an observed benefit for mitochondria as well
- A reagent capable of instigating a removal of some lipofuscin from cells
None of those are perfect or "complete" but they work well enough in the lab and right now a good result in the labs could go a long way both for changing the public opinion and the opinion of the medical community. And we still don't have a robust anti cancer treatment BUT the experiment could simply use a species with a low propensity to developing cancers - so rodents are potentially out of the question.
What do you think?
