Doxycycline, Azithromycin and Vitamin C (DAV): eradicating cancer stem cells
- zmmmmm 3y agoCurious why this is not toxic for the mitochondria of real cells if it is so bad for the cancer cells? Is it because the therapy only blocks genesis of new mitochondria,and most people would have sufficient existing mitochondria to stay healthy through the course of the therapy?
- nik_s 3y agoThe mitochondria in many cancer cell behave abberantly. For example, in many cases, they can start promoting glycolysis, in process known as the Warburg effect. They're also involved in other processes such as apoptosis and cell migration. I'd hypothesize that these drugs target pathways or processes that are dysregulated in the mitochondria of those cancers.
- qbxk 3y agoi think it's because most cells have multiple forms of metabolism available to them, but cancer cells are limited to just this one

- vikramkr 3y agoThere better not be any comments on this thread about this paper from 2019 that didn't really make a huge splash and is entirely in cell culture that go "oh boy another cancer cure too bad they make it to the clinic." This is pretty much about as far from highly reliable and translation ready as you can get.
- cushpush 3y agoThis is amazing and I do not mean to nit-pick but does this statement logically cohere? >Also, the concentrations of antibiotics used here represent sub-antimicrobial levels of Doxycycline and Azithromycin, thereby avoiding the potential problems associated with antibiotic resistance.
- MrLeap 3y agoIf you don't have enough antibiotics to actually kill microbes, you aren't selecting for higher resistance.
- bratwurst3000 3y agoAntiobiotics don’t kill bacteria. They stop the growth and the body does the rest. Or am I wrong ?
- fastaguy88 3y agoYes. The concentrations of the antibiotics are too low to select for resistance, because they do not significantly affect bacterial growth. (Without selection, no resistance).
- Caduceus1 3y agoSomewhat puzzled they're using μM instead of μg?
- RF_Savage 3y agoMicro moles in serum maybe?
- chromatin 3y agoμM is a measure of concentration, while μg is a measure of mass. If you meant "μg/L" (or some other measure of volume), it is conventional to use molarity when discussing drugs in basic as well as clinical (PK, PD) contexts.
- giardini 3y agoHow do these dosages compare to the usual human therapeutic dosages of doxycycline, azithromax and vitamin C?
