Here, we propose a new strategy for the treatment of early cancerous lesions and advanced metastatic disease, via the selective targeting of cancer stem cells (CSCs), a.k.a., tumor-initiating cells (TICs). We searched for a global phenotypic characteristic that was highly conserved among cancer stem cells, across multiple tumor types, to provide a mutation-independent approach to cancer therapy. This would allow us to target cancer stem cells, effectively treating cancer as a single disease of stemness, independently of the tumor tissue type. Using this approach, we identified a conserved phenotypic weak point a strict dependence on mitochondrial biogenesis for the clonal expansion and survival of cancer stem cells. Interestingly, several classes of FDA-approved antibiotics inhibit mitochondrial biogenesis as a known side-effect, which could be harnessed instead as a therapeutic effect. Based on this analysis, we now show that 4-to-5 different classes of FDA-approved drugs can be used to eradicate cancer stem cells, in 12 different cancer cell lines, across 8 different tumor types (breast, DCIS, ovarian, prostate, lung, pancreatic, melanoma, and glioblastoma (brain)). These five classes of mitochondrially-targeted antibiotics include: the erythromycins, the tetracyclines, the glycylcyclines, an anti-parasitic drug, and chloramphenicol. Functional data are presented for one antibiotic in each drug class: azithromycin, doxycycline, tigecycline, pyrvinium pamoate, as well as chloramphenicol, as proof-of-concept. Importantly, many of these drugs are non-toxic for normal cells, likely reducing the side effects of anti-cancer therapy....

Thanks for posting this.
Wow, that would be something! Along with targeted immunotherapy, the landscape is changing. Good news.
Really interesting. Glad you posted this.
Also, they are 3D printing real human livers as we speak and are working on hearts, kidneys and many other organs. There will be no rejection issues since they’ll be using your cells.
I read that a couple of parents doing cancer research asked their 8 y.o. daughter what they should check out and the daughter suggested antibiotics.
as I understand it cancer does not grow where there is not a fungal presence.
kill the fungus starve the cancer
a fungal infection may or may not be a cause.
the negative body conditions that exist promote both cancer and fungus to grow. so they may or may not be causally related. fungus likes acidic conditions and a sugary/hi carb diet. so does cancer.
Friend of mine has an uncle in a trial in Boston.
Uncle had advanced COPD and otherwise healthy. 60-70 year old.
Stem cells were removed and instilled back in his lungs. After 5 tears on o2 he can breathe normally.
this is the future folks.
the possibilities boggle the mind.
In some ways the world is getting better. In many other ways it is getting worse. I notice you spend quite a lot of time making sure we all know about some of the bad things going on in the world.
It's good to see you post some good news for a change. I believe I know why you post so much of the bad, and it's a good thing that you do, and i'm glad you do it, even though many of your articles leave me disgusted.
But yes, we seem to be reaching an era where pretty much anything will be curable.
kill the fungus starve the cancer
I have never heard that. I have heard quite a lot of connections between cancer and viruses, but not fungus.
Includes pancreatic cancer - this would be a real breakthrough.....
Chickensoup, the stem cell treatment success sounds fascinating! I did not know anyone was getting this treatment in Boston. Do you have any other information, like clinic name or doctor? I have a young brother with COPD that is now being considered for a lung transplant. The stem cell treatment sounds like a much better alternative, or at least something to try before undergoing a transplant! So, if you have any info that could be shared, I would appreciate your help!
Interesting, if you combine this with the use of http://en.wikipedia.org/wiki/CRISPR (more on CRISP is in this very good article https://www.quantamagazine.org/20150206-crispr-dna-editor-bacteria/ and this 4 min youtube video https://www.youtube.com/watch?v=2pp17E4E-O8 )
I will email my friend and get the name of the hospital and study.
