Nanomaterials Used in Possible Cancer Cure
Moiche writes "Medical researchers at CalTech and the Children's Hospital in Los Angeles have successfully inhibited cancer growth in mice by wrapping engineered RNA in nanomaterials and introducing them into the bloodstream. Two polymers and a special coating allow the therapeutic RNA to enter the cancer cell and release the therapeutic RNA payload. The new technique has slowed or prevented the development of secondary tumors in lab mice with Ewing's sarcoma. Further testing is planned on humans, and with other cancers. The Diamond Age seems closer, day by day."
A good friend of mine found out today that she has inflammatory breast cancer (IBC). I would like to belive that a technology like this could help her, but I don't think that she will ever get that chance.
This uses RNAi technology - that is the RNA they deploy is complementary to the RNA produced in Cancer Cells, and so they complement with the cancer RNA into a double-stranded piece of RNA - which screams virus - and the cell destroys it. Therefore stopping the growth of the cancer.
This method of using the nanomaterials to protect it and enable it to enter the cancer cells surely looks very promising!

The tricky part is that each individual cancer must have a particular treatment created for it. It's not a generic cancer cure, but rather one that can be targeted against certain very specific types of cancer. They'd need to know exactly what's genetically wrong with the cell in order to cure it.
Not only that, but if the iRNA sequence not only matches the problem RNA but also a healthy one, you could potentially be interfering with normal gene function. That's why they targeted Ewing's sarcoma, a cancer that "provides a clear and unambiguous target".
Finally, this doesn't seem to actually cure the cancer, but rather puts it into submission. Think of the cancer cell's nucleus spitting out bogus RNA, only to be chopped up by iRNA that matches it. You'd need to take the treatment essentially forever. Drug companies could make billions.
Unfortunately, the treatment is likely to be insanely expensive for humans. There won't be a mouse treatment because recouping the costs of developing the treatment would be effectively impossible.
Now before I get modded down, I be to remind whoever might read this that what I am saying is FACT. - bogaboga
Have you ever tried to changed your internal pH to be alkaline balance? I'm sure you haven't cause you would be dead. The body can only exist in a narrow range of pH to functional properly.
Have you ever tried to changed your internal pH to be alkaline balance? I'm sure you haven't cause you would be dead.
In which case it would most definitely be impossible for cancer to form.
The technique works!

Just as a fyi, the press release for Hu et. al.'s research can be found at the American Association for Cancer Research proceedings page -- it's more technical than the Economist article linked above, but is quite informative.
