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.

      I am a medical oncologist and wanted to clear up the fact that inflammatory breast cancer is the worst type of breast cancer to have. Very aggressive treatment can get it under control but it has a very high rate of relapse. I hate being the bearer of bad news, but your friend should make sure that she is receiving state of the art combined modality therapy.

      The following information came from the Discovery Health web site:

      "Inflammatory breast cancer (IBC), which can also be Stage stage III or Stage stage IV breast cancer, is the least common but most aggressive type of breast cancer.

      While only 1 to 4 percent of newly diagnosed cases are IBC, 60 to 70 percent of all women with the disease do not live five years beyond their diagnosis. "

  2. RNAi Technology by Xeroc · · Score: 5, Informative

    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!

  6. There's several catches by PIPBoy3000 · · Score: 4, Interesting

    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.

    (I realise this is an important development for fixing human cancers, but as a pet owner - it would be great to have these working fixes for the little ones it's been demonstrated on!

    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.

    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.

    In which case it would most definitely be impossible for cancer to form.

    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.
