Advises of cancer is no longer an incurable disease

Guided reading

Cancer is still a problem of people stranded, so many people talking about cancer. Because early cancers that are hard to find, treat painful process, almost everyone around us have heard or seen people who died of cancer. If we can create an edible probiotics, "compile" and is used to find cancer cells, then we can change cancer cells by collaboration between cells and eventually achieve the effect of a cure for cancer. This beautiful vision can really deliver? Can you believe it? Cancer is no longer an incurable disease!

1, our attractive "bacteria universe"

Maybe you didn't notice, the bacteria in your body more than the stars in the Milky Way Galaxy. This charming "bacteria universe" are indispensable components of our health, and the rapid development of high technology, allows us to deal with these bacteria like a calculator program.

This picture looks like some kind of map of the sports, but it is actually the first bacterial program developed by biologists. Like to write software code, we can output based on different algorithms and writing a sequence of DNA, and bacteria within the program, this app do is follow a rhythm producing a fluorescent protein, and generates a small molecule, allowing bacteria to communicate, information synchronization. The growing colony, and about the size of the width of a human hair.

But we fail to see how genetic programs to guide each of these bacteria produce molecules, which wanders between the individual molecules in thousands of bacteria, tells bacteria when opening and closing the corresponding function. In this scale, synchronization of bacteria is doing very well. Because these molecules move very quickly, in large colonies, the bacteria will cause far transmission fluctuations in the individual.

2, the "sensing" phenomena affecting the genetic program

Our genetic program relies on a technique called "quorum sensing" natural phenomenon and once the colony reached critical density, bacteria begin to stimulate coordinated, sometimes even have fatal consequences.

Growing colonies only when high density or the critical density is reached, will start to glow. Our genes program, when the colony spread outward, rhythmically and continuously manufacture fluorescent proteins. Because it looks like the stars, the big bang, this particular film and the experiment is called "Super Nova".

3, through the programming bacteria to fight cancer

In addition to compiling these beautiful drawings, but researchers are also thinking about what else they can do to explore "how to program bacteria" is a direction to detection and treatment of diseases of the body with bacteria, such as cancer. Bacteria is an incredible because they can grow naturally within the tumor, this is because the cancer is the immune system does not concern the General area. So when bacteria found at the tumor, the tumor as a haven, in which to grow, researchers have begun to use probiotics, they are safe and good for health. When mice oral probiotics, Probiotics will choose to grow in the tumor in the liver. The easiest mark probiotics, and tumors revealed, is that probiotics can be detected in the urine signal, so the researchers compiled these probiotics, can change the color of urine they produce molecules to achieve detection of cancer.

Researchers then demonstrated this technique on detection of hepatocellular carcinoma with high sensitivity and accuracy, and liver cancer is difficult to detect in other ways. If we know that these bacteria can pinpoint tumors, researchers tried to achieve not only can detect cancers and can compile to treat cancer. From the tumor therapeutic molecules, make existing tumors shrink, and is already in use "quorum sensing" program to implement this process.

We can also use certain encoding bugs to fix the cancerous cells, and ultimately cure cancer? Hope this day would come, the cancer problem in one fell swoop to conquer!.
