Researchers at Tel Aviv University have developed a new family of drugs that may enable preventive treatment for cancer, or turn cancer into a chronic disease that can be lived with for many years.

The research, which was conducted in the laboratory of Dr. Ronit Sachi-Painero from the Department of Physiology and Pharmacology at the Sackler Faculty of Medicine, will be published in September 2010 in the scientific journal FASEB Journal.

The new research is based on the idea that the development of a cancerous tumor can be stopped by damaging the process of creating the blood vessels that supply it with oxygen and nutrients - a process known as angiogenesis. The goal of the researchers was to test the effectiveness of innovative polymeric carriers, which are designed to carry drugs directly to the cancer cell - an advanced therapeutic procedure with important advantages: the substances do not harm healthy tissues, and the amount of substance needed is significantly reduced - so that the side effects of the treatment are significantly reduced.

The carriers, developed by Dr. Ronit Sachi-Painero, Dr. Paula Ofek and their colleagues at the University of Berlin, were connected to a siRNA gene silencing agent, and the compound was injected into laboratory mice with cancerous tumors. And the results were extremely encouraging: the carriers led the siRNA directly to the cancer cells, and the compound penetrated through the cell membrane and silenced the target gene - all this without causing the mice signs of poisoning that are usually characteristic of cancer treatments. Now that the effectiveness of the procedure has been proven, the researchers hope to launch into the cancer cell siRNA responsible for silencing a key gene, which is very important in the angiogenesis process. The silencing of such a gene may inhibit the blood supply to the tumor and starve it to death. The scientists also anticipate that it will be possible to use carriers for the selective transport of additional chemotherapeutic agents, thus increasing the effectiveness of the treatment without toxicity to the patient.

According to Dr. Sacchi-Painero, this type of treatment may bring about a real revolution in the medical treatment of cancer. People who are not sick, but are at high risk of developing the disease - such as former patients or carriers of mutations in cancer-causing genes - will be able to receive preventive treatment and continue their daily routine. In cases where the cancer has already broken out, the drugs will keep the tumor in a permanent state of dormancy, and will turn the cancer into a controlled chronic disease, with which one can live for many years with a good quality of life.

Dr. Ronit Sachi-Painero won the prestigious Juludan Award for 2010 on behalf of the Technion for her contribution to the advancement of technology in the world of medicine.

  1. Ami:
    The conspiracy theory with the doctors and the patent is also completely disconnected from reality.
    You can get medical marijuana in Israel - and people get it according to a doctor's prescription.

    Now I ask you to answer me another question that always bothers me when someone comes up with such crazy conspiracy theories.
    Are you claiming that people don't do things if they have no financial interest in them?
    I deny this, but if we go by your method: what is the financial interest that brings you to write the things? Or is your claim that everyone is acting only based on financial interest and you are not.

  2. You're kidding, are not you?
    How exactly does marijuana help cure cancer? As far as I know, this should generally help reduce the feeling of nausea caused by the chemotherapy treatments.

  3. In the meantime the best medicine for cancer treatment is "medical marijuana" they demanded it as soon as possible. The problem is that the treating doctors do not mention it, because it is not a medicine and it is not possible to register a registered patent on it, therefore there is no interest in encouraging its use, this is compared to chemotherapy for example which brings in capital and the chances of recovery with it are quite low. In my personal opinion, smoking marijuana can also be used as a substitute for steroids and pain relievers for cancer patients.

  4. Moshe,
    The method is based on inhibiting the growth of blood vessels to the tumor. Therefore, it is applicable only to local tumors that encourage the growth of blood vessels to them that bring them the nutrients. Lymphoma and blood cell cancers will not be affected by this method.
    The idea behind the above method is not new and in the past there was great hope from the experiments of the late Prof. Yehuda Folkman for an effective drug that inhibits the VEGF protein and thus prevents the growth of new blood vessels, an idea that ultimately did not yield the desired drug.

  5. A question for the experts: Is the new method also effective for blood cancers such as lymphoma. In these types of cancer, the cancer cells live in the bloodstream, therefore, the question is, can the developed method starve these cells as well?

  6. solution? We will leave one disease that will kill us (preferably heart failure) or we will decide to prevent most of the diseases of aging (which means revitalizing new cells, treating the physical infection, etc.) and stop having children. There are no other ways (unless we find other stars and/or find technologies that we don't yet have in our hands when the time comes).

  7. Michael,
    If you came out on me, then I brought up a close topic. I did not attribute my words directly to the current study, at least that was not the intention.

    Indeed, kudos to the guys from the article, nevertheless, the progress is really surprising. I have every hope that they will succeed in their efforts and we will see the results of the research as soon as possible, as the commenter Rotem hoped.

    However, I could not ignore the topic I was talking about. He is highly related and I have an interest in him. A thing that every mortal should have.

    And for the oncologist: population explosion is another matter! It should also be treated differently. Your words sound like Letz's words. Do you have a suggestion for a solution?

  8. Forgive me for commenting, but I see medicine as a disaster. If we cure all diseases, then how will people die? After all, then there will be a population explosion. And for the ignorant among you - "aging" is not a cause of death.

  9. what diameters
    Just unbelievable!
    People make an effort, research, and discover ways to deal with the diseases and there will always be uber wise people who know nothing who will come to them with complaints.

  10. supports fresh.

    This is a problem - today drug development is carried out on the basis of turning any disease into a chronic disease while reducing or neutralizing the symptoms. This is the most efficient mechanism for a company to sell the drug. This is the only way she will finance her activities. Therefore, as fun as it is, cancer will also become another disease that instead of eliminating the "customers" will leave them alive with a poor standard of living due to constant financial expenses and certainly side effects of one kind or another, while squeezing the long-standing pockets of the customers until the day of their distant death.

    The situation today is that people are getting older and along the way they collect more and more drugs that keep them alive and do not cure them! Today, elderly people keep stockpiles of medicines and are busy all day sorting out the sea of ​​pills they have to take.

    In my opinion, the solution to this is for rich and elderly people such as Warren Buffett and his friends to establish a foundation and fund it, whose role will be to take promising researchers and studies under its auspices and lead them without fear in the direction of healing instead of treatment. In front of them will stand enormous entities with their strength that will do everything to disrupt progress in research such as these (the entire pharmaceutical industry today, which probably generates more than billions per year). Therefore only very strong people will be able to co-operate and protect such a body. It is their interest as well as the interest of the general public.

  11. This is not an article about means of production. How cheap is the drug? Long years and expensive care do not go hand in hand...

  12. You also wrote "soon it will be good".
    And besides, it is only good for those who have cancer, the rest of the people will suffer forever with population explosion and lack of basic resources such as water, agricultural land, and energy.

  13. It is impossible not to be impressed by the increasing female involvement in all fields of chemical and medical research and by the achievements that are increasing as this involvement grows.
    This is a tumor that is the opposite of malignant.

    Align power.
