IS IT POSSIBLE TO CHANGE CANCER CELLS TO NORMAL CELLS?

   

Despite the development of numerous cancer treatment technologies, the common goal of current cancer therapies is to eliminate cancer cells. This approach, however, faces fundamental limitations, including cancer cells developing resistance and returning, as well as severe side effects from the destruction of healthy cells.

KAIST (represented by President Kwang Hyung Lee) announced on December 20th that a research team led by Professor Kwang-Hyun Cho from the Department of Bio and Brain Engineering has developed groundbreaking technology for treating colon cancer. This technology converts cancer cells into a state resembling normal colon cells without killing them, thus avoiding side effects.

The research team focused on the observation that normal cells regress along their differentiation trajectory during the oncogenesis process. Building on this insight, they developed a technology to create a digital twin of the gene network associated with this trajectory.

Through simulation analysis, the team systematically identified master molecular switches that induce normal cell differentiation. When these switches were applied to colon cancer cells, the cancer cells reverted to a normal-like state, a result confirmed through molecular and cellular experiments and animal studies.

This research demonstrates that cancer cell reversion can be systematically achieved by analyzing and utilizing the digital twin of the cancer cell gene network rather than relying on serendipitous discoveries. The findings hold significant promise for developing reversible cancer therapies that can be applied to various types of cancer.

Professor Kwang-Hyun Cho remarked, "The fact that cancer cells can be converted back to normal cells is an astonishing phenomenon. This study proves that such reversion can be systematically induced."

He further emphasized, "This research introduces the novel concept of reversible cancer therapy by reverting cancer cells to normal cells. It also develops foundational technology for identifying targets for cancer reversion through the systematic analysis of normal cell differentiation trajectories."

The Ministry of Science and ICT and the National Research Foundation of Korea supported the study through the Mid-Career Researcher Program and Basic Research Laboratory Program. The research findings have been transferred to BioRevert Inc., where they will be used to develop practical cancer reversion therapies.

  Learn How the NEW Nutrition Facts Label Can Help You Improve Your Health The US Food and Drug Administration (FDA) issued new regulations changing the  Nutrition Facts  label external  icon  on packaged foods. This is the first major change to the label since it was introduced in 1994. The changes are based on updated science, the most  recent dietary  recommendations, external  icon , and public input. Using the new label can help you choose foods for a healthy diet. The label will be required on all packaged foods made in the United States and imported from other countries. The new label is already appearing on packages. Most items will have the new label by January 1, 2021. What is changing? Calories & Fat Larger, darker letters make calories the easiest item to see on the new label. When it comes to health outcomes, the type of fat you eat matters more than the overall amount of fat. For this reason, the label will no longer show the per...

MUSCLES EXERCISING POWERS NEURON GROWTH AND REPAIR

  MUSCLES EXERCISING POWERS NEURON GROWTH AND REPAIR The findings suggest that biochemicals released during exercise and the physical effects of exercise could help heal nerves. Exercise is good for the body. Regular activity strengthens muscles and can strengthen bones, blood vessels, and the immune system. Now, MIT engineers have found that exercise can also have benefits at the level of individual neurons. They observed that muscles contract during exercise and release biochemical signals called myokines. In these muscle-generated signals, neurons grew four times further than neurons not exposed to myokines. These cellular-level experiments suggest that exercise can have a significant biochemical effect on nerve growth. Surprisingly, the researchers also found that neurons respond to the biochemical signals of exercise and its physical impacts. The team observed that when neurons are repeatedly pulled back and forth, similar to how muscles contract and expand during trainin...

CANNABIS, THE PHANTOM MENACE, MORE DANGEROUS THAN IMAGINED

  CANNABIS, THE PHANTOM MENACE, MORE DANGEROUS THAN IMAGINED  Scientists have known for some time that cannabis use has deleterious effects on health long-term. The evidence keeps piling up of how dangerous this drug can be.  A recent study conducted at McGill University showed how cannabis increases the risks of psychosis. These are just the latest concerns, as cannabis has also been implicated in increasing heart attacks and stroke risks, according to a study of 430,000 adults conducted by the American Heart Association. According to findings at McGill University, Young adults at risk of psychosis show reduced brain connectivity, a deficit that cannabis use appears to worsen. In the first-of-its-kind study, McGill University researchers detected a marked decrease in synaptic density -- the connections between neurons that enable brain communication -- in indivi...
